空压机并网运行自稳压控制系统改造

Reform of auto-stability pressure control system of parallel running of air compressor

针对某厂空压机并网改造后运行效果不理想的问题,介绍了空压机并网运行自稳压控制系统的二次改造方案。该方案将2台空压机储气罐串联,既增大了储气罐的容量,又保证了输出的压缩空气流量和压力的可靠性、稳定性;可预先设定2台空压机的循环运行间隔时间;当一台空压机故障时,另一台空压机可自动投入工作;设有急停开关、2台空压机的启动及停止开关,可直接控制2台空压机的启动或停止运行。实际应用表明,二次改造后的空压机组运行稳定、正常。

In view of problem of non-ideal running effect after parallel reform of air compressor of a Plant,the second reform scheme of auto-stability pressure control system of parallel running of air compressor was introduced.The scheme makes series of gasholders of two air compressors,which not only increases capacity of gasholder but also ensures reliability and stability of flow and pressure of compressed air.It can preset interval time of cycle running of two air compressors,when one air compressor is in fault,the other can run automatically.It can directly control starting and stopping of the two air compressors through emergency stopping switch,starting and stopping switch of the two air compressors.The actual application showed that the air compressor unit by the second reform has stable and normal running.
