lack of lube oil (quick starts&hot shutdowns) ? oil contamination ? ingestion of foreign objects ? restricted oil drainage ? low oil level ? operation on excessive side slopes ? abnormally high exhaust temperatures lack of lube oil oil not only lubricates the turbocharger’s spinning shaft and bearings, it also carries away heat. when oil flow s***/is reduced, heat is immediately transferred from the hot turbine wheel to the bearings, which are also heating up because of the increased friction due to the lack of oil. this combination causes the turbocharger shaft temperature to increase rapidly. if oil flow does not increase&the process continues, bearings will fail. once the bearings fail (which can happen in just seconds) seals, shaft, turbine and compres*** wheels can also be damaged. the principle causes of turbocharger bearing lubrication problems are low oil pressure, a bent, plugged/undersized oil lube supply line, plugged or restricted oil galleries in the turbocharger,/improper machine start-up&shutdown procedure. oil levels&pressure should always be closely monitored&all worn hoses&lines should be replaced. the turbocharger oil supply line should be checked frequently to make sure it is not kinked or bent&it should always be replaced with a line of equal size, length&strength. the easiest way to damage a turbocharger is through improper start-up&shutdown procedures. always idle the engine for at least 30 seconds (no load) after start-up&before shutdown. warming the engine up before applying a load allows oil pressure to build up and lines to fill with oil. idling the engine before shutdown allows the engine and turbocharger to cool. “hot” shutdowns can cause the turbocharger to fail because after high-speed operation the turbocharger will continue to rotate long after the engine has been shut off&oil pressure has dropped to zero. this will cause heat to build up and possibly damage bearings. it can also cause carbon and varnish deposits to form. oil contamination a second cause of turbocharger failures is contaminated oil. it can be caused by a worn or damaged oil filter/not changing the lube oil at recommended intervals. expecting the oil filter to remove dirt, sand, metal chips, etc. from the oil before they reach the engine/turbocharger can be a costly mistake because contaminated oil may completely bypass the engine oil filter if the oil filter/oil cooler is clogged, if the filter element is improperly installed, or if the oil is thick during cold weather. four good ways of avoiding oil contamination are: ? always inspect the engine thoroughly during major overhaul. 宜春约翰迪尔强鹿3029柴油机电热塞供应商,重庆美国JohnDeere发电机皮带R135193供应商,郑州johndeere约翰迪尔强鹿柴油机热交换器市场报价,日喀则强鹿柴油滤芯P550135代理商,百色JohnDeere主轴瓦RE529319多少钱,扬州约翰迪尔柴油发电机配件RE507852批发,西安强鹿柴油机进油管代理商,吐鲁番JohnDeere温器座RE64354供货商,湖北强鹿RE522372柴油滤芯价格行情,宿州强鹿johndeere约翰迪尔涡轮增压器供应商,巴音郭楞强鹿6090柴油发动机皮带张紧轮的价格,连云港强鹿柴油机AT21134止推轴承代理,周口约翰迪尔发动机汽缸盖缸体哪家好,玉树强鹿柴油发动机节恒温器市场报价,通化约翰迪尔C120联合收割机发动机配件批发,莱芜约翰迪尔水泵总成RE500734厂家供货,长沙强鹿R115250皮带轮批发商,天水强鹿柴油发电机组仪表盘厂家批发,湖州约翰迪尔主轴瓦RE65165价格,晋中johndeere主轴瓦公司,武汉强鹿T20073凸轮随动件代理,广州约翰.迪尔空气滤清器RE16809一级代理,甘孜右平衡轴TRE500448约翰迪尔柴油机市场报价,澳门离岛强鹿柴油机水泵哪家买,株洲强鹿加大止推轴承瓦RE534183厂家供货,淮北强鹿发电机配件6068TF258找哪家,邵阳强鹿6081柴油机机油泵哪家好,济南约翰迪尔E240LC挖掘机发动机配件哪家买,乌海JohnDeere传感器RE522794厂家供货,甘南JohnDeere挺铜柱RE540586信息,巴彦淖尔强鹿约翰迪尔3029气缸盖螺丝批发,咸阳约翰迪尔发动机气门挺杆厂家供应,齐齐哈尔JohnDeere水温传感器el52222公司,湖北约翰迪尔3029柴油机排气门厂家批发,淄博约翰迪尔R58979哪家好,南阳强鹿机滤RE57394公司,惠州约翰迪尔装载机发动机曲轴批发商,博尔塔拉美国强鹿JOHNDEERE柴油发电机配件厂家供应,上海约翰迪尔6068柴油机排气门批发价,信阳约翰迪尔6068柴油机气门油封的价格,兴安约翰迪尔强鹿喷油器垫圈价格行情,新疆约翰迪尔活塞RE529264一级代理,淄博约翰迪尔R58979厂家供应,鄂州强鹿柴油机喷油器代理商,安康强鹿4045柴油机曲轴哪家好,新疆约翰迪尔6081柴油机活塞环的价格,新界强鹿柴油发动机启动机供货商,阜新美国JohnDeere起动机RE70960哪里买,广安强鹿柴油机4045主轴瓦公司,潮州强鹿柴油机原装机油滤清器RE504836批发商,聊城约翰迪尔缸套水封圈AR98850找哪家,资阳强鹿柴油机气门挺杆的价格,丽江强鹿柴油发动机3029修理包哪家买,东莞约翰迪尔6J-1654拖拉机发动机配件供应商,怒江强鹿6090柴油发动机曲轴信息,宿州johndeere约翰迪尔强鹿柴油机油底壳信息,克孜勒苏强鹿6090柴油机主轴瓦信息,巴音郭楞约翰迪尔强鹿3029柴油机气门弹簧座找哪家,南充强鹿6081柴油机气门座圈代理商,乐山约翰迪尔发动机机油泵多少钱,七台河约翰迪尔强鹿气门室盖垫片R524468价格,博尔塔拉美国强鹿JOHNDEERE柴油发电机配件代理商,六盘水约翰迪尔6081柴油机温度传感器一级代理,恩施johndeere约翰迪尔强鹿柴油机喷油器批发价,台湾强鹿6068柴油机喷油器公司,look especially for any sludge/debris left in lube oil galleries. ?
