Description

模块化紧凑型泵
本发明涉及一种模块化紧凑型泵(MCP)。MCP通常是海底多相泵。本发明的MCP是模块化且可扩展的，并且提供全电增强系统，该全电增强系统可以通过向多相烃井流中加入能量并通过降低井口压力来加速和改善在新井和成熟井中的油回收。MCP具有围绕静态轴旋转的集成电机叶轮。这减少了旋转动力问题。
本发明是一种模块化泵，其包括带有过程流体入口的入口侧端盖和带有过程流体出口的出口侧端盖和夹置在入口侧端盖与出口侧端盖之间的至少两个泵模块。每个泵模块包括壳体、壳体内部的封闭体积、至少两个泵级、至少一个冷却剂入口、至少一个冷却剂出口和用于连接至变速驱动器(VSD)的单独电力连接件。每个泵级包括具有转子的叶轮和围绕转子的定子，定子被设置成驱动转子。提供罐以在叶轮与定子之间形成屏障和密封件。
每个模块可包括压力补偿器，该压力补偿器在模块化泵的叶轮侧中的泵送介质与壳体内部的介电流体之间限制罐上方的压差。
至少一个冷却剂入口和至少一个冷却剂出口可以与围绕每个定子的螺旋形冷却剂通道流体连通。
模块化泵可以进一步包括位于至少两个模块之间的金属对金属面密封件。
泵可进一步包括在至少两个模块之间的聚合物面密封件。
每个模块可包括两个级。
附图的简短描述：
图1是本发明的实施方案的模块化泵的横截面。
参考附图对本发明的实施方案的详细描述：
图1是具有四个泵级6和两个模块7的模块化多级多相泵的横截面。泵通常是2-4-6-8-10-12-级泵。该配置不限制可以在每个模块包括操作模块所需的一切(与由公共电机驱动的模块相反)时堆叠的模块的数量。包括定子-转子-叶轮的集合称为一个级。每个模块7包括两个级6。入口侧端盖12包括具有过程流体连接件的入口14，并且出口侧端盖13包括具有过程流体连接件的出口15。每个模块7包括与螺旋形冷却剂通道11流体连通的一个或几个单独的冷却剂入口10，以及用于连接至VSD的单独的电力连接件16。每个级由其自身的VSD供电和控制。因此，模块7仅通过相对于泵送的介质或过程流体的一个或若干个端口连接。单独的电力连接件16通常是6销穿透器，为两个三相电力系统供应电力。
模块7之间的连接件形成金属对金属面密封件18。单独的环形密封件8围绕一个或若干个端口。转子4和叶轮5组件位于陶瓷圆柱体或“罐”3内，在泵送介质与壳体1内部的介电流体之间形成屏障。壳体1形成定子外壳和将工艺压力与环境海水压力分开的压力容器两者。陶瓷圆柱体或罐3优选地是非磁性或非导电材料。
压力补偿器19确保在泵送介质与定子周围的壳体1内部的介电流体之间的压差保持在某些限制内，以确保低泄漏，并且陶瓷罐3上的机械负载保持在设计规格内。连通通道从过程侧或泵送流体侧延伸到压力补偿器19的一侧。压力补偿器19的另一侧具有到定子2周围的介电流体的连通通道。过程通道输入的位置确保在圆柱形陶瓷罐3上的来自外部的轻微过压。这可以通过压力补偿器19中的机械弹簧来促进。
在壳体1内部的封闭体积17中的定子2围绕每个转子4。螺旋形冷却剂通道11围绕每个定子。壳体的内表面与内部圆柱体插入件的外表面一起形成螺旋形冷却剂通道11作为围绕定子的螺旋路径。外部冷却泵(未示出)循环冷却流体，从定子中去除热量。壳体1中的轴向通道还允许围绕定子2的介电油的自然对流，以进一步改善从热体积到冷体积的热传递。每个定子具有通过壳体1的其冷却剂流体入口端口。模块7中的两个定子2具有通过壳体1的共同冷却流体出口端口。
每个陶瓷罐3位于定子2与转子4之间。陶瓷罐3将封闭体积17密封，与过程流体分开，同时允许定子驱动转子。柱螺栓9将入口端盖12、出口端盖13和模块保持在一起。柱螺栓9和泵的总体设计简化了泵中模块的数量的改变，以适应各种电力要求和需求。
级6的叶轮5因此具有共同的中心轴线并且围绕泵的静态中心部分旋转。过程流体在围绕中心的环形通道中流动。每个模块7具有垂直于中心轴线的平面接触表面，用于与相邻模块或端盖12、13接触。平面接触表面形成金属面密封件。
定子2包括绕组，并且转子4包括固定磁体。转子4的外表面、罐3和定子的内表面是圆柱形的。因此，每个叶轮5沿着叶轮的周边由转子4驱动。
