How many hours air compressor maintenance once

how long does the air compressor need to be maintained?

1.500 hours: when the air compressor runs for 500 hours, the oil filter element and air compressor lubricating oil will be changed for the first time after the new machine is used. Remove the air filter for cleaning and blow it out with low-pressure compressed air. Do not blow air from the outside to the inside to avoid blockage.

2.2000 hours: When the air compressor runs for 2000 hours, check whether the pipe joints, bolts and terminal screws are loose, and tighten them. Replace "three filters and one oil". Check whether all solenoid valves and protection differential pressure switches operate normally.

3.6000 hours: The air compressor runs for 6000 hours, the cooler needs to be checked and cleaned if necessary; check the action and moving parts of the intake valve, and supplement or replace the motor grease. Clean the motor and fan motor, and clean the automatic drain valve. Check the minimum pressure valve and sensor and calibrate the relief valve.

4. When the air compressor runs for 20,000 hours, it is necessary to repair the head of the air compressor, replace the body bearing and oil seal, and adjust the gap. The insulation of the measuring motor should be above 1MΩ
