Description

Einrichtung zuin Feststellen von Korrosionen an isolierten Rohrleitungen, Behältern u. dgl., insbesondere in Kälteanlagen Die in Kalteanlagen unter Ider Isolierung an isolierten Rohrleitungnen, Behältern u. dgl. auftretenden Korrosionen werden bis jetzt erst dann erkannt, wenn die Korrosion schon so weit vorgeschritten ist, daß die korrodierten Teile unbrauchbar geworden sind. Durch die Benutzung Ider Erfindung wird die korrosionsgefährdete Stelle sofort mit dem Beginnenwollen der Korrosion festgestellt, womit jede Korrosionsmögiichkeit ausgeschaltet werden kann. Die Korrosionen unter der Isolierung kommen, wie bekannt, dadurch zustande, daß Luft durch schadhafte Stellen der Isolierung in die Isolierung gelangt und sich dort so weit abkühlt, daß ihreTaupunkttemperatur erreicht und unterschritten wird; hierbei schlägt sich in der Isolierung das in der Luft befindliche Wasser nieder, durchtränkt mit der Zeit - es dringt dauernd neue Luft in die Isolierung ein - die Isolierung bis auf die Kältemediumträgeroberfläche und leitet dort die Korrosion ein. Das zu späte Erkennen der Korrosionsherde ruft in Kälteanlagen Betriebsunterbrechungen, Materialverluste und Gefahren hervor ; es sei hierbei an die Schäden, die durch den Ausfluß von Kältemedien in die Betriebs-und Fabrikationsräume entstehen, erinnert. Die bis heute durch die Korrosion und deren Folgen alljährlich verlorengehenden Materialmengen bleiben durch die Anwendung der Erfindung erhalten, wie auch alle Gefahren, Schäden und Verluste durch die Erfindung vermieden werden.Equipment for the detection of corrosion on insulated pipelines, Containers and the like, especially in refrigeration systems, those in refrigeration systems with insulation Corrosion that occurs on insulated pipelines, containers and the like until now only recognized when the corrosion has progressed so far, that the corroded parts have become unusable. Through the use of the invention the point at risk of corrosion becomes immediately with the start of corrosion established, which means that any possibility of corrosion can be eliminated. The corrosion As is well known, the insulation is caused by the air passing through defective Places the insulation gets into the insulation and cools down there so far that that their dew point temperature is reached and undercut; this beats in the insulation the water in the air down, soaked with the Time - new air is constantly penetrating the insulation - the insulation up to the cooling medium carrier surface and initiates corrosion there. Too late Recognition of the sources of corrosion causes operational interruptions and material losses in refrigeration systems and dangers forth; it is due to the damage caused by the leakage of cold media in the operating and manufacturing rooms. Which to this day by the Corrosion and its consequences are lost every year the application of the invention as well as all hazards, damages and losses can be avoided by the invention.

In Fig. I ist z.B. eine Rohrstrecke r, die mit einer Isolierung i versehen ist, gezeichnet. In Fig. I, for example, a pipe section r, which is covered with an insulation i is provided, drawn.

Zwischen dem Rohr r und der darüber aufgebrachten Isolierung i wird eine mit feuchtigkeitsdurchlässiger Umspinnung versehene Drahtleitung d gewunden um das Rohr verlegt. Die Drahtleitung d auf der Rohrstrecke r wird unterteilt; die Enden der Drahtleitung d werden, wie gezeichnet, durch die Isolierung i nach außen geführt und dort mit Klemmen versehen ; damit wird die Rohrstrecken, die unter der gewundenen Drahtleitung d liegt, auf Durchfeuchtung hin, wie nachstehend beschrieben, kontrollierbar.Between the pipe r and the insulation i applied over it a wire line d provided with moisture-permeable wrapping is wound routed around the pipe. The wire line d on the pipe section r is divided; the The ends of the wire line d are, as shown, outwardly through the insulation i guided and provided with terminals there; so that the pipe runs that are under the twisted wire line d, for moisture penetration, as described below, controllable.

Tritt eine Durchfeuchtung der Isolierung i innerhalb der Rohrstrecke r ein, dann wird schließlich auch die Drahtumspinnung der Drahtleitung d an dieser Stelle mit durchleuchtet : in dem Augenblick, wo nun auch das Rohr r feucht wird, steht der Draht d mit dem Rohr in leitender Verbindung, was durch den Zeigerausschlag eines elektrischen Anzeigeinstrumentes, das, wie dargestellt, einerseits an eine Klemme a und andererseits an das Rohr i selhst angeschlossen ist. erkennbar wird. If moisture penetrates the insulation i within the pipe section r a, then finally the wire wrapping of the wire line d is also attached to it Body with x-rayed : at the moment when now the pipe r becomes wet, the wire d is in conductive connection with the pipe, which through the pointer deflection of an electrical indicating instrument which, as shown, connected on the one hand to a terminal a and on the other hand to the pipe i self is. becomes recognizable.

