4-68 centrifugal fan
Patent No.:
★ Use
4-68 centrifugal fan can be used as a general plants and large buildings indoor ventilation . Is used to enter the gas , can also be used to export gas . By gas should not spontaneous combustion , harmless , no corrosion of the steel material gases. Gas was allowed to contain viscous substances contained dust and hard particles should not exceed 150mg / m3.
★ MODEL
From the motor side of the face , the impeller rotates clockwise , called a cyclone , the " right" ; impeller counterclockwise rotation, called L- blower to " left".
Fan outlet location to the chassis of the outlet angle . Machine No. No2.8 ~ 6.3 factory are made of one kind of type, the use of units as required , and then install into the desired position , the order is not required to specify. No8 ~ 12.5 export position adjustment range 0o ~ 22.5o, interval 45o. Machine number No16, 20 made from a fixed three kinds of export position ; 0o, 90o, 180o, can not be adjusted when ordering .
The fan drive with A, B, C, D four kinds .
Machine No. No2.8 ~ 5 with A -type transmission , No6.3 ~ 12.5 using C, D type transmission , No16 ~ 20 using B -type transmission .
★ Structure
Machine No. No2.8 ~ 5 mainly by the impeller , casing, inlet and other units assigned direct-motor and components. No6.3 ~ 20 In addition to the above section , there are other transmission parts .
( 1 ) impeller 12 backward curved airfoil blades welded to the wheel cover with flat **** middle . Are steel manufacture, and the dynamic and static balance correction, air , good performance, high efficiency and smooth operation.
( 2 ) ordinary steel chassis is welded snail shape. Case made of two different types . No2.8 ~ 12.5 chassis made whole, and can not be disassembled . No16 ~ 20 casing made of two open , grab the horizontal plane into two halves along the outer , with the gong bolt connection.
( 3 ) made of convergent inlet streamline the overall structure , mounted on the fan side , parallel with the axial load surface for the shape of the curve , the gas can successfully enter the impeller, and a smaller loss
Transmission part of the spindle , bearing housing, bearings , pulleys or couplings components.
