[0021] Reference Figure 1As shown in the figure, the application of magnetic fluid sealing technology in sealing technology is one of its most important achievements. After decades of development, magnetic fluid sealing has been widely used in many fields such as national defense, aerospace, machinery, electronics, instrumentation, atomic energy, chemical industry, and pharmaceuticals.
