Because of the working environment of the mine submersible pump, the pump must be antiseptic and wear-resistant. And anticorrosion can start from the following aspects.

1, paint anticorrosion. This is one of the most common decorative and anticorrosive methods for mine submersible pumps. The operation is also simple, in time the shell of the mining submersible pump, and the interior of the impeller pipe to apply a layer of wear-resistant paint. The paint can isolate the metal pump shell from the air, thus avoiding the oxidation of the metal to oxygen.

2. The metal coating of the mine submersible pump is anticorrosion. The anticorrosion method is also common. It includes the gilt we usually say. It is a kind of anticorrosion technology. The whole mining submersible pump is electrified and placed in a chemical solution containing zinc, and the zinc will be replaced. What's happening here is the displacement reaction of electrons. At the same time, through the length of the time to control the thickness of the galvanized layer, so that it can play a dual effect of anti-corrosion and wear resistance.

3. Increase the anticorrosion of the mine submersible pump through alloy technology. The anticorrosion of the alloy here is based on the acidity and alkalinity of the liquid to be transported. Different solutions are actually required for different alloys. High chromium alloy is actually a better kind of wear-resistant material, but if it is an acid liquid, the alloy is still not good. So it depends on the situation.

4, pay attention to the corrosion of the welding interface. Many parts of the submersible pump are welded together by welding, and the welded joints are fluffy. It is the most easy to release corrosion in relatively cast metal. So we must deal with special emphasis.
