Octagonal fiberglass roof fan using characteristic octagonal fiberglass roof fan of using aluminum roof fan is characterized by advanced roof ventilation equipment. Ventilation is mainly applied to hotels, restaurants, theaters, office buildings, laboratories, factories, residential and other buildings. Fans of the series with a beautiful shape, knot maple compact, high strength, light weight, small power consumption fans what? , Corrosion resistance, anti-aging, low power consumption, low noise, reliable operation, easy installation and maintenance, etc., using a venturi tube entrance test how centrifugal fan wiring, compared with similar products, efficiency increased by 30%. According to user needs my company can produce any proof roof fan big fan pressure? , Vibration performance with the same number is the same as a hot air blower operation exceeded the most common failure is an important factor affecting the safe operation of the fan and the plant's normal production. Fan vibration causes are many common causes: rotor imbalance, the system of bad, loose, Stator friction, bearing failure, rotor bending resonance, fan motor failure caused by vibration. 2. Heaters rotor imbalance causes and treatment of the rotor imbalance is the most common cause of excessive vibration fan. Simple rotor unbalance vibration characteristics Obviously, their performance: (1) approximately sinusoidal waveform; (2) the spectrum, the harmonic energy is concentrated at the fundamental frequency. Because sintering plant, pellet plant process Heaters special working environment, leading to the fan rotor imbalance factor is relatively complex. What fan air volume, Yuncheng fans, air-conditioning equipment provided by Hao Yang Hao Yang Air Conditioning Equipment Co., Texas. Air Conditioning Equipment Co., Texas Hao Yang (www.dzapjt.com) strong, credible, in Dezhou fan, ventilation equipment industry has accumulated a large number of loyal customers.
