Description

Hydropneumatischer Druckspeicher Die Erfindung bezieht sich auf einen hydropneumatischen Druckspeicher von im wesentlichen zylindrischer Form, der in seinem Innern durch eine elastische, flexible Trennwand in einen Gas-und einen Flüssigkeitsraum unterteilt ist und mit Öffnungen zum Einfüllen von Gas und Flüssigkeit versehen ist.Hydropneumatic pressure accumulator The invention relates to a hydropneumatic pressure accumulator of substantially cylindrical shape, which is in its interior by an elastic, flexible partition into a gas and a liquid space is divided and provided with openings for filling gas and liquid is.

Druckspeicher dieser Art werden in der Technik vielseitig verwendet-Sie dienen hauptsächlich zum Speichern von Flüssigkeit unter Druck und in Verbindung mit Drosseln zum Dämpfen von Druckschwingungen oder -stüßen. Bisher geschah ihre Herstellung durch Tief- ziehen oder Schmieden eines zylindrischen Hohlkörpers, dessen freie Öffnung nach dem Einbringen der Trennwand durch aufgeschraubte oder eingeschweißte Deckel verschlossen wurde: Insbesondere bei langen zylindrischen Partien ist diese-Herstellungsmethode aber aufwendig und teuer, da für jede Baulänge eine spezielle form vorhanden sei-- mu,#g Zudem ist ein Tiefziehvorgang nur bei bestimmten Materialiep.: möc;:lich. Materialien höherer Festigkeit müßten geschmiedet werden. Es ist Aufgabe der Erfindung, die aufwendigen Tiefziehe bzgem Schmiadevorqänge zu umgehen und dennoch einen Druckspeicher mit beliebiger Längt, sauberer, glatter Oberfläche und ausreichender Festigkeit herzustellen. Die Lösung dieser Aufgabe erfolgt dadurch, daß die zylindrische Parte aus einem Stahlrohr besteht, dessen Enden durch Deckel verschlossen werden. In sT ^nstiger Ausführung der Erfindung izY d frinig und wird vor dem endgültigen VeschxiCca dan Stghlrohre durch ein Halteglied c:a@@a in dsr Rohrmitte befeotigü. bo Deckel kUnnen aufgezchraut oder angezahvieißt vyo-rden und hönen 5L0 Tiofzi'ah- oder. Schin.iede, teil hergeoboll t eyerünn - - Auch handelsübliche Klöpperböden können Verwendung finden. Der Vorteil der Erfindung liegt darin, dalß für verschiedene Druckspeichergrößen nunmehr allein die Membranform geändert werden muß. Für das Druckspeichergehäuse ist eine Form nicht mehr notwendig. Die Deckel können zwar noch geschmiedet sein, jedoch ist dies vergleichsweise einfach und billig, und. die Form ist-die gleiche, solange die Rohrdurchmesser gleich sind. Festigkeitsmäßig ergeben sich gegenüber einem Druckspeicher mit nur einem Deckel keine Nachteile, da die Beanspruchüngeh von zwei Deckeln gleich sind. Die Befestigungszonen, insbesondere beim Schweißen, der Deckel sind von der Stelle der Membranein- . Spannung entfernt, so daß die Membrane keine thermisch bedingten . Schäden erleiden kann. Als Rohr kann zudem gezogenes Material verwendet werden, welches bekanntermaßen eine gute Oberfläche aufweist. Da die Membran beim Betrieb gegenüber dem Gehäuse auch mindestens kleine tangential gerichtete Bewegungen ausführt, vermindert eine glatte Oberfläche' den Abrieb und erhöht damit die Lebensdauer der Membran.Pressure accumulators of this type are used in many ways in technology - they are mainly used to store fluid under pressure and, in conjunction with throttles, to dampen pressure oscillations or pressure surges. Up to now, they have been manufactured by deep- drawing or forging a cylindrical hollow body, the free opening of which was closed by screwed or welded-on covers after the partition had been inserted: However, this manufacturing method is complex and expensive, especially for long cylindrical sections, as there is a special one for each length form is available. In addition, a deep-drawing process is only possible with certain materials. Materials of higher strength would have to be forged. It is the object of the invention to avoid the complex deep-drawing or Schmiadevorqänge and still produce a pressure accumulator with any length, clean, smooth surface and sufficient strength. This object is achieved in that the cylindrical Part consists of a steel tube , the ends of which are covered by a cover be locked. In ST ^ ns hydrochloric embodiment t of the invention Izy d frinig and is before the final VeschxiCca dan steel pipes befeotigü by a holding member c: a @@ a in the middle of the pipe. bo lid can be raised or counted, vyo-rden and horn 5L0 T iofzi'ah- or. Sch in .iede, part hergeoboll t eyerünn - - Commercially available dished ends can also be used. The advantage of the invention is that only the diaphragm shape has to be changed for different pressure accumulator sizes. A shape is no longer necessary for the pressure accumulator housing. The cover can still be forged, but this is comparatively simple and cheap, and. the shape is the same as long as the pipe diameters are the same. In terms of strength, there are no disadvantages compared to a pressure accumulator with only one cover, since the demands of two covers are the same. The fastening zones, especially when welding, the cover are from the place of the membrane insert. Stress removed so that the membrane was not thermally induced. May suffer damage. Drawn material, which is known to have a good surface, can also be used as the tube. Since the membrane also performs at least small tangentially directed movements with respect to the housing during operation, a smooth surface reduces abrasion and thus increases the service life of the membrane.

Deckel 2 hat eine Öff- nung 4 zum Einfüllen von Ges, die durch eine Schraube 5 gasdicht verschlossen ist. Der Deckel 3 hat einen Flüssigkeibsanschluß 6.
