Coursera 课程"校准、安装与调试仪表" 学习总结： 本课程深入介绍了工业设施项目生命周期中仪表工程的关键阶段，从规划到维护。 * **规划**: 强调安全性的首要地位，通过 HAZOP 等风险评估，并规划好完工优先级、文档、人力和工具。 * **设计**: 关注设计依据和 P&ID 图。 * **安装**: 仪表工程师和主管需标记仪表位置、接线盒和电缆路由，并根据可用工作面展开安装。 * **预调试**: * **校准**: 确保仪表读数准确，通过与参考标准比较实现。 * **回路检查**: 包括冷回路测试（检查接线完整性）和热回路测试（通过模拟控制器和 I/O 进行功能测试）。 * **单体测试**: 验证仪表安装后是否完好。 * **工厂验收测试 (FAT)**: 在工厂进行的控制系统测试。 * **工厂验收测试 (SAT)**: 由供应商或调试团队在现场进行。 * **现场集成测试 (SIT)**: 确认设备作为一个系统正常运行。 * **调试**: * **冷调试**: 在未引入工艺介质前进行的测试，如联锁和紧急停机测试、控制系统顺序检查。 * **湿调试**: 引入安全流体（如水或溶剂）后进行的测试，如带闭环运行泵。 * **试运行**: 引入设计工艺介质，使系统和子系统运行，如带闭环运行泵。 * **启动**: 整个工厂进入运行状态，引入工艺介质并建立工艺条件，以生产产品。 * **初期运行**: 工厂处于连续运行状态，进行微调并准备性能测试。 * **维护**: 涵盖预防性维护、纠正性维护、预测性维护、应急维护和翻新维护。 课程强调了安全、准确的执行和各阶段的协同合作对于项目成功的重要性。
It is so important for any Engineer deal with industry facility to understand the phases of project life cycle Project life cycle of Process Field Instrumentation1 Planning2 -Design 3- Installation4 -Pre- Commissioning 5- commissioning 6-Startup 7- Initial Operation 8 - MaintenancePlanning With out planning you will not be able to carry out a plant safely and in timeWhich items you have to plane for fast , safe and successful plant execution •Risk assessment (•Safety is the first priority during any process eg. "HAZOP" (Hazard and operability analysis ) It is to identify and assess risk)•Completion priority•Documents•Manpower•ToolsDesign•Design basis•"P & ID" designInstallation•Initially, Instrumentation Engineers and supervisors mark the:1.location of Instruments.2.Junction boxes.3.Identify cable routing.• Locations will be marked on nearby structures, vessels, etc.•Civil foundations, structural, mechanical static equipment will be installed first.•Based on the work front available to install Instruments, the Instrumentation team will start their activities.Pre- CommissioningConfirm calibration settings , ranges Calibration is adjustment to ensure that the instrument give accurate reading.Its done by comparing the readings on an instrument with reference one.Cold and Hot loop check Cold loop testing is done without powering up, ie the wiring integrity is tested through loop resistance and continuity check.Hot loop test is done by simulation of the automation controller (PLC, DCS) and the I/O, Functions etc. are tested.Stand alone tests confirm no damage after installation• FAT Factory acceptance testing (manufactory) is simply a test for a newly manufactured control system that takes place at your factory or your workshop before you ship the control panel to the customer.• SAT Site acceptance testing (vendor or commissioning team)• SIT Site integration testing (confirm equipment functions as a system)CommissioningUsually it is the phase when design process fluids are introduced to the systems and sub systemCold commissioning •Dry commissioning: tests and procedures without fluids yet introduced to the plant•Example activities: Interlock and emergency shut-down tests•Control system sequence checks•Wet commissioning: tests and procedures with safe fluid (water or solvent) has been introduced into the systems and sub-systems•Example activities "running pumps with closed loops"Hot Commissioning "Live commissioning"•Design process fluids are introduced to the systems and sub-systems•Example activities "running pumps with closed loops"Startup The phase in a project where the entire plant (all systems and sub-systems) are taken into operation, Process fluids are introduced and process conditions are established with the intent of making productsInitial operation The entire plant is running in continuous operation, fine-tuned and prepared for the performance test.Maintenance •Preventive Maintenance •Corrective Maintenance•PREDICTIVE Maintenance•EMERGENCY Maintenance•RENOVATION MaintenanceI hope you will enjoy learning.
