如果能够提供一种离心泵, 使其同时具备惯性轮的作用, 在比如发 电站的一些应用场合, 将会显得尤其有意义。
【发明内容】
为了解决以上问题, 本文实施例提出了一种离心压力泵。

当旋转构件旋转时, 工作液体经入液口进入旋转压力腔体, 若干区 域内的液体与旋转压力腔体一起转动, 加大旋转构件的离心势能, 然后 通过开口进入集液通道并最终从出液口排出。 其中, 入液口的大小大于 出液口的大小。
根据一优选实施例, 外壳体包括第一侧壁、 第二侧壁以及连接于第 一侧壁和第二侧壁边缘的第一弧形壁, 此三者形成圓形泵腔, 入液口设 于第一侧壁上, 入液口上进一步设有入液通道, 第二侧壁上设有轴孔, 以允许旋转轴插入轴孔, 出液口设于第一弧形壁上, 出液口上进一步设 有出液通道。
根据一优选实施例, 旋转压力腔体包括第三侧壁和设于第三侧壁边 缘的第二弧形壁, 第三侧壁以一定距离与第二侧壁间隔开, 旋转轴贯穿 第二侧壁, 并在旋转轴的一端处与第三侧壁固定连接, 若干开口设于第 二弧形壁上, 若干口上进一步设置有导管, 导管倾斜设置, 以引导液体 周向进入集液通道。

图 4是本文实施例的离心压力泵的一实施例的工作原理示意图。 【具体实施方式】
下面结合附图和实施例进行详细说明。 在附图中采用相同或者类似 的图标记来标示类似的部件, 为了筒洁起见, 有时同一部件在不同视图 中出现, 但是仅在某些视图中对其进行了标示。 为了表示方便, 图中的 侧壁、分隔片以及壳体等构件均以线条表示。并未显示其宽度或者厚度。
请一并参见图 1和图 2, 图 1是本文实施例的离心压力泵的一实施 例的外部结构示意图; 图 2是本文实施例的离心压力泵的一实施例的剖 面示意图。
大体而言,本文实施例的离心压力泵主要包括外壳体 10以及旋转机 构 (未标识)。 下面分别介绍二者的具体结构。
离心压力泵的外壳体 10主要包括: 第一侧壁 12、 第二侧壁 14以及 第一弧形壁 16。 该第一弧形壁 16显示为规则的一段圓周, 但是, 不受 限于此,根据需要, 此第一弧形壁 16也可为表面不规则的其他形状的表 面。
第一侧壁 12是具有一定厚度的板料, 其上设有入液口 121 , 该入液 口 121上进一步设有入液通道 122; 第一弧形壁 16上设有出液口 161 , 该出液口 161上进一步设有出液通道 162。
第二侧壁 14是具有一定厚度的板料, 第二侧壁 14与第一侧壁 12 具有相同的外围形状以及外围尺寸。 不同的是, 第二侧壁 14上设有轴孔 141 , 轴孔 141上匹配设置有轴承机构 142, 轴承机构使用密封防水装置 保护, 以防止液体通过轴孔 141流出, 同时可延长轴 7 座和轴 7 的使用 寿命。
第一弧形壁 16也是具有一定厚度的板料, 第一弧形壁 16连接于第 一侧壁 12和第二侧壁 14的边缘, 此三者固定连接形成圓形泵腔(未标 识) 。
下面请一并参见图 3和图 4, 图 3是本文实施例的离心压力泵的一 实施例的内部结构示意图; 图 4是本文实施例的离心压力泵的一实施例 的工作原理示意图。
本文实施例的离心压力泵的旋转机构主要包括: 旋转压力腔体 22 , 旋转轴 24以及多个分隔片 26。
旋转压力腔体 22具有圓形中空结构, 该旋转压力腔体 22包括第三 侧壁 221和设于该第三侧壁 221边缘的第二弧形壁 222, 第三侧壁 221 与第二弧形壁 222均是具有一定厚度的板料。 该第三侧壁 221以一定距 离与第二侧壁 14间隔开, 该第二弧形壁 222上设有若干开口 223。 在本 的实施例中, 仅示意性地示出三个开口 223 , 当然, 开口 223的数量可 以根据需要进行增加或者减少。 在优选实施例中, 该开口 223上进一步 设置有较短的导管 224 , 该导管 224倾斜设置以在旋转压力腔体 22旋转 时引导旋转压力腔体 22内的液体周向进入集液通道 18并最终从出液口 161排出。
