Embodiment Construction
[0011] The speed regulation method of the hydraulic system transmission mechanism described in the embodiment of the present invention, its main steps include:
[0012] ⑴Install and determine the hydraulic actuators, the direction control is realized by the reversing valve or logic control unit, adopt the logical combination structure of the cartridge valve and the pilot control valve, the speed control is by changing the flow rate of the input or output of the hydraulic actuators or using the sealed space volume change to achieve;
[0013] ⑵Adopt quantitative pump to supply oil, use flow control valve to change the flow rate of input or output hydraulic actuator to adjust speed, and then, change the displacement of hydraulic pump or hydraulic motor to achieve the purpose of speed regulation;
[0014] (3) The volumetric throttling speed regulation adopts the variable pump to supply oil, and the flow control valve is used to adjust the flow rate of the input or output hydraulic...
