在提高工艺水平和产品质量方面的应用
变频器还可以广泛应用于传送、起重、挤压和机床等各种机械设备控制领域,它可以提高工艺水平和产品质量,减少设备的冲击和噪声,延长设备的使用寿命。采用变频调速控制后,使机械系统简化,操作和控制更加方便,有的甚至可以改变原有的工艺规范,从而提高了整个设备的功能。例如,纺织和许多行业用的定型机,机内温度是靠改变送入热风的多少来调节的。输送热风通常用的是循环风机,由于风机速度不变,送入热风的多少只有用风门来调节。如果风门调节失灵或调节不当就会造成定型机失控,从而影响成品质量。循环风机高速启动,传动带与轴承之间磨损非常厉害,使传动带变成了一种易耗品。在采用变频调速后,温度调节可以通过变频器自动调节风机的速度来实现,解决了产品质量问题。此外,变频器能够很方便地实现风机在低频低速下启动并减少了传动带与轴承之间的磨损,还可以延长设备的使用寿命,同时可以节能40%。
