Abstract


Q25H52 electro-hydraulic circulation pump is a new type of high - speed centrifugal pumps , specialty power equipment is mainly used for the study of this topic Q25H52 electro-hydraulic circulation pump to draw the shape of the impeller , drawing optimization and performance test results of three parts : 1 . draw the shape of the impeller impeller is the main part of the centrifugal pump performance , draw the shape of the centrifugal pump impeller that draw out the impeller front and back cover of the blade -type line , painted - a direct relationship between the set of the performance of the products , the impeller design the most critical step . This paper presents a new face of the shaft axis plane projection rendering method . First impeller simple geometric analysis , determine the the impeller front cover by a straight line and two arcs constitute the rear cover is a straight line and an arc type line after a small amount of numerical calculation , each parameter the equation expressed , last use matlab computing programming , painted type impeller can be calculated by the computer by entering a set of parameters completed after modified only by changing the corresponding parameters can greatly simplify the calculation . The accuracy of the results is very high , close to the shape of the theoretical design . Points impeller line of \Optimize the design of the impeller design is complete , the need to optimize the design of the impeller , the impeller optimized design can improve the impeller shape significantly improved impeller efficiency impeller design must . The papers selected Orthogonal Optimization Method . The so-called orthogonal design, is the use of a method of the system prior to a special form - orthogonal table to scientific arrangements of the test , and test data analysis . In this paper, L1 6 (45) Finally, the table of drawing two rounds of optimization , close to the theoretical results optimized by the test results , it is optimized to good effect . Performance test is completed impeller design Q25H52 electro-hydraulic circulation pump performance testing , and inspection work in the case of different flow , speed , and ventilation , the test results show that the stable and efficient Q25H52 electro-hydraulic circulation pump work to meet the design requirements .
