柴油机油底壳内进水是种较严重的故障。其危害是:冷却系中水量减少,水套中的水温增高,高温零件的热量不能及时被带走,造成柴油机过热。机油与水混合呈乳化状,机油粘度下降,零件摩擦表面间油膜的表面张力减少,造成润滑条件恶化,增加了运动零件间的摩擦阻力和阻力矩并使磨损加剧。如对此故障不及时发现和排除,将会导致柴油机的损坏,为帮助用户更好地使用4125型柴油机,现就此故障产生的原因和检查方法分析如下: 一、空气滤清器的油盆内进水
Diesel engine oil sump is a more serious fault. The harm is: cooling system to reduce the amount of water, the water temperature in the water jacket increases, the high temperature parts of the heat can not be taken away in time, causing the diesel engine overheating. Oil mixed with water was emulsified, oil viscosity decreased, the friction surface between parts of the oil film surface tension decreased, resulting in deterioration of lubrication conditions, increased friction between the moving parts resistance and drag torque and wear increased. If this failure is not found and eliminated in time, will lead to diesel engine damage, in order to help users better use of 4125 diesel engine, now the cause of this failure and inspection methods are as follows: First, the air filter oil pan Water
