液体电阻调速技术在电厂引风机上的应用

Application of Liquid Resistance Speed Control Technology in Induced Draft Fan of Power Plant

液体电阻调速技术,改变了引风机采用定速运行,依靠调节入口档板来调节风量,为通过改变转差率来实现改变电机的转速,实现软启动,节能效果明显并且投资少、占地小、运行平稳安全。改造应注意的关键问题是转子改为绕线式并且要有可靠的水源。

By using the liquid resistance speed control technology,the constant speed operation mode of the induced draft fan,in which the air flow is adjusted by regulating the damper in the inlet,was changed.The liquid resistance speed control technology controls the motor rotating speed by changing the slipping;the technology can realize the soft starting of the motor and can realize energy conservation.This technology only needs small investment and occupied space,and can realize stable and safe operation.The key ...
