Optional exhaust tips wind chassis which exhaust duct chassis varieties, specifications, wide wind, air pressure select areas. So how decisive exhaust wind chassis is reliable, sales of wind chassis, how it is to buy it? First, check the exhaust wind chassis police modulating valve opening and closing the initiative is not a rigid solid, sharp, wind chassis price, closing viewpoint symbol understand. Secondly, the police at the check manually turn lights and voltage, current meter is not working properly, the various components of fire smoke things are no different from the sound of wind chassis, air box manufacturers, three to the current value is not balanced. Then all the police check point the remote control inside each element is not normal. Three times to check off on the remote observation points are not exactly secure. Try something two hours to observe the motor bearing temperature, motor temperature is normal, sure fire thing normal exhaust wind chassis. Other fire smoke wind chassis selection, while a point necessary to introduce introduction. Its smoke pressurization fan pressure value shall be the most unfavorable loop exhaust system held accounting, and to ensure that the value of residual pressure in the stairwell between 40 ~ 50Pa. In addition, it is necessary too small, residual pressure values ??of the front room fire smoke wind chassis, shared room, fire elevator room, refuge floors and other interior 25 ~ 30Pa. Want to buy a bed of roses wind chassis should pay attention to what the problem? I believe that every wind chassis users want to buy their desirable and superior quality products, what tips? In fact, for any products, we want to buy high-quality products has its way, the user as long as the intention to acquire the relevant knowledge and understanding of the relevant characteristics of the product is important, for the wind chassis, in fact, is almost the same, users need to know in addition to to wind chassis-related parameters such as fan efficiency, noise, electrical power, wind, etc., but also according to their needs to consider all aspects of the problem in order to buy their own satisfaction, the wind chassis, specific precautions, please read : When the wind chassis selection, should take into account the loss of the piping system leakage, calculation errors, and negative deviations fan actual wind, air pressure, the general air volume of 1.05 to 1.1, pressure safety factor of 1.10 to 1.15. But do not use too large to prevent wind chassis long run in a low efficiency area. Note the pipe network resistance characteristic matching relationship with wind chassis characteristics. For the stable operation of wind chassis, should make wind chassis work near its maximum efficiency point, the wind chassis operating point performance curve to the right of the peak point of the total pressure.
