Corrosion of stainless steel deep well pump

The stainless steel deep well pump is a water lifting device which works directly with the motor and the water pump. It has the advantages of simple structure, high unit efficiency, low noise, safe and reliable operation and easy installation and maintenance. It is suitable for extracting water from deep wells, hot water wells and oceans. It can also be used in rivers, reservoirs and aqueducts. It is mainly used for farmland irrigation and human and livestock water in plateau mountainous areas. It can also be used in cities, factories, railways, mines and construction sites. Drainage use.

The control of groundwater on deep well pump corrosion mainly from two aspects. One is to improve the corrosion resistance of the pipe, the use of good corrosion resistance of the material. The second is to remove or inhibit some of the factors that produce corrosion. Generally have the following 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 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, after coating the material has a certain adsorption and strength, and non-toxic and economical.

3. Replace the screw deep well pump well pipe connection screw, every year to make wellhead maintenance replacement, preferably with galvanized screw connection. Wire rope coated with oil or plastic tube.

4. Strengthen the regulation and control Heavy calcium carbonate precipitation in the region, as far as possible to take various measures to reduce the value of water supply pipe wells jump to reduce the water rate, that is, increase the filter diameter, increase the water area, when the water required to determine the use of small pumping The upper and lower limit of the diameter of the gravel.
