During safety inspections, many companies encounter a troubling scenario: the combustible gas detectors installed in the field do not match the actual gas that could leak. What makes the situation even more challenging is that this discrepancy is often classified as a major safety hazard. Rectifying it can be costly and difficult. So, can gas […]

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
