What Causes Air Compressor Pressure

Pressure drop may be a technical term want to reduce atmospheric pressure from the discharge end of a compressor to the equipment using the gas. Pressure drop occurs when compressed gas passes through the gas handling and distribution system.

In a standard compressed gas system, the pressure drop should be but 10% of the compressor discharge pressure, measured from the air tank to the gas user.

If the pressure drop exceeds 10%, this results from a compressed gas system operating inefficiently and consuming tons of electricity.

Therefore, reducing the differential pressure of all components within the system is an integral part of achieving better operating efficiency.

Common localized problems include coolers, oil separators, and check valves. A general rule of thumb for systems within the 7 bar pressure range may be a 0.1 bar neck drop by pressure when at discharge pressure; energy consumption will increase by approximately I Chronicles of the output flow.

Another problem is that the set pressure is above needed. Then the airflow will decrease, and therefore the power consumption is going to be higher.

What causes pressure drop in a compressed air system?

Any blockage, roughness within the system is that the explanation for the pressure drop. In distribution systems, the very best pressure drop is usually detected at the purpose of use.

On the availability side of the system, oil separators, coolers, condensate traps, air dryers, and filters also can cause significant pressure drop.

The maximum pressure drop from the supply-side to the purpose of use will occur when the ratio of compressed gas flow to temperature is highest. Compressor system components should be selected supported conditions, and therefore the manufacturer of every compressor component should provide information on the pressure drop under each state.

When purchasing accessories or equipment for a compressor, you should work together with your supplier to discuss specifications for differential pressure and other characteristics to make sure they’re compatible.

Causes affecting pressure regulator on air compressor

The three main reasons that affect the compressed gas pressure of air compressors are:

Due to the compressed gas pipeline: your compressed gas duct is broken, causing the airflow to leak. Your compressed gas pipe is poorly designed, and therefore the compressed gas pressure is reduced.

Using a compressor that’s too old isn’t enough to satisfy the compressed gas needs of your entire system.

There are too many devices that use compressed gas within the system that the machine must provide, but you select the steam compressor that doesn’t have enough capacity.

Optimizing pressure drop in compressed air system

Optimizing pressure drop requires a system that must be designed and maintained consistent with standards. Air handling components like coolers, water traps, air dryers, filters are selected with rock bottom pressure drop to optimize operating conditions.

When installing the system, it’s necessary to carefully study the manufacturer’s advice, advice, and proposals. Additionally, here are a couple of ways to assist reduce pressure drop by your compressed gas system:

  • Selecting the acceptable system distribution unit.
  • Operate and maintain air filters and drying equipment to attenuate the consequences of stagnant water on the system, like corrosion of airlines.
  • Select coolers, water separators, dryers, and filters with rock bottom pressure drop under the assessed condition.
  • Minimize the space between the gas user equipment and, therefore, the distribution system. In other words, the terminal distributes the gas to the ultimate gas user as close as possible.
  • All replacement equipment must be compatible with the compressed gas system utilized in terms of specifications, differential pressure, and operating efficiency.

Any replacement equipment must be compatible with the compressed gas system in terms of specifications, differential pressure, and operating efficiency.

Currently, some units have found an answer to the matter of pressure drop and not enough gas for the system by increasing the compressor’s compression pressure or adding compressor capacity. However, we should always only do that after finding other alternatives like reducing the working stress of the machine and storing compressed gas. 

Equipment should be operated with rock bottom pressure required to satisfy production requirements.

Why Is It Necessary To Adjust Pressure Regulator On Air Compressor?

During the operation of your high-pressure compressed gas pump, it’s inevitable that unexpected incidents like compressed gas pressure will be too high or suddenly lowered. This may have serious consequences that affect the productivity of the whole system.

Three leading causes affecting compressed gas pressure

  • You crammed air loss on shortened gas ducts. Because your tight gas pipeline is poorly designed or during operation, the pipe may leak, leading to a decrease in compressed gas pressure. Therefore, you would like to possess an idea to style compressed gas pipelines to be best.
  • There are too many devices that use compressed gas within the system, but you select a compressor that doesn’t meet the compressed gas flow source for those systems.
  • You use an old compressor, so it cannot meet the compressed gas needs of the whole system.

