In fire safety design reviews for construction projects, even though the fuel storage room in a diesel generator room may not be large, it often faces scrutiny. Experienced designers often encounter a situation where an expert casually reviews the design and says, “Hey, no flammable gas detectors here?” followed by, “This poses a major safety […]

In industries such as chemical engineering, environmental protection, pharmaceuticals, municipal projects, and energy, pump selection is one of the most critical steps during the design phase. Proper pump selection directly impacts the operational safety, energy efficiency, and overall cost-effectiveness of the system. Through consultations with experienced professionals in design institutes, we have summarized the key

OverviewWhen wiring in non-explosion-proof zones, it’s crucial to prevent intersections with other areas such as explosion-proof zones, high-voltage zones, low-voltage signal zones, and water/gas pipeline areas. The primary goal is to avoid interference, mitigate safety risks like leakage or short circuits, and ensure system stability. This can be achieved through systematic design focused on physical

1. Overview of Temperature and Pressure Compensation Temperature and pressure compensation is a technique used to automatically adjust the measurement results of instruments to standard conditions, specifically 25°C and 1 standard atmosphere pressure. This is done by measuring the actual temperature and pressure on-site and using a compensation formula to convert the readings to standard

In industries where hazardous materials are handled, safety is paramount. Ensuring that all equipment is properly connected and maintained is critical to preventing accidents and protecting workers. One such vital component in these environments is the explosion-proof flexible hose, commonly used to transport fluids and gases in various industrial settings. Why Proper Connection Matters Flexible

What is Dew Point Temperature? In meteorology, dew point temperature (Td) refers to the temperature at which air, while keeping the same air pressure and water vapor content, cools down enough for the water vapor to start condensing. In simple terms, it’s the moment when air becomes “saturated with water.” When air cools down to

Introduction and Objectives Background: In industries such as chemical production, thermal power generation, metallurgy, and mining, equipment like pumps, coal mills, and turbines often generate high-frequency vibrations. These vibrations pose significant risks to the reliability of instrument wiring. Loose, improperly connected, or broken wires can cause measurement signal fluctuations and distortions, leading to false alarms,

1. DCS System Inspection Regular Inspections: Conduct inspections twice a day at designated times. Dust Removal: Clean the control cabinet and operating desk exterior weekly. Clean the interior components like computers, control stations, and fans every week. Replace the cabinet filters bi-weekly. Inspect fans daily for proper operation and replace damaged units promptly. Inspection Content:

Instrument calibration is a critical process to ensure the accuracy and reliability of measurement equipment in any business environment. However, completing the calibration itself is not the end of the process. Two essential steps must follow to ensure the results are properly utilized and documented. These steps are recording and archiving calibration results and updating

In the era of industrial automation, where systems are becoming larger and more intelligent, the I/O modules in Distributed Control Systems (DCS) — which act as the “nervous system” linking the field to the control center — are facing unprecedented challenges. The expansion of plant size leads to a dramatic increase in signal points, while
