Abstract
The utility model discloses an electronic water pump for a vehicle. The electronic water pump comprises a pump cover, a pump body, a fixed seat and a pump seat, wherein a direct current brushless motor is arranged in the pump body, and a water pump blade and a rotor of the direct current brushless motor are made into a whole through injection molding. The electronic water pump has the advantages that the assembly is simple, the reliability is high, and the service life is long.
Description
Technical field
The utility model relates to a kind of auto electronic water pump.
Background technique
Existing auto pump all adopts the rotation of brush direct current motor impeller, adopts motive sealing between motor shaft and pump case.This sealing means, liquid leaks easily, causes water pump low working life, has increased maintenance and maintenance cost.
The model utility content
The utility model purpose is to provide a kind of auto electronic water pump at the defective that prior art exists.
The utility model adopts following technological scheme for achieving the above object:
The utility model auto electronic water pump comprises pump cover, the pump housing, fixed base and pump seat, in the described pump housing dc brushless motor is set, and water pump blade and dc brushless motor rotor are made of one by injection moulding.
The pumping hole protective cover also is set on the described pump cover.
The O RunddichtringO is set between described pump cover and the pump housing, and fixes by screw.
Described dc brushless motor is fixed in the pump housing by the fixing rod assembly, and seals by ultrasonic welding.
Simple, high, the long service life of reliability of the utility model assembling.
Description of drawings
Fig. 1: the utility model structural representation.
Embodiment
