What are the classifications of AC Axial fans？

This AC axial fan has many different characteristics in terms of structural configuration, design method, and internal flow phenomenon, and it is not easy to grasp the fan's low-noise design and internal flow mechanism. The research on noise reduction of this kind of AC axial fans at home and abroad is mostly carried out by experimental means or some specific methods after the blade is formed, while the research on the curved and swept design of the air-conditioning fan to achieve its performance improvement is rarely reported.

Understanding of the components of the fan structure

What are the advantages of AC Axial fans?

Understanding of the components of the fan structure

1. Impeller is made by PBT UL 94V-0 reinforced plastic, frame is made by aluminum alloy.

2. The bearing type is divided into balls, oil, and hydraulic. The material is generally PBT environmental protection/fireproof material.

3. The classification of fan blades and connection structure is different, according to the size of the shaft core 3.0, the key inspection items.

4. Motor housing: material, SPCC cold rolled steel plate and electrolytic plate, SPCC white zinc and blue zinc plated specifications: 30.0*12.50*0.5

5. Rubber magnetic strip: Main ingredients: vulcanized rubber + magnetic powder. Specification: 88.0*14.10*1.90

6. Oil bearing: copper-iron alloy (copper 15-18% + the rest is iron/pure copper above 90%), connection structure: oil and hydraulic, with impregnated oil, specification: 3.000*7.01*10.00, bearing precautions.

7. Lubricant: Externally added oil GLY2100 oil and G-741 oil. 2100 oil is synthetic oil, and 741 is a fat oil.

8. Oil ring: divided into red and black, generally red is silicone and black is rubber

Specification: ID2.80*D1.0

9. Buckle ring: general material Mylar, specification: OD6.0*2.5*0.35 white

10. Ball: According to the size: 830: outer diameter 8.0* inner diameter 3.0 520: outer diameter 5.0 inner diameter 2.0 The ball has a swimming gap and needs to be preloaded.

What are the advantages of AC Axial fans?

1. The aerodynamic performance of the new AC axial fan remains basically unchanged. Under the migration, the measured noise of the AC axial fan is 0.5-1.3dB (level A sound pressure level) lower than that of the prototype wind wheel;

2. The AC axial fan reduces the lateral migration ability of the suction surface and the vortex area near Lunyi, enhances its radial migration ability, reduces the influence area of the secondary vortex in the blade channel, increases the mainstream area, and slows down the mainstream, Noise reduction;

3. The new AC axial fan basically eliminates the separation of the leading edge of the prototype fan in the middle of the wingspan.

It is the responsibility of each manufacturer to produce Ac Axial fan that meets the standards, so as to ensure the safety of the electricity supply and the healthy development of the cable market.  It conducts many tests on Ac Axial fans before they leave the factory, and the quality qualification rate is guaranteed.
