Third, the operation of the screw pump
If the screw pump in the work of noise, which is often due to oil temperature is too low, the oil viscosity is too high, the oil into the air, the coupling lost or excessive wear and tear caused by the pump.
1.2 Listen to abnormal noise and vibration.
1, the daily maintenance and maintenance 1.1 in the screw pump to check the gear box when the oil level.
The shaft seal should allow a slight amount of leakage, such as leakage does not exceed 20-30 seconds / drop, it is normal.
Pump work, should pay attention to check the pressure, temperature and mechanical shaft seal work.
