GALVANIC-CORROSION PREVENTING STRUCTURE OF MAIN SHAFT IN ROTATING MACHINE IN WATER

摘要: PROBLEM TO BE SOLVED: To provide an galvanic-corrosion preventing structure of a main shaft in rotating machine water, which can be applied to non-electroconductive impeller using resin, rubber, or the like, and is effective highly corrosive environment such as chlorine sterilization discharge tank. SOLUTION: The 2 provided derivation part at load side 1 made stainless steel with fitting screw 5, through toroidal sacrificial anode 3 clip plate 4 for loosening, characterized that ferrous material rest potential slightly baser than 1.
