Description

泵机组
技术领域
本发明涉及一种具有电驱动电机的泵机组,该驱动电机具有定子壳体和至少一个与该定子壳体相连接的接线盒。
背景技术
泵机组,例如供热循环泵机组或非饮用水循环泵机组这样的循环泵机组,一般具有设置在管状定子壳体中的电驱动电机,其中,定子壳体在一轴向端部上与泵壳体相连接,在泵壳体中有至少一个叶轮为了输送液体而旋转。在已知的泵机组中,大多数情况下是从外面在定子壳体上设置电子装置壳体或接线盒,并在电子装置壳体或接线盒中设置电连接元件和电气和/或电子元件,以控制驱动电机。这些电子元件特别是可以包括变频器。这种接线盒可以沿外周或轴向设置在背对泵壳体的定子壳体端部上。
这种泵机组的接线盒可以具有用于电连接的插接区域,电连接电缆可以通过对应的连接插件插接在该区域上。替代地还公知有接线盒,其在外侧上具有可拆卸的盖并在壁上具有电缆穿管。电缆可以通过电缆穿管引入接线盒的内部,然后卸下盖在接线盒内部连接在连接端子上。此外,接线盒具有用于与定子壳体内部的定子线圈连接的电接头。在此还有公知的插接触点,其必须设置在接线盒的面对定子壳体的一侧。
也就是说,接线盒必须具有多个用于电连接元件的开口和用于在其外侧上连接连接导线的盖。这就要求复杂的结构。但这特别是会造成密封方面的问题,因为必须在各个开口上设置密封件,以防止湿气渗入到接线盒中。
发明内容
因此本发明的目的在于对泵机组进行改进,以使接线盒能够以简单的方式与定子壳体内的线圈以及电连接导线相接触,并且还能够容易地进行密封。该目的通过具有如权利要求1所述特征的泵机组实现。优选的实施方式由从属权利要求、下面的说明和附图给出。
根据本发明的泵机组以公知的方式具有电驱动电机,该驱动电机设置在定子壳体中。在定子壳体中设置带有电线圈的定子。转子在定子内旋转,转子通过轴或以其他合适的方式抗扭地与泵机组的至少一个叶轮相连接。此外,为了将驱动电机设计为湿运行电动机,可以在转子和定子之间设置缝管或隔离球冠。该电驱动电机还具有在外侧面上与定子壳体相连接的接线盒。在此可以将接线盒径向或轴向安装在定子壳体上。
根据本发明将接线盒设计为,在其内部具有至少一个分隔壁。该分隔壁将由接线盒外壁围成的接线盒的内部空间分成至少两个区域,即电子区域和连接区域。在电子区域中设置通常设置在这样的接线盒中的电气和电子元件。这些电气和电子元件尤其可以是用于电机控制的电子元件,例如变频器的部件,或者用于调整驱动电机的电压。在连接区域中设置用于连接接线盒的电接头。在此,在连接区域中一方面设置用于至少一个连接导线(例如电源线)的电接头。但是另一方面,根据本发明在同一连接区域中还存在用于与设置在定子壳体内部的电气或电子元件电连接的触点。这些电气或电子元件例如是定子线圈或其他位于定子壳体内部的电气或电子组件。也就是说,在连接区域中还设置有用于连接接线盒与定子壳体内部的定子的电接头。这样做的优点在于,可以将接线盒所具有的两个主要的电接头,即用于供电连接导线的接头和用于连接定子的接头,安装在接线盒的与其他电子元件分开的共有的连接区域中。这简化了对接线盒的密封,因为只需要对该连接区域进行对外密封。在此不需要其他必须利用可拆卸的盖进行封闭的连接区域,如其在已知的用于将接线盒与连接导线电连接的布置当中那样。
理想情况下,分隔壁在接线盒的剩余区域中构成封闭的电子区域,从而即使为了使连接导线与设置在那里的电接头相连接而必须打开连接区域,也能够使其他的电子元件在该电子区域的内部得到保护。
特别优选该连接区域面向定子。这是非常有利的,因为如前所述在连接区域中还设有用于与设置在定子壳体内的电子和/或电气组件电连接的触点。通过这种方式可以使这些触点直接与对应的定子壳体上的触点或接头相接合。
进一步优选将该连接区域构造为朝向定子壳体是开放的,并通过相邻的定子壳体或封闭定子壳体的盖加以封闭。这样做的优点在于可以很容易地打开连接区域并将接线盒从定子壳体上移走。接线盒中的连接区域从通常面向定子壳体的一侧是容易接近的,因此可以在那里连接连接导线。通过将接线盒安装在定子壳体上,接线盒的连接区域将对外封闭。为此,可以进一步优选在接线盒和定子壳体或封闭定子壳体的盖之间设置密封件,用于对外密封连接区域,由此使得湿气不会从外部渗入该区域中并进而渗入接线盒内部或定子壳体中。
