摘　　要：磁力联轴器中内外转子间的隔离套是磁力泵实现无泄漏的主要零件,由于磁力联轴器工作时,隔离套便处在变化的磁场中,则其内部将产生涡流,导致涡流损耗和传递效率降低。本文推导了隔离套中涡流损耗公式,分析了对磁场和涡流损耗的影响因素,提出了减小隔离套涡流损耗及对磁场影响的措施。Insulation shell in a new induction shaft coupling is a main element to solve leakiness of magnet pump, it often works in changing magnetic field so that eddy current is produced, and eddy current results in wastage and decreasing the efficiency . Some formulas are deduced and used to calculate the wastage of eddy current, and analyse factors about magnetic field and wastage of eddy current, at last measures for minishing the wastage of eddy current and the influence of magnetic field are put forward.
