恒压喷灌系统水泵综合调节的研究

A Study on Comprehensive Regulation of Pump in Constant-pressure Sprinkler System

在恒压喷灌系统允许的压力变幅内,水泵的实际工作区往往偏离其高效区,因而降低了水泵的运行效率,增大了系统能耗。为此,本文提出了利用水泵变径或变速调节的具体计算方法和解决的措施。

The actural working area of pump always deviates from the efficiency area, the running efficiency of pump is reduced and energy charge is raised when the pressure in a constant-pressure sprinkler system fluctuates in a permit range. In view of these facts, this paper presents a calculation procedure and the way to solve this problem through changing the diameter and velosity of a pump.
