Methods To Solve Common Problems Of Submersible Slurry Pumps

As a commonly used equipment in the industrial field, submersible slurry pumps often encounter a series of problems during operation.In response to these common problems, we can take the following solutions to ensure the normal operation of the submersible slurry pump and extend its service life.1. Problem of not absorbing sand Reason: 1. There is not enough water injection and the air in the pump cannot be discharged.2. The suction pipe leaks air, causing air to enter the pump body.3. The gap between the front lining plate and the impeller is too large, which affects the suction performance of the pump.Solution: 1. Continue to inject water into the drainage to ensure that the pump body is filled with water and discharge all air.2. Check the water suction pipe to ensure that there are no air leakage points and repair the air leakage areas.3. Adjust the gap between the impeller and the front lining plate to maintain an appropriate distance to improve suction efficiency.2. Small water outlet pressure and small flow rate problems. Reason: 1. There is air in the pump, which affects the flow of water.2. The impeller or lining plate is seriously worn, resulting in a decrease in efficiency.3. The clutch is not closed tightly, causing power transmission loss.Solution: 1. Exhaust the air in the pump to ensure that the pump body is filled with water.2. Replace the worn impeller or lining plate to restore the working efficiency of the pump.3. Adjust the friction plate gap of the clutch to ensure stable power transmission.　　3. Pump internal wear problems Reasons: 1. The construction environment is harsh and the particles in the medium are relatively large.2. The conveying distance is long and the pipeline wear is intensified.3. After long-term operation, the parts will wear naturally.Solution: 1. Improve the construction environment and reduce large particulate matter in the medium.2. Shorten the conveying distance and reduce pipeline wear.3. Regularly check the internal parts of the pump body and replace the worn parts in time.4. Problem of excessive pump temperature Reason: 1. Long-term operation causes the motor to overheat.2. Failure of the sealing structure or improper installation, resulting in heat accumulation.Solution: 1. Strengthen the maintenance of the motor, replace the thermal components in a timely manner and check the connection of the wires.2. Replace or reinstall the seal structure to ensure good sealing effect.5. Problem of excessive pump sound. Reason: 1. The friction between the impeller and the pump body produces noise.2. The collision between the slurry and the casing, impeller and other components produces noise.Solution: 1. Check the status of the impeller and pump body and perform maintenance to reduce friction noise.2. Adjust the looseness between the impeller, shaft, bearing and the base to avoid collision noise.6. Other common problems and solutions 1. Pump import blockage: Clean up imported impurities or hard objects, and adjust imported valves and pipelines.2. The pump outlet flow decreases: Check and clean up the outlet pipeline blockages, and adjust the pipeline layout to avoid vortex.3. Bearing overheating: Check the lubrication condition, replace the damaged bearing, and adjust the unit concentricity.In response to common problems with submersible slurry pumps, we need to conduct detailed inspections and analysis based on actual conditions, and take corresponding solutions to ensure the normal operation of the pump.At the same time, regular maintenance and maintenance are also important means to reduce the occurrence of faults and extend the service life of the pump.
