Liaocheng Flextronics ventilation equipment specializing in the production and operation without power fan and non-powered natural ventilation and so on. No power ventilation air using the principle of natural convection, becomes in any direction parallel to the flow rate, and the vertical air flow conversion. With the use of the chimney effect itself, buildings and equipment to achieve an internal and external ventilation equipment. No power ventilation applications: large factories, ventilation installation, warehouses, stadiums, pet farm Ribbon, foreign ventilation, high-rise buildings, residential and other ventilation. No power ventilation product features a zero cost of running 24 hours without personnel to operate, lightweight, environmentally friendly, no noise, long life, easy installation and fast, wide applicability, distinctive round shape (Taiji principles to resolve the horizontal pushing) and a support structure, in order to ensure the turbine can withstand typhoons. It uses a unique variable angular diameter, as long as the pressure plate from 0 to light a variety of industrial plants steel roof angle, can be directly installed concrete roof slope can also be installed together with other accessories. An axial fan roof ventilation flow is based on the principles of the natural environment of the local pressure difference and gas generated by the flow of air, the roof is not required powered axial fans, power ventilation, can effectively save costs and energy. When the outdoor no wind, you can rely on a stable temperature difference between indoor and outdoor air exchange flow is achieved. When a large outdoor natural wind velocity, time, roof axial fans will be able to rely on outside pressure to ensure the effective air exchange. Under the same ventilation area ventilation effect depends on the following factors: 1. the size of indoor and outdoor temperature. To promote the flow of gas to drive air pressure flow. 2, outside the room size natural wind. Resulting in a large indoor and outdoor pressure differences, so that the air flow. 3, the impact of high and low temperatures also contributed to air flow and exchange of reasons. Liaocheng Flextronics ventilation equipment specializing in the production and operation without power fan and non-powered natural ventilation and so on. No power ventilation system on the roof of the plant, can achieve very good ventilation effect. Because often due to the operation of the machine tool to produce heat and smoke pollution in the factory, according to the "thermal expansion and contraction," the principle of hot air expands, so the number of molecules in a given volume of air is reduced, relative geothermal air density will be smaller than the cold air , ventilation, hot air that is lighter than cold air, so the indoor hot air to rise, cool air to fall, the indoor heat or smoke pollution can accumulate in the vicinity of the roof, so the indoor temperature is high, the pressure. Then as long as the rotation of the turbine on the roof with no power fan, heat or indoor smoke pollution will be by the blade clearance for diversion method works spin out outdoors, when the heat is withdrawn without power ventilators interior will produce low pressure, while the outdoor air lower than the high pressure, the air flows into the interior, filling the extracted heat space, and then to adjust the temperature, to the decontamination of smoke effects, indoor air becomes clean and cool. Factory explosion-proof axial fans, Wall-type exhaust fan, HTF exhaust fan, Francis fan, EX explosion-proof axial fans, multi-leaf dampers, roof fans, valves, smoke damper, no power ventilators, exhaust fans , fan, glass steel products, glass steel products, CDZ ultra low noise axial fans, Grille, coal mine explosion-proof axial fans, with elbow fans, explosion-proof fans, FT35-11 FRP axial fan, single Grille, HL3-2A Francis fan, DZ low-noise axial fan ventilation equipment Liaocheng Flextronics Ltd. specializes in non-powered and non-powered natural ventilation fan and so on. "Roof natural ventilation Selection and Installation" GB Atlas 1 Scope: This portfolio is suitable for large industrial plants and civil tall space economically rational use of natural ventilation place, and should give full consideration to the local outdoor weather conditions. 2, natural ventilation types: natural ventilation include streamlined roof and roof natural ventilation cyclone type two kinds. It does not include all types of roof exhaust hood. Streamlined roof natural ventilation is installed on the roof, the use of heat and pressure to achieve the formation of indoor and outdoor temperature indoor air replacement device. In between the boiler, turbine and so have a lot of heat between the workshop used this device. Ventilators, Flextronics ventilation, window ventilation consists of Liaocheng Flextronics ventilation equipment provided.
