Abstract
The utility model discloses an explosion-proof type fan is equipped with a motor in the motor chamber, and the motor tip is equipped with the motor flange, and the motor flange of motor passes through fixing bolt and assembly plate fixed connection, and the output shaft of motor runs through behind motor flange, assembly plate, the assembly beam with above-mentioned impeller fixed connection, is equipped with the rubber gasket between motor flange and the assembly plate. The technical effects are as follows: 1. the motor is changed into a V5 flange structure, so that the installation is convenient. 2. A coupler and a sealing stuffing box are eliminated, and a mode that a motor and an impeller are in a straight chain is adopted. Therefore, the quick-wear parts of the fan are reduced, and the service life of the fan is greatly prolonged. 3. The fan shell can shorten the size and save space due to the elimination of the coupler and the sealing stuffing box.
