The Design of Hollow Shaft Sealed
Abstract
Magnetic fluid is a new-style magnetic material. Because this seal has good seal performance, almost no leakage and long service life etc. So widely used in dynamic seals require special high places, Such as number furnace, ion sputtering, chemical vapor deposition, ion plating, liquid crystal display equipment. and the computer hard disk, robot and military products, such as environmental equipment or part in higher requirements also began to application
In this paper, the principle of the seal is magnetic properties, characteristics and application of test requirements and aspects of magnetic sealing technology is introduced. And summarizes the design procedures of the magnetic sealing device,Introduced the general magnetic sealing device design method. Considering the factors that affect the sealing properties of hollow shaft sealing device design.
