Y5-47 Y5-48 boiler centrifugal induced draft fan Application
Y5-47II' boiler centrifugal induced draft fan is suitable for 02-20t/h boilers that burn various coals and are equipped with smoke and dust removal devices. It can be used wherever the intake conditions are equivalent and the performance is compatible. But the maximum temperature shall not exceed 250℃;
Type
(1) The induced draft fan is made of single suction, and there are eleven types of machine numbers No. 3.15, 4, 5, 6, 7, 8.9, 10, 11, 12, 12.4.
(2) The induced draft fan can be made into two forms of left rotation or right rotation. Look at the fan from one end of the transmission group. If the blade turns clockwise, it is called right rotation, which is represented by "right". Rotating counterclockwise is called left rotation and is represented by "left".
(3) The position of the air outlet of the fan is expressed by the angle of the air outlet of the casing. "Left" and "Right" are made into three angles of 0°, 90° and 180°.
(4) The transmission mode of the fan is C-type and D-type, and the motor and the fan are connected by belt wheel transmission and elastic coupling direct transmission.
Features
The Y5-47II fan is an improved product based on the original Y5-47 fan. The full pressure internal efficiency of the fan at the best operating point is 85.6%, and the noise index (A sound level) is 12.5dB.
The Y5-47II fan is compared with the original Y5-47 fan. Due to a series of improvements, the noise value has been significantly reduced. In order to better meet the requirements of boiler matching, a new No.3.15C (with 0.2-0.5 t/h boiler)! 4D (with 0.7-1t/h boiler)! 5D (2t/h boiler)! 6D (with 4t/h boiler)! 7C (with 4t/h, 6t/h boiler)! 10D (with 6t/h boiler)! There are 7 types of 11D (with 10t/h boiler).
In the current industrial boiler series, there are many models, the quality of the coal used is very high, the resistance of the dust collector and the installation pipeline is different, the air volume and air pressure of the required induced draft fan are quite different. In order to apply the above situation, consider the fan It is economical and stable and reliable in operation. The fan adopts D-type and C-type transmission modes (ie coupling and V-belt transmission), among which 0.7-20t/h boilers are matched with D-type driven induced draft fans. , 0.2～10t/h boilers are matched with C-type driven induced draft fans. For V-belt conveyor units, the main shaft speed can be changed according to the actual situation to obtain a more ideal air volume and air pressure.
Structure
The fan is mainly composed of impeller, casing, air inlet, transmission group and regulating door;
(1) The impeller has 12 backward-inclined flat blades made of Q345 (16Mn), which are welded between the arc-conical wheel cover and the flat-plate wheel, and have undergone balance correction. Therefore, it runs smoothly, has high strength and wear resistance, and has a long service life.
(2) The casing is welded with steel plates to form a volute casing, which can be turned from “left” to “right” above No. 8 for general use.
(3) The main shaft of the transmission group is made of high-quality steel and adopts ball bearings (No. 3.15-7 adopts low-noise type bearings), two side-by-side bearing seats, use No. 2 calcium-sodium-based grease and fan blade self-cooling, structure simple.
(4) The air inlet is a converging and diverging air inlet, which is made into an integral structure and fixed at the entrance of the casing with bolts.
Utilization of fan
Operation is permitted only when the fan is in perfectly normal condition.
It is required to check each part of the fan for normality in case of startup of the fan upon maintenance.
The fan shall be cleaned regularly and the dust, dirt and other impurities inside conveying pipeline shall be removed at regular interval to prevent rust.
It is not allowable to repair the fan when it is in operation.
A throttling device may be used for adjustment in case of excessive flow which not in compliance with operating requirements or smaller flow required in a short time.
The fan shall be immediately stopped for inspection in case of abnormality during its startup, shutdown or operation.

Y5-47 Y5-48 boiler centrifugal induced draft fan Application
Y5-47II' boiler centrifugal induced draft fan is suitable for 02-20t/h boilers that burn various coals and are equipped with smoke and dust removal devices. It can be used wherever the intake conditions are equivalent and the performance is compatible. But the maximum temperature shall not exceed 250℃;
Type
(1) The induced draft fan is made of single suction, and there are eleven types of machine numbers No. 3.15, 4, 5, 6, 7, 8.9, 10, 11, 12, 12.4.
(2) The induced draft fan can be made into two forms of left rotation or right rotation. Look at the fan from one end of the transmission group. If the blade turns clockwise, it is called right rotation, which is represented by "right". Rotating counterclockwise is called left rotation and is represented by "left".
(3) The position of the air outlet of the fan is expressed by the angle of the air outlet of the casing. "Left" and "Right" are made into three angles of 0°, 90° and 180°.
(4) The transmission mode of the fan is C-type and D-type, and the motor and the fan are connected by belt wheel transmission and elastic coupling direct transmission.
Features
The Y5-47II fan is an improved product based on the original Y5-47 fan. The full pressure internal efficiency of the fan at the best operating point is 85.6%, and the noise index (A sound level) is 12.5dB.
The Y5-47II fan is compared with the original Y5-47 fan. Due to a series of improvements, the noise value has been significantly reduced. In order to better meet the requirements of boiler matching, a new No.3.15C (with 0.2-0.5 t/h boiler)! 4D (with 0.7-1t/h boiler)! 5D (2t/h boiler)! 6D (with 4t/h boiler)! 7C (with 4t/h, 6t/h boiler)! 10D (with 6t/h boiler)! There are 7 types of 11D (with 10t/h boiler).
In the current industrial boiler series, there are many models, the quality of the coal used is very high, the resistance of the dust collector and the installation pipeline is different, the air volume and air pressure of the required induced draft fan are quite different. In order to apply the above situation, consider the fan It is economical and stable and reliable in operation. The fan adopts D-type and C-type transmission modes (ie coupling and V-belt transmission), among which 0.7-20t/h boilers are matched with D-type driven induced draft fans. , 0.2～10t/h boilers are matched with C-type driven induced draft fans. For V-belt conveyor units, the main shaft speed can be changed according to the actual situation to obtain a more ideal air volume and air pressure.
Structure
The fan is mainly composed of impeller, casing, air inlet, transmission group and regulating door;
(1) The impeller has 12 backward-inclined flat blades made of Q345 (16Mn), which are welded between the arc-conical wheel cover and the flat-plate wheel, and have undergone balance correction. Therefore, it runs smoothly, has high strength and wear resistance, and has a long service life.
(2) The casing is welded with steel plates to form a volute casing, which can be turned from “left” to “right” above No. 8 for general use.
(3) The main shaft of the transmission group is made of high-quality steel and adopts ball bearings (No. 3.15-7 adopts low-noise type bearings), two side-by-side bearing seats, use No. 2 calcium-sodium-based grease and fan blade self-cooling, structure simple.
(4) The air inlet is a converging and diverging air inlet, which is made into an integral structure and fixed at the entrance of the casing with bolts.
Utilization of fan
Operation is permitted only when the fan is in perfectly normal condition.
It is required to check each part of the fan for normality in case of startup of the fan upon maintenance.
The fan shall be cleaned regularly and the dust, dirt and other impurities inside conveying pipeline shall be removed at regular interval to prevent rust.
It is not allowable to repair the fan when it is in operation.
A throttling device may be used for adjustment in case of excessive flow which not in compliance with operating requirements or smaller flow required in a short time.
The fan shall be immediately stopped for inspection in case of abnormality during its startup, shutdown or operation.
