Further arrange: also offer at least three mounting holes on the described pump housing.
The preferred setting is: the quantity of described mounting hole is four.
Adopt technique scheme, by the mounting hole on the lower pump body, thereby realize the fixing of lower pump body and garage, and preferred amount is four.
Further arrange: described impeller shaft partly extends to the outer and formation driving section of the pump housing, is arranged with the profile of tooth belt wheel on this driving section.
Adopt technique scheme, because the belt wheel transmission stability is good, the transmission efficiency height is so the driving section on impeller shaft is provided with the belt wheel for the belt wheel transmission.
Further arrange: described impeller is the three pieces type helical runner again.
Adopt technique scheme, the three pieces type helical runner can effectively be realized the propelling movement to cooling liquid, and forms negative pressure in the impeller shaft position, improves the extraction to cooling liquid.
The beneficial effects of the utility model are: by the water seal part is set between impeller cavity and axis hole, thereby avoid cooling liquid to go out to reveal from axis hole, in order further to improve sealing effect, then impeller shaft adopts the shaft connecting bearing structure.This auto pump is simple and reasonable, improves good seal performance, has prolonged working life greatly.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, 2, present embodiment comprises the pump housing 1 that has impeller cavity 11, offers the axis hole 121 that extends in the impeller cavity 11 on this pump housing 1, in this impeller cavity 11 impeller 2 is installed, and is installed with impeller shaft 3 on the impeller 2, and this impeller shaft 3 is arranged in the axis hole 121.Impeller shaft 3 parts extend to the pump housing 1 outer and formation driving section, are arranged with profile of tooth belt wheel 5 on this driving section, cooperate with belt when profile of tooth belt wheel 5 is used for being with transmission.Impeller 2 is the three pieces type helical runner.
In order to improve the sealing between impeller cavity 11 and axis hole, so water seal part 4 is installed between impeller cavity 11 and axis hole, this water seal part 4 is sheathed on the impeller shaft 3, and is sealed and matched with impeller shaft 3 and axis hole respectively, and impeller shaft 3 adopts shaft connecting bearing.Water seal part 4 herein can be shell-like, and this water seal part 4 is sheathed on the impeller shaft 3, and water seal part 4 perisporiums and axis hole 121 openings closely recline, and forms and be sealed and matched firmly.
The pump housing 1 is formed (relative concept just up and down herein by upper pump casing 12 and lower pump body 13, during installation, which part namely can be described as last), 13 of upper pump casing 12 and lower pump bodies are provided with seal washer 6,13 of upper pump casing 12 and lower pump bodies are bolted to connection, ring group and outer shroud group in bolt is divided into, and each is organized inner bolt quantity and is four, same group of inner bolt be structural distribution ringwise all, and interior ring group 71 and outer shroud group 72 arranged concentric.Wherein, each bolt is positioned on the circular arc of same circle in the interior ring group 71, and five equilibrium distributes on this circle; And each bolt is positioned on the circular arc of same circle in the outer shroud group 72, and not five equilibrium distribution on this circle.Axis hole 121 is positioned on the upper pump casing 12.Among Fig. 1, the reference character of interior ring group 71 is oriented on the circle of dotted line place, and also four bolts in the namely interior ring group 71 are on this broken circle; Though and the reference character of outer shroud group 72 points to a screw position, but those skilled in the art can be readily appreciated that the actual circle that refers to this screw place of outer shroud group 72 reference characters, also are that four bolts in the outer shroud group 72 are on the circle at this screw place.
