内燃机车运用废气涡轮增压系统,可以利用燃烧后的废气能量,有效的增加柴油机的功率输出,提高柴油机的工作效率,同时,在运用过程中,增压系统会出现一系列故障,比如,增压器喘振就是内燃机车运用中较为常见的故障,文章分析了东风4D型内燃机车在运用中增压器喘振的原因,并相应提出了预防与处理方法。
The use of exhaust turbocharging system for diesel locomotives can make use of the energy of the exhaust gas after combustion, effectively increase the power output of the diesel engine, and improve the working efficiency of the diesel engine. Meanwhile, during the operation, the turbocharger system has a series of faults, for example, The surge of compressor is the more common failure in the use of diesel locomotives. The article analyzes the reason of turbocharger surge during the operation of DF4D diesel locomotive and puts forward the methods of prevention and treatment accordingly.
