Failure Test Of Screw Air Compressor

1. Screw air compressor fault phenomenon: the unit has large fuel consumption or large compressed air oil content
The reason for this failure is that due to too much cooling cold filling, the correct position should be observed when the unit is loaded, and the oil level should not be higher than half; Blockage of the return oil pipe will also cause screw air compressor failure;
The installation of the return oil pipe does not meet the requirements, which will cause excessive fuel consumption of the screw air compressor; The exhaust pressure is too low when the unit is running; The rupture of the oil separation core will cause the screw air compressor to fail; damage to the internal partition of the separation cylinder; The coolant has deteriorated or expired.
2. Screw air compressor fault phenomenon: low unit pressure
The reason for this failure is that the actual gas consumption is greater than the output gas volume of the unit; Screw air compressor degassing, intake valve failure (cannot be closed when loading); The transmission system is abnormal, the ambient temperature is too high, and the air filter is blocked; load solenoid valve (1SV) failure; The minimum pressure valve is stuck; There is a leak in the user pipe network; Screw air compressor failure such as pressure sensor, pressure gauge, pressure switch, etc. will lead to low pressure of the unit; Leakage of the pressure sensor or pressure gauge input hose;
3. Screw air compressor fault phenomenon: fan motor overload
fan deformation; fan motor failure; fan motor thermal relay failure (aging); loose wiring; clogged radiator; High exhaust resistance.
4. Screw air compressor fault phenomenon: the unit current is large
The voltage is too low; loose wiring; The unit pressure exceeds the rated pressure; clogged oil separation core; contactor failure; Host failure; failure of the main motor;
