Description

Technical Field

[0001] This utility model relates to the field of automotive water pump technology, and in particular to a sealed automotive water pump housing. Background Technology

[0002] The car water pump is a major component of a car. It mainly serves as the driving mechanism for circulating the cooling water in the car engine. Its basic structure consists of parts such as the water pump housing, connecting plate or pulley, water pump shaft and bearing or shaft-connected bearing, water pump impeller and sealing device.

[0003] Currently, the sealing structure between the two housings of automotive water pumps is basically based on a single sealing ring. The quality of this seal is generally poor, resulting in poor overall sealing performance. Over time, this can lead to water leakage, significantly reducing the lifespan of the water pump. Therefore, we propose a sealing automotive water pump housing to solve the above problems. Utility Model Content

Each connecting plate has a connecting screw hole on one side and a fastening screw on its exterior. One side of one housing has a sealing assembly including two annular sealing grooves. An annular sealing ring is located on the exterior of one housing. An annular sealing pressure plate is connected to the outer surface of the annular sealing pressure plate. An annular sealing positioning plate is connected to the outer surface of the annular sealing pressure plate. A set of positioning holes is located on the outer surface of the annular sealing positioning plate. Each housing has a set of positioning screw holes on its outer surface, and a set of positioning screws is located on the exterior of one housing.

[0007] In a further embodiment, one side of the housing is connected to two support frames, and each support frame has two mounting holes on one side.

[0008] In a further embodiment, each of the support frames has a connecting block attached to its outer surface, and one side of each connecting block is connected to one side of a housing.

[0009] In a further embodiment, a nameplate is attached to the outer surface of one of the housings, and the outer surface of the nameplate is engraved with markings.

[0010] In a further embodiment, one side of the housing is connected to a water inlet pipe, and the other side of the housing is connected to a water outlet pipe.

[0011] In a further embodiment, a controller is connected to one side of one of the housings, and each of the positioning screw holes is adapted to a positioning screw.

[0012] In a further embodiment, each of the connecting screw holes is adapted to a fastening screw, and the annular sealing ring is adapted to an annular sealing groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This device uses fastening screws that fit into connecting screw holes to easily connect and fix two housings. It also features an annular sealing groove that fits into an annular sealing ring, an annular sealing pressure plate that fits into the housing, an annular sealing positioning plate that fits into the housing, and positioning holes and positioning screw holes that fit into positioning screws. This provides three sealing measures for the housing, maximizing the sealing effect of the housing and increasing its service life. Attached Figure Description
