项目背景分析
中海石油天野化工( 集团) 有限责任公司现有1 套年产 300kt 合成氨、 520kt 尿素生产装置, 1 套年产200kt 甲醇生产装置。其中, 尿素装置尿素溶液从造粒塔冷却后形成的尿素颗粒经皮带系统输送到散料库, 再经皮带系统输送到包装楼进行包装, 通过输送皮带送往站台装车。
原有的皮带控制系统电路都是相当复杂的老式继电回路, 加上运行时间已达十多年, 故障发生率很高, 一旦发生故障需用很长时间来查找和排除故障点, 给检修和维护带来很大不便。
随着 PLC 在工业控制中的应用越来越广泛,PLC 技术也越来越成熟, 现已将原有的控制电路改造成由 PLC可编程控制的电路, 来改变目前输送系统存在的问题。
