What should be done if the slurry pump fails to discharge water?

Let's learn how to solve the problem of slurry pump not discharging water. Below, Furkey will give you a brief introduction. Let's take a look together!

There are quite a few cases of water failure during the use of slurry pumps, so what are the reasons and how can we do it if there are problems?

Inspection location: The first one is the intake pipe or the inlet flange of the slurry pump for air intake. Method: Overcoming the air intake factor;

The second issue is the absence of shaft seal water or the occurrence of air intake at the shaft seal. The solution is to add shaft seal water and overcome the air intake factor

The third issue is that the outlet valve is not closed before starting or the outlet valve of the slurry pump is opened too quickly. The solution is to follow the start-up procedures of the slurry pump;

The fourth issue is that the suction port of the slurry pump is blocked, and we only need to remove the blockage;

The fifth issue is that the vacuum tank is leaking or the size of the vacuum tank is unreasonable. The solution is: customer service intake factors or improving the size of the vacuum tank;

The sixth one is the head of the slurry pump and the head of the pipeline device. The solution is to increase the head of the slurry pump and match it with the pipeline;

The seventh issue is that the cavitation margin of the pipeline is less than the necessary cavitation margin of the slurry pump. The solution is to modify the pipeline device system to increase the cavitation margin of the pipeline or replace the slurry pump with one that meets the cavitation performance requirements of the pipeline;

The eighth option is to choose a smaller slurry pump despite having a high slurry concentration, simply replace it with a larger diameter slurry pump.
