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 type of mechanical fan where the air flows parallel to the axis of rotation of the blades. It is used to move large volumes of air at relatively low static pressures, typically

This article analyzes three typical fan accident cases to reveal the causes of vibration and noise hazards, and proposes prevention strategies from dynamic balancing, foundation design, and vibration/

Explosion-proof motors are the core power units for critical equipment in flammable and explosive environments. Proper selection, standardized wiring, and scientific maintenance effectively prevent sa

A centrifugal fan (often called a radial fan; in higher-pressure, lower-flow services it may also be described as a centrifugal blower) is an air-moving machine that draws air into the impeller inlet

1. Definition & BackgroundA Variable Frequency Drive (VFD) energy-saving fan integrates a frequency converter between the fan motor and power source, dynamically adjusting motor speed according to sys
