Experiment Study of Anticorrosive-wear about Tube and Rod Friction Pair in the Pumping Well;

Experimental study on electrode potential and electrochemical corrosion of four kinds of ordinary materials selected under different sewage environments was discussed,in order to ascertain the influence of electrochemical corrosion on corrosive-wear of oil tube and pumping rod.

Study the corrosive-wear rules of the oil tube and pumping rod in different environment can guide technologists through the selection of the suitable tube and rod materials.

But for those turbines in silt-laden river, because of the wear by sediment and the interaction between the wear and cavitation, the setting height of turbine would influence the investment and safe and stable operation of the hydropower station.
