Fan is the hub of the auxiliary power plant, axial fans due to the high efficiency and low energy consumption and are widely used. But axial fans have failed when the plant without power fan, then you know what Axial major fault thing. The main fault 1. Motor fault roof axial fans. Such as overcurrent, Xinxiang without power fan, burn out the motor when severe. 2. The rotor failure. Such as rotor unbalance, rotor vibration, the most serious accident or even impeller coaster. 3. blade cracks or breaks. Are likely to occur in the delivery, Fan, several cases in recent years have been a number of large power plants. The oil spill station, ball-type non-power fan, adjust the hydraulic no chaos. Not only affects the fan control mechanism also threaten the safety of fans. 5. blade wear. Mainly occur in the induced draft fan. Because ESP investment opportunity mishandled or ESP failure, resulting in induced draft fan wear. This is the fault of coal-fired power plants most likely to occur in the induced draft fan. Roof axial fans are divided into several main components are a few: turbo head: the wavy circular turbine blade head design. Axis: High quality stainless steel bottom bracket: a fully enclosed ubc bearings, lubrication-free, long life. Bracket: made of imported steel bars. Variable angle tube neck: can change depending on the roof slope angle of the neck, to stay in the rotation, greatly improving efficiency. Bottom: a metal forming machine waterproof board fire cabinet exhaust flow is based on the principles of the natural environment of the local pressure difference and gas generated by air flowing one way, without power fan specifications, so no power-driven, cost savings and Energy. Outdoor when no wind, rely on a stable temperature difference between indoor and outdoor air exchange flow is achieved. When a large outdoor natural wind velocity, time, will be able to rely on outside pressure to ensure the effective air exchange. Respiratory window or outside the window with building the perfect combination, do not affect the overall appearance. Fire cabinet ventilation exhaust fan in the same area which ventilation effect depends on the following factors: first, the size of indoor and outdoor temperature. To promote the flow of gas to drive air pressure flow. Second, natural wind outside the room size. Resulting in a large indoor and outdoor pressure differences, so that the air flow. Third, the impact of high and low temperatures also contributed to the air flow and causes exchange.
