Abstract
The utility model discloses a water pump, which comprises a shell, a shaft bearing and a cover board, wherein the shaft connection bearing is inserted into the shell; a closed chamber is formed between the cover board and the shell; one end of the shaft connection bearing is positioned in the closed chamber of the shell; blade wheels are sleeved at the end of the shaft connection bearing; and a wheel hub is fixedly arranged at the other end of the shaft connection bearing, which extends out of the shell. By adopting the structure, the blade wheels work in the closed chamber formed between the shell and the cover board, so that outside impurities or dust can be effectively prevented from being attached to the blade wheels; and therefore, the blade wheels can work normally, and the service life of the water pump is prolonged.
Description
Technical field
The utility model relates to a kind of water pump, is specifically related to a kind of automobile cooling water pump.
Background technique
Automobile cooling water pump is to carry automobile engine cooling liquid to quicken the mechanical device of flow circuit cooling.Automobile cooling water pump mainly comprises housing, shaft connecting bearing, impeller, and shaft connecting bearing is located in the housing, and impeller is installed on the end of shaft connecting bearing; But present existing automobile cooling water pump, its impeller normally expose in the housing outer end, and therefore extraneous impurity or dust are easily attached on the impeller; Thereby when wheel rotation; Impeller is damaged, or influence the proper functioning of impeller, shortened the working life of water pump.
Summary of the invention
To the deficiency of existing technology, the utility model provides a kind of simple in structure, working life long water pump.
For realizing above-mentioned purpose, the utility model provides a kind of water pump, comprises housing, shaft connecting bearing; Shaft connecting bearing is located in the housing; Also comprise cover plate, constitute an airtight cavity volume between described cover plate and the housing, an end of shaft connecting bearing is positioned at the airtight cavity volume of housing; And on the end of this end, be socketed with impeller, shaft connecting bearing passes on the outer the other end of housing and is installed with wheel hub.
The beneficial effect of the utility model is: adopt said structure; Because described impeller is in the airtight cavity volume that is made up of housing and cover plate, to work; Therefore can avoid introduced contaminants or dust attached on the impeller effectively, guarantee the proper functioning of impeller, prolong the working life of water pump.
The utility model can further be set to also be provided with between said cover plate and the housing paper washer.
The utility model also can further be set to be provided with water seal between shaft connecting bearing and the housing.
The utility model also can further be set to offer some intake-outlets on the described housing, and is connected with the water pipe of different size size on some intake-outlets respectively.
