Abstract
The utility model discloses a water pump, which comprises a shell. A bearing with a shaft is arranged in the shell in a penetration way. A hub is sleeved at one end of the bearing with the shaft, and an impeller is connected to the other end of the bearing with the shaft. The bearing with the shaft is partially arranged outside the shell in the penetration way. The end part of the bearing with the shaft is extended out of the shell, and the impeller is arranged on the end part. A part of the bearing with the shaft remains in the shell, and a water seal is arranged between the part and the shell. A drain hole is formed in the shell. A blank cap is arranged on the drain hole of the shell. By the structure, the integral water seal is arranged between the bearing with the shaft and the shell, so that the splashing of liquid onto the end of the bearing with the shaft, which is provided with the hub, can be prevented when the impeller rotates to ensure the normal operation of the water pump and effectively prolong the service life of the water pump.
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; Shaft connecting bearing is arranged in the housing, and an end of shaft connecting bearing is provided with the wheel hub that is connected with drive wheel, and the other end of shaft connecting bearing is provided with the impeller that is connected with liquid; But because present existing automobile cooling water pump; The water proof device is not set between its water pump shaft connecting bearings and the housing, therefore when drive wheel rotates through the shaft connecting bearing impeller, can causes liquid to be splashed to that end of shaft connecting bearing installing drive wheel with wheel rotation usually; Influence the normal operation of drive wheel, and the working life that shortens 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; Be equipped with shaft connecting bearing in the described housing; One end of shaft connecting bearing is arranged with wheel hub, is connected with impeller on the other end of shaft connecting bearing, and described shaft connecting bearing partly is located in outside the housing; Said shaft connecting bearing passes on the outer end of housing impeller is housed, and said shaft connecting bearing remains between interior part of housing and the housing and is provided with water seal.
The beneficial effect of the utility model is: adopt said structure; Owing between said shaft connecting bearing and housing, set up the integrated type water seal; Therefore liquid splash is equipped with this end of wheel hub in the time of can preventing wheel rotation to shaft connecting bearing; Thereby guarantee the normal operation of water pump, prolonged the working life of water pump effectively.
The utility model can further be set to described housing and be provided with spilled water hole, on the spilled water hole of said housing stifle is housed.
