The shaft flow smoke design is unique, the high -temperature motor is fully closed and built, and the special motor cooling system is equipped. The CAD software multi -target optimized design of the shaft flow and mixed impeller structure is used.Send high -temperature smoke when sending ventilation and fire protection). After the electronic control box is equipped, it can be automatically controlled.It has the advantages of excellent high temperature resistance, high efficiency, small volume, simple installation (horizontal, vertical, and hanging).Essence
1. The main control parameters of smoke exhaust fan are the operating temperature, air volume, full pressure, efficiency, noise, motor power, speed and axis power.2. The smoke exhaust fan should run normally for a long time under the condition that the medium temperature is not higher than 85 ° C.3. The smoke exhaust ventilator should be guaranteed that when the temperature of the transmitted medium can work continuously for 30 minutes when the temperature is 280 ° C, it can still run normally when the medium temperature is cooled to the ambient temperature.4. Under the rated speed and in the working area, the actual pressure curve and the curve given in the instructions of the ventilator shall meet the following regulations: A) The corresponding pressure value of the axial flow smoke exhaust ventilator shall be under the prescribed traffic.The deviation is ± 5%.b) Under the prescribed flow of centrifugal fans, the corresponding pressure deviation of the corresponding pressure value is ± 5%.5. Tobacco ventilation ventilator at the given noise of the A sound level under the conditions of the working conditions in the manual shall comply with the provisions of JB/T8690-1998.6. Tobacco exhaust fan can adopt ordinary steel centrifugal ventilation or special tobacco axis streaming ventilator. The specifications of smoke exhaust fan in accordance with the provisions of the "Fire Fire Specification of High -rise Civil Building Design".H, the large air volume should not exceed 60,000m/h (referring to the large air volume of a tobacco downturn).7. The air volume of smoke exhaust fans should increase the wealth of not less than 10%to 20%according to the required air volume value.8. The wind pressure value of the smoke -proof pressure ventilator should be calculated according to the unfavorable circuit of the smoke discharge system, and the remaining voltage value of the internal smoke -proof staircase room should be 40-50Pa.The remaining voltage value of the refuge layer is 25-30Pa.9. Fire fire exhaust fan should meet the current standard JB/T10281-2001 "Technical Conditions for Fire Fighting Tobacco Ventures".10. The fan of the smoke exhaust system should be set separately, and the position of the smoke exhaust fan should be in the same or upper layer of the smoke exhaust area.
The above is the introduction of how to choose a smoke exhaust fan product. I hope the above content can be helpful to everyone. Thank you for your viewing and support. In the later period
