“…In the actual optimized design process, blade exit angle often varies from 15° to 40° and blade wrap angle often varies from 90° to 130° [16]. Some scholars studied the effects of blade exit angle and blade wrap angle on the hydraulic performances of the centrifugal pump [17][18][19]. The selection of blade wrap angle and blade exit angle mainly depend on the specific speed of the centrifugal pump and the actual optimized design experience.…”

“…A centrifugal pump was suggested, having a better efficiency and cavitation performance than the original one. In Zhou et al's study [32], a pump was designed using 16 impellers and 5 main impeller geometric parameters; the pump efficiency and head of the optimal pump had a significant improvement compared with the original pump. Wang et al [33] established a function relationship between three factors of impeller and the efficiency through the quadratic regression orthogonal test.…”

A multiobjective optimization technique based on the computational uid dynamics (CFD) simulations and the orthogonal test is proposed to reduce the pressure pulsation in this paper. ree levels of four well-known performance factors L 9 (3 4 ) were considered in the orthogonal test scheme: the number of blades, the blade setting angle, the hub ratio, and the distance between the blade and the guide vane. e evaluation indexes corresponded to the head, e ciency, shaft power, and pressure pulsation, respectively. An optimal con guration A 2 B 1 C 2 D 3 was obtained by comprehensive frequency analysis method, after intuitive and range analysis. In comparison with the nonoptimized model, the new design's head and e ciency increased by 17.8% and 4.26%, whilst the shaft power and the pressure pulsation coe cient reduced by 1.22% and 11%, respectively. Experiments conducted on the optimized pump were consistent with the CFD model. Six di erent rotational speed conditions in the optimal operating points were numerically calculated in order to explore the internal hydraulic characteristics of the optimized axial ow pump. It is veri ed that the comprehensive frequency analysis method based on the orthogonal test approach is e ective for the multiobjective optimization of the axial ow pump.

“…In order to improve the experimental efficiency, the staggered angles between impellers were arranged by orthogonal method. 15 In the test, two staggered angles were considered, one is 0°with experimental serial number 1, and the other is 22.5°(u/2) with experimental serial number 2. The experimental factors were named A, B, C, D, and E, for five-stage impellers, respectively.…”

In this article, the effects of clocking effect on performance and vibration intensity of a five-stage centrifugal pump were investigated by experimental tests. The vibration characteristics of five positions in the pump were measured, including axial direction of the pump and horizontal and vertical directions of pump inlet and outlet. There are eight clocking schemes between the impellers in the test, which are arranged by orthogonal experimental design. The test results show that the clocking effect of impellers has little effect on the head and efficiency of the five-stage pump in the whole flow rate. Compared with the results of 0°stagger angle clocking scheme between each impeller, in the whole flow rate, the pulsation of pump head and efficiency is just 1.5% and 1.3%, respectively, under other clocking schemes of impellers. Instead, the impeller clocking has a significant effect on the vibration characteristics of the model pump. The maximum vibration intensity of the five-stage pump locates in the vertical direction of pump inlet within the whole flow rate. Under the best clocking scheme of impellers, the maximum vibration intensity of the pump can decrease by 23.1% and the mean vibration intensity can decrease by 17.3%.
