Beschreibung:Description:

Reinigungsmittelauffanggerät zur Verdichterreinigung von Flugzeugtriebwerken.Detergent collection device for cleaning compressors of aircraft engines.

Stand der Technik:State of the art:

Alle Triebwerksverdichter des Triebwerkes General Elektric CF34 sind im Rahmen der 300h Kontrolle zu reinigen. Hohe Verunreinungen des Verdichters führen zum Leistungsverlust des Triebwerkes. Die Auffangvorrichtung soll dort angewand werden, wo die Entsorgungssysteme (Kanalisation) nicht mit einer Emulsionsspaltanlage ausgrüstet sind. Das Eindringen von Ölresten und Brennkammerrückständen in die Kanalisation würden zu starken Umweltbelastungen führen.All engine compressors of the General Electric CF34 engine must be cleaned as part of the 300-hour inspection. High levels of contamination in the compressor lead to a loss of engine performance. The collection device should be used where the disposal systems (sewage system) are not equipped with an emulsion splitting system. The penetration of oil residues and combustion chamber residues into the sewage system would lead to severe environmental pollution.

Problem: Issue :

Die in Anspruch 1 bis 5 angegebene Erfindung legt das Problem zugrunde, eine Auffangvorrichtung zu schaffen, die gewährleistet, daß Öl und Brennkammerrückstände nicht in die Entsorgungssyteme gelangen. Alle herunterfallenden und vom Fan verwirbelten Flüssigkeitsteiichen werden aufgefangen. Es wird dadurch gewährleistet, daß die Auffangwanne so hoch wie möglich angebracht wird (direkt unter dem Triebwerk).The invention specified in claims 1 to 5 is based on the problem of creating a collecting device that ensures that oil and combustion chamber residues do not enter the disposal systems. All liquid particles falling down and swirled by the fan are collected. This is ensured by installing the collecting tray as high as possible (directly under the engine).

Erfindung:Invention:

Das Problem wird mit den Maßnahmen des Anspruchs 1 bis 5 gelöst.The problem is solved by the measures of claims 1 to 5.

Vorteilhafte Wirkungen der Erfindung:Advantageous effects of the invention:

Die Konstruktion ist ohne Änderung für das linke und rechte Triebwerk verwendbar. Der Verdichterwaschvorgang ist ohne hohen Personalaufwand auf jeden Flughafen, auf der die Maschine gewartet wird, durchführbar. Die Standzeit der Maschine verringert sich. Bestehende und immer höherwerdende Anforderungen der Umweltschutzvorschriften werden eingehalten.The design can be used for the left and right engines without modification. The compressor washing process can be carried out without high personnel costs at any airport where the machine is serviced. The machine's downtime is reduced. Existing and increasingly stringent requirements of environmental protection regulations are met.

Weiterbildung der Erfindung:Further development of the invention:

Vorteilhafte Ausgestaltung der Erfindung sind in den Ansprüchen 2 bis 4 angegeben.Advantageous embodiments of the invention are specified in claims 2 to 4.

Die Verbindung von Ansprüchen 1,2,4 und 5 sind optimal.The combination of claims 1,2,4 and 5 is optimal.

Darstellung der Erfindung:Description of the invention:

Das Ende des Umlenkrohres (5) ist diffusorförmig ausgelegt, damit die austretende Flüssigkeit und vor ailem die austretende Luft, weiche einen sehr hohen Anteil von Flüssigkeit aufweist, in ihre Geschwindigkeit herabgesetzt wird. Dadurch kann sich der "Nebel" an den Rohraußenwänden absetzen und in die Auffangvorrichtung tropfen. Der Vorhang (7) ist etwas breiter und länger. Er hängt innerhalb der Auffangvorrichtung.The end of the deflection pipe (5) is designed in the shape of a diffuser so that the speed of the escaping liquid and especially the escaping air, which has a very high proportion of liquid, is reduced. This allows the "mist" to settle on the outside walls of the pipe and drip into the collecting device. The curtain (7) is slightly wider and longer. It hangs inside the collecting device.

