美国VICKERS柱塞泵内设有由液氦或制冷机冷却到极低温度的冷板。它使气体凝结，并保持凝结物的蒸汽压力低于泵的极限压力，从而达到抽气作用。低温抽气的主要作用是低温冷凝、低温吸附和低温捕集。①低温冷凝：气体分子冷凝在冷板表面上或冷凝在已冷凝的气体层上，其平衡压力基本上等于冷凝物的蒸气压。抽空气时，冷板温度必须低于 25K；抽氢时，冷板温度更低。低温冷凝抽气冷凝层厚度可达10毫米左右。②低温吸附：气体分子以一个单分子层厚 （10-8厘米数量级）被吸附到涂在冷板上的吸附剂表面上。吸附的平衡压力比相同温度下的蒸气压力低得多。如在 20K时氢的蒸气压力等于大气压力，用 20K的活性炭吸氢时吸附平衡压力则低于10-8 帕。这样就可能在较高温度下通过低温吸附来进行抽气。③低温捕集：在抽气温度下不能冷凝的气体分子，被不断增长的可冷凝气体层埋葬和吸附。
美国VICKERS柱塞泵可以认为是变量机构的控制不佳造成，如异物进入变量机构，在控制活塞上划出阶痕、磨痕、伤痕等，造成控制活塞运动不稳定。由于放大器能量不足或零件损坏、含有弹簧的控制活塞的阻尼器效能差，都会造成控制活塞运动不稳定。流量不稳定又往往伴随着压力波动。这类故障一般要拆开液压泵，更换受损零部件，加大阻尼，提高弹簧刚度和控制压力等。
美国VICKERS柱塞泵的斜盘倾角为零时称为中位，此时泵的输出流量应为零。但有时会出现中位偏离调整机构中点的现象，在中点时仍有流量输出。其原因是控制器的位置偏离、松动或损伤，需要重新调零、紧固或更换。泵的角度维持力不够、倾斜角耳轴磨损也会产生这种现象。

VICKERS电磁阀使用：
VICKERS电磁阀出来的先导油控制主换向阀阀芯的移动，使工作泵的来油进入动臂油缸实现动臂上升。比例先导减压阀的输出压力越大，控制主换向阀阀芯的位移越大，主换向阀通过的流量越大，动臂上升的速度越快。当操作手柄拉至极限位置时，手柄中的限位电磁铁通电，手柄在极限位置被吸合。动臂以{zd0}的速度上升，当升至动臂上位限位开关所限定的位置时，操作手柄限位电磁铁断电，手柄自动恢复到中位，动臂就可保持在所限定的位置。在动臂上升的过程中，若需要动臂在某一位置停留，则需将操作手柄退回中位。
VICKERS电磁阀主要用在电气液压伺服系统中作为执行元件(见液压伺服系统)。在伺服系统中，液压执行机构同电气及气动执行机构相比，具有快速性好、单位重量输出功率大、传动平稳、抗干扰能力强等特点。另一方面，在伺服系统中传递信号和校正特性时多用电气元件。因此，现代高性能的伺服系统也都采用电液方式，伺服阀就是这种系统的必需元件。[1]
