Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
As shown in Figs 1-4, a kind of water pump cover, the seal groove 7 including pump case main body 1 and mounted on 1 side of pump case main body,
Integrated setting has water outlet 2 on the periphery of the pump case main body 1, and playpipe 3 is fixedly connected on the water outlet 2, described
The opposite side integrated setting of pump case main body 1 has a water sucking mouth 5, and being internally provided with of the pump case main body 1 accommodates water pump vane
Inner cavity 8, the edge of the inner cavity 8 is equipped with inside vortex line 10 and outer vortex lines 11 successively from inside to outside.
The inner cavity 8 connects respectively with water outlet 2 and water sucking mouth 5, by suction hole 5, can in cavity 8 water pump vane
Flow is sucked into inner cavity during rotation, meanwhile, water body out of water outlet 2 can be discharged, realized by water pump vane high-speed rotation
Continuous liquid supply.
Also integrated setting has fixed feet 6 in the pump case main body 1, and fixed feet 6 is distributed on the periphery of pump case main body 1,
The fixed feet 6 is equipped with straight hole, by bolt, conveniently can carry out installation fixation to pump case main body 1.
