Embodiment Construction

[0034] Please refer to figure 1 As shown, it shows the specific structure of the preferred embodiment of the present invention, including a pump casing 10 , a pump head 20 , a casing 30 , a rotor 40 and a stator 50 .

[0035] The pump head 20 is installed on one end surface of the pump casing 10 and forms a pump cavity 101 surrounded by the pump casing 10. A shaft core 60 is fixed inside the pump cavity 101. The inner end of the shaft core 60 is fixedly connected with the pump casing 10. The pump head 20 is provided with a water inlet 21 and a water outlet 22 , the water inlet 21 and the water outlet 22 are connected to the pump chamber 101 , and the shaft core 60 is axially facing the water inlet 21 .

[0036] The casing 30 is installed on the other end surface of the pump casing 10 and forms a closed accommodating chamber 102 with the pump casing 10 .

[0037] The rotor 40 is located in the aforementioned pump cavity 101, one end of the rotor 40 is rotatably mounted on the ...

Abstract

The invention discloses an electronic water pump for an automobile. The electronic water pump for the automobile comprises a pump case, a pump head, an outer shell, a rotor and a stator. The pump head is mounted on one end face of the pump case, and a pump cavity is formed through enclosure of the pump head and the pump case. The outer shell is mounted on the other end face of the pump case, and an airtight accommodating cavity is formed through the enclosure of the outer shell and the pump case. The rotor is located in the pump cavity. The stator is fixed in the accommodating cavity and surrounds the rotor. A static sealing ring is arranged between the pump head and the pump case to form a static sealing structure so that a water channel in the pump cavity can be completely isolated from the stator, and the design of a traditional dynamic mechanical sealing structure is substituted. As a result, on one hand, performance loss caused by resistance generated by dynamic mechanical sealing friction in a working process of the electronic water pump can be eliminated effectively, and the efficiency of the electronic water pump is improved; on the other hand, the situation that a water leakage fault happens because the service life of a mechanical sealing piece is shortened due to the abrasion of the mechanical sealing piece can be eliminated effectively, and therefore the reliability of the electronic water pump is improved.

Description

technical field [0001] The invention relates to the technology in the field of auto parts, in particular to an automotive electronic water pump. Background technique [0002] A pump is a machine that transports or pressurizes a liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali, emulsions, suspoemulsions and liquid metals, etc., and can also transport liquid and gas mixtures. and liquids containing suspended solids. [0003] Many new energy vehicles, RVs and other special vehicles are often used in miniature water pumps as water circulation, cooling or on-board water supply systems. Such miniature self-priming water pumps are collectively referred to as automotive water pumps. However, the current automotive electronic water pump generally adopts the design of dynamic mechanical seal structure, which makes it i...
