Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Currently in the industrial large-scale plant in the common natural ventilation has streamlined roof natural ventilation, natural ventilation cyclone-type roof exhaust hood and a variety of roofs and so on. Standards were prepared where the 1990s had 96K105-1 ~ 3 "barrel hood and Accessories", "circle umbrella hood" and "conical hood." Many domestic production of various types of ventilation, the use of the material in accordance with the requirements of different points of stainless steel, plain carbon steel and mineral glass. Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. No power fan bearing temperature abnormally elevated main reasons can be attributed to improper installation, poor lubrication, cooling is not enough, bearing exception. Centrifugal fan blower bearings placed outside, bearing fatigue wear peeling, pits, the gap increases will cause the temperature increases, this situation can listen bearing sound and vibration measurement methods to determine. The size of the bearing internal clearance is very important, bearing internal clearance is too small or poorly designed manufacturing precision parts, will cause the fan bearing operating temperature. Is the use of natural wind turbine fan and indoor and outdoor temperature difference caused by air convection, rotation of the turbine and thus promote the use of centrifugal force and negative effects of the indoor stale hot air out. Project location without power ventilators should be installed near the roof line, positioning, waterproof substrate rests on the roof, and side edges of the substrate tilt metal plate embedded in the gap under the roof of the Rio 50 ~ 100mm (backplane follow Alice fold 10 ~ 20mm) on the pliers. Cutting the hole to bore water board as a model Axial roof fan, draw the hole contour dwt-i type axial roof fan, then complete the hole with a roof cutter cutting. And trim polished edges. With a sharp blade to cut cotton insulation shaped by the meter ws FRP Axial roof fan, after removing part of the cotton insulation, then the insulation between the steel and cotton into cotton insulation and foil. Affixed with waterproof clay, the waterproof silicone, waterproof clay paste with water at the junction Cham board and roof cover. Complete both sides of the top of the peak, labeled waterproof clay belt, and in between the plug and the color plates marked with waterproof silicone, torn cardboard top. Axial roof fan installation | Jiangxi Axial roof fan | Flextronics ventilation provided by Liaocheng Wei Chong ventilation equipment. Liaocheng Flextronics Ventilation Equipment Co. (www.lcwctf.com) (www.lcwctf.com) strong, credible, Shandong Liaocheng fan, ventilation equipment industry has accumulated a large number of loyal customers.
