Description
Elektromotorisch angetriebene Freischwingerpumpe Die Neuerung besteht darin, besondere Konstruktionselemente für elektromagnetische Freischwingerpumpen anzugeben, die sich dazu eignen, solche Pumpen als Massenartikel einfach und wirtschaftlich herzustellen und zusammenzubauen. Electrically driven cantilever pump The innovation exists therein, special construction elements for electromagnetic cantilever pumps indicate which are suitable for making such pumps as mass-produced items easily and economically manufacture and assemble.
Hierbei ist zugleich erreicht, dass die Pumpe durch elektrische Doppelisolation den elektrischen Sicherheitsvorschriften entspricht.This also means that the pump has double electrical insulation corresponds to the electrical safety regulations.
In den Abbildungen ist ein Ausführungsbeispiel der Neuerung dargestellte In Figur 1 dient der Kolben 1 aus magnetisierbarem Material gleichzeitig als Anker des elektromagnetischen Systems.In the figures, an embodiment of the innovation is shown In Figure 1, the piston 1 made of magnetizable material also serves as an anchor of the electromagnetic system.
Er ist achsial durchbohrt, um der Pumpflüssigkeit den Durchtritt zu gestatten. Der Kolben bewegt sich in dem zylindrisch gestalteten Teil des Stators. Der Stator besteht auf seinen beiden Enden aus zwei kreisförmigen achsial durchbohrten Scheiben 2 aus magnetisierbarem Werkstoff, z. B. Weicheisen. Zwischen diesen beiden Scheiben befindet sich der Spulenkörper 3 aus Isolierstoff. Der Spulenkörper dient dazu, die Spule 4 aufzunehmen und ihn elektrisch von dem Stator zu isolieren. Der Spulenkörper 3 weist in seiner inneren Öffnung zwei verschieden grosse Durchmesser auf. In dem Teil mit dem grösseren Durchmesser befindet sich ein aus magnetisierbarem Material bestehender Ringkörper 5. Nach aussen ist der Stator mit einem aus magnetisierbarem Werkstoff bestehenden Mantel 6 versehen. Die Teile 2,5 und 6 stellen den elektromagnetisch wirksamen Teil des Stators dar. Der Magnetfluss ist jedoch durch den Spulenkörper 3 an der Stelle 7 unterbrochen. Durch diese Gestaltung entsteht der Stator als geschlossener Zylinder, der achsial durchbohrt ist.It is axially pierced in order to allow the pump fluid to pass through allow. The piston moves in the cylindrically shaped part of the stator. The stator consists of two circular axially drilled holes on both ends Discs 2 made of magnetizable material, for. B. soft iron. Between these two Discs is the bobbin 3 made of insulating material. The bobbin is used to take up the coil 4 and electrically isolate it from the stator. Of the The bobbin 3 has two diameters of different sizes in its inner opening on. In the part with the larger diameter there is a magnetizable Material of existing ring body 5. To the outside, the stator is made of magnetizable Material existing jacket 6 is provided. Parts 2,5 and 6 represent the electromagnetic effective part of the stator. However, the magnetic flux is through the coil body 3 interrupted at point 7. This design creates the stator as a closed one Cylinder that is axially pierced.
In diese achsiale Durchbohrung wird nunmehr ein besonders gestaltetes Profilrohr 8 aus nichtmagnetisierbarem Werkstoff z. B. Kunststoff eingeschoben. Dieses stellt an seinem oberen Ende 9 die Einflussöffnung für die Pumpfliissigkeit dar und ist am anderen Ende als dünnwandiger Hohlzylinder gestaltet. Dieser dünnwandige Hohlzylinder dient einmal dem Kolben 1 als Lauffläche und schirmt zum anderen den Stator von der Pumpflüssigkeit ab. Diese Abschirmung hat die doppelte Aufgabe zu erfüllen, nämlich dem Anker Korrossionsschutz und dem ganzen System elektrischen Berührungsschutz zwischen Flüssigkeit und Stator zu sichern. Der Stator mit dem Rohrstück 8 wird als ganzes in einen aus Isolierstoff z. B. Kunststoff hergestellten Topf 10 gesteckt. Dieser Topf wird wiederum durch einen die Austrittsöffnung 11 enthaltenden Deckel 12 geschlossen. An seiner Innenseite ist der Deckel 12 mit einem vorspringenden Rand 13 versehen, der zur Zentrierung und Abdichtung des Rohrstückes 8 dient. Im übrigen liegt der Deckel unmittelbar auf dem Stator auf und wird in dieser Stellung durch einen Sprengring 14 festgehalten.A specially designed bore is now made in this axial through-hole Profile tube 8 made of non-magnetizable material z. B. Plastic inserted. At its upper end 9, this constitutes the inlet opening for the pumped liquid and is designed as a thin-walled hollow cylinder at the other end. This thin-walled one Hollow cylinder serves as a running surface for piston 1 and shields the other Stator from the pump liquid. This shielding does the double job too fulfill, namely the anchor corrosion protection and the whole system to secure electrical contact protection between the liquid and the stator. The stator with the pipe section 8 as a whole in a made of insulating material z. B. plastic produced Pot 10 stuck. This pot is in turn the outlet opening 11 containing lid 12 closed. On its inside, the cover 12 is provided with a projecting edge 13 provided, which is used for centering and sealing the pipe section 8 serves. Otherwise, the cover rests directly on the stator and is in held in this position by a snap ring 14.
Durch die nach der Neuerung vorgeschlagene besondere Formgebung und Zusammensetzung der beschriebenen Teile wird durch das Rohrstück 8 und den Abschlussdeckel 12 ein in sich geschlossener dichter und elektrisch isolierter Zylinderraum geschaffen, in dem sich der Kolben 1 bewegt. Diese Bewegung erfolgt durch die elektromagnetische Erregung des Stators, indem sie den Kolben in Richtung der Pumpflüssigkeit anzieht. Beim Nachlassen der elektromagnetischen Erregung wird der Kolben durch die Rückstellfeder 15 wieder in die Ausgangslage zurückgedrückt.Due to the special shape proposed after the innovation and Composition of the parts described is through the pipe section 8 and the end cover 12 a self-contained, sealed and electrically insulated cylinder space is created, in which the piston 1 moves. This movement is done by the electromagnetic Excitation of the stator by pulling the piston in the direction of the pumping liquid. When the electromagnetic excitation is released, the piston is pushed by the return spring 15 pushed back into the starting position.
Die Rückstellfeder stützt sich auf der einen Seite auf den Innenrand des Abschlussdeckels 12 und auf der anderen Seite gegen den Kolben bzw. gegen das Kolbenventil 16 ab. Das Kolbenventil 16 kann in bekannter Weise als federloses Platteventil ausgeführt sein. Es ist nach der Neuerung so ausgebildet und gleichzeitig so gestaltet, dass es die Rückstellfeder 15 in ihrer zentrierten Lage festhält.The return spring is supported on one side on the inner edge of the end cover 12 and on the other side against the piston or against the Piston valve 16 from. The piston valve 16 can in a known manner as a springless plate valve be executed. According to the innovation, it is designed and at the same time designed in such a way that that it holds the return spring 15 in its centered position.
In Figur 2 sind die einzelnen Konstruktionsteile derart räumlich aufeinander dargestellt, wie sie durch Zusammenschieben zur fertigen Pumpe zusammengedrückt werden können.In Figure 2, the individual structural parts are spatially on top of each other shown how they are compressed by pushing together to form the finished pump can be.
