摘要
随着电控系统的不断发展和钻井自动化要求的不断提高,交流变频绞车的优点体现得越来越明显,而交流变频单速绞车不能同时满足钩速和钩载要求;双速绞车虽然可以通过换挡获得理想的提升性能,但受机械换挡结构的制约,换挡劳动强度大,且必须停车才能换挡,效率低。应用一种新型的液压湿式离合器,通过合理的机械结构、液压系统及电控系统,实现了绞车的自动换挡。
VFD Dual-speed Drawworks is commonly used in drilling,the ideal performance curve can be obtained by changing the shifting,but it must be stopped before shifting,it is difficult to finish the gear changing.In view of this situation,a new type of hydraulic wet clutch in our drawworks is used,and its mechanical structure,hydraulic system and electronic control systems are designed to finish the process of Auto-gearing automatically.
