Abstract

The invention discloses an energy recovery system for a passive volume synchronous system. The energy recovery system comprises energy accumulator energy recovery oil ways, energy accumulator oil supply oil ways and an energy accumulator oil supplementing oil way and is used for the passive volume synchronous system. Hydraulic energy in leveling control cylinders is recovered through an energy accumulator. The energy accumulator energy recovery oil ways and the energy accumulator oil supply oil ways are connected between the energy accumulator and the leveling control cylinders. The hydraulic energy of oil liquid in the leveling control cylinders is stored through the energy accumulator energy recovery oil ways in the descending stage of a working beam. The leveling control cylinders are driven by the hydraulic energy stored by the energy accumulator to work synchronously by means of the energy accumulator oil supply oil ways in the ascending stage of the working beam, and hydraulic oil is supplemented to the energy accumulator through the energy accumulator oil supplementing oil way. The energy recovery system has the good energy saving effect and is high in control precision and capable of lowering working energy consumption of a large hydraulic synchronous system.

Description

technical field [0001] The invention relates to a hydraulic system, in particular to an energy recovery system of a passive volume synchronization system. Background technique [0002] With the rapid development of industry and the increasing application of hydraulic technology in the engineering field, the load capacity of large equipment continues to increase, and the traditional single-actuator drive method can no longer meet the requirements of modern manufacturing. Rigid synchronous drives of hydraulic cylinders are widely used in industrial fields due to the characteristics of low weight-to-power ratio of hydraulic components, high power density, convenient pipeline layout, and easy automation control. [0003] With the increasing shortage of energy, more and more people pay more and more attention to the energy-saving performance of the multi-hydraulic cylinder rigid synchronization system used in the high-power transmission system. During the working process, the pr...
