Specifications
Through the high-speed motor which drives the rotation group to drive the impeller and the rotating mechanical energy is convertPurpose:
Y5-47 type centrifugal fan with high efficiency, low noise, large air volume, and can adopt stainless steel material, have anticorrosive effect. Induced draft fan for the gasification of all kinds of coal and smoke prevention and dust control device 0.2 2 t/h industrial boiler or furnace life form a complete set of design. Conveying gas temperature shall not exceed 250 °C.
Single suction, induced draft fan is made with No. 3.15 ~ 12.5 No wait for a variety of models.
Induced draft fan is made about rotation in two forms. Face the fan from transmission group, such as the impeller rotating clockwise, known as the right to rotate the fan. As the "right"; Counterclockwise rotation, called left to rotate the fan, expressed as a "left". Fan export position to export Angle said chassis. Both "left" and "right" can be made into 0 ° and 90 °, 180 ° 270 ° from four angles.
Structure:
The fan is mainly composed of the impeller, the air inlet, chassis, transmission group, etc.
1) by 12 pieces of material for the impeller Q235A
Backward of arc blade, flat welding with arc conical wheel cover and wheel. Through dynamic and static balance correction, so the stable running.
2) the casing with ordinary steel plate welded into the volute casing as a whole.
3) inlet made sword type streamline the overall structure. Bolted side entrance to the chassis.
4) transmission part is composed of main shaft, bearing housing, belt wheel, etc, the spindle by the high quality steel, the overall structure, bearing box adopts rolling bearing, roller bearing with sodium calcium base grease lubrication.
Working principle:
Through the high-speed motor which drives the rotation group to drive the impeller and the rotating mechanical energy is converted to gas pressure and kinetic energy, and through the casing gas piped out.
Product model and the main specifications:
The fan performance generally refers to the performance of the conveying gas under normal conditions.
Standard conditions refers to the atmospheric pressure Pa = 101.3 kPa, gas t = temperature 20 °C, relative humidity, x = 50% gas density rho = 1.2 kg/m after.
When using condition does not accord with standard state, you must will use table according to the relation between the conversion performance.
