高镍铸铁排气管加工工艺研究

Research on Machining Technology of High Nickel Cast Iron Exhaust Pipe

以竞标机项目作为重大课题研究项目,针对近年来开发的110系列10缸机、8缸机排气管一直存在台架试验漏烟、遇高温变形的问题,经过专家研讨,尝试从排气管材料和结构入手进行改进,以避免跑冒滴漏的问题重复发生。

The bidding machine project is a major project of our institute in recent two years,but the exhaust pipes of 110 series 10cylinder and 8 cylinder engines developed in recent years have always had the problems of smoke leakage in bench test and deformation in case of high temperature.After expert discussion,we try to improve the material and structure of the exhaust pipe to avoid the recurrence of the problem of running,emitting,dripping and leaking.
