[0030] like Figures 1 to 3 As shown, this utility model discloses an engine water pump assembly structure, including a pump base 5, a pump body 1 placed on the pump base, and an impeller placed in the pump body. The pump base is provided with a water channel 53. The pump base 5 is integrated with an air compressor mounting bracket 11 for fixing an air compressor. The air compressor mounting bracket 11 is provided with a first positioning pin sleeve 2 for positioning the air compressor.

[0031] The water outlet of the water channel is provided with a cylinder mounting surface 51, and a second positioning pin sleeve 4 for positioning the cylinder is provided on the cylinder mounting surface 51.

[0032] The cylinder mounting surface is provided with mounting rings 52 around the water outlet for fitting the sealing ring 3.

[0033] By adopting the above structure, by integrating the air compressor mounting bracket (11) on the pump base (5) and using the first positioning pin sleeve 2 to achieve air compressor mounting positioning, not only is the air compressor assembly efficiency and quality improved, but the overall assembly space occupied is also reduced.

[0034] The first locating pin sleeve 2 fulfills the installation position requirements of the air compressor; the second locating pin sleeve 4 fulfills the installation position requirements of the cylinder block.

[0035] The sealing ring 3 can use an existing sealing ring structure. However, to improve sealing performance and anti-loosening performance, it is preferable to use a structure such as... Figure 4 The structure shown has raised structures 31 on both the inner and outer diameter surfaces of the sealing ring 3.

[0036] To improve the installation stability of the air compressor, a reinforcing rib 14 is provided between the pump base and the air compressor mounting support 11. Preferably, there are at least two reinforcing ribs.

[0037] For example, such as Figure 3 As shown, the reinforcing ribs are set on the pump base in a triangular structure with a thickness of 6mm.

[0038] By adding reinforcing ribs, the strength of the pump base is increased to ensure that it can withstand the load of the air compressor.

[0039] Furthermore, the inlet of the water channel 53 is provided with an air compressor coolant return hole 12 and a small circulation return hole 13 to realize the cooling circulation function of the air compressor and the engine.

[0040] To improve structural stability, the dimensional tolerances of the first locating pin sleeve 2 and the hole on the air compressor mounting bracket 11 are made by transition fit.

[0041] To improve structural stability, the dimensional tolerance between the second locating pin sleeve 4 and the hole on the cylinder mounting surface 51 is achieved by an transition fit.

[0042] By adopting the above-mentioned engine water pump assembly structure, the water pump and air compressor support are integrated together. This not only preserves the independence of water pump leak detection but also simplifies the engine assembly process and makes the assembly space more compact. It also achieves the independence of the water pump assembly, which is convenient for maintenance and replacement.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
