Circulation pump for auto

Abstract

Vehicle circulating pump includes electromagnetic drive device and leaves, said leaves are installed between the pump shell and the pump cover and are supported on the pump shell by axle, said electromagnetic drive device includes magnet conductor which is supported on the pump shell by axle, the magnet conductor is bound by coil around itself, the soil is connected with the control circuit, the main bulk of said leaves is circular column and is nested out the pump shell, the leaves main bulk and the magnet conductor in the pump shell are composed into inner and outer shrink-fit structure. The present invention has the advantages: good sealing performance, small noise and strong anti-electronic jamming, it avoids the ineffective start of motor, raises the effective power of the engine, reduces energy consumption, and also reduces engine waste gas emissions, it meets the environmental requirements and has long product life to make engine remain the best condition.

Description

technical field

[0001] The invention relates to a pump, in particular to an automobile circulating water pump used for automobile cooling. Background technique

[0002] The automobile engine cooling system is an indispensable system to ensure that the automobile engine does not overheat and the automobile runs normally. The existing automobile engine cooling system is generally driven by an ordinary pump to drive the medium circulation. The pump is driven by the automobile engine. After the engine is turned off, the pump stops working. , so it cannot adapt to a variety of different usage environments.

[0003] The water pump in the automobile engine cooling system requires low noise and no electromagnetic interference due to its operating conditions and environment. The pump transports high temperature, high pressure liquid or semi-liquid medium. Since the pump body and the motor are a whole, it is very difficult to ensure that the medium does not leak into the motor and th...
