Heavy Duty Sand Processing Slurry Pump

Five advantages of heavy duty sand processing slurry pump

1. The slurry pump has high working efficiency, reasonable design of lubrication and cooling system, and low operating temperature.

2. The overflow parts of the slurry pump are wear-resistant, have a long service life, require less maintenance, and save production costs.

3. The bearing box of the slurry pump has a reasonable layout, good sealing, and the fluid is not easy to leak.

4. The design of the overflow parts of the slurry pump is reasonable, the disassembly is convenient, energy saving and consumption reduction.

5. The slurry pump runs smoothly, with small vibration, wide flow passage and large flow adjustment range.

Common faults and solutions of heavy duty sand processing slurry pumps

1. The slurry pump cannot be started

Common reasons: the packing is too tight, the impeller is stuck by debris; the pump shaft and bearing are embroidered; the pump shaft is bent.

Solution: Check the power supply first, then loosen the packing and loosen the water diversion tank; disassemble to clean up debris and rust; correct the pump shaft.

2. The heavy duty sand processing slurry pump does not absorb water

Common reasons: there is air in the pump, intake of the suction piping system, intake of the shaft seal.

Solution: Add some exhaust measures, increase the sealing, and ensure the water volume and water pressure at the shaft seal.

3. Bearing overheating

Common reasons: the motor shaft and the pump shaft are not concentric, the elastic pad of the coupling is damaged, the oil is not clean, or the oil chamber enters the slurry.

Solution: Adjust the concentricity of the motor shaft and the pump shaft, replace the elastic pad, change the new oil and prevent the oil chamber from entering the slurry.

4. Vibration and noise

Common causes: Bearing damage, pump evacuation due to insufficient slurry supply, blockage of suction line or impeller.

Solution: Check and replace the bearing, increase the slurry supply or close the outlet valve of the slurry pump, and adjust the characteristics of the pump to match the characteristics of the pipeline.

5. Motor overheating

Common reasons: the voltage is too high or low, the motor is overloaded for a long time, and the motor connection is wrong.

Solution: adjust the voltage, limit the number of starts, select the thermal protection correctly, use the motor according to the upper-scale rating of the motor, and check the connection of the motor.

The use of the slurry pump cannot wait for a fault to be repaired, and attention must be paid to maintenance during normal installation and use. For example, when replacing bearings, you must use regular products and ensure that there is no dust in the bearing components, ensure that the pump components and pipeline systems are installed correctly and smoothly, and adjust the tightness of the packing at any time.
