Y5-47 type Boiler centrifugal induced draft fan It is a boiler induced draft fan with a maximum total pressure efficiency of 90.5% designed for industrial boilers (1-20 T / h) with various coal qualities and smoke and dust removal devices. It can be selected for those with similar air intake conditions and dual performance, but the maximum temperature shall not exceed 250 ℃.
At present, there are many series of industrial boilers, the quality of burning coal is very different, the resistance of dust collectors is different, the air volume and air pressure of induced draft fan are different. In order to adapt to the above situation, considering the economy of fans, except that the induced draft fan with 20t boiler needs large power and the (D-type) coupling is directly driven, the others are driven by V-belt (C-type), which can not only be driven by one fan, but also driven directly by D-type coupling In addition, it is convenient to use the same type of fan to meet the requirements of different types of fan speed, and it is convenient to use the same type of fan to meet the actual requirements.
The induced draft mechanism is single suction, and the machine numbers are No. 4, 5, 6, 8, 9, 12 and 12.5.
The induced draft fan can be made into two types of left rotation or right rotation.
The outlet position of the fan is indicated by the air outlet of the casing. The "left" and "right" can be made into three angles of 0 °, 90 ° and 180 °.
The fan is composed of impeller, casing, air inlet, transmission part, regulating door, etc.
