A11VLO190DRS/11L-NSD12N00-S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。

制冷的回气管怎么会结霜?在什么情况下会结霜?必须用科学的伦理和逻辑来说明这个问题。家用空调以R22制冷剂为例，它在度时的饱和表压为.399MPa，当此压力低于度的对应温度后，也就是水的结晶点(凝固点)了，管子外表面当然就会先结露后结霜的，这是正常的物理反应和变化。所以家用空调的低压压力低于.399MPa以后，连接管就会开始结霜了。家用冰箱冰柜所用的制冷剂是RR134R6a等，当R12制冷剂的饱和压力低于2.11kg，R134a制冷剂的饱和压力低于.193MPa，R6a制冷剂的饱和压力低于.58MPa表压后，其饱和温度都在度或以下了，当温度在度以下时，如果此时系统加多了制冷剂，蒸发器里的制冷剂不能充分被换热(吸热)产生沸腾(蒸发)，回气过热度过小，液体制冷剂就会进入回气管，甚至压缩机里，必然会造成回气管甚至压缩机的结霜现象。
