DEVICE FOR THE CATHODIC PROTECTION OF OIL BORE-HOLE PUMPS

摘要

The invention relates to a device for the cathodic protection of oil bore-hole pumps, meant for being used in oil wells for the cathodic protection of oil bore-hole pumps. According to the invention, the device for the cathodic protection of oil bore-hole pumps ensures the cathodic protection by modifying the electrochemical potential of the environment by comprising some bushes (1) made up of alloys acting as active anodes, conically machined in the frontal areas and concentrically located on a central rod (2) by means of some centering bushes (3) and by a double conical bush (A), assembled solidly with the rod (2), by an adapter sleeve (5) and a nut (6). The rod (2) is fixed in a tubular body (7) closed in its lower side by a tapered plug (9) and placed above the pump strainer holes.
