摘要
对离心泵在定扬程变频调速状态下轴功率的相应变化进行了数学分析,并在对离心泵常规特性曲线数学拟合的基础上,给出了该变速状态下轴功率的计算公式,该计算方法简便、快速,且计算精度较好,可用于离心泵工况分析和节能效益的评价。
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.
