UF C911 B108 3BHE037864R0108变频器产品特性
UF C911 B108 3BHE037864R0108 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。
UF C911 B108 3BHE037864R0108 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。
UF C911 B108 3BHE037864R0108 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。
UF C911 B108 3BHE037864R0108 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。
UF C911 B108 3BHE037864R0108 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。
UF C911 B108 3BHE037864R0108 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%
UF C911 B108 3BHE037864R0108 Frequency converters can also be widely used in various mechanical equipment control fields such as transmission, lifting, extrusion and machine tools. It can improve process level and product quality, reduce equipment impact and noise, and extend the service life of equipment.
UF C911 B108 3BHE037864R0108 After adopting frequency conversion speed control, the mechanical system is simplified, operation and control are more convenient, and some can even change the original process specifications, thus improving the function of the entire equipment.
UF C911 B108 3BHE037864R0108 For example, in setting machines used in textiles and many industries, the temperature inside the machine is adjusted by changing the amount of hot air fed into it. Circulating fans are usually used to transport hot air. Since the fan speed remains unchanged, the amount of hot air sent in can only be adjusted by the damper.
UF C911 B108 3BHE037864R0108 If the damper adjustment fails or is improperly adjusted, the setting machine will be out of control, thus affecting the quality of the finished product. The circulation fan starts at high speed, and the wear between the transmission belt and the bearing is very severe, making the transmission belt a consumable product.
UF C911 B108 3BHE037864R0108 After adopting variable frequency speed regulation, temperature adjustment can be achieved by automatically adjusting the speed of the fan through the frequency converter, which solves product quality problems.
UF C911 B108 3BHE037864R0108 In addition, the frequency converter can easily start the fan at low frequency and speed and reduce the wear between the transmission belt and the bearing. It can also extend the service life of the equipment and save 40% of energy.

使用继电器输出型PLC连接时
接触不良常带来变频器误动作,在实际接线中要注意连接可靠。
使用晶体管输出型PLC连接时
应注意晶体管本身的电压的高低、电流的大小等限制条件在其范围内,保证系统的可靠性。
变频器输入信号电路设计时
应尽量避免采用继电器等感性负载,因继电器开闭产生的浪涌电流可能引起变频器的误动作。
PLC输出开关信号进入变频器时
有时会发生外部电源和变频器控制电源之间的串扰,应注意对PLC和变频器分开接地,避免两者使用共同的接地线。
