摘要:本文聚焦某漂白化学浆技改工程自动化仪表项目,深入剖析现代工业自动化仪表工程在设计管理、安装调试、设备选型等环节的典型问题。通过实证研究明确设计图纸精确性、仪表选型匹配度、控制系统集成度等核心矛盾,并创新性构建 “三维度协同管理模型”。同时,项目实践中形成的 “DCS 改造五步法”“阀门选型三校验原则” 等技术管理方法,为同类工程提供了重要参考。研究数据表明,经全过程优化管理,项目返工率可降低 37%,调试周期可缩短 42%,设备故障率下降可65%,可有力推动制浆造纸行业自动化仪表工程的发展。

Abstract:This paper focuses on the automation instrumentation project of a bleached chemical pulp technical renovation initiative, conducting in-depth analysis of typical issues in modern industrial automation instrumentation engineering across design management, installation & commissioning, and equipment selection. Through empirical research, key challenges are identified including design drawing accuracy, instrumentation type compatibility, and control system integration, leading to the innovative development of a "Three-Dimensional Collaborative Management Model". The project has also established technical management methodologies such as the "Five-Step DCS Renovation Methodology" and "Three-Verification Principle for Valve Selection", providing critical references for similar engineering projects. Research data demonstrates that through comprehensive optimization management, the project achieves: 37% reduction in rework rate, 42% shortening of commissioning cycle, and 65% decrease in equipment failure rate, effectively advancing the development of automation instrumentation engineering in the pulp and paper industry.
