Description
Die vorliegende Erfindung betrifft ein Verdichteraggregat mit einem Zylinder und einem Kolben, die eine Verdichterkammer begrenzen, einem Linearantrieb zum Antreiben einer Relativbewegung von Zylinder und Kolben und einer Kapsel, die wenigstens den Zylinder und den Kolben umgibt.The The present invention relates to a compressor unit with a Cylinder and a piston defining a compression chamber, a linear drive for driving a relative movement of the cylinder and pistons and a capsule containing at least the cylinder and the Piston surrounds.
Herkömmlicherweise dient eine solche Kapsel als ein Reservoir für zu verdichtendes Gas, aus dem das Gas in die Verdichterkammer angesaugt wird, und eine Rohrleitung zum Herausführen des verdichteten Gases ist von der Verdichterkammer aus durch den Innenraum geführt.traditionally, serves such a capsule as a reservoir for gas to be compressed, from the the gas is sucked into the compression chamber, and a pipeline to lead out of the compressed gas is from the compressor chamber through the Interior led.
Ein Problem dieser herkömmlichen Verdichteraggregate liegt darin, dass der gasgefüllte Innenraum und die ihn einschließende Kapsel nicht nur Betriebsgeräusche des Verdichters abfangen, sondern auch die Abgabe von Wärme an die Umgebung behindern. Wärme, die im Betrieb des Verdichters durch adiabatische Kompression des Gases in der Verdichterkammer erzeugt wird, geht zu einem Teil in Zylinder und Kolben über und erwärmt schließlich das Gas in dem Innenraum rings um Zylinder und Kolben. Durch diese Erwärmung reduziert sich die Masse des in jedem Bewegungszyklus des Kolbens eingesaugten und verdichteten Gases, was den Wirkungsgrad des Verdichters beeinträchtigt.One Problem of this conventional Compressor units lies in the fact that the gas-filled interior and the him enclosing Capsule not only operating noise of the compressor, but also the release of heat to the Obstruct environment. Warmth, in the operation of the compressor by adiabatic compression of the Gas generated in the compression chamber goes to a part in Cylinder and piston over and warmed up after all the gas in the interior around the cylinder and piston. Through this warming reduces the mass of every movement cycle of the piston sucked and compressed gas, which improves the efficiency of the compressor impaired.
Ein weiteres Problem hängt zusammen mit dem Aufbau der herkömmlichen Linearverdichter. Diese umfassen im Allgemeinen einen in einem Luftspalt eines Elektromagneten linear hin und her beweglichen permanentmagnetischen Anker. Diese Linearantriebe zeichnen sich dadurch aus, dass den die auf den Anker wirkende Antriebskraft direkt, ohne zwischengeschaltete Hebel oder dergleichen und folglich praktisch ohne Reibungsverluste auf den Kolben übertragen werden kann, doch ist, anders als bei einem herkömmlichen rotatorischen Antrieb, die Amplitude der Kolbenbewegung nicht konstruktionsbedingt vorgegeben, sondern kann durch die Stärke des auf den Anker einwirkenden Magnetfeldes beeinflusst werden. Um einen hohen Wirkungsgrad des Verdichters zu erzielen, sollte die Verdichterkammer am oberen Totpunkt der Kolbenbewegung so klein wir irgend möglich sein, doch sollte auch vermieden werden, dass am Totpunkt Zylinder und Kolben gegeneinander schlagen, um die Betriebsgeräusche des Verdichters und die Materialbeanspruchung in Grenzen zu halten.One further problem depends along with the construction of the conventional Linear compressor. These generally include one in an air gap of an electromagnet linearly reciprocating permanent magnetic Anchor. These linear drives are characterized by the fact that the driving force acting on the anchor directly, without intermediary Lever or the like and thus virtually no friction losses transferred to the piston can be, but unlike a conventional rotary drive, the amplitude of the piston movement is not determined by design, but can by the strength of the be influenced on the armature acting magnetic field. To one To achieve high efficiency of the compressor, the compressor chamber should be at top dead center of piston movement as small as we possibly can but it should also be avoided that at the dead center cylinder and Pistons against each other to beat the operating noise of the Compressor and the material stress to be limited.
