Air compressor maintenance, why must the air compressor be switched regularly? When multiple air compressors are operated in parallel, they must be switched regularly. For an air compressor with a humid working environment, switching operation is beneficial to discharge the moisture in the lubricating oil; if the air compressor is out of service for a long time (such as about a month), it will cause the adhesion particles on the oil filter element or the oil fine separator to dry out , Blocking the filter hole of the oil filter element or the oil fine separator fiber, shortening the service life of the filter element; the upper part of the air compressor rotor is not soaked in lubricating oil, and it will be shut down for a long time, which will cause this part of the rotor to contact with moist air and cause corrosion; Shutdown will also cause grease deposits on the air compressor pipeline or main engine, which will force the air compressor to be overhauled.

What items should be checked before the screw air compressor starts?
(1) Confirm that the power supply is input and the indicator light is on.
(2) Open the oil-gas drum drain valve, and close it after draining the condensate from the lower part of the gas drum.
(3) Keep the oil level above the lowest oil level line.
(4) The outlet door of the air compressor is opened.
(5) Whether there is air leakage, oil leakage or water leakage at each connection part.

What should be paid attention to in the operation of screw air compressor?
(1) If there is abnormal sound or abnormal vibration during operation, stop immediately.
(2) There is pressure in the running pipeline. Do not loosen the pipe bolts and open unnecessary valves, such as traps and drain valves.
(3) Check whether the automatic steam trap is operating normally, otherwise water will be brought into the system.
(4) The oil and gas barrels should be drained and watered once a week. The unit should not be inactive for a long time, and it should be turned on for at least 2 hours a week.
(5) All doors of the soundproof enclosure must be closed during operation.

What is the hazard of the leakage of the outlet check door of the screw air compressor? After the air compressor is stopped, the outlet check door is not closed tightly, which will cause the compressed air in the system to enter the air compressor system that is out of service, and the leakage will keep the system in the system. At a certain pressure, the discharge solenoid valve has been exhausted at this time, and the oil contained in the exhaust will cover the inlet air filter element, thereby reducing the service life of the air filter element.

Air compressor maintenance The check door is not closed tightly so that the air compressor shaft sealing ring is compressed and deformed for a long time, and even the lip of the sealing ring is damaged, causing the oil seal to leak. The normal oil level may not be displayed due to the pressure in the oil and gas barrel
