1.气缸套穴蚀的一般情况我段在检修东风型机车的过程中,发现10E207J型柴油机气缸套有穴蚀现象。穴蚀面积为16～60mm~2,深度为1.5～6mm,形状有针眼状、锅底状和蜂窝状的。发生的部位多数是在喷油器孔座和示功阀孔座安装密封的平面上。 10E207J型柴油机气缸套穴蚀后能导致气缸套穿孔,使气缸内燃气与冷却水路相通,破坏冷却造成虚水位。穴蚀缸套常因无法修复而报废。近年来我们利用粘接技术对穴蚀气缸套进行了修复。 2.穴蚀缸套的修复近几年来,粘接技术发展很快,粘接材料
1. The general situation of cylinder liner cavitation I paragraph overhaul Dongfeng locomotive in the process and found 10E207J diesel engine cylinder liner cavitation phenomenon. Cavitation area of 16 ~ 60mm ~ 2, depth of 1.5 ~ 6mm, the shape of a needle-like, pot bottom and honeycomb. The majority of the sites that occur are on the flat surface where the injector and pilot valve seats are mounted. 10E207J-type diesel engine cylinder liner cavitation can lead to perforation of the cylinder liner, so that the gas cylinder and cooling water passage connected to destroy the cooling caused by virtual water level. Cavitation liner often unable to repair and scrapped. In recent years, we use the adhesive technology to repair cavitation cylinder liner. 2. Cavitation liner repair In recent years, bonding technology has developed rapidly, bonding materials
