A11VO190DRG/11L-VZD12N00-S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。

同时膨胀阀出口压力过低，相应的蒸发压力和温度也过低。造成蒸发速度减慢，单位容积（时间）制冷量下降，制冷效率降低。相当一部分的蒸发器未能充分发挥其效能，造成制冷量不足，降低了制冷效果。如果热力膨胀阀开启过大，制冷剂通过的流量就多，即热力膨胀阀向蒸发器的供液量大于蒸发器负荷，使液体制冷剂蒸发过剩，会造成部分液体制冷剂来不及在蒸发器内蒸发，同气态制冷剂一起被吸入压缩机，引起压缩机的湿冲程（液击），使压缩机不能正常工作，造成一系列工况恶劣，甚至冲缸损坏压缩机的事故。
