Description
Der Gegenstand der Erfindung bezieht sich ausschließlich auf Scheibenradturbinen und besteht darin, daß die zwischen den einzelnen Laufrädern liegenden Leitscheiben oder Zwischenböden in ein oder mehrere mit dem. Turbinenzylinrfer zusammengegossene oder fest verbundene und allseits vom Treibmittel umspülte und geheizte besondere Tragzylinder ohne Spielraum vollkommen dampfdicht eingepaßt sind.The subject matter of the invention relates exclusively to disc wheel turbines and consists in the fact that the guide disks or intermediate floors located between the individual running wheels in one or more with the. Turbine cylinders cast together or solid special supporting cylinders connected and heated on all sides by the propellant are fitted completely vapor-tight without any clearance.
Die Abb. i: und 2 der Zeichnung veranschaulichen den Gegenstand gemäß der Erfindung an zweil Ausführungsbeispielen in Längsschnitten bei einer Hochdruckdampfturbine. Figs. I: and 2 of the drawing illustrate the subject matter according to the invention on two exemplary embodiments in Longitudinal sections of a high pressure steam turbine.
Beim ersten Ausführungsbeispiel (A]bb. 1) ist g1 das Turbinengehäuse, dessen äußerer Zylinder ζ der hohen Beanspruchung entsprechend fest ausgebildet ist, innerhalb dessen einIn the first exemplary embodiment (A] fig. 1), g 1 is the turbine housing, the outer cylinder ζ of which is designed to be solid in accordance with the high stress, inside it
ao mit dem Gehäuse g zusammengegossener besonderer Tragzylinder t für den Einbau der Leitscheiben oder Zwischenböden I sich befindet. Die Leitscheiben oder Zwischenböden Z sind in dem Tragzylinder t vollkommen dampfdicht und ohne Spiel eingepaßt. Die !Ausbildung des Tragzylinders t ist eine derartige, daß er etwas federt. Da außerdem der Tragzylinder t allseits vom· Treibmittel uirtspült und geheizt wird- und er vollkommene Dehnungsund Bewegungsfreiheit besitzt, ist schädlichen !Wärmedehnungen und Beanspruchungen auch bei hoher Überhitzung des Treibmittels vorgebeugt und sind auch die schädlichen Wärmebeeinflussungen von1 dem Zylinder ζ ferngehalten, wodurch dieser besonders für hohe Treibmitteldrücke geeignet wird.ao with the housing g cast together special support cylinder t for the installation of the guide disks or intermediate floors I is located. The guide disks or intermediate floors Z are fitted in the support cylinder t completely steam-tight and without play. The! Training of the support cylinder t is such that it is somewhat resilient. In addition, since the supporting cylinder t universally uirtspült by · propellant and wird- heated and it has perfect Dehnungsund freedom of movement, so it is harmful! Thermal expansions and stresses prevented even at high overheating of the propellant and also the harmful heat interference of one cylinder ζ kept, especially is suitable for high propellant pressures.
Vorteilhaft bestehen die Leitkanäle in den Leitscheiben I aus gefrästen und radial aneinandergereihten Einzelschaufeln e, welche einerseits mit den LeitscheibenI fest verbunden und andererseits in dem Tragzylinder t vollkommen dampf dicht, aber jederzeit lösbar eingebaut sind. Es findet dadurch eine Vereinigung der Vorteile der sehr genau herzustellenden gefrästen Einzelschaufeln mit den Vorteilen der aus einem Stück hergestellten Leitscheiben statt, wobei die Zahl der Befestigungselemente eine geringe ist. Außerdem wird durch die Einrichtung gemäß der Erfindung auch die Herstellung und der Zusammenbau vereinfacht.Advantageously, the guide channels in the guide disks I consist of milled and radially lined up individual blades e, which on the one hand are firmly connected to the guide disks I and on the other hand are completely vapor-tight but detachably built into the support cylinder t at any time. As a result, the advantages of the milled individual blades, which are to be produced very precisely, are combined with the advantages of the guide disks produced from one piece, the number of fastening elements being low. In addition, the device according to the invention also simplifies manufacture and assembly.
