Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Axial fans a special energy efficiency, curved blades is the result of the best results of scientific computing without power ventilators, to ensure strict working condition will never let rainwater intrusion. High exhaust efficiency, as long as not less than 0.2 meters in the breeze or indoor and outdoor temperature difference exceeds 0.5 ℃ without power ventilators price, you can light and efficiently. 2, the central axis has a fine level, so that the high-speed operation of the turbine blades never deformation, which greatly improves the fan's life. 3, variable angle neck design allows the fan installed in 0-22.5 degrees bevel under arbitrary. 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 ventilation without power accessories, 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 the hole waterproof substrate as a model, draw the outline of the hole, and then complete the hole in the roof cutter cutting. And trim polished edges. With a sharp blade to cut cotton insulation shaped by the meter, after removing part of the insulation cotton, cotton insulation and then aluminum foil insulation between the steel and cotton stuffed. 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 crest without power ventilation manufacturers, affixed with waterproof clay, and between the plug and the color plates marked with waterproof silicone, torn cardboard top. No power ventilation Accessories | Guangxi without power ventilators | ventilators from Liaocheng Flextronics Flextronics ventilation equipment Limited. 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. The company better work attitude and constantly improving innovative ideas will lead Flextronics ventilators and you hand into the brilliant, for a better future!
