Title (EN) IMPELLER MANUFACTURING METHOD
(FR) PROCÉDÉ DE FABRICATION DE TURBINE
(JA) インペラ製造方法
Abstract:
(EN) The present invention reduces the time required for a smoothing step performed through polishing, etc., so as to improve the efficiency in manufacturing, from molding to smoothing of an impeller. The impeller manufacturing method according to the present invention comprises a molding step S1 for molding an impeller 10 by thermal fusion laminate molding; and a chemical polishing step S2 for polishing a wall 15 that defines a flow channel 14 included in the impeller 10 by bringing a polishing liquid 21 into contact with the wall. In the chemical polishing step S2, fluidity is imparted to the polishing liquid 21 within the flow channel 14. In the chemical polishing step S2, it is preferable for the polishing liquid 21 within the flow channel 14 to be imparted with fluidity by using a device equipped with: a polishing liquid tank 22 for storing the polishing liquid 21 and housing the impeller 10 therein; a channel 23 through which the polishing liquid 21 held in the polishing liquid tank 22 is supplied under pressure; and a supply part 24 which constitutes a terminal end of the channel 23, and which supplies the polishing liquid 21 to an inlet port 141 of each of a plurality of channels 14.
(FR) La présente invention réduit le temps requis pour effectuer une étape de lissage réalisée par polissage, etc., de façon à améliorer l'efficacité de fabrication d'une turbine, depuis le moulage jusqu'au lissage. Le procédé de fabrication de turbine selon la présente invention comprend une étape de moulage S1 pour mouler une turbine 10, par moulage stratifié par fusion thermique ; et une étape de polissage chimique S2 pour polir une paroi 15 qui définit un canal d'écoulement 14 situé dans la turbine 10, en amenant un liquide de polissage 21 en contact avec la paroi. Lors de l'étape de polissage chimique S2, le liquide de polissage 21 est fluidifié à l'intérieur du canal d'écoulement 14. Lors de l'étape de polissage chimique S2, il est préférable que le liquide de polissage 21 à l'intérieur du canal d'écoulement 14 soit fluidifié à l'aide d'un dispositif comportant : un réservoir de liquide de polissage 22 destiné à stocker le liquide de polissage 21 et à contenir la turbine 10 en son sein ; un canal 23 à travers lequel le liquide de polissage 21 stocké dans le réservoir de liquide de polissage 22 est fourni sous pression ; et une partie d'alimentation 24 qui constitue une extrémité terminale du canal 23, et qui fournit le liquide de polissage 21 à un orifice d'entrée 141 de chacun d'une pluralité de canaux 14.
(JA) 研磨等により平滑化する工程に要する時間を抑えて、インペラの成形から平滑化までを含めた製造効率を改善すること。本発明のインペラの製造方法は、熱溶融積層造形によりインペラ10を成形する成形工程S1と、インペラ10が有する流路14を区画する壁15を研磨液21と接触させて研磨する化学研磨工程S2とを備える。化学研磨工程S2では、流路14内の研磨液21に流動を与える。化学研磨工程S2では、研磨液21を貯留し、インペラ10を収容する研磨液槽22と、研磨液槽22内の研磨液21を圧送する経路23と、経路23の終端を構成し、研磨液21を複数の流路14の各々の入口141に供給する供給部24とを備えた装置を用いて流路14内の研磨液21に流動を与えることが好ましい。
