Titanium fan 9-19-11

FB9-19 series glass fiber reinforced plastic high pressure centrifugal fan
1, the use of FB9-19 series of glass fiber reinforced plastic centrifugal fan is mainly used for the discharge of acid, alkali, salt and other corrosive gases, and the need for high pressure places. Medium temperature is generally not more than 65 DEG C, the impurities contained in the medium size is not greater than 150mg/m3.
2, the fan is a single suction, there is no 4, 4.5, 5, 5.6, 6.3, 7.1, 8, 9, 10, 11.2, 12.5, 14 a total of 12 machine no..
The ventilator can be made into two forms: right and left. From one end of the motor face, such as the rotation of the impeller clockwise said the right cyclone, to "right" means; counterclockwise rotation of the left wing, said "left".
The outlet position of the fan is expressed as the outlet angle of the casing. "Left" and "right" can be made into 0 degrees, 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees, a total of six angles. The transmission mode of fan for the A type (No. 4 to 6.3) and D (No. 7.1 - 14) two.
3, structural characteristics
1) the impeller consists of 12 pieces of bent glass fiber reinforced plastic blades. The impeller shaft disc (buried metal sleeve), for forming glass steel molded by static and dynamic balance, so the smooth operation.
(2) the integral molding of FRP is also used. The inlet and outlet are circular flanges, which are easy to connect.
3. The air inlet is made of glass fiber reinforced plastic mould and the integral structure of the streamline shape is formed.
4) the transmission unit is composed of a main shaft, a bearing box and a coupling. Bearing box for the overall structure, the use of rolling bearings, bearing grease lubrication.
4, performance and selection
Fan performance generally refers to the performance of the gas under standard conditions. The standard state refers to the atmospheric pressure Pa=101300Pa, atmospheric temperature t=20, relative humidity of 50%, air density =1.2kg/m3.
