钻机、泥浆泵组合传动自一九六九年在我们局四○二队试验成功以来，已有九年多的时间了。钻机、泥浆泵组合传动（下简称组合传动钻机）是从改革XB-500型钻机开始的，通过不断地总结完善，逐步发展到ЗИФ-650型、XH-60型和XU-600型组合传动钻机。实践证明，组合传动钻机适应性比较强，它既适应直孔钻进，又适应斜孔钻进；既能适应大口径钢粒、合金钻进，又能适应小口径金刚石钻进。它具有节省设备、油料、搬迁费用，简化机场结构，便于安装拆卸等优点，深受群众欢迎，一九七八年以后已在全局推广使用。
It has been more than nine years since the test rigs for drilling rigs and mud pump units were successfully tested in our bureau in 1969. Drilling rig, mud pump combination transmission (hereinafter referred to as the combination of transmission drilling rig) is from the reform of the XB-500 drilling rig, through continuous improvement, and gradually developed to ЗИФ-650, XH-60 and XU-600-type combination drive rig . Practice has proved that the combination drive rig adaptability, it not only adapt to straight hole drilling, but also to adapt to inclined hole drilling; both to adapt to large-diameter steel, alloy drilling, but also to adapt to small-diameter diamond drilling. It has the advantages of saving equipment, oil, relocation expenses, simplifying airport structure, facilitating installation and disassembly, etc., which are well received by the public and have been promoted globally since 1978.
