Screw air compressor failure analysis

The analysis of the cause of the failure and the solution are as follows: (1) Whether the condensed water discharged from the trap has a large oil content, if so, check the leakage point in the unit and eliminate it, check whether the oil level of the compressor is too high, if so, reduce the oil level; (2 ) Whether the opening pressure of the minimum pressure valve is normal, if so, troubleshoot, and it is necessary to replace the valve; check whether the oil return pipe is blocked, if so, clean or replace the oil return pipe: (3) Replace the oil separator core.
