Depending on the physical and chemical properties of the gas being transported, fans of different uses are selected. Such as the delivery of clean air, should choose a general fan; transport flammable and explosive gases, explosion-proof fan should be selected; corrosive gas transmission, corrosion-resistant fan should be used. Pipeline fan control parameters for the air volume, pressure, efficiency, noise, motor power and so on. Fu Sheng pipe fan manufacturers for your guidance, so you no longer confused!
Pipeline fan product selection points:
1, the selection of pipe fan control parameters for the air volume, total pressure, efficiency, noise, motor power and so on。
2, according to the physical, chemical properties of the gas being transported, select the fan for different purposes. Such as the delivery of clean air, should choose a general fan; transport flammable and explosive gases, explosion-proof fan should be selected; corrosive gas transmission, corrosion-resistant fan should be used.
3, Pipeline fan selection, should consider pipeline leakage, calculation error, and the fan actual wind, wind pressure negative deviation, the general air volume 1。05 ~ 1。1, the wind pressure of 1。10 ~ 1。15 safety factor。 However, it is neither too large nor too large to prevent the fan from operating in an area of low efficiency for a long time。
4, pay attention to the matching characteristics of the pipe network resistance characteristics and fan characteristics。 In order for the ventilator to operate stably, the ventilator should be operated near its maximum efficiency point。 The operating point of the ventilator is located on the right side of the full pressure peak point in the performance curve (ie, on the gales side and generally at 80% of the full pressure peak) )。
5, the ventilation system with muffler requirements, you should first select a high efficiency, low impeller circumferential speed fan, and make it work near the highest efficiency point。 Should also be based on the ventilation system noise and vibration propagation, take the appropriate noise reduction and damping measures。
6, Pipeline fan through the blade shape changes, the air flow into the fan, the existing part of the axial flow, but also produce part of the centrifugal effect, so its performance is between the axial flow fan and centrifugal fan.
7, the duct fan to provide stroke pressure and moderate air flow, which for most of the current high-rise civil buildings in the ventilation system is more appropriate.
