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
4. At the rated speed, in the working area, the measured pressure curve of the fan and the curve given in the manual should meet the following requirements:
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.
Jin Blower Group teaches you how to choose the right fan:
The correct selection of the ventilator is an important step to ensure the normal and economical operation of the ventilation system. The selection principle of the fan: first, high applicability; second, strong reliability; third, good economy.
High applicability, which means that the use, structure, and performance parameters of the selected fan meet the conditions and requirements of the working conditions. For example, fire exhaust fans used under high temperature, high pressure, and smoke conditions have special requirements for the materials of the fans. If you do n’t have the type and number of the fan you need, you ca n’t overcharge it, you should ask the fan manufacturer to design another.
Reliability means that the design and manufacturing quality of the selected fan fully meets the relevant national technical standards, and the quality of the accessories (such as the motor (or steam turbine) and bearings) matching the fan meets the relevant national technical standards. The fan operates reliably and has a long service life.
The economy is good, which means that the fan has high efficiency, low energy consumption, low noise, and small size. Fujian Roots fan has less space, low cost, and convenient maintenance and repair.
