非导磁管材自控检测仪的研制

Development of Automatic Detector for Non magnetic Pipe

阐述了非导磁管材自控检测仪的检测原理，设计了该仪器的关键结构—磁流体线性密封结构和控制电路。该检测仪能检测非导磁管材引起泄漏的缺陷。

In this paper,the principle of an automatic detector for non magnetic pipe is presented,simultaneously,the key structure of the detector,ferrofluid linear seal and control circuit are designed.The instrument can detect the defects which give rise to leakage.
