Cavitation and Hydraulic Abrasive Stability of Metals in Hydraulic Turbines (Selected Articles)

摘要

In the planning of new hydroelectric power plants located on mountain rivers it is necessary to estimate the abrasive ability of river deposits and degree of their danger for hydroturbines. Such appraisal can be made on the basis of comparison of conditions of deposits on the planned hydroelectric power plant and any others close to it in pressure and composition of deposits of an operational hydroelectric power plant equipped with analogous turbines, under the condition that on latest hydroelectric power plants there is well studied the wear of turbined and conditions of deposits. Using the proposed method, a forecast can be made of the degree of danger of erosional destruction under influence of deposits contained in river water both on the whole for turbines made from carbon steel of newly planned hydroelectric power plants and for their individual parts.
