Huifeng 4-72 fiberglass axial fan

 　　Imitating the same type steel made fan and connecting with the features of fiberglass products, Huifeng fiberglass fan is rationally repaired without influencing its performance. Except the transmission apparatus and mount, the fan is mainly made by fiberglass, which make it steel-saving, light, vibration isolated, rapid jump-start, low noise, less mended, long life and etc.. it can be widely used for heat outputting, air condition, acid flog clarity and acid and erosive air exporting in chemical, metallurgy, spin, food, medicine, petrol industry.
Huifeng 4-72 fiberglass axial fan Performance
　　The referred flow volume, total pressure, main shaft rotation frequency, axial power and efficiency are all in the standard condition.Atmosphere D=700 mm mercury pole, temperature t=20℃, when comparative absolute humidity is φ=50% ,r=1.2kg /m3) Acceleration g=9.8m/s All of the parameters are relative. See table 1

改变比重r,转速n,时的换算式
改变转速n,大气压力p,气体温度t时的换算式

O1/O2=n1/n2
H1/H2=(n1/n2)2(r1/r2)
N1/N2=(h1/h2)3(r1/r2)n1=n2
O1/O2=n1/n2
H1/h2=(h1/h2)2(p1/P2)(273+t2/273+t1)
N1/N2=(n1/n2)3(p1/P2)(273+t2/273+t1) n1=n2

表3

In the table：O----flow volume(m3/h) N----axial power(kw) h----speed (r/m) r----specific gravity(kg/m3)
　　　Footnote “1” refers to the alerted performance parameter. Footnote “2”refers to the pro-alert performance parameter.
　　　The needed power N was given: N=9QH/102.n.hm)K　
In this formula: Q---volume(m3/h) H--- total pressure(mm mercury pole) n--- total efficiency(%) t=temperature(℃) p---atmosphere(mm mercury pole) hm---machinery efficiency ,according to table 2

　The motor power you choose should not lower than the required.
　　When choosing fans, you should notice that the fan performance parameter and the option equipments parameter mentioned in the table refer to the air transportation coefficient in the standard condition. So in the un-standard conditions, you should transform the parameters into the standard ones according to the formula of table 1.
