Application of Methods of the Optimum Control Theory for Development of High Efficiency Centrifugal Pumps

摘要

In the current environment that is noted for the tough competition both in the domestic and external markets, success of pump system manufacturers can be assured by improvement of their products. Centrifugal pumps must meet a number of key requirements regulated by the industrial global standards (ISO); also, they must comply with their functional purpose. Lately, the list of qualities that a pump is expected to feature at the same time has been expanded considerably, too. Meanwhile, manufacturers are facing a number of challenges related to both upgrading series production pumps and development of new models that would meet as much as possible the market demands. The dramatic increase of computer capacities over the last decades has boosted considerably the development of methods of multidimensional optimization and adaptation of search algorithms based on advanced computers. Statistical data processing is much easier; computational capabilities have increased, and integrated libraries of mathematical functions have expanded. This article deals with the general problem statement of parametric synthesis of geometry of the wet end of centrifugal pumps. Taking improvement of the centrifugal pump impeller as an example, the paper considers the main solution methods of the multi-factor optimization problem based on the comprehensive application of approaches of the optimum control theory and the experiment planning theory.
