Problems solved by technology

[0003] The traditional design method is based on the velocity coefficient method and improves the pump model with water as the medium according to experience. However, the factors considered in this design are too single, and only the hydraulic performance of the high-temperature pump is considered. A very important index, that is, cavitation performance and safety reliability, needs to ensure that the high temperature pump has passed the test of continuous productive operation for a long time

Abstract

The invention is a multi-variable and multi-objective parallel optimization method for high-temperature pump design. The invention is based on the multi-objective and multi-disciplinary optimization foundation. The process is modular, the first module is the experimental design module, the second module is the multi-objective parallel optimization module, and the third module is the optimal analysis and redesign module. The invention combines CFD calculation and finite element analysis, establishes a database of the high-temperature pump, evaluates three indexes of hydraulic performance, cavitation performance and safety and reliability, and obtains the most optimal three optimization indexes of the high-temperature pump with multiple design variables. The optimal design and the worst design are used, and the results of the worst design are used to constrain the optimal design, so as to establish a multi-variable and multi-objective parallel high-temperature pump design optimization method.

Description

technical field [0001] The invention relates to an optimization design method of a high temperature pump, in particular to a multivariable and multiobjective parallel optimization method for the design of a high temperature pump. Background technique [0002] High temperature pumps are widely used in power generation, petroleum, chemical, pharmaceutical and many other fields. With the improvement of national standards, the requirements for the performance and safety and reliability of high-temperature pumps are getting higher and higher, and more and more manufacturers require a leak-free process environment for the medium they transport, and it is urgent to choose an ideal pump. type. At present, the demand for high-end high-temperature pumps is increasing. However, it is difficult to achieve breakthroughs in the development of large-scale industrial pumps in China, and most of them rely on imports. The design of high-temperature and high-pressure centrifugal pumps involv...
