Try to turn the compressor by hand. It should be possible to turn it around. It should turn around smoothly, without any 'hickups' (be sure to completely shut down the air compressor!). Check the isolation of the motor windings.
[pdf] Check whether the oil content in the condensate discharged from the drain valve of the Kaishan air compressor is too high, whether the oil level of the compressor is too high, whether the opening pressure of the small pressure valve is normal, whether the return oil pipe is blocked, and whether the oil separation core is blocked.
[pdf] Addressing high temperature failures in screw air compressors requires a proactive approach, including regular maintenance, quick repairs, improved environmental conditions, and optimized operating parameters.
