A11VO60DRG/10+A2FO16/61柱塞油泵河北唐山柱塞泵的工作原理

   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q=65MPa时,随着粗糙度等级的越来越高,渗透量迅速减小,也就是说在q4MPa时,在同样一个渗漏量等级,粗糙度愈高所需要的q愈小,其轴向力越小真空截止阀。但对于s9MPa密封副材料,在用于3MPa等级的高压阀时,除了高压截止阀从线弹性断裂力学观点出发,[]从强度要求考虑,Ra.5m以上,还要从密封机理上考虑。因此,对于s为9MPa的高压截止阀用密封副,其密封面粗糙度必须在Ra.5m以上。
