The long-term use of the gas storage tank or after many years of use will inevitably cause rain, air, or humid atmosphere corrosion, which is caused by the action of water, oxygen, acid pollutants, and other substances in the atmosphere. Rusting of steel under atmospheric natural conditions is one of the most common atmospheric corrosion phenomena.
 
There are three types of gas storage tanks subject to atmospheric corrosion
 

•   Dry atmospheric corrosion. At this time, there is no water vapor in the atmosphere, and ordinary metals form an invisible oxide film at room temperature. The surface of the steel remains shiny.

 

•   Wet atmospheric corrosion. Refers to the corrosion of metals under a thin film layer that is invisible to the naked eye.

 

• The gas storage tank's corrosion under the liquid film condition can be seen. Refers to corrosion in the air with a relative humidity of about 100% or in rain and other aqueous solutions. 

 
Influencing factors of atmospheric corrosion
 

•  The influence of water. Among the substances that corrode steel in the atmospheric environment, water is the main factor (generally speaking, the higher the humidity, the stronger the corrosion)

 

•  The influence of SO2 (sulfur dioxide). In areas polluted by industrial waste gas, SO2 has the most serious impact on steel corrosion.

 
Therefore, we need to strictly abide by the maintenance rules, clean and clean in time, and make the product life longer

The cleaning of the air compressor includes the whole machine cleaning, the water-air separator, the cooler, etc.

In practice, if the air compressor runs for too long, will accumulate a lot of dust, oil, and various particles, and there will be oil scale, carbon deposition, sediment, rust, etc., so it is necessary to clean the internal parts of the air compressor regularly, to eliminate hidden safety risks.
 
The cleaning of the air compressor includes the whole machine cleaning, water and gas separator, cooler, and so on. Today, we will introduce it in detail.




1. Cleaning of the whole machine
 
First, run the air compressor for a few minutes, and the oil reaches normal temperature;
 
Close the air compressor, and when the internal pressure is relieved, open the refueling cover, pour in the air compressor cleaning agent, and tighten the refueling cover;
 
Turn on the air compressor and run it for 30 minutes;
 
Drain old oil, then add new oil;
 
Generally, the temperature of the air compressor will drop by about 10 degrees after cleaning.
 
2. Cleaning of water and gas separator
 
The structure of the screw air compressor water and gas separator is similar to the oil and gas tank, and the air inlet is designed against the wall, so it forms the centrifugal force, the weight factor of water and gas, so it can effectively separate the water in the compressed air.
 
The cleaning method is to open the cover of the water and gas separator and soak and clean it with a cleaning agent.
 
3. cooler cleaning
 
1. Water-cooled cooler:
Disassemble the cooling water inlet and outlet pipe; Infuse the cleaning solution to soak or rinse with pump circulation; Rinse with clean water; Install cooling water inlet and outlet pipes.



2. Air-cooled cooler:
Open the air hood to clean the cover, or remove the cooling fan;
 
Use compressed air to blow the dirt down, and then take the dirt out of the air hood; If it is dirty, spray some oil remover and blow again.
 
When the screw air compressor cannot be cleaned by the above method, the cooler needs to be removed, soaked, or sprayed with cleaning liquid and cleaned with a brush (strictly prohibited to use a steel wire brush).
 
Install a cover plate or cooling fan
 
3. Oil cooler:
 
When the scaling of the oil cooler is serious and the cleaning method mentioned above is not ideal, you can remove the oil cooler separately, open the end cover of both ends, and remove the scale with a special cleaning steel brush or other tools.
 
When cleaning the medium side of the cooler cannot effectively reduce the temperature, the screw air compressor needs to clean the oil side, and the steps are as follows:
Disassemble the inlet and outlet tubing;
Inject cleaning solution to soak or wash with pump circulation (recoil effect is better);
Rinse with clean water;
Blow dry with dry air or remove water with dehydrated oil;
Load the inlet and outlet line.
 
4, screw   air compressor temperature control valve cleaning
 
There is a side cover on the side of the temperature control valve of the screw air compressor, and there is a screw hole on the cover. Find a suitable nut to screw into the side cover.
 
Then use the spring pliers to remove the spring fix the side cover, and then use the pliers to pull the nut just screwed in,
You can remove the side cover and all parts inside.
 
Clean all components of the temperature control valve in the same way as cleaning load reducing valve.
 
