气缸套在正常工作条件下,磨损是有一定规律的。一般是在活塞环运动区域内磨损较大,且不均匀。沿气缸套长度方向逐渐磨损成不规则的倒锥形,最大磨损部位是当活塞处在上止点位置时,第一道气环所对应的环形壁面。气缸套在活塞环运动区域之外磨损很少,特别是在磨损最大断面以上部位,几乎投有磨损,所以此处形成明显的台肩。造成这种不均匀磨损的主要原因有:(1)活塞处于上止点时,在压缩压力或爆发压力的作用下,第一道活塞环对缸壁的正压
Cylinder liner in normal working conditions, wear there is a certain law. Generally wear large piston ring movement area, and uneven. Along the length of the cylinder liner gradually worn irregular inverted taper, the maximum wear parts is when the piston at the top dead center position, the first ring corresponding to the annular wall. Cylinder liner in the piston ring outside the area of motion less wear and tear, especially in the wear section above the maximum section, almost cast wear, so here to form a clear shoulder. The main reasons for this uneven wear are as follows: (1) When the piston is at top dead center, the positive pressure on the cylinder wall of the first piston ring under the action of compression pressure or explosion pressure
