摘要
风机运行电费是一笔不小的费用,从节能方面考虑,在既满足目前生产的条件下可进行变频改造。改为变频器控制预计满足正常生产时的电流大约为电机额定电流的50%,改变的电流变化不大,只是电压变化。如果改为变频器控制则必须将风门调节阀全部开启,通过变频器控制转速来达到风量的调节。同时采用通过无级调频实现风量的无级调整,有效地改善引风机阀门调节不当造成的风机喘振现象,对炉压调整极为方便。
The operation of the wind turbine is not a small cost, from the aspect of energy conservation, in both meet the current production conditions can be carried out frequency conversion. Change to inverter control is expected to meet the normal production of the current is about 50% of the rated current of the motor, change the current change is not, only the voltage change. If you change the frequency changer control must be air valve fully open, to achieve volume controlled by frequency converter speed regulation. At the same time by stepless frequency to achieve the stepless adjustment of air volume, effectively improve induced draft fan valve regulating improper fan surge phenomenon and the furnace pressure adjustment is very convenient.
