Abstract
The invention discloses a high-pressure centrifugal fan which comprises a base. A transmission part square box is installed on the base. A driving motor and a transmission shaft assembly are arranged on the transmission part square box. The driving motor is fixedly installed at one side of the transmission part square box. An output shaft of the driving motor is linked with the transmission shaft assembly through a coupler. A protection shield is installed outside the coupler. The transmission shaft assembly comprises a positioning seat and a standard shaft. A through hole penetrating the positioning seat is formed in the positioning seat. Bearing seats are arranged at the two ends of the through hole. The two ends of the standard shaft are located in the bearing seats respectively. One end of the standard shaft is connected with the output shaft of the driving motor. A bearing table is installed at one side of the transmission part square box. An impeller assembly is installed on the bearing table. The impeller assembly comprises a rear end pate, a worm shell and impellers. The bottom end of the rear end plate is fixed to the bearing table. The worm shell and the impellers are installed on the rear end plate. The other end of the standard shaft sequentially penetrates the rear end plate, the worm shell and the impellers.
