摘要
Abstract
In order to test the actual operation condition of cylindrical valve in hydro-power station with long-distance water delivery system, the change of state variables of the unit under partial load in the dynamic closing process of the cylindrical valve was detected by the field test method. The dynamic closing process of cylindrical valve was simulated numerically on the basis of the test data. The comparison results showed that the two were highly consistent, which proved the accuracy of the numerical sim-ulation. The prediction for the extreme modes of cylindrical valve closing process by the numerical simulation method indicated that the pressure at the inlet of the spiral case in 100% load met the requirements of the contract. It provides basis for ensuring the safe operation of mechanical and electrical equipment of hydropower stations.关键词
