Description

Selbsttätige Abdichtung der Stopfbüchse der Entlüftungspumpe bei Feuerlöschkreiselpumpen. Die Entlüftungspumpe wird l ei der Feuerlöschkreiselpumpe in der Regel in das Gehäuse des Getriel;es stautAicht eingekapselt. Dies hat den Nachteil, (laß ihre Stopffüchse unzugänglich ist und l:ei L"ndichtwerden nicht jederzeit nach Bedarf mid unmitteli:ar ange- zogen werden kann. Fine Al Stellung dieses l-Telstandes erscheint gera,le aus dein Grunde ii1-eratis notwendig, weil die C'ndichtigkeit zu- meist erst dann 1-einerkt wird, wenn die Ent- liiftungspumpe an der Brandstelle die ihr zu- gedachte Arl-eit nicht in ;,ewii#_ischter Weise verrichtet und dadurch wiederholt peinlichste Störungen gerade in entscheidensten Augen- Nicken vorgekommen sind. Gegenstand der Erfindung löst min diese Aufgabe vollkommen, indem die Kupplung der Entliiftungsputnpe derart angegliedert ist, <laß ihre Feder ständig auf (1:e _@tofhüch@en- Lrille drückt, und infolge ihrer Spannkraft die Stopfl-üchse auf diese Weise immer- während in gewünschter Weise dichthält. Gliederung und Wirkungsweise gehen aus beiliegender Ahhild,unh lurvor, und zwar ist: a die Welle der Entlüftungspumpe, h die Stopfl.iichsenl-rille, c: die vermittels eines Kugellagers auf h gelagerte Kupplungsfeder. c/ die ausrückuare Kupplungshälfte, e die antreil:en(le Kupplungshälfte, j' Wand des Getrie' egehätises und zugleich festes Widerlzi-er für c, x Kupplungshebel zum Ein- und Ausschalten der Kupplung.Automatic sealing of the stuffing box of the ventilation pump on centrifugal fire pumps. The priming pump is running low Fire fighting centrifugal pump usually in that Housing of the gearbox; it stows not encapsulated. This has the disadvantage, (leave their stuffed foxes is inaccessible and does not become leak-proof at any time as required mid immediately: ar an- can be pulled. Fine Al position this l-Telstandes seems straightforward for your reason ii1-eratis necessary because the leak tightness usually only becomes unanimous when the de- lift pump at the site of the fire not imagined work in an everlasting way performed and thereby repeatedly most embarrassing Disturbances especially in the most crucial eye Nods occurred. The invention solves this min Task completely by using the clutch the Entliiftungsputnpe is attached in such a way, <keep your pen open (1: e _ @ tofhüch @ en- Lrille presses, and as a result of their resilience keep the stopper in this way- while holding tight in the desired manner. Outline and mode of action go out enclosed Ahhild, unh lurvor, namely: a the shaft of the ventilation pump, h the stopper sleeve groove, c: the clutch spring supported on h by means of a ball bearing. c / the disengageable clutch half, e the parts: en (le clutch half, j 'wall of the gearbox and at the same time fixed counter for c, x clutch lever for switching the clutch on and off.

Unschwer ist zu erkennen, daß die Kupplungsfeder c sowohl in eingerücktem als auch in atis-eschaltetein Zustand der 1---ntliiftungspumpe einen ständigen Druck auf ihre Stopf-Hichse ausübt, wodurch eingangs 1 eschrie-1 ene Mißstände ausgeschaltet sind.It is not difficult to see that the clutch spring c both in the engaged as well as in atis-eschalted a state of the 1 --- ventilation pump a constant pressure exercises on her darning-Hichse, whereby 1 eschrie-1 ene grievances eliminated at the beginning are.
