FAQ

How to judge the fan left and right rotation?
Fan related to the system of energy transmission and distribution, building energy is a very critical part
What is the principle of explosion-proof fan?
Applicable and transport flammable and explosive non-corrosive gases, the ambient temperature shall not exceed 60 ℃, widely used in general factories, warehouses, offices, residential ventilation or strong heating
What is the difference between an axial fan and a centrifugal fan?
The former often installed in the air conditioning unit into, exit, boiler drum, induced draft fan, and so on. The latter is often installed in the duct, or the duct outlet front.
How to reduce fan noise?
3) centrifugal outlet due to the presence of the volute or the presence of the fan-shaped fan rear guide leaves produced by the presence of interference noise, discrete noise with discrete spectral characteristics, the fundamental frequency (i = 1 corresponding to the frequency) the strongest noise , Higher harmonics are decreasing.
What is the critical speed of the fan?
More than this speed after the amplitude increases with the speed gradually reduced, and stable in a certain range, the rotor maximum amplitude of the rotor speed is called the critical speed
380V axial fan has five lines how to take?
Forced wiring easy to burst switch. The operator is also unsafe.
Why the blower suddenly does not turn?
Check the above are normal circumstances, you can ask the relevant management personnel, the factory there is a phenomenon in the power flash.
What is the role of the fan?
Grain drying and selection; wind tunnel and hovercraft inflatable and propulsion, etc. The working principle of the fan and turbine compressor is basically the same,
