　　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%。 [5]

　　实现电机软启动

　　电机硬启动不仅会对电网造成严重的冲击，而且会对电网容量要求过高，启动时产生的大电流和震动对挡板和阀门的损害极大，对设备、管路的使用寿命极为不利。而使用变频器后，变频器的软启动功能将使启动电流从零开始变化，值也不超过额定电流，减轻了对电网的冲击和对供电容量的要求，延长了设备和阀门的使用寿命，同时也节省设备的维护费用

　　Application in improving process level and product quality

　　Frequency converter can also be widely used in transmission, lifting, extrusion, machine tool and other mechanical equipment control fields. It can improve the process level and product quality, reduce the impact and noise of equipment, and extend the service life of equipment. After adopting frequency conversion speed regulation control, the mechanical system is simplified, and the operation and control are more convenient. Some of them can even change the original process specifications, thus improving the function of the whole equipment. For example, in the setting machine used in textile and many industries, the temperature in the machine is adjusted by changing the amount of hot air. The circulating fan is usually used for conveying hot air. As the fan speed remains unchanged, the amount of hot air sent can only be adjusted by the damper. If the damper fails to adjust or is not adjusted properly, the setting machine will be out of control, thus affecting the quality of finished products. When the circulating fan is started at high speed, the wear between the drive belt and the bearing is very severe, making the drive belt a consumable. After adopting frequency conversion speed regulation, the temperature can be adjusted by the frequency converter to automatically adjust the speed of the fan, which solves the product quality problem. In addition, the frequency converter can easily start the fan at low frequency and low speed, reduce the wear between the drive belt and the bearing, prolong the service life of the equipment, and save 40% energy.
