Pulverized Coal Centrifugal Blower Fan Wear-Resistant Blade Explosion-Proof

The Model 9-19 and 9-26 high-pressure centrifugal fan is extensively applied to transmit materials. The transmission medium is air or other non-flammable gases, which are harmless to human. The medium does not contain any adhesive materials. The gas temperature is ≤80℃,and the dust and particle volume are ≤150mg/m3. It is generally suitable for enforced high pressure ventilation in such
industries as forging and smelting, glass, pottery, electroplating, battery and wireless sectors, etc. It is also used to deliver grain, fodder, ore powder, plastics, etc. in the processing industries. It is also suitable for the combined use with carton machinery and tempered glass equipment.

1. 9-19 type coal powder centrifugal fan is designed according to the performance required of the coal-fired combustion system of the thermal power station boiler. It is used to blow coal powder to the boiler. The coal powder cannot pass directly through the impeller, otherwise the impeller is easily worn. The inside of the volute is lined with a guard plate for replacement after wear. There is lubricating oil in the bearing housing for heat dissipation of the bearing and a cooling water pipe to cool the lubricating oil.

2. 9-19 type pulverized coal centrifugal fan performance parameter table The parameters provided in the performance table, its calibration conditions: atmospheric pressure is 101325Pa, intake air temperature is 70 °C, medium gas (air) density is 1.02kg/m3.

Advanced Process
All steel laser cut blades are welded and positioned accurately. The overall strength of the blades are designed and welded to withstand long hours high speed operation.

High Performance Curve

The wheel has a stable, smooth air performance curve which can efficiently avoid performance drop caused by the deviation of the working point.

High Balancing Level

Each wheel is subjected to dynamic balance test. The balancing level is kept at G4.0 (Typical products are balanced to G6.3 only). Durability, stability and quietness are guaranteed.
