Description
Wasserdicht gekapselte elektrische .Maschine Die Erfindung betrifft eine wasserdicht gekapselte elektrische Maschine, insbesondere zum Antrieb von Leckpumpen. Diese Pulli-,peil sollen das bei Leckwerden eines Schiffes eindringende Wasser wieder aus dem Schiffsinnern herausdrücken. Der Motor arbeitet dabei im allgemeinen im Luftraum, kann aber bei größeren Lecks völlig überflutet werden.Waterproof encapsulated electrical machine. The invention relates to a waterproof encapsulated electrical machine, especially for driving leakage pumps. These pulli, peils are intended to restore the water that penetrates a ship if it leaks from inside the ship. The engine works in general Airspace, but can be completely flooded in the event of larger leaks.
Der Motor muß daher bekanntlich völlig wasserdicht gekapselt sein, kann aber nicht, wie sonst üblich, durch einen außen über die Oberfläche geblasenen Luftstrom gekühlt werden, da bei Überflutung der Kühlventilator außerordentlich hohe Leistung aufnehmen würde. Um aber trotzdem günstige Abmessungen zu erhalten, verwendet man zweckmäßig Wasserkühlung.As is well known, the motor must therefore be completely watertight, but cannot, as is usually the case, with an outside blown over the surface Airflow are cooled, as the cooling fan is extraordinary when flooded would absorb high power. But in order to still get favorable dimensions, it is advisable to use water cooling.
Bei Wasserkühlmänteln und ähnlichen Einrichtungen, z. B. Rohrschlangen, besteht aber immer die Gefahr des Undichtwerdens, insbesondere bei Seewasser, wo mit starker Korrosion zu rechnen ist. Bei einer bisher üblichen bekannten Anordnung, wo die Innenluft des Motors mit dem Kühlmantel in direkte Berührung kommt, besteht die Gefahr, daß gelegentlich auch Wasser ins Motorinnere eindringt, auch wenn der Motor im Luftraum arbeitet.In water cooling jackets and similar devices, e.g. B. pipe coils, but there is always the risk of leakage, especially with seawater, where severe corrosion is to be expected. In a previously common known arrangement, where the internal air of the motor comes into direct contact with the cooling jacket the risk that water occasionally gets into the engine, even if the Motor in the airspace is working.
Die Erfindung vermeidet diese Gefahr dadurch, daß bei wasserdicht gekapselten elektrischen Maschinen mit Wasserkühlkanälen, die das Maschinengehäuse umgeben und durch einen Kühlmantel gebildet werden, der Kühlmantel die Kühlkanäle allseitig umschließt, dabei aber keinen Bestandteil der wasserdichten Kapselung der elektrischen Maschine oder des Maschinengehäuses bildet.The invention avoids this risk by being waterproof encapsulated electrical machines with water cooling ducts that form the machine housing surrounded and formed by a cooling jacket, the cooling jacket the cooling channels Enclosed on all sides, but not part of the waterproof encapsulation the electrical machine or the machine housing.
Dadurch wird erreicht, daß eine etwaige Korrosion sich nur auf den Kühlmantel, nicht aber auf das Motorgehäuse auswirkt. Die häuse einer Maschine mit den Lagerschilden 2t und 3 dar. Die Maschine ist an sich völlig wasserdicht geschlossen und in dieser Form auch ohne den Kühlmantel bereits betriebsfähig, wenn auch im Luftraum nur für kürzere "Zeit. Über das Gehäuse i wird gemäß der Erfindung der Kühlmantel q. aufgebracht, am besten durch Schrumpfen oder Pressen. Wie die Abbildung zeigt, ist der Kühlmantel so ausgebildet, daß er keinen Bestandteil der Motorkapselung bildet. Der Mantel 4 ist von Wasser über die Stutzen 5 und 6 durchflossen.This ensures that any corrosion only affects the Cooling jacket, but not affect the motor housing. the housing a machine with the end shields 2t and 3. The machine is complete in itself closed watertight and already operational in this form without the cooling jacket, even if in the air space only for a short time. About the housing i is according to the invention the cooling jacket q. applied, preferably by shrinking or pressing. As the Figure shows, the cooling jacket is designed so that it is not part of the Forms engine encapsulation. The jacket 4 is traversed by water via the nozzles 5 and 6.
