The centrifugal pump is set on the base, and the base is fixed by embedded bolts. The embedded bolts are all made of conductive materials. When the centrifugal pump is used for a long time, solution leakage will occur, and the base and the embedded bolts are grounded, and the current is directed to the ground. In this process, zinc sulfate solution directly precipitates zinc, and corrodes and damages the centrifugal pump and the base. In addition, the electrolysis workshop is filled with electrolytic acid mist for a long time.
