Dredge pump problems and solutions-no or inefficient liquid is piped by dredge pump
1, device system problems
Inspection item: intake air at the suction line or pump inlet flange;
Remedy: Overcome the air intake factor;
Check item: air intake without shaft seal or shaft seal;
Remedy: Add shaft seal water to overcome the intake factor;
Check item: the outlet valve is not closed before starting or the slurry pump starts to open the outlet valve too fast;
Remedy: Operate according to the slurry pump startup procedure;
Inspection item: blockage of the suction port of the slurry pump;
Remedy: remove the blockage;
Inspection items: vacuum tank leak or vacuum tank size is unreasonable;
Remedy: Overcome the air intake factor or improve the vacuum tank size, please call Do Pump Industry
2, slurry pump selection calculation problem
Inspection item: the pump head is lower than the head of the pipeline unit;
Remedy: Improve the pump head to match the pipeline;
Inspection item: the NPSH of the pipeline is less than the necessary NPSH of the pump;
Remedy: Renovate the pipeline installation system to increase the NPSH of the pipeline or replace the pump with the cavitation performance to meet the pipeline requirements;
Inspection item: the pump with a large slurry concentration is small;
Remedy: Replace the large diameter slurry pump;
