ステンレス鋼製オリフィスプレート内壁面の高速流動研磨 High Speed Flow Finishing of Inner Wall of Stainless Steel Orifice Plate 山本, 桂一郎 黒部, 利次 中森, 啓介 Copyright © The Japan Society for Precision Engineering 精密工学会 Stainless steel orifice plate installed into a gas flow controlled device is necessary to finish an inner wall of it. High speed slurry flow finishing method developed in our laboratory has been applied to polish the inner wall of orifice plate. Present paper focuses on the relationship between finishing characteristics and gas flow rate through the finished orifice plate. Experiments are conducted under the conditions of high flow rate of slurry suspending the aluminum oxide grains into city water. It is found that surface roughness of the inner wall of trumped-shape hole has decreased with the flow pass number. SEM micrographs indicate that the stripe-pattern on inner wall surface of as-received orifice plate have disappeared with the slurry flow pass number, but the dimension of hole has increased in size. Measurements of gas flow volume through the polished orifice plate show that finishing charac-teristics influences on gas flow curve. 精密工学会 = The Japan Society for Precision Engineering 2003-01-01 2017-10-03 jpn journal article VoR http://hdl.handle.net/2297/42795 https://kanazawa-u.repo.nii.ac.jp/records/9340 10.2493/jjspe.69.79 https://www.jstage.jst.go.jp/browse/jjspe/-char/ja/ http://www.jspe.or.jp/ AN1003250X 0912-0289 精密工学会誌 = Journal of the Japan Society for Precision Engineering 69 1 79 83 https://kanazawa-u.repo.nii.ac.jp/record/9340/files/TE-PR-KUROBE-T-79.pdf application/pdf 2.3 MB 2017-10-03
