摘要
针对多数煤矿压风机能力过剩,存在“大马拉小车”现象,为了实现压风机的节能运行和恒压供风,介绍一种PLC控制的煤矿压风机变频调速系统。论述了系统的结构、工作原理、软硬件配置及其在实际运行中的节能效果。
In many mines, the ventilation capacity of air compressors is over supplied and its work likes a strong horse draws a small cart. In order to save energy in the operation of air compressors and ensure air supply with constant pressure, this paper introduces a control system for mining air compressors in which frequency converter is controlled by PLC. System structure, working principle, software and hardware configurations and power saving result are discussed in the paper.
