具有用于叶片的滑动支承和枢转支承的旋转滑动叶片机器
本发明涉及一种用于流体处理的旋转滑动叶片机器(rotary sliding machine)，包括：壳体，其具有形成空腔的圆柱形内壁，该空腔具有用于工艺流体(process fluid)的入口和出口；转子，所述转子能够绕所述腔的偏心转子轴线沿旋转方向旋转，所述转子的外表面与所述壳体的内壁之间的距离沿所述旋转方向变化；叶片，所述叶片能够绕所述空腔的中心轴线旋转，所述叶片穿过所述转子中的向外指向的槽延伸到所述壳体的内壁，在旋转期间，在所述叶片和所述转子之间存在相对运动。
在所述叶片、转子的外表面和壳体的内壁之间限定了封闭空间。由于转子的外表面和所述壁之间的距离在旋转方向上变化，所以封闭空间的容积也在旋转方向上变化。在操作期间，这些空间填充有过程流体。入口和出口的位置和形状适于提供从入口到出口的工艺流体流。
空腔的端部通过端盖封闭，并且转子和叶片在轴向方向上延伸贯穿空腔。根据旋转滑动叶片机器的实际使用的要求，可在叶片的外边缘、叶片的侧部和转子的侧部设置密封件。
转子可由外部驱动器驱动。然后，转子驱动叶片，并且叶片使工艺流体移动。在这种情况下，如果工艺流体是液体，则旋转叶片机器用作泵，并且如果工艺流体是气体或2相(即液体和气体的混合物)，则旋转叶片机器用作压缩机。在其它使用中，工艺流体可驱动叶片，从而驱动转子，转子可做外功。在这种情况下，如果工艺流体是液体，则旋转叶片机器用作液压马达，并且如果工艺流体是气体或2相，则旋转叶片机器用作膨胀机。
US3130673A描述了一种旋转叶片泵，其中叶片在其槽中自由滑动，从而在旋转期间由于离心力而靠在转子的内壁上。此外，泵中的压力作用在叶片的内侧上，并迫使它们抵靠内壁。
GB190621345A描述了一种具有壳体和两个叶片的旋转叶片泵，该壳体具有圆柱形空腔，该两个叶片可围绕位于空腔中心的心轴独立地旋转。叶片具有等于腔的内半径的长度。具有圆柱形壁的从动转子偏心地位于壳体中，心轴定位在壁内。叶片在两个直径上相对的开口中穿过转子的壁。在旋转过程中，转子驱动叶片围绕心轴旋转。心轴和用于驱动转子的轴从相对侧延伸到空腔中。这样，在旋转期间，心轴不与转子干涉，并且轴不与叶片干涉。
WO9943926A1描述了一种旋转活塞机器，其包括具有空腔的壳体、容纳在壳体中的转子(该转子具有旋转轴线和外周表面)、与所述空腔连通的入口和出口通道、径向可滑动地容纳在转子的槽中的一个或多个叶片，每个叶片从壳体的内表面径向延伸到转子轴线、以及至少一个工作室，其为空腔的一部分并且由壳体的内表面、转子的外周表面和至少一个叶片的侧表面限定。每个叶片绕轴线铰接地连接到控制臂的一端，并且在另一端可枢转地轴颈连接在固定的轴杆中，该轴杆具有与居中地延伸穿过壳体的腔的轴线重合的中心轴线，该轴线与转子轴线平行地延伸并且与转子轴线间隔开，并且转子本身构成用于动力输出或动力输入的单元。
US3130673A因此描述了一种具有自由滑动叶片的旋转滑动叶片机器，而GB190621345A和WO9943926A1描述了一种具有导向叶片的旋转滑动叶片机器。对于高性能的旋转滑动叶片机器而言，导向叶片优于自由滑动叶片，因为导向叶片更容易在叶片之间提供密封，而不会使叶片过度磨损。GB190621345A的旋转滑动叶片机器是低压机器，其不适合高性能。WO9943926A1的旋转滑动叶片机器适于高性能。在这种机器中，叶片的枢转和滑动均被引导。然而，更紧凑和更不复杂的设计将是优选的。
对于所有的旋转滑动叶片机器，压力从入口到出口变化。因此，在叶片上存在变化的压差，这导致作用在叶片上的变化的切向力。通常，在旋转期间还存在切向力的方向的改变。
作用在每个叶片上的切向力在叶片中产生弯矩。切向力和弯矩被作用在槽中的叶片上的力吸收。切向力和弯矩也使叶片在其槽中倾斜。由于切向力在旋转期间改变方向，所以叶片在其槽中来回倾斜。还存在由惯性力引起的动态力，其作用在叶片上。
槽中的力在叶片在槽中滑动期间增加摩擦，这可减少滑动并增加叶片的磨损。一种减小摩擦的方法是使用滑动支承。滑动支承可以是干式、固态润滑的、由液体润滑剂润滑的或由工艺流体润滑的。
润滑槽中的叶片的一种方法是使用流体动力支承(hydrodynamic bearing)，即具有支承垫的支承，其中通过叶片的运动在垫和叶片之间形成润滑剂膜。然而，叶片运动方向的连续变化将阻止形成足够厚的润滑剂膜，因此流体动力支承并不总是适合的。
在许多服务中，为了不污染工艺流体，除了液体的工艺流体之外的润滑剂可能是不期望的。实例包括在工业过程中使用旋转滑动叶片机器作为发电中的蒸汽膨胀机或作为热泵中的压缩机。
本发明的目的是提供一种具有紧凑设计的带有导向叶片的高性能旋转滑动叶片机器。本发明的另一个目的是提供一种具有润滑叶片的旋转滑动叶片机器，其中所述设计在组装和维护方面是有效和有利的。本发明的另一个目的是至少提供现有技术的替代方案。
本发明的其它特征、优点和目的以及它们是如何实现的，将从说明书、附图和权利要求书中显现出来。
因此，本发明涉及一种用于流体处理的旋转滑动叶片机器，包括：
-壳体，所述壳体具有形成空腔的圆柱形内壁，所述空腔具有用于过程流体的入口和出口；
-转子，所述转子能够围绕所述空腔的偏心转子轴线沿旋转方向旋转，所述转子的外表面与所述壳体的内壁之间的距离沿所述旋转方向变化；
-叶片，所述叶片能够围绕所述空腔的中心轴线旋转，所述叶片延伸穿过所述转子中的向外指向的槽到达所述壳体的内壁，在旋转期间，在所述叶片与所述转子之间存在相对运动。
根据本发明，转子包括转子主体和叶片支承装置(vane bearing apparatus)，每个叶片支承装置包括：
-滑动支承主体，所述滑动支承主体具有用于所述叶片的槽，在所述槽的每一侧上，所述滑动支承主体具有面向所述槽的平面，所述平面形成用于所述叶片的滑动支承；在所述槽的每一侧上，所述滑动支承主体还具有背离所述槽的圆柱形凸面，所述槽的相对侧上的所述圆柱形凸面具有平行于所述转子轴线的公共轴线；
-在所述槽的每一侧上，枢转支承垫附接到所述转子主体或与所述转子主体成一体，所述枢转支承垫具有面向所述滑动支承凸面的圆柱形凹面，形成用于所述叶片的枢转支承，其中所述滑动支承凸面的所述轴线形成枢转支承轴线；
-在所述槽的每侧上，第一支承流体供应管线位于第一支承流体供应和所述枢转支承凹面之间；以及
-在所述槽的每侧上，第二支承流体供应管线位于第二支承流体供应和所述滑动支承平面之间，用于将支承流体供应至所述滑动支承平面与所述叶片之间的支承流体膜。
在旋转滑动叶片机器的一个实施例中，在槽的每一侧上，所述滑动支承主体具有形成缸体的凹陷。柱塞容纳在所述缸体中，并且支承流体通过缸体供应到枢转支承，并且供应到连接到柱塞或与柱塞成一体的滑动支承垫。在操作期间，柱塞在缸体中移动，并且这提供了一种叶片支承装置，该叶片支承装置增加了支承流体压力并且适应于叶片。
叶片的数量取决于实际设计，并且通常在2和10之间。
所述叶片支承装置是所述转子的一部分。为了将所述叶片支承装置与所述转子的其余部分区分开，所述转子的其余部分被称为转子主体。
现在将参考附图描述本发明的实施例，其中：
图1是根据本发明的旋转滑动叶片机器的截面图；
图2是示出根据本发明的旋转滑动叶片机器的叶片支承装置的截面图；
图3是示出了图2的叶片支承装置的替代方案的截面图；
图4是示出了力冲击根据本发明的旋转滑动叶片机器中的叶片的横截面视图；
图5是更详细地示出图1的叶片支承装置的剖视图；以及
图6是根据本发明的旋转滑动叶片机器的叶片支承装置的透视剖视图。
图1是沿轴向方向观察的根据本发明的旋转滑动叶片机器1的截面图。壳体2具有内壁3，该内壁形成具有空腔轴线43的圆柱形的空腔4。入口通道6从用于工艺流体的入口5延伸到空腔4，出口通道8从空腔4延伸到用于工艺流体的出口7。静止的心轴10定位于空腔4的中心。六个叶片12通过凸缘104和未示出的螺栓刚性地连接到相应的心轴环103，该心轴环可围绕心轴10独立地旋转。通过这种布置，叶片12可围绕空腔轴线43独立地旋转。仅最前面的心轴环103可见。
圆柱形的转子9连接到未示出的轴颈轴，并且在空腔4中沿方向11围绕转子轴线42偏心旋转。转子9包括转子主体101和叶片支承装置102。叶片12从心轴10径向延伸，穿过叶片支承装置102中的径向槽13，到达壳体内壁3。叶片密封件107抵靠壁3密封。
由于转子9的偏心，转子9的外表面14和壳体2的内壁3之间的距离在旋转方向11上变化。在叶片12、壁3和转子外表面14之间形成空间15，并且由于外表面14和壁3之间的距离在旋转方向11上变化，空间15的容积也在旋转方向11上变化。在旋转滑动叶片机器的使用过程中，空间15填充有工艺流体。空间15的变化的容积确保了工艺流体从入口5到出口7的净流量(net flow)。在入口5处，空间15具有入口压力，而在出口7处，空间15具有出口压力。因此，空间15的压力围绕转子9变化。
由于转子9偏心地安装在空腔4中，因此在旋转期间在叶片12和转子9之间存在相对的角度和径向运动，即，如从图1的不同叶片12之间的比较可以理解，在旋转期间在叶片12和叶片支承装置102之间存在向内和向外的滑动以及来回的枢转。
图2是示出了转子主体101和与图1的顶部叶片支承装置102处于相同位置的叶片支承装置102的截面图，但是是在更简单的实施例中。
图2的叶片支承装置102包括具有左部105和右部105'的滑动支承主体。滑动支承主体105、105'是圆柱形的，具有沿其纵向延伸的槽13，该纵向平行于转子轴线42。叶片12在槽的整个长度上延伸穿过槽13。在两端(图2中未示出)，滑动支承主体105、105'延伸超过槽13。叶片支承装置包括定位于槽13的相对侧上的两个相同的半部。左侧和右侧的相应元件由相同的附图标记表示，右侧上的那些元件加了撇号。为了简化描述，将着重在左侧，并且在需要时将着重在右侧。
滑动支承主体105具有面向槽13的平面115，其形成叶片12的滑动支承，滑动支承主体105还具有背离槽13的圆柱形凸面116。滑动支承主体的两个圆柱形凸面116、116'具有平行于转子轴线42的公共轴线118。
图2的叶片支承装置102还包括通过夹具109附接到转子主体101的枢转支承垫106。可选择地，枢转支承垫106可与转子主体101成一体。枢转支承垫106具有面向滑动支承凸面116的圆柱形凹面117。两个枢转支承凹面117、117'围绕滑动支承凸面116、116'，并且它们一起形成用于叶片12的枢转支承，其中轴线118作为枢转支承轴线。
第一支承流体供应管线112从第一支承流体供给管线36延伸到转子主体101中的开口121，进一步通过枢转支承垫106中的开口122，延伸到枢转支承凹面117中的开口，用于在枢转支承凹面117和滑动支承凸面116之间供应支承流体。密封件114确保在转子主体101和枢转支承垫106之间没有支承流体的泄漏。
第二支承流体供应管线113从第二支承流体供给管线39延伸到滑动支承平面115，用于将支承流体供应到滑动支承平面115和叶片12之间的支承流体膜。
图3示出了图2的叶片支承装置的替代方案，其中第二支承流体供给管线39已被省略，并且第二支承流体供应管线113从枢转支承凹面117与滑动支承凸面116之间的入口125延伸，用于将支承流体供应至滑动支承平面115与叶片12之间的支承流体膜。
第一支承流体供给管线36(以及第二支承流体供给管线39(如果包括的话))沿转子9的轴向延伸，并且是将支承流体供给到静压支承的通道、孔或管的分支网络的一部分。支承流体从固定供应源供给，并在旋转期间经由固定和旋转部件以及它们之间的密封件而传递到转子。
图2和3还示出了叶片凸缘104和心轴环103之间通过螺栓108的连接。
在进一步描述叶片支承装置102之前，参照图4，该图是示出了作用在图2和3的叶片12上的力以及这些力如何被吸收的简化剖视图。参照图1，叶片12左侧的空间15'具有压力p1，叶片12右侧的空间15″具有高于压力p1的压力p2。因此，在叶片12上存在压差。该压差的力可以由切向合力R表示，其大小等于压差和叶片暴露于压差的面积的乘积。切向力R和由R产生的弯矩在槽13中被来自滑动支承主体105的反作用力F1和来自心轴10的较小的反作用力F2吸收。F1指向与R相反的方向，而F2指向与R相同的方向。F1被枢转支承垫106吸收为力F3并传递到转子主体101。
由于方程式：
F1＝F2+R
以及
F1＝F3
由于空间15’、15″内的压力在旋转期间变化，叶片12上的压力差也在旋转期间变化。另外，由于转子外表面14和壳体内壁3之间的距离在旋转期间变化，叶片12的暴露于压力差的面积也变化。因此切向力R在旋转期间变化。通常，压力差在旋转期间改变方向，因此切向力R也改变方向。当切向力R改变且改变方向时，力F1、F2和F3也改变和改变方向。除了由于压力差产生的力之外，还有由振动、向心加速度、科里奥利力(Coriolis force)和其它惯性力产生的动态力，这些力对叶片12和滑动支承以及枢转支承之间的力有贡献。
进一步参照图2和3，在旋转滑动叶片机器的操作过程中，处于供应压力的支承流体从第一支承流体供给管线36通过第一支承流体供应管线112流到枢转支承凹面117，在该处，支承流体分布在枢转支承凹面117和滑动支承凸面116之间。在图2的叶片支承装置中，处于供给压力下的支承流体还从第二支承流体供给管线39通过第二支承流体供应管线113流到滑动支承平面115，在此处，支承流体分布在滑动支承平面115和叶片12之间，并形成滑动支承流体膜。在图3的替代性叶片支承装置中，其中没有第二支承流体供给管线，一些支承流体从枢转支承凹面117和滑动支承凸面116之间的区域流入入口125，通过第二支承流体供应管线113，到达滑动支承平面115，在此处，支承流体分布在滑动支承平面115和叶片12之间，并形成滑动支承流体膜。
在滑动支承中，在滑动支承平面115的边缘处，支承流体从支承流体膜泄漏到槽13中，并终止于空腔中的空间15'中，在该处，其与工艺流体混合。因此，滑动支承的压力以及因此支承力朝向其边缘减小。
在枢转支承中，图2和3示出了一个实施例，其中枢转支承密封件110在枢转支承凹面117处围绕第一支承流体供应管线112的端部。枢转支承密封件110具有使得非常少的支承流体从枢转支承泄漏到槽13中的效果。枢转支承密封件110、枢转支承凹面117和滑动支承凸面116限定压力室，在该压力室中，在由枢转支承密封件110限定的整个区域保持压力。该压力室提供了在枢转支承凹面117和滑动支承凸面116之间的液压力传递。
枢转支承密封件110可以省略，如果这样，则枢转支承凹面117和滑动支承凸面116之间的支承流体将形成如在正常静压支承中的膜，使得支承流体在其边缘处泄漏，并且压力朝向其边缘减小。
在槽13的每一侧上，转子主体101具有面对滑动支承凸面116的圆柱形转子主体凹面120。转子主体凹面120和枢转支承凹面117是邻接的，并且由转子主体密封件111分开。
已经发现，在旋转滑动叶片机器的操作期间，在叶片12在槽13中来回枢转期间，与叶片、滑动支承和枢转支承相关的力可作用在由枢转支承密封件110和转子主体密封件111限定的区域中。转子主体密封件111确保从枢转支承密封件110泄漏的支承流体至少在一定程度上保留在该区域中并且润滑该区域。此外，在极端条件下(例如由于意外的压力或振动)，力可能超出转子主体密封件111作用，并且滑动支承凸面116然后加载转子主体凹面120。转子主体凹面120因此形成用于静压枢转支承的支撑。
通常，作用在表面和流体之间的力等于流体中的压力和表面面积的乘积。然而，对于静压支承垫，支承流体膜压力在该区域上变化，并且在支承垫的边缘处最低。为了简化力的计算，假定支承流体膜中的恒定压力和支承垫的有效面积。有效面积通常为支承垫面积的60-80％。
参考图4和以上力的讨论，来自滑动支承主体105(即滑动支承平面115)的力F1等于来自枢转支承衬垫106的力F3。已经发现，为了确保叶片支承装置102的平滑操作，滑动支承平面115的有效面积与由枢转支承密封件110限定的面积之间的差应当最大为25％。
图5是更详细地示出根据本发明的另一叶片支承装置的剖视图，该叶片支承装置对应于用于图1的顶部叶片12的叶片支承装置102。图5的叶片支承装置102与图2和3的叶片支承装置102具有许多相似性，并且仅在需要理解图5时才描述相似的项目。
槽13两侧的元件是相同的。在左侧和右侧的相应元件由相同的附图标记表示，其中右侧上的元件加了撇号。槽13两侧的元件将仅在需要时描述。
滑动支承主体105具有形成缸体(cylinder)21的凹陷，该缸体21具有底部23和朝向槽13的开口22。第二支承流体供应管线113由滑动支承主体105中的孔形成，该孔从滑动支承凸面116中的入口125延伸到缸体21。具有底部31的柱塞29容纳在缸体21中，O形环35密封在柱塞29和缸体21之间。滑动支承垫27与柱塞29形成一体并容纳在缸体21的扩大部分44中，滑动支承垫27具有凹部28和形成滑动支承平面的表面115。可选择地，滑动支承垫27和柱塞29可以是单独的部件，并例如通过螺纹机械连接。凹部28有利于将支承流体分配到滑动支承垫平面115和叶片12之间的滑动支承流体膜中。因此凹部28是优选的，但也可以省去。支承流体通道32在柱塞底部31中的开口33和滑动支承垫凹部28之间延伸。可选择地，如果省去凹部28，则支承流体通道32的开口可以位于滑动支承垫平面115中。
可更换的插入件48'以螺纹连接38'拧入柱塞29'中。插入件48'提供支承流体通道32'，并且具有由支承流体通道32'的收缩部形成的流动限流器34'。插入件48'还具有与合适的键(例如六角键)匹配的内螺旋驱动器(internal screw drive)40'，以便能够插入和移除。插入件48'可以制成具有不同的流动限流器，以适应不同的操作条件。
枢转支承衬垫106在其凹面117中具有凹部119，该凹部119被枢转支承密封件110包围。凹部119便于支承流体在枢转支承凹面117和滑动支承凸面116之间的分配。因此，凹部119是优选的，但也可以省去。
仍然参照图5，在旋转过程中，工艺流体的压力变化引起叶片12上的变化的切向力，如参照图4所讨论的。这些切向力使叶片12在槽13中朝向和远离滑动支承垫27、27'稍微地来回倾斜。当叶片12朝左滑动支承垫27倾斜时，这增加了左滑动支承流体膜中的压力，这继而迫使左滑动支承垫27和左柱塞29朝左缸体底部23移动。这增加了左缸体21中的支承流体压力，并且该压力增加传递到由枢转支承密封件110、枢转支承凹面117和滑动支承凸面116限定的左压力室。左第一支承流体供应管线112具有由收缩部形成的流动限流器25，这限制了支承流体返回到左第一支承流体供给管线36，这维持了由枢转支承密封件110、枢转支承凹面117和滑动支承凸面116以及左缸体21限定的左压力室中的支承流体压力。由此具有增加的压力的支承流体从左缸体21通过左支承流体通道32流到左滑动支承衬垫平面115中的凹部28，并流到左滑动支承流体膜。这从左缸体21中移除流体，并且因此滑动支承流体膜将左滑动支承垫27进一步推向左缸体21，并且将左柱塞29进一步推入左缸体21中。这持续到叶片12以另一方式倾斜为止。
