Problems solved by technology
[0003] When the existing bottom valve water pump drains water, it mainly relies on the filtering effect of the bottom valve. The size of the bottom valve trough directly affects the filtering effect. If the bottom valve trough is small, the displacement will be affected. If the trough is large, foreign matter will enter the pump. , the water pump is stuck, affecting the use

Description
Technical field [0001] The invention relates to the technical field of water pumps, in particular to a drainage device suitable for a water pump with a bottom valve. Background technique [0002] Industrial water pumps are now indispensable water supply and drainage equipment for industrial and mining enterprises, especially large industrial and mining enterprises. For pumping equipment with high drainage lift and high water demand, most of them use multi-stage centrifugal pumps with bottom valve for drainage. [0003] Existing water pumps with a bottom valve mainly rely on the filtering effect of the bottom valve when draining water. The size of the bottom valve leakage groove directly affects the filtering effect. The bottom valve leakage groove is small and the drainage will affect the drainage. If the leakage groove is large, foreign matter will enter the pump. , The water pump is stuck, affecting the use. Summary of the invention [0004] The purpose of the present invention i...
