Description

Filter before self priming pump

Technical Field

The utility model relates to the technical field of filters, in particular to a filter before a self-priming pump.

Background

The self-priming pump belongs to self-priming centrifugal pump, and has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long service life, stronger self-priming capability and the like. The self-priming pump works in the principle that water is filled in the pump (or water is stored in the pump shell) before the pump is started, and after the self-priming pump is started, the impeller rotates at a high speed to enable water in the impeller channel to flow to the volute, at the moment, the inlet forms vacuum, so that the water inlet check valve is opened, and water in the suction pipe enters the pump.

The existing household self-priming pump brings great convenience to the family life, and the self-priming pump is generally used for filtering after pumping water to the pressure tank in the use process. Too large particles enter the self-priming pump along with water, and the pressure of the pressure tank is reduced due to poor sealing of the water stop valve caused by sediment, so that the motor is frequently started repeatedly under the condition that the water stop valve leaks, the electricity consumption is too high, and the service life of the self-priming pump is seriously damaged.

Therefore, in view of the above-described technical problems, there is a need for a pre-pump filter of a self-priming pump so that sediment cannot enter the self-priming pump.
