Pressure vessels, as critical special-purpose equipment, have a design service life that directly impacts production safety. Current Chinese regulations do not prescribe a uniform, fixed retirement age for all pressure vessels; instead, they require design organizations to specify…

This article analyzes the ISO 8573‑1 classification requirements that compressed air in direct contact with food must meet, and, in conjunction with GMP and HACCP standards, elucidates key control parameters such as oil, water, particulates, and microorganisms. It…
The flow rate specified on an air compressor’s nameplate is typically given in cubic meters per minute, but this actually refers to the volumetric flow rate under standard conditions—commonly referred to as “standard cubic meters.” This article provides…
A 315 kW air compressor is a high‑power industrial device, and its actual air output is influenced by multiple factors, including discharge pressure, model type, and operating conditions. This article provides a detailed analysis of the calculation logic…
Screw compressors are widely used in industrial applications, but their starting process can significantly impact both the power grid and mechanical components. Soft‑start technology mitigates these effects by smoothly regulating the motor terminal voltage, thereby reducing inrush current…
Displacement and discharge pressure are the two fundamental parameters for selecting an air compressor. Volumetric flow rate characterizes the air supply capacity, while discharge pressure determines the performance of the actuator. These two parameters are subject to a…
The air compressor’s air‑production efficiency typically declines by 1.5% to 3.5% annually, influenced by wear, fouling, and maintenance practices. This steady deterioration not only reduces output capacity but also increases specific energy consumption. Regularly implementing energy‑efficiency maintenance measures—such…
Compressed air plays three core roles in a chlor-alkali chemical plant: it supplies high‑purity instrument air to automated instrumentation; it serves as a process medium in chlorine gas treatment, material handling, and other operations; and it supports the…
