| 摘 要： | 研制的JC-15D绞车主要由绞车架、滚筒轴、320 kW电动机、液压盘式刹车、电气控制系统和润滑系统等组成。该绞车采用主电动机直接驱动滚筒轴,整个变速过程完全由主电动机交流变频控制系统操作实现,具有提升和下放钻具、取心和处理事故等功能;主电机还可实现恒钻速或恒钻压自动送钻,主刹车采用主电动机能耗制动,辅助刹车采用液压盘式刹车。试验情况表明,在井架上段的起升和下放及正常钻井过程中绞车运行平稳,润滑充分,密封及连接可靠;主电动机连续调速、能耗制动减速及零速悬停功能良好,主电动机恒钻压(恒钻速)自动送钻速度和扭矩能满足钻井工艺要求;滚筒缠绳整齐有序;液压辅助刹车灵敏可靠。截止到2011年7月5日,JC-15D绞车已无故障累计运行700 h。

| Abstract: | The JC-15D drawworks developed mainly consists of jack frame,drum shaft,320 kW motor,hydraulic disc brake,electric control system and lubrication system.The motor transmits power to the drum shaft through the coupling in a synchronous way.The overall variable speed process of the drawworks is completely achieved by the AC variable frequency control system.The advanced low-speed high-torque permanent magnet motor is adopted to drive the drum shaft directly.As a result,the drawworks structure is simplified remarkably and its mass is reduced,the transmission efficiency is improved,and the precise control of super-low speed continuously variable transmission is achieved.The field application has reached desirable effects. |
