Description

Technical field:

[0001] The utility model relates to the technical field of water pump casing castings, and more specifically to a pressure-resistant and deformation-resistant water pump casing casting. Background technology:

[0002] At present, the water pump housing is generally obtained by casting combined with machining. There is a water pump housing on the market, the middle part of which is a water passage cavity, and a cylindrical annular valve seat (also called a pump seat) is arranged in the water passage cavity. The two sides of the water pump housing are respectively provided with a water inlet pipe and a water outlet pipe. The water inlet pipe is connected to the inner cavity of the valve seat, and the water outlet pipe is connected to the water passage cavity of the water pump housing. Its structure is shown in the attached figure. Figure 1 As shown in the casting shell, the casting shell is designed to have a thin-wall structure on all sides on the basis of meeting the inner pressure. The thin-wall structure can effectively reduce the weight of the water pump housing, save manufacturing costs, and facilitate the transportation of the water pump housing; but in the transportation process, due to improper operation, such as directly leaving the water pump housing on the ground, the thin wall of the water pump housing is damaged and deformed by external impact; and the manufactured water pump housings will be placed in a stacked manner. Sometimes, in order to improve the utilization of space, some water pump housings will be placed in the form of sideways stacking. When the water pump housings are sideways stacked, the bottom water pump housing may be deformed, so a high-strength water pump housing structure needs to be designed. Utility model content:
