Reasons and Solutions for Blockage of Slurry Pump

---

• TIME : 2025-04-14

Reason 1: The installation of the pump is not horizontal

If the installation of the pump is not horizontal, it may cause vibration of the slurry pump during operation, leading to blockage.

Solution 1: Check the level of the pump body

During installation and operation, the level of the pump body should be checked to ensure smooth operation of the pump.

Reason 2: Cavitation and imbalance of pump impeller

Cavitation and imbalance of pump impeller are also one of the reasons for blockage of slurry pump.

Solution 2: Adjust the installation height and outlet valve

The problems of cavitation and pump impeller imbalance can be solved by reducing the installation height, adjusting the outlet valve, and reducing the inlet resistance.

Reason 3: Large amount of slag or inappropriate slag water ratio

When the slag content in the water is high, the capacity of the slag pump decreases and the slag pump is prone to blockage. In addition, if the slag water ratio is not set properly, it can also cause blockage of the slurry pump.

Solution 3: Adjust the slag flow rate and slag water ratio

Ensure that the slag flow rate does not exceed the maximum design value of the pump (such as 6t/min), and the slag water ratio does not exceed 1:8 to avoid blockage.

Reason 4: Inappropriate pump speed

If the pump speed is too fast, the pump chamber may produce too high pressure, resulting in bubbles and fluid turning into foam, thus blocking the pump.

Solution 4: Adjust the pump speed

According to different conveying media and application scenarios, the speed of the pump can be adjusted appropriately to optimize its performance.

Reason 5: Property issues of the conveying medium

If the viscosity of the conveying medium is too high or contains a large amount of particulate matter, it may also cause blockage of the slurry pump.

Solution 5: Change the properties of the conveying medium

It can be improved by adjusting concentration, viscosity, or using other types of media.

Reason 6: Lack of regular maintenance and cleaning

After running for a period of time, the slurry pump may accumulate sediment, dirt, and other residues adhering to the surface of the pump chamber, which may leave the pump chamber during operation and cause blockage.

Solution 6: Regular maintenance and cleaning

It is very important to regularly clean the pump room and inspect various components of the pump, which can effectively extend the service life of the slurry pump and avoid blockage.

Through the above methods, the problem of slurry pump blockage can be effectively prevented and solved, ensuring the normal operation of the slurry pump and improving work efficiency.
