随着柴油机强化性能的提高及气缸套壁厚的减小,加之使用、维护不当,气缸套外壁穴蚀穿孔及内表面异常磨损现象较普遍,特别是穴蚀,已成为气缸套早期损坏的主要原因。 1 气缸套外壁穴蚀的特点及原因气缸套穴蚀一般发生在承受主、次推力面一侧的气缸套中下部、水套狭窄的高温死角处、进水口、水流转弯处以及气缸套密封圈上缘。穴蚀较重区域 With the enhanced performance of diesel engines and cylinder liner wall thickness reduction, combined with the use, improper maintenance, cylinder liner outer wall perforation and abnormal wear on the inner surface of the phenomenon is more common, especially cavitation, has become the main cylinder liner damage the early the reason. 1 Cylinder liner wall pitting characteristics and causes Cylinder liner cavitation generally occurs in the host to withstand the thrust side of the cylinder liner in the lower part of the water jacket narrow high temperature dead corner, water inlet, water turns and cylinder liner seals On the edge. Cavitation heavier areas
