CONSTRUCTION MATERIALS FOR PUMPS FISH CANNING PRODUCTION
The nature of cavitation erosion wear pumps fish canning industries and selected materials for the flow of the pump, pumping sodium chloride solutions of different concentrations. The analysis of the causes of the deterioration of running these pumps to perform laboratory tests and on this basis offer durable construction materials for the manufacture of their parts. The results of potentiostatic studies on installation with MSW showed that the presence of chlorides in the water corrosion resistance of metals decreases sharply (for carbon steels to order). The intensity of corrosion is not a corrosion resistant alloy with a maximum content of 3-5% in a solution of salt, which is caused by a decrease in oxygen solubility. Therefore, the authors suggested the details of a flowing part of pump, pumping solutions of sodium chloride, it is advisable to be made of titanium and high-chromium alloys.