5. Load reduction valve (intake valve) cleaning
 
Bilge is serious when such as inlet valve, change a new detergent when cleaning, cleaning process should be wash cleaner parts, after washing the dirt more components, components used water rinse again, to avoid corrosion and shorten the service life of components, wash clean parts in a clean place to dry, to avoid rusty iron parts.
 
When cleaning the place where the valve sheet and the valve body contact valve sheet, attention should be paid to the flatness of the surface, and it should be cleaned and replaced when necessary, otherwise it will cause the air compressor to start with load (the screw air compressor can not start when the large unit starts with load).
 
6. Minimum pressure valve cleaning
 
Although the minimum pressure valve in the screw air compressor looks small, don't look down on it. It controls the whole machine. All the more reason to be careful.
 
The structure of the minimum pressure valve is very simple. Unscrew the nut of the screw air compressor between the spool and the valve body to remove the components inside. The minimum pressure valve spool of the small unit is built into the valve body, and all the internal components can be removed by disassembling the valve body cover.
 
The minimum pressure valve can be cleaned according to the load reduction valve method. The minimum pressure valve of the screw air compressor is put aside to be loaded into the air compressor after the whole cleaning process is completed.
 
7. return oil check valve cleaning
 
The function of the oil return check valve is to recover the oil of the oil and gas separator to the host without letting the oil of the host flow back to the oil and gas separator.
 
Return oil single valve in the valve body has a connection, from the unscrew, remove the spring, ball, and ball seat.
 
Clean the return oil check valve: clean the valve body, spring, steel ball, and steel ball seat with the cleaning agent, and some check valves inside the filter screen, if any, clean them together.

Understanding the design function and working principle of each valve will give some help to the common fault solution of the air compressor!

No matter what brand (imported/domestic) oil injection air compressor, its compression working principle is the same, and the function of each valve is also roughly the same. If we can thoroughly understand each valve's design function and working principle, we will give some support and help to the common fault solution of the air compressor! 

The five valves of the Oil injection air compressor are the Unloading valve, Min pressure valve, Oil Stop valve, Check Valve, and Thermostatic valve. The functions and troubleshooting of each valve are explained one by one.

 

Unloading valve

 

Function:

When the gas consumption changes, the intake valve adjusts the opening degree of the valve body to match the gas consumption through the control system. It is the valve part that controls the gas production and no gas production of the air compressor.

Common corresponding faults:

1. The air compressor is not loaded. This fault control panel shows (no alarm; Run state 'load'; Injection pressure is very small or '0'; Nose outlet temperature < 70C°) can determine that the unit is not loaded. The problem lies in the unloading valve body, control loop, loading and unloading solenoid valve, and other parts, which need to be checked and rectified one by one.

 

2. The air compressor is not unloaded. This fault control panel shows (no alarm; Run state 'Unload'; Injection pressure increased > 4; Head outlet temperature > 80℃) can determine that the unit is not unloaded. The problem lies in the unloading valve body, control loop, loading and unloading solenoid valve, and other parts, which need to be checked and rectified one by one.

Min pressure valve

 

Function:

1. The opening pressure of the minimum pressure valve is about 4bar. Ensure that the pressure in the cylinder is not lower than this minimum pressure when the air is output, to avoid the reduction of the separation effect of the oil and gas separator caused by too fast air velocity.

 

2. When the machine starts, a certain pressure is established in the cylinder to ensure the lubricating oil circulation and provide the initial control pressure for the control loop.

 

3, with the function of a one-way valve, prevent the pipe network compressed air reflux to the machine inside.

 

Common corresponding faults:

1. Oil cylinder safety valve air injection during operation. This fault is because the minimum pressure valve is not opened, resulting in high pressure in the cylinder, the relief valve pressure protection.

 

2, running computer motor overload protection. This fault is that the minimum pressure valve is not opened, resulting in high pressure in the cylinder, the load of the main motor is aggravated, the current is increased, and the thermal relay protection stops.

 

3. The air compressor fails to start. This fault is that the minimum pressure valve is not closed strictly, resulting in the pipe network compressed air reflux, so that a certain pressure is generated in the cylinder, resulting in the unit can not start. When the air compressor starts, the control computer detects that there is a certain pressure in the oil cylinder, and the unit will not start.

 

4. The oil pressure of the air compressor is high when it is unloaded. This fault is that the minimum pressure valve is not closed strictly, and the compressed air in the pipe network returns when the unit is unloaded, which causes the pressure in the cylinder to rise, leading to an increase in oil pressure and the energy consumption of the unit.

