Abstract
Description
ノズル15の内部、犠牲電極ユニット22の軸部22aの内部、犠牲電極22cの内部、および配管13の内部が電解液Lの流路として使用される。
犠牲電極42cは、上述した材質からなる板状部材を円筒状に加工したものでも良いし、製造時から円筒状に形成されるものであっても良い。あるいは、犠牲電極42cは、メッシュ状、パンチングメタル等の孔を有する板状部材を円筒状やC字状に丸めて加工したものでも良い。また、犠牲電極42cは平板であっても良い。犠牲電極42cが金属の場合は、犠牲電極脱落防止のために、支持部材と犠牲電極とが溶接等で結合されていても良い。挿入したとき、犠牲電極42cの端部は軸部本体42aの端部からはみ出していると、後述するように配管33の外側から犠牲電極の状態を視認することができる。
ノズル35の内部、犠牲電極ユニット42の軸部本体42aの内部、犠牲電極42cの内部、および配管33の内部が電解液Lの流路として使用される。
犠牲電極ユニット42とノズル35との間のワイヤー47を流れる漏れ電流を測定する場合には、漏れ電流と犠牲電極の有効電解面積とから電流密度を得ることができる。電流密度に応じた犠牲電極42cの消耗速度に関するデータを予め取得しておけば、計測した漏れ電流から犠牲電極の消耗度を判定することができる。
