摘要
双通道气水龙头是空气反循环钻进工艺配套机具中的重要部分,其工作稳定性和部件寿命直接影响钻进过程的连续性。本文介绍为XY-44型立轴钻机配套设计的SLD89型双通道气水龙头的结构,并进行强度校核。通过生产性试验的检验,及时解决出现的各种问题,实践证明,该结构双通道气水龙头能够满足该项工艺的需要,应用效果良好。
Double-channel air-water swivel is important component of drilling tools which is used in air drilling technology of reverse circulation, its working stability and assembly life directly effect the continuous of drilling. This article introduce the Structure of SLD89 style double-channel air-water swivel which is designed for XY-44 style spindle drill and strength checking. Though productive testing, settle the problem in time, experience approve that this structure of swivel can satisfy requirement of reverse circulation technology, effect of application is well.
