具体实施方式
详细地转向附图，在图1至图3的优选实施例中公开了具有磁性接合的齿轮泵。齿轮泵包括总体指定为10的泵外壳，所述泵外壳由第一外壳部分12和第二外壳部分14限定。所述部分被螺接在一起。泵外壳10进一步包括轴承盖16和泵轴支撑件18，所述轴承盖16通过被螺接到第一外壳部分12来闭合泵外壳10的第一端，所述泵轴支撑件18闭合泵外壳10的第二端并且被螺接到第二外壳部分14。轴承盖16包括通过驱动轴20的动力用耦合件，所述驱动轴20被安装在轴承22中。驱动轴20能够被键接到旋转动力源(未示出)。泵轴支撑件18包括盖24。流体进口(未示出)和流体出口26通常延伸到泵外壳10中。
可旋转磁性驱动组件包括杯形的驱动构件28。围绕由杯形构件28限定的轴向凹部以环形布置方式保持磁铁30。构件28上的毂32被安装到驱动轴20，并且被键接为随之旋转。杯形部分在泵外壳10内从毂32悬臂伸出，形成用于磁性耦合的圆柱形环绕件。
可旋转从动磁性组件包括大致圆柱形的磁铁安装件34，该磁铁安装件34具有围绕周边的磁铁36，以限定被物理地设置为与用于磁性对齐的磁铁30基本上对齐的磁性部分，从而实现磁性耦合。利用可旋转磁性驱动组件和可旋转从动磁性组件，磁性耦合被常规布置。
在泵轴支撑件18处被固定到泵外壳的复杂的不动安装轴38限定两个圆柱形轴40、42，所述两个圆柱形轴40、42具有被轴向且横向移位的轴线。径向安装凸缘44位于两个轴40、42之间。安装轴38通过到安装凸缘44的紧固件46并且通过圆柱形轴42上的残端48被安装到轴支撑件18，所述残端48被定位在轴支撑件18中的腔室50内。这种布置在结构上将轴40悬臂伸出到磁性耦合内。安装凸缘44在圆柱形轴40的一端处进一步限定面向齿轮泵的驱动端的肩部。
为了将由磁铁30、36限定的无缝磁性耦合分开，圆柱形罐在杯形驱动构件28的轴向凹部内的磁铁30、36之间延伸。罐在磁铁30、36之间是薄壁的，并且具有非铁磁材料以避免干扰磁性耦合。罐52通过径向安装凸缘54被固定到泵外壳10，以实现密封接合。
安装凸缘54被方便地固定在第一外壳部分12与第二外壳部分14之间。在罐52的另一端处，罐盖56闭合罐52。罐盖56接收圆柱形轴40的端部，这有助于定位罐52的薄壁。罐盖56还限定面向泵外壳10的泵轴支撑件第二端的肩部。罐盖56上的中心旋钮延伸到泵外壳附近。如果限定的肩部被推得太远，这将会防止罐盖56过度偏转。
泵转子58可固定到齿轮泵中的可旋转从动磁铁组件的磁铁安装件34。泵转子58主要被定位在泵外壳10的第一外壳部分12内，并且包括如具有在图2和图3中最佳可见的齿60的环形齿轮。泵转子58上的向内延伸的径向安装凸缘62紧靠可旋转从动磁铁组件的磁铁安装件34的近端。大齿轮64围绕横向移位的圆柱形轴42被可旋转地安装在衬套66周围。可旋转的大齿轮64与泵转子58的环形齿轮的齿60啮合。该齿轮然后限定与泵的流体进口和流体出口26连通的齿轮泵。
可旋转承载器68被安装在圆柱形轴40周围。磁铁安装件34包括完全延伸通过其中的同心圆柱形腔室以接收可旋转承载器68。磁铁安装件34和可旋转承载器68被示为在其之间限定环形腔室以减少材料和重量。O形环可以被放置在两个部件之间的接触表面处，如图3所见，以将环形腔室与工作流体隔离开来。
径向附接凸缘70位于邻近泵转子58的可旋转承载器68的端部处。该径向附接凸缘70在泵转子58的向内延伸的安装凸缘62外面。等距地间隔开的三个紧固件72延伸通过径向附接凸缘70、向内延伸的径向安装凸缘62和磁铁安装件34的端部中的安装孔，以将这三个元件固持在一起，使得它们能够作为组件围绕圆柱形轴40旋转。
可旋转承载器68包括通过其中的镗孔74以接收轴40。在齿轮泵中，镗孔74包括两个平面轴承位置76、78以固持用于围绕轴40同心地安装磁铁安装件34和泵转子58的衬套80、82。围绕镗孔74的可旋转承载器68的端部包括止推轴承位置84、86以分别固持止推衬套88、90，以面向轴40的安装凸缘44上的肩部和罐盖56。
