Boiler Id Fan Heavy Duty Centrifugal Fans 11kw Direct Driven Connection

Heavy Duty Industrial Boiler Blower Fan High Pressure 11kw Direct Connection

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.

Belt Drive and Coupling Drive
The fan shaft shall be treated through hardening and tempering and finish turning processes up to the hardness level of HB250-280. Its maximum load shall be 35% more than the highest fan speed. The shaft shall be supported by two bearings with L10 rating service life of over 80000 hours. It shall be sealed and can be lubricated under normal operating temperatures. The pulley shall be of cast iron type and shall be sized for a minimum of 150% of the driving power. There shall be pulley and belt guard. Flexible coupling equipped with a guard shall be used. The factor of safety of power transmission and torsion shall meet the design requirements.
Motor
The motor shall be carefully matched to the fan load. It shall be IP54 rated with class F insulation. Ball bearing that can be lubricated shall be used. The motor and drive mechanism shall be isolated from the airstream to avoid grease or dirt accumulation.
Surface Processing
The surface of the fan shall be polished to remove any protuberances, welding spatters, burrs, sharp edges, scrap iron and greasy dirt before being finished with electrostatic grey 9006 epoxy coatings. The finished gloss level shall be greater than or equal to 70%. The surface shall be a level one without sags, cracks, cockles or detachment.
Nameplate
A permanently fixed aluminum nameplate shall clearly display the fan number, product model and serial number (a unique ID for each fan) so that the parts used can be traceable by customers.
