摘要
针对水电厂中大规格不锈钢螺栓与螺母容易发生锁死或咬死的问题,设计、制造一套专用的检测装置,用于检测螺栓和螺母实际装配时螺栓伸长值,以判断咬合情况,筛查淘汰咬合螺栓。笔者介绍了该检测装置的技术要求、结构、使用方法和应用效果,分析应用过程中出现的问题并提出改进措施。该装置具有很好的推广价值,对涉及应用大型螺栓的行业和企业有一定的借鉴作用。
Aiming at the problem that large-sized stainless steel bolts and nuts in hydropower plants are prone to lock or bite,a special detection device is designed and manufactured to detect the bolt elongation value during the actual assembly of bolts and nuts,so as to judge the galling situation and screen out the galling bolts.The technical requirements,structure,use method and application effect of the detection device are introduced.The problems in the application process are analyzed and the improvement measures are put forward.The device has a good promotion value and has a certain reference for industries and enterprises involved in the application of large bolts.
