8 Things To Do When Your Air Compressor Won’t Build Enough Pressure

Reciprocating Air Compressor

The industrial air compressors work with pressure to perform the desired function. When the compressor fails to build the required pressure for the process, the whole cycle disturbs and we don’t get the desired output. 

According to industrial compressor manufacturers, insufficient pressure can make the compressor work for longer which can lead to heating and shutdown. To prevent such a situation, it is important to learn a few things that will help you when your compressor will not build enough pressure. 

Clean the filters 

First of all, inspect the air inlet filters. The filters can get accumulated with debris and other kinds of buildup during processing. Clean the filters well if they are not clean already. Don’t wait for the compressor to slow down to clean the filters. Make sure to schedule a filter cleanup over regular periods. 

Perform a pump up test 

The right way to see how much time your compressor is taking to build pressure is performing a pump up test. Here is how you can perform it: 

Empty the air tank and close the discharge service valve. Start from 0 and record the time the compressor takes to reach the required PSI.

If you are confused about the maximum pressure and other terms, contact your distributor for better understanding. 

Check for leaks and air demands 

The most annoying problem is a leaking system. Most of the systems lose pressure due to leaks and that’s a never ending issue. Inspect the tank really well and it is time for replacement if you find any leaks. 

Also, make sure the air demand settings are on point. 

Examine all the system valves 

Valves can be a serious culprit if not handled well. Make sure the inlet valve is working fine and opens when required. Also, check if the drain valve is properly closed or not. Sometimes a loose valve can be the real problem. 

Check all the valves such as safety valves and make sure all of them are working fine and there is no leakage. Check for oil lubrication and make sure there is no buildup. 

Inspect belt condition 

Disconnect the power and turn of the machine to start inspecting the belt condition. Get rid of the belt guard and start working on the bolts. You can replace or tighten the belt as per requirement. Read the manufacturer guidelines really well to perform any replacement. Tighten the bolts and set up the belt guard again.

Check pump rings  

Worn out pump rings can reduce the pressure buildup and make the air leak through the system. It can also lead to excess oil transmission. Check the pump rings and see if they need replacement. Get done with it as soon as possible if it happens to be the issue. 

Examine motor capacitors 

Malfunctioning capacitors mean the machine is not getting enough power supply to function properly. Examine them yourself or hire a professional if you don’t know how to inspect and replace them. 

Inspect the Air/Oil separator 

The compressors that use oil as lubricant have oil separators to prevent excess mixing of oil with air. If the air/oil separator is not clean and has buildup and clogging, it can lead to poor performance of the machine. Poorly functioning machine fails to reach the desired pressure and you end up with increased costs. Make sure everything is cleaned well on time. 

These were a few things that can lead to reduced pressure performance of your compressor. The air compressor manufacturers in Ahmedabad suggest scheduling regular servicing for your compressor’s better performance and long life.
