摘要
针对除尘系统中采用的传统顺序控制器的电磁阀损坏及控制器内部触点损坏难以判断,喷吹时间控制不精确等缺陷,采用增设真空压力传感器、正压压力传感器和PLC模块的改造,解决了除尘效果差及无法提供除尘器故障来源的问题。通过现场调试应用,验证了该方法具有较好的控制效果。
In the dust-removal system, traditional mode is adopt sequence controller, in this way electromagnetic valve break or contact break is difficult to judge, blowing time inaccurate, use vacuum pressure sensor, positive pressure sensor and PLC module control project to solve remove dust badly and unable provide the break source. The application process indicated that the technique is improved greatly in the practical work.
