新195柴油机从1965年试制已经使用十多年了,在实标使用中,存在下述问题. 一、部分零部件耐磨性能较差 1.曲轴新195柴油机采用球墨铸铁曲轴,由于某些厂采用含硫、磷量较高的生铁进行浇铸,从而带来球化率较差的缺陷,以及感应淬火曲轴表面的工艺不够稳定等因素,而引起曲轴不耐磨.同时,在使用中,由于机油不对牌号,用油不清洁、空气滤清器不起作用等也造成曲轴不耐磨. The new 195 diesel engine from 1965 trial production has been used for more than 10 years, in the actual use, there are the following problems: First, some parts wear poor performance 1. Crankshaft 195 diesel engine with ductile iron crankshaft, due to certain plant The use of sulfur, phosphorus, high-grade cast iron casting, resulting in poor balling rate of defects, and the induction hardening of the surface of the crankshaft is not stable enough process and other factors, resulting in the crankshaft wear-resistant at the same time, in use, due to Oil wrong grades, oil is not clean, the air filter does not work, also caused the crankshaft not wear.
