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 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, 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, the position that is positioned at axis hole on the described impeller shaft is arranged with bi-face sealed ball bearing, the position that is positioned on the impeller shaft between impeller cavity and axis hole is arranged with the water seal part, and this water seal part is sealed and matched with impeller shaft and axis hole respectively.
Further arrange: the quantity of described bi-face sealed ball bearing is two, and two bi-face sealed ball bearings lay respectively in the axis hole two relative far-ends.
Adopt technique scheme, the quantity of bi-face sealed ball bearing is two, helps to improve the sealing of impeller shaft in axis hole, has double shield for the leakage that prevents cooling liquid.
Further arrange: described impeller cavity is provided with the water sucking mouth, and this water sucking mouth is connected with the suction sleeve of band suction chamber, and this suction chamber is horn-like, and the opening near impeller cavity is osculum in the suction chamber.
Adopt technique scheme, suction chamber is horn-like on the suction sleeve, and the osculum of suction chamber and impeller cavity UNICOM, the effect when then helping to utilize fluid flow characteristics to improve the absorption cooling liquid.
Further arrange: described impeller cavity is provided with drain opening, and this drain opening is connected with the waste pipe of band drip chamber, and this drip chamber is straight-tube shape.
Adopt technique scheme, drip chamber is straight-tube shape on the waste pipe, helps the bat of cooling liquid to discharge.
Further arrange: described impeller shaft partly extends to the outer and formation driving section of the pump housing, and this driving section is provided with keyway.
Adopt technique scheme, drive motor is used for the drives impeller axle and rotates, and in order to realize fixing between impeller shaft and drive motor output shaft, then offers a circular keyway at impeller shaft.
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: 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, and rational in infrastructure, and cost is low, has prolonged working life greatly.
Description of drawings
