           High capacity blower fan for Industrial boiler forced draught
1. Application
Type ***9 & ***6 centrifugal blower is usually used in furnace and forced ventilation of high pressure. They can also be used to transfer powder, air and gas. The medium should be non-hypergolic, non-sticky and not corrosive to iron and steel .  The temperature of medium does not exceed *0°C and the dust density can not exceed **0mg/m³.

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.