Therefore, adjusting the compressed gas pressure within the compressor system may be a must-do best to meet the compressed gas requirements of the whole system.

  • Having your compressor depressurized can cause consequences such as:

Your work productivity is significantly reduced, affecting the productivity of the whole system.

The pressure drop causes the compressor to work continuously for an extended time, which consumes more power. For each 0.1 bar of pressure drop, the consumed energy depletes approximately 1% more output flow.

Therefore, the immediate remedy of the matter of pressure drop for the compressor must be done quickly.

Instructions To Adjust The Pressure Regulator On Air Compressor Easily

The compressor’s relay is liable for protecting the air compressor, automatically disconnecting and turning on the machine when the device has provided enough pressure for the system or just in case the quantity of gas within the tank is less than the extent—got to use. The most pressure relay may be a device that controls and contributes to pressure protection within the pipeline.

This device is employed to convert pressure signals into switching signals of electrical contacts (which are ON/OFF buttons). This may help users to be proactive in their work—pressure regulation of the compressed gas system.

Pressure relay parts are divided into many sorts and have many various sizes. This device aims to offer the user maximum convenience and safety. That’s why the relay is one of the indispensable parts of the compressor in regulating pressure. 

You should equip yourself with the knowledge of adjusting the pressure relay for your screw or piston compressor. This may help the device work stably and efficiently. Instructions to regulate pressure by the relay in only 3 minutes:

1. For no-load pressure regulation:

  • Proceed to loosen the upper locking nut.
  • Proceed to show the bolt to regulate the no-load pressure within the same direction as clockwise to extend the no-load pressure and the other way around to scale back the no-load stress.
  • Tighten the upper locking nut.

2. For load pressure regulation:

  • Proceed to loosen the nut on the lower buckle.
  • Use the nut to regulate the differential pressure clockwise to decrease the pressure or turn counterclockwise to extend the pressure.
  • Tighten the lower locking nut.

Besides, this also has limitations such as:

  • Causing the compressor to work continuously with a better pressure than the manufacturer’s recommendation may cause the machine to fail to ensure its service life.
  • The system consumes more power than usual, costing you a considerable amount of additional energy for this part.

Adjusting Compressed Air Pressure

  • Components and parts participating within the pressure regulation of the air compressor: the cylinder part, the valve part is connected to the counterweight by a rod, this pressure regulating element also will be connected to the system. The gas supply system is additionally connected to the presser by two different installed pipes.
  • The parts that affect the pressure regulation of the compressor include: the cylinder part, the valve is connected to the counterweight by a rod, these pressure regulators also will be connected to the system. Gas supply and press mechanism by two pipes installed differently.
  • Between these two values, there’s a close relationship: the gas consumption of the entire system is adequate to the machine’s capacity. The pressure value will reach a worth well to the rated value. The manufacturer gives the extent, and the other way around, if the compressed gas consumption of the system is more significant than the machine’s pressure, the pressure value will be reduced.
  • The drive system of Piston compressors usually uses an electric motor or a rotor asynchronously designed engine with a continuing rotational speed so that you adjust the pressure of the machine. suffering from the opening and shutting of the valve assembly on the body of the machine
  • For air compressors using 220V power, the air compression relay will be adjusted to the pressure of about 8kg, and for air compressors using 380V power, the compressor relay will is changed to a force of 12kg. However, these also depend upon the source of compressed gas to be used.
  • To adjust for the relay to automatically disconnect, you initially got to open the relay cover, turn the relay clockwise if you would like to extend the pressure, and proceed to show the relay counterclockwise to urge compressed gas pressure are often reduced.

To completely overcome the limitation of pressure regulation

  • Choose to buy an air compressor that is suitable for the power consumption of the entire system.
  • Carry out regular compressor maintenance to ensure the best possible performance.
  • Maintain compressed air pipelines such as air compressor steam lines, self-retracting compressed air pipes to avoid loss of compressed air, causing the compact air system to drop pressure.
  • Select the size of the pipe to match the airflow in the system.

