理论与实践已证明，机械设备拆卸检修后，可能导致可靠性降低或产生某些故障。作为勘探钻井设备，往往在地处偏远、各种条件较差的环境下进行生产作业，如何提高设备检修后的可靠性，避免给钻探作业生产带来不应有的损失，是一个应该给予高度重视的问题。涉及设备检修质量的因 Theory and practice have proved that mechanical equipment disassembly and maintenance may lead to reduced reliability or produce some failures. As a drilling equipment for exploration and drilling, production operations are often carried out in remote and poor conditions. How to improve the reliability after equipment maintenance and avoid undue losses to the drilling operations is an important issue that should be given to the height Pay attention to the problem.
