Description

Schutzverkleidung für Elektrokessel. Die Leitfähigkeit des Wassers bedingt bei allen Elektrokesseln, die mit spannungsführenden blanken Teilen im Wasserraum verseben sind. ein Überfließen des Stromes zur Kesselwand. Man hat es nicht immer in der Hand, den Stromverlauf so zu beeinflussen, claß er sich, ohne Schaden anzurichten, abspielt. Es ist hinreichend bekannt, daß Ströme im Elektrokessel unter Umständen fressend auf die Metallteile wirken, die von ihnen berührt werden. Es traten an den Kesselmänteln, den Kesselböden, an den Nieten und sonstigen exponierten Stellen Anfressungen auf, die man durch Einbau von Schutzmänteln aus Metall zu verhindern versuchte, indem man die Schutzmäntel der Zerstörung aussetzte und sie von Zeit zu Zeit erneuerte.Protective covering for electric boilers. The conductivity of the water conditionally for all electric boilers with live bare parts in the water room are sunk. an overflow of the current to the boiler wall. You don't always have it in the hand to influence the course of the current in such a way that it can be used without causing damage, plays. It is well known that currents in the electric boiler under certain circumstances have a corrosive effect on the metal parts that are touched by them. It started the boiler jackets, the boiler bottoms, the rivets and other exposed areas Corrugations that can be prevented by installing protective metal jackets tried by exposing the protective cloaks to destruction and them from time renewed at time.

Auch der Sauerstoffgehalt des ,Speisewassers gibt erfahrungsgemäß Anlaß zu Anfressungen chemischer Art. Außerdem ist bekannt, daß auch das Vorkommen verschiedener Metalle im Kesselinnern zu elektrolytischen Vorgängen führt, die gleichfalls fressend wirken.Experience has shown that the oxygen content of the feed water is also there Reason for erosion of a chemical nature. It is also known that the occurrence different metals inside the boiler leads to electrolytic processes, which also appear devouring.

Man hat versucht, durch Innenanstriche mit Farbe oder farbenähnlichen Produkten diese Einwirkungen auszuschalten, sie erwiesen sich aber im Elektrokessel als gänzlich ungeeignet, da sie den im Wasser auftretenden elektrischen Spannungen nicht gewachsen waren und schon beim Einschalten von der Spannung durchschlagen-wurden.Attempts have been made to paint the interior with paint or similar ones Products to eliminate these effects, but they turned out to be in the electric boiler as completely unsuitable, since they the electrical voltages occurring in the water had not grown and were broken down by the voltage when they were switched on.

"Erfindungsgemäß wird diesem Übelstand dadurch abgeholfen, daß als Schutzmasse eine Zusammensetzung aus isolierenden Körpern mit einem im Wasser abbindenden Bindemittel gewählt wird (beispielsweise eine Mischung von Asbestfaser mit Zement. Die Stärke des Auftrages richtet sich nach den auftretenden Spannungen und beträgt stets mehrere Millimeter. Ein derartiger Masseauftrag schützt die gefährdeten Teile auch vor den Angriffen des Kesselwassers und verhindert die elektrolvtischen Wirkungen."According to the invention, this drawback is remedied in that as Protective mass a composition of insulating bodies with one that sets in water Binder is chosen (for example a mixture of asbestos fiber with cement. The strength of the order depends on the tension and amounts to always several millimeters. Such a mass application protects the endangered parts also from the attacks of the boiler water and prevents the electrolvtischen effects.
