How to let the user who buy exhaust fan motor be able to achieve better ventilation ventilation and cooling?
1.For the ventilation system with the requirement of noise elimination, the axial fan with high efficiency and low circumferential speed of impeller should be selected first and made to work at high point, and corresponding measures of noise elimination and vibration reduction should be taken according to the propagation mode of noise and vibration produced by the ventilation system. Axial Fan and motor vibration reduction measures, generally can use vibration reduction foundation, such as spring shock absorber or rubber shock absorber.
2. when the Centrifugal Axial Fan is selected, when the motor power is less than or equal to 75KW, the valve can not be installed only for starting. When high temperature flue gas or air is discharged and centrifugal boiler induced draft fan is selected, the valve should be set up to prevent overload caused by cold operation.
3 .according to the axial flow fan conveying gas physical, chemical property, choose different uses of axial flow fan. Such as the transmission of flammable gas should be chosen explosion-proof axial fan; dust or coal powder should be chosen to transport dust or coal axial fan; transmission of corrosive gas should be chosen anti-corrosion axial fan; in high-temperature occasions or transmission of high-temperature gas should be chosen high-temperature axial fan.
The article explained the definition of the fan and the calculation of the Fan Power and the fan air volume in detail, and hoped that the user can better achieve ventilation and cooling, we provide a good choice.
