Hydraulic system, breaking hammer, pile hammer and rammer
The invention provides a hydraulic system, a breaking hammer, a pile hammer and an earth rammer. The hydraulic system comprises a hydraulic oil tank; a hydraulic pump; a first working cavity takes gas as a working medium of the first working cavity, and a second working cavity takes hydraulic oil as a working medium of the second working cavity; the oil inlet valve is configured to control connection and disconnection of the first oil inlet and the first oil outlet according to the pressure of the first oil inlet and the pressure of the first control port so as to control whether the hydraulic oil tank supplies oil to the second working cavity or not; the oil outlet valve is configured to control connection and disconnection of the second oil inlet and the second oil outlet according to the pressure of the second oil inlet and the pressure of the second control port so as to control whether the second working cavity returns oil to the hydraulic oil tank or not; and the energy storage device is configured to supplement the hydraulic oil to the second working cavity in the oil inlet state of the second working cavity and absorb the hydraulic oil from the second working cavity in the oil outlet state of the second working cavity, so that the flow of the hydraulic oil in the second working cavity is kept stable.
本公开提供了一种液压系统、破碎锤、打桩锤和夯土机。液压系统包括：液压油箱；液压泵；油缸，第一工作腔将气体作为第一工作腔的工作介质，第二工作腔将液压油作为第二工作腔的工作介质；进油阀，被配置为根据第一进油口的压力和第一控制口的压力控制第一进油口和第一出油口的通断，以控制液压油箱是否向第二工作腔供油；出油阀，被配置为根据第二进油口的压力和第二控制口的压力控制第二进油口和第二出油口的通断，以控制第二工作腔是否向液压油箱回油；和蓄能装置，被配置为在第二工作腔进油的状态向第二工作腔补充液压油和在第二工作腔出油的状态从第二工作腔吸收液压油，以使第二工作腔的液压油的流量保持稳定。
