| Abstract: | The variation of the shaft power of the centrifugal pumb in the condition of an invariable lift, a fluetuant frequency and an adjustive speed were analyzed. The formula that could calculate the shaft power in the condition of fluctuant speed was brought forward based on the analogy of the conventional pump characteristic curve. The method is simple, fast and higher accuracy. It can be used to analyze the working condition of the centrifugal pumb and estimate the effect of energy conservation. |
