Abstract

The invention discloses a hot oil pump. The hot oil pump comprises a pump body, a pump cover, a bearing pedestal, a coupling, a motor and a base. The pump body, the pump cover, the bearing pedestal and the coupling are fixedly connected in sequence. The pump body and the motor are fixedly connected with the base. An impeller and a pump shaft are arranged in the pump body. An acorn nut is arranged at the front end of the impeller. The impeller is fixedly connected with the pump shaft through the acorn nut. A motor shaft is arranged at on end of the motor. The motor shaft is in transmission connection with the motor. The pump shaft is in transmission connection with the motor shaft through the coupling. A filler pressing ring is arranged in the pump cover. The hot oil pump is simple in structure, small in size, good in performance and reliable in use, and operation cost is saved.

Description

technical field [0001] The invention relates to the technical field of a pump body, in particular to a thermal oil pump. Background technique [0002] The thermal oil pump is an ideal thermal oil circulation pump or heat transfer pump, and is an ideal supporting pump for heat exchange equipment. The thermal oil pump adopts a self-heating and heat dissipation structure, which changes the traditional water cooling structure and makes the structure simple. It is small in size, saves operating costs, good in performance and reliable in use. It is the second-generation product developed on the basis of our country's digestion and absorption of foreign oil pumps. The basic structure is a single-stage single-suction cantilever-type foot support structure, and the pump inlet is axial suction. , with the outlet as the center and vertically upward, and mounted on the base together with the motor. The support of the hot oil pump adopts the structural form of double-end ball bearing su...
