一、概况我队自1972年以来，全部使用油压钻机。为了解决辽宁式拧管机的配套问题，我们先后试验过发电机——电动机和软轴传动方案，因多种因素的限制，均未能理想地使用于生产，加上辽宁式技管机本身在设计上的缺点，如密封性差，泥砂易渗入造成齿轮的严重磨损；正反向离合片亦易因磨损和过载而损坏；加之缺少配件，所以，队上的辽宁式拧管机全部停用。 I. Overview Our team has used hydraulic rigs since 1972. In order to solve the supporting problems of the Liaoning-style screwing machine, we have tested the generator-motor and flexible shaft transmission solutions. Due to the limitations of various factors, they have not been ideally used in production, coupled with the Liaoning-style tube machine itself. Disadvantages in the design, such as poor sealing, easy to infiltrate the mud caused by the serious wear of the gear; positive and negative clutch plates are also easy to damage due to wear and overload; coupled with the lack of accessories, so the team on the Liaoning-style screw machine all disabled .
