柴油机湿式缸套的故障,不仅造成机械不能正常运转,还给工作人员带来诸多疑难。从实践中得知,缸套的故障,均系使用和维修不当造成的。当前,国内外柴油机在设计、制造、材质和工艺等方面都有很大提高。在正常使用和维修的状况下,其工作寿命均应有8000h以上。然而,达到此指标的却是少数,究其原因有以下三个方面: 一、空气滤清系统失效 空气滤清系统失效,将形成缸套的磨料磨损,会使缸套使用寿命大幅度降低,此道理很久以前已作阐述,但至今仍未得控制。近期,有关部门来我处咨询:“新的进口机械为什么使用不足一年即出现烧机油”。“柴油机经大修后使用不足200h即出现烧机油,虽经多次修理(用原机进口配件)情况仍未有改变”等。可明确指出,此类问题
Diesel engine failure of the wet liner, not only caused the machine can not be normal operation, but also to the staff to bring many problems. From practice, cylinder liner failures are caused by the use and maintenance of improper. At present, the domestic and foreign diesel engines have been greatly improved in terms of design, manufacture, materials and workmanship. In normal use and maintenance of the situation, its working life should be more than 8000h. However, to reach this indicator is a minority, the reason for the following three aspects: First, the air filtration system failure Air filtration system failure, the formation of abrasive liner wear, will greatly reduce the service life of cylinder liner, This truth has been elaborated long ago, but it is still beyond our control. Recently, the relevant departments to my office advice: “Why the use of less than a year, the new imported machinery burning oil.” “Diesel overhaul after using less than 200h burning oil appears, despite repeated repair (with the original machine imported parts) the situation has not changed” and so on. Can clearly point out that such issues
