Slurry pumps are centrifugal pumps that transport slurry rich in media particles and are widely used in various industries. When transporting slurry containing media particles, it has advantages that other pumps cannot replace. However, even with the unique advantages of slurry pumps, there are still some failure problems.

Some Common Problems and Solutions when Using Slurry Pumps

Slurry pumps are centrifugal pumps that transport slurry rich in media particles and are widely used in various industries. When transporting slurry containing media particles, it has advantages that other pumps cannot replace. However, even with the unique advantages of slurry pumps, there are still some failure problems.

1. The slurry pump cannot be started

Solution: First, check the power supply: whether the connector connection is secure; whether the switch contact is tight; whether the fuse is blown; whether the three-phase power supply is equal. If there is an open circuit, poor contact, blown fuse or phase loss, the cause should be identified and repaired in time. Secondly, check whether it is a mechanical failure of the water pump itself.

Common reasons: the packing is too tight or the impeller and the pump body are blocked by debris; the pump shaft bearing and leakage reducing ring are rusted; the pump shaft is severely bent, etc.

Troubleshooting methods: loosen the packing and clear the water diversion channel: disassemble the pump body to remove debris and rust; remove the pump shaft and correct it or replace it with a new one.

2. The slurry pump does not rotate

If the solid sediment inside the volute is blocked, measures can be taken to remove the blockage.

3. Insufficient flow of slurry pump

If the impeller or the inlet and outlet pipes are leaking, you can clean the impeller or the pipes. If the impeller is leaking and heavy, you should replace it. If there is air leakage at the material port, the power speed of the pressure-sensitive vertical material slurry pump does not match or the belt slips. The speed is low; the installation angle of the axial flow pump blades is too small: the lift is insufficient, the pipeline is too long or the pipeline has a right-angle bend: the suction lift is high; the bottom valve, pipeline and impeller are partially blocked or the impeller is missing: the outlet pipe If the water leakage is serious, troubleshooting methods: restore the rated speed, remove the grease on the belt, adjust the belt tightness, adjust the blade angle, lower the installation position of the water pump, shorten the pipeline or change the curvature of the pipeline; seal the leakage of the water pump and tighten it Filling: clear the blockage, replace the impeller; replace the leakage reduction ring, block the leakage.
