The invention provides a magnetic drive pressure-bearing hydrogen circulating fan, relating to the fields of power plants, chemical industry, pharmacy industry and environmental protection industry. The magnetic drive pressure-bearing hydrogen circulating fan comprises a motor which comprises an output shaft, a main shaft is arranged at one side of the motor, an impeller is connected with one end of the main shaft, a volute is arranged outside the impeller, the other end of the main shaft is connected with a driven magnet, the output shaft of the motor is connected with a driving magnet which is arranged at the periphery of the driven magnet, a hollow isolating seal cartridge is arranged between the driving magnet and the driven magnet, a water inlet connector and a water outlet connector are connected with the hollow isolating seal cartridge hermetically, a bearing bush is sleeved outside the main shaft, one end of the bearing bush is connected with the volute, the other end of the bearing bush is connected with a flange fixedly, the flange is supported on the main shaft through a bearing, a bearing cap is arranged at one side of the bearing, is sleeved on the main shaft and is connected with the flange through a screw. A permanent magnet coupler is used for power transmission of the magnetic drive pressure-bearing hydrogen circulating fan, and the impeller, the main shaft and the driven magnet are sealed in the volute and the hollow isolating seal cartridge, thereby ensuring a no-leakage effect.
Description
technical field [0001] The invention relates to the fields of power plants, chemical and pharmaceutical industries, and environmental protection industries, and in particular to a sealed cycle power or booster device for hydrogen and helium-hydrogen gas of a hydrogen-cooled generator. Background technique [0002] The magnetically driven pressurized hydrogen circulation fan is mainly used in the condensing or adsorption dehumidification system of the hydrogen-cooled generator. The magnetically driven pressurized hydrogen circulation fan can work normally when the generator is shut down, cranked or the pressure of the generator fan is insufficient. The output shaft of the motor and the main shaft of the existing magnetically driven pressurized hydrogen circulation fan are connected by a common coupling, and it is not sealed, which is prone to leakage. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and ...
