Beschreibung
Zusammenfassung:A hydraulic system for a rotary machine tool, comprising an oil tank, a main pump, a control valve, and a rotary motor. The oil tank is connected to an oil suction port of the main pump. An oil outlet of the main pump is connected to a port P of a control valve, a port T of the control valve is communicated with the oil tank, and a port A of the control valve and a port B of the control valve are connected to two ends of the rotary motor. The control valve comprises a compensation valve, an electric proportional valve, and an electromagnetic directional valve. The port P is connected to a first oil port of the electric proportional valve, a third oil port of the compensation valve, and a fifth oil port of the compensation valve. A second oil port of the electric proportional valve is connected to a first oil port of the compensation valve. A second oil outlet of the compensation valve is connected to a third oil port of the electromagnetic directional valve and the port T. A fourth oil outlet of the compensat
