Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic motors, in particular to an energy-saving hydraulic motor. Background Art

[0002] A hydraulic motor is an actuator in a hydraulic system. Its main function is to convert the liquid pressure energy provided by the hydraulic pump into mechanical energy. There are various types of hydraulic motors, including gear type, vane type, plunger type, etc. They achieve rotational motion through the action of hydraulic oil.

[0003] Existing hydraulic motors all adjust the driving force for the hydraulic motor output shaft by controlling the delivery power of the power pump according to needs. However, there is an imprecise control by only controlling the delivery power of the delivery pump, and it is impossible to accurately adjust the flow and pressure according to actual needs, resulting in unnecessary energy consumption.

[0004] To this end, we proposed an energy-saving hydraulic motor. Utility Model Content

[0005] The utility model aims to provide an energy-saving hydraulic motor, comprising a hydraulic motor body, an integrated valve body mounting seat is arranged on the side of the hydraulic motor body, a power pump is arranged in the integrated valve body mounting seat, a cartridge throttle valve is detachably mounted on the integrated valve body mounting seat, and the cartridge throttle valve is connected to the output end of the power pump.

[0006] Through the integrated design between the plug-in throttle valve and the power pump, the plug-in throttle valve can be quickly installed and connected to the output end of the power pump, and the output resistance to the power pump can be adjusted through the plug-in throttle valve. Compared with the existing technology, the adjustment method is more precise, and a speed regulating valve can be formed as a whole to achieve the actual required flow rate, thereby adjusting the output power of the hydraulic motor to achieve a balance between the supply side and the demand side, thereby achieving energy-saving effects.

[0007] Furthermore, a motor oil inlet is provided on the hydraulic motor body, and the motor oil inlet is connected to the output end of the power pump.

[0008] Through the above technical solution, the power pump can deliver hydraulic oil to the motor oil inlet on the hydraulic motor body to provide power for the hydraulic motor body.

[0009] Furthermore, a motor oil outlet is provided on the hydraulic motor body, and the motor oil outlet is connected to the input end of the power pump.

[0010] Through the above technical solution, the motor oil outlet returns the hydraulic oil to the input end of the power pump, forming a closed flow loop to continuously provide power to the hydraulic motor body.

[0011] Furthermore, a control pipeline is provided on the power pump.

[0012] Through the above technical solution, the control pipeline can adjust the output power of the power pump.

[0013] Furthermore, a motor oil drain port is provided on the hydraulic motor body.

[0014] Through the above technical solution, when the hydraulic oil in the hydraulic motor leaks, the leaked oil can be discharged through the motor oil drain port to avoid affecting the normal operation of the motor body.

[0015] Furthermore, the plug-in throttle valve cooperates with the control pipeline structure.

[0016] Through the above technical solution, the damping generated by the plug-in throttle valve will flow back into the control pipeline of the power pump, so that a speed regulating valve can be formed as a whole.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] In the utility model, through the integrated design between the plug-in throttle valve and the power pump, the plug-in throttle valve can be quickly installed and connected to the output end of the power pump, and the output resistance to the power pump can be adjusted by the plug-in throttle valve. Compared with the prior art, the adjustment method is more precise, and a speed regulating valve can be formed as a whole to achieve the actual flow rate required, thereby adjusting the output power of the output shaft of the hydraulic motor to achieve a balance between the supply end and the demand end, thereby achieving an energy-saving effect.
