水泵选型方法的研究

STUDY ON THE METHOD OF PUMP SELECT

泵与泵装置特性关系的研究表明:传统的等流量加大扬程选泵,装置达不到最高效率,水泵选型必须同时考虑装置对水泵扬程和流量损失的影响.提出了加大流量变扬程选泵的新方法。

The relationship of pump and pump system was studied.The results show that traditional method of pump select can′t make the pump system in the highest efficiency,the effects of pump system on pump lifting as well as flow capacity should be considered. Present a new method of increase capacity and change lifting for select pump. This paper also provides a adjust coefficient about the lifting and flow capacity for pump select.
