A11VO260LRDU2/11R-NZD12N00P油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。

制冷剂泄露【故障分析】系统中制冷剂泄漏后，制冷量不足，吸、排气压力低，膨胀阀处能听到比平时大得多的断续的吱吱气流声。蒸发器不挂霜或挂较少量的浮霜，若调大膨胀阀孔，吸气压力仍无大变化。停机后，系统内平衡压力一般低于相同环境温度所对应的饱和压力。【排除方法】制冷剂泄漏后，不能急于向系统内充灌制冷剂，而应立即查找渗漏点，经修复后再充灌制冷剂。维修后充灌制冷剂过多【故障分析】维修后的制冷系统中充灌的制冷剂量过系统的容量，制冷剂就会占去冷凝器一定的容积，减少散热面积，使其制冷效率降低，出现吸、排气压力普遍高于正常的压力值，蒸发器结霜不实，降温慢。
