Why does the slurry pump have noise and solutions?
1. Cavitation phenomenon: Most of the reasons for the noise of the slurry pump in the newly installed slurry pump products are installation problems. For example, the import and export pipelines are not installed according to the standard diameter of the pump, but the diameter of the pipeline is increased, resulting in the appearance of the slurry pump.

For example, the import and export pipelines are not installed according to the standard diameter of the pump, but the diameter of the pipeline is increased, resulting in the appearance of the slurry pump. The phenomenon of cavitation has a large vibration of the slurry pump and the phenomenon of noise in the slurry pump. It can be solved by closing the outlet valve or changing the diameter of the pipeline.
2. Rotor imbalance: The rotor of the slurry pump or the rotor of the driver is unbalanced, and the rotor should be rebalanced in this case.
3. Correction coupling: The slurry pump with coupling is included in the horizontal multi-stage slurry pump. Due to the poor alignment of the pump shaft and the motor shaft, mechanical vibration and noise occur. The solution is to recalibrate the coupling. Shaft device.
4. Serious bearing wear: The bearing wear is too serious, resulting in excessive clearance, and a new bearing should be replaced.
5. Loose anchor bolts: Caused by loose anchor bolts or weak foundations, check and tighten loose parts or replace them.
6. The liquid level is lower than the pump: for example, the user chooses the horizontal slurry pump product and the liquid level is lower than the pump during installation. The inlet pipeline does not have a bottom valve installed, resulting in the phenomenon of evacuation of the horizontal slurry pump. In this case, the bottom valve tank should be installed. Start the pump after diverting water, or it is more appropriate to use a self-priming slurry pump instead.
7. Loose slurry pump parts: Long-term work causes loose or damaged slurry pump parts, fasten loose parts or replace them.
8. Support the pipeline by the slurry pump: the bracket is not firm or the pipeline is supported by the pump to cause pipeline vibration. The solution is to reinforce the pipeline bracket, and should not rely on the pump to support the pipeline.
9. There are metal objects in the slurry pump: metal objects or other objects enter the pump, or there is friction between the impeller and the pump shell. The solution is to disassemble the pump body for inspection to eliminate friction.
