废气涡轮增压器是增压柴油机的关键部件,工作时涡轮以高达6万～10万r/min的转速运转,空气流量为0.17～0.68kg/s,压力可增加0.180～0.315MPa,能有效地提高发动机的工作效率。 1.常见故障 （1）漏油 增压器漏油常见为气端漏油,主要原因是,气端密封环工作不良、密封套间隙过大、密封圈损坏等,产生的根源有的是制造质量问题,有的是润滑不良造成磨损所致。其症状主要表现为烧机油;排气冒蓝烟;打开进气管路会发现管壁上沾有机油。此时,须更换密封环和密封套。
Exhaust gas turbocharger is a key component of turbocharged diesel engine, the work of the turbine to run up to 60,000 to 100,000 r / min speed, air flow of 0.17 ~ 0.68kg / s, the pressure can increase 0.180 ~ 0.315MPa, can be effective To improve the efficiency of the engine. 1. Common Faults (1) Oil leakage booster oil leakage is common for the gas side, mainly due to poor working gas seal ring, seal gap is too large, the ring damage, some of the root causes of manufacturing quality problems , Some are caused by poor lubrication caused by wear and tear. The main symptoms of burning oil; exhaust blue smoke; open the intake pipe will find the pipe wall stained with organic oil. In this case, replace the seal ring and gland.
