1.油底壳进水的排查方法(1)漏水特征Z12V190B型柴油机油底壳进水后,会有以下4个特征:一是柴油机连续工作数小时后,油底壳内的油位明显上升,即机油量增加,有时甚至是大幅度地增加。二是打开曲轴箱呼吸器后,有排冒白雾现象,有时呼吸器出口处还会有水珠产生。三是柴油机没有启动时检查机油质量,会发现油底壳内机油中含有水珠,启动数小时后检查机油会变成灰白色,有时还伴有气泡产生。四是观察仪表盘时会发现,机油压力表的读数较正常值低约90~200kPa。
1. Oil pan into the water inspection method (1) leakage characteristics Z12V190B diesel engine oil pan into the water, there will be the following four characteristics: First, the diesel engine working continuously hours, the oil level within the oil pan increased significantly , That is, the amount of oil increases, sometimes even dramatically increased. The second is to open the crankcase respirator, there are rows of white fog phenomenon, and sometimes there will be a droplet outlet respirator. Third, check the quality of the engine oil does not start, you will find that the oil pan contains water droplets, check the engine oil will turn gray hours after the start, and sometimes accompanied by bubbles. Four is observed dashboard will find that the readings of the oil pressure gauge lower than the normal value of about 90 ~ 200kPa.
