以XY - 4型地质钻机为例 ,对常规异步电机驱动和交流变频调速驱动时的钻机能耗进行对比分析 ,结果表明 :后者能耗明显小于前者 ,证明钻机采用交流变频调速动力系统有显著的节能效果 ,为提高钻机性能、降低钻探成本提供了一个新的技术途径。 Taking XY - 4 geological drilling rig as an example, the energy consumption of conventional asynchronous motor driven and AC variable frequency drive is compared and analyzed. The results show that the energy consumption of the latter is obviously less than the former, which proves that the drilling rig adopts AC variable frequency speed control powertrain There is a significant energy saving effect, which provides a new technical way to improve drilling performance and reduce drilling costs.
