Description

压缩机节能器管子组件
技术领域
本发明总的涉及密封的压缩机,尤其涉及密封的压缩机中的一节能器(economizer)管子组件。
背景技术
一般的压缩机由几个包括压缩腔在内的舱所组成。压缩机的各个舱被一外壳所包围。压缩机的正常工作要求压缩机的各舱之间以及与环境之间保持密封。为了提高冷却循环的效率,许多压缩机采用节能器循环作为冷却循环的一部分。作为节能器循环的一部分,一部分制冷剂要通过节能器管子注射到压缩腔。
采用节能器管子必须不破坏压缩机的各密封舱的完整性。因此,在节能器管子与压缩机壳体之间必须有一制冷剂蒸气密封。此外,设计一节能器管子组件也是有利的,因为它有助于压缩机内的压缩腔相对于压缩机外壳对齐。
发明内容
总的来讲,本发明提供一管子组件,它不仅作为一使压缩腔相对于压缩机的外壳对齐的机械使用,而且还保持了压缩腔的整体性,并容易安装到压缩机的外壳上。
本发明的一较佳实施例包括一具有一壳组件和壳体构件的密封压缩机。节能器管子组件包括一连接于节能器配件延伸件的节能器配件。节能器配件和节能器配件延伸件都有一内腔,两内腔彼此连通。节能器配件固定于中心壳组件,节能器配件延伸件延伸进中心壳组件。节能器配件延伸件与压缩机的壳体构件形成制冷剂蒸气密封。在最佳实施例中,压缩机包括一涡旋式压缩机,壳体构件包括一非轨道运行蜗壳。
附图说明
根据以下对目前较佳实施例的详细描述,本发明的这些和其它特征以及优点对本领域的熟练技术人员而言将变得更显而易见。详细描述中用的附图描述如下:
图1是根据本发明设计的一压缩机的立体图;
图2是根据本发明设计的一节能器管子组件的侧视图;
图3是图2的端视图;
图4沿图3的线A-A截取的剖视图;以及
图5是采用节能器管子组件的压缩机的部分剖视图。
具体实施方式
压缩机在图1中总的用20表示。压缩机20总的包括一由一上壳组件24、中心壳组件26和下壳组件28组成的外壳组件22。上壳组件24包括一排放口配件30。中心壳组件26包括一节能器配件32、一吸入口配件34和一泄油口配件36。在后面的描述中,压缩机20将被描述为涡旋式压缩机,如本领域的熟练技术人员所知道的,压缩机20可包括任何其它已知的密封压缩机。
节能器管子组件在图2中总的用37表示。节能器管子组件37包括连接于节能器管子配件延伸件38的节能器管子配件32。节能器管子配件32包括一具有凸起段46和一凸缘48的外表面44。凸缘48包括一第一表面49。节能器配件延伸件38包括一具有一凸起段52、一槽54和一第一斜削端的外表面50。图3是图2所示的节能器组件37的端视图。
图4是沿图3的线A-A截取的剖视图。节能器配件32包括一内腔60。节能器配件延伸件38包括一与第一斜削端56相对的第二斜削端62。节能器配件延伸件38还包括一内腔64。内腔60与内腔64连通。
最好是,节能器配件32包括一在与节能器配件延伸件38相反的端部上的配件,这在本领域中是已知的。最好是,节能器配件延伸件38装配在内腔60的内侧,而且节能器配件延伸件38与节能器配件32之间的压配合使它们连接在一起。第二斜削端62有助于节能器配件延伸件38插入节能器配件32。当节能器配件延伸件38插入节能器配件32时,凸起段52紧贴第一表面49。在凸起段52与第一表面49之间形成一约90度的角。节能器配件32的凸起段46包括一组内螺纹、以连接到一压缩系统(未示出)的其它部件上,这也较好的。
图5是采用节能器管子组件37的压缩机20的局部剖视图。如上所述,压缩机20称为涡旋式压缩机,本领域的熟练技术人员应理解压缩机20还可包括任何其它密封压缩机。如图5所示,节能器配件延伸件38延伸进中心壳组件26。节能器配件延伸件还延伸进和连接于一壳体构件70。壳体构件70构成了压缩机腔的一部分。在图5中,由于压缩机20是一涡旋式压缩机,所以壳体构件70包括一非轨道运行的蜗壳(non-orbiting scroll)。壳体构件70包括一容纳节能器配件延伸件38的孔71。孔71的直径设计成在节能器配件延伸件38与孔71之间形成压配合。这种压配合使节能器配件延伸件38与壳体构件70之间形成制冷剂蒸气密封。
第一斜削端56有助于节能器配件延伸件38插入壳体构件70。当节能器配件延伸件38插入壳体构件70时,在节能器配件延伸件38与中心壳组件26之间出现间隙73。间隙73有助于压缩机20内的壳体构件70与节能器管子组件37的对齐。焊缝72和延伸件38处的可靠密封可允许有间隙73存在。
节能器配件32通过焊接连接72连接于中心壳组件26。第一表面49紧贴地安装于中心壳组件26。因而,焊接连接72使节能器管子组件37密封于中心壳组件26。
压缩机20还包括一分离器板组件74、一焊接环76和一排放口覆盖件78。压缩机20还包括一与内密封件82和外密封件84相邻的轨道运行蜗壳80。如上所述,当压缩机20是一涡旋式压缩机时,壳体构件70最好包括一非轨道运行蜗壳。在一密封压缩机而不是涡旋式压缩机中,壳体构件70可构成压缩机的压缩腔的一部分。
已根据有关的法定标准对本发明作了描述,因此,上述的描述实质上是示范性的,而不是用来限定本发明的。对上述实施例的改变和变异,对本领域的熟练技术人员而言是显而易见的,并落在本发明的范围之内。因此,本发明所提供的法定保护范围只能由以下的权利要求书来确定。