 

 Oil Stop valve

Function:

After the air compressor is started, the oil cut-off valve is opened, and the lubricating oil passed through the oil filter is injected into the main engine. After the machine is shut down, the oil cut-off valve is closed, and the oil supply is cut off.

 

Common corresponding faults:

1. Jump off the machine at a high temperature quickly after starting. This fault is the oil break valve is not opened, and lubricating oil can not be sprayed into the nose, need to check and maintain the oil break valve.

 

2. High-temperature alarm of air compressor. This fault is that the oil cut-off valve is not fully opened and the amount of lubricating oil sprayed into the engine head is not enough. It is necessary to clean and maintain the oil cut-off valve.

 

3. When the machine stops suddenly, the lubricating oil is sprayed back into the air filter. This fault is caused by the delay or lax closure of the oil valve when the unit is suddenly shut down. It is necessary to clean and maintain the oil valve.

 

Check Valve

Function:

The compressed oil and gas mixture of the main engine is delivered to the cylinder in one direction to prevent the oil and gas mixture in the cylinder from spraying back into the nose and causing the rotor to reverse when the engine stops suddenly.

 

Common corresponding faults:

During the shutdown, the oil and gas mixture is sprayed back into the air filter. This fault is caused by the check valve being stuck or damaged when the unit is suddenly shut down. It is necessary to clean and maintain the check valve.

Thermostatic valve

Function:

1, temperature control spool through the principle of thermal expansion and cold contraction, extending and contracting to regulate the oil channel changes formed between the valve body and the shell, control the proportion of lubricating oil into the oil cooler, and ensure that the rotor temperature is within the control range.

 

2. The temperature control valve is the original to control the outlet temperature of the head not less than 68℃. When the oil temperature is low, the temperature control valve is closed, and the lubricating oil is sprayed directly into the head without the cooler for rapid heating so that the outlet temperature of the head rises rapidly and the condensed water in the compressed air is prevented from being generated in the oil cylinder.

 

Note:

1. The opening temperature of the thermostatic valve is generally marked at the spool.

 

2. The maximum opening temperature of the thermostatic valve is +15℃.

 

 

Air compressor repair and maintenance, overhaul the goal is to continuously improve and maintain the equipment maintenance level, in the most economic and reasonable life cycle cost and equipment to maintain good performance, ensure enterprise gas needs, improve the utilization rate, prolong the service life of air compressor, thus promoting enterprises to improve production efficiency and economic benefits.

Air compressor equipment maintenance mode

The classification of air compressor maintenance methods can be roughly divided into the following three categories:

The role of air compressor equipment overhaul, repair, and maintenance

Maintenance plays a very important role in air compressor management and enterprise benefits. It can be divided into the following points:

1. When the screw machine is running, the compressed air contains condensed water in the atmosphere. In the continuous operation of the machine, the oil temperature gradually rises to 80℃, and the condensed water in the oil starts to evaporate, and the water is discharged to the gas storage tank with the compressed air.

2. Due to the selection or user gas consumption being very small, the screw machine operation load rate is seriously low, which leads to the screw oil temperature can not reach 80℃ or above for a long time, and the oil and gas barrel starts to water, and the oil core load is a heavy and fast failure. In serious cases, the oil will deteriorate and emulsify, leading to the main engine rotor rust stuck.

    Air compressors have now become important industrial equipment, and become the main power source in major industrial enterprises. They are responsible for the healthy operation of enterprise equipment. In order to let the air compressor create infinite value for you, the design of the air compressor room is very important. , in line with the air compressor room design standards, not only can prolong the service life of the air compressor, but also make corresponding guarantees for safety. Today, let's talk about the serious consequences of not meeting the design standards of the air compressor room?

Consequences of not meeting the design standards of the air compressor room

1. If the water cooling unit of the air compressor is not purified, it will cause serious blockage inside the cooler, and the cooling function will gradually weaken, resulting in the high-temperature shutdown of the air compressor, carbon deposition in the oil circuit, increased power consumption, and unstable gas production. question;

2. If there is too much dust and oil mist in the air compressor room, it will affect the life of the electrical components of the air compressor (especially the inverter), and the iron powder will be sucked into the air compressor host, which will cause the screw to wear out, or even bite to death. Lead to electrical short-circuit shutdown, the high-temperature shutdown of the air compressor, and a decrease in the efficiency of the main engine;

3. There is no independent closed space for the air compressor. If the surrounding construction causes the cement to adhere to the air compressor, the dustproof sponge of the air compressor will be invalid, which will cause the air compressor to stop at a high temperature or the host to suck in sediment and bite to death;

4. The space of the air compressor room is small, and the environment is dirty, chaotic, and poor, which will not be conducive to the heat dissipation of the machine, regular maintenance, and relocation of the machine, resulting in the high-temperature shutdown of the air compressor, inconvenience in maintenance and relocation.

