1不经磨合试运转就带负荷作业新购机或大修后的发动机,未经磨合试运转就带负荷作业,将会造成运动零件的严重磨损,进而使零件丧失工作能力,缩短整机使用寿命。为了减轻零件在初始阶段的磨损,检查并排除零件在制造、修理、装配中存在的问题,使整机各部件相互协调,新购机或大修后的发动机,应按相应的规范(负荷由小到大,转速由低到高,档位由低到高)进行磨合试运转,经检查调整后再加负荷投入作业。这样做可以充分发挥机械效能,延长使用寿命,防止事故发生。
1 Without running-in test run with a load of work After the new purchase or overhaul of the engine, running without trial run with the load operation, will cause serious wear and tear of moving parts, thereby enabling the loss of work ability of parts and shorten the life of the machine . In order to reduce the wear and tear of parts in the initial stage, check and exclude the parts in the manufacture, repair, assembly problems, so that all parts of the machine coordination, the new purchase or overhaul of the engine, according to the corresponding specification (load from small To large, speed from low to high, stalls from low to high) run trial run, the inspection and adjustment plus load into operation. Doing so can give full play to mechanical performance, extend the service life and prevent accidents.
