Description

Energy-saving vertical shaft seal fan
Technical Field
The utility model relates to the field of energy-saving equipment, in particular to an energy-saving vertical shaft seal fan.
Background
The shaft seal fan used by the shaft seal system of the open-door power generation branch company is a horizontal centrifugal fan, and the operation of years proves that the shaft seal fan has a plurality of defects, is large in size and has heavy impellers. The efficiency is low and the sealing performance is poor. The sealing joint of the fan impeller and the bearing seat is frequently subjected to steam leakage and is connected with the bearing seat in series, so that oil is emulsified, and the bearing is damaged. Most of impellers are made of steel materials and are easy to rust and perforate. When the impeller is severely corroded, dynamic balance is lost, vibration is caused, axial movement is performed in a stringing mode, and a coupler bolt is frequently worn and broken. The service life of the rotating part is short, and the maintenance and the replacement are frequent, such as a bearing and a shaft, so that the maintenance cost is increased; therefore, the maintainer changes the horizontal centrifugal shaft seal fan type into the vertical type through research and discussion, meanwhile, the middle connecting structure is simplified, and the middle connecting shaft, the bearing seat and the coupling are removed. The motor shaft is directly connected with the impeller, the impeller is also changed into a light aluminum alloy structure, the steam inlet and the pipeline are changed into the bottom of the fan to be connected, and the steam outlet and the pipeline are changed into the side surface of the shell of the shaft seal fan impeller. All the defects of the horizontal shaft seal fan are reasonably overcome through transformation, the structure is simple, the assembly is convenient, and the maintenance and the repair are easy.