Troubleshooting of Air Compressor ''Jump''

---

The ''exclusion method'' can be adopted to rule out the causes of the failure one by one.

1. Pressurized starting 

2. The resistance of the machine head is too large

If the resistance of the machine head is too large, the starting current of the compressor will be too large, that is, the compressor is overloaded, causing the air switch to trip.

How to handle:

(1) Manual cranking is the most basic detection method for the connection and free rotation of the compressor power components, transmission components, and linkage components. Through manual cranking of the compressor before starting, it is checked whether the machine head and the motor can rotate freely and whether the resistance of the rotation increases or not is determined according to the previous cranking experience.

3. Failure of electrical equipment

Many users use 380V motors, which are started by the star-delta conversion step-down starting method. In the early stage, it runs in star mode, and after 2~3s of a startup, it changes to delta mode. If the star-delta transfer switch fails, normal star-delta conversion cannot be performed, the star-shaped current is many times higher than the delta operating current, and the protector delay time expires, which will naturally cause the compressor to trip. In addition, due to vibration and other reasons during the use of the air switch, the set start-up time is shortened, which may also lead to ''jumping'' at the moment of start-up.

4. Failure of the unloading valve

The unloading valve is an important part of the screw compressor. Its main function is to control the loading and unloading of the unit, that is, to control the air intake of the compressor.

5. High-temperature trip caused by thermostatic valve

Some high-temperature trips are not caused by external temperature or poor heat dissipation of the unit, but by poor operation of the temperature control valve.

6. High-temperature trip due to lubricating oil

Lubricating cooling oil failed. The lubricating oil of the air compressor not only lubricates the moving parts, such as the rotor and the vane that rotate at high speed. Moreover, a large amount of heat energy is generated during the cooling and compression process, such as friction heat generated by the relatively high-speed motion of the friction pair and heat energy generated when the air is compressed.

Q: After the compressor is turned on, it looks like it is working, but there is actually no air coming out. What can we do about it?

• Check the ultimate safety valve

   Whether the knob position on the top of the ultimate safety valve has been screwed to the top. If not, please turn it counterclockwise to the topmost position and try again.

Q: The set pressure of the compressor is obviously 330bar, why can't the air be charged when it is charged to 20bar?


 

• Check the ultimate safety valve

       Is the safety valve leaking, has it been screwed all the way? The knob on the top of the final safety valve is not set to the operating position, please turn the knob to the operating position.

 

• ​Check the extension board

  At normal temperature, the maximum length of the external cable (three-phase motor) is 25m.

Q: The compressor cannot be started

• Check the phase sequence

  If the compressor has phase sequence protection and the phase sequence is reversed, the phase sequence protection indicator light of the start machine will turn on red.
  Swap any two connectors of the three-phase connector in the switch box. Remember, the connectors cannot be swapped in the junction box of the motor.
  
   

Q: Why does the equipment keep low oil pressure alarm?

• Check if the motor is reversed

      Make sure that the direction of the motor is the same as the direction indicated by the arrow on the sticker on the device. If you find that the steering is inconsistent, adjust the phase sequence.

Q: Why does the motor have no response after turning it on?

• Check if the phase sequence is reversed

If the compressor has phase sequence protection and the phase sequence is reversed, the red light of the phase sequence protection indicator lights up after starting the machine, and the motor cannot run.

Q: Why does the pressure gauge not reset to zero?

• Check that there is still gas in the hose.

If there is air in the hose, the pressure gauge cannot be 0.

Q: When inflating, there is no air pressure coming out of the inflation tube, the pointer of the pressure gauge does not move, and it will automatically stop.

• Please pay attention to check the voltage

Please use a 230V, 16A socket, a multi-strand cable with a size of more than 4 square meters, and do not use a drag line socket.

Q: Is the filter cartridge leaking?

• Check if the filter element is installed

If not, please install the filter first

• Check that the O-ring of the filter element is intact

Replace O-rings if damaged or broken

Your air compressor is one of your most valuable assets and is a highly complex machine. Knowing how to troubleshoot an air compressor is crucial when it fails. This is a major investment for any company because it allows you to quickly see where the problem is.

