Embodiment Construction
[0010] The method for setting the manipulator rotation structure of the hydraulic system according to the embodiment of the present invention, its main steps include:
[0011] (1) First, add a valve control circuit between the variable pump and the hydraulic cylinder, in which a hydraulic control reversing valve is installed, and a swing motor is installed inside the manipulator rotating hydraulic system;
[0012] (2) Then, a check valve and a relief valve are added to the oil circuit connected to the periphery of the motor. When the electromagnetic reversing valve returns to the neutral position, due to the unbalanced pressure at both ends of the cycloidal motor, when the pressure at the left end is high, it will pass through the check valve. return valve and relief valve to the fuel tank;
[0013] (3) Three-position four-way one-way valve is selected as the one-way valve, and additional one-way valve and relief valve can be used to achieve hydraulic motor locking and oil buf...
