Product Description
Product description:
The main control parameters of the smoke exhaust fan are working temperature, air volume, full pressure, efficiency, noise, motor power, speed and shaft power.
2.
The smoke exhaust fan should be able to operate normally for a long time under the condition that the medium temperature is not higher than 85°C.
3.
The smoke exhaust fan should ensure that it can work continuously for 30min when the temperature of the conveying medium is 280 °C, and can still operate continuously and 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 instruction manual shall meet the following requirements:
5.
The deviation of the pressure value of the axial flow smoke exhaust fan under the specified flow rate is ±5%.
6.
The deviation of the pressure value of the centrifugal smoke exhaust fan under the specified flow rate is ±5%.
7.
The noise limit of the specific A sound level at the specified working point in the instruction manual shall comply with the provisions of JB/T8690-1998.
8.
The smoke exhaust fan can be an ordinary steel centrifugal fan or a special smoke exhaust axial fan. The specifications of the smoke exhaust fan shall be in accordance with the provisions of the Code for Fire Protection Design of High-rise Civil Buildings. The minimum air volume of the smoke exhaust fan is 7200m/h, and the maximum air volume should not exceed 60000m/h (refers to the maximum air volume of a smoke exhaust zone).
9.
The air volume of the exhaust fan should be increased by no less than 10%~20% according to the required air volume value.
10.
The air pressure value of the smoke-proof pressurized ventilator should be calculated according to the most unfavorable loop of the smoke exhaust system, and the residual pressure value in the smoke-proof stairwell should be guaranteed to be 40~50Pa. The residual pressure value of the front room, the shared front room, the front room of the fire el