Um dauernd die ganze Rohlreitung voa Anfang liis Ende unter Kontrolle zu haben, werden alle Klemmen ce miteinauder verbunden: das Anzeigeinstrument wird vorteilhaft am Anfang der Rohrleitung an die dort vorhandene erste Klemme und an das Rohr selbst angeschaltet. Solange die Isolierung i überall trocken ist, erfolgt bei einer Messung, die z. B. durch das Niederdrücken der Taste des Anzeigeinstrumentes m bewerkstelligt wird, kein Ausschlag des Instrumentes m; erfolgt aber ein Ausschlag, dann ist das ein Zeichen dafür. daß irgendwo auf der Rohrleitung r sich eine durchfeuchtete Stelle in der Isolierung i befindet, Will man nun die Stelle finden, dann trennt man systematisch, am Ende der Rohrleitung beginnend, nacheinander die Verbindungsstellen der zusammengeschaltenten Klemmen ee; mit dem Augenblick. wobei irgeneiner I rennung. das Anzeigeinstrument stromlos wird, weiß man, daß man die durchfeuchtete Stelle eben abgeschaltet hat; damit wird die el>en abgeschaltete unterteilte Rohrstrecke, die durchfeuchtet ist, bekannt. Hiernach untersucht man die Rohrstrecke sell>st mittels Anzeigeinstrumentes m und der in Fig. 2 dargestellten Sonde s, die aus einem Isoliergriff init einer dünnen, vorn spitzen Stazhlnadel l)esteht, die leitend mit dem Anzeigeinstrument m, wie iii Fig. 2 gezeichnet, verbunden ist. Die Sonde s wird in die Isolierung systematisch nacheinander an verschiedenen Stellen der als feucht erkannten Rolirstrecke eingeführt; mit dein Augenblick, wo bei der Einführung der Sonde s in die Isolierunt, i ein Ausschlag des Anzeigeinstrumentes erfolgt, hat man den Sitz der durchfeuchteten Stelle der schadhaften Rohrstrecke genau gefunden. In order to keep the whole raw ride from beginning to end under control to have, all terminals ce are connected with one another: the indicating instrument becomes advantageously at the beginning of the pipeline to the first clamp there and to turned on the pipe itself. As long as the insulation i is dry everywhere, takes place in a measurement that z. B. by pressing the key of the display instrument m is accomplished, no deflection of the instrument m; but there is a rash, then that's a sign of it. that somewhere on the pipeline there was moisture penetrating it Place in the insulation i, if you want to find the place, then separate systematically, starting at the end of the pipe, the connection points one after the other of the interconnected terminals ee; with the moment. where some I run. the display instrument is de-energized, you know that you have the moistened area has just switched off; so that the el> en switched off subdivided pipe section, which is soaked, known. Then examine the pipe section sell> st by means of display instruments m and the probe s shown in Fig. 2, which consists of a Insulated handle with a thin, pointed needle l), which is conductive with the display instrument m, as drawn iii FIG. 2, is connected. The probe s will in the isolation systematically one after the other at different points of the as damp recognized Rolir range introduced; with your moment where when introducing the Probe s into the insulating base, i the display instrument shows a deflection the seat of the moistened part of the damaged pipe section is found exactly.

Zwecks danuernder Kontrolle aller durch eine Drahtwicklung gesicherten Rohrleitungen, Behälter u. dgl. einer Kälteanlage von einer Zentralsteile aus werden alle herausgeführten Drahtenden einer Rohrleitung o. dgl. hintereinandergeschaltet. von jeder so hintereinandergeschalteten Drahtleitung führt dann je ein Draht zur Mezentrale; hier ist es möglich, die Gesamtanlage entn-eder dauernd durch selbsttätige, signalgebende oder täglich beliebig oft von hand zu betätigende Meßanlagen zu überwachen.For the purpose of subsequent control of all secured by a wire winding Pipelines, containers and the like of a refrigeration system from a central part all lead-out wire ends of a pipeline or the like connected in series. from each wired line connected one behind the other, one wire then leads to Mezzanine; here it is possible to permanently remove the entire system by means of automatic, to monitor signaling or manually operated measuring systems as often as required every day.

Auch Korrosionen, die von innen her zum Durchbruch des Kältemediums s durch die Kältemediumträterwand führen, werden durch die Erfindung sofort festgestellt. Also corrosion, which leads to the breakthrough of the cooling medium from the inside s lead through the wall of the cooling medium drainage system, are immediately determined by the invention.
