Pump head of water pump

Abstract

The invention provides a pump head of a water pump. The pump head of the water pump comprises a body, wherein the top and the left side of the body are separately provided with a water outlet end anda water inlet end; the water inlet end and the water outlet end are in communication through an impeller cavity arranged in the body; a mounting hole is formed in the rear side of the body; a filter barrel sleeves outside the water inlet end; the left end and the right end of the filter barrel are separately sealed and opened; filter holes are densely distributed in the barrel wall of the filter barrel; a ring-shaped flange is integrally formed on the outer side wall of the right end of the filter barrel; a ring-shaped slot which is opposite to the ring-shaped flange is formed in the outer wall of the body; the ring-shaped flange is positioned in the ring-shaped slot; a ring-shaped sealing cushion is clamped between the bottom wall of the ring-shaped slot and the ring-shaped flange; at least two threaded holes I which are blind holes are formed in the right end surface of the ring-shaped flange; threaded holes II are formed in the bottom wall of the ring-shaped slot in a penetrating mode; through holes I are formed in the ring-shaped sealing cushion; the threaded holes I, the threaded holes II and the through holes are the same in quantity; studs are in screw joint in the threadedholes II; and ends of the studs are in screw joint in the bolt holes I. The pump head of the water pump is better in aesthetic sense.

Description

technical field [0001] The invention relates to a water pump, in particular to a pump head of the 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. [0003] Existing water pumps such as a water pump disclosed in the Chinese patent library [Application No.: 201810541236.4] include a filter screen cover, a water inlet section, an outer cylinder, a motor, a shock-absorbing ring, an intermediate bracket, a mechanical seal, a pressure-resistant cylinder, a deflector, The impeller, guide vane and water outlet section, the motor cooling method of the water pump adopts water cooling, and the heat generated by the motor operation is naturally cooled and taken away by ...
