A11VO190DRS+A11VO190DRGX柱塞液压泵河北秦皇岛柱塞泵的工作原理

   柱塞泵是液压系统的一个重要装置。它依靠柱塞在缸体中往复运动，使密封工作容腔的容积发生变化来实现吸油、压油。柱塞泵具有额定压力高、结构紧凑、效率高和流量调节方便等优点，被广泛应用于高压、大流量和流量需要调节的场合，诸如液压机、工程机械和船舶中。

   柱塞泵是往复泵的一种，属于体积泵，其柱塞靠泵轴的偏心转动驱动，往复运动，其吸入和排出阀都是单向阀。当柱塞外拉时，工作室内压力降低，出口阀关闭，低于进口压力时，进口阀打开，液体进入;柱塞内推时，工作室压力升高，进口阀关闭，高于出口压力时，出口阀打开，液体排出。当传动轴带动缸体旋转时，斜盘将柱塞从缸体中拉出或推回，完成吸排油。

度整体的测量准确度要求？在某一特定流量下使用，还是在某*量范围内使用？在什么测量范围内保持上述度？其度能保持多久？是否易于重新校验？是否要现场在线核对仪表度？这些问题必须细致考虑。重复性重复性在过程控制应用中是重要的指标，有仪器本身原理与制照质量所决定，而度除取决于重复性外，还与量值系统有关。线性度流量仪表输出主要有线性和平方根非线性两种。上限流量、下限流量和流量范围选择流量仪表的口径应按被测管道使用的流量范围和被选仪表的上限流量和下限流量来选配，而不是简单地按管道通径配用。
