HYDRAULIC SYSTEM OF WIRE SAW MACHINE AND WIRE SAW MACHINE

WIPO Patent Application WO/2023/035365

A1

A hydraulic system of a wire saw machine and a wire saw machine are disclosed. The hydraulic system of a wire saw machine comprises a hydraulic pump (2), a priority flow distribution valve (6), a first hydraulic motor (9), a second hydraulic motor (10), and an oil drain port (D). The priority flow distribution valve comprises a first oil inlet (61), a first oil outlet (62), and a second oil outlet (63), the first oil outlet is configured to output a constant flow, the second oil outlet is configured to output the remaining flow, the first oil inlet is connected to the hydraulic pump, the first oil outlet is connected to the second hydraulic motor, and the second oil outlet is connected to the first hydraulic motor. According to the hydraulic system of a wire saw machine, the flow distributed to the first hydraulic motor, the second hydraulic motor, and other actuators is more stable by providing the priority flow distribution valve, so that the rotating speed of the wire saw is stable. Compared with existing single-pump driven hydraulic systems, the cutting efficiency and operation safety of the wire saw machine are improved.
