介绍了冷轧酸洗液压泵站的组成和油箱液位控制原理,由于液压泵站油箱液位仅用4个液位开关进行显示和控制连锁,已经无法满足日常维护点检、油耗管理、清洁生产的功能要求。对酸洗液压泵站进行液位控制功能改造,通过增设硬件、PLC软件编程、HMI画面编程、调试与改进逐步实施,完成酸洗液压泵站液位控制功能改造。方便日常维护点检,故障时快速切断系统、益于油耗管理、实现降低成本的目标,达到了预期效果。
The composition of cold-acid pickling hydraulic pump station and the principle of tank level control are introduced. As the liquid level in the hydraulic pump station is only displayed and controlled by 4 liquid level switches, it has been unable to meet the requirements of daily maintenance inspection, fuel consumption management and cleaning Functional requirements for production. The pickling hydraulic pump station level control function transformation, through the addition of hardware, PLC software programming, HMI screen programming, debugging and improvement of the gradual implementation of the completion of pickling hydraulic pump station level control function transformation. It is convenient for routine maintenance and inspection, and the system can be cut off quickly in the event of failure, benefiting the management of fuel consumption and achieving the goal of reducing costs, achieving the expected result.