Claims (5)

Schutzanspmciie'uRd-BesefafeibuRa--^Protective measures and protection measures--^ 1) Fahrbare Auffangvorrichtung mit angeflanschter Auffangwanne und Umlenkrohr.1) Mobile collecting device with flanged collecting tray and deflection pipe. dadurch gekennzeichnet,characterized, daß die angeflanschte Auffangwanne (1) mit zwei Stützstreben (3) an der Oberkannte der Auffangvorrichtung befestigt ist. Die Auffangwanne ist leicht der Länge nach gewölbt und läuft schräg in den Auffangbehälter ab. (Fig 1)that the flanged collecting tray (1) is attached to the upper edge of the collecting device with two support struts (3). The collecting tray is slightly curved lengthwise and runs diagonally into the collecting container. (Fig 1) 2) Auffangvorrichtung nach Anspruch 12) Collecting device according to claim 1 dadurch gekennzeichnet,characterized, daß ein Umlenkrohr (5) an der Oberkante der Auffangvorrichtung (8) befestigt ist. Das obere Teil des Umlenkrohres (5) ragt dabei über der Oberkante und das Ende des Umienkrohres (5), daß ca. 80 Grad gebogen ist, in die Auffangvorrichtung. Die Vorrichtung kann man so von hinten auf das Triebwerk ziehen und die zu bremsenden Räder (9) feststellen.that a deflection tube (5) is attached to the upper edge of the collecting device (8). The upper part of the deflection tube (5) protrudes above the upper edge and the end of the deflection tube (5), which is bent at approx. 80 degrees, into the collecting device. The device can then be pulled onto the engine from behind and the wheels to be braked (9) can be secured. 3) Auffangvorrichtung nach Anspruch 23) Collecting device according to claim 2 dadurch gekennzeichnet,characterized, daß ein Umlenkrohr (5) zuerst am Abgaskonus befestigt wird. Die Auffangvorrichtung kann seitlich unter das Triebwerk geschoben werden, dabei den Vorhang aus Kunststoff (7) am Verriegeiungsbolzen (6) öffnen und durch das Schanier (2) zur Seite wegdrehen, danach wieder schließen (Fig. 1 ohne 5). Das Umlenkrohr wird mit Haltebändern (10) befestigt (Fig. 2).that a deflection pipe (5) is first attached to the exhaust cone. The collecting device can be pushed sideways under the engine, open the plastic curtain (7) at the locking bolt (6) and turn it to the side using the hinge (2), then close it again (Fig. 1 without 5). The deflection pipe is attached with retaining straps (10) (Fig. 2). 4) Auffangvorrichtung nach Anspruch 1 bis 34) Collecting device according to claims 1 to 3 dadurch gekennzeichnet,characterized, daß die Auffangvorrichtung von innen und außen an den Verbindungssteiien mit einem Dichtungsmittel versiegelt ist. Zusätzlich ist die Auffangvorrichtung noch mit einem Öl und Bezinbeständigen Farbanstrich versehen. Die Räder (9) der Auffangvorrichtung können in der Höhe so unterschiedlich angebaut werden, daß eine Ecke den tiefsten Punkt aufweist und man dort eine Ablaßvorrichtung (4) anbringen kann.that the collecting device is sealed on the inside and outside at the connecting parts with a sealant. In addition, the collecting device is also provided with an oil and petrol-resistant paint coating. The wheels (9) of the collecting device can be installed at different heights so that one corner has the lowest point and a draining device (4) can be installed there. 5) Auffangvorrichtung nach Anspruch 1 -45) Collecting device according to claim 1 -4 dadurch gekennzeichnet,characterized, daß das Umlenkrohr (5) um ca. 80 Grad gebogen ist. Der obere Druchmesser des Umlenkrohres (5) ist etwas größer als der Enddruchmesser der Abgasdüse, auf der das Rohr geschoben wird. Das erste Stück des Umlenkrohres (5) ist von innen gummibeschichtet, um unnötige Kratzer auf der Abgasdüse zu vermeiden. Das Ende des Umlenkrohres (5) ist entweder gleichbleibend im Durchmesser oder diffusorförmig ausgelegt.that the deflection pipe (5) is bent by approx. 80 degrees. The upper diameter of the deflection pipe (5) is slightly larger than the end diameter of the exhaust nozzle on which the pipe is pushed. The first part of the deflection pipe (5) is rubber-coated on the inside to avoid unnecessary scratches on the exhaust nozzle. The end of the deflection pipe (5) is either designed with a constant diameter or in a diffuser shape.
