变频器的使用过程中轴流风机怎样改造才能够更节能呢？
轴流风机在启动时，电机的电流会比额定高5-6倍的，不但会影响电机的使用寿命而且消耗较多的电轴流风机变频器量.系统在设计时在电机选型上会留有一定的余量，电机的速度是固定不变，但在实际使用过程中，有时要以较低或者较高的速度运行，因此进行变频改造是非常有必要的。变频器可实现电机软启动、通过改变设备输入电压频率达到节能调速的目的，而且能给设备提供过流、过压、过载等保护功能。
轴流风机的改造对变频器的节能起很大的作用，T4-72和4-72是两种不同系列的离心轴流风机，是目前国内*常用的，而且是性能比较好的两种风机，都是原机械工业部的产品。这两种风机的性能和用途差不多，但结构上有些差别。明显的区别是：T4-72是钢板弯成的等厚度叶片，4-72是机翼型叶片。T4-72玻璃钢风机实际上就是用玻璃钢材料代替钢板按T4-72的结构和尺寸制作的风机，4-72也有玻璃钢风机。
