Description
Elektromotor, der sich unter -dem Spiegel einer explosiblen Flüssigkeit befindet Die Erfindung betrifft einen Elektromotor, der sich unter dem Spiegel einer explosiblen Flüssigkeit befindet. Es ist bekannt, derartige Elektromotoren durch Öl, das unter größerem Druck steht als jene umgebende Flüssigkeit, gegen deren Eindringen zu schützen.Electric motor located under the mirror of an explosive liquid The invention relates to an electric motor, which is located under the mirror of a explosive liquid. It is known to use such electric motors Oil, which is under greater pressure than the surrounding liquid, prevents it from penetrating to protect.
Bei dieser bekannten Einrichtung kommt das Öl unmittelbar mit den Wicklungen, mit dem Anker und mit den anderen Teilen des Elektromotors in Berührung. Das Öl wirkt hierbei insbesondere auf die Isolierstoffe der Wicklung mit der Zeit ungünstig ein, so daß schließlich eine Zersetzung der Isolation erfolgt, die zum Versagen der Maschine führt.In this known device, the oil comes directly with the Windings, with the armature and with the other parts of the electric motor in contact. Over time, the oil has an effect in particular on the insulation materials in the winding unfavorable, so that finally a decomposition of the insulation takes place, which for Failure of the machine results.
Ferner ist bei Elektromotoren, die sich unterhalb eines. Flüssigkeitsspiegels befinden, bekanntlich auch bereits vorgeschlagen worden, dem Elektromotorgehäuse eine Kammer vorzulagern, die ihrerseits mit Öl gefüllt ist. Dieses Öl steht unter einem gewissen Druck und schmiert das Lager des Motors da, wo die Welle aus dem Motorgehäuse austritt. Es verhindert aber noch nicht das Eindringen der umgebenden Flüssigkeit in den Motor. Der hierzu erforderliche überdruck wird vielmehr durch eine Preßgasanlag(# erzeugt.Furthermore, with electric motors that are below a. Liquid level are, as is well known, already proposed, the electric motor housing to store a chamber in front, which in turn is filled with oil. This oil is under a certain pressure and lubricates the bearing of the motor where the shaft comes out of the Motor housing emerges. However, it does not yet prevent the surrounding area from penetrating Liquid in the engine. The overpressure required for this is rather through a compressed gas system (# generated.
Die bekannten Einrichtungen dieser Art haben den Nachteil, daß beim Versagen der Preßgasanlage die umgebende Flüssigkeit in den Elektromotor eindringen kann, wodurch sofort eine Explosionsgefahr eintritt, wenn diese Flüssigkeit explosibel ist. - Diese Nachteile werden nach der Erfindung dadurch behoben, daß das Drucköl den Motor allseitig umgibt, ohne ihn anzufüllen. Hierbei können an sich bekannte Mittel vorgesehen werden, um das Eindringen des ölen in den Motor selbst zu verhindern; beispiels= weise können hierzu Lippendichtungen verwendet werden. An die Stelle des Drucköles kann auch ein flüssiges Fett treten.The known devices of this type have the disadvantage that when If the compressed gas system fails, the surrounding liquid can penetrate into the electric motor which creates an immediate risk of explosion if this liquid becomes explosive is. - These disadvantages are eliminated according to the invention by that the pressure oil surrounds the engine on all sides without filling it. Here you can means known per se are provided to prevent the penetration of the oil into the engine prevent yourself; For example, lip seals can be used for this will. A liquid fat can also replace the pressure oil.
