Positive pressure air supply units, positive pressure blower, Francis fan

 Positive pressure blower is pointing escape corridor air blower. 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 line of sight, through positive pressure blower air to escape the fire stairs, indoor smoke can not reach the stairs, to create the conditions for people to escape. Positive pressure blower usually installed on top of buildings, and the layers of the positive pressure valve linkage. Initial fire damper is open, positive pressure blower starts, so the stairwell, elevator hall in positive pressure (air condition). Ventilation area to see about constant air volume range, according to the calculation of wind damage piping, finalized model. The basic structure of the type of inlet and outlet on the same axis (ie axial flow structure), round shell as cones, leaves of varying width along the flow direction was like. There are straight cylindrical shape, a drum-shaped and curved plus three types of mufflers and other imports. According to the meridional flow positive acceleration principle roof blower fan has the dual characteristics of centrifugal and axial, that both have a large high pressure flow, and has a high efficiency, low noise, high efficiency and wide area and so on. Compact, light weight, easy installation, small footprint. Installation and Use: horizontal, vertical and ceiling can be installed. Ventilation, air and pipeline pressure can be used. Positive pressure blower routine maintenance can extend the life of any kind of good products are required to perform routine maintenance, of course, the positive pressure blower is not the exception. For positive pressure blower for positive pressure blower swf, routine maintenance can be a good guarantee positive results as well as the use of blower life, this is no doubt gxf positive pressure blower, so Conversely, routine maintenance of good positive pressure blower, you can extend the life of positive pressure blower. When the daily maintenance of positive pressure blower, pay attention to when we want to maintain the level of the installation position of the fan, the fan and the foundation of the joint surface and the duct joints, etc., should be adjusted so that there is not a natural fit forcibly join, do not allow the Pipeline weight added to the fan parts; each part to deal with when installing conduct a comprehensive inspection, parts are complete, the components are tightened connection; if it is used in the open-air environment, we must pay attention to the measures taken by rain; if in operation found to have severe vibration impact and other anomalies, should immediately stop checks, to identify problems and timely treatment; regularly clear the internal positive pressure blower fouling, dirt and other impurities, and to prevent corrosion. Now, with the continuous development of the fan industry, positive pressure blower demand is also increasing, so how can we do to alleviate this problem, in addition to the major manufacturers to increase positive pressure blower production, is to do positive blower routine maintenance work, extend the life of positive pressure blower, the only way to relieve positive pressure blower demand rising trend.
