Description

Technical Field

[0001] The utility model relates to the technical field of water pump sealing parts, in particular to a water pump guide shell rubber component. Background Art

[0002] At the upper water outlet of the automobile engine, there is a water pump, which is driven by a fan belt to pump out the hot water in the water channel of the engine cylinder and pump in the cold water. During the operation of the water pump, a certain gap needs to be left between the impeller and the guide casing, and liquid leakage loss is inevitable. Therefore, a sealing device is needed to reduce or avoid liquid leakage.

[0003] However, most of the existing sealing devices are sealed directly by means of a sealing ring, but the sealing ring is prone to relative rotation with the guide shell during use, thereby accelerating the wear of the sealing ring and causing the service life of the sealing ring to be reduced. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a water pump guide housing rubber assembly, which solves the problems raised in the above-mentioned background technology.
