Description
Technical field
The utility model relates to a kind of auto pump assembly, especially a kind of auto pump assembly with anti-internal corrosion function.
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.And internal leak needs the long period between being found, so when finding, inner member has often suffered corrosion, needs to change again, thereby has improved production and maintenance cost virtually.In addition, the suction chamber that water pump body and impeller form mostly is the annular space structure, when cooling water flow into impeller from suction chamber, cooling water closes up in the middle of suction chamber two side direction and since impeller shaft at a high speed rotation can occur rotatablely moving and make cooling water form eddy current, thereby can cause water-sealed component to occur the lack of water phenomenon on every side, cause the dynamic and static ring frictional surface temperature of water-sealed component too high, easily scaling loss water seal bellows causes water-sealed component to leak, and water pump complement was lost efficacy.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of anti-internal corrosion that has, and can stop the auto pump assembly that current rotatablely move in the suction chamber.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of auto pump assembly, 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 multiple ribbed 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, offer apocenosis passage on the described pump housing, an end and the axis hole of this apocenosis passage are conducted, and the other end extends to outside the pump housing.
Further be set to: the position that is positioned at axis hole on the described impeller shaft is arranged with bi-face sealed ball bearing.
Adopt technique scheme, the water seal part avoids cooling liquid to enter axis hole from impeller cavity as the first road barrier; And bi-face sealed ball bearing is the second road barrier, can prevent effectively that cooling liquid from leaking in axis hole, further guarantees self seal.
Further be set to: on the described apocenosis passage and the end that is conducted of axis hole is between bi-face sealed ball bearing and water seal part.
Adopt technique scheme; when cooling liquid penetrates the water seal part and enters in the axis hole; then permeating the cooling liquid of coming in can be external through the apocenosis passage excavationg pump; make infiltration problem in time to be found, and protected the interior impeller shaft of axis hole and bi-face sealed ball bearing etc. not to weather in time.
Further be set to: also be provided with the suction chamber that is conducted with impeller cavity in the described pump housing, convex with the flow-disturbing muscle on the inwall of this suction chamber.
Adopt technique scheme, when cooling liquid enters into suction chamber, because the setting of this flow-disturbing muscle, meeting stops rotatablely moving of the interior current of suction chamber and weakens the formation of eddy current to a certain extent, can access abundant cooling around making the water seal part, avoid the too high phenomenon that burns out the water seal bellows of water-sealed component temperature, thereby avoided the damage of water seal part, prolonged the working life of auto pump assembly.
Further be set to: described suction chamber is long tubular, and 30 ~ 90 ° of angles that axially are of the axial and suction chamber of flow-disturbing muscle are arranged.
Preferably be set to: the 60 ° of angles that axially are of the axial and suction chamber of described flow-disturbing muscle are arranged.
Adopt technique scheme, the flow-disturbing muscle of this angle setting can effectively stop rotatablely moving of the interior current of suction chamber and weaken the formation of eddy current to a certain extent.
The beneficial effects of the utility model are: when cooling liquid penetrates the water seal part and enters in the axis hole, by set apocenosis passage, make cooling liquid in time be discharged axis hole, and be convenient to observe the seepage phenomenon, thereby the very first time is carried out necessary maintenance, avoids further loss.
