What are the importance of the application fields of slurry pumps? Below is a brief analysis: Slurry pumps can be used in industries such as mining, power, metallurgy, coal, and environmental protection to transport slurry containing abrasive solid particles. Such as slurry transportation in metallurgical beneficiation plants, hydraulic ash removal in thermal power plants, coal slurry and heavy medium transportation in coal washing plants, dredging of rivers, dredging of rivers, etc. In the chemical industry, some corrosive slurries containing crystals can also be transported.
Currently, 80% of the slurry pumps are used in mining industry beneficiation plants. Due to the relatively poor initial selection conditions of the ore, the service life of the slurry pump is widely low in this section. Of course, different ores have varying degrees of abrasion.
Although the use of slurry pump is ordinary, precise use is very important. Due to the limited nature of its title, slurry pumps have caused misunderstandings among some non professionals. In fact, impurity pumps, dredging pumps, dredging pumps, etc. are all within the scope of slurry pump usage. In the use of slurry pumps, it is important to pay attention to correct design, accurate calculation, and appropriate selection. These points are quite important.
How can we solve the problem of blockage found during use? Many customers consider this to be a complex issue, but if this blockage problem is not handled properly, it can easily cause damage to the equipment, thereby affecting the efficiency of use. Therefore, everyone should pay special attention to it. In fact, by grasping the following points, the problem can be easily solved.
There are various reasons for the noise generated by slurry pumps during operation, and the following are possible causes and solutions:
1. Cavitation phenomenon: The diameter of the inlet and outlet pipes of the slurry pump is not consistent with the standard diameter, resulting in cavitation phenomenon, which causes large vibration and noise of the slurry pump. The solution is to reinstall the inlet and outlet pipelines according to the standard diameter of the pump.
2. Unbalanced rotor: Unbalanced rotor of slurry pump or drive machine can also cause large vibration and noise of slurry pump. The solution is to rebalance the rotor.
3. Calibration of couplings: For slurry pumps with couplings, such as horizontal multi-stage slurry pumps, it may be due to poor alignment between the pump shaft and the motor shaft. The solution is to recalibrate the coupling.
4. Severe bearing wear: The bearing wear of the slurry pump is too severe, resulting in excessive clearance, which can also cause the slurry pump to vibrate greatly and be accompanied by noise. The solution is to consider replacing the bearings with new ones.
5. Loose foundation bolts: Loose foundation bolts or unstable foundations may also cause noise from the slurry pump. The solution is to check and tighten loose parts or replace them.
6. Low liquid level compared to pump: The user selected a horizontal slurry pump product, but during installation, the liquid level was lower than the pump. The lack of a bottom valve installed in the inlet pipeline resulted in the horizontal slurry pump being emptied. The solution is to install a bottom valve tank to divert water before starting the pump, or it is more suitable to use a self-priming slurry pump instead.
7. Loose parts of slurry pump: Long term operation may cause loose or damaged components of slurry pump, which may also lead to the generation of slurry pump noise. The solution is to tighten loose parts or replace them.
8. Supporting pipelines with slurry pumps: Loose brackets or pipelines supported by pumps can cause pipeline vibration and may also lead to the generation of slurry pump noise. The solution is to reinforce the pipeline support and not rely on the pump to support the pipeline.
9. Metal objects inside the slurry pump: Metal objects or other objects entering the pump, or friction between the impeller and the pump casing, may also cause the generation of slurry pump noise. The solution is to disassemble the pump body for inspection and eliminate friction.
The above is the reason for the noise during the operation of the submersible slurry pump. Welcome to consult.
