The reliability of the numerical calculation method is verified by comparing the experimental data and numerical simulation results. The clearance is 0.1, 0.15, 0.2, 0.3 and 0.5 mm, respectively. The results show that the wear of the centrifugal pump blades is mainly concentrated in the end part and the inlet part of the blade, and the wear of the pressure surface at the end of the suction surface and the front of the blade is more serious. As the clearance increases, the maximum wear value in the impeller increases first and then decreases, reaching a maximum at 0.15 mm. With the increase of the clearance, the wear degree and the wear rate of the volute wall surface first increase and then decrease, and reach the maximum at 0.2 mm. With the increase of the clearance and the concentration of the fluid medium, the wear at the clearance of the centrifugal pump is more serious, and the severe wear area exhibits a point-like circumferential distribution.<\/jats:p>","DOI":"10.3390\/sym12122003","type":"journal-article","created":{"date-parts":[[2020,12,10]],"date-time":"2020-12-10T20:18:22Z","timestamp":1607631502000},"page":"2003","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Study on the Effects of the Wear-Rings Clearance on the Solid-Liquid Two-Phase Flow Characteristics of Centrifugal Pumps"],"prefix":"10.3390","volume":"12","author":[{"given":"Chaoshou","family":"Yan","sequence":"first","affiliation":[{"name":"College of Mechanical Engineering, Zhejiang University of Technology, Zhejiang 310023, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianfei","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Zhejiang University of Technology, Zhejiang 310023, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7112-2940","authenticated-orcid":false,"given":"Shuihua","family":"Zheng","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Zhejiang University of Technology, Zhejiang 310023, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bin","family":"Huang","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Zhejiang University of Technology, Zhejiang 310023, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiacheng","family":"Dai","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Zhejiang University of Technology, Zhejiang 310023, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,12,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"14","DOI":"10.1016\/j.powtec.2007.09.014","article-title":"Effects of using two- versus three-dimensional computational modeling of fluidized beds: Part II, budget analysis","volume":"182","author":"Xie","year":"2008","journal-title":"Powder Technol."},{"key":"ref_2","first-page":"719","article-title":"3D Numerical Simulation of Turbulent Flow and Wear Characteristics of Slurry Pump","volume":"20","author":"Wu","year":"2009","journal-title":"China Mech.
