A11VO190EP2/11R-NPD12N00H-S柱塞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。

在调节开启压力时，下列几点应加以注意：当介质压力接近开启压力（达到开启压力的9%以上）时，不应旋转调整螺杆，以免阀瓣跟着旋转，而损伤密封面。为保证开启压力值准确，调整时用的介质条件，如介质种类、介质温度，应尽可能接近实际工作条件。介质种类改变，特别是从液相变为气相时，开启压力常有所变化。工作温度提高时，开启压力则有所降低。故在常温下调整而用于高温时，常温下的整定压力值应略大于要球的压力值。排放压力和回座压力的调整开启压力调整好以后，若排放压力或回座压力不符合要求，则可以利用阀座上的调节圈来进行调整。
