变频调速在煤气加压站恒压供气上的应用

Applications of Frequency Control in Gas Supply with Constant Pressure in Gas Compressor Stations

为了保证煤气的正常生产及居民民用煤气的稳定供给,包钢燃气厂民用煤气车间加压站对煤气加压系统进行了改造,对2台罗茨风机采用变频调速及PLC控制,实现了恒压供气。实际使用证明,改造后煤气的生产及居民民用煤气的稳定供给得到了更可靠的保证,故障率明显降低,且节能效果显著。

In order to ensure the normal productions of gas and stable supply of domestic gas,the gas compression system of gas compressor station in Domestic Gas Workshop of Gas Plant is reformed.The two Roots blowers are with variable frequency control and PLC control so that the gas supply is with constant pressure.The actual uses prove that the production of gas and stable supply of domestic gas have become more reliable,the failure rate has been decreased significantly and the effects of energy conservation are remarkable.
