摘　　要：煤气压力的稳定性是保证球墨铸管退火质量的关键。针对煤气加压机在加压过程中经常跳闸和煤气管网压力波动较大导致机后压力不稳定的情况,介绍了采用S7-200 PLC对该系统进行变频器改造的原理和实现方法。实践证明,该技术方案是行之有效的。The stability of gas pressure is crucial to assure the quality of ductile cast iron pipes. This paper introduces the reform concept and realization method based on S7 - 200 PLC on trip fault and the wavy pressure behind engine in the process of compressing. Practices have proved that this technology scheme is available and convenient.
