威格士柱塞泵工作原理
一、径向柱塞泵
径向柱塞泵是将柱塞径向排列在缸体内，缸体由原动机带动连同柱塞一起转动，周期性改变密闭容积的大小，达到吸、排油的目的。
二、轴向柱塞泵
1结构和原理
轴向柱塞泵是将多个柱塞轴向配置在一个共同缸体的圆周上，并使柱塞中心线和缸体中心线平行的一种泵，轴向柱塞泵有两种形式，直轴式（斜盘式）和斜轴式（摆缸式），所示的为直轴式轴向柱塞泵的工作原理，这种泵主要由缸体1、配油盘2、柱塞3和斜盘4组成。柱塞沿圆周均匀分布在缸体内。斜盘与缸体轴线倾斜一角度γ，柱塞靠机械装置或低压油作用下压紧在斜盘上，配油盘2和斜盘4固定不转，当原动机通过传动轴使缸体转动时，由于斜盘的作用，迫使柱塞在缸体内作往复运动，并通过配油盘的配油窗口进行吸油和压油。回转方向，当缸体转角在π～2π范围内，柱塞向外伸出，柱塞底部的密封工作容积增大，通过配油盘的吸油窗口吸油；在0～π范围内，柱塞被斜盘推入缸体，使密封容积减小，通过配油盘的压油窗口压油。缸体每转一周，每个柱塞各完成吸、压油一次，如改变斜盘倾角γ，可改变液压泵的排量，改变斜盘倾角方向，就能改变吸油和压油的方向，成为双向变量泵。

 VICKERS威格士柱塞泵规格齐全有多达9 种，主要是直轴式变量泵，控制方式多样化，主要靠压力来控制变量。提高工作灵活性，提供流量补偿。 威格士柱塞泵运行噪声很低，能满足当今要求苛刻的工业条件。每台泵的噪声级接近于或低于驱动该泵电动机的噪声，噪声是的定时配置来降低的，而该措施还使输出流量中压力“脉动”很小。

威格士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。带滑靴结构的轴向柱塞泵是目前使用最广泛的轴向柱塞泵，安放在缸体中的柱塞通过滑靴与斜盘相接触，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，完成吸排油过程。柱塞与缸孔组成的工作容腔中的油液通过配油盘分别与泵的吸、排油腔相通。变量机构用来改变斜盘的倾角，通过调节斜盘的倾角可改变泵的排量。
