How to improve the pressure of the submersible dredge pump
In the process of using the submersible dredge pump, dredge pump users may encounter the pump is working innormally and it has a very low head, which can not achieve good performance compare with the dredge pump design, so what causes the low head of the submersible dredge pump? Is there any way to solve it?
Reasons for low lift:
1. Intake air intake system;
2. The suction line or impeller is blocked;
3. The inlet valve of the submersible slurry pump is not deployed or the valve is damaged, causing the pump to cavitation;
4, the use of the submersible slurry pump pump head is lower than the actual head of the pipeline, resulting in a small pump flow;
5. The NPSH of the pipeline is smaller than the NPSH of the submersible slurry pump, resulting in a small pump volume;
6. The slurry concentration is too large.
Submersible slurry pump use method solution:
1. Eliminate the cause of intake air;
2. Reduce the concentration of the slurry of the submersible slurry pump or change the pump of the larger size;
3. Expand the inlet valve or replace the new valve;
4. Improve the head of the submersible slurry pump;
5. Eliminate blockages;
6. Make the pipeline device so that the NPSH of the pipeline is greater than the pump required for the NPSH or the cavitation performance to meet the requirements of the pipeline installation.