10 Crucial Tips for Dealing with Too Loud Air Compressor Running-

• When the compressor is running too loudly, there can be many problems, such as loose pulleys, flywheels, belts, coolers, or accessories. Tightening any of these might help. You may also want to fill the crankcase with oil and inspect the bearings for any damage. Floor mounts may also be loose and need to be tightened. You may also need to replace the vibration pad at this point.

• Insufficient air pressure: There may be a leak somewhere in the compressor line. At this point, it is important to check the hose or pipe for leaks or restrictions. This is easy to fix if you find something. It may also be necessary to clean or replace the air filter to improve pressure or airflow. There are ways to reduce the pressure drop in the system.

• Air is blowing out of the intake valve: One cause of this could be a damaged first-stage intake valve. In this case, the valve assembly needs to be replaced. Excessive belt wear: Excessive belt wear can have several different causes.

 

• The pulley may be misaligned, in which case it just needs to be realigned with the compressor flywheel. If the belt is too loose or too tight, the tension will need to be readjusted. If there is wobble, you can check the warning crankshaft, keyway, or pulley hole. These things can be caused by loose pulleys.

• Excessesive blown fuse: If this is a recurring problem for you, it might be as simple as checking the amperage and rating of the fuse for proper use. There may also be low voltage in the system, or a defective unloader or check valve. It may be time for a replacement or repair. You also need to check the belt to see if it needs to be loosened.

• Excessive oil consumption: Any number of issues can have an impact on increased oil use. Air intake may be restricted at this point, which can be resolved by cleaning or replacing the air filter. If oil leaks are the culprit, tightening the bolts or replacing the washers will do the trick. Piston rings may also need to be replaced. If you use the wrong oil viscosity, you will need to drain the oil and refill it with the proper viscosity. If the compressor is running on a tilt, it will need to be leveled. If there are nicks, you may also need to replace the cylinder.

• Too much moisture in the air: If you are dealing with excess water in the compressor tank, you will need to shut down the system, lower the pressure, and drain the water. Installing an air dryer or air filter will minimize the amount of moisture in the air used.

• Compressor Vibration: If the compressor continues to vibrate, the mounting bolts may be loose. In this case, they may just need to be tightened. Installing a vibrating pad might be another way to reduce this problem.

• There is no pressure in the receiver when the compressor is off--probably just a faulty check valve. If this happens, the tank will need to be deflated. You can disassemble the check valve assembly and clean or replace any faulty parts.

• The compressor stopped working-probably just a power outage. You can try plugging the compressor into a new power source. A bad unload valve can also cause the compressor to stop working. If so, it may just need to be replaced.

When Troubleshooting Doesn't Work Sometimes Contact a Professional 

Sometimes, replacing or tightening the problematic part may not be enough. If you've tried your best to troubleshoot your air compressor and you're still having problems, it may be time to contact compressor service. It also helps to remember that preventive maintenance helps troubleshoot these problems before they occur. Our experienced technicians can help ensure the job is done correctly. If you have problems with your air compressor, please contact us today!

How to save energy and reduce carbon and save the earth? Start with reducing carbon emissions

For every extra kilowatt-hour of electricity that humans use, there will be one more carbon emission, because each kilowatt-hour of electricity (1000 watt-hours) will produce 0.554 kg of carbon emissions, assuming that one person runs an air conditioner (power consumption is 900 watts) every day Driving for 8 hours for a week consumes 50.4 kWh of electricity, which means that about 28 kilograms of carbon dioxide are emitted this week. However, if it is adjusted to only operate the air conditioner for 4 hours a day, then the carbon emission can be greatly reduced by 15 kg. It can be found from this that it is actually quite easy to reduce carbon emissions as long as you have the will. Each person can make a contribution to the green environment of the earth by turning on the air-conditioning for a few hours a day.

 

Therefore, the goal of carbon reduction can be achieved by means of saving energy. More ways to reduce carbon emissions are as follows. We all do our best for the earth.

 

1. Cool air temperature set to 28°C

2. Use energy-efficient appliances

3. Bring your own shopping bags and cutlery

4. by public transport

5. Using renewable energy to generate electricity

We are proud to announce that ACPARTS Air Compressors are now certified as energy saving air compressors by MyHIJAU.

