Excavator boom flow regeneration and potential energy recovery energy-saving device
The invention discloses an excavator movable arm flow regeneration and potential energy recovery energy-saving device which comprises a load-sensitive hydraulic pump, a pilot control valve block, a main control valve block and a movable arm oil cylinder and further comprises three working oil ports formed in the outer portion of the energy-saving device. The energy-saving device internally comprises a four-port hydraulic transformer, a servo motor, a one-way valve, a valve plate, a normally-closed electromagnetic valve, a normally-open electromagnetic valve, an energy accumulator and a pressure sensor. The excavator movable arm flow regeneration and potential energy recovery energy-saving device based on the four-port hydraulic transformer has the advantages that according to pressure values measured by all the pressure sensors, the controller controls the corresponding electromagnetic valves to act, the energy-saving device is switched into a hydraulic loop, the servo motor is adjusted through the controller, and the energy-saving effect of the excavator movable arm flow regeneration and potential energy recovery energy-saving device is achieved. A control angle of a valve plate of the four-port hydraulic transformer is changed, so that the transformation ratio of the four-port hydraulic transformer is changed, and hydraulic energy converted from gravitational potential energy in the descending process of the movable arm of the excavator is stored in the energy accumulator.
本发明公开了一种挖掘机动臂流量再生和势能回收节能装置，包括负载敏感液压泵，先导控制阀块，主控制阀块，及动臂油缸，还包括节能装置的外部设有三个工作油口，节能装置内部包括四口液压变压器、伺服电机、单向阀、配流盘、常闭电磁阀、常开电磁阀、蓄能器、压力传感器；优点在于：本发明提出了一种基于四口液压变压器的挖掘机动臂流量再生和势能回收节能装置，根据各压力传感器测得的压力值，通过控制器控制相应的电磁阀动作，将本发明的节能装置切入液压回路，并通过控制器调节伺服电机，改变四口液压变压器配流盘的控制角，从而改变其变压比，使挖掘机动臂下降过程中重力势能转换的液压能储存到蓄能器中。
