More Information
Summary:The utility model discloses an off-gas induced draft fan. The off-gas induced draft fan comprises an air inducing body, a power plant, a cooling device and an oil supply device. According to the off-gas induced draft fan, a middle shaft is arranged between an impeller shaft and a motor so as to add a heat dissipation section, and the cooling device is additionally arranged on the middle shaft, so that the heat dissipation speed of the induced draft fan is further increased and influences on the motor from heat conduction of the impeller are reduced. In addition, the off-gas induced draft fan is further provided with an automatic refueling device, so that the lubricating effect between the middle shaft and a bearing seat is guaranteed.