特别优选将接线盒安装在定子壳体的轴向端面上。在此,接线盒可以具有与定子壳体的外形相符的外部形状,从而可以在定子壳体和接线盒之间实现平稳过渡。优选将定子壳体设计为具有圆形横截面的管状。接线盒同样可以被设计为相应的圆形并具有与定子壳体的轴向端部相同的直径,由此使接线盒可以齐平地连接在定子壳体的轴向端部上。圆形形状的优点在于,定子壳体和接线盒之间的接触面可以非常简单地通过周向密封件加以密封。该密封件可以被构造为O形环,或者例如也可以通过注塑被模制在接线盒或定子壳体上。后者特别适用于定子壳体和/或接线盒由合成材料制成的情况。
优选将在连接区域中用于连接导线的电接头设计为连接端子或插接触点。这使连接导线能够理想地在不使用工具的情况下与电接头相接触。
优选使为此所要求的连接端子或插接触点延伸穿过分隔壁。即,连接端子或插接触点与电子区域内部的电气或电子元件导电连接。特别优选将连接端子或插接触点直接设置在位于电子区域中的电路板上。连接端子或插接触点可以这样延伸穿过分隔壁:使连接端子或插接触点的必须与连接导线压接的区域位于接线盒的连接区域中。所需要的用于断开和/或闭合连接端子的控制元件(例如杠杆)也优选位于连接区域中。由此可以在不打开电子区域的情况下使连接导线与连接端子或插接触点相连接。同时还可以通过连接端子在电子区域中建立电连接。此外,连接端子或插接触点的设置非常简单,因为它们可以与其他的电气和电子元件一起被放置在设置于电子区域中的电路板上。为了能够使连接端子或插接触点延伸穿过分隔壁,分隔壁可以具有开口。在所述开口的区域中,还可以根据需要设置密封件。替代地也可以将连接端子或插接触点直接设置在分隔壁上,然后使分隔壁在其面对电子区域的一侧固定在设置于那里的电路板上。由此可以减少所需元件的数量。
优选用于连接连接导线的连接端子具有用于打开该端子的杠杆。为了打开端子,优选使杠杆相对于弹簧预张力打开,从而释放端子的连接开口,连接导线的电导体插入该连接开口中。当杠杆被放松时,优选利用弹力使杠杆再次返回其初始位置,并在内部夹住连接电缆的导体。优选将杠杆设置为,使其可以为了打开而朝向位于连接空间的壁中的电缆穿管运动。在此,优选使连接端子面对电缆穿管设置,从而使电缆导体插入其中的开口与电缆穿管相对。然后,为了使端子张开必须沿电缆穿管的方向推压杠杆,这样做的优势在于,可以使杠杆与接线盒手动接合并可以在电缆上移动。在此可以非常简单地使杠杆保持打开状态。
进一步优选将用于与定子壳体内部的电气或电子元件电连接的触点设计为插接触点,其与定子或定子壳体上的对应的插接触点接合。由此能够非常简单地将接线盒装在定子壳体上,在此,这些插接触点在接线盒和定子壳体之间彼此导电接合。这特别有利于为了连接连接导线而必须将接线盒从定子壳体上移走的情况,因为由此可以容易地分开该连接并使其再次接合。
相宜地,连接区域毗邻接线盒的设有至少一个电缆穿管的外壁。在此优选该外壁为背对定子壳体的外壁。如果接线盒安装在定子壳体的轴向端部上,则可以将接线盒构造为罐状的,在此,接线盒通过其开放的一侧安装在定子壳体的端面上。优选将电缆穿管设置在接线盒的周壁上。因此,优选使连接区域与面对定子壳体的、开放的侧面和具有电缆穿管的周壁相毗邻。
电缆穿管可以公知的方式具有用于连接电缆的密封件和/或耐拉连接件(Zugentlastung)。
在连接区域中,除了以上所述的电接头之外还可以设置操作元件。例如,可以在那里设置用于调节驱动电机转速的调节元件。在此可以将这种调节元件设计为,其可以通过连接区域实现操作或调节并延伸穿过分隔壁进入电子区域中,在电子区域中设置有相应的将调节运动转化为电气参数的电气或电子组件。例如,在此可以设置电位计,其可以借助于设置在连接区域中的调节螺栓转动。为此可以使调节螺栓或轴延伸穿过分隔壁。
根据另一种优选的实施方式,分隔壁至少在一部分中相对于接线盒的外侧面、尤其是端面倾斜伸展。通过这种方式可以使连接区域在电缆穿管通入的区域中的高度大于其他的区域。由于优选将电缆穿管设置在接线盒的侧壁或周壁上,因此,连接区域在电缆穿管所处的区域中可能需要更大的高度或深度。
如上所述,优选将接线盒设计为罐状的并且一侧是开放的,该侧通过定子壳体或封闭定子壳体的盖来封闭。为此,将接线盒以开放的一侧安装在定子壳体上,优选安装在定子壳体的轴向端面上。在接线盒的开口的外周上可以设置密封件或密封面,设置在定子壳体上的密封件为了密封而贴靠在该密封面上。在这种罐状设计中,优选分隔壁相对于罐的开放的端侧倾斜伸展。通过这种方式可以提供一连接区域,该区域在优选设置在罐的周壁上的电缆穿管所在的一侧具有较大的轴向高度,从而可以将电缆从该侧插入连接区域中。在此进一步优选使倾斜的分隔壁与电缆穿管面对面,由此使得从外面插入电缆穿管中的电缆从倾斜的分隔壁有利地沿分隔壁的方向转向,从而使电缆能够很容易地被接线盒的开口抓住并插入到连接端子中。
优选分隔壁是安装在接线盒中的独立部件,其优选通过锁定连接件与接线盒的壁连接。这使得接线盒的生产与安装变得简单。因此,可以首先将电子元件设置在电子区域中或分隔壁上,然后将分隔壁安装在接线盒中,从而使电子区域被封闭并与连接区域分开。必要时可以在分隔壁与毗邻的接线盒壁之间设置密封件,以密封电子区域。通过锁定连接件的连接使得安装非常简单。
根据本发明的一种特殊的实施方式,分隔壁承载着至少一个设置在电子空间中的电路板。由此可以进一步简化安装,因为电路板可以在安装分隔壁之前固定在分隔壁上,然后与分隔壁一起安装在接线盒中。由此将省去在接线盒内部对电路板的单独固定和安装。另外,还可以在分隔壁上设置接头,尤其是用于与定子壳体内的电气或电子元件相连接的连接插件。然后可以将该电接头直接与位于分隔壁另一侧的电路板相连接。特别优选该电路板可以与构成插接触点的部分一起延伸穿过分隔壁中的开口。该部分优选是电路板的侧边缘或端面边缘,在此,在该端面边缘或侧边缘上,在电路板的一个或两个相对的表面上毗邻地设置电气触点,这些触点与定子壳体上的连接插件相接触。
如上所述,优选泵机组是循环泵机组,尤其是供热循环泵机组或非饮用水循环泵机组。优选驱动电机可以是具有隔离球冠的缝管电机(Spaltrohrmotor)或球形电机。在这种缝管电机中,在定子和转子之间设置将定子空间与转子空间分开的缝管。在本发明的思想中,将缝管理解为适用于分开转子空间和定子空间的各种元件,而与其形状无关。因此也可以将缝管构造为片状的或球冠状的。
附图说明
下面参照附图对本发明做示例性的说明。其中:
图1示出了根据本发明的泵机组的局部分解截面图,
图2示出了如图1所示的泵机组的接线盒的截面图,
图3示出了根据一种可选实施方式的接线盒的截面。
具体实施方式
图1中的泵机组以公知的方式具有定子壳体2,该定子壳体基本上为管状的,并且在其内部设有具有常规铁件和定子线圈的定子4。定子4环绕着隔离球冠或缝管6,而缝管6同时包围定子壳体2的轴向端部,其中,缝管6向外弯曲并围绕定子壳体2的轴向端面卷边。转子8可转动地支承在缝管6的内部。在此所示出的实施方式中涉及球形电机,其中,转子8被设计为半球形的,而隔离球冠形式的缝管6被构造为相应的半球形或球冠状。在转子8中一体化地设置叶轮10。叶轮10被装入在此未示出的泵壳体中。定子壳体2通过盖形螺母12与泵壳体连接。在定子壳体2上设有罐状的接线盒14。在这里所示出的实施例中,定子壳体2在其轴侧附加地由盖16封闭。但是需要指出的是,定子壳体2也可以直接通过接线盒14封闭。接线盒的外径基本上等于定子壳体2或其被覆物的外径。因此,总体上该泵机组基本为圆柱形的。
此外,在定子壳体2的内部设置电路板18,其与定子4的线圈电接触并在需要时承载例如电机控制装置的电子或电气组件。电路板18设有连接插件20,其穿过盖16。连接插件20用于与接线盒14内部的电气和电子组件相接触。
