Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic motor pumps, in particular to a hydraulic system motor pump. Background Art

[0002] The hydraulic pump motor is a device in construction machinery that converts mechanical energy into hydraulic energy. The working principle of the hydraulic motor pump mainly involves the electric motor, hydraulic pump and hydraulic system, as well as the interaction between these components. The speed of the motor determines the output flow of the hydraulic pump, and the flow affects the working efficiency and performance of the hydraulic system. Therefore, adjusting the working state of the motor is very important for the operation of the hydraulic system.

[0003] The prior art discloses patent application number "CN202221656826.X", a new type of electric hydraulic pump, including an electric hydraulic pump body and a control pedal, wherein the two side surfaces of the control pedal are provided with a cavity, and the interior of the cavity is slidably connected with a telescopic leg, and a support is welded to the bottom surface of one end of the telescopic leg, a limiting groove is provided on the inner wall of the cavity, and the interior of the limiting groove is slidably connected with a limiting block, and one end of the limiting block is welded to the outer wall of the telescopic leg.

At the same time, the hydraulic motor pump is exposed to the outside world, which makes the protection effect of the hydraulic motor pump poor, thereby affecting the stability and safety of the hydraulic motor pump during use, which is not conducive to the use of the hydraulic system motor pump.
