在全球的油气田压裂作业现场，传统压裂设备所采用动力传动系统的配置方式都是柴油发动机连接变速箱经传动轴驱动压裂柱塞泵工作，也就是说，动力源是柴油发动机，传动装置是变速箱和传动轴，执行元件是压裂柱塞泵。该配置模式存在以下缺点：(1)、体积大重量大：柴油机驱动变速箱经传动轴驱动压裂柱塞泵，体积大，重量大，运输受限，功率密度小。(2)、不环保：柴油发动机驱动的压裂设备在井场运行过程中，会产生发动机废气污染和噪音污染，噪音超过105dBA，严重影响周围居民的正常生活。(3)、不经济：柴油发动机驱动的压裂设备，设备初期的采购成本比较高，设备运行时单位功率燃料消耗费用高，发动机和变速箱的日常维护保养费用也很高。鉴于全球的油气开发设备正朝着“低能耗、低噪音、低排放”的方向发展，所以，传统以柴油发动机为动力源的压裂设备的上述缺点从一定程度上阻碍了非常规油气能源的开发进程。
