Have you ever stood in front of the large screen in a control room, watching numbers and flashing symbols, but had no idea what they meant? Don’t worry! This article will help you understand the soul of factory automation—control loops. What is a Control Loop? In industrial control systems (DCS/PLC), each control loop functions like […]

Responsibilities of Construction Personnel Summary: After the completion of the project, conduct a technical and quality summary. Work Instructions: Attend the design review and technical handover meetings. Under the project manager’s direction, provide technical handovers to construction personnel. Execution: Strictly follow the construction and acceptance standards. Ensure the inspection system is followed. Adhere to the

Many people think “aging” happens only after several years of use. In reality, the aging of polymer materials begins the moment they are formed. Engineers often encounter: Yellowing or discoloration Loss of mechanical strength Surface roughening or cracking Electrical performance drifting Mold or surface contamination These are not simply “process issues.” They are manifestations of

In the powder chemical industry, combustible dust explosions are rare but highly destructive “black swan” events. According to Dust Safety Science, between 2016 and 2020, the United States averaged approximately 31.8 dust explosions per year (excluding dust fires), resulting in numerous injuries and significant economic losses annually. I. A Massive Explosion Triggered by a Small

Instrument technicians play a vital role in ensuring the proper operation of industrial systems. To become proficient in this field, the foundation lies in conducting thorough and systematic routine inspections. This guide details the essential steps, considerations, and best practices for effective inspection and maintenance. 1. Establish a Systematic Routine Instrument technicians typically oversee specific

I have gradually come to realize that, when it comes to PID tuning methods, the most important factors are not performance, but simplicity and universality. The Lambda tuning method, after a series of improvements, possesses characteristics that are more suitable for engineering applications. Unlike traditional PID methods, Lambda tuning does not use derivative action, instead

In the world of piping systems, PTFE (Polytetrafluoroethylene) is almost a “star material.” Whether it’s flange gaskets or valve seals, it’s frequently used in various applications. However, one recurring question often arises: “What is the maximum temperature PTFE can withstand?” Some claim it’s dangerous to use beyond 150°C, while others confidently say it’s safe up

In the implementation of Distributed Control Systems (DCS) projects, three critical tests—Factory Acceptance Testing (FAT), Site Acceptance Testing (SAT), and Field Integration Testing (FIT)—play vital roles at different stages of the project. These tests ensure that the DCS system operates smoothly and meets the user’s needs. While each test is interrelated, they each focus on

In Safety Instrumented Systems (SIS), Safety Integrity Levels (SIL) are crucial for ensuring that Safety Instrumented Functions (SIF) meet the necessary risk reduction requirements. This article focuses on the Layer of Protection Analysis (LOPA) method, which is widely used to determine the appropriate SIL for a specific SIF in industrial applications. Introduction to Layer of
