Title:
HYDRAULIC CONTROL SYSTEM AND MECHANICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/116567
Kind Code:
A1
Abstract:
A hydraulic control system and a mechanical device. The hydraulic control system comprises a pump (300), a first apparatus (100), a second apparatus (200), and a backflow control apparatus (400). The pump (300) comprises an output channel (310) to output a fluid; the first apparatus (100) is connected to the output channel (310) to perform a work operation under the drive of the fluid output by the pump (300); the second apparatus (200) is connected to the output channel (310) to perform a work operation under the supply of the fluid output by the pump (300). The backflow control apparatus (400) is connected between the output channel (310) and the first apparatus (100); when the first apparatus (100) performs a first work operation, the first apparatus (100) discharges the fluid, and the backflow control apparatus (400) is turned on to guide the fluid discharged by the first apparatus (100) to the output channel (310) to be supplied to the second apparatus (200). The hydraulic control system can reduce the operation burden of the pump, reduce the power consumption of the pump, and avoid a temperature rise of the fluid of the whole hydraulic control system, thereby avoiding the poor work of the device of the hydraulic control system.
