蓄能器卸压自动截止装置原理及应用宋锦春刘立鹏吴淑琴刘云亮１前言在液压传动系统中，利用蓄能器构成系统保压回路的应用比较常见，如机床的卡紧装置或工程机械的举升装置。蓄能器保压回路的优点是它允许液压泵电机停止运行而仍能保证系统执行器有恒定压... Accumulator pressure relief automatic cut-off device principle and application Songlian Chun LIU Li-peng Wu Shuqin  Liu Yunliang 1 Foreword In the hydraulic drive system, the use of accumulators to form the system pressure retaining circuit is relatively common, such as machine tool card Tightening device or construction machinery lifting device. The advantage of the accumulator packing circuit is that it allows the hydraulic pump motor to stop operating while still ensuring that the system actuator has a constant pressure ...
