摘要
石油钻井指重表是实时监测钻井安全状况的重要仪器,高效而精确地检定指重表对于减小安全隐患,预防安全事故的发生具有重要意义。采用新型泵控伺服液压技术研制了一种300kN石油钻井指重表检定装置,用户通过触摸屏设置加载方式和加载力值,PLC通过伺服变量机构控制油泵的输出流量,从而控制油缸的压力输出,以高精度力传感器为控制参考标准,可实现力值的精确输出。该装置具备力值-压力两种测控模式,可对石油指重表进行高效准确的室内检测。
Weight indication gauge is an important tool for telling whether the condition of during oil drilling is safe or not. It can reduce hidden danger and prevent accidents by verifying weight indication gauges high efficiently and precisely. Based on pump-controlled servo hydraulic technology, a deviee used to verify 300 kN weight indication gauge is designed for oil well drilling. With it, users can chose load modes and enter load force parameters in touch screen. The flow of the pump is controlled by PLC with servomotor, and the pressure of hydro cylinder is controlled also. High precise load cell is used as control standard, therefore precise force is obtained. With force control and pressure control modes, this device can verify weight indication gauge efficiently indoors.
