Description

Technical Field

[0001] The utility model belongs to the field of all-terrain vehicles, in particular to a detachable water pump mechanical structure for an engine. Background Art

[0002] At present, the water seal components in the water pump structure of all-terrain vehicles on the market are mostly directly installed into the engine box, such as Figure 1 As shown, the lower water seal assembly of this structure is press-fitted onto the casing, and the upper water seal assembly is press-fitted onto the water pump impeller. The disadvantage of this structure is that when the water seal assembly has sealing problems due to aging during long-term engine operation, it is difficult to disassemble and replace, and the maintenance cost is high. Summary of the Invention

[0003] The utility model aims to address the technical defects of the existing technology and provide a detachable water pump mechanical structure for an engine, so as to solve the technical problems that the water seal component in the water pump structure is difficult to disassemble and replace and has high maintenance costs.

[0004] In order to achieve the above technical objectives, the present invention adopts the following technical solutions:

[0005] A detachable water pump mechanical structure for an engine includes a casing, a water pump impeller, a water seal assembly, and a water pump body. The water pump body is fixedly connected to the casing, and a seal is maintained between the water pump body and the casing. The water seal assembly is arranged between the water pump body and the water pump impeller.

[0006] Preferably, an outer annular platform is provided on the outer wall of the water pump body, and the water pump body fits with the inner wall of the box body through the outer annular platform. A first annular groove and a second annular groove are provided on the outer wall of the water pump body, and O-rings are installed in the first annular groove and the second annular groove.

[0007] Preferably, the first annular groove and the second annular groove are respectively located above and below the outer annular platform.

[0008] Preferably, a trough body is provided on the water pump body, and an inner annular platform is provided on the inner wall of the trough body, and the water pump body is matched with the water seal assembly through the inner annular platform.

[0009] This utility model provides a detachable water pump mechanical structure for an engine. This technical solution incorporates a water pump body structure between the water seal assembly and the casing. A double-layer O-ring seal is used between the water pump body and the casing, and the water seal assembly is mounted on the water pump body. In this way, if a water seal problem occurs in the engine, the water pump body can be removed from the casing and the water seal assembly can be press-fitted onto the water pump body. This structure effectively protects the casing from damage during removal of the water seal assembly, ensuring reliable installation and easy disassembly, reducing maintenance costs.

[0010] This utility model is suitable for use with all-terrain vehicle power output engines and serves as a seal in the engine cooling system. This design effectively addresses the difficulty of disassembling the water seal assembly during maintenance, effectively protecting the housing from damage during disassembly. It also offers the advantages of reliable installation, easy disassembly, and low maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS
