Description

PatentanmeldungPatent application Verfahren zur Erzielung hoher Drücke mit einem MembranverdichterMethod for achieving high pressures with a diaphragm compressor

Die Erfindung betrifft ein Verfahren zur Erzielung eines hohen Druckes mit einem Membranverdichter.The invention relates to a method for achieving a high pressure with a diaphragm compressor.

Membranverdichter werden in den Fällen eingesetzt, wo es darauf ankommt, * Diaphragm compressors are used where it matters *

das zu verdichtende Gas von jeglichen Schmiermitteln fernzuhalten.to keep the gas to be compressed away from any lubricants.

Die Grundelemente des Membranverdichters sind der Hydraulikteil und der Gasteil. Beide Teile werden durch eine geeignete Membrane voneinander getrennt. Im Deckel des Gasteiles befinden sich das Saug- und Druckventil des Verdichters. Gleichzeitig bildet der Deckel die Begrenzungsfläche der Membrane auf der Gasseite. Auf der Hydraulikseite stützt sich die Membrane auf einer mit feinen Bohrungen versehenen Platte ab, die die Verbindung zum Hydraulikkolben herstellen. Die hin- und hergehende Bewegung des Hydraulikkolbens überträgt sich auf das Hydrauliköl und von dort auf die Membrane, die nun - durch ihre oszillierende Bewegung - Gas ansaugen und verdichten kann. Dieses Prinzip eines Membranverdichters ist bekannt. M The basic elements of the diaphragm compressor are the hydraulic part and the gas part. Both parts are separated from each other by a suitable membrane. The suction and pressure valves of the compressor are located in the cover of the gas section. At the same time, the cover forms the boundary surface of the membrane on the gas side. On the hydraulic side, the membrane is supported on a plate with fine bores, which establish the connection to the hydraulic piston. The back and forth movement of the hydraulic piston is transferred to the hydraulic oil and from there to the diaphragm, which - thanks to its oscillating movement - can now suck in and compress gas. This principle of a diaphragm compressor is known. M.

Bei Zusafzverdichtern mit sehr hohen Enddrücken und somit auch relativ hohen Ansaugedrücken tritt leicht ein Membranbruch auf, der durch die Bohrungen der Platte in Verbindung mit dem hohen Gas-Ansaugedruck verursacht wird. Nun lassen sich die Bohrungen entsprechend klein dimensionieren; dieses hat aber den Nachteil zur Folge, daß der Verdichtungs-Enddruck nicht beliebig hoch gewählt werden kann. Es hat sich gezeigt, daß das Hydraul iköl bei hohem Druck sehr dicht und zäh wird. Da diese zähe Masse in den kleinen Bohrungen der Platte einen sehr großen Staudruck verursacht, treten Druckspitzen auf, die zurWith additional compressors with very high final pressures and thus also relatively high suction pressures, a diaphragm rupture easily occurs, which is caused by the holes in the plate in connection with the high gas suction pressure. Now the holes can be dimensioned correspondingly small; but this has the disadvantage that the final compression pressure cannot be selected as high as desired. It has been shown that the hydraulic iköl is very tight and tough at high pressure. Since this viscous mass causes a very high dynamic pressure in the small holes in the plate, pressure peaks occur which lead to

das maximalen Verdichtungs-Enddruckes wird also durch die kleinen Bohrungen der Platte gesetzt, die das unter hohem Druck stehende zähe Hydrauliköl einen zu starken Widerstand entgegensetzt. Wiederum müssen die Bohrungen so klein sein, weil sonst durch diese die Membrane unter Einwirkung des hohen Ga-s-Ansaugedruckes zerstört würde.the maximum compression final pressure is therefore through the small bores of the Plate set, which is too strong for the viscous hydraulic oil under high pressure Opposes resistance. Again, the holes have to be so small, otherwise this destroys the membrane under the effect of the high gas suction pressure would.

Die Erfindung zeigt ein Verfahren auf, wodurch sich der Gas-Enddruck noch weiter steigern läßt bei gleichzeitiger Entlastung" der Platte und des Hydraulikzylinders von den nicht erwünschten hohen Staudrücken.The invention shows a method whereby the final gas pressure is increased can be increased further with simultaneous relief "of the plate and the hydraulic cylinder from the undesirable high back pressures.

Das Verfahren soll mit Hilfe der Fig. 1 erläutert werden.The method is to be explained with the aid of FIG. 1.

An einem geeigneten Platz des Verdichters angeordnet befindet sich ein Ölbehälter (8), dessen Inhalt durch eine Heizung (9) erwärmt wird. Es kann sich dabei beispielsweise um eine elektrische Heizung mit Temperaturregelung handein, die es auchermöglicht, daß der Verdichter erst nach Erreichen einer bestimmten Öltemperatur in Betrieb genommen werden kann. Mit dem erwärmten öl wird über eine Umwälzpumpe (10) der Hydraulikzylinder (5) mit seinen Nebenteilen vorgewärmt und auf gewünschter Temperatur gehalten. Die Hochdruckpumpe (11), die vom Kurbel triebwerk angetrieben wird, besorgt die Erhaltung des Ölvorrates in dem Hydraulikzylinder (5) und gleicht somit die Leckage an der Abdichtung (7) aus. Das zuviel in den Hydraulikzylinder (5) eingespritzte Hydrauliköl fließt über das Druckbegrenzungsventil (12) in den Ölbehälter (8) zurück.An oil container is located at a suitable place on the compressor (8), the contents of which are heated by a heater (9). It can turn out to be for example an electric heater with temperature control it also enables the compressor to only run after a certain oil temperature has been reached can be put into operation. The hydraulic cylinder (5) and its secondary parts are preheated with the heated oil via a circulation pump (10) and kept at the desired temperature. The high pressure pump (11) that is driven by the crank engine, is concerned with maintaining the oil supply in the Hydraulic cylinder (5) and thus compensates for the leakage at the seal (7). Too much hydraulic oil injected into the hydraulic cylinder (5) flows through the Return the pressure relief valve (12) to the oil tank (8).

Die vorgewärmte Maschine und das warme Hydrauliköl bewirken nun, daß bei hohen Drücken der FlUssigkeitscharakter des Hydrauliköles erhalten bleibt und somit die Entstehung von unzulässigen Staudrücken in den Bohrungen (4) der Platte (3) vermieden werden.The preheated machine and the warm hydraulic oil now cause that at high Press the fluid character of the hydraulic oil is retained and thus the The creation of impermissible dynamic pressures in the bores (4) of the plate (3) is avoided will.
