一、概述自“全国调速水泵供水节能技术研讨会”召开以来,在全国各地对变频调速供水装置的研究和试验已取得比较理想的成果,例如:用一台变频器循环控制多台水泵软启动变频调速供水,对建筑小区或建筑群给水系统定压点的选择确定为最不利点定压变量供水,变频调速水泵的变频调速范围限定在1/4～4/4范围内的关系,变频调速供水泵与高位水箱、气压罐等的关系等等方面都有比较明
First, an overview From “” national speed pump water supply energy-saving technology seminar "has been held in all parts of the country on the frequency control water supply device research and experiments have achieved more satisfactory results, for example: with a frequency converter cycle control and more Water pump soft-start frequency control water supply, the building plot or building water supply system set the pressure point to determine the most unfavorable point of constant pressure variable water supply, variable frequency speed pump frequency control range limited to 1/4 ~ 4/4 The relationship between the scope of frequency control pumps and high water tanks, pressure tanks and so on the relationship between the more obvious
