Product Introduction:
- Widely used in factories, warehouses, offices, residential ventilation or enhance the heat dissipation. If the housing is removed, it can be used as a free fan or installed in series at intervals in a long exhaust pipe to increase the wind pressure in the pipe.
This fan has a total of 46 varieties, among which 3 leaves, 6 leaves, 8 leaves and 9 leaves have nine machine Numbers, according to the diameter of the impeller, the sequence from small to large is: №3, №3.5, №4, №5, №6, №7, №8, №9, №10.
The fan impeller consists of three parts: the impeller, the casing and the collector.
Blade wheel - composed of blade, hub, etc. The blades are formed by stamping sheet steel and welded to the outer circle of the hub according to the required installation Angle. Ratio of impeller to shell (ratio of circumference to impeller diameter) =0.3.
The blades are all punched into a similar shape. The mounting Angle of the blades is: 3 pieces are divided into 10 pieces. , 15? , 20? , 25? , 30? Five; 4, 6 and 8 tablets are divided into 15? , 20? , 25? , 30? And 35? Five. The impeller is directly installed on the motor shaft, of №3 to №8 adopt two motor speeds, №9 and №10 adopt one motor speed, the air volume range is 550~49500 meters 3//, the wind pressure range is 25~505Pa (see the performance table for details).
The casing is composed of air duct and base frame, which is divided into two kinds made of thin sheet and profile.
Air collector - the air collector is made of arc streamline and stamped right sheet to reduce the energy loss at the entrance of the flow.
The experiment and application show that the fan is reasonable in design and compact in structure. Under all kinds of specified speed, the wind pressure is stable, the operation is stable, safe and reliable, strong and durable.
Note: the gas passing through the fan shall be non-corrosive, non-spontaneous combustion and no significant dust, and its temperature shall not exceed 45℃.
BT30 type explosion-proof shaft flow fan, the impeller part is made of aluminum (except shaft disc), the power is changed to explosion-proof motor, and the explosion-proof switch or switch is away from the explosive point. Other parts and axial flow fan material is the same, it is mainly applicable to chemical, pharmaceutical, textile and other industries and the discharge of explosive, flammable, volatile gas, installation process and other processes and axial flow fan the same.
