Y5-47 Boiler Fan
Patent No.:
Y5-47 centrifugal fan
First, the use of fans
Y5 -47 boiler centrifugal induced draft fan , is to adapt to the burning of coal and is equipped with smoke and dust removal device for industrial boilers ( one a 20 t / h ) and the joint design of the highest efficiency up to 87.4% of the total pressure of the new series boiler Fan , Where the inlet conditions can be quite the performance but also those who may choose to adapt , but the maximum temperature does not exceed 250 ℃. In the induced draft fan , dust removal device must be added in order to ensure access to the fan low dust content in flue gas , dust removal efficiency of not less than 85%.
Second, the characteristics of the fan
Current industrial boiler series are more pros and cons of burning coal and the poor, with the dust resistance varies with the required fan of wind, air pressure quite different. To meet the above situation , taking into account the economics of wind turbines , in addition to (D type ) Direct coupling transmission , but also uses triangular tape (C -type ) transmission, not only to a number of different machine speed to meet the same tonnage of boiler configuration requirements of various types of dust , reducing the fan series and machine number, but also facilitate the use of units , according to the actual situation, the main self- transformation to obtain the desired speed of an ideal wind, air pressure .
Third, Fan Type
1 , Fan made of a single inhalation , machine number has No 4,5,6,8,9,10,11,12,12.4 nine kinds .
2 , induced draft fan can be made along the rotation or reverse rotation of the two forms, from the drive unit to face fans, such as the impeller rotates clockwise as the right to the "right " means : counterclockwise rotation , called the left rotated " left ".
3 , the fan outlet to the cabinet position of the outlet angle . "Right ", "left " can be made 0 °, 90 °, 180 ° three kinds of angles.
Fourth, the main components of the structure and characteristics
Fan impeller , housing, air inlet , transmission unit and other components , and is equipped with adjustable door .
An impeller : There are 12 , the material is 16Mn backward flat blades, welded to the arc cone -shaped roulette wheel cover with the flat middle of the static and dynamic balance correction , so smooth , high strength and wear resistance , longer service life .
2 , chassis : steel plate welded into a volute casing whole. No8 more "right" , "left" turn universal .
3 , air inlet : convergence and divergence type inlet into the overall structure , bolted to the inlet side of the cabinet .
4 , transmission group : Spindle made from high quality steel, with ball bearings , two parallel bearing, bearing grease or key disulfide grease lubrication and self-cooling fan : simple structure .
5 , adjust the door : the door is adjustable fan attachment to regulate the flow of fans . Adjust the door leaf No4-9 No 8 for the disc -shaped petal-shaped above , axially mounted in front of the inlet , because the structure of the external drive , drive flexibility. Adjustment range is from 90 ° ( fully closed ) to 0 ° ( fully open ) . Adjust the position of the door pull from the air inlet direction, in the right bite tight corner . On the right-hand rotary fan pull the push from the bottom up from fully closed to fully open direction : For L-fan , pull the pull -down is made from fully closed to fully open direction .
In order to adjust the door departments work will side good lubrication, grease high temperature (260 ℃) bentonite grease , the fan operation temperature lubrication can be ensured .
