美国威格士柱塞泵的产品分类

1.轴向柱塞泵
轴向柱塞泵是活塞或柱塞的往复运动方向与缸体中心轴平行的柱塞泵。轴向柱塞泵是利用与传动轴平行的柱塞在柱塞孔内往复运动所产生的容积变化来进行工作的。由于柱塞和柱塞孔都是圆形零件，加工时可以达到很高的精度配合，因此容积效率高，运转平稳，流量均匀性好，噪声低，工作压力高等优点，但对液压油的污染较敏感，结构较复杂，造价较高。
2.直轴斜盘式柱塞泵
直轴斜盘式柱塞泵分为压力供油型的自吸油型两种。压力供油型液压泵大都采用有气压的油箱，也有液压泵本身带有补油分泵向液压泵进油口提供压力油的。自吸油型液压泵的自吸油能力很强，无需外力供油。靠气压供油的液压油箱，在每次启动机器后，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担任机器，会对液压泵内的与滑鞭造成拉脱现象，出会造成泵体内回程板与压板的非正常磨损。
3.液压柱塞泵
液压柱塞泵靠气压供油的液压油箱，在每次启动机器后，必须等液压渍箱达到使用气压后，才能操作机械。直轴斜盘式柱塞泵分为压力供油型的自吸油型两种。压力供油型液压泵大都采用有气压的油箱，也有液压泵本身带有补油分泵向液压泵进油口提供压力油的。自吸油型液压泵的自吸油能力很强，无需外力供油。对于自吸油型柱塞泵，液压油箱内的油液不得低于油标下限，要保持足够数量的液压油。液压油的清洁度越高，液压泵的使用寿命越长。
4.径向柱塞泵
径向柱塞泵可分为阀配流与轴配流两大类。阀配流径向柱塞泵存在故障率高、效率低等缺点。上70、80年代发展的轴配流径向柱塞泵克服了阀配流径向柱塞泵的不足。由于径向泵结构上的特点，陕定了轴配流径向柱塞泵比轴向柱塞泵耐冲击、寿命长、控制精度高。变量行程短泵的变量是在变量柱塞和限位柱塞作用下，改变定子的偏心距实现的，而定于的zui大偏心距为 5—9mm（根据排量大小不同），变量行程很短。且变量机构设计为高压操纵，由控制阀进行控制。故该泵的响应速度快。径向结构设计克服了如轴向柱塞泵滑靴偏磨的问题。使其抗冲击能力大幅度提高。

VICKERS柱塞泵420系列简介：

 VICKERS柱塞泵420系列工程机械泵是开式回路，轴向柱塞设计，提供许多种控制器使泵具有和每一种用途相匹配的能力。泵控制器的效率允许降低了对系统冷却的要求。允许采用更小巧和并不昂贵的设计，换句话说，保持制冷量不变，而系统的流量增大，于是改善了性能和用户的满意度。

    VICKERS柱塞泵420系列经过严格考验的旋转系允许泵的连续工作压力至 280bar (4000 psi)，间歇工作压力至 320 bar (4600 psi)，而且维护成本低。重型轴承和刚性驱动轴使泵的B10轴承寿命在额定工程机械工况下达到 3320 小时，降低使用成本，延长使用寿命。

    VICKERS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。

    柱塞在缸体中要往复运动，因此，它的运动量很大，在工作过程中需要承受巨大的摩擦力，因此，柱塞要求高的硬度、耐磨性和使用寿命以及高的精度等。通过研究，采用淬火热处理可以满足柱塞的技术要求。
