Abstract
本发明的目的是创造一种使透平增压器的径流
式透平和相应的内燃机匹配的方法和装置，该方法和
装置用较少的材料消耗和工时及低的成本解决问
题。按照本发明，这一目的是通过仅修改径流式透平
(1)的燃气出口端部件来实现的。为此，转子(6)的叶
片首先缩短，然后相应使转子(6)的轮毂(8)和燃气出
口突缘(9)之间流道(7)相应收窄。这通过采用一个
不同的相应放大的燃气出口突缘(9)来实现。为此，
燃气出口突缘(9)固定在燃气进口壳(2)上，从而它能
迅速地拆卸。
Description
本发明涉及透平增压器径流透平和内燃机配合的方法和装置。
这种透平增压器的径流式透平是公知的，在燃气进口端，基本上包括一螺旋形燃气进口壳和一个在空间上沿燃气出口端方向限定所述壳的喷咀环。被支承在压气机驱动轴上并设有叶片的转子配置在燃气出口端。燃气流道在转子轮毂和燃气出口壳相反区域之间延伸。利用一个用若干均布于周边的螺栓可拆卸地连接于燃气进口壳上的燃气出口突缘来代替燃气出口壳也是公知的。
若透平增压器要和某一内燃机相联，则该径流式透平的临界流量，即由它产生的输送流量的大小对于一个给定的机器必须相应地匹配。
在这方面，已知一种方法，其中，首先通过自叶片高度上去除材料来缩短转子叶片和喷咀环叶片，使和内燃机的参数相适应。作为一个替代方案，如果需要，此外还可或必须修改喷咀环叶片的安装角，即采用具有所要求的叶片安装角的不同的喷咀环。由于燃气进口壳和喷咀环是相互精确匹配的，因而该燃气进口壳必须相应匹配，即它也须被更换。
在该方法中，径流式透平相应于修改的转子的匹配在燃气进口端进行，即喷咀环和螺旋形燃气进口壳均必须被更换。为此，该方法在其动力方面是极昂贵的，因而成本很高。由于有许多组合的可能性，就要求很多保存相应更换部件的库房和为透平增压器与相应内燃机匹配（在工地进行）的广泛的输送要求。
在透平增压器和内燃机匹配的特殊情况中，诸如在紧急发电装置中，需要一个迅速响应的透平增压器，通过采用轻质材料如陶磁的适当转子来减小转子的惯性矩。然而，这些公知的转子是非常昂贵的，此外，并不具有足够的工作可靠性。
因此，本发明的一个目的是要消除所有这些缺点，并提供一种新颖的方法和装置来使透平增压器的径流式透平跟特定的内燃机相匹配，该方法和装置仅需较小的材料消耗和工时，且成本低。
按照本发明，这是通过仅修改径流式透平的燃气出口端部件来实现的。若转子叶片首先被去短而后相应收窄转子轮毂和燃气出口突缘之间的流道是特别有利的。
在本发明的另一实施例中，首先插入一较小的转子，以使透平增压器的径流式透平跟内燃机匹配，然后相应收窄转子轮毂和燃气出口突缘之间的流道。
本发明的优点是修改的转子外形的匹配工作在燃气出口端进行，尤其是，不必更换前述的相互匹配的燃气进口端部件，即燃气进口壳和喷咀环。在这方面，有可能使这些部件的拆装、贮存和运输以及喷咀环附加的匹配要求和成本更经济。
用相应于去短的转子叶片放大的不同的燃气出口突缘来替代现有的燃气出口突缘以收窄流道是特别方便的。因此，按照本发明，只需贮存、运送和匹配一个大致较小尺寸的附加部件。
为了确保迅速拆装，如果燃气出口突缘以能迅速拆卸的方式固定在燃气进口壳上，则提供了另一个优点。为此，借助于一个卡紧带和至少一个沿圆周方向配置的螺栓使它们保持在一起。
最后，喷咀环以可靠和能迅速拆卸的方式有利地配置在燃气进口壳和燃气出口壳之间。因此，如果需要，它能较快地更换。这是首先通过松开螺栓和卡紧带自燃气出口壳上拆去燃气出口侧突缘来进行的。然后喷咀环能自燃气进口壳内的插入连接中抽出，并用一个不同的喷咀来代替。随后，按相反的顺序装配。按照本发明，如果需要，仅通过将燃气出口突缘易于可拆地固定在燃气进口壳上，便能得到喷咀环较方便和较迅速的更换的另一优点。
通过参照下列详细叙述，连同附图一起考虑时，随着本发明被清楚理解，将会很快地达到对本发明更完整的领会和获得许多伴随的优点，其中单张图表示了本发明的采用一径流式透平的实施例。
现在参照附图，该图表示经该径流式透平的纵剖视图，在下半部的燃气出口端部件表示相应于原始状况，而上半部中的这些表示按本发明修改的。
仅表示出对理解本发明所必需的构件。没有表示安装部件。没有表示的安装部件是，例如透平增压器的压气机组件及其烟筒紧固件。以箭头指示工质流动方向。
该径流式透平1在燃气进口端包括一螺线形燃气进口壳2，在空间上受喷咀3限定。一个设有叶片5的转子6配置在压气机驱动轴4的上燃气出口端处。燃气流道7由转子6的毂8及燃气出口突缘9构成，后者借助于沿圆周方向配置的卡紧带10和螺栓11又固定在燃气进口壳2上。压气机驱动轴4由壳13内的轴承12支承。喷咀环3以可靠和能迅速拆卸的方式设置在燃气进口壳2和燃气出口突缘9之间。
为了使径流式透平1和内燃机匹配，在转子6的叶片5被缩短之后，将流道7相应收窄。这是通过安装一个跟缩短的叶片5相匹配的燃气出口突缘9、即有放大轮廓的燃气出口突缘来实现的。这一更换能特别快地进行，因为燃气出口突缘9借助于卡紧带10和螺栓11能迅速可卸拆地固定在燃气进口壳2上。
由于喷咀环3可靠和能迅速拆卸地配置在燃气进口壳2和燃气出口突缘9之间，若需要该喷咀环3也能较快地更换。为此，首先，用卡紧带10和螺栓11将燃气出口突缘9自进口壳2上松开。然后，自连接件上取下喷咀环3，并换上一个不同的。再按相反的程序进行装配。
在本发明的另一实施例中，首先采用一较小的转子6，使透平增压器的径流式透平和内燃机适配，然后使流道7在转子6的轮毂8和燃气出口突缘9之间相应收窄。
显然，按照上述技术，本发明可以有许多修改和变化。因此，要理解除了这里具体叙述的之外，本发明可以在所附权利要求书的范围内实施。
