The four anti-corrosion measures of deep well submersible pump

 To control groundwater well pipe corrosion mainly from two aspects. One is to improve the tubing corrosion resistance, the use of the material corrosion resistance. The second is to remove or suppress some corrosion factors. Generally have the following anti-corrosion measures:

1. Made of high quality materials, good corrosion resistance pipe, connecting screw, wire rope, prolong the service life will be multiplied. Same metal material with smooth surface, as far as possible need not rough; No hardening by annealing. Stress concentration in welding mouth prone to corrosion, and should be avoided in the production and installation.

2. Coating (plating) protective layer on the surface of tubing coating protective layer (plating) has the following characteristics: electric insulation, integrity, and persistence, the besmear after material has certain adsorption and intensity, and non-toxic and economy.

3. Replace the screw Deep well submersible pump well pipe connecting screws, every year to wellhead repair replacement, had better use galvanized screw connection. Wire rope oiled or plastic pipe set.

4. To strengthen the control in a large number of heavy calcium carbonate precipitation area, try to take various measures to reduce the hydraulic jump value for water Wells, reduce feed speed, increase the filter size, increase the water area, when water demand determine the little smoke, fill gravel diameter of the upper limit.
