Xiaobian to introduce today the role of Shanxi fan static pressure in the system: If you say that speed is reduced, Shanxi fan flow changed little, it should be noted that the two are not the same corresponding operating point, which is the operating point further back. Wind changed, then the dynamic pressure constant (dynamic pressure and air volume is directly related), this time, the static pressure is relatively lower, i.e., a greater decrease of said amplitude. If the fan flow Shanxi little change, the system changed little resistance this time, when substantially reduce static pressure, it is difficult to guarantee that sending such a large amount of wind. For Shanxi fan, when the fan speed is reduced, the amount of wind should be reduced, and speed is a linear relationship; the fan total pressure, dynamic pressure, static pressure is reduced, the square of the speed of a linear relationship; power and speed of three times party is linear. Fan is a prime mover of the mechanical energy is converted to transport gas, giving gas mechanical energy, which is essential for thermal power plants in Changzhi fan manufacturing plant machinery and equipment, mainly blower, induced draft fan, a fan, exhaust fan and dust seals machines, power consumption accounts for about 1.5% to 3.0% of the power plant generating capacity. In actual operation of thermal power plants, wind turbine manufacturing plant in Datong fans, especially due to the induced draft fan relatively harsh operating conditions, a high failure rate, according to the statistics, Fan average of 2 times per year failure, high efficiency motor blower annual average failure was 0.4 times jiexiu fan manufacturing plant, resulting in unplanned outages or load shedding operation. Therefore, quickly determine the cause of the failure to produce the fan running, take effective measures to solve is to protect the safe operation of power plants. Although the failure of many types of fans, the reason is very complex, but the actual operation of the plant according to the survey more fan failure are: bearing vibration, bearing temperature is high, the rotor blades jam protection device malfunction. Changzhi fan manufacturing plant, fan manufacturers, Shanxi nagorye blower provided by the Shanxi nagorye blower limited liability company. Shanxi nagorye Blower Co., Ltd.
