G. A. GREEVEN in BRÜHL bei KÖLN. Neuerung an Pulsometern. GA GREEVEN in BRÜHL near COLOGNE. Innovation in pulsometers.
Die Dampfeinströmung wird bei diesem einkammerigen Pulsometer nicht durch einen beweglichen Mechanismus regulirt; das Dampfabsperrventil befindet sich über dem Pumpkammerhals und läfst während des Betriebes den Dampf ununterbrochen einströmen, und zwar in der vollen Stärke, wie sie genügt, um einen entsprechend grofsen zweikammerigen Pulsometer zur höchsten Zahl von Pulsationen zu bringen. Der Dampf treibt hierbei das Wasser kräftig und schnell nach unten, bis die Condensation entsteht, deren Einflufs er nicht zu überwinden im Stande ist. Es gewinnt daher der Druck im Saugrohr das Uebergewicht und beginnt die Saugperiode, welche mit Eintritt des Gleichgewichts in der Pumpkammer ihr Ende erreicht, und dieses tritt, selbst bei voller Oeffnung des Dampfabsperrventiles, erst ein,, wenn das aufsteigende Wasser bis in den oberen, engsten Theil des Halses gelangt. Auf diese Weise erzeugt sich fortwährender Wechsel zwischen Druck und Vacuum, welcher regelmäfsige Pulsationen zur Folge hat.With this single-chamber pulsometer, the inflow of steam is not controlled by a movable one Mechanism regulates; the steam shut-off valve is located above the pump chamber neck and allows the steam to flow in continuously during operation, and to be sure, in the full strength as it is sufficient for a correspondingly large two-chambered one To bring the pulsometer to the highest number of pulsations. The steam drives that Water forcefully and quickly downwards until the condensation arises, the influence of which he does not is able to overcome. The pressure in the intake manifold therefore gains the upper hand and the suction period begins, which begins when equilibrium is reached in the pumping chamber End reached, and this occurs, even when the steam shut-off valve is fully open, when the rising water reaches the upper, narrowest part of the throat. To this In this way, there is a constant alternation between pressure and vacuum, which is a regular one Results in pulsations.
Ferner liegt bei diesem Pulsometer die Condensationslinie höher als die Druckkanalöffnung.Furthermore, the condensation line in this pulsometer is higher than the pressure channel opening.
Dieses hat den Zweck der Dampfersparnifs; denn während bei den bis jetzt gebräuchlichen Constructionen vor Eintritt der Condensation das erwärmte Wasser der Oberfläche und Dampf in die Druckkammer entweicht, wodurch dann eben die Condensation hervorgerufen wird, findet die Condensation bei dieser Construction nur infolge plötzlicher Verbreiterung der Oberfläche statt, ohne dafs die obere erwärmte Wasserschicht und Dampf entweichen kann.This has the purpose of steam savings; because while with the ones in use up to now Before condensation occurs, build the heated surface water and steam escapes into the pressure chamber, which then causes the condensation to take place the condensation in this construction only as a result of the sudden widening of the surface instead, without the upper heated water layer and steam being able to escape.
Bei der folgenden Druckperiode findet nun der Dampf, anstatt einer kalten Wasseroberfläche, eine angewärmte Schicht vor, und wird hierdurch sowie durch das Zurückhalten des Dampfes eine nicht unerhebliche Ersparnifs im Dampfverbrauch erzielt.During the following pressure period, instead of a cold water surface, the steam finds a warmed layer in front of it, and is thereby as well as by the holding back of the Steam achieved a not inconsiderable saving in steam consumption.
Noch ist zu bemerken, dafs zwei oder mehrere solcher Apparate zu gemeinschaftlicher Arbeit combinirt werden können.It should also be noted that two or more such apparatuses are used for collaborative work can be combined.
