烧瓦的前兆柴油机工作中转速突然降低,负荷加重,发动机冒黑烟,机油压力下降,曲轴箱内发出“唧唧”的干摩擦声,这是烧瓦的前兆。遇到这种情况应立即停机,否则会进一步加重轴瓦的磨损,轴瓦与轴颈很快就会黏结抱死,发动机熄火。黏缸的前兆黏缸一般在柴油机严重缺水的情况下发生,黏 Burning tile precursors Diesel engine speed suddenly reduced, the load increased, the engine black smoke, oil pressure drops, the crankcase issued a “chirp” dry friction sound, which is a precursor to burning tile. Encounter this situation should be immediately shut down, otherwise it will further increase the wear of bearings, bearings and journals will soon be bonded and locked, the engine flameout. Sticky cylinder precursors sticky cylinder in the case of serious water shortage in diesel engines, sticky