第二弧形壁 222在与第三侧壁 221 相对的一侧还具有收口部 2221 (参见图 2所标示)。 收口部 2221大致呈圓形, 且在圓形的中间具有中 心开口 (未标识) , 以便于来自入液口 121的液体通过该中心开口进入 旋转压力腔体 22。 需要说明的是, 为了清楚显示内部结构, 在图 3的剖 面图中, 未显示第二弧形壁 222的收口部 2221。
旋转轴 24的一端贯穿第二侧壁 14 , 在本实施例中, 旋转轴 24与第 三侧壁 221 的外侧固定连接, 该固定连接的可以采用螺丝、 焊接等方式 实现。 也就是说, 当旋转轴 24在外力带动作用下旋转时, 包括第三侧壁 221和第二弧形壁 222的旋转压力腔体 22在外壳体 10的圓形泵腔内一 同旋转。 旋转轴 24的另一端向外延伸, 其上匹配设置有轴承机构 142, 旋转轴 24在外力作用下开始旋转。
分隔片 26分布式固定于旋转压力腔体 22 的内部, 并且分隔片 26 固定于第二弧形壁 222上的一端靠近相应的开口 223设置, 使得从该若 干开口 223 出来的液体具有较大的势能。 在本实施例中, 仅示意性地示 出三个分隔片 26, 当然, 分隔片 26的数量可以根据需要进行增加或者 减少。 分隔片 26也是具有一定厚度的板料, 分隔片 26将旋转压力腔体 22所包围形成的腔室划分为若干区域, 分隔片 26的一侧连接第二弧形 壁 222, 另一侧连接第三侧壁 221。 图中所示的若干区域的个数为三个, 分隔出的区域的个数与分隔片 26的个数相对应,每个分隔区域上对应设 置有一个开口 223。 在工作时, 第三侧壁 221、 第二弧形壁 222以及分隔 片 26连同旋转轴 24—起旋转。
下面结合图 4来介绍离心压力泵的工作情况, 首先, 整个离心压力 泵内充满液体, 当旋转轴 24在外力带动作用下开始旋转时(如图 4中箭 头 R所示的方向旋转) , 离心压力泵内的液体开始向外输出, 同时, 入 液口 121开始吸进液体, 并充满由分隔片 26所划分的若干区域, 由于第 二弧形壁 222上设置的开口 223较小,旋转压力腔体 22内的液体在其旋 转的过程中同时充当了离心配重块的作用, 并储蓄有较大的离心势能, 使得从开口 22进入集液通道 14的液体携带较大势能并从出液口 12射出, 由此可实现对其他能量转换设备做功。图 2中的虚线 W示意性地显示了 离心压力泵工作时液体的大致流向。
需要指出的是, 在本文实施例中提到的 "第一" 、 "第二" 以及 "第 三" 等用语仅是根据需要采用的文字符号, 在实务中并不限于此, 并且 该文字符号可以互换使用。
本发明结构筒单、 设计新颖, 相对于现有技术的泵腔体而言, 新设 计出了第二腔体, 也即旋转压力腔体 22所形成的腔体。入液口 121的大 小大于出液口 12的大小, 从而令大量液体留于腔内, 利用第二腔体内的 液体作为离心配重块, 增强液体的势能。 是一种理想的压力泵。 与现有 技术中的其他压力泵相比, 本文实施例的离心压力泵具有更好的能量转 换效率, 该装置可作为一般的抽水、 抽油装置, 亦可作为汽车的动力转 换装置, 发电机的动力驱动装置, 以及其他一些需要动力驱动的设备。 在上述实施例中, 仅对本发明进行了示范性描述, 但是本领域技术人员 在阅读本专利说明书后可以在不脱离本发明的精神和范围的情况下对本 发明进行各种修改。
