Description
Uas Streben nach immer größerer Wirtschaftlichkeit der Kolbenmaschinen führt dazu, den erreichbaren Gegendruck möglichst vollkommen auszunutzen, d. h. die Expansion möglichst weit nach unten zu treiben. Außerdem kann in den Kolbenmaschinen eventuell nach geschalteten Abdampfturbinen das beste Vakuum ohne weiteres ausgenutzt werden. Es muß deshalb jede Stelle, an der Luft eintreten kann, ίο sorgfältig beseitigt werden. Während bei Dampfturbinen bereits die verschiedensten Konstruktionen üblich sind, die soweit wie möglich jeden Lufteintritt verhindern, ist dies bei den Kolbenmaschinen noch nicht der Fall. Dazu kommt noch die schädliche Wirkung der durch das Kondensat in die Kessel gelangenden Luft, die dort Zerstörungen verursacht. Diese Nachteile zu beheben, bezweckt die Stopfbuchsendichtung der im nachstehenden beschriebenen Erfindung. Es soll dadurch eine wirksame Dichtung gegenüber hohem Vakuum erzielt werden.Uas striving for ever greater economic efficiency of piston engines leads to the to use the achievable counter pressure as completely as possible, d. H. the expansion as possible to drift far down. In addition, there may be a downstream connection in the piston machines Exhaust steam turbines the best vacuum can be used without further ado. Every place where air can enter must therefore ίο be carefully eliminated. While with steam turbines The most diverse constructions are already common, which as far as possible for everyone Preventing air from entering, this is not yet the case with piston engines. In addition nor the harmful effects of the air entering the boiler through the condensate, which caused destruction there. The purpose of the stuffing box seal is to remedy these disadvantages the invention described below. It is intended to provide an effective seal against it high vacuum can be achieved.
Die Erfindung betrifft eine Stopfbuchsendichtung für Kolbenmaschinen, bei der durch Einbau von besonderen, düsenförmigen Veras teilungtringen in den Packungsraum für das flüssige, dampf- oder gasförmige Sperrmittel eine gleichmäßige Verteilung und günstigste Ausnutzung der Geschwindigkeitsenergie des Sperrmittels zur wirksamen Abdichtung erzielt wird. Dabei ist im Betrieb der Druck des Sperrmittels . so zu wählen, daß ein leichtes Wrasen der Stopfbuchse eintritt bzw. dauernd etwas Sperrflüssigkeit abfließt.The invention relates to a stuffing box seal for piston engines, in which by Installation of special, nozzle-shaped distribution rings in the packing space for the liquid, vapor or gaseous barrier agents an even distribution and cheapest Use of the speed energy of the locking means achieved for effective sealing will. The pressure of the locking means is during operation. to choose so that an easy one Vapor enters the stuffing box or some barrier fluid is constantly draining off.
Auf beiliegender Zeichnung ist die Erfindung beispielsweise dargestellt. Fig. 1 zeigt in einem Längsschnitt durch die Stopfbüchse den Einbau des düsenförmigen Verteilungsringes; Fig. 2 stellt den düsenförmigen Verteilungsring in größerem Maßstabe dar.The invention is illustrated by way of example in the accompanying drawing. Fig. 1 shows in one Longitudinal section through the stuffing box showing the installation of the nozzle-shaped distribution ring; Fig. 2 shows the nozzle-shaped distribution ring on a larger scale.
Das durch den Ringkanal S eintretende Sperrmittel tritt durch gleichmäßig auf dem Umfange verteilte Nuten 7 in düsenförmig ausgebildete Ringkanäle ein, die durch mit gegeneinander versetzten Nuten 9, 10, 11, 12 und 13 versehenen Verteüungsrmgen 1, 2, 3, 4, 5 und 6 gebildet werden, in denen der Dampf oder die Sperrflüssigkeit soviel Geschwindigkeit erhält, um mit Sicherheit auch gegen große Kolbenstangengeschwindigkeiten die etwa durch den äußeren Teil der Stopfbuchse eintretende Luft zu verdrängen. Durch etwas größeres Spiel in dem Außenteil der Stopfbuchse kann bei gleichzeitiger Vermeidung zu großer Reibungsarbeit das Dampfluft- oder Flüssigkeitsluftgewicht, das in bekannter Weise aufgefangen wird, nach außen entweichen.The locking means entering through the annular channel S enters through grooves 7 evenly distributed over the circumference into nozzle-shaped annular channels, which are formed by distributing rings 1, 2, 3, 4, 5 and 6 provided with mutually offset grooves 9, 10, 11, 12 and 13 are formed, in which the steam or the barrier liquid receives enough speed to displace the air entering through the outer part of the stuffing box with certainty even against high piston rod speeds. By slightly larger play in the outer part of the stuffing box, while avoiding excessive frictional work, the weight of the vapor air or liquid air, which is absorbed in a known manner, can escape to the outside.
