Rotary braking energy recovery system

The invention discloses a rotary braking energy recovery system, which is arranged in a rotary system and comprises an oil tank, a main pump, a main valve, a rotary motor and an energy accumulator, the main pump communicates with the oil tank; the main valve is communicated with the main pump; the rotary motor is connected to the main valve; the energy accumulator is connected to the main valve through a rotary energy storage control valve, when the main pump stops supplying energy to the rotary motor through the main valve, the rotary motor starts to brake, and high-pressure oil originally flowing back to the oil tank is recycled to the energy accumulator through the rotary energy storage control valve, namely, the energy accumulator stores energy. 本发明公开了一种回转制动能量回收系统，设置于一回转系统中，其中，回转制动能量回收系统包含：油箱、主泵、主阀、回转马达及蓄能器；主泵连通于油箱；主阀连通于主泵；回转马达连接于主阀；蓄能器通过一回转蓄能控制阀连接于主阀，其中，当主泵停止通过主阀向回转马达供能，回转马达开始制动，将原本流回油箱的一高压油液经回转蓄能控制阀回收至蓄能器，即蓄能器蓄能。
