Abstract

一种磁悬浮型离心泵，包括蜗壳(200)、静磁环(22)和转子(100)；蜗壳(200)具有悬浮腔、介质进口和介质出口，转子(100)位于悬浮腔内部，静磁环(22)固定于蜗壳(200)，转子(100)包括转子本体和定位于转子本体的动磁环(16)；动磁环(16)与静磁环(22)同轴且嵌套配置以限制转子本体与蜗壳(200)的径向位置；转子本体还固定有磁钢组件(14)，磁钢组件(14)包括N个沿周向排布的第一磁钢(141)，所有第一磁钢(141)的磁极交错布置；蜗壳(200)的两端还封装有驱动线圈组件(21)，两个驱动线圈组件(21)与磁钢组件(14)配合以提供转子本体沿轴向运动的轴向力及旋转力。通过转子(100)两端设置的磁钢组件(14)和蜗壳(200)上相应的驱动线圈组件(21)提供轴向力，无需额外的线圈和传感器组件，可以大幅度降低了体积和重量，从而实现血泵的高可靠性和小型化。
