Steel Double Inlet Centrifugal Fan Blower 220V 380V Color Custom 1 Year Warranty

Double inlet fan forward curved centrifugal fan fluid machinery air conditioning equipment industrial furnaces

Structural characteristics of double suction F model:

1.1 compared to the past, because of the low resistance of the preheater, the constant improvement of the ability of rotary kiln, the fan impeller diameter decrease relatively, impeller width, speed increased, this not only reduces the manufacturing difficulty, also meet the requirements of the cement production low resistance winds, coaxial double impeller, combined with the expanding of inlets, makes the fan axis, compared with the past has become longer, In order to improve the limit speed of the fan, the middle of the shaft becomes thicker than in the past, so the characteristics of the large double suction F type fan are two support spans are large, one shaft double impeller, and two air intakes.

1.2 in a large double suction fan on the configuration of the F type, due to large equipment, and at a relatively high temperature operation, when stop, to prevent the shaft because of temperature stress and bending under the action of gravity, are usually equipped with quick action, used for cold, to turn over of shaft, the low-speed rotation when hot, because the fan air volume is very big, In order to meet the wind pulling requirements under different production states, it is generally equipped with variable frequency drive motor or speed regulating bias coupler to adjust the speed, which is used for air volume regulation under different production states.
