ENERGY RECYCLING SYSTEM FOR WORKING DEVICE

摘要

An energy recycling system for a working device comprises an energy converter, a pressure-retaining valve, a switching valve, an energy collector, a logic control unit, a main valve, a movable arm device and corresponding connecting components. By using this system, the potential energy generated during the lowering of the movable arm device can be controllably converted into hydraulic energy to be stored in the energy collector, and the potential energy can also be directly recycled for acting on the movable arm device in a balancing mode. The heat generated by the hydraulic system is thereby reduced, the input power of a prime motor is reduced, and the purpose of saving energy is achieved.