Aufgabe der vorliegenden Erfindung ist, ein Verdichteraggregat der eingangs genannten Art anzugeben, das eine effiziente Ableitung der in der Verdichterkammer frei werdenden Wärme ermöglicht und/oder trotz hohen Wirkungsgrades eine übermäßige Materialbeanspruchung oder Geräuschentwicklung durch Gegeneinanderschlagen von Zylinder und Kolben vermeidet.task The present invention is a compressor unit of the above specify the type required for the efficient derivation of Compressor chamber released heat allows and / or despite high Efficiency an excessive material stress or noise avoids by hitting the cylinder and piston against each other.
Die Aufgabe wird gelöst, indem bei einem Verdichteraggregat mit einem Zylinder und einem Kolben, die eine Verdichterkammer begrenzen, ein Linearantrieb zum Antreiben einer Relativbewegung von Zylinder und Kolben und einer Kapsel, die wenigstens den Zylinder und den Kolben umgibt, anstelle einer Ansaugöffnung eine Auslassöffnung der Verdichterkammer in einen Innenraum der Kapsel mündet. Dadurch steht, wenn das Verdichteraggregat in Betrieb ist, der Innenraum der Kapsel unter hohem Druck. Zwar ist das von der Verdichterkammer ausgestoßene verdichtete Gas erheblich wärmer als das zuvor angesaugte Niederdruckgas, so dass Zylinder und Kolben, wenn sie im Wesentlichen nur über das Gas des Innenraums ihre Wärme an die Umgebung abgeben können, im stationären Betrieb nicht kälter als dieses Gas sein können, doch ist dessen Wärmeleitfähigkeit aufgrund seiner hohen Dichte um ein Vielfaches größer als die des unverdichteten Gases, so dass eine Überhitzung von Zylinder und Kolben dennoch zuverlässig vermieden werden kann.The Task is solved in a compressor unit with a cylinder and a piston, which limit a compression chamber, a linear drive for driving a relative movement of cylinder and piston and a capsule, which surrounds at least the cylinder and the piston, instead of one suction an outlet opening the compression chamber opens into an interior of the capsule. Thereby is when the compressor unit is in operation, the interior the capsule under high pressure. While that's from the compression chamber expelled compressed gas considerably warmer as the previously sucked low-pressure gas, so that cylinder and piston, if they are essentially just about the gas of the interior their heat can give to the environment, in the stationary Operation not colder than this gas can be but its thermal conductivity is because of its high density many times greater than that of the uncompacted gas, allowing overheating of cylinder and Pistons still reliable can be avoided.
Ein weiterer Effekt, der sich aus dem Vorhandensein des verdichteten Gases in der Zylinder und Kolben umgebenden Kapsel ergibt, ist, dass der hohe Druck des verdichteten Gases auf die Kolbenrückseite wirkt. Daher muss der Linearantrieb 1 im Wesentlichen nur in einer Expansionsphase der Verdichterkammer Antriebsarbeit leisten, wenn der Kolben entgegen dem Druck des verdichteten Gases des Innenraums aus dem Zylinder herausgezogen wird. Die Gegenbewegung des Kolbens erfordert kaum externe Antriebskraft, denn der Druck des Gases im Innenraum reicht im Wesentlichen aus, um den Kolben zurück zu treiben. Wenn der Linearantrieb während der Kompressionsphase überhaupt keine Antriebsarbeit leisten würde, dann käme die Kolbenbewegung kurz vor dem oberen Totpunkt zum Stillstand, wenn die Drücke in der Verdichterkammer und im Innenraum der Kapsel gleich werden. Es genügt eine kleine Menge an Antriebsenergie des Linearantriebs während der Kompressionsphase, um diese Druckgleichgewichtsstellung zu überwinden und den Inhalt der Verdichterkammer auszutreiben. Die Energie, mit der im Falle von Druckschwankungen Zylinder und Kolben gegeneinander stoßen können, liegt in der Größenordnung dieser Antriebsenergie und kann daher wesentlich kleiner gehalten werden als im Falle eines Verdichters, bei dem der Linearantrieb in der Kompressionsphase gegen den sich in der Verdichterkammer aufbauenden Druck arbeiten muss.One further effect resulting from the presence of the compacted Gases in the cylinder and piston surrounding capsule is, that the high pressure of the compressed gas on the piston back acts. Therefore, the linear actuator 1 essentially only in one Expansion phase of the compressor chamber drive work, though the piston against the pressure of the compressed gas of the interior is pulled out of the cylinder. The counter-movement of the piston hardly requires external driving force, because the pressure of the gas in the Interior is essentially sufficient to drive the piston back. When the linear drive during the compression phase none at all Drive work, then it would come the piston movement stops shortly before top dead center, when the pressures in the compression chamber and in the interior of the capsule become the same. It is sufficient a small amount of drive power of the linear drive during the Compression phase to overcome this pressure equilibrium position and expelling the contents of the compression chamber. The energy, with in the case of pressure fluctuations cylinder and piston against each other bump can, lies in the order of magnitude this drive energy and therefore can be kept much smaller be as in the case of a compressor in which the linear actuator in the compression phase against itself in the compression chamber has to work constructive pressure.
