Air vent blower introduction
High pressure centrifugal fan is generally used for forging furnace and high pressure forced ventilation. It is widely used to transport air and other non spontaneous, harmless, non corrosive gases of steel materials. There is no viscous substance in the gas, the dust and hard particles are not more than 150mg/m3, and the gas temperature should not exceed 80 degrees. For the transportation of flammable and explosive gas, the impeller can be processed by aluminum alloy to prevent sparks from running. The motor is equipped with explosion-proof motor. Its performance parameters can be the same as ordinary fans. High pressure centrifugal fan can be made into two types of right rotation and left rotation. From the side of the motor, the impeller rotates clockwise and is called "right". The impeller rotates counterclockwise and is called "left". The outlet position of the fan is expressed by the angle of the outlet of the housing.
(1) impeller: front curved impeller, the highest circumference speed of impeller diffuser can not exceed 140m/s, after the impeller is formed, it is corrected by static and dynamic balance, so it runs smoothly;
(2) casing: welded with high quality steel plate as a whole;
(3) The air inlet is made into a whole, and is installed on the side of the fan, and the wearing surface parallel to the axial is a curve shape, which can make the air enter the impeller smoothly, and the loss is small.
Rotation speed: 2900rpm for 50hz
Volume flow: 1320-1500m3/h
Total pressure: 5047-4998Pa
