TAG: muffler Francis fan oblique flow 2GXF pressure blower test, sales positive pressure blower, you should read the manual carefully, positive pressure blower, check the wiring method and circuit diagram; fans should carefully check whether the supply voltage to meet the requirements, the power is relative or the same phase, the ability of the requirements, electrical components. If the air intake opening operation, Francis positive pressure blower, the possibility of damage to the motor is large. Fan start preferably after the fan inlet or outlet pipe valve closed, slowly open the valve operation, to achieve the required conditions, and pay attention to the operating current fans do not exceed the rated current of positive pressure blower generally refers to the escape corridor air equipment . But we do not know how positive pressure blower works. When a fire occurs, the motor will turn on the interior air, temperature sense smoke or manual fire alarm will open, positive pressure blower tower roof open automatically, for blowing pressurized air shaft, the front chamber of the stairs by positive pressure outlet will be a steady stream of air to the front chamber, the front chamber to maintain a positive pressure to ensure that smoke will not spread in the region, while giving space to escape. When the temperature is higher than 280 ° C person has no possibility of escape, the internal fuse will blow, air is automatically shut down, specializing in the production of positive pressure blower, to prevent the fire from spreading. Positive pressure blower is pointing escape corridor air supply fan. It outdoor air pressure into the interior. When the building is on fire, it will produce a lot of smoke, carbon monoxide and other toxic gases and block the line of sight, through positive pressure blower air to escape the fire stairs, indoor smoke can not reach the stairs, to create conditions for people to escape. Positive pressure blower generally installed on the building roof. Positive pressure blower for smoke control room stairs and shared the front room of smoke, mainly to ensure in case of fire, stairway and front chamber pressure is greater than the walkway and other public areas to ensure that smoke does not enter the front room and the stairwell.
