工业锅炉风机在设计时往往是按最大工况来考虑的,在实际使用中风机则需要根据实际工况进行调节。传统的做法是用开关风门、阀门的方式进行调节。这种调节方式增大了供风系统的节流损失,在启动时还会有启动冲击电流,且对系统本身的调节也是阶段性的,调节速度缓慢,使整个系统工作在波动状态;而通过在锅炉风机上加装变频调速器则可一劳永逸的解决好这些问题,可使系统工作状
Industrial boiler fans are often designed according to the maximum operating conditions to consider, in practice, the fan needs to be adjusted according to actual conditions. The traditional approach is to use the switch damper, the valve way to adjust. This adjustment mode increases the throttling loss of the air supply system, and at the time of starting, there will be an inrush current, and the adjustment of the system itself is also phased, and the adjustment speed is slow, so that the entire system operates in a fluctuating state; The installation of frequency converter on the boiler fan can solve these problems once and for all, can make the system work
