摘要
文章讨论了永磁打捞器的工作原理 ,并根据要求设计和开发了 3 92kN( 40 0kg)稀土永磁打捞器。该打捞器体积小、性能稳定、无能耗 ,克服了过去打捞器 (如 ,AlNiCo材料 )使用不稳定的缺点 ,可广泛用于油田钻井、探矿钻井及海洋。
In this paper,the working principle of magnetic force salvager is discussed,and then 3.92 kN type of NdFeB magnetic force salvager has been designed and developed.Which is of small volume ,stable properties,no power consumption,being advantageous over AlNiCo one with properties decreasing greatly during working .It will be widely used in the oil field,the ocean and the rivers etc.
