Design and Calculation of Magnetic Liquid Seal with Rectangular Pole Teeth

The principle of magnetic liquid seal with rectangular pole teeth structure is discussed in this paper, and the magnetic circuit design process of magnetic liquid seal with rectangular pole teeth structure is systematically discussed. Using the formula of pressure capability of magnetic liquid seal with rectangular pole teeth structure and equivalent magnetic circuit, the magnetic circuit of magnetic liquid seal with rectangular pole teeth structure was designed and calculated in detail according to the kirchhoff's law of the magnetic circuit. The design method of magnetic circuit in magnetic liquid seal with rectangular pole teeth structure proposed in this paper has important reference value to the design of magnetic liquid sealing device.
