Abstract

The demanding for the shaft sealing of reactor at present is fully enclosed, zero-leakage, particularly dealing with the media which is corrosive, toxic, flammable and explosive. Therefore, the zero-leakage technology has been a key factor for the sealing of shafts. Actually, packing seal and mechanical seal are commonly used in sealing reactor, but neither can achieve zero-leakage; magnetic driving seal can be able to actualize zero-leakage, however, it is limited for unreliability and high cost. In order to achieve zero-leakage and enhance the seal reliability effectively, magnetic fluid (MF) seal was designed and applied in the shaft seal structure in this study. The main works are as following: Firstly, the overall structure and components, including flux sleeve and pole shoes, of the magnetic fluid seal are designed according to the operating conditions of reactor device. Secondly, the effect of different magnetic fluids and magnetic source constructions on pressure resistance was further studied by carrying out static and dynamic sealing experiments. The results obtained were discussed subsequently. Finally, after site commissioning of the manufactured seal components we put them into practical application. Results indicate that the problem of the sealing existing in reactor was settled efficiently. The sealing structure has optimized to further enhance the reliability of the MF seal.
