摘要
PCT数字式液压系统检测仪 ,根据极板在收放过程中仪器内部压力与时间的关系曲线 ,以及一个压力变化周期内 ,井径与时间的关系曲线 ,来检测仪器液压系统和井径臂的工作性能 ,为维修仪器提供一种可靠的检测手段。
The PCT digital monitor examines the function of the hydraulic system and caliber arm according to the tool′s internal pressure time curve during the pad′s opening and closing and the caliber time curve in the period of the variation of pressure. It offers a reliable means to maintaining tools.
