我们单位一台阿特拉斯露天钻在发动机大修后,投产使用一个月时间(约200 h)、在施工现场打钻作业时,突然无法使用,既不能提起钻杆,又不能行走,使整个开挖工作陷于瘫痪,如果不及时处理,会影响整个工程进度。经检查发现,泵轴花键损坏。原因是,在安装发动机时,曲轴轴线与液压泵轴线不对中。当时,首先想到的是购买泵轴与连接盘总成,但无货;如果重新加工总成,从加工到热处理,约须10天时间,费用约2000多元。于是,采用了
One unit of Atlas open-air drill was put into operation for one month (about 200 hours) after overhauling the engine. When drilling at the construction site, it suddenly became unusable. It could neither lift the drill pipe nor walk, Excavation work is paralyzed, if not dealt with in time, will affect the progress of the entire project. After inspection found that the pump shaft spline damage. The reason is that the crankshaft axis is not aligned with the pump axis when installing the engine. At that time, the first thought was to purchase the pump shaft and connection plate assembly, but no goods; if the re-assembly, from processing to heat treatment, about 10 days time, cost about 2000 yuan. So, adopted
