The working principle is similar to that of the ordinary hydraulic cylinder, with a manual jack, Jack is also the simplest oil cylinder.
工作原理与普通的液压油缸基本相似，拿一个手动千斤顶来说，千斤顶其实也就是个最简单的油缸了。
This paper expounds the design of processing techniques before hole-boring on the cylinder of upright post and hoisting jack used in the hydraulic support.
阐述了液压支架所用立柱、千斤顶的缸筒在上深孔钻镗床进行镗孔、滚压之前必须进行的加工工艺的设计。
Hydraulic jack: Uses the plunger or the hydraulic cylinder goes against as the rigidity lifts a hoisting jack.
油压千斤顶：采用柱塞或液压缸作为刚性顶举件的千斤顶。
The driller now operates the EZY-torque. The hydraulic cylinder slides out (up) causing the jack line to be pulled by the rig tong. The torque meter will indicate the torque line pull force.
此时司钻操作液压锚头，伸出液压缸拉紧大钳，扭矩表显示液压锚头绳的拉力。
The Driller now operates the EZY-Torque. The hydraulic cylinder slides out (up), causing the jack line to be pulled by the rig tong. The torque meter will indicate the torque line pull force.
司钻操作液压猫头，液压缸伸出，拉紧猫头绳，扭距仪将显示出当前的拉力。
