Abstract

The utility model relates to an electric oil pump, belonging to the technical field of power machinery structures. The electric oil pump is characterized in that a motor body is mounted in an oil tank (11), a fan (7) and heat radiating fins (9) configured due to an air cooling mode in the prior art are removed, and a layer of explosion suppression surface (10) is designed at the matching part of a motor shell and a motor end cover. According to the electric oil pump, parts of a motor and the oil pump are improved in structure, so that the oil pump and the motor are combined into a whole body, therefore, connecting parts are reduced, the requirement of high coaxiality between the motor and the oil pump is met, and the service life of a motor pump set is prolonged and the running quality of the motor pump set is improved. The fan is removed from the motor, the heat radiating fins are removed from the motor shell, the motor and the oil pump are integrally mounted in the oil tank, and an oil immersion cooling mode is adopted, so that the electric oil pump is safer and more reliable.

Description

Electric oil pump
Technical field
The utility model relates to a kind of electric oil pump, belongs to the dynamic power machine technical field of structures.
Background technique
The Oil pump electrical machinery group of using at present is the compound mode that adopts common electric machine to connect with oil pump; Motor and oil pump are respectively two parts that use separately; Motor is radiating fin and the fan cooled that adopts motor casing, and oil pump is installed in the fuel tank, and motor is installed in the fuel tank outside.This mounting type in use not only requires very high to the coaxality of motor and oil pump, and volume is big, and it is big to take up room, and in the occasion with special usage requirement such as inflammable and explosive, has potential safety hazard to a certain degree.
Summary of the invention
The purpose of the utility model is to solve the deficiency that above-mentioned prior art exists, and provides a kind of simple structural design reasonable, uses safely, and volume is little, and it is little to take up room, electric oil pump with low cost.
The utility model is realized through following technological scheme:
Electric oil pump; Changing existing air cooling way is the oil immersion type of cooling; Its special way is the motor main body is installed in the fuel tank 11, removes the fan 7 and the radiating fin 9 that are provided with because of air cooling way, and with the cooperation place design one deck explosion suppresion surface 10 of motor casing 12 with electric motor end cap 6.
In order further to reduce the volume of electric oil pump, reduce cost, divide the motor shaft 1 of body structure and oil pump shaft 2 merging to be made as the same axis 3 with existing.
In order further to reduce the volume of electric oil pump, reduce cost and save material, the electric motor end cap of existing minute body structure 4 is merged with oil pump end cap 5 be made as same end cap 6.
The utility model is a kind of Oil pump electrical machinery combination of remodeling; Through improving the structure of motor and oil pump component, make oil pump and group of motors synthesize an integral body, reduced coupling; Satisfy the requirement of high-axiality between motor and the oil pump, improved the working life and the ride quality of electric-motor pump group.Motor has removed fan, and motor casing has removed radiating fin, and motor and oil pump integral installation are adopted the immersion oil type of cooling in fuel tank, more safe and reliable.
Description of drawings
Fig. 1: be prior art Oil pump electrical machinery group structural representation;
Fig. 2: the utility model electric oil pump structural representation.
Embodiment
Following with reference to accompanying drawing, provide the embodiment of the utility model, be used for the formation of the utility model is further specified.
Embodiment 1
A kind of latent oily explosion-proof type electric oil pump of present embodiment is merged into the same axis 3 with reference to figure 1,2 with motor shaft 1 and oil pump shaft 2, and electric motor end cap 4 is merged into same end cap 6 with oil pump end cap 5; Motor has removed fan 7; Motor casing 8 has removed radiating fin 9, with electric oil pump as an integral installation in fuel tank 11, adopt the mode of immersion oil cooling to substitute existing air cooling way; Also design explosion suppresion surface 10 simultaneously, satisfied the explosion-proof technical requirements of immersion oil.
Present embodiment is a kind of latent oily explosion-proof type electric oil pump; Through improving the structure of motor and oil pump component, make oil pump and group of motors synthesize an integral body, reduced coupling; Satisfy the requirement of high-axiality between motor and the oil pump, improved the working life and the ride quality of electric-motor pump group.Motor has removed fan, and motor casing has removed radiating fin, and motor and oil pump integral installation are adopted the immersion oil type of cooling in fuel tank, more safe and reliable.

Claims (3)
