Liaocheng Flextronics Ventilation Equipment Co. specializes in non-powered and non-powered natural ventilation fan and so on. Roof ventilation is also called roof natural ventilation and roof natural ventilation design and works mainly around the aerodynamics of wind vector type theory "- wind without power ventilation cap brand at the time of the object, the windward side of the pressure on the leeward side and downwind to the suction side of "and expanded, combined with structural mechanics building, after numerous tests and improvements, the formation of the relatively complete product. Its performance is mainly reflected in: (1) is designed to streamline the overall arc, both to ensure the ventilation body strength, but also effectively reduces the body is exposed ventilation pressure; (2) the use of ventilators body height and arc shape formed by the large volume, improve the ability to collect and indoor air emissions; (3) Set the boost duct (also drain) gather roof wind ventilation is formed from the bottom-up pressure thrust, driving poly exhaust hot air upwards warehouse; wind (4) in any direction across the top of the ventilation suction outlet is bound to the formation of non-powered ventilation cap offer, improve the ventilation of the pulling speed. 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 bearing is placed outside the fan without power ventilation cap companies, 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. To facilitate the installation of wind turbine equipment, overhaul and maintenance, generally designed to use more bearing adapter sleeve bearings with a tapered bore of the bearing inner ring. Finally, there is the same level to try to arrange the blade finishing on the same machine with the same knife inside a fixture finished processing the back arc, in order to achieve consistency of the whole class detachment leaves the pitch blade manufacture. No power ventilation cap brand, Flextronics ventilators (certified), Shanghai No power ventilation cap from Liaocheng Flextronics ventilation equipment 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. Flextronics ventilators in leadership with the staff warmly welcome all inquiries negotiations to create Flextronics ventilation a better future.
