Abstract
The utility model discloses an auto water pump assembly with a seal ring. The auto water pump assembly comprises a pump provided with an impeller cavity, a shaft hole extending to the inside of the impeller cavity is formed in the pump, an impeller is installed in the impeller cavity, an impeller shaft is fixedly mounted on the impeller and arranged in the shaft hole in a penetrating mode and extends out of the pump, a belt pulley is fixed at a position of the impeller shaft, which extends out of the pump, a water seal member is sleeved at a position of the impeller shaft, which is between the impeller cavity and the shaft hole, the water seal member is matched with the impeller shaft and the shaft hole respectively, the impeller shaft is a bearing with shaft, a seal groove which is axially arranged around the impeller shaft is formed in the bearing peripheral wall of the impeller shaft, and the seal ring is mounted in the seal groove. The bearing with shaft is compact in structure, so that an anti-leakage effect can be improved to the greatest extent; and the seal ring is sleeved at the bearing position of the impeller shaft, so that leakage can be further delayed and discovered by maintainers timely, and losses can be reduced.
Description
Technical field
The utility model relates to a kind of auto pump assembly, especially a kind of auto pump assembly with seal ring.
Background technique
At present, auto pump is indispensable important component part on the automobile, and existing auto pump generally is made up of water pump body, axle, belt pulley and impeller etc.But because structural defective, a lot of auto pumps can produce problem such as leak after using for a long time, can influence the normal use of automobile when serious.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is a kind of simple and reasonable that the utility model provides, and improves sealability, the auto pump assembly of the band seal ring that increases the service life.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of auto pump assembly with seal ring, comprise the pump housing that has impeller cavity, offer the axis hole that extends in the impeller cavity on this pump housing, impeller is installed in the impeller cavity, be installed with impeller shaft on the impeller, this impeller shaft is arranged in the axis hole and extends to outside the pump housing, extend to the outer partial fixing of the pump housing on the impeller shaft belt pulley is arranged, the position that is positioned on the impeller shaft between impeller cavity and axis hole is arranged with the water seal part, this water seal part is sealed and matched with impeller shaft and axis hole respectively, described impeller shaft is shaft connecting bearing, offer the seal groove that the wound impeller axle axially arranges on the bearing perisporium of this impeller shaft, described seal ring is installed in the seal groove.
Preferably be set to: the quantity of described seal groove has twice at least.
Preferably be set to: the quantity of described seal groove is twice.
Preferably be set to: described seal groove is positioned at the neutral position of impeller shaft upper bearing (metal).
Preferably be set to: each plane, seal groove place is parallel to each other.
Further preferably be set to: described belt pulley is multiple ribbed pulley.
The beneficial effects of the utility model are: the compact structure of shaft connecting bearing, so can improve the effect of leakage proof to greatest extent, and the sheathed seal ring in impeller shaft upper bearing (metal) position can further delay the generation of seepage, so that the attendant finds timely, thereby reduce loss.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, present embodiment comprises the pump housing 1 that has impeller cavity 11, offer the axis hole that extends in the impeller cavity 11 on this pump housing 1, impeller 2 is installed in the impeller cavity 11, be installed with impeller shaft 3 on the impeller 2, this impeller shaft 3 is arranged in the axis hole and extends to outside the pump housing 1, and extending to the pump housing 1 outer partial fixing on the impeller shaft 3 has belt pulley 4, and this belt pulley 4 is multiple ribbed pulley.The position that is positioned on the impeller shaft 3 between impeller cavity 11 and axis hole is arranged with water seal part 5, and this water seal part 5 is sealed and matched with impeller shaft 3 and axis hole respectively.
In the present embodiment, impeller shaft 3 is shaft connecting bearing, so axle and bearing adopt integrative-structure on the impeller shaft 3, and offer the seal groove 311 that wound impeller axle 3 axially arranges on bearing 31 perisporiums of impeller shaft 3, the seal ring (not shown) is installed in the seal groove 311.Wherein, the quantity of seal groove 311 is twice, and each plane, seal groove 311 place is parallel to each other.
In the utility model, the compact structure of shaft connecting bearing, so can improve the effect of leakage proof to greatest extent, and the sheathed seal ring in impeller shaft 3 upper bearing (metal)s, 31 positions can further delay the generation of seepage, so that the attendant finds timely, thereby reduces loss.
