Description
本实用新型涉及磁力泵技术领域，尤其涉及一种具有流体散热结构的磁力泵。
磁力泵主要由底座、上壳、电机、磁力传动器以及叶轮等几部分零件组成。磁力传动器由转轴、内磁组件和联轴器组成，当电机带动转轴旋转时，磁场能穿透空气间隙和非磁性物质，带动与叶轮相连的内磁组件作同步旋转，实现动力的无接触同步传递，将容易泄露的动密封结构转化为零泄漏的静密封结构。
一方面，磁力泵的内磁组件在工作过程中会产生热量，热量的堆积会升高内磁组件的温度，温度过高会损坏内磁组件，严重影响内磁组件寿命；另一方面，轴承围绕转轴作高速同心旋转，作相对高速旋转运动的轴承与转轴接触处会因物体表面摩擦及震动产生大量的热能量，当此热能量无法消散并且不断积累后，对磁力泵的结构及性能会产生毁灭性的损坏。

参照图3、图7和图9，所述叶轮5上开设有进液孔53，所述内磁组件42上设有进液通槽423，所述进液孔53和所述进液通槽423相连通形成有进液流道48，所述进液流道48对应所述第一散热流道46设置为四条，并且液体从所述进液流道48流入后直接到达所述第一散热流道46和所述出液孔421，所述进液流道48与所述进液通道21、所述液体流道45、所述第一散热流道46、所述第二散热流道47、所述出液孔421和所述出液通道22相连通；当所述进液通道 21进入液体时，通过所述进液流道48能够快速将液体导流至所述液体流道45、所述第一散热流道46、所述第二散热流道47和所述出液孔421中并填满，即磁力泵启动的一刻，液体就在各液流通道中流动，实现对所述内磁组件42和所述轴承43进行实时地冷却降温。
进一步地，所述进液流道48、所述液体流道45、所述第一散热流道46、所述第二散热流道47和所述出液孔421设置有多个。

本实用新型的工作原理为：所述电机3通过所述联轴器41驱动所述转轴44旋转时，磁场穿透空气间隙和非磁性物质，带动所述内磁组件42和固定连接在该内磁组件42上的所述叶轮5作同步旋转，液体从所述进液通道21进入到泵内，并流到所述叶轮5转动的位置；
液体在所述叶轮5转动时会出现两种情况：
1、利用所述叶轮5的离心力，液体直接从所述出液通道22甩出；
2、所述叶轮5将液体从所述进液通道21带入所述液体流道45中，一方面，液体从所述液体流道45流经所述第一散热流道46后，从所述出液孔421和所 述出液缺口51流出，所述反水叶片52产生的离心力令一部分液体继续流回所述液体流道45中形成循环，另一部分液体从所述出液通道22甩出；另一方面，液体从所述液体流道45流经所述第二散热流道47后，流回所述叶轮5转动的位置，一部分液体在所述叶轮5的带动下流回所述液体流道45中形成循环，另一部分液体从所述出液通道22甩出。
以上内容是结合具体的优选实施方式对本实用新型所作的进一步详细说明，不能认定本实用新型的具体实施只局限于这些说明。对于本实用新型所属技术领域的普通技术人员来说，在不脱离本实用新型构思的前提下，其架构形式能够灵活多变，可以派生系列产品。只是做出若干简单推演或替换，都应当视为属于本实用新型由所提交的权利要求书确定的专利保护范围。
