Vorrichtung zur Verhinderung des Schieberklapperns bei DrehkolbenpumpenDevice to prevent valve rattling on rotary lobe pumps
Die Neuerung betrifft eine Vorrichtung zur Verhinderung des Schieberklapperns bei Drehkolbenpumpen.The innovation relates to a device for preventing the slide rattle with rotary lobe pumps.
Im Laufe der Entwicklung von Vakuumpumpen ist es gelungen, die zwangsläufig mit dem Pumpvorgang verbundenen Geräusche weitgehend zu beseitigen. Lediglich die bei Drehschieberpumpen durch den Schieber verursachten Geräusche, das sogenannte Schieberklappern, konnten bisher nicht vermieden werden. Bekanntlich gleiten bei den Drehschieberpumpen die Schieber im Anker, Jedoch muß das an dieser Stelle vorhandene Spiel so klein sein als irgend möglich, um die Abdichtung zwischen Saug- und Druckraum sicherzustellen. Dies hat zur Folge, daß bei den geringsten Veränderungen, z.B. bei Verwendung dickeren Oeles bei noch kalter Fumpe, bei geringfügigen Maßveränderungen infolge ungleichmäßiger Erwärmung des Ankers und beim Dazwischenkommen von kleinen Fremdkörpern, die Schieber diese Gleitbewegung im Anker nicht stockungsfrei durchführen, sondern kurzzeitig hängenbleiben und sich dann erst bewegen, wodurch sie mit einer bestimmten Geschwindigkeit auf den Pumpenring (Zylinder) auftreffen und so ein häßliches hämmerndes Geräusch erzeugen. In the course of the development of vacuum pumps, it has been possible to largely eliminate the noises inevitably associated with the pumping process. Only the noises caused by the valve in rotary vane pumps, the so-called valve rattling, could not be avoided up to now. It is well known that the vanes slide in the armature of rotary vane pumps. However, the play present at this point must be as small as possible in order to ensure the seal between the suction and pressure space. The consequence of this is that with the slightest changes, e.g. when using thicker oils when the pump is still cold, with minor dimensional changes due to uneven heating of the armature and when small foreign bodies come in between, the slide does not carry out this sliding movement in the armature without jamming, but get stuck for a short time and only then move, whereby they hit the pump ring (cylinder) at a certain speed and thus produce an ugly pounding noise.
Der Neuerung lag die Aufgabe stellung zugrunde, die Schieber an Drehschieberpumpen so auszugestalten, daß das beim Hängenbleiben und Aufschlagen des Schiebers entstehende Geräusch vermieden wird. Das Kennzeichnende ist darin zu sehen, daß die Kanten der Schieber wenigstens im Bereich ihrer Auflageflächen an der Zylinderwand mit einem elastischen Material versehen sind oder aus diesem Gestehen, In einer zweckmäßigen weiteren Ausbildung der Neuerung können die aus elastischem Material bestehenden Schieberkanten trommeiförmig ausgebildet oder mit profilartigen Erhebungen oder Aussparungen versehen sein.The innovation was based on the task, the vanes on rotary vane pumps designed in such a way that when it gets stuck and the Noise generated by the slide is avoided. The characteristic is in it to see that the edges of the slide at least in the area of their contact surfaces are provided on the cylinder wall with an elastic material or from this, in an expedient further development of the innovation The slide edges made of elastic material can be drum-shaped or provided with profile-like elevations or recesses.
In der Zeichnung ist eine geeignete Ausführungsform der Neuerung schematisch dargestellt.A suitable embodiment of the innovation is shown schematically in the drawing shown.
Man erkennt in den Figuren 1 und 2 einen Pumpenring (Zylinder) 1, einen Anker 2 mit z.B. zwei Schiebern 3, welche an ihrer die Zylinderinnenwand berührenden Fläche mit einem gummielastischen Stoff 4 überzogen sind oder aus diesem bestehen.One recognizes in Figures 1 and 2 a pump ring (cylinder) 1, a Armature 2 with e.g. two slides 3, which are attached to the inner wall of the cylinder Contacting surface are covered with a rubber elastic material 4 or consist of this.
