Screw pump is a rotary pump that relies on the volume change and movement of the meshing space formed by the pump body and screw to transport liquids or increase their pressure. Screw pumps are divided into single screw pumps, twin-screw pumps, and triple screw pumps according to the number of screws.
Classified by the number of screws
Single screw pump - a pump in which a single screw engages and rotates in the internal thread groove of the pump body.
Twin screw pump - a pump that transports liquid by interlocking two screws.
Multi screw pump - a pump that transports liquid by interlocking multiple screws
Screw pump - common problem handling
1. Severe vibration or noise generated by the pump body:
Cause: Poor installation of water pump or high installation of water pump; Motor ball bearings are damaged; The main shaft of the water pump is bent or not concentric or parallel with the main shaft of the motor.
Solution: Install the water pump steadily or lower the installation height of the water pump; Replace the motor ball bearings; Correct the bent water pump spindle or adjust the relative position between the water pump and the motor.
2. Overheating of transmission shaft or motor bearings:
Causes: Lack of lubricating oil or bearing rupture, etc.
Solution: Add lubricating oil or replace bearings.
3. The water pump does not produce water:
Cause: The pump body and suction pipe are not fully filled with water; The dynamic water level is lower than the water pump filter pipe; Broken suction pipe, etc.
Solution: Fill the pump body and suction pipe with water for diversion; Raise the dynamic water level or lower the water pump filter pipe; Replace the suction pipe, etc.
