A fan of excessive vibration is an important factor in the operation of hot air centrifugal fan Hao Yang maximum amount of wind is affecting the safe operation of the fan and the plant's normal production of the most common faults. Fan vibration causes a lot of Texas central air conditioning fan manufacturers, a common cause: the 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) Yang-ho spectrum maximum pressure centrifugal fans, 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. DWT series fan model structure description 1, DWT- Axial roof fan diameter since ￠ 300- ￠ 2400mm, a total of seventeen kinds of machine numbers; DWT-Ⅱ centrifugal roof fan has ￠ 300- ￠ 1000mm nine kinds of machine numbers; DWT- Centrifugal roof fan diameter since ￠ 280- ￠ 800mm, a total of ten machine number; DWT-Ⅳ non-motor turbine exhaust fan 14 ", 20" and 27 "three machine number, and can also provide a number of other machines based on user needs ; 2, various types of fans can see the assembly diagram structure, which consists of the impeller, hairdryer, hood, transmission parts, loose-leaf damper, safety nets and other components; 3, the fan drive form: DWT-I type fan ￠ ≤2200mm adoption Direct drive motor, such as a user need to use a belt drive, the company is also required to produce according to applications, ￠ ≤2200mm form above using a belt drive, gear reducer can also be used in the form of fan, loose-leaf damper gravity, electric and manual three; DWT-Ⅱ, DWT-Ⅲ type roof fan, using direct-drive motor; 4, aluminum roof fan used widely, so the company needs to use a variety of different technical parameters according to user requirements. conduct research and development to improve the structure and shape; 5, the pressure is higher than the supply and exhaust fans should be used more than 600P centrifugal fan; pressure should be used in 400P-600P Francis fan; pressure is lower than 400P following axial flow ventilation should be used . strong natural wind machine outside or indoor and outdoor temperature difference is large, can be used without a motor turbine exhaust fan; Francis fan impeller motor 380V | Yangquan fans | Hao Yang air conditioning equipment provided by the Texas Air Conditioning Equipment Co., Texas Hao Yang Hao Yang air conditioning.
