Deep well submersible pumps in the water how should we control the underground water corrosion of the well pipe it? Today, we are the Shanghai submarine pump manufacturers and we say what measures of anti-corrosion.
The first is to enhance their own, improve the corrosion resistance of the pipe, the use of anti-corrosion properties of good materials.
The second is to remove or suppress some of the factors that produce corrosion. How to do Here we introduce.
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 materials as far as possible the use of smooth surface, not rough; with annealing, no hardening. Stress concentration at the welded joints prone to 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 degree of adsorption and strength, and non-toxic and economical.
3, the replacement screw: deep well submersible pump pipe connection screw, the annual wellhead maintenance replacement should be made, it is best to use galvanized screw connection. Wire rope coated with oil or plastic tube.
4, to strengthen control: heavy calcium carbonate precipitation in a large number of areas, as far as possible to take various measures to reduce the water supply pipe wells jump value, lower water speed, to increase the filter diameter, increase the water area, when the water demand is small Pumping down, fill the gravel diameter of the upper limit.
