The invention discloses an electric oil pump. The electric oil pump comprises a pump body and a driving motor, blades inside the pump body are fixedly connected with an output shaft of the driving motor, a movable hole allowing the output shaft to penetrate through is formed in one end, close to the driving motor, of the pump body, and the inner diameter of the movable hole is larger than the diameter of the output shaft; and the output shaft is rotationally connected with an inner sealing sheet and an outer sealing sheet, the inner sealing sheet and the outer sealing sheet are tightly sealedand abutted against the inner wall and the outer wall of the pump body correspondingly, the inner wall of the pump body is in a spherical shape, the surface, close to the movable hole, of the inner sealing sheet is in a spherical shape, the edge of one end, close to the outer sealing sheet, of the movable hole is provided with a spherical sealing surface, the surface, close to the pump body, of the outer sealing sheet is of a spherical surface, the pump body is rotationally connected with the output shaft through the inner sealing sheet and the outer sealing sheet, the pump body can rotate inany direction relative to a shell of the driving motor, so that orientation of a liquid inlet pipe and a liquid outlet pipe is adjusted, the liquid inlet pipe and the liquid outlet pipe can be mutually staggered with other objects in the installation space, and an external pipeline can be normally connected to the liquid inlet pipe and the liquid outlet pipe.
Description
technical field [0001] The invention relates to the technical field of fluid delivery, in particular to an electric oil pump. Background technique [0002] An oil pump is a device used to transport oil, usually including a pump body and a drive motor. The output shaft of the drive motor is fixedly connected to the blades inside the pump body. The pump body is provided with a liquid inlet and a liquid outlet. The distance between the outlet and the center axis of the blade rotation is smaller than the distance between the liquid outlet and the center axis of the blade rotation. When the drive motor is running, the blade circulates through the liquid inlet and the liquid outlet and generates hydraulic pressure at the liquid inlet and the liquid outlet. Poor, the hydraulic pressure at the liquid inlet is lower than the hydraulic pressure at the liquid outlet, so that the liquid inlet continues to suck oil, and the liquid outlet continues to output oil. [0003] The drive motor...
