A common type of screw air compressor filter, screw air compressor filter failure will affect its service life and the personal safety of the operator, so in industrial production, to understand the screw air compressor failure is very important.
1.Screw air compressor filter failure phenomenon: the unit fuel consumption or compressed air oil content is large
Reason: the cooling dose is too much, the correct position should be observed when the unit is loaded, and the oil level should not be higher than half at this time; The blockage of the return pipe will also cause the failure of the screw air compressor; The installation of the return pipe does not meet the requirements will cause the screw air compressor to consume too much oil; The exhaust pressure is too low when the unit is running; Oil separation core rupture will lead to screw compressor failure; The separator inside the cylinder is damaged; Coolant deterioration or overdue use.
2.Screw air compressor failure phenomenon: low unit pressure
Reason: the actual gas consumption is greater than the output gas of the unit; Screw air compressor vent, intake valve failure (loading can not be closed); The transmission system is not normal, the ambient temperature is too high, and the air filter is blocked; Load solenoid valve (1SV) failure; Minimum pressure valve stuck; There is a leak in the user network; 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 leakage;
3.Screw type air compressor fault phenomenon: fan motor overload
Cause: Fan deformation; Fan motor failure; Fan motor thermal relay failure (aging); The wiring is loose; The cooler is blocked; High exhaust resistance.
4.Screw air compressor failure phenomenon: the unit current is large
Reason: the voltage is too low; The wiring is loose; The unit pressure exceeds the rated pressure; The oil separation core is blocked; Contactor failure; Host failure; Main motor failure.
