Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of reinforcement structure of water pump pump case, including stream Body room 1, the outer surface of the fluid chamber 1 are fixedly connected with several reinforcing ribs 7, the fluid chamber 1 positive four corners difference It is fixedly connected there are four strike plate 2, the tilt angle of the strike plate 2 is 45 degree, and the back side of the fluid chamber 1 is set It is equipped with water outlet 8, the upper surface of the fluid chamber 1 is provided with front cover 11, and the upper surface of the front cover 11 passes through bolt b and protection The lower surface of cover 6 is detachably connected, and the lower surface of the fluid chamber 1 is fixedly connected with the upper surface of filter plate 10.

In the present embodiment, the material of the LP blades pad is rubber material, and the LP blades pad setting of rubber material is pumping Shell inner wall reduces the fluid impact that pump housing endophragm is subject to, increases the service life of fluid chamber.

In the present embodiment, in withdrawn fluid, fluid connects under the conditions of flow at high speed and pressure change with fluid water pump There is a phenomenon where cavernous corrosion failures on the metal surface of touching, so that strike plate 2 and LP blades pad 3 reduce fluid convection The reinforcing rib 7 of the impact and erosion of 1 inner wall of body room, 1 surrounding of fluid chamber increases the intensity of fluid chamber 1, prevents fluid chamber 1 from flowing It deforms or cracks under the flow at high speed and pressure change of body, by being provided with reinforcing rib 7 in the surrounding of fluid chamber 1, thus plus Strengthening tendons 7 increase the intensity of fluid chamber 1, prevent fluid chamber 1 from deforming or cracking under the flow at high speed and pressure change of fluid, By being provided with shield 6 in the upper surface of front cover 11, there is no protection for the motor of original 11 top of front cover, and are in often In water or under solar exposure, it is extremely easy to appear damage, so that shield 6 can protect the motor on water pump, is passed through Strike plate 2 is provided in fluid chamber 1, and the tilt angle of strike plate 2 is 45 degree, so that strike plate 2 can be with Weaken the impact of fluid for the inner wall of fluid chamber 1.

Further, the inner wall of the fluid chamber 1 is provided with LP blades pad 3, by being provided with LP blades in fluid chamber 1 Under the conditions of flow at high speed and pressure change cavernous corrosion failure occurs for pad 3, fluid on the metal surface that contacts with fluid Phenomenon, so that LP blades pad 3 can reduce the impact and erosion of 1 inner wall of fluid convection body room.
