Driven by China’s “dual carbon” goals and the push for industrial green transformation, the domestic DC centrifugal fan market is experiencing explosive growth. This article analyzes the development t

In high-temperature or highly corrosive applications, fan sealing and lubrication systems face challenges such as dynamic leakage, lubricant failure, and accelerated component aging. This article syst

Noise and vibration generated during fan operation not only affect workplace comfort but can also accelerate equipment fatigue and failure. This article systematically introduces the mechanisms of aer

This article delves into the core design concepts and frequent mistakes in achieving pressure balance in ventilation duct networks. It covers resistance matching, valve configuration, CFD simulation v

1. Working PrincipleMultistage Boosting:Each impeller takes in air discharged from the previous stage, increasing pressure sequentially; the high-speed radial airflow is converted to static pressure i

Impeller material directly affects the service life and reliability of fans. This article compares the corrosion resistance, mechanical properties, and cost of common materials such as cast iron, stai

This article systematically outlines standardized methods and on-site acceptance criteria for fan performance testing, covering key indicators such as flow rate, pressure, efficiency, power, and sound

An axial flow fan is a ventilation device that uses rotating blades to propel airflow along the axis of the fan. Widely used in mines, industrial plants, tunnel exhaust, and large workshop ventilation

Deep mines face severe challenges due to high temperature and humidity from geothermal heat and machinery, along with dust and harmful gases, putting ventilation and cooling systems to the test. Tradi
