The air compressor has 4 important maintenance cycles, which greatly expands the life of the machine.

The air compressor is a relatively complicated apparatus, so its maintenance is more stringent. Generally divided into 4 stages: daily maintenance, monthly maintenance, quarterly maintenance, annual maintenance.

1、daily maintenance

Check the oil level, check the air filter and coolant level, check the hose and all the pipe joints for leaks, check that the consumables have reached the replacement cycle, must be stopped to replace, check the host exhaust temperature, reach or approach the warning temperature, The oil cooler must be cleaned to check the differential pressure of the separator. When the pressure is above 0.6 bar (limit 1 bar) or the pressure difference begins to decrease, stop the separation core and so on.

2、monthly maintenance

Check the cooler, clean it if necessary, check all wire connections and tighten, check the AC contactor contacts, clean the surface of the motor suction port and the surface of the casing, clean the return filter, check the air compressor settings Is it consistent with the operation.

3、quarterly maintenance

Clean the main motor and fan motor, replace the oil filter, clean the cooler, check the minimum pressure valve, safety valve, and check the sensor.

4、annual maintenance

Replace the oil and oil separator filter element, replace the air filter element, oil filter, safety valve calibration, check the flexible coupling, check the cooling fan, clean the automatic drain valve, and replenish or replace the motor grease.

The daily maintenance and maintenance records of the screw air compressor can be recorded periodically or irregularly, or recorded after maintenance. Accurate records facilitate timely analysis and troubleshooting of air compressor failures. The main contents of the maintenance record are inspection, cleaning, adjustment, replenishment, replacement and corresponding time.
