Electric Centrifugal Blower Air Conveyor

1. Application

 Type G***3 and Y***3 fans are mainly used in steam boiler of the thermal power plant. 
G***3 can also be used in mines for general ventilation. G***3 is ventilation fan. 
The medium is air and the max temperature must be below *0℃; 
While Y***3 is induced fan and the medium is gas or smoke and the top temperature
 can not exceed **0℃. A dust collection device should be mounted in front of the draught
 fan to reduce the dust that may enter the fan.  
 

2. Structure

(1) Impeller:

 After blades molded, the impeller passes through the dynamically and statically balanced test to make sure
the running is stable and balanced.

(2) Case:

With ordinary steel plate welded into a whole worm shell.

(3) Air inlet:

Make constriction type streamline the oveall structure, bolted on the front cover.

(4) Transmission Parts:

Include main shaft, bearing housing, belt or coupling and so on.

(5) Motor: According customers' requirments.

(6) Accessory: Adjusting door, Silencer,Absorber

3. Installing testing and operation 
 

The following points should be paid attention to durning the process of installation:

(1) Smear some graese or machine oil on some junction surfaces in order to prevent rusting, and reduce the

difficulties when moved.

(2) When fixing the scew bolts on the junction surfaces,if there are Positioning pins,fix the Positioning pins first

then the screw blots.

(3) Check the inside of the chasssis and other cases to make sure that no tools and other substances are left in it .
 

The requirements of insallation:

(1) Install the fan according to the positiong and size indicated in the fifure.Pay a special attention to the dimension

 of the gap between the inlet port and centrifugal impeller to get high efficiency.

(2) Make sure that the spidle is in horizontal position.Measure the concentricity of the spindle and motor axle.

(3) When to install the adjusting valve,do not put it reversely .Keep the inlet direction in step with the running

direction of centrifugal impellers.

(4) After the installion,move the rotor with hand or a lvver to check whether the motor is too tight or bump the

fixed part.

(5) Do not put any weight on the fan chasssis when to install the pipes and outlet of the fan.

(6) Examine thoroughtly to see whether it meets the requirements after installed,then carry on the testing.
