Abstract

转轮(1)驱动侧棱边在与泵壳后壁(5)有少许间隙(a)情况下转动。泵壳后壁(5)与转轮(1)构成一使泵腔(2)与轮毂腔(7)连通的曲折间隙(6)。轮毂腔(7)中，有一与转轮(1)同转的叶轮，用以使液体在轮毂腔(7)中加速转动。轮毂腔(7)具有一外围开口(12)，轴(4)附近的气体通过轮毂壳壁(20)和轴(4)间的间隙(10)逸出。外围开口(12)通入一个与轮毂腔(7)通过间隙(10)相通的腔(11)中，对准一扩散管(13)，形成一个液体喷射唧筒(12、13)。

Description

离心泵
本发明涉及一种权利要求1的前序部分所述的离心泵。
譬如欧洲专利114932已描述了这种类型的离心泵。
本发明任务在于，在这种类型的泵中，对气体和液体的分离进行改进。
解决以上任务的技术方案在于权利要求1的特征部分所述特征构成的方案。
根据转轮的不同构形情况，在泵腔内部出现的超压状况也不一致，并且得出不同的液气组合状况。本发明的目的在于，相对于现有技术，在与转轮的构形无关的情况下对液体和气体的分离进行改进。
不转动地与转轮相连的同心叶轮的叶片或径向对称地固定在转轮轮毂上的叶片收集进入轮毂腔内的介质并使这些介质的转动得到加速，其结果是：气体与液体的分离变得更加明显，因为，气体可在最小直径处(在轴隙处)离开轮毂腔。气体在重新与液体混合和可通过曲折间隙中的不同压力情况回到转轮通道之前离开轮毂腔。分离出的液体有一个较高的压力并通过一个液体喷射唧筒的喷嘴被排出。通过液体喷射产生的负压被用于清除分离出的气体。出自液体喷射唧筒的气液混合物可被送入一个公知结构的气体分离器，液体由该气体分离机被送回泵的抽吸管道。
下面借助示意附图举例说明本发明，附图所示为：
图1是离心泵的断面图；
图2是离心泵的缩小前视图。
图1所示的离心泵具有一个敞开的、单浆叶转轮1并且可转动地装设在一个泵壳2内。离心泵的转轮1以其轮毂3座落在一个支承在轴承19上的轴4上并在与壳体后壁5有小间隙“a”的情况下转动。壳体后壁5与离心泵转轮1的轮毂3构成一个曲折间隙6。该曲折间隙使泵腔2′与一个轮毂腔7连通。待排送物料中的、聚集在转轮中心的并与液体混合的气体通过曲折间隙6由泵腔2′进入轮毂腔7。在轮毂腔7中，通过不转动地与轮毂3连接的叶片8使这些气液混合物加速转动。通过气液混合物的加速转动促进了气体和液体之间的分离。通过一个位于轮毂壳壁20内的螺旋槽9使或许出现的纤维与轴隙10隔离，气体可通过轴隙10进入一个通过轮毂壳壁20与轮毂腔7隔开的腔11中。同时，液体在较高的压力下通过了一个穿过轮毂壳壁20的反推喷嘴12由轮毂腔7流入一个扩散管13，并从腔11中带走气体。一个与扩散管13相接的连接管道14(参见图2)把气液混合物送入一个气体分离器15。该气体分离器15把液体送回至离心泵的吸入侧连接管道16，气体通过管道17被排入一个适宜的腔内。轴封18防止驱动件和支承件与待输送的物料接触。

2、按照权利要求1所述的离心泵，其特征在于，出自液体喷射唧筒(12、13)的液气混合物进入一个气体分离器(15)，液体通过一个连接管道(16)由气体分离器被送回到离心泵入口，而气体进入一个适于容纳气体的腔内。
3、按照权利要求1或2所述的离心泵，其特征在于，叶轮的叶片或固定在转轮轮毂(3)上的叶片有间距地处于一个导向螺旋(9)，特别是一个螺旋槽(9)或一个螺旋翅片的对面，以上导向螺旋(9)或螺旋槽(9)或螺旋翅片沿轴(4)的转动方向向外伸展并从而使固体与间隙(10)隔离。
