Liaocheng Flextronics ventilation equipment specializing in the production and operation without power fan and non-powered natural ventilation and so on. Ventilation is a selection method, the number of installations of ventilation volume * B = A building number ACH / C single ventilator ventilation capacity A, building volume = building length * width * height buildings building B, ventilation frequency: according to the building use function, press table selection of two, noted: The above selection criteria are based on the average plant ventilation skylights set national statistics, under specific conditions and the environment by the manufacturers of professional choose the number of authorized personnel. Liaocheng Flextronics ventilation equipment specializing in the production and operation without power fan and non-powered natural ventilation and so on. No power wind balls distribution cabinet should be paired balls wind turbine without power distribution control box must match the corresponding fan (of power, voltage, pneumatic control forms, etc.). Wiring by a qualified electrician wire the fan ventilation skylight roof, wiring must be correct and reliable, especially numbered wiring consistent numbering fan electrical control box at the terminal on the fan housing should be reliable grounding must be reliable, can not be replaced with access to zero grounded. It must have safety devices to prevent accidents by professionals familiar with the relevant safety requirements of the installation and wiring installed unpowered typhoon. Importers fan duct connection with a separate support, do not allow the pipeline overlap weight to the fan parts; turbine installation should pay attention to the horizontal position of the fan ventilation skylights, coupled to the turbine and foundation combined surface and the wind pipe should adjust it so natural fit, not be forced to join. No wind power installation of rectangular ventilation skylights ball, hand or lever toggle impeller, check for tight or collision, the availability interfere with the rotation of items, with no anomalies, commissioning can be carried out, the fan drive device the exposed part should guard (user) as the fan inlet is not connected to the pipeline, but also need to purchase fencing or other mounting device (user-supplied). Liaocheng Flextronics ventilation equipment specializing in the production and operation without power fan and non-powered natural ventilation and so on. A roof ventilation equipment for industrial plants axial fan 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, can effectively cost and energy savings. 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. Natural ventilation skylights, Heilongjiang ventilation skylights, Flextronics ventilation provided by the Liaocheng Wei Chong ventilation equipment. Natural ventilation skylights, Heilongjiang ventilation skylights, ventilation Flextronics Flextronics is Liaocheng ventilation Limited (www.lcwctf.com) (www.lcwctf.com) this year introduced a new upgrade, the above picture is for reference only, please dial this Tel pages or pictures on obtain the latest information, contact: Du Jingli.
