Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Roof ventilation is divided into several main components are a few: Turbine Head: The head of wavy blade circular turbine design. Axis: high quality stainless steel bottom bracket bearings: a fully enclosed ubc bearings, lubrication-free, long life. Bracket: made of imported steel bars. Variable angle tube neck: You can change depending on the roof slope angle of the neck, to stay in the rotation, greatly improving efficiency. Bottom: a metal forming waterproof substrate 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 no power ventilators, bearing internal clearance is too small or poor design and manufacture of mechanical precision fiberglass without power ventilators, fan bearings will cause 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. No power ventilation installation project should be located in the vicinity of the ridge line, positioning, waterproof substrate rests on the roof without power ventilation centrifugal, and side edges of the substrate tilt metal plate embedded in the gap under the roof of the Rio 50 (adopted on 10 ~ 20mm off the floor while Alice on pliers) ~ 100mm. 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 without power ventilators much money, waterproof clay paste with water at the junction of the roof cover plate and the Cham. 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. 500 without power ventilation parts, Flextronics ventilators, Sichuan no power ventilation ventilation equipment from Liaocheng Flextronics Limited. Liaocheng Flextronics Ventilation Equipment Co. (www.lcwctf.com) (www.lcwctf.com) is an industry leader in Shandong Liaocheng, fans, ventilation equipment, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
