摘要
介绍了一种新型密封———铁磁流体密封的结构与工作原理 ,“铁磁流体”在密封间隙中发挥磁场作用 ,形成强韧的流体膜 ,阻止泄漏。该密封从维修服务、使用工作量、工作程度等方面 。
A new seal--liquid ferromagnet seal was introduced, the colloid solution which made from putting the ferromagnet minuteness into the lower volatility liquid was made for seal in sand pump. The strong film could be produced to prevent leakage. Some advantages for the liquid ferromagnet seal in maintenance was introduced.