Technology offers the answer to much needed cost savings
Lim Shu Chinq, 20 July 2020
 
   Just when our South East Asian region is supposed to begin the recovery and reopening phase from the disastrous COVID-19 lockdown, we are yet again being bombarded with news of further retrenchments by local conglomerates. This time from Resort World Sentosa (RWS), which by the sheer volume of its employee number is certainly one of Singapore’s biggest companies. While we have all heard and expect job cuts in the aviation sector due to the fear of flying sweeping mankind these days, what makes the RWS retrenchment more striking is that for the 1^st time in its illustrious 55 years history, the parent company of RWS, Genting Group has to exercise retrenchment for its Malaysia and Singapore branches.
 
   News like this make for bad readings for the majority of SME that makes up the vast majority of private-sector employment for the general public. In this article, I would like to delve a little deeper into ways that employers out there can safe some much needed money to avoid the dreaded job-cuts that seems inevitable.     
 
Hiring and allowance freeze
  While cutting salaries of staff seems the easiest way out, it’s really not advisable and should only be used as a last resort. This is because extensive studies have shown that staff going through salary cut generally have a worst time struggling to adjust to their new life post-salary deduction than those who have been unemployed for a longer time. Staff going through salary-deduction would exhibit lower morale and lower productivity and the negative vibes going through the organisation is rather contagious and would certainly affect the long term growth prospect of the companies concern.
 
   While salary cuts are not advisable, hiring freeze and freezing of certain allowances benefits for certain staff is more acceptable. Staffs who are given fixed travel allowances should be asked to forgo the allowance and instead harness the power of technology by using apps such as Zoom or Google Meet to meet clients or do products presentation. The amount saved could be substantial especially when the travel involves flight to faraway destinations. Entertainment allowances could be eliminated or reduced as well in the process as online meet-ups or meetings would mean there is no longer any need for hosting expenses.
 
    Likewise, by implementing hiring freeze, employer should take advantage of all the online courses available to retrain and educate their staff to be better equipped to do cross-section work. An admin staff could be trained to handle accounts as well and a sales staff could be trained to handle IT related work for the company as well. Therefore, there is less need to hire additional staff while at the same time, productivity and efficiency of the organisation would increase as most, if not all employee would surely opt for more work for similar or additional salary than a salary cut for similar work rendered.
   
 
 
Electricity efficiency
      Companies should also look at various ways to cut their so called “fixed-cost” through the power of outsourcing, renegotiation and research. For example, is it really necessary for a company to possess numerous company cars with all the maintenance, fuel and capital cost involved to do product delivery when there are reliable and much cheaper services like GrabExpress to deliver your goods for you? As for renegotiation, in the current economic climate we are in, it’s pretty much a given that other companies would rather earn less from your company than earn nothing so every negotiable items should be explored. The main supplier of your company’s blank paper, the daily cleaning service, the supplier of raw materials for your company’s production and so forth could all be renegotiated to your advantage. As the age old business phrase goes, well “It’s nothing personal, it’s just business”.   
 
      As for the research part, every employers knows electricity cost is one of the top cost of operating a business apart from staff compensation and rental of business workplaces. However, have we been taking proactive ways to safe on electricity cost? In the humid and hot weather climate of Malaysia and the South East Asian countries, air conditioning is a must and every workplace usually has plenty of units installed which is open throughout the duration of their operating hours.
 
    Take an average whereby operating each 2.0 HP (horsepower) unit of air conditioning 8 hours a day for 30 days would cost RM105.00 (based on 2015 TNB calculations), a typical office with 10 units of the said air conditioning would incur RM1050.00 per month in electricity bill from those air conditioning alone. By switching all their old units of air conditioning to the latest inverter system air conditioning for similar HP, they could save up to 40% from their bill which amounts to RM420.00 per month. At a cost of roughly RM2300.00 per unit for high quality 2.0HP efficient Inverter air conditioning unit, the company would have to come out with RM23,000.00 for 10 units which can easily be paid in interest-free installments. Supposing the old units are traded-in at a conservative rate of RM600 per unit to the selling company, it would take less than 3 and a half years to cover back the switching cost. In effect, the extra cost being save pays for the instalments of the new air conditioning and beyond the 3^rd year, the savings for the company will start to be rather significant.
 
