Description
Flüssiges Reinigungsmittel zum Reinigen von Kollektoren und Schleifringen elektrischer Maschinen von aus Kohlenstaub, Fett und deren Verbrennungsprodukten bestehenden krustenartigen Schichten Die Kollektoren oder Schleifringe von Elektromotoren oder Dynamomaschinen müssen von Zeit zu Zeit gereinigt werden, um die an den Kollektor sich ansetzenden Teilchen, die aus einem Gemisch von Staub und Kohlenpartikelchen, hart gewordenem Fett, abgeriebenen Metallteilcben und deren Verbrennungsprodukten -bestehen, zu entfernen, denn sie bilden eine starke Kruste mit hohem Übergangswiderstand für die Stromabnehmer.Liquid cleaning agent for cleaning collectors and slip rings electrical machines made from coal dust, fat and their products of combustion existing crust-like layers The collectors or slip rings of electric motors or dynamo machines need to be cleaned from time to time in order to keep the collector adhering particles, consisting of a mixture of dust and carbon particles, hard grease, abraded metal parts and their combustion products -are to be removed, because they form a strong crust with high contact resistance for the pantograph.
Hierzu verwendete man bisher entweder mechanisch wirkende Mittel, wie Schmirgelleinen, oder flüssige, wie 01.So far, either mechanically acting means have been used for this purpose, like emery cloth, or liquid like 01.
Die mechanischen Reinigungsmittel haben den Nachteil, daß der Kollektor- stark angegriffen wird, indem von den Kupferlamellen Stückchen abgerieben werden. Dadurch wird der Kollektor auch häufig unrund, so daß von Zeit zu Zeit ein Abdrehen des Kollektors notwendig wird. 01 hat sich als Reinigungsmittel nicht bewährt, zumal es auch die Kruste schlecht löst. Das nachstehend beschriebene Mittel soll daher die bisherigen ersetzen.The mechanical cleaning agents have the disadvantage that the collector is severely attacked as bits of the copper lamellae are rubbed off. As a result, the collector is often out of round, so that it is necessary to turn the collector off from time to time. 01 has not proven itself as a cleaning agent, especially since it does not loosen the crust well. The means described below is therefore intended to replace the previous ones.
Das neue Mittel besteht im wesentlichen aus einem die harte Kruste zunächst ablösenden Stoff. Als solcher kommt in erster Linie Tetrachlorkohlenstoff oder Trichloräthylen in Frage. Diese Stoffe haben vor anderen Lösungsmitteln den großen Vorzug, daß sie nicht brennbar sind, sondern sogar als Feuerlöschmittel dienen können. Da das Reinigen der Kollektoren während des Laufes des Motors geschieht, können also auftretende Funken keinen Schaden anrichten. Als Träger für die gelösten Schmutzteilchen ist dem Tetrachlorkohlenstoff ein Öl beigegeben, in dem die abgelösten Schmutzteilchen nach der sehr bald erfolgenden Verflüchtigung des Tetrachlorkohlenstoffes suspendiert sind. Eine Mischung von geeignetem :)1 mit dem Tetrachlorkohlenstoff gibt eine klare Flüssigkeit von einheitlichem Aussehen, aus welcher sich der Tetrachlorkohlenstoff beim Aufbringen auf die große Oberfläche des Kollektors rasch verfluchtet, so daß dann das Öl mit den in ihm suspendierten Krusteteilchen zurückbleibt. Der Mischung können gegebenenfalls noch andere Stoffe hinzugesetzt werden.The new remedy consists essentially of a hard crust initially releasing substance. As such, carbon tetrachloride comes primarily or trichlorethylene in question. These substances have the advantage of other solvents great advantage that they are not flammable, but even serve as fire extinguishing agents can. Since the collectors are cleaned while the engine is running, sparks cannot cause any damage. As a carrier for the solved An oil is added to the carbon tetrachloride dirt particles, in which the detached Dirt particles after the very soon volatilization of the carbon tetrachloride are suspended. A mixture of suitable:) 1 with the carbon tetrachloride gives a clear liquid of uniform appearance, from which the carbon tetrachloride is made quickly cursed when applied to the large surface of the collector, so that then the oil remains with the crust particles suspended in it. The mix If necessary, other substances can also be added.
