摘要
通过自主设计与实施，采用西门子s7—300PLC替代原有控制器，提高设备稳定性，使过滤器的阻力恢复正常，空压机的入口导叶阀的控制平稳，空气吸入量达到了79000～82000m3／h的设计要求，空压机电机定子电流稳定在680A以下。有效的保证了我厂生产设备的顺利运行，为氧、氮气体用户提供了稳定的气源。
With independent design and implementation, by use of Siemens S7-300PLC instead of o- riginal controller, stability of the equipment is improved, resistance of the filter recovers, vane-guiding valve at entrance of air compressor is steadily controlled, air intake reaches designed capacity of 79000-82000mVh and current in motor stator of air compressor keeps under 680A. So we effectively ensure fluent operation of production equipment in our plant and stably supply users with oxygen and nitrogen.
