Considering the incomplete symmetry of the internal flow of the prefabricated pumping station, deposition characteristics of the prefabricated pumping station under single\/double pumps were also analyzed. Double pumps were symmetrically distributed in the integrated prefabricated pump station, and the movement trajectories of particles at the bottom of the pump pit under the closing inlet valve were measured through the use of a high-speed photography experiment. Results showed that with the increase of the flow rate, the deposition rate of the separated prefabricated pumping station decreased. With an increase of the particle diameter, the movement of particles was farther away from the vertical barrier weir. In the range of particle diameter of 6 to 10 mm, the deposition rate decreased with the increase of the particle diameter. With the increase of the liquid level, the deposition rate decreased, first, and then increased again. In the case of the single pump operation, the deposition rate of the right pump operation was smaller than that of the left pump operation. The variation of the deposition rate when the right pump operated was basically the same as that when the dual pumps operated. The movement path of particle N1 was longer. With the decrease of the flow rate and the increase of the particle diameter, the following feature of the particle decreased, and it was easier to impact the walls and edges, which caused long-term deposition. The research results could provide some suggestions for the design of anti-deposition performance of prefabricated pumping station.<\/jats:p>","DOI":"10.3390\/sym12050760","type":"journal-article","created":{"date-parts":[[2020,5,7]],"date-time":"2020-05-07T04:46:07Z","timestamp":1588826767000},"page":"760","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Research on the Deposition Characteristics of Integrated Prefabricated Pumping Station"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2892-2117","authenticated-orcid":false,"given":"Kai","family":"Wang","sequence":"first","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"}]},{"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"}]},{"given":"Houlin","family":"Liu","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"}]},{"given":"Zixu","family":"Zhang","sequence":"additional","affiliation":[{"name":"United Automotive Electronic Systems Co., Ltd., Shanghai 201206, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li","family":"Zou","sequence":"additional","affiliation":[{"name":"School of Naval Architecture &amp; Ocean Engineering, Dalian University of Technology, Dalian 116024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhaogang","family":"Lu","sequence":"additional","affiliation":[{"name":"The 719th Research Institute of China Shipbuilding Industry Corporation, Wuhan 430064, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,5,6]]},"reference":[{"key":"ref_1","first-page":"77","article-title":"Optimal design of effective capacity of integrated prefabricated pumping station","volume":"3","author":"Hu","year":"2016","journal-title":"Gen.