Common Problems With Air Compressors You Must Know To Handle

  1. Air compressor heat problem

This is probably the only common problem for air compressors, especially within the summer. 

Heat is caused by many reasons, including reasons such as the temperature of the compressor is just too high, the oil cooler isn’t working efficiently, and therefore the compressor maintenance time isn’t followed. the most cause isn’t changing the oil periodically, mechanical collisions, faulty thermostatic valves, damaged cooling fans. For every reason, we’ve our detailed treatment instructions.

  1. Oil and water in compressed gas

Oil and water present within the output compressed gas will severely affect end-use applications, such as wetting equipment resulting in product reprocessing, damage to gas tools. 

The foremost common causes of this phenomenon are the inefficient oil separator filter, insufficient minimum pressure valve, the machine running at heat for an extended time, not installing gas treatment equipment. (air dryers, filters) or poorly installed, water traps are inefficient.

  1. Air compressor suction valve oil leak

Oil leakage also referred to as suction valve oil loss, maybe a pretty common phenomenon when the compressor stops or operates at no load. 

The foremost common causes of compressor leaking suction valve oil are: improperly arrested compressor, instrument panel failure, an excessive amount of oil being poured within the machine leading to oil overflow, one-way valve, and valve damaged oil stop.

  1. The Air compressor is overcurrent

The compressor is overcurrent thanks to the following reasons:

  • The compressor is overcurrent.
  • The present supplied to the motor is just too high, the present sensor is broken.
  • The compressor head is wrong.
  • The oil separator filter is broken.

When the compressor is overcurrent, the alarm devices will immediately receive a sign and notify the instrument panel to prevent the machine.

  1. The compressor doesn’t reach the set pressure

You set the pressure for the compressor, but the pressure isn’t reached because of the norm you set. At now, your compressor has encountered a pressure drop. Pressure drop results in not getting the availability pressure for the system or tools that need compressed gas. 

Therefore, the pressure drop also results in an enormous loss of power consumption. With compressed gas systems, there’s always the matter of pressure drop. However, the pressure drop shouldn’t exceed 1 bar. 

Most are designed with a pressure drop of no quite 0.1 bar with today’s new air compressors.

  1. The air compressor doesn’t start

In the production shift, you press the button to start the compressor but don’t see the signal that the machine works. At now, you would like to see the causes: is that the voltage is applied to the device? 

Are there any indicators displayed on the warning screen? Check the starters. Is the motor spinning or not?

  1.  Low pressure in the compressed gas system

The pressure in your system may be a result of the availability and demand for compressed gas. The effects of pressure equalization depend on the quantity of compressed gas produced and the amount of compressed gas used. The only common explanation for low during a compressed gas system is just too high a gas demand and insufficient gas production.

Air Compressor Cleaning Instructions

Like other sorts of equipment and machinery, the periodic cleaning and maintenance of the compressor help to make sure the standard of the machine prolongs its life and limits the damage. Not only that, but this also helps to market the excellent working ability of the device. So, how should the compressor maintenance process be done? How’s the time? Why perform compressor maintenance? Is compressor maintenance necessary? Question of the many users. The answer is yes. 

Help the compressor operate and operate stably

Inflatable pumps, especially and every one general machinery after a period of use, will be hard to avoid wearing and rusting parts, details, and components inside the machine. That reduces the working capacity.

Not only that, but they also cause a loose condition for several parts, causing many machine parts to be within the wrong position when there’s a vibration, affecting the operation of the machine.

In particular, the long operation of the compressor without cleaning will cause tons of dirt to be attached, making the operating performance less effective. Dirt can clog the filter, affecting the air quality because of the compressor’s working capacity.

Therefore, periodic maintenance and cleaning and adjustment of deviations will make sure the highest working efficiency, contributing to prolonging the lifetime of the present compressor.

Preventing incidents from arising

Regular maintenance and inspection of the machine will help users quickly detect damaged conditions and deviations of the device. Since then, there are measures to unravel and overcome promptly and within the most timely manner, ensuring that the machine doesn’t occur more severe damage.

