缸套穴蚀是指气缸套与水接触的外表面被水“腐蚀”成一个个的孔洞,其穴蚀的程度与柴油发动机工作负荷的加大、工作时间的延长成比例加深。缸套在其内表面受磨损、外表面受穴蚀的联合作用下提前被淘汰。关于缸套穴蚀的理论众说纷纭,但比较一致的看法是气泡与电化学复合的侵蚀理论。这种理论可解释为:当柴油发动机在工作时,缸套受上下往复运动的活塞的纵向侧偏力的连续作用,由于运动的速度极快,从而使缸套产生高频振动。活塞与缸套的间隙越大,活塞侧偏
Liner cavitation refers to the outer surface of the cylinder liner in contact with water is “eroded” by water into a hole, the extent of its cavitation and diesel engine workload increases, working hours extended in proportion to deepen. Cylinder liner in the inner surface of its wear and tear, the outer surface of the joint action by the erosion ahead of be eliminated. There are many different theories about the cavitation of cylinder liner, but the more common view is the erosion theory of bubble and electrochemical compound. This theory can be explained as the continuous action of the cylinder liner under the longitudinal side biases of the piston reciprocating up and down while the diesel engine is in operation, resulting in high-frequency vibration of the liner due to the extremely fast movement. Piston and cylinder liner of the larger the gap, the piston side
