缸套是柴油机的主要零件之一,一旦出现故障就需整机拆检。缸套除早期磨损,还常常发生裂纹。缸套出现裂纹后,会给柴油机造成不良后果。若裂纹处漏水,冷却水会进入缸套内,活塞顶部积水过多时,就会发生“顶缸”事故,将连杆顶弯;冷却水进入曲轴箱,将使 Cylinder liner is one of the main components of diesel engine, once the failure requires the whole machine dismantling. In addition to early wear cylinder liner, but also often crack. After the cylinder liner cracks, diesel engines will have adverse consequences. If the crack leaks, the cooling water will enter the liner, the piston top too much water, there will be a “top cylinder” accident, the connecting rod bending; cooling water into the crankcase, will make
