交流变频电动机是国外20世纪90年代新发展起来的一种先进的电动钻机。90年代后期,我国的科技人员和有关单位将交流变频调速技术应用于石油钻采设备,尤其是电驱动钻机,成为当今最受青昧的钻机。交流变频电动机与机械钻机和直流钻机相比,它采用了交流变频调速技术,能够适应钻井工艺的要求,简化了钻机的机械结构,减轻了维护保养工作,提高了安全型、可靠性和移运性。交流变频绞车体积小、质量轻、故障少、维护方便;调速范围宽,可实现无级调速,对提高钻井实效、优化钻井工艺等十分有利。
AC variable frequency motor is a new type of advanced electric drilling rig developed abroad in the 1990s. In the late 1990s, China’s scientific and technical personnel and relevant units applied AC speed control technology to petroleum drilling equipment, especially electric driven drilling rigs, becoming the most popular drill today. Compared with mechanical drilling rig and DC drilling rig, AC variable frequency induction motor adopts AC variable frequency speed regulation technology, which can adapt to the requirements of drilling technology, simplifies the mechanical structure of drilling rig, lightens the maintenance work, improves the safety, reliability and relocation Transport AC variable frequency winch small size, light weight, less failure, easy maintenance; speed range, enabling stepless speed regulation, to improve drilling effectiveness, optimization of drilling technology is very beneficial.
