Gravitational potential energy recovery hydraulic system and excavator
The invention discloses a gravitational potential energy recovery hydraulic system and an excavator. The gravitational potential energy recovery hydraulic system comprises an oil tank; when pressure oil is introduced into the first oil cavity, the heavy object is lifted, and when pressure oil is introduced into the second oil cavity, the heavy object descends; a hydraulic pump; the energy-saving valve comprises a first oil port connected with the second oil cavity and a second oil port connected with the oil tank, the hydraulic control end is communicated with an energy-saving pipeline between the first oil port and the second oil cavity, the first oil port and the second oil port are disconnected at the first valve position, the first oil port and the second oil port are connected through a throttling hole at the second valve position, and the first oil port and the second oil port are connected through a throttling hole at the third valve position. The first oil port is communicated with the second oil port; the reversing valve is provided with a third oil port connected with the first oil cavity, a fourth oil port connected with the second oil cavity, a fifth oil port connected with the oil tank, a sixth oil port connected with the first oil port and a seventh oil port connected with the hydraulic pump, and at the fifth valve position, the third oil port is communicated with the sixth oil port, and the fourth oil port is communicated with the seventh oil port.
本发明公开一种重力势能回收液压系统和挖掘机，重力势能回收液压系统包括：油箱；液压缸，当第一油腔通入压力油时，重物提升，当第二油腔通入压力油时，重物下降；液压泵；节能阀，包括与第二油腔连接的第一油口、与油箱连接的第二油口，液控端与第一油口和第二油腔之间的节能管路连通，在第一阀位，第一油口和第二油口断开连接，在第二阀位，第一油口和第二油口通过节流孔连接，在第三阀位，第一油口和第二油口连通；换向阀，具有与第一油腔连接的第三油口、与第二油腔连接的第四油口、与油箱连接的第五油口、与第一油口连接的第六油口和与液压泵连接的第七油口，在第五阀位，第三油口与第六油口连通且第四油口与第七油口连通。
