磨合对新使用的汽缸套,一定要按说明书要求进行磨合。因在制造和修理时,汽缸套虽然经过精细的机械加工,但放大观察,表面仍有微小的凹凸不平,摩擦面的实际接触面积比计算要求的小得多,各接触点所受的力比正常工作时大得多。同时,表面的凹凸不平部分还会互相嵌合,相互摩擦时会挤出润滑油,破坏油膜的形成,并发生撞击。新汽缸套如果不经磨合立即使用全负荷工作,摩擦表面就会产生拉伤、划痕或熔接等损坏,表面可能更加不平,磨损力度可
Running on the newly used cylinder liner, must be run in accordance with the instructions requirements. Because in the manufacture and repair, although the cylinder liner through the fine machining, but magnified observation, the surface is still slightly uneven, the actual contact area of the friction surface is much smaller than the calculation requirements, the contact point suffered by the force ratio Normally much larger. At the same time, the surface of the uneven part of each other will fit each other friction will squeeze the oil, the destruction of oil film formation, and the impact. If the new cylinder liner without the use of full load immediately work, the friction surface will produce strain, scratches or welding damage, the surface may be more uneven, wear strength can be
