Explain the difference; in addition to mixed flow (Francis) fans, axial fans high pressure coefficient ratio, flow coefficient than the centrifugal fan. To fill the gaps between axial fans and centrifugal fans of. Along with easy installation features. Francis (or axial-flow impulse) fan combines axial and centrifugal fans feature, although it looks more like a traditional axial fan. The curved plate-shaped blades welded to the conical steel hub. By changing the angle of the blade inlet in the housing upstream of the impeller to change the flow. Cabinet can have open inlet, but more common situation is flame-proof axial fan, it has the shape of a right angle bend, so that the motor can be placed outside of the pipe. Excretion slow expansion shell roof axial fan to slow down the air or gas flow and convert kinetic energy into useful static pressure. 1. Axial fan model 200FZY4-D: 200 is the fan type axial fans, YZFZ the F- fan, Z- axial fan, Y- cylindrical. Performance parameters No. 4- motor is, we often say that a 4-pole motor. 2, 3 # 4 # is the axial fan unit number, representing the impeller diameter is 300MM, 400MM corrosion axial fan, NO.3.55 is T35-11-3.55 number, your technical parameters are in line with the requirements of this motor speed is 2900R / MIN. 3, YSF-5014-type axial fan, YSF-5632-type axial fan inside the Y, S, F, 5014. The above is a brief overview of axial fan model and its implications, hoping to be helpful. Roof axial fans, axial fans Langfang City, Chen Yu-conditioning services provided by Wu Cheng Chen Yu Air Conditioning Equipment Co.. Wu Cheng Chen Yu Air Conditioning Equipment Co., Ltd.