    This savings method become even more significant for factories needing high voltage for long periods. Typically, its normal for these factories to incur electricity bills in the 5 to 6 digit range per month. One often overlooked power consumption unit is their factory’s air compressor units. Overtime, performance of their air compressor units deteriorates and often times, it is left untouched until major repair is needed.  However, by switching their old air compressor units to newer ones with Inverter Technology, they can easily save enormous amount in their electricity bill. An Inverter Type (or known as Variable Speed Driven) Screw Air Compressor typically saves between 35% to 50% electricity over regular Screw Air Compressor. At a conservative factory average usage of RM15,000.00 electricity bill a month from their air compressor units alone, a 35% savings equals to RM5,250.00 savings a month and at that rate, the switching cost of a new Inverter model 50HP air compressor costing an average RM50,000.00 would only take 10 months to earn back the capital invested. Beyond the 10th month, it’s like using the machine for free with great savings to boot. Talk about money well spend! Just be sure to look for experts in air compressor system in order to achieve full efficiency.
 
   So as we can see, there are indeed many ways for each and every companies big or small to safe much needed money over the long term. In fact, failure to change with the times could spell disaster in this era of economic uncertainly.
 
 

Air compressors  are versatile machines and perform a variety of tasks when attached to pneumatic tools. They have many applications, types and capacities, which can be confusing if you are not familiar with the world of compressors. We want customers to be able to clearly understand products before you make any decisions.

1. Air compressor sold by ACParts

The air compressors sold by ACParts are divided into two types. The  piston air compressor which sometimes wheeled, or can be mounted on a cart or small vehicle and will enable use of small tools on work-sites, it can be support 2-15hp only ; Another is screw air compressor, it can provide a steady supply of compressed air, are heavy duty, and have more detailed features. These compressors can power multiple tools at higher pressure continuously and are used in industries, it can be 10-200hp above.

2. Type of compressor: Single or two stage?

Single-stage air compressors are low capacity and the smaller models can be moved manually. These are for applications like air brushing, for small shops and homes. They have varying capacities and may also include a small storage tank for compressed air in larger models.
Two-stage air compressors are for garages and manufacturing facilities and can provide enough power to simultaneously run several air tools. These models compress the air twice, have storage tanks, and are therefore priced higher. Tank sizes can go up to 10,000 liters and beyond, and hold a lot of compressed air, which lets you reduce the input power consumption.

3. Capacity and delivery of the air compressor

Your air compressor’s capacity and delivery will depend on these factors:
PSI – Pounds per Square Inch:  A higher PSI is more compressed air for a given tank size.
CFM –The amount of air delivery possible in Cubic Feet per Minute. A higher CFM is more practical when the number of tools being used increase.
HP – The amount of power produced by the compressor motor. A higher horsepower produces greater PSI.

4. Screw or piston compressor?

Piston air compressors typically provide lower air output and lower air quality. These also generate more noise and work at higher temperatures. They may need more maintenance at a given duty cycle. They also consume relatively more power for a given output. Selecting a rotary screw compressor improves reliability, improves air quality, reduces energy costs and reduces maintenance. In the long run, these will make up for any additional costs.

5. Inverter control and synchronizing improve power saving efficiency

The screw air  compressor equipped with the Inverter control is used for the working condition in which the gas volume of the gas end varies greatly, and the Inverter control unit adjusts the rotation speed according to the actual required gas volume, thereby greatly reducing the energy consumption by more than 35%. When the inverter starts, the motor starts smoothly and does not generate peak current. According to the actual situation, the synchronizing can avoid the frequent start and stop of the air compressor, damage the equipment and reduce the impact on the power grid, and achieve an economic and stable operating state.

6. Choose the right air compressor manufacturer and supplier

Despite the many manufacturers, your new compressors will need to be reliable and require good support over their useful life to keep them in top condition.

Do you want to contribute to a greener environment? Are you trying to find appliances that don’t consume a significant amount of natural resources? If yes, then you should start using oil-free air compressors.

Anything that uses oil increases the carbon footprint in the atmosphere. It eventually leads to global warming, and everyone knows how that affects the earth. You can take the first step to save the planet by using oil-free air compressors. They are not just eco-friendly but also more efficient than traditional air compressors.

Engineers these days are trying to come up with devices that require less energy without compromising their performance. One of the best products they have come up with is an oil-free air compressor. Many reasons contribute to the popularity of this device including:
 

Consumes less energy

When you use oil-free air compressors, you benefit from two ways: first, it consumes less energy. This means you will not have to pay a significant amount of money for electric bills at the end of each month. It is a huge relief for those who want to save the planet while keeping more money in their pockets. Fluid-are dynamics air compressors, for one, is one of the companies that provide a variety of these energy-efficient products with different capacities. You can select one that suits your daily needs and stop paying hefty energy bills every month.

Another benefit of oil-free air compressor is it puts less pressure on your facility’s resources. Therefore, all the other systems can run efficiently because they don’t have to focus only on the air compressor.
 

