Magnetic fluid high sealing parts

Product introduction

Magnetic fluid sealing device is composed of non-conductive magnetic housing, bearing, magnetic pole, permanent magnet, magnetic shaft and magnetic fluid. Under the effect of uniform and stable magnetic field, the magnetic fluid is filled in the set space, and a multi-stage "O-type sealing ring" is established, so as to achieve the effect of sealing Each stage of sealing ring can generally withstand a pressure difference greater than 0.15 to 0.2 atmospheres. The total pressure is the sum of the pressure differences between the various levels, and is generally designed to be 2.5 atmospheres, which fully meets the needs of vacuum sealing. Our magnetic fluid sealing devices have a variety of installation structures, and can also be manufactured according to the special requirements of customers.

Today, our products are widely used in crystal growth, ion etching, liquid crystal regeneration, chemical vapor deposition, vacuum coating, vacuum reactor and other equipment. In some special fields, such as ultra-high-speed dynamic sealing devices, ultra-high pressure (ultimate pressure: 14Mpa) dynamic sealing devices and other environments, our products have also been effectively applied.
