Problems solved by technology

Since the pump body and the motor are integrated, it is very difficult to ensure that the medium does not leak into the motor and the circuit control board, especially under high temperature and high pressure liquid conditions, and the existing pumps cannot meet this requirement
Since the water pump needs to be driven by a motor, and the general motor structure has a commutator and a brush, the wear is fast due to frictional contact during use, and the service life is short

Embodiment Construction

[0020] The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.

[0021] As shown in Figure 1, the automobile circulation pump includes an electromagnetic drive mechanism and an impeller rotor 12. The impeller rotor 12 is placed in the space composed of the pump casing and the pump cover. The pump casing 3 and the pump cover 1 are fixed by screws 11. On the pump cover 1 With a water inlet 101 and a water outlet 102, the impeller rotor 12 is supported on the pump casing 3 by the shaft 9 through the bearing 10, and the outer end of the shaft 9 is limited by the gasket 2 and the circlip 13.

[0022] The electromagnetic drive mechanism includes a silicon steel sheet 8 wound on a coil 4 and supported by a shaft 9 in the center of the pump casing 3 .

[0023] The impeller rotor 12 is made of magnetic material, and its main body is a cylinder, which is sleeved outside the pump casing 3, and the corresponding silic...

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...
