摘要
简介了液压机的基本组成部分及其一个完整的工作周期的构成。在分析了大中型液压机在一个完整的工作周期内的各个阶段的能量消耗情况的基础上,指出在大中型液压机中开展节能研究的必要性。明确指出针对大中型液压机,可在分散多动力、机械与液压组合式执行元件及交流伺服电动机驱动定量泵的三个途径上开展节能研究,并进一步深入分析了这三种节能方式的工作原理及研究现状。
In this paper, basic composition and whole work period of hydraulic machine are briefly introduced. On the basis of analyzing every stage energy consumption in the whole work period, energy-saving necessity in the me- dium and large hydraulic machine is pointed out. Three ways of energy-saving in the medium ＆ large hydraulic machine are respectively dispersive and many power, combination mechanic transmission with hydraulic transmission, constant delivery pump driven by AC servo motor. The operating principle and research status of three ways of ener- gy-saving are deeply analyzed in this paper.
