柴油机连杆螺栓在运行中断裂将会引起捣缸,打坏缸盖、缸套,使连杆变形弯曲,甚至还会造成捣破机体、折断曲轴等,应在使用维修中注意预防。1.出现飞车、咬缸或翻车后,一定要对连杆螺栓仔细检查,当发现螺栓变形、裂损后,应及时更换。2.多次烧瓦或一次烧瓦严重时,连杆螺栓材料受高温退火作用,金相组织发生变化,机械强度下降,承载能力下降,应予换新。3.当连杆螺栓松脱或被拉长时,在完全松脱、断裂之前,因连杆轴承松旷,会发出较大的敲击声和振动,此时应立即停车,以免发生更大事故。4.检查螺栓旋紧扭矩时,若发现同
Diesel connecting rod bolts in the operation of the fracture will lead to pounding cylinder, broken cylinder head, cylinder liner, connecting rod deformation and bending, and even smashed the body, broken crankshaft, etc., should be used in the maintenance of attention to prevention. 1 appear speed, bite cylinder or overturned, be sure to check the connecting rod bolts, bolt deformation, cracked, should be promptly replaced. 2. Repeatedly burned or a tile is severe, the connecting rod bolt material by high temperature annealing, the microstructure changes, mechanical strength decreased, carrying capacity decreased, should be replaced. 3. When the connecting rod bolt is loosened or stretched out, before the complete loosening and breaking, because the connecting rod bearing is loose, it will make a large percussive sound and vibration. At this moment, stop immediately to avoid bigger ACCIDENT. 4. Check the bolt tightening torque, if found the same