可旋转承载器68具有提供用于衬套80、82、88、90的正固持和布置的机制的属性。另外，能够在不从其安装和管道系统移除泵的情况下接近如在图2和图3中图示的整个可旋转子组件。通过泵轴支撑件18的移除，安装轴38能够与大齿轮64一起撤出。这暴露出紧固件72。可选地，如在图2和图3中图示的整个组件能够在紧固件72处于适当位置的情况下被撤出。更重要地，紧固件72能够被移除，从而允许可旋转承载器68被撤出，同时使泵的其余部分(包括转子58和磁铁安装件34)处于适当位置。泵和可旋转承载器68中的所有衬套能够被检查和更换。紧公差的磁性耦合件的衬套主要能够作为一个单元被接收并且如此被安装。
在图4至图6的优选实施例中公开了具有磁性接合的离心泵。该泵包括总体指定为10的泵外壳，所述泵外壳由第一外壳部分12和第二外壳部分100限定，所述第一外壳部分12和第二外壳部分100以常规方式不同于齿轮泵的外壳部分14以适应离心泵机制和流动。部分12和100被螺接在一起。泵外壳10进一步包括轴承盖16和泵轴支撑件102，所述轴承盖16通过被螺接到第一外壳部分12来闭合泵外壳10的第一端，所述泵轴支撑件102在泵外壳10的第二端处并且被螺接到第二外壳部分100。如在具有轴承盖16的齿轮泵中，外壳10的第一端保持驱动轴20和轴承22。泵轴支撑件102包括到泵的流体进口104。流体出口106通常从泵外壳10延伸。不动安装轴108在泵轴支撑件102处被固定到泵外壳。这种布置在结构上使轴108悬臂伸出通过泵转子进入磁性耦合件。如在齿轮泵中，不动安装轴108也接合罐盖56。
离心泵中的磁性耦合件与齿轮泵的磁性耦合件完全相同。这包括可旋转磁性驱动组件、可旋转从动磁性组件和圆柱形罐。然而，在齿轮泵中被示为单独圆柱形元件34的可旋转从动磁铁组件的磁铁安装件112作为其延伸的裙部与图4至图6的离心泵中的泵转子114一体形成。磁铁安装件112包括面向泵转子114的向内延伸的肩部116。这种一体构造也同样适于齿轮泵优选实施例。
从磁铁安装件112延伸的这种集成式旋转元件的泵转子部分114主要被定位在泵外壳10的第一外壳部分12内，并且包括如在图5和图6中最佳所见的闭式环形叶轮118以作为离心泵操作。内叶轮122被安装到集成式旋转元件。内叶轮122具有允许它穿过前覆盖物124中的中心开口的直径，所述前覆盖物124被固定到环形叶轮118或与环形叶轮118一体。环形叶轮118和内叶轮122包括对齐的叶片，使得当被组装好时两者作为一个单元操作以具有通过叶轮组件的流动的连续性。
具有中心镗孔128的可旋转承载器126被安装在不动安装轴108周围。磁铁安装件112进而包括完全延伸通过其中的同心圆柱形腔室以接收可旋转承载器126。磁铁安装件112和可旋转承载器126被示为在它们之间限定环形腔室以减少材料和重量。O形环可以被放置在两个部件之间的接触表面处，如图6可见，以将环形腔室与工作流体隔离开来。
径向附接凸缘130位于可旋转承载器126的端部处。该径向附接凸缘130延伸以配合向内延伸的肩部116。叶轮118的内叶轮122配合径向环形凸缘的另一侧。径向附接凸缘130具有不大于叶轮118的内叶轮122的直径的直径，从而允许它穿过叶轮118和前覆盖物124中的中心开口。等距地间隔开的三个紧固件132延伸通过内叶轮122、径向附接凸缘130中的安装孔并进入向内延伸的肩部116以将这三个元件固持在一起。通过移除紧固件132，叶轮118的内叶轮122和可旋转承载器126能够从泵外壳10撤出。
图4至图6的第二实施例中的可旋转承载器126包括在中心镗孔128中的两个平面轴承位置134、138。在该离心泵中，衬套136、140在平面轴承位置134、138处与可旋转承载器126一体形成。这些衬套136、140将磁铁安装件112和泵转子114旋转地且同心地安装在不动安装轴108周围。围绕镗孔128的可旋转承载器126的朝向离心泵的驱动端的端部包括止推轴承位置142。而且在离心泵中，止推衬套144在止推轴承位置142处与可旋转承载器126一体形成。该止推衬套144面向罐盖56。
像齿轮泵一样，可旋转承载器126具有提供用于衬套136、140、144的正固持和布置的机制的属性。另外，能够在不拆卸磁性耦合件或不从泵移除泵转子114并进而从其安装移除泵的情况下接近如在图5和图6中示出的整个可旋转子组件。通过移除泵轴支撑件102，暴露出紧固件132。紧固件132能够被移除，从而允许可旋转承载器126被撤出，同时使泵的其余部分(包括转子114和磁铁安装件112)处于适当位置。
