Slurry Pump Troubleshooting

Released on Jul. 23, 2018

We will inevitably have some troubles in the process of using the Vertical Sump Slurry Pump. Below, the Vertical Long Shaft Pump Supplier will introduce the common faults and treatment methods, and hope to help the family.

1. Folding pump vibration

Cause: The pump shaft is not concentric with the diesel engine (or motor), the impeller is unbalanced, and the bearing is damaged;

Solution: Adjust the concentricity, the impeller for balance test, and replace the bearing.

2. Fold the pump on the water slowly

Reason: The gap between the front liner and the impeller is large, and the outlet pipe cannot seal the air and is empty;

Solution: Adjust the gap, adjust the water outlet pipe, and install the vacuum pump.

3. Folding pump does not absorb water

Reason: insufficient water infusion, air in the pump can not be discharged, air leakage in the suction pipe, and large gap between the front liner and the impeller;

The original solution: continue to inject water, check the pipeline for air leakage, adjust the gap between the impeller and the front liner.

4 folding water pressure

Low pressure and small flow

Cause: There is air in the pump, the gap between the impeller and the front lining plate is large, the clutch is not closed tightly, and the impeller or lining plate is worn;

Solution: Drain the gas inside the pump, adjust the gap to adjust the friction plate gap of the clutch, and replace the impeller or liner.

5. Folding pump wears fast

Reason: The construction environment (large particles) is poor, the transportation distance is long, and the water inlet pipeline is long;

Solution: Replace the sand field, add afterburner unit, shorten the length of the inlet pipe to reduce cavitation.

6 impeller journal wear fast

Reason: The high pressure pump has a low lift, the packing is misaligned, and the pump shaft and the back cover are not concentric;

Solution: Replace the high pressure pump above the lift of the mud pump, replace the packing, and adjust the concentricity.