同时，叶片12倾斜远离右滑动支承垫27'，这降低了右滑动支承流体膜中的压力。该压力降低通过右支承流体通道32'传递到右缸体21'，并且进一步传递到由枢转支承密封件110'、枢转支承凹面117'和滑动支承凸面116'限定的右压力室。该减小的压力使得处于供给压力的支承流体从右第一支承流体供应管线112'流到右枢转支承凹面117'中的凹部119'，并且进一步通过右第二支承流体供给管线113'流到右缸体21'。右缸体21'中的支承流体迫使右柱塞29'和右支承垫27'向外朝向叶片12。同时，由于右滑动支承流体膜的压力降低，支承流体从右缸体21'通过右支承流体通道32'流到右滑动支承垫平面115'中的凹部28'并流到右滑动支承流体膜。这降低了右缸体21'中的压力，因此处于供给压力的更多支承流体从右第二支承流体供应管线113'和右第一支承流体供应管线112'进入右缸体21'。这种情况持续到叶片12以另一方式倾斜。
因此，当叶片12向左推动左支承垫27时，右支承垫27'也向左朝向叶片12移动，反之亦然。这样，支承垫27、27'的位置适应于叶片12的位置，并且同时保持允许叶片12滑动的支承流体膜。一个特别的优点是，支承垫27、27'使它们的位置适应于形成静压支承、叶片和槽的零件的生产偏差和热变形。
凹部28和119形成支承流体贮存器，其使叶片支承装置102的各个部件的运动平滑。
支承流体通道32的限流器34和第一支承流体供应管线112的限流器25减缓支承流体的流动并减少支承流体压力的传递。所示的收缩部是流动减速器的示例，但是可以使用任何类型的流动减速器。所述限流器可以是不同的限流器，但也可以由流体管线本身形成，其是流体管线的直径、形状和长度的函数。限流部25可以替代地是止回阀。
在一些操作条件下，槽13的相对侧上的滑动支承垫27、27'被叶片12不均匀地加载。已经发现，在这样的操作条件下，优选的是，在槽13的最大加载侧上的第一支承流体供应管线112、112'的限流器25、25'包括止回阀，而在槽13的最小加载侧上的限流器25、25'不包括止回阀。
已经发现，为了确保力通过柱塞29和滑动支承垫27的有利传递，优选地，柱塞底部31的面积应当小于滑动支承垫27的有效面积。还已经发现，为了确保力通过柱塞29和枢转支承垫106的有利传递，优选地，柱塞底部31的面积和由枢转支承密封件110限定的面积之间的差应当最大为25％。
通常，转速为500-3600rpm。工艺流体压力通常为1-16巴。支承流体供给压力必须高于工艺流体压力，并且通常为10-40巴。
图6是根据本发明的旋转滑动叶片机器的叶片支承装置的一个实施例的透视剖视图。壳体和转子主体的大部分已经被移除。叶片12设置在具有凸面116的滑动支承主体105的槽13中。滑动支承主体105的端部延伸超过槽13和叶片12，并且由端部枢转支承123支撑。端部枢转支承123由作为转子主体的一部分的腔体端盖124支撑。左端盖被移除，并且因此在图6中可见左端部枢转支承123。右端盖124就位，并且隐藏右端部枢转支承。
枢转支承垫已经被移除。通向第二支承流体供应管线的一排入口125布置在滑动支承凸面116中。
已经发现，转子主体101上的来自叶片12的载荷的至少80％可以通过叶片支承装置102传递，其余的通过端部枢转支承123传递。通过叶片支承装置传递的这大部分负载是非常有利的，因为其减小了端部枢转支承123的所需尺寸。此外，滑动支承主体105沿其长度的支撑减小了其偏转。
图6进一步示出了叶片密封件107、心轴10、叶片凸缘104以及它们通过螺栓108与心轴环103的连接。相邻的主轴环103'、103"'用于未示出的叶片。105'表示相邻的叶片支承装置的滑动支承主体，而107'表示用于其叶片的叶片密封件。
