The result shows that the efficiency of the pump is maximal when the blade inlet angle is 12\u00b0. The pressure variation in the model with the inlet angle of 12\u00b0 was small and the amplitude of fluctuation was also not large. When the outlet angle was 90\u00b0, the pressure distribution in the outlet of the blades that are symmetrically distributed along the center of the diffuser shell was significantly better than that with other outlet angles. The effect of the blade wrap angle of the channel-diffuser on the energy performance of the pump was relatively small. The internal flow in the diffuser with the diffusion inlet shapes was steady for both the convex surface and concave surface. The diffusion inlet of the channel-diffuser blade corresponded to the outlet region of the impeller blade, which reflected a good matching. The fluctuation amplitude and the distribution range of the models with a uniform transition were smaller than those with non-uniform transition. In order to verify the effectiveness of the research results, an experimental test was carried out on the pump. The results show that when the flow rate is 850 m3\/h, the head of the pump is 138.67 m and the efficiency of pump is 69.48%.<\/jats:p>","DOI":"10.3390\/sym13020277","type":"journal-article","created":{"date-parts":[[2021,2,7]],"date-time":"2021-02-07T14:04:13Z","timestamp":1612706653000},"page":"277","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Influence of Channel-Diffuser Blades on Energy Performance of a Three-Stage Centrifugal Pump"],"prefix":"10.3390","volume":"13","author":[{"given":"Wenbin","family":"Zhao","sequence":"first","affiliation":[{"name":"School of Energy and Power Engineering, Jiangsu University, Zhenjiang 212013, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianbin","family":"Hu","sequence":"additional","affiliation":[{"name":"National Research Center of Pumps and Pumping System Engineering and Technology, Jiangsu University, Zhenjiang 212013, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2892-2117","authenticated-orcid":false,"given":"Kai","family":"Wang","sequence":"additional","affiliation":[{"name":"National Research Center of Pumps and Pumping System Engineering and Technology, Jiangsu University, Zhenjiang 212013, China"},{"name":"Institute of Fluid Engineering Equipment, Jiangsu Industrial Technology Research Institute (JITRI), Zhenjiang 212009, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1177\/1687814016644376","article-title":"Experimental Test on Impeller Clocking Effect in a Multistage Centrifugal Pump","volume":"8","author":"Tan","year":"2016","journal-title":"Adv.
