转盘独立电驱动方案及优越性

Advantages of independent and electrical drive rotary table

介绍了3种转盘独立电驱动方案,其优点是实现转盘单独无级变速,满足了钻井工艺的需要;容易实现转盘、转盘传动部分及其支撑结构的模块化设计;交流变频和电控技术的应用,提高了钻机的自动化水平;使钻机结构设计整体化;故障检修方便。指出了存在的问题。

Three independent and electrical drive manners normally applied for rotary table has shown following advantages, speed is adjusted steplessly, meeting with drilling process requirement,easy to integrate rotary table, transmission device and its spreader to be a module,with Variable Frequency Drive and relevant electrical control technology, the automation of drilling rig is up graded, easy to integrate the structural design of drilling rig, easy to deal with faults.
