目前,在我国石油矿场上采用液力传动的钻机数量很大,而且还不断增加。从罗马尼亚进口的DH系列、F系列钻机;以及我国兰州石油化工机器厂生产的大型、中型钻机上均带有液力传动装置。尤其是液力变矩器的应用最为广泛。但是由于现场使用人员对于液力变矩器的性能、特点认识不足; At present, there are a large number of hydraulic transmission rigs used in China’s oil mines, and their numbers have also been on the rise. DH series imported from Romania, F series drilling rig; and China Lanzhou Petrochemical Machinery Factory production of large and medium-sized rig with hydraulic transmission. In particular, torque converter is the most widely used. However, due to the field use of torque converter performance, lack of understanding of the characteristics;
