DXM-340W隔离器
变频器节能主要表现在风机、水泵的应用上。风机、泵类负载采用变频调速后,节电率为20%~60%,这是因为风机、泵类负载的实际消耗功率基本与转速的三次方成比例。当用户需要的平均较小时,风机、泵类采用变频调速使其转速降低,节能效果非常明显。而传统的风机、泵类采用挡板和阀门进行调节,电动机转速基本不变,耗电功率变化不大。据统计,风机、泵类电动机用电量占全国用电量的31%,占工业用电量的50%。在此类负载上使用变频调速装置具有非常重要的意义。目前,应用较成功的有恒压供水、各类风机、空调和液压泵的变频调速。
在自动化系统中应用
由于变频器内置有32位或16位的微处理器,具有多种算术逻辑运算和智能控制功能,输出频率精度为0.1%~0.01%,且设置有完善的检测、保护环节,因此,在自动化系统中获得广泛应用。例如:化纤工业中的卷绕、拉伸、计量、导丝;玻璃工业中的平板玻璃退火炉、玻璃窑搅拌、拉边机、制瓶机;电弧炉自动加料、配料系统以及电梯的智能控制等。变工艺水平和产品质量方面的应用频器在数控机床控制、汽车生产线、造纸和电梯上的应用。
在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%。
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,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,大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。
