How to see the axial fan is good or bad?
Axial fans are mainly composed of fan impellers and housings. The structure is simple but the data is very high.
The Axial fans are often used in situations where the flow rate is high and the pressure is low. The axial fan is fixed and moves the air
2, axial fan, the use of a very wide range, that is, with the fan axis of the same direction of the air, such as fans, air conditioning fan is the way the fan running fan. It is called "axial flow" because the gas flows parallel to the fan shaft
And then power running to see if there is too much vibration and noise during operation, the motor's three-phase current is normal and balanced.
1, to determine whether the normal axial fan, just test the motor's three-phase DC resistance, insulation resistance, check the impeller rotation is flexible, whether there is too large radial string and axial string,
