Abstract

The invention discloses a water pump. The water pump comprises a pump body with an inlet and an outlet; the inlet and the outlet communicate with each other through a main flow channel; the water pumpis characterized in that the pump body is further provided with a recoil port; the recoil port communicates with the main flow channel through a secondary flow channel; the recoil port and the inletare located at the same side of the pump body; the water pump further comprises a filter element that can slide along the pump body and can be switched between the inlet and the recoil port; when thefilter element is located at the inlet, a medium entering the pump body is filtered; and when the filter element is located at the recoil port, the filter element is reversely rinsed by the medium. Compared with the prior art, the water pump disclosed by the invention can be used for cleaning the filter element without shutdown, so the working efficiency of the water pump is improved.

Description

technical field [0001] The present application relates to the field of pumps, in particular to a water pump. Background technique [0002] A water pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsions, and suspoemulsions. And liquid metal, etc., can also transport liquid, gas mixture and liquid containing suspended solids. [0003] When the pump is working, the medium may be mixed with more impurities such as sand and gravel. If the pump works continuously for a long time, when the accumulation of impurities reaches a certain level, the parts such as the blades of the pump will not run smoothly, and the function will be reduced. It will affect the pump body structure of the water pump and increase the wear and loss of the machine. [0004] Currently, th...
