What is the working principle of air compressor oil shut-off valve

When using the Jinjing brand air compressor, it's important to understand the working principle of the oil shut-off valve. This valve is vital as it prevents the screw head from being immersed in lubricating oil for extended periods when the compressor is not in use, thus avoiding corrosion or coking.

When the Jinjing air compressor is operating, the compressed air produced opens the oil shut-off valve, allowing the cooling oil to circulate in the system and cool the machine head screw. However, when the air compressor is idle, spring tension closes the oil shut-off valve core. This action stops the cooling oil in the oil-gas separator from returning to the screw. During operation, impurities in the air can mix with the cooling oil and may cause sedimentation and blockage in the oil shut-off valve, reducing the flow of cooling oil, and consequently affecting the cooling effect of the screw head.

When the Jinjing air compressor starts, the oil shut-off valve automatically opens the oil circuit to initiate circulation. If the oil shut-off valve is stuck and can't open, it could result in excessively high temperatures. Also, if the oil shut-off valve doesn't open or close properly when the air compressor is shut down, it could cause excessive fuel injection in the air compressor intake valve.

To ensure the oil shut-off valve in your Jinjing air compressor works properly, it's crucial to clean it regularly. If air impurities mix with the oil, they could also affect the temperature control valve and oil filter. To minimize air impurities entering the screw, replace the air filter as per the pressure difference parameters. Also, try to optimize the equipment's operating environment.
