Abstract: front page image
(EN)Provided is a structure that prevents corrosion from occurring and progressing between materials even when a casing and a casing ring (liner ring) (19) are of dissimilar metal materials and that prevents erosion by way of cavitation caused by leaks that pass through gaps between the casing and the casing ring due to corrosion progression. An erosion preventing structure near the location where the casing faces an impeller (9) comprises the casing, the casing ring (19) that is disposed in the casing and faces the impeller (9), and an electrical insulating member (17A) that is provided between the casing and the casing ring (19).
(FR)L'invention concerne une structure qui empêche la corrosion de se produire et de progresser entre des matériaux même quand un carter et un anneau de carter (anneau d'étanchéité) (19) sont faits de matériaux métalliques différents et qui empêche l'érosion par formation de cavités causée par des fuites qui passent dans des espaces entre le carter et l'anneau de carter suite à la progression de la corrosion. Une structure d'empêchement d'érosion près de l'emplacement où le boîtier fait face à un rotor (9) comporte ledit carter, l'anneau de carter (19) se trouvant dans le boîtier face au rotor (9), et un élément d'isolation électrique (17A) se trouvant entre le carter et l'anneau de carter (19).
(JA) ケーシングとケーシングリング(ライナーリング)19が異種金属材料であっても、互いの材料の間の腐食の発生と進展を防止すると共に、腐食の進展によるケーシングとケーシングリング間の隙間を通過する漏れ流れに起因するキャビテーションによる壊食を防止する構造を提供すること。 ケーシングとインペラ9との対向部位近傍における壊食防止構造であって、ケーシングと、当該ケーシングに設置されると共に前記インペラ9に対向するケーシングリング19と、前記ケーシングとケーシングリング19との間に設けられる電気的絶縁材17Aとを備えている。
