Prevention of corrosion of deep well submersible pumps

The control of the corrosion of groundwater by well pipes mainly starts from two aspects. The first is to improve the corrosion resistance of pipes and use materials with good corrosion resistance. The second is to remove or inhibit some of the factors that cause corrosion. There are generally the following anti-corrosion measures.
1. The use of high-quality materials with good corrosion resistance, connecting screws, and copper wire ropes can multiply the service life. The same type of metal material should have a smooth surface and should not be rough; it should be annealed and not hardened. Welds at stress concentration sites are prone to corrosion and should be avoided during production and installation.
2. The coating (plating) protective layer of the coating (plating) protective layer has the following characteristics on the surface of the pipe: electrical insulation, integrity and durability, the coated material has a certain degree of adsorption force and strength, and is non-toxic and economical.
3. Replace the well pipe connection screws of the deep well submersible pump with screws. Every year, the wellhead must be repaired and replaced. It is best to use galvanized screws for connection. Wire ropes are oiled or covered with plastic tubes.
4. Strengthen the regulation in the heavy precipitation of heavy calcium carbonate areas as much as possible to take various measures to reduce the water supply pipe wells hydraulic jump, reduce the water inlet speed, increase the filter diameter, increase the water intake area, when the water demand is determined using small pumping, fill The upper diameter of the gravel is used.
