Description

Membranpumpe mit elektromagnetischem Antrieb Die Erfindung betrifft Membranluftpumpen, die mit hoher Periodenzahl arbeiten, also z. 13. direkt durch Wechselstrom oder intermittierenden Strom betätigt werden.Diaphragm pump with electromagnetic drive The invention relates to Diaphragm air pumps that work with a high number of periods, e.g. 13. straight through Alternating current or intermittent current can be operated.

Es ist bekannt, für diesen Zweck Meinbr,anen aus geformten, elastischen Blechen zu benutzen, wie sie etwa, bei Barometerdosen Verwendung finden. Die bekannten Pumpen dieser Art haben alle den übelstand eines großen schädlichen Raumes, der die Wirkung beeinträchtigt. Man muß daher große Amplituden anwenden, um einigermaßen gr6P.e Kompressions- bzw. Dilatationsgrade zu erhalten. Hierdurch wird aber die Lebensdauer der Membran verkürzt.It is known for this purpose Meinbr, anen made of molded, elastic To use metal sheets, such as those used for barometer boxes. The known Pumps of this type all have the disadvantage of a large harmful space that the effect is impaired. One must therefore use large amplitudes in order to achieve gr6P.e to obtain degrees of compression or dilation. But this is the Shortened service life of the membrane.

Um mit kleiner Amplitude arbeiten zu können, muß der schädliche Raum verkleinert werden. Zu diesem Zweck sind bereits Vorschläge gemacht worden; z. B. ist die Anbringung eines geeignet geformten Füllkörpers zwischen den Membranen angegeban worden. Damit wird aber die Absicht nur unvollkommen erreicht, und zwar aus folgenden Gründen: Es ist offensichtlich, daß die günstige Wirkung nur dann erzielt wird, wenn die Membranen bei der Kompressionsschwingung jedesmal bis fast zur Berührung miteinander oder mit denerwähnten Füllkörpern gelangen. g Doch muß ein wirklicher Anschlag auch vermieden werden, weil er eine Ab- nutzung zur Folge hat und ein lästig-es Geräusch hervorruft. Man kann nun zwar durch Regulierung des #elektromagn#etischen Teiles der Pumpe die Schwingungsamplitude recht genau einstellen. Aber das ist ungenügend, da die Lage der schwingenden Membran noch von der zu erzeugenden Druckdifferenz abhängt und bei steigendem Druckunterschied der schädliche Raum wächst.In order to be able to work with a small amplitude, the harmful space must be reduced. Proposals have already been made for this purpose; z. B. the placement of a suitably shaped packing between the membranes has been indicated. However, the intention is only incompletely achieved with this, for the following reasons: It is obvious that the beneficial effect is only achieved if the membranes almost come into contact with each other or with the aforementioned packing during the compression oscillation. g But a real attack must also be avoided because it use a waste with the result and a nuisance-it causes noise. By regulating the electromagnetic part of the pump, you can now set the oscillation amplitude very precisely. But this is insufficient, since the position of the vibrating membrane still depends on the pressure difference to be generated and the harmful space grows as the pressure difference increases.

Dieser übelstand wird erfindungsgemäß dadurch behoben, daß die der beweglichen M#embr,an gegenüberliegende feststehende Meinbran rdit einer Einstellvorrichtung versehen ist, die es erlaubt, ihr diejenigge Durchbiegung zu 'geben, die bei jeder gewünschten Belastung der Pumpe den kleinstmöglichen schädlich,-en Raum ergibt. Einen recht einfachen Aufbau der Pumpe erhält man ', wenn die zur Arbeitskammer führende Leitung zu-,gleich als Haltevorrichtung dient.This drawback is remedied according to the invention in that the movable M # embr, on opposite fixed Meinbran rd with an adjustment device is provided, which allows it to give the same amount of deflection that is necessary for each desired load on the pump results in the smallest possible harmful space. A very simple structure of the pump is obtained when it is connected to the working chamber leading line also serves as a holding device.

Ein Ausführungsbeispiel des Gegenstandes derErfindung zeigtdieZeichnung schematisch im, Schnitt.An embodiment of the subject invention is shown in the drawing schematically in, section.

Mit b ist die geformte, vom Elektromagneten in Schwingung versetzte Membran' bezeichnet. Die ihr gegenüberliegende unbewegm ZD liche: Wanda des Arbeitsraumes ist ebenfalls als Meinbran ausgebildet und der Form der Membran b matrizenartig angepaßt, so daß die Oberflächen beider Membranen zwischenraumlos zur Deckung kommen. An der Meinbranb ist die Rohrleitunge befestigt, welche die Arbeitskammer mit dem Ventilkörpere verbindet. Mittels der am Gehäuse angebrachten Einstellmutt#er d kann die Rohrleitungc in axialer Richtung bewegt und damit die Durchbiegung der Membrana den jeweiligen Betriebsbedingungen entsprechend eingestellt werden.The shaped membrane set in vibration by the electromagnet is denoted by b. The opposite immovable walla of the working space is also designed as a Meinbran and is matched to the shape of the membrane b like a matrix, so that the surfaces of the two membranes coincide without any gaps between them. The pipeline that connects the working chamber with the valve body is attached to the Meinbranb. By means of the adjusting nut d attached to the housing, the pipelinec can be moved in the axial direction and thus the deflection of the membranea can be adjusted according to the respective operating conditions.
