"Wie versteht man, dass die Pumpe eine Selbstentlüftungsfunktion haben muss?

Selbstentlüftung bedeutet: Der Auslass der Pumpe befindet sich bei der Konstruktion der Pumpe auf der höchsten Stelle. Beim Befüllen der Pumpe kann es daher keine „Luftblockade“ in der Pumpe entstehen. Wenn es Gas gibt, kann es zu Kavitation kommen. Ich weiß nur, dass für das mechanische Dichtsystem PLAN23 eine manuelle Entlüftung erforderlich ist.

Nehmen wir zum Beispiel eine Doppelpumpe: Zentrifugpumpen werden in der Regel mit geschlossenen Ventilen gestartet. Wie füllt man eine Pumpe, wenn sich darin Luft befindet?

Meine persönliche Auffassung von Selbstentlüftung bedeutet, dass eine Entlüftungsvorrichtung am Pumpenkörper angebracht ist. Während des Betriebs der Pumpe sammeln sich im Laufe der Zeit kleine Mengen an Gas in den höher gelegenen Bereichen des Pumpenkörpers an. Wenn dieses Gas nicht abgeleitet wird, kann es schließlich dazu führen, dass die Pumpe nicht mehr richtig funktioniert

Ich habe dieses Problem auch bis jetzt nicht richtig verstanden. Gibt es jemanden, der mir helfen kann?

Das Prinzip ist sehr einfach – sobald man es erklärt, verstehen diejenigen, die es wissen, es sofort. Es zeigt sich hauptsächlich bei der Lösung des Problems der Selbstansaugung der Pumpe – mit vier Worten: Strahlentlüftung. Verdammt, bei dieser Frage würde ich eine Gebühr verlangen, wenn ich vor Ort im Entwurfsbüro erklären müsste.
