空气压缩机目前在工矿企业生产中广泛地应用着。本文首先分析了空气压缩机调速系统传统控制方式存在的问题,接着阐述了变频调速控制原理,最后给出了空气压缩机变频调速系统的设计实例。实践证明,变频调速可以十分方便地进行连续调节,能保持压力稳定,大大地提高了压缩机的工作效率,节能效果明显。
Air compressors are widely used in the production of industrial and mining enterprises. In this paper, the problems existing in the traditional control methods of air compressor speed control system are analyzed first, and then the principle of variable frequency speed control is explained. Finally, the design examples of air compressor speed control system are given. Practice has proved that the frequency control can be very convenient for continuous adjustment, to maintain pressure stability, greatly improving the working efficiency of the compressor, energy-saving effect is obvious.
