1 维修要求与检测目的工程机械维修是为了保持或恢复原有功能而采取的技术管理措施。现代维修理论强调维修要以可靠性为中心,维修的主要任务是通过控制各种影响因素,使机械的可靠性保持在一定水平上。机械维修分为修复性维修和预防性维修。修复性维修是指把失效的产品恢复到规定状态所进行的维修活动,也称为排除故障维修。进行此类维修时,故障已被发现,检测的主要作用是进一步找原因,以确定故障的具体部位,
1 Maintenance requirements and inspection purposes Maintenance of engineering machinery is a technical management measure taken to maintain or restore the original functions. Modern maintenance theory emphasizes that maintenance must be centered on reliability. The main task of maintenance is to maintain the reliability of machinery at a certain level by controlling various influencing factors. Mechanical maintenance is divided into repair and preventive maintenance. Restorative maintenance refers to maintenance activities that are performed to restore a failed product to a specified state. It is also referred to as troubleshooting. When such maintenance is performed, the fault has been discovered. The main role of the test is to find out the cause further to determine the specific location of the fault.
