Description
Die Erfindung betrifft eine Rohrhalterung für Rohrbündel von Wärmetauschern, bestehend aus zwischen den Rohren im wesentlichen quer zu deren Achse verlaufenden und an den Rohren anliegenden elastischen Schläuchen mit abgeflachtem QuerschnittThe invention relates to a tube holder for tube bundles of heat exchangers, consisting of between the tubes extending substantially transversely to their axis and resting against the tubes elastic Tubes with a flattened cross-section
Eine derartige Rohrhalterung ist aus der DT-OS 910 bekannt Weiterhin ist es bekannt (vergl. CH-PS 482 160), zur Dämpfung von Schwingungen der Kühlwasserrohre in Wärmetauschern elastische Einlagen aus wasser- und wärmebeständigen Kunststoffstreifen zu verwenden.Such a pipe holder is known from DT-OS 910. It is also known (cf. CH-PS 482 160), elastic inserts to dampen vibrations of the cooling water pipes in heat exchangers to use made of water- and heat-resistant plastic strips.
Es sind auch bereits hohle Distanzstreifen vorgeschlagen worden, die relativ große Anlageflächen mit den Rohren bilden (vergL BE-PS 556 367).Hollow spacer strips have also been proposed which form relatively large contact surfaces with the pipes (compare BE-PS 556 367).
Einen Wärmetauscher, bei dem zur Abdichtung zwischen Kesselwand und einem inneren Blechmantel ein auf den Blechmantel spiralig aufgewickelter Gum-ίο mischlauch verwend'.-t wird, der mit Gas odt ' uft oder einer Flüssigkeit gefüllt ist, offenbart da 'T-Gbm 1 706 737.A heat exchanger, which is used to seal between the boiler wall and an inner sheet metal jacket A rubber ίο mixing hose that is spirally wound onto the sheet metal jacket is used, which blows with gas or is filled with a liquid, reveals da 'T-Gbm 1 706 737.
Der Erfindung liegt die Aufgabe zugrunde, eine Rohrhalterung der eingangs genannten Art zu schaffen, mit der eine noch bessere Schwingungsdämpfung als mit den bereits bekannten Mitteln erzielt werden kann.The invention is based on the object of creating a pipe holder of the type mentioned at the beginning, with which an even better vibration damping can be achieved than with the already known means.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Schläuche eine federnde Füllung enthalten, die in flüssiger Form in die zwischen die einzelnen Rohre des Rohrbündeis eingezogenen Schläuche eingefüllt und danach chemisch ausgehärtet ist Als Füllmaterial ist ein Polysulfidgummi besonders geeignet.This object is achieved according to the invention in that the hoses contain a resilient filling, which is filled in liquid form into the hoses drawn between the individual tubes of the tube bundle and then chemically cured. A polysulfide rubber is particularly suitable as a filler material.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die Rohrhalterung die Schwingungsamplituden in den meisten Fällen um mehr als das Verhältnis 25 : i und sonst um mindestens das Verhältnis 5 :1 verringert und daß die Füllung der Schläuche ihre Lebensdauer wesentlich erhöhtThe advantages achieved by the invention are, in particular, that the pipe holder reduces the vibration amplitudes in most cases by more than the ratio 25: i and otherwise by at least the ratio 5: 1 and that the filling of the hoses significantly increases their service life
