下载威格士液压泵特点 威格士油泵结构形式
1）威格士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。
2）威格士柱塞和柱塞套是一对精密偶件，经配对研磨后不能互换，要求有高的精度和光洁度和好的耐磨性，其径向间隙为0.002～0.003mm
3）威格士柱塞头部圆柱面上切有斜槽，并通过径向孔、轴向孔与顶部相通，其目的是改变循环供油量；柱塞套上制有进、回油孔，均与泵上体内低压油腔相通，柱塞套装入泵上体后，应用定位螺钉定位。
VICKERS威格士柱塞头部斜槽的位置不同，改变供油量的方法也不同。 威格士油泵回油过程
① 柱塞往复运动总行程L是不变的，由凸轮的升程决定。
② 柱塞每循环的供油量大小取决于供油行程,供油行程不受凸轮轴控制是可变的。
③ 供油开始时刻不随供油行程的变化而变化。
④ 转动柱塞可改变供油终了时刻，从而改变供油量 (现货总代理)的一级合作伙伴,专业经营美国VICKERS系列(Q)V10、V20 、20V、25V、35V、45V双联叶片泵：2520V、3520V、3525V、4520V、4525V、4535V变量柱塞泵：
