1烧瓦转速突然自行降低,负荷加大,冒黑烟,机油压力下降,曲轴箱内发出“唧唧”干摩擦声,这是烧瓦的前兆。应立即停机检查曲轴和轴瓦,否则,在数秒钟后轴瓦与轴颈就有可能粘结抱死。2粘缸运转无力,水温表指示超过100℃,如果给机体上洒几滴水,会出现“嘶嘶”响声并冒水汽,水滴很快蒸发,这是粘缸的前兆。应停车怠速运转或摇转曲轴帮助冷却。千万不要立即停机熄火,否则,会使活塞与缸套发生粘缸。3气门落缸缸盖部位可听到“噹噹”敲击声(活
A burning tile speed suddenly reduced itself, the load increases, black smoke, oil pressure drops, the crankcase issued “Haw ” dry friction sound, which is a precursor to burning tile. Should immediately shut down to check the crankshaft and bearing, or, after a few seconds the bearing bush may be bonded and locking. 2 sticky cylinder running weakness, the water temperature gauge indicates more than 100 ℃, if the body to sprinkle a few drops of water, there will be “hiss ” sound and water vapor, water droplets quickly evaporated, which is sticky cylinder precursor. Stop idling or crank the crankshaft to help cool it. Do not immediately stop the flame, otherwise, will make the piston and cylinder liner sticky. 3 valve drop cylinder head parts can hear “Dangdang” percussion (live
