How to maintain an Air Compressor?
For an air reciprocating compressor to operate smoothly and safely, it must be properly maintained. Without proper maintenance, compressors can stop working and pose a risk to your safety. Properly maintaining an air compressor is essential if you own one.
Safety valve
As the tank pressure exceeds the preset upper limit, the pop-off valve, also called a safety valve, automatically releases air from the tank. It prevents the tank from bursting due to excessive pressure. By pulling the safety valve until it pops back into place, you have to check it weekly to ensure that it is functioning properly. It must discharge air from the tank at all times and return at roughly 40-50 PSI. If it fails to do so, it must be replaced.
Oil Change
The oil level should not fall below the red circle or dot on the oil level sight glass. You should change the oil every 500 hours or once a month. To change the oil, you must:
- Allow the oil to warm up by running the device for a few minutes.
- Unplug the device.
- Place a container beneath the pump's end.
- Allow the oil to gather in the container after removing the oil drain stopper.
- Change the drain stopper.
- Replace the oil in the crankcase.
Filter
Every air compressor has an air filter mounted on the intake. If yours does not, you will need to install one. The air filter must be checked on a regular basis. Remove the air filter housing cover to accomplish this. A dirty filter must be replaced to ensure that the unit operates properly. Clogged air filters contribute to the compressor's low suction and efficiency.
Drain the tank
It is common for customers to forget to drain the tank after using the machine. The result can be corrosion in the tank. Always drain moisture from the tank by opening the drain valve at the tank's bottom. The longer the air receiver sits without draining, the less effective air storage capacity it has, and it can considerably shorten its life.
Cleaning
Keep your air compressor clean at all times. Clean the trash from the motor, flywheel, tank, airlines, and pump cooling fins. Most compressors are air cooled, and any dust or other deposits may prevent effective heat transfer from the compressor to the surrounding environment, resulting in higher operating temperatures. All of this must be done when the unit is turned off.
Pressure switch
Make sure your pressure switch is still operating within its specified range. Over time, low-quality pressure switches become less precise. Note the pressure on the tank's pressure dial or gauge when the compressor stops, then release the air from the tank and note the pressure when the compressor begins. Compare them to the manufacturer's settings and, if necessary, contact a compressor service mechanic to recalibrate.
Storage
Keep the air compressor in a cool, dry place when not in use. Remove all moisture from the tank. All oil must be emptied from the crankcase. All of the pipes should be disconnected and hung with the open ends down to drain moisture.
