A pressure gauge operates by using the elastic deformation of sensitive elements inside the gauge (such as Bourdon tubes, diaphragm capsules, or bellows). The pressure-induced deformation is transmitted to the pointer through the movement mechanism inside the gauge, causing the pointer to move and display the pressure. When selecting a pressure gauge, we can consider […]

1. Introduction Atmospheric and vacuum distillation units are critical components in petroleum refining, primarily responsible for the initial separation and processing of crude oil. Due to their operation involving high temperatures, high pressures, and flammable substances, these units are susceptible to significant fire and explosion risks. This article analyzes the potential hazards and proposes effective
In a recent industrial installation, the reboilers of a distillation column were configured to use steam pressure control. However, concerns were raised regarding the stability of incoming steam pressure, leading to the suggestion of switching to flow control. This proposal included the addition of a steam flowmeter and updating the control scheme. Since this involves

Steam plays an important role in industrial production and life. Its high efficiency, environmental protection and stability make it one of the indispensable energy sources in modern society. Usually, according to the physical state, we divide common steam into two categories: saturated steam and superheated steam. Saturated Steam Saturated Steam refers to the state in
In the realm of industrial automation and control systems, two key components often come into focus: SCADA (Supervisory Control and Data Acquisition) and HMI (Human-Machine Interface). While these systems are interconnected and sometimes overlap in functionality, they serve distinct purposes within industrial operations. Understanding their differences is essential for implementing efficient and effective control systems.
