The main structural parameters of the IR100-80-100A type chemical centrifugal pump have been optimized by means of an orthogonal test approach. The centrifugal pump has been modeled using the CFturbo software, and 16 sets of orthogonal-test schemes have been defined on the basis of 4 parameters, namely, the blade number, blade outlet angle, impeller outlet diameter, and impeller outlet width. Such analysis has been used to determine the influence of each index parameter on the pump working efficiency and identify a set of optimal combinations of such parameters. The internal flow field in the centrifugal pump has been simulated by using the PumLinx software. These numerical results have shown that, compared with the prototype pump, the outlet pressure and shaft power of the optimized pump can be significantly reduced, and the pump working efficiency can be improved by 5.59%. In the present study, some arguments are also provided to demonstrate that, with respect to other optimization methods, the orthogonal test approach is more convenient, and requires less test times.
