Abstract

The invention relates to an oil pump assembly. The oil pump assembly includes: a pump body, including a pump body support and a pump cover. The pump body support and the pump cover are detachably connected. The cavity is used to accommodate low-pressure oil; the eccentric shaft is rotatably installed on the pump body, the eccentric shaft has an eccentric part, and the eccentric part is located in the oil cavity; the plunger pump is set in the oil cavity, driven by the eccentric shaft and the return spring to pumping oil; the plunger pump is fixedly installed on the pump body support, and there is a high-pressure oil circuit on the pump body support, and the high-pressure oil circuit communicates with the outlet of the plunger pump. Both the plunger pump and the eccentric shaft are arranged on the support of the pump body, and the return spring does not need to be pressed when assembling the pump cover, which makes the assembly more convenient. Accurately locate the relative position of the plunger pump and the eccentric shaft to prevent the oil from being unable to be pumped or the oil not being pumped smoothly due to the incompatibility of the two positions.

Description

technical field [0001] The invention relates to an oil pump assembly. Background technique [0002] Disc spring hydraulic operating mechanism is currently widely used in high-voltage power transmission and transformation systems. The key link in the disc spring hydraulic operating mechanism is to pump hydraulic oil into the high-pressure oil chamber through the oil pump assembly, and obtain high-pressure oil by compressing the disc spring for supply The operating mechanism is used. The structure of the oil pump assembly is shown in the Chinese invention patent with the authorized notification number CN105422410B, which specifically includes a motor, a pump body, an eccentric shaft and a plunger pump located in the pump body, the motor is vertically arranged and located above the pump body, and the eccentric shaft It is coaxially connected with the motor. There is an oil chamber in the pump body. The plunger pump is fixed on the pump body. The piston of the plunger pump is o...
