Fan knowledge-Fan knowledge Fan is a machine for compressing and conveying gas. From an energy point of view, it is a machine that converts the mechanical energy of a prime mover into gas energy. Fan classification and use: Turbine fans are classified according to the principle of operation-fans that compress and transport gas through rotating blades. Positive Displacement Fan—compresses and conveys gas machinery by changing the volume of the gas. Centrifugal fans are classified according to the direction of airflow movement. After the airflow enters the fan impeller, the fan is compressed by the centrifugal force.
Axial-flow fan—The airflow enters the rotating blade channel axially. Which fan is good, because the blade interacts with the gas, the gas is compressed and flows on the cylindrical surface approximately in the axial direction after being compressed. Mixed flow fan—The gas enters the rotating blades at a certain angle with the main axis, and flows approximately along the cone surface. Cross-flow fan—The gas traverses the rotating blades, and the pressure is increased by the blades. Classification according to the level of production pressure (calculated with accurate pressure) Fan-exhaust pressure is lower than 112700Pa;
Technical requirements for fire exhaust fan
Product performance requirements,
1. The motor adopts high-quality motor.
2. The fire exhaust fan should be able to run normally for a long time under the condition that the medium temperature is not higher than 85 ℃.
3. The fire exhaust fan should ensure that it can work continuously for 30min when the temperature of the conveying medium is 280 ℃, and it can continue to operate normally when the temperature of the medium is cooled to the ambient temperature
a) At the specified flow rate, the axial pressure fire smoke exhaust fan has a deviation of ± 5%.
b) At the specified flow rate, the corresponding pressure difference of the centrifugal smoke exhaust fan is ± 5%.
5. The noise limit of sound level A of fire exhaust ventilator at the given operating point in the description shall comply with the provisions of JB / T8690.
