柴油机工作时,在负荷不变的情况下,出现排管冒烟,机油温度急剧上升到90℃以上,机油压力突然大幅度下降,发出刺耳的“唧唧”声,运转吃力至自行停车,停机后摇转曲轴时摇不动,这就是烧瓦抱轴现象。烧瓦的中要原因是由于润滑不良,轴和轴瓦之间不能形成良好的油膜,在高速干摩擦、温度极高的情况下,轴和轴瓦粘合,造成轴和轴瓦的损坏。如在证状初期立即停车检查,尚能不致损坏曲轴。发生烧瓦事故
Diesel engine at work, under the same load conditions, the exhaust pipe smoke, the oil temperature rose sharply above 90 ℃, a sudden substantial decline in oil pressure, issued a harsh “chirp” sound, running hard to stop, after stopping Rocking crankshaft can not shake, this is the phenomenon of burning tile hold axle. The reason for burning the tile is that due to poor lubrication, a good oil film can not be formed between the shaft and the bearing shell. Under high-speed dry friction and high temperature conditions, the shaft and the bearing pad are bonded, causing damage to the shaft and the bearing pad. If early in the certificate parking inspection, still can not damage the crankshaft. Burning accident occurred
