4-70 centrifugal fan Product performance and technical parameters

1.4-70 type centrifugal fan structure type:
. 4-70 type centrifugal fan № 2.8 ~ 6 outlet position of 0 ° -225 °, at intervals of 45 °, transmission mode for the A -type transmission; № 7 ~ 12 outlet position of 0 °, 90 °, 180 °. , №. 7 ~ 12 transmission mode for the C -type transmission .
. 4-70 type centrifugal fan № 2.8 ~ 6 fans are allocated by the impeller, housing, air inlet and other units Direct motor and composition ;. № 7 ~ 12 addition to the above section, there are transmission parts and so on .
1 ) impeller by the 10 sheet backward arc type blade, curved front plate and the plate after the plate components. Are made of steel plate, and by the dynamic and static balance correction, air good performance, high efficiency and smooth operation.
2) The air inlet formed integrally mounted on the fan side. Parallel to the axial cross-section shape of the curve, the gas can smoothly enter the impeller, and the loss is small.
3) the transmission section 2 points from the spindle, bearing box, bearing, pulley components.
