More Information
Summary:A method for detecting efficiency of individual pump of parallel centrifugal pump station is suitable for parallel arranged centrifugal pumps of the parallel type centrifugal pump station. The detection method includes: obtaining flow test values and motor output power test values associated with each other from the factory performance test table of the centrifugal pump; performing a regression analysis on the flow test values and the motor output power test values to obtain regression coefficients, thereby establishing a performance equation based on the regression coefficients; calculating a motor output power calculated value according to measured values and a motor efficiency test value; and calculating a flow rate calculated value by substituting the motor output power calculated value into the performance equation.
