Abstract: the selection of so-called pump calculation is actually estimation (many formula itself is estimate of the estimated the careful points), some consideration of your overall content is accurate calculation. Include water pump selection index, the water pump head, frozen water pump simple estimation method of head practical estimation method, the water pump head design, etc.

摘要：所谓水泵的选取计算其实就是估算（很多计算公式本身就是估算的），估算分的细致些考虑的内容全面些就是精确的计算。包括水泵选型索引，水泵扬程简易估算法，冷冻水泵扬程实用估算方法，水泵扬程设计等。
