永磁驱动调速技术在引风机改造中的应用
摘要
通过对液力耦合调速器、变频调速器和永磁驱动调速器优缺点的比较
决定采用永磁驱动调速技术对某电厂锅炉引风机进行改造
并对改造后的经济效益和安全性能进行了分析。改造后
机组运行振幅下降83%
噪音降幅35%
机组每年可节省费用60.9万元
不到2年就可收回投资
风机经济性、安全可靠性显著提高。
Abstract
By analyzing the advantages and disadvantages of the variable-frequence governor
hydraulic coupling governor and the permanent magnet drive speeder
the permanent magnet speed control technology was applied to conduct retrofit for induced draft(ID)fans in boiler of a power plant.After the transformation
the unit can save 609 000yuan per year
meaning the investment can be recovered within less than two years;the vibration amplitude of the air fan decreased by 83%
