谈生活及消防水泵如何选型

How to select water pumps for life and fire protection

水泵选型的主要依据是Q(流量)、H(扬程)、η(效率)。把这几个技术参数的计算公式进行归纳总结,选择水泵时,可以根据具体情况,决定使用其中的哪个公式进行计算,汇总罗列了一些常用的数据以方便取用,并分别阐述了几种有代表性的水泵、泵组以及它们之间相互关系和选型要点。

The main basis for the selection of water pump is Q(flow),H(head)and flow rate(efficiency).In this paper,the calculation and determination of these technical parameters are summarized,and when the water pump is selected,which of these parameters can be used to calculate according to the specific conditions,some commonly used data are listed in this paper to be used conveniently.Several representative water pumps,pump sets and the key points of their selection and selection are described.
