Ingersoll Rand air compressor maintenance, why air compressors must be switched regularly? When multiple air compressors are running in parallel, they must be switched regularly. For the air compressor with a humid working environment, the switching operation is beneficial to discharge the moisture in the lubricating oil; if the air compressor is stopped for a long time (such as about one month), the adhered particles on the oil filter or the oil separator will be dry. Blocking the filter hole of the oil filter or oil fine separator fiber, shortening the service life of the filter element; the upper part of the rotor of the air compressor is not immersed in lubricating oil, and the machine is stopped for a long time, so that the rotor is in contact with humid air and rust occurs; The shutdown will also cause oil deposits on the air compressor pipe or the main unit, which will force the air compressor to be repaired.

What items should I check before starting the screw air compressor?

(1) Confirm that the power is supplied and the indicator is on.

(2) Open the oil and gas barrel drain valve, and then close the condensate water in the lower part of the helium gas cylinder before closing.

(3) The oil level is kept above the oil level.

(4) The air compressor exit door is open.

(5) Whether there is air leakage, oil leakage or water leakage at each joint.

What should be paid attention to when operating the screw air compressor?

(1) When there is abnormal sound and abnormal vibration during operation, stop immediately.

(2) There is pressure in the running pipeline. Do not loosen the pipeline bolt plug and open unnecessary valves, such as traps and drain valves.

(3) Always check that the automatic steam trap is functioning properly, otherwise moisture will be carried into the system.

(4) Oil and gas barrels should be drained and water once a week. The unit can't run for a long time, and it will be turned on for at least 2 hours every week.

(5) All soundproof enclosure doors must be closed during operation.

What is the hazard of the leakage of the screw air compressor at the exit of the check valve? After the air compressor is stopped, the exit check valve is not closed tightly, which will cause the pressurized air in the system to enter the air compressor system that is out of service. The leakage will keep the system in place. At a certain pressure, the bleeder solenoid valve is always vented, and the oil contained in the venting gas is applied to the inlet air filter to reduce the service life of the air filter.

The Ingersoll Rand air compressor maintenance backstop door is not tight enough to cause the air compressor shaft seal to be deformed under pressure for a long time, and even damage the seal ring lip, causing the oil seal seal to leak. Oil tanks may also be unable to display normal oil levels due to pressure.
