一九八○年一月二十二日至二十五日,美国SKYTOP/BREWSTER公司T·考德尔和美国通用电器公司W·马哈非与中方技术座谈小组举行了技术座谈。座谈中,美方人员向我方介绍了二个公司合制的电动钻机的设计、配套、使用、维修等方面的特点及一些安全注意事项。由于电动钻机具有传动效率较高,性能安全可靠,调节幅度较广,调节控制方便,体积小、重量轻、噪音小、费用省,布置空阔,整洁美观、自动化程度较高,可以实现文明作业等一系列优点,因此电动钻机不仅从海洋发展到了陆地,而且从大型钻机发展
From January 22 to January 25, 1980, T · Cowrell, SKYTOP / Brewster Company of the United States, and W · Mahathir, General Electric Company of the United States held technical discussions with the Chinese technical panel. During the discussion, the personnel from the United States introduced to us the characteristics of the design, package, use, maintenance and other aspects of the electric drilling rig manufactured by the two companies and some safety precautions. Because electric drilling rig has the advantages of high transmission efficiency, safe and reliable performance, wide range of adjustment, convenient adjustment and control, small size, light weight, small noise, low cost, spacious layout, clean and beautiful appearance and high degree of automation, And a series of advantages, so electric drilling rig not only from the ocean to land, but also from the development of large rig
