Product Description

Structural features

Air volume range:15229~810000m³/h

Wind pressure range:553~8720Pa

Driving mode: direct connection(D)

Model range: 8#~31.5#

Direction and angle: it can be made clockwise or counterclockwise. it can be made into six angles of 0 ° 45 ° 90 ° 135 ° 180 ° 270 °

Overall structure: the fan is mainly composed of impeller, casing, air inlet, regulating valve and transmission part.

Impeller: it consists of 12 blades obliquely cut by backward inclined wing, which are welded between the conical arc front disc and the flat plate rear disc. Due to the use of wing blades, the fan has high efficiency.low noise and high strength, The impeller is adjusted by static and common balance, so it runs smoothly The impellers of ventilation and induced draft fans with the same unit number have the same structure.

Casing: volute body welded with high-quality steel plate. The casing of single suction fan is made into three different forms.

Air inlet: the convergent and streamlined air inlet is made into an integral structure and fixed on the inlet side of the fan with bolts.

Applicable environment: the medium conveyed by the fan is air, and the maximum temperature shall not
exceed 80 'c,the medium conveyed by the induced draft fan is flue gas, and the maximum temperature
shall not exceed 250 ℃, A dust removal device must be installed in front of the induced draft fan to reduce the dust content of the flue gas entering the fan as much as possible, According to the use of generalpower plants, the dust removal efficiency shall not be less than 85%.

explosion proof, anti-corrosion and high temperature resistant structures can be specially customized.