Vorzugsweise ist der Kolben in dem Zylinder gasdruckgelagert. Gegenüber einer Ölschmierung hat die Gasdrucklagerung den Vorteil, eine praktisch reibungsfreie Kolbenbewegung zu ermöglichen. Die Wärmeableitung vom Kolben über ein Gasdrucklager ist weniger effizient als über einen Ölfilm, doch ist dies im vorliegenden Fall nicht kritisch, da der Kolben über das Hochdruckgas des Innenraums ausreichend Wärme abgeben kann.Preferably, the piston is gas pressure-bearing in the cylinder. Compared to an oil lubrication, the gas pressure bearing has the advantage of allowing a practically frictionless piston movement. The Heat dissipation from the piston via a gas bearing is less efficient than via an oil film, but this is not critical in the present case because the piston can release sufficient heat through the high pressure gas of the interior.
Um das Gasdrucklager zu speisen, sind vorzugsweise Bohrungen in einem Mantel des Zylinders vorgesehen, die einen Spalt zwischen dem Mantel und einer Mantelfläche des Kolbens mit dem Innenraum verbinden.Around to feed the gas pressure bearing are preferably holes in one Cloak of the cylinder provided a gap between the mantle and a lateral surface connect the piston to the interior.
Ferner können Kanäle zum Zuführen von Druckgas aus der Verdichterkammer in den Spalt sich zwischen einer Stirnfläche und der Mantelfläche des Kolbens erstrecken. Diese Kanäle erleichtern die Aufrechterhaltung des Gasdrucklagers in Nähe des oberen Totpunkts, wenn aufgrund des Druckausgleichs bzw. des Überdrucks in der Verdichterkammer der Zustrom von Gas aus dem Innenraum über die Bohrungen des Mantels aussetzt.Further can channels for feeding of compressed gas from the compression chamber into the gap between a face and the lateral surface of the Extending piston. These channels facilitate the maintenance of the gas bearing near the top Dead center, if due to pressure equalization or overpressure in the compression chamber the influx of gas from the interior over the Bores of the shell exposes.
Die Kanäle können als Bohrungen oder als offene Rillen ausgeführt sein.The channels can be designed as holes or as open grooves.
Die Auslassöffnung der Verdichterkammer kann im Kolben gebildet sein. So steht eine gesamte Stirnfläche des Zylinders zur Verfügung, um dort ein Einlassventil mit großer Querschnittsfläche und dementsprechend geringem Druckabfall unterzubringen.The outlet the compression chamber may be formed in the piston. That's how one stands entire face of the cylinder available, There is an inlet valve with a large cross-sectional area and accommodate accordingly low pressure drop.
Eine Sauggasleitung ist vorzugsweise durch den Innenraum zur Verdichterkammer geführt, um das Sauggas schnell und mit geringer Erwärmung durch das Druckgas des Innenraums der Verdichterkammer zuzuführen.A Suction gas line is preferably through the interior to the compression chamber guided, to the suction gas quickly and with little warming by the compressed gas of the Interior of the compression chamber feed.
