Abstract


This topic is based on currently operates in the introduction of turbocharger VTC254 , based on the characteristics of China 's railway locomotive , to address the needs of the western highlands of the internal combustion engine supercharged and China need for speed railway locomotive on China's current main models 16V280 diesel engine - turbocharger matching , especially for the compressor . The main contents include : This paper presents a new compressor wheel technology and concepts , this technology will be separated from the the traditional wind guide wheel and compressor design, processing alone changed the overall design , the overall processing monomer impeller ; turbocharger diesel engine with the machine to calculate the results of basic parameters the compressor thermal calculation to determine the basic structural parameters of the compressor ; optimization of leaf type and impeller contour impeller casing with the gap on the new design of the compressor test through the turbocharger platform performance , the level of performance of the new compressor design has been greatly improved , to improve the overall level of performance of the turbocharger purpose ; turbocharger conducted surge and clogging ; diesel engine with machine test, and the turbocharger is used to plateau under the conditions of the traction test , to verify that the new design of the compressor having a high efficiency not only improve the flow distribution of the area of high efficiency , so that the traction characteristics line runs through the zone of high efficiency . From the the split impeller to the overall impeller , on the level of technology already has a good foundation , larger anteversion in the forward - backward curved impeller design through five-axis milling machine to achieve . New type impeller can effectively reduce the shunt loss , the undercurrent loss , friction loss , blast circulation loss , can effectively improve the efficiency of the compressor , the level of performance of the diesel engine , to improve the economic and operational metrics . Since the product successfully developed to the present, there are more than 300 units in operation . Especially in the highlands , equipped with turbocharger , make less diesel power correction or amendment , to better meet the supercharger needs of diesel locomotives in the western highlands conditions .
