The outer rotor centrifugal air conditioning wind machines A large air volume, low noise, compact structure, strong and durable, good appearance, easy installation and use, etc. Widely used in all kinds of air conditioning unit of the fan fan, air curtain, changes in temperature, etc. Can also be used for industrial and mining enterprises, public indoor and ventilated take a breath. Its transmission medium is air and other harmless to the human body is not spontaneous combustion gas, gas inside there is no particulate matter, dust content is not more than 150 mg/m after.

 

Outer rotor air conditioning fan maintenance system

 

1. The outer rotor air conditioning fan must be used specialist personnel maintenance.

 

2. The outer rotor air conditioning fan is not allowed to run in spite of illness.

 

3. Regularly remove outer rotor air conditioning fan inside the dust, especially on the impeller of impurities such as dust, dirt, in order to prevent corrosion and imbalances.

 

4. The outer rotor air conditioning fan power maintenance must emphasize first stop.

 

5. In the subject matter of the thermometer and oil sensitivity check regularly.

 

6. In addition to the lubricating oil should be replaced every time after repairing, normally 3 to 6 months to replace oil at a time.

 

The main fault and the reasons of the outer rotor air conditioning fan

 

1. The bearing box violent vibration

 

(1) outer rotor different heart air conditioning fan shaft and motor shaft, shaft coupling loaded askew

 

(2) the casing or inlet and impeller friction

 

(3) the basis of the stiffness is not strong

 

(4) impeller rivets loose or deformation of the impeller

 

(5) loose impeller shaft disk and shaft, or loose coupling bolts

 

6 casing and support, bearing housing and bracket, such as the bearing box cover to the connecting bolt is loose

 

All landowners outer rotor air conditioning fan in and out of the bad gas pipe installation

 

Today the rotor imbalance, exterior rotor air conditioning fan blade abrasion

 

2. The bearing temperature rise too high

 

(1) bearing box violent vibration

 

(2) the lubricating oil quality is not bright, metamorphism, have too much dust, sand, dirt and other impurities

 

(3) bearing box cover, a connecting bolt force is too large or too small

 

(4) axis and skew rolling bearing installation, before and after the two different bearings

 

5. Rolling bearing damage

 

3. The electrode current is too large or too high temperature

 

(1) inlet pipe gate or when driving throttle valve was not locked

 

(2) flow more than a specified value

 

(3) outer rotor air conditioning fan conveying gas density is too large, or a viscous material

 

(4) the motor input voltage is too low or power single-phase power

 

(5) shaft coupling is not straight, too tight or uneven clearance aprons
