HYDRAULIC SYSTEM FOR THREE-DIMENSIONAL GARAGE

摘要

Disclosed is a hydraulic system for a three-dimensional garage, comprising a power unit (1), a control unit (2), an execution unit (3) and an energy storage unit (4). The power unit (1) comprises two motor oil pumps (11) in parallel. The control unit (2) comprises two control solenoid valve sets (21) in parallel. The execution unit (3) comprises a hydraulic cylinder (31). The energy storage unit (4) comprises an energy storage pot (41). The output ends of the motor oil pumps (11) are connected to the energy storage pot (41) and the input ends of the control solenoid valve sets (21). Stop valves (43) are arranged at pressure input and output ends of the energy storage pot (41). The motor oil pumps (11) in parallel are adopted in the power unit (1) of the hydraulic system, and the control solenoid valve sets (21) in parallel are adopted in the control unit. When one set of system fails, the set of system will be instantly switched to the other set of system so as to provide power, and the energy storage unit (4) is added as a standby power source, so as to guarantee a non-interrupted power output and the operation safety of the garage.
