Failure Analysis of Screw Air Compressor
Screw air compressor is a common type of air compressor. The failure of screw air compressor will affect its service life and personal safety of operators. Therefore, in industrial production, it is very important to understand the failure of screw air compressor. Screw air compressor is a common type of air compressor.

1. Screw air compressor failure phenomenon: the unit has high fuel consumption or compressed air with large oil content
The reason for this failure is that due to too much cooling dose, the correct position should be observed when the unit is loaded. At this time, the oil level should not be higher than half; the oil return pipe blockage will also cause the screw air compressor to malfunction;
If the installation of the return pipe does not meet the requirements, the screw air compressor will consume too much fuel; the exhaust pressure will be too low when the unit is running; the oil separation core will cause the screw air compressor to malfunction; the internal separator of the separation cylinder will be damaged; The agent is degraded or used overdue.
2. Screw air compressor failure 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; the screw air compressor deflate, the intake valve is faulty (cannot be closed when loading); the transmission system is abnormal, the ambient temperature is too high, the air filter is clogged; Solenoid valve (1SV) failure; minimum pressure valve stuck; user pipe network leak; pressure sensor, pressure gauge, pressure switch and other screw air compressor failure will lead to low unit pressure; pressure sensor or pressure gauge input hose leak ;
3. Screw air compressor failure phenomenon: fan motor overload
Fan deformation; fan motor failure; fan motor thermal relay failure (aging); loose wiring; cooler blockage;
4. Screw air compressor failure phenomenon: large unit current
The voltage is too low; the wiring is loose; the unit pressure exceeds the rated pressure; the oil separation core is blocked; the contactor is faulty; the main unit is faulty; the main motor is faulty;
