Information
The cross flow fan is a small high pressure centrifugal fan with a forward multi-blade impeller. The gas enters the impeller from one side of the outer edge of the rotor and then exits the interior of the impeller from the other side. The gas is subjected to the force of the blade twice in the impeller. Under the same performance conditions, its size is small and the rotation speed is low. Cross flow fans have higher efficiency than other types of low speed fans. Its axial width can be arbitrarily chosen without affecting the flow state of the gas, and the gas remains evenly distributed throughout the width of the rotor. Its outlet section is narrow and long and is suitable for installation in a variety of flat equipment for cooling or ventilation.
 
Introduction
 
The cross flow fan is a small high pressure centrifugal fan with a forward multi-blade impeller. The gas enters the impeller from one side of the outer edge of the rotor and then exits the interior of the impeller from the other side. The gas is subjected to the force of the blade twice in the impeller. It has a small size and low speed under the same performance conditions.
 
Characteristics
 
Cross flow fans have higher efficiency than other types of low speed fans. Its axial width can be arbitrarily chosen without affecting the flow state of the gas, and the gas remains evenly distributed throughout the width of the rotor. Its outlet section is narrow and long and is suitable for installation in a variety of flat equipment for cooling or ventilation.
 
performance
 
The performance parameters of the ventilator mainly include flow, pressure, power, efficiency and speed. In addition, the size of noise and vibration is also the main technical indicator of the ventilator. The flow rate is also called the air volume, expressed in terms of the volume of gas flowing through the fan per unit time; the pressure is also called the wind pressure, which refers to the pressure rise value of the gas in the fan, and there are static pressure, dynamic pressure and full pressure; the power is Refers to the input power of the fan, ie the shaft power. The ratio of the effective power of the ventilator to the shaft power is called efficiency. The ventilator has a full pressure efficiency of up to 90%.
 
future development
 
The future development of the ventilator will further improve the aerodynamic efficiency, device efficiency and efficiency of the ventilator to reduce power consumption; replace the large centrifugal fan with an axial flow fan with adjustable blade; reduce the noise of the ventilator; Wear resistance of the impeller and casing of the dust exhaust fan; realize variable speed regulation and automatic adjustment.
