挖掘机是露天移动式的大中型设备。象 W-100_2~1型和 W-50_2~1型这种单机传动的挖掘机,易磨损件多,如不能做好配件的准备工作,检修方法不正确,故障率就要增高,设备就不能保持正常状态。抚顺某厂十多年来在使用、维修多种挖掘机的实际工作中得到了不少教训。过去新的挖掘机投入生产,运转一、二年,随机易损件用完后,设备状态即逐渐恶化。加以附属机修设备较少,检修工人凭经验检修,有的易损件检修后变更原尺寸,既不能保持原设计性能,同类型设备的配件又不能互换,给下次的检修工作及配件
Excavators are open-air large and medium-sized equipment. For single-machine excavators such as W-100_2~1 and W-50_2~1, there are many parts that are easily worn. If the spare parts cannot be prepared, the repair method is incorrect, the failure rate must be increased, and the equipment cannot Stay normal. A certain factory in Fushun has learned many lessons in the actual work of using and maintaining multiple excavators for more than a decade. In the past, new excavators were put into production. After one or two years of operation, the state of equipment gradually deteriorated after the use of random wearing parts. Less auxiliary machine repair equipment, overhaul workers with experience overhaul, some wearing parts after repair change the original size, can not maintain the original design performance, the same type of equipment accessories and can not be interchangeable, to the next overhaul work and accessories
