节能液压机
摘要：
本发明涉及一种液压机，主要包括：由上横梁、下横梁和两侧立柱构成的机身；主油缸和两个侧油缸；滑块；工作台；液压垫油缸；的液压垫；由提升液压油路、加压液压油路、液压垫油缸的液压油路、滑块能量储存再利用液压油路组成的液压系统；以及电气控制系统。其特点是：在液压系统中增加了由一个放大缸、一套蓄能器组、两个插装阀、两个二位三通换向阀、两个溢流阀、两个三位四通换向阀、一个位移传感器、两个行程开关(或位移传感器)、两个压力传感器组成的滑块能量储存再利用液压油路。其优点是：可使原来通过插装阀泄放到油箱的带压油液得以循环再利用，大大降低了电能消耗，提高了液压机的能效，可节能20-50%，同时还提高了液压机滑块的上行速度，降低系统的发热量。
摘要（英）：

The invention relates to a hydraulic machine. The hydraulic machine mainly comprises a machine body composed of an upper cross beam, a lower cross beam and stand columns on the two sides, a main oil cylinder, two side oil cylinders, a sliding block, a workbench, hydraulic pad oil cylinders, a hydraulic pad, a hydraulic system and an electric control system, wherein the hydraulic system is composed of a lifting hydraulic oil way, a pressurizing hydraulic oil way, a hydraulic oil way of the hydraulic pad oil cylinder and a sliding block energy storage and reutilization hydraulic oil way. The hydraulic machine is characterized in that the sliding block energy storage and reutilization hydraulic oil way composed of an amplifying cylinder, an energy accumulator set, two cartridge valves, two two-position three-way reversing valves, two overflow valves, two three-position four-way reversing valves, a displacement sensor, two travel switches (or displacement sensors) and two pressure sensors is additionally arranged in the hydraulic system. The hydraulic machine has the advantages that pressure oil which is originally drained to an oil tank through a cartridge valve can be recycled, electric energy consumption is greatly lowered, energy efficiency of the hydraulic machine is improved, and energy can be saved by 20-50%; and meanwhile, the upward traveling speed of the hydraulic machine sliding block is further increased, and the system heat productivity is lowered.