Save on repair costs

Air compressors, if not maintained regularly, will quickly reduce their service life. They are explicitly operating with high noise, shaking when working, especially consuming an excessive amount of power. Significantly, suppose abnormal signs are detected early and handled promptly. In that case, it’ll not affect the work progress, and at an equivalent time, help the equipment operate well without significant damage, saving repair costs. , replace components.

We will see that the upkeep, inspection, and cleaning of the compressor is essential and wishes to have strictly adhered to the above reasons. Therefore, you ought to build yourself a simple process of operating and maintaining air compressors.

Air compressor maintenance schedule and time

Users got to perform this work periodically by day, by week, by month, by quarter, etc., so that the machine is often operated smoothly and stably.

  1. Daily machine maintenance

Taking the initiative to require care of and maintain the mini compressor a day is elementary but very effective. Users should perform a drain valve at the rock bottom of the gasoline tank to avoid standing water within the tank. Ideally, about 20-30 minutes, you ought to open the valve one time, whenever from 5 to 10 seconds.

  1. Weekly maintenance

For the upkeep process of commercial air compressors, to avoid disrupting production activities, you ought to perform at the weekend with the subsequent tasks:

– Clean the air cleaner when it’s dirty, prevent blockages that damage the machine, also as reduce operating efficiency.

– Clean the surface of the machine, check the motorcycle for any abnormalities for timely handling.

  1. Monthly maintenance

For oil-immersed screw compressors, users checked the quantity of oil to exchange and maintain oil-free air compressors. You’ll not need to worry about this problem.

Instead, you would like to see the drain valve and valve wire for any problems, check the strain of the wire, tighten bolts, screws,… and follow the instructions for using the compressor appropriately. The manufacturer recommends gas.

The maintenance process for industrial air compressors

  1. Cleaning for the air cleaner 

Ensuring the cleanliness of the air purifier is extremely important because this part is usually clogged with dirt. If not cleaned, it’ll cause an obstacle to the air inlet, affecting the power to work off the machine.

Cleaning the compressor is administered as follows: remove the air cleaner element, use low compressed gas to wash the surface and inside the filter. Blowing should be done from top to bottom. When the machine has been operating for about 2000, you ought to proceed to exchange the filter.

  • Cleaning the air cleaner of the air compressor:

The air machine will charge more slowly if the air cleaner has accumulated an excessive amount of dirt, causing a blockage. Most piston compressors have an easy air cleaner, which is sort of easy to wash and replace.

Remove the filter from the compressor by screwing the thread.

Open the filter and clean the within, removing dirt and foreign objects (if any). Compressed gas is often wont to blow the dust, but avoid using an excessive amount of air, which may cause damage to the filter layers.

Assemble the filter entirely and screw it back onto the compressor head.

If the filter is just too degraded, buy and replace it with a 100% new filter.

  1. Clean the oil cooler of the compressor 

To make sure adequate lubrication and good cooling for the compressor, it’s required that users concentrate on the oil cooler’s cleanliness.

Periodic cleaning for this part is essential to assist the device work on its best. You’ll remove the more remarkable to wash the dust by using compressed gas to spray dust or perform a chemical cleaning.

  1. Perform cylinder maintenance for piston compressors

For piston compressors, the cylinder part plays a crucial role within the air compression process. The piston must go up and down constantly, so it wears out very quickly. If not regularly maintained, increased friction is damaged, affecting working efficiency.

To maintain this part, the user removes the cylinder and cleans the cylinder. At an equivalent time, replaces the new rubber gasket to make sure the most straightforward working efficiency. After completion, you reinstall the cylinder assembly for the device.

  1. Perform filter replacement for compressor 

The filter plays a significant role in ensuring the standard of lubrication for the compressor head, thereby helping the compressor perform its functions and functions well.

Dirty compressor oil will cause the screw to wear, increase friction, cause a significant decline within the compressor’s performance, which cannot guarantee working efficiency.

