With this turbocharger on high altitude area , the power of diesel engine need not be modified or less modified , which meets the charging need of the diesel locomotive in the west plateau condition in china 特别是在高原地带,装用这种增压器后,能使柴油机功率少修正或不修正,较好地满足了铁路内燃机车在西部高原条件下的增压需要。
This new technology changes from the traditional method by which the induced and compressor wheel separately are designed and produced to a new one by which the one - piece compressor is designed . on the basis of this new technology and the optimum blade profile , the performance of both the compressor and the turbocharger is largely improved . through the heating power calculation of the compressor , the analysis of the surge and the block of the compressor , the test - bed performance test of the turbocharger , the matching test of turbocharger and diesel engine , the propulsion test of the turbocharger on plateau condition , it is proved that the newly - designed compressor not only has high efficiency , but also improves the flow distribution in the high efficiency area so that the propulsion line can run through the high efficiency area 主要内容包括:提出一种全新的压气机叶轮技术和概念,这种技术将传统的导风轮和压气机分开设计、单独加工改为整体设计、整体加工的单体叶轮;从增压器与柴油机配机计算所得出的基本参数出发,通过对压气机进行热力计算,确定压气机的基本结构参数;再对叶型以及叶轮轮廓与叶轮罩壳的配合间隙进行优化,对新设计的压气机进行喘振和堵塞分析;通过增压器平台性能试验,验证了新设计的压气机的性能水平得到了较大的提高,达到了提高增压器的整体性能水平的目的;通过增压器与柴油机配机试验、以及增压器用于高原条件下的牵引试验,验证了新设计的压气机不但具有高效率,还改善了高效率区的流量分布,使牵引特性线贯穿高效率区。
