1.故障现象我项目部1台CQ3253SMG324型自卸汽车,配装WP10.290E32型潍柴柴油机。该车运输过程中,驾驶员发现柴油机机油压力报警灯突然点亮,机油压力表显示机油压力为0.1MPa(正常机油压力为0.25~0.35MPa),明显低于规定值。机油压力过低会造成柴油机各润滑部位润滑不良、摩擦阻力增大、磨损加剧。还可造成柴油机过热,影响柴油机使用寿命,甚至造成恶性柴油机事故。2.原因分析维修人员对该柴油机结构分析后认为,机油压力低可能有5种原因:一是机油量过少、机油黏度过低,以及燃油
1. Symptom I project a CQ3253SMG324 dump truck, equipped with WP10.290E32 type Weichai diesel engine. The car transport process, the driver found diesel engine oil pressure alarm light suddenly lit, the oil pressure gauge shows the oil pressure of 0.1MPa (normal oil pressure of 0.25 ~ 0.35MPa), significantly lower than the specified value. Low oil pressure will result in poor lubrication of the lubricating parts of diesel engine, frictional resistance increases, wear increased. Diesel can also cause overheating, affecting the life of diesel engines, and even cause a vicious diesel accident. 2. Analysis of the reasons the maintenance personnel of the diesel engine structure analysis that the low oil pressure may have five reasons: First, the amount of oil is too small, the oil viscosity is too low, and fuel
