力士乐柱塞泵A10VSO71DR/31R-PKC94N00现货

REXROTH力士乐轴向柱塞泵与径向柱塞泵比较，排出压力高，它一般可在20～50MPa范围内工作，效率也高，径向尺寸小、结构紧凑、体积小、重量轻。但结构较径向柱塞泵复杂，加工制造要求高，价格较贵。轴向柱塞泵一般用于机床、冶金、锻压、矿山及起重机械的液压传动系统中，特别广泛地应用于大功率的液压传动系统中。为了提率，在应轴向柱塞泵一般都由缸体、配油盘、柱塞和斜盘等主要零件组成。力士乐柱塞泵工作原理缸体内有多个柱塞，柱塞是轴向排列的，即柱塞的中心线平行于传动轴的轴线，因此称它为轴向柱塞泵。但它又不同于往复式柱塞泵，因为它的柱塞不仅在泵缸内做往复运动，而且柱塞和泵缸与斜盘相对有旋转运动。柱塞以一球形端头与斜盘接触。在配油盘上有高低压月形沟槽，它们彼此由隔墙隔开，保证一定的密封性，它们分别与泵的进油口和出油口连通。斜盘的轴线与缸体轴线之间有一倾斜角度。

柱塞泵：A4VSO、A10VSO、A2FO，定量马达：A2FM，A4FM，A10FM/E， 齿轮泵：0510、AZPF，叶片泵：PV7

直轴斜盘式柱塞泵分为压力供油型和自吸油型两种。压力供油型液压泵大都是采用有气压的油箱，靠气压供油的液压油箱，在每次启动机器之后，必须等液压渍箱达到使用气压后，才能操作机械。如液压油箱的气压不足时就启动机器，会对液压泵内的与滑靴造成拉脱现象，出会造成泵体内回程板与压板的非正常磨损。
