Under normal circumstances, we in high-rise buildings must be set according to the specification fire elevator, where we learned that the fire should lift the front room supply exhaust fan, also known as the elevator hall, if it is combined and stairwell, then called shared room, you know this is the front room when the fire evacuation experience provides a temporary buffer space, by the fire partially into the stairs between excessive exhaust fan evacuation, therefore, it requires this space there is a certain air of liquidity. In addition we should be most aware of is that so-called positive pressure air supply, swf Francis pressure blower, it is to use machines to the outside in the fresh air is piped into such ventilation requirements of the site, which is called The positive pressure air supply. Only after more than learn the basics, Huainan pressurized axial flow fan, we can complete the entire specification leafy pressure delivery outlet installation. 4 Category Material Category: Steel fan, FRP fan, plastic fan, PP fan, Tongcheng pressure blower, PVC fan, aluminum fan, stainless steel fan, etc. By Application: proof fans, anticorrosive fans, explosion-proof fans and other types. According to the requirements of classification: pipeline, wall, post, fixed, rain and dust formula, motors and other external. 5 uses axial fan (fixed) can be used in metallurgy, chemical industry, light industry, food, medicine and other places civil ventilation or strengthen cooling purposes. If the cabinet removed, can also be used as a free fan can also be an exhaust duct in a longer interval installed in series, to increase the pressure in the pipeline. 6 Features This series of fans has a simple structure, stable and reliable, low noise, a wide range of characteristics function selection. d. daily review of the case can drip drip glib deformities, such as drops glib dirty mobilize screws can be removed and cleaned. Atmosphere through filters examine whether the daily review of the atmosphere filters dirty. As dirty atmosphere removable filter, unscrew the butterfly screw mother, removed the lid, Lu'an low pressure blower noise Francis, and cleaned up the filter sponge. (Unloading dirt filter careful not to fall into the fan inside the lead plane) to review the operation of the fan triangle with a period of time, the triangle zone will be expanded. Then pay close attention to the generator flow nut, mobile generators, triangle back for position and then tighten the nut tight flow generator housing, and pay attention to the generator pulley breeze machine pulley to be three-dimensional in the same end face on. At the same time reviewing the two screws at the top of the pulley can loose as loose Keep live. Daily review of safety valve sensitive situation, please clean up the swap as insensitive to guarantee reliable opening and closing. Daily review of whether the spill, local and repair of ventilation, such as useless repairs please tell manufacturers. Daily clearing fan room, maintain a clean, good ventilation. From time to time to review the functioning of the turbine and generators, as found the tone, when a measure is not abnormal to timely downtime.
