磁力驱动密封装置在钻井液动态试验中的应用

Application of magnetic coupler on drill fluid dynamic test

简要地介绍磁力驱动密封装置的结构、工作原理、传动力矩计算及高压金属隔套选材要求。采用隔离平衡的方法,解决了在满罐导磁试验介质的条件下,磁力驱动密封装置的应用问题。试验证明,磁力驱动钻井液动态试验仪性能良好。

This article introduces a magnetic coupler used as the sealing unit on the drill fluid dynamic testing meter, describes its structure and operating principle, and discusses the calculation of driving torque and the selection of material for high-pressure metallic bushings. The effect of the sealing unit under full-tank magnetic medium condition is accomplished by isolated balancing.
