内燃机车柴油机的发展要求高性能的增压器。为了提高45GP802型增压器的总效率,提高增压器配机喘振余量,以防冬季发生喘振及解决对粘污敏感性,减少运行中经常拆洗等问题,铁道部科学研究院机辆所协同天津机车车辆机械工厂在利用原有壳体和原有涡轮叶片的条件下,进行对45GP802型增压器的下述改进工作,并取得了明显的改进效果。
The development of diesel locomotive diesel engines require high performance superchargers. In order to improve the total efficiency of 45GP802 turbocharger and increase the surge margin of turbocharger, in order to prevent the occurrence of surge in winter and to solve the sensitivity to sticky dirt and reduce the frequent dismantling and washing during operation, Vehicles cooperated with Tianjin Locomotive and Rolling Stock Machinery Factory to make the following improvement work on 45GP802 turbocharger under the condition of using the original shell and original turbine blades and achieved obvious improvement effects.
