The diesel self priming pump is a fluid equipment that integrates self priming and non clogging pollution discharge, and uses diesel engine driven axial reflux for external mixing. It has a large suction force and can suck water into the pump, which then pumps it to other places. When using a diesel engine self priming pump for the first time, it is necessary to fill the pump with water before starting it for use, so there is no need to refill it in the future. Diesel self priming pumps can be widely used for municipal sewage control, drought relief, river aquaculture, light industry, papermaking, textile, food, chemical, electrical, fiber, slurry, and mixed suspension. The diesel self priming pump can suck and discharge liquids containing large particle solids and long fiber impurities.
During the use of diesel engine self priming pumps, there are always problems like this. Today, I will take you to understand what causes the diesel engine self priming pump to not be able to absorb water?
1. The pipeline is not sealed and leaks air
The pipeline of the diesel self priming pump is not sealed and leaks, resulting in the diesel self priming pump not self priming. Sealing the pipeline can solve the problem.
2. The diesel self priming pump itself is not sealed
There is a problem with the mechanical seal of the diesel engine self priming pump, which leads to the diesel engine self priming pump not self priming. Simply replacing the mechanical seal can solve the problem.
3. Exceeding the head of the diesel self priming pump
The installation position of the diesel engine self priming pump is too high, and the water inlet is too low. Causing the suction head to exceed the acceptable range of the diesel self priming pump, resulting in non self priming. Lowering the installation position of the pump can solve the problem.
4.The linkage shaft of the diesel self priming pump is stuck
The linkage shaft of the diesel self priming pump is stuck, causing the impeller to not rotate normally and unable to form self priming, resulting in non self priming. Check and adjust the linkage axis to solve the problem.
5.的进口和出口the diesel engine self priming pump are installed upside down
During installation, a fundamental error occurred, causing the inlet and outlet to be installed backwards, resulting in non self priming. Remove and reinstall to solve the problem.
6. There is a leak in the pump casing of the diesel self priming pump
During the production of the pump casing of the diesel self priming pump, sand holes appeared, resulting in non self priming. Check the pump casing and block the sand to solve the problem.
