我坑两台进口的900匹马力的柴油发电机,按出厂要求,喷油压力为250(公斤/厘米~2)左右。优选前,每发一度电,平均油耗0.251(公斤/度)。高压喷油管平均使用寿命不到一个月。在保证喷油雾化良好的情况下,用爬山法降低喷油压力。从原来的250～260(公斤/厘米~2)逐步降到190(公斤/厘米~2)。结果油管寿命比原来延长 I pit two imported 900 horsepower diesel generators, according to the factory requirements, injection pressure of 250 (kg / cm ~ 2) or so. Before optimization, each hair once the electricity, the average fuel consumption of 0.251 (kg / degree). The average high-pressure fuel injection tube life of less than one month. In the case of good spray atomization to ensure that the use of hill climbing method to reduce fuel injection pressure. From the original 250 ~ 260 (kg / cm ~ 2) gradually reduced to 190 (kg / cm ~ 2). Results tubing life than the original extension
