Abstract

The invention discloses a pressure regulating gear pump which comprises a motor. The motor is fixedly connected with one end of a pump via a motor fixing plate, and the other end of the pump is provided with a pump cover. An output shaft of the motor is connected with a bearing insert in the pump via a pair of transmission parts. A lower baffle and an upper baffle are arranged in the pump, a driving gear and a driven gear which are meshed with each other are arranged between the lower baffle and the upper baffle and in a gear cover, the driving gear is connected with a driving shaft, and the driven gear is connected with a driven shaft. A decompressing groove is arranged at an inner hole of the gear cover to realize pressure regulation function.

Description

technical field [0001] The invention relates to a gear pump, in particular to a pressure regulating gear pump. Background technique [0002] Existing gear pumps generally do not have a pressure regulating function. The transmission parts of the gear pump generally need to be molded into two at a time. During the use of this kind of transmission parts, the combination between the two transmission parts is not enough. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pressure regulating gear pump, which can realize the pressure regulating function. [0004] In order to solve the above technical problems, the technical solution of the pressure regulating gear pump of the present invention is: [0005] Including the motor 2, the motor 2 is fixedly connected with one end of the pump body 8 through the motor fixing plate 3, and the other end of the pump body 8 is provided with a pump cover 20; the output shaft of the...