Improves air quality

Oil-free air compressors can improve air quality to a great extent. They don’t emit hazardous wastes or gases that may harm the environment. The absence of oil in the entire system doesn’t allow smoke to pollute the air, thus contributing to a greener environment.

No oil contamination

Oil contamination can ruin products and slow down your production stage. It increases the time for which your facility works. Longer hours mean more money spent on labor. That’s the problem with traditional compressors. They run the risk of oil contamination. Once there is oil contamination, you cannot make the compressor work until it goes through full servicing.

This kind of problem doesn’t happen with oil-free air compressors because they don’t use oil in the first place. There are no risks of contamination. That means you can save a lot of money on heating, lighting, running tools and machines, cooling systems, and labor. A small investment in an oil-free air compressor can go a long way to saving a lot on additional overheads. It can reduce your delay in production, making everyone happy because no one has to work for long hours.

Conclusion

Every person has to come ahead and contribute if they want to save the planet. Even the smallest contribution can help to keep the earth clean and green. Using oil-free air compressors is one of the ways you can achieve that objective. Your action can encourage thousands to follow in your footsteps in the future.

BUSAN, Nov 25 — Prime Minister Tun Dr Mahathir Mohamad said the government intends to develop Malaysia to be part of the Fourth Industrial Revolution 4.0 (IR 4.0) and use modern technology to its advantage.

Speaking at the Asean-South Korea Commemorative Summit here today, Dr Mahathir said among the most promising industries in Malaysia is Information Technology (IT) and new technologies.

“We may be behind many others but we intend to catch up.

“We need to educate from young where they are more familiar with the new values, new strategy of doing things and new kinds of businesses,” he told a full house session moderated by Yoon Sung Woon of Bain and Company.

The local partner of the global management firm also asked Dr Mahathir on policy changes brought about by the new government as well as the country’s transformation plans.
 

The premier said Malaysia has always been welcoming towards foreign countries and investors, and this is still relevant despite the change in the government.    

However, he said, the government now is strict about combating corruption and does not accept any discrepancies in financial management.

“We still welcome foreign investors,” he said, adding that the fastest way to develop is by inviting foreign investment and acquiring technology.

The CEO Dialogue session, organised by the Korean Chamber of Commerce and Industry, is held in conjunction with the two-day summit which begins today with a leaders’ welcoming dinner.

Later, the prime minister visited the Malaysian Pavilion at the Invest Asean Exhibition held in conjunction with the summit.

Malaysian exhibitors participating at this event are MIDA, Matrade, Invest Selangor, Halal Development Corporation, Usaha Strategik Sdn Bhd (USSB), We Build Easy Sdn Bhd and Tourism Malaysia Seoul.

It is expected to receive 10,000 visitors.

Dr Mahathir was briefed by USSB, which produces biomass pellet from oil palm empty fruit bunch.

Its executive director Za’im Hadi Meskam said the prime minister was interested in how the local company developed the product.

USSB initially collaborated with a German company to acquire technology to produce energy pellets from biowaste but later switched to a technology partner from China.

“About 60 per cent of the technology was developed locally and our product is now used by an industrial boiler in Johor,” he said. — Bernama

Drawbacks of insufficient lubricant for air compressor

 

1. Will lead to overheat and damage the machine

If the lubricant is insufficient or improper, after the air compressor has been working for a period of time, some of the parts will melt or expand and lead to damaging of the machine.
 

2. Sound and environmental pollution

When there is insufficient lubricant, the operation of the compressor will lead to some noise and might damage bearing and gear. In some circumstances, noise are affected by poor transmission or misplaced gearing. In this case, it will affecting the production and polluting the environment.
 

3. Machine not performing, wastage

During the working process of the air compressor, without proper amount of lubricant, the transmission parts might get stuck and lead to low performance of the machine. In this case, the air compressor will not be able to perform normally and the consumption of energy will increase proportionally.
 

4. Oil Spill

After the air compressor is running for a period of time, the oil from the cabinet might leak due to the damage of the screw or seal rings. Frequent cold start (oil produces foam) or too high oil level will lead to oil leakage. These will result in environment pollution.
 

5. Poor friction lubricant, lead to wear and tear

In conditions that the machine are lack of lubricant, the gearing are unable to work normally. The gear will be worn and spoilt easily. When the tooth surface of the gear is tear, the air compressor will be unable to work and perform normally, same goes to the bearing in the machine.
