钻机动力驱动系统是决定钻机整体结构和性能的重要环节之一。随着工业技术的不断进步和一些高新机电产品的不断涌现,钻机动力驱动系统也随之发生了许多根本性的改变。那些传统的动力驱动方式(如柴油机驱动、交流异步电机驱动)正在逐步被一些更先进的动力驱动系统所取代(如直流无级调速、液压无级调速、交流变频无级调 Drilling rig power drive system is to determine the overall structure and performance of drilling an important part. With the continuous improvement of industrial technology and the constant emergence of some high-tech electromechanical products, many fundamental changes have taken place in the rig drive system. Those traditional power-driven methods (such as diesel-driven, AC induction motor drives) are gradually being replaced by some of the more advanced power-driven systems (such as DC stepless speed regulation, hydraulic stepless speed regulation, AC variable frequency stepless