在图2中以单一视图示出的泵机组的接线盒14具有罐状外壁,其由环形周壁22和横向延伸的底部24构成。周壁22围绕纵轴或转动轴X延伸,底部24在此基本上在周壁22的轴向端部上横向延伸。优选周壁22和底部24由合成材料一体化地制成。在与底部24相对的轴向端部26上开放地设置接线盒14。当该开放的轴向端部26与接线盒14相连接时,该轴向端部被定子壳体2封闭。为此在定子壳体上配置周边密封件28,其在轴向端部26的区域中密封地贴靠在周壁22的内周上。
在接线盒14的内部设置分隔壁30。该分隔壁将接线盒4的内部空间分成两个区域,电子区域32和连接区域34。在此,分隔壁30包括两个部分30a和30b。部分30a基本上平行于底部24,即垂直于纵轴X延伸至开放端部26的附近。部分30b从部分30a开始相对于周壁22成角度地并朝向底部24延伸。在分隔壁30的部分30a延伸的区域中,连接区域34沿纵轴X的方向只有很小的轴向高度,该轴向高度在分隔壁30的部分30b倾斜延伸的区域中逐渐增大直至对面的周壁22。在该周壁上设置有电缆穿管36,连接电缆可以通过该电缆穿管被引入到接线盒14内部的连接区域34中。电缆穿管36与分隔壁30的倾斜部分30b相对置。
在电子区域32中设置电路板38,其承载着用于电动机的控制和/或供电的电子元件。这些电子元件40例如包括变压器。电路板38垂直于底部24并基本上平行于纵轴X延伸,并通过开口42插在分隔壁30上。电路板38通过这种方式固定在分隔壁30上。电路板38的部段44延伸穿过开口42并伸入连接区域34中,该部段44构成插接触点或插接区域。为此,在电路板的表面上临近电路板的端面边缘设置电触点,当将接线盒14安装在定子壳体2上时,该电触点可以与连接插件20中的电触点相接合。然后,电路板38的部段44电接触地插入连接插件20中。通过这种方式可以在接线盒14的电子区域32中的电子和电气元件与定子壳体2内部的电气和电子元件之间建立电连接。特别是将定子壳体2内部的电气或电子元件设置在电路板18上,或者通过电路板18实现电接触,例如线圈。因此,用于连接接线盒与定子内部的电气和电子元件的连接件由电路板38的部段44构成,其位于连接区域34内。
此外,在电路板38上设置连接端子46,其穿过开口包夹(durchgreift)在分隔壁30上,使得连接端子46的部分46a(在其中设置有用于插入连接电缆导体的开口)位于连接区域34中或朝向连接区域34开放,从而可以使连接电缆的导体在连接区域34中被插入连接端子46中。此外,连接端子46还具有杠杆48,用于控制连接端子46的打开。为此,在该实施方式中,为了打开连接端子46,杠杆48必须沿朝向电缆穿管36的方向运动,也就是沿图2中箭头A的方向运动。这样做的优点在于,一方面可以使接线盒14与杠杆48接合,另一方面可以将连接电缆从另一侧插入到接线盒中,从而能够使电缆简单地连接在连接端子46上。
需要指出的是,无论是连接端子46或其具有用于插入电缆的开口的部分46a,还是由电路板38的部段44构成的、用于连接定子壳体2内部的电子部件的插接区域,都在接线盒14的内部位于相同的连接区域34中。其优点在于,接线盒14只需要具有一个必须被密封的开口。为了连接连接导线,可以将接线盒14从定子壳体2上简单地移走,然后可以进入连接区域34。
为了进行安装,首先将分隔壁30与电路板18连接,即,电路板18以其部段44穿过开口42。随后将分隔壁30插入接线盒14中,并在那里通过锁定元件49定位在周壁22上。由此能够使分隔壁30与电路板18一起简单地安装在接线盒14的内部。
此外,在连接区域34中还设置有调节螺栓50形式的调节元件,可用以调节电机转速。调节螺栓50与延伸穿过分隔壁30的部分30a的轴52相连接,轴52控制设置在电路板38上的电位计54。
图3示出了接线盒14的一种可选的实施方式,其与前面所述实施方式的不同之处在于,在底部24'中附加地设置操作元件56和显示元件58。此外,在毗邻电子区域32的周壁22中还设有附加的连接插件60,用以连接传感器元件。
