6 S195柴油机使用和操作 6.1 新机磨合运转新购的柴油机或大修后的柴油机在投入正常使用前,务必进行磨合运转。因为这时柴油机相互配合作相对运动的零件表面,虽然都达到一定的表面粗糙度,但是从微观上看,表面仍然不很光滑,凹凸不平,甚至有明显的加工痕迹和毛刺。因此,新柴油机或大修后的柴油机必须经过磨合运转阶段,以便使相对运动的零件表面经过充分磨合而较为光滑,贴合更为充分,从而防止零件的表面损坏、早期磨损乃至发热咬死等,并因此而提高柴油机的使用寿命。柴油机试运转磨合阶段的基本原则是:时间为50
6 S195 Diesel Engine Operation and Operation 6.1 Running a new machine Running a newly purchased diesel engine or an overhauled diesel engine before starting normal operation must be carried out. Because at this time the relative cooperation of the diesel engine for the relative movement of the parts surface, although they have reached a certain degree of surface roughness, but from the microscopic point of view, the surface is still not smooth, uneven, and even obvious processing marks and burrs. Therefore, the new diesel engine or overhaul after the diesel engine must go through the running-in phase, in order to make the relative movement of the parts surface is fully run-in and smoother, fit more fully, so as to prevent parts surface damage, early wear and even heat died, And thus improve the life of diesel engine. The basic principle of running-in phase of diesel engine test is: the time is 50
