应用变频技术节能效果明显。由于变频器直接改变电源频率而改变电机转速,没有额外机械损失,我们知道,在应用最广泛的泵与风机类型的负载中,流量与电机转速成正比,压力与转速平方成正比,而消耗功率则与转速立方成正比。当流量由**降至80%时,则消耗功率降至15%,即使考虑到风机或泵的效率降低,变频器本身的效率,以及其他因素,节能率也将达到30%以上,而在实际应用中,考虑到风机或泵的余量以及负荷变化的范围,节能效果一般可达到30%一70%.因此,节能效果非常明显。变频器调节平稳、准确。
对于流体,为了调节流量,通常采用阀门或档板,实际流量小于额定流量,此时节流损失往往很大,而当流量很小时,除了节流损失以外,阀门或档板往往开度很小,很容易造成管路振动或流量抖动。而对于象给粉机、给煤机等设备的控制通常采用机械变速、电磁变速甚至不变速等方法,往往存在调节不线性,调节不均匀等问题。采用变频器技术后,由于直接改变电机转速,运一转平稳,调整准确。变频器可靠性高,故障率低,减少设备事故。在锅炉给粉机中,以前采用滑差电机调速,经常发生故障,影响了机组安全运行,采用变频器技术后,由于取消了滑差电机,拆除了最容易发生故障的部件,使得整体可靠性大大提高。
