According to the common method of the performance calculation of centrifugal pump , the author calculated the head and power of the pump , showed the way to get the pressure of the outlet 根據(jù)一般離心泵的計算方法,結合螺旋型離心泵的特點,論文計算了泵的揚程和功率,給出了在已知流量和進口壓力的情況下求得出口壓力的方法。
The pressure of pressure stabilizing pump will be settled on the basis of its delivery head which is not calculated but determined by the delivery head of main fire pump as the function of it is to stabilize the pressure inside the fire water system 穩(wěn)壓泵的壓力設定值決定于穩(wěn)壓泵揚程,穩(wěn)壓泵的揚程一般不另行計算,而是采用消防主泵的揚程,其原因在于設置穩(wěn)壓泵的目的是使消防給水管網(wǎng)的水壓穩(wěn)定。
