6 FAQs about [Oil injection during screw air compressor failure]

How lubricating oil is injected into a compressor?

Simultaneously, lubricating oil is injected into the compression chamber to lubricate, seal, and cool. The compressed oil-air mixture is separated by an oil-gas separator, with pure compressed air exiting through the exhaust port and the lubricating oil being filtered, cooled, and recycled.

What happens if a screw air compressor malfunctions?

Therefore, any malfunction in a screw air compressor not only disrupts production rhythms but may also lead to safety issues and economic losses. Thus, an in-depth study of common faults and their solutions is crucial for ensuring the stability and efficiency of industrial production.

Why do screw compressors fail?

Due to limitations in rotor stiffness and bearing life, screw compressors can only be used in medium and low-pressure ranges. Failure cause analysis: (1) The pressure on the pipeline exceeds the rated load pressure, and the pressure regulator is disconnected.

What happens if a compressor cartridge is saturated?

When the cartridge is saturated, it loses its ability to effectively separate oil from the compressed air, leading to oil carryover. Therefore, maintaining the correct oil level is imperative. Over time, as the compressor operates, oil particles accumulate within the separator cartridge.

Why is my air compressor not working?

Analysis of the cause of the failure: The environment in the computer room is poor, and the air contains a lot of dust. During operation, the air compressor frequently suffers from oil deterioration, filter clogging, and other faults, the oil change cycle is shortened, and the operation and maintenance cost is greatly increased.

What happens if compressor oil is vaporized?

As a result, more oil may carry over into the compressed air, leading to contamination. High temperatures can promote the vaporization of compressor oil, causing it to become more volatile. Vaporized oil can mix with the compressed air, forming a mist or aerosol that is more difficult for the separator cartridge to capture and remove.
