一、前言目前,国内外的陆用石油钻机大部分都以柴油机作动力,在柴油机和传动(如液力偶合器、液力变矩器),尤其是液力变矩器的应用最为广泛。国产ZJ-130Ⅱ型、Ⅲ型钻机全部配备了液力变矩器,大大改善了柴油机的动力特性。但是,目前国内使用的各类石油钻机所配备的液力变矩器,多数性能不够理想,效率较低。如罗马尼亚生产的以及国内仿制 I. Introduction At present, most domestic and overseas land-based oil drilling rigs are powered by diesel engines. Diesel engines and transmissions (such as hydraulic couplings and torque converters), especially torque converters, are the most widely used. Domestic ZJ-130 Ⅱ type, Ⅲ drilling rig equipped with all the torque converter, greatly improving the dynamic characteristics of diesel engines. However, most of the hydraulic torque converters currently used in domestic oil rigs are not ideal and most inefficient. Such as those produced in Romania and domestic ones
