Design and Timing Control for Centrifugal Compressor Impeller Predecissional Remanufacturing
摘要
Abstract
Aimed at the present situations of remanufacturing components that often occured the issues of 'lag of remanufacturing'or 'remanufacturing in advance',a design method of predecisional remanufacturing and timing control for centrifugal compressor impellers was presented herein.By choosing vital component characteristic structures,combined with the theory of fatigue life and basic design method of impellers,the structure and performance of the service mapping model was estab-lished,the predecisional remanufacturing design of vital components was implemented.Through the optimization of structure parameters,changing the service performances and remanufacturing points of components,and matching with product performance degradation inflection points,the predeci-sional remanufacturing timing control was implemented.Taking the PCL8L type of centrifugal com-pressor impeller as an example,three structure characteristis of impellers(outlet angle,entrance an-gle and the trailing edge thickness)were selected,the quantitative relationship among the impeller structure characteristics and the service fatigue lifes was built.Then,through the simulation analysis and considering the current preventive maintenance requirements,the predecisional remanufacturing of timing control for centrifugal compressors.关键词
