High pressure centrifugal fan 8-099
High pressure centrifugal fan 8-099
Product details
The purpose of the fan
The 8-09 and 9-12 high-pressure centrifugal fans are specifically designed for iron smelting furnaces, and are suitable for the performance requirements of iron smelting furnace blowers with melting rates of 1, 2, 3, 5, and 7 T/h. This fan can also be used as a blower for various furnaces and forging furnaces, and is also suitable for conveying air and gases that are non corrosive, unnatural, and do not contain viscous substances. The temperature of the conveying medium shall not exceed 80 ℃, and the dust and hard fine particles contained in the medium shall not exceed 150 milligrams per cubic meter.
Type of fan
1. The 8-09 and 9-12 types of fans are both single suction, and the 8-09 type has five machine numbers: N06.8A, 7.1D, 8D, 8.5D, and 9D; The 9-12 model has six machine numbers: N06.8A, 7.1A, 7.4D, 7.7A, 8D, and 9D.
2. Both 8-09 and 9-12 types of fans can be made into two types: clockwise rotation or counterclockwise rotation. Looking from one end of the motor, if the impeller rotates clockwise, it is called a clockwise rotating fan, represented by "clockwise"; Rotate counterclockwise, known as counterclockwise rotating fan, represented by "counterclockwise".
3. The outlet position of the fan is represented by the outlet angle of the casing, and both "forward" and "reverse" fans can be made into three angles: 0 °, 90 °, and 180 °.
structure characteristics
The 8-09 and 9-12 types of fans are composed of impellers, casings, air inlets, transmission components, seals, and machine bases. For the 8-09 models N07.1, 8, and 8.5, an integral structure is used, while the 9-12 models N08 and 9, as well as the 8-09 model N09, use a partially assembled structure.
Impeller: The blade shape is designed according to the new high-efficiency forward fan theory. After the impeller is formed, it undergoes static and dynamic balance correction, ensuring smooth and reliable operation.
Shell: Welded into a snail shaped shell with ordinary steel plates as a whole.
Air inlet: Made into a convergent streamlined overall structure, fixed to the front cover plate group with bolts.
Transmission group: composed of main shaft, bearing box, coupling, etc. The spindle is made of high-quality steel. For the 8-09 type N07.1 and 8, rolling bearing grease is used for lubrication; For the 8-09 type N08.5, 9, and 9-12 type N08.9, rolling bearing lubricating oil is used for lubrication.
