How deep well submersible pumps prevent corrosion

Control of groundwater corrosion of the well pipe mainly from two aspects.
First, improve the corrosion resistance of pipe, the use of good corrosion resistance of the material. Second, remove or suppress some of the factors that produce corrosion. Generally have the following deep well submersible pumps anti-corrosion measures:
1. The use of high-quality materials, good corrosion resistance of the pipe, connecting screws, copper wire rope, can be doubled to extend the service life. The same kind of metal material as far as possible the use of smooth surface, without rough; with annealing, without hardening. Stress concentration at the welding port is easy to produce corrosion, in the production and installation should be avoided.
2. Coating (plating) protective layer in the pipe surface coating (plating) protective layer has the following characteristics: electrical insulation, integrity and durability, coated material has a certain adsorption force and strength, and non-toxic and economical.
3. Replace the screw with the deep well submersible tubing connection screw, every year to mention the wellhead repair replacement, preferably with galvanized screw connection. The steel wire is coated with oil or plastic.
4. Strengthen the regulation of heavy calcium carbonate in a large number of precipitation areas, as far as possible to take various measures to reduce the water supply pipe shaft water level, reduce the water speed, that is, increase the filter caliber, increase the water area, when the water demand to determine the use of small pumping Drop, gravel diameter using upper limit.
