Tell us the fault inspection method of screw air compressor

What are the methods for fault inspection of screw air compressor? Let's have a brief understanding with Baoman.

1. Fault condition of screw air compressor: large oil consumption of the unit or high oil content of air compression

The reason for this failure is that there is too much refrigeration used. The proper part should be observed when the unit is loaded. At this time, the oil volume should not be more than half; Blockage of the return oil pipe will also lead to failure of the screw air compressor; The assembly of the return oil pipe does not meet the requirements, which will lead to excessive oil consumption of the screw air compressor; The working pressure of the exhaust pipe is too low during the operation of the unit; The core crack caused by oil separation will cause screw air compressor failure; The internal baffle of the separated cylinder section is damaged; The coolant is moldy or overdue.

2. Fault condition of screw air compressor: low working pressure of the unit

The cause of this fault is that the specific air supply exceeds the output air supply of the unit; Discharge air from screw air compressor Bypass valve failure (cannot be closed during loading); The transmission device is abnormal, the operating temperature is too high, and the air filter element is blocked; Fault of load vacuum solenoid valve (1SV); Z low pressure valve stuck; Leakage of the customer's pipeline network; Failure of screw air compressor such as liquid level sensor, barometer and pressure controller will cause low working pressure of the unit; The liquid level sensor or barometer key in plastic hose leaks steam.

3. Screw air compressor fault condition: fan motor load

Fan deformation: fan motor failure; Fan motor thermal relay failure (aging); Loose wiring; The cooling tower is blocked; The exhaust system has large friction resistance.
