Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Seit längerer Zeit ist man im Spülversatzbetriebe bemüht, die Lebensdauer der Rohrkrümmer zu erhöhen, indem die der Abnutzung am stärksten ausgesetzte Rohrwand verstärkt wird. Der dem Erfindungsgegenstand eigene Fortschritt gegenüber den bekannten Konstruktionen besteht darin, daß die Verstärkung der Verschleißwand nicht im ganzen, sondern nur stufenweise erfolgt, wodurch eine Materialersparnis gegenüber den bekannten Rohrkrümmern mit durchgehend verstärkter Verschleißwand sowie eine geringere Verschleißfläche und ein geringerer Reibungswiderstand erzielt wird.For a long time, efforts have been made in flushing offset operations to increase the service life of the pipe elbows by strengthening the pipe wall most exposed to wear. The subject of the invention own progress over the known constructions is that the reinforcement of the wear wall is not in whole, but only gradually, which saves material compared to the known pipe elbows with a continuously reinforced wear wall and a lower one Wear surface and a lower frictional resistance is achieved.
Die Zeichnung veranschaulicht einen solchen Rohrkrümmer im Schnitt.The drawing illustrates such a pipe bend in section.
Der Vorgang beim Durchfließen des Spülstromes durch den Krümmer ist folgender: ,The process when the purge stream flows through the elbow is as follows:
Durch den Anprall des Spülstromes auf die schrägen Verschleißflächen b wird der Spülstrom ständig nach der Mitte des Rohres zu abgeleitet. Hierbei werden nur die höchsten Erhöhungen α im Krümmer verschlissen werden, während über die weniger dickwandigen Stellen des Krümmers der Spülstrom nur hinweggleitet, ohne sie zu beanspruchen.Due to the impact of the flushing flow on the inclined wear surfaces b , the flushing flow is constantly diverted towards the center of the pipe. In this case, only the highest elevations α in the manifold are worn out, while the flushing flow only slides over the less thick-walled parts of the manifold without stressing them.
