我们使用的管道工程机械有75%是属于大修期在一万工作小时的耐用型机械,其中的45%是通用型工程机械,如推土机、装载机,汽车式起重机等,50%是管道专用机械、如吊管机、立式弯管机、水平穿孔机、四弧焊机、沼泽地推土机和长管拖车等,还有5%是工作装置尚未配套的机械,如只有标准反铲斗的单功能单斗挖掘机等。从七十年代到如今,每台机器运转不过2000小时,大都处于正常磨损和故障偶发性期。我们对20%的耐用型机械检查时,发现有207项(次)非正常磨损和故障,不
Seventy-five percent of the pipeline engineering machinery we use belongs to durable machinery with an overhaul period of 10,000 work hours, of which 45% are general-purpose construction machinery such as bulldozers, loaders, and automobile cranes, and 50% are dedicated pipeline machinery. Such as pipelayers, vertical pipe benders, horizontal piercing machines, four-arc welders, marshland bulldozers and long-tube trailers, etc., and 5% are machines that are not equipped with work equipment, such as only standard backhoe buckets. Features single bucket excavator and so on. From the 1970s to the present, each machine has operated for less than 2,000 hours, and most of them are in the normal wear and failure accidental period. When we examined 20% of the durable machinery, we found 207 (secondary) abnormal wear and failures.
