。It is known that when seawater is transferred using a rotary pump made of dissimilar metals, for example cast iron and gunmetal, the metals come into contact due to electrolytic corrosion. In order to prevent this, a zinc body that is in close contact with one point, which is conventionally predicted to occur in IJ, is installed, and this is eluted first (i.e. to protect the pump body. The h-method is adopted.

The inner circumferential surface of the zinc body 1 is exposed in the water flow.The rigid body 2 is coated with an annular zinc body 1 and is coated on both sides. , paste the sheet packing 1 and 3. Also, wrap the leak-proof packing 5 around the outer periphery of the rigid body 2 toward the zinc body.

First, since the zinc body is eluted first, it prevents the bong body from being electrolytically corroded. Also, after installation, try loosening the screw plug 4 on the outer periphery once every few months3.If water does not come out at this time, the zinc body is made of wood.
If the water leaks out, the leaching of the zinc substance will progress and the deep hole (5) will penetrate into the water flow and the flange will need to be replaced (゛Replace it with a new one.

It has the characteristic of being dark blue. Since it can be easily attached to the pump body without any machining, it can also be used for Bon 7" of the Continuing and Song Dynasties. Roughly checking the degree of elution of the corrosion-resistant flange,
il'! It is possible to inspect by simply loosening the screw plug 4 without having to pull out the li body or stop the pump.As a result, it is easy to replace the corrosion-resistant flange or increase the amount of zinc body. . ,
