1. The main control parameters of smoke discharge are the working temperature, air volume, full pressure, efficiency, noise, motor power, speed and axis power.2. Tobacco -exhausting should be able to run normally for a long time under the condition that the medium temperature is not higher than 85 ° C.3. The tobacco discharge should be guaranteed: when the temperature of the transmitted medium can work continuously for 30 minutes when the temperature is 280 ° C, it can still run continuously and normal when the medium temperature is cooled to the ambient temperature.4. Under the rated speed, in the working area, the tangent curve given in the actual measurement pressure curve and the instruction manual shall meet the following regulations: A) Under the prescribed traffic, the corresponding pressure deviation is± 5%.b) Under the specified traffic, the corresponding pressure deviation of the corresponding pressure value is ± 5%.5.Regulations of /T8690-1998.6. Tobacco discharge can be used for ordinary steel -made centrifugation or special tobacco axis.The specifications of smoke in accordance with the provisions in the "Fire Fire Specifications of High -level Civil Architecture".The smallest air volume of smoke is 7200m/h, and the air volume should not exceed 6000m/h (referring to the air volume of a smoke excrement partition).7. The amount of smoke flow should increase according to the required air volume value of not less than 10%to 20%.8. The wind voltage value of the smoke -proof and pressure -proof and flushing should be calculated according to the most unfavorable circulation of the smoke discharge system, and the remaining voltage value of the smoke -proof staircase room should be 40-50Pa.The remaining voltage values ??of the front room, the front room, the front room of the fire elevator, and the refuge layer are 25-30Pa.9. Fire fire smoke should meet the current standard JB/T10281-2001 "Technical Conditions for Fire Fighting Tobacco".10. The smoke exhaust system should be set alone.The position of smoke should be in the same layer or upper layer of the smoke discharge area.
The above is how to choose the introduction of fire high -temperature smoke exhaust fan, I hope it will be helpful to you.If you want to know more about related information, please pay more attention to us--