The car care of the compressor is completed after about 500 – 1000 hours of running. If the machine operates regularly and continuously, this point is often shortened.

During car care, users should pay special attention to the subsequent issues:

– It’s recommended to use special oil for air compressors.

– To avoid severe damage, users got to take care, absolutely don’t use hydraulic oil for the compressor head.

  • Changing the oil is easy. Here are the steps:

Before beginning to change the oil, run the engine for a couple of minutes to warm up the oil and reduce the viscosity, making it easier to empty the oil chamber.

Remove the oil drain screw, and drain the oil until the oil stops flowing altogether. Tighten the oil drain screw back in situ. In large air compressors serving critical compressed gas systems, technicians removed the old oil drain screw and replaced it with a 100% new one.

Unscrew the cap on the highest of the oil chamber, and slowly add new oil into the section. With some compressors with a bit of inlet valve, fill the oil intermittently: pour a touch, stop, then run a touch more.

When the oil reaches the specified level, stop filling and shut the oil chamber cover. Most air compressors require a typical oil level of 2/3 of the oil gauge. Some machines may differ; ask the manufacturer’s specific instructions.

Replace old belts

Sufficient belt tension is a crucial component for the compressor to work at its rated capacity. Most piston compressors have an exposed belt, protected by a mesh cage. With this design, belt replacement is comparatively easy.

Remove the protective cage, usually very simple, by tightening the screws securing the cage.

Once the belt is fully exposed, inspect whether replacement is essential. If the wire has too many cracks, tears, or overlaps, then advance to a subsequent step.

To remove the old belt from the system, hold the strap firmly and stretch on the flywheel side while turning the wheel touch, and therefore, the belt will begin the procedure.

Prepare a replacement belt, pre-install one end of the pulley. Stretch the opposite end over the flywheel and switch the wheel within the other way, and therefore the belt will entirely fit into the system.

Check gas filling time

When installing a replacement machine, proactively measure the filling time from empty to 100% complete at the machine’s standard maximum pressure. Record the measured number as typical.

You can then periodically re-measure this interval throughout the lifetime of the machine. If the charging time is far longer than the quality number, then there’s a drag with the device. You’ll check and maintain by yourself consistent with the above steps or request support from the machine supplier.

Instructions for cleaning the surface of the compressor 

Air compressors will continuously generate heat during operation, and therefore the compressor head usually has fins to beat this problem. 2-stage air compressors typically have a cooling chamber for air before performing the second compression…

Suppose the compressor head and heatsink are heavily dusted. In that case, air contact will be reduced, and warmth dissipation will be significantly reduced, resulting in the danger of shortening the compressor’s lifetime and, therefore, the compressor.

Regularly remove the layers of dirt on the body and, therefore, the compressor head. Pay special attention to the heatsink area and consequently the heatsink cavity of the compressor.

Some Notes When Using A Compressor

– Place the machine during a dry area. Space should have a ventilation and cooling system. Don’t leave the device near a source of warmth, flammable or explosive substances.

– When moving, the machine should release all pressure to make sure safety.

– Don’t spray high-pressure air into sensitive areas like eyes, lungs, nose, etc. High atmospheric pressure is often dangerous.

– It’s necessary to settle on the proper sort of grease to ensure the machine’s specified performance and speed.

– If changing the oil, users concentrated on the machine to prevent working for about 15-20 minutes before performing the car care job.

– Don’t pour oil beyond the limit, nor let the machine operation when the oil level is just too low.

– Concentrate on the machine parts such as air cleaner, filter valve, filter, oil separator, pressure regulating valve, etc.


Nowadays, everyone knows the importance of air compressors in any industry. But to own a good machine is not easy. Check out the details here!

A good compressed air system also needs to ensure the cooling requirements to ensure stable operation of the equipment, less unexpected problems.

The cooling part of the machine must be of stable quality to help maintain high working efficiency, increase the life of the device and help ensure safety, and reduce the risks arising from the problem of temperature rise…

With small air compressors, it is easy to operate, large-sized compressors must know how to use them, so when choosing a machine, it is necessary to pay attention and choose the right type.
