T4-72 centrifugal fan
Product introduction :

T4—72 centrifugal fan can be used for general ventilation, and its use conditions are as follows:
1. Application place: As indoor ventilation for general factories and large buildings, it can be used as input gas or output gas.
2. Gas types: air and other unnatural gases that are harmless to the human body and non-corrosive to steel materials.
3. Impurities in the gas: No viscous substances are allowed in the gas, and the dust and hard particles contained in the gas are not more than 150mg / m3.
4. The temperature of the gas: it should not exceed 80 C.
№3 ~ 6 air outlet position adjustment range is 0 ~ 225 , the interval is 45 , the transmission method is A type transmission; №7 ~ 12 air outlet positions are made of three fixed types: 0 , 90 , 180 , Can not be adjusted; №7 ~ 12 transmission mode is C-type transmission. The fan can be made into two types of right rotation and left rotation.
№3 ~ 6 fans are mainly composed of impellers, casings, air inlets and other parts distributed directly connected motors; №7 ~ 12 have transmission parts in addition to the above parts.
The impeller is composed of ten backward-inclined circular solitary thin-plate blades, curved front discs and flat back discs, all of which are made of steel plate and corrected for static and dynamic balance. It has good air performance, high efficiency, low noise, and stable operation.
The casing is made of two different types. The casings of №3 ~ 12 can not be disassembled as a whole; the casings of №14 ~ 20 are made into two-open type, divided into two halves along the mid-level horizontal plane, and connected by bolts. The air inlet is made as a whole and is installed on the side of the fan. The cross section parallel to the axial direction is a curved shape, which allows the gas to enter the impeller smoothly and the loss is small. The transmission part is composed of a main shaft, a bearing box, a rolling bearing, and a pulley.
