Bei Naßluftpumpen der bekannten ArtWith wet air pumps of the known type
kann im Pumpenzylinder beim Hochgang des Kolbens ein Druck erzeugt werden, der gleich ist dem Kondensatordruck -p abzüglich der Wassersäule h und dem Ventilwiderstand r. a pressure can be generated in the pump cylinder when the piston goes up, which is equal to the condenser pressure -p minus the water column h and the valve resistance r.
Das VerhältnisThe relationship
gibt die mögliche Luftleere an.indicates the possible air void.
Gemäß der vorliegenden Erfindung werdenAccording to the present invention
ίο derartige Naßluftpumpen dadurch verbessert, daß im Pumpenzylinder oberhalb des höchsten bei normaler Fördermenge erreichten Wasserspiegels von Hilfssaugventilen beherrschte Lufteintrittsöffnungen vorgesehen sind. Hierdurch wird die Luftleere unabhängig von der Höhe der Wassersäule.ίο such wet air pumps thereby improved, that in the pump cylinder above the highest water level reached at normal delivery rate Air inlet openings controlled by auxiliary suction valves are provided. Through this the air void becomes independent of the height of the water column.
Eine Ausführungsform der Erfindung ist auf der Zeichnung schematisch dargestellt.
Der Pumpenzylinder α ist unten in bekannter Weise mit den Saugventilen b versehen,
durch die das Wasser vom Kondensator her durch die Leitung c eintritt, d sind die im
Kolben und e die im oberen Zylinderdeckel angeordneten Druckventile.An embodiment of the invention is shown schematically in the drawing.
The pump cylinder α is provided at the bottom in a known manner with the suction valves b through which the water from the condenser enters through line c, d are the pressure valves arranged in the piston and e are the pressure valves arranged in the upper cylinder cover.
Gemäß der vorliegenden Erfindung sindAccording to the present invention are
nun oberhalb des höchsten bei normaler Fördermenge erreichten Wasserspiegels Öffnungen f in der Zylinderwand angeordnet, die durch Hilfssaugventile g gegen die Wasserzuleitung c abgeschlossen sind. Openings f are now arranged in the cylinder wall above the highest water level reached with normal delivery, which are closed off from the water supply line c by auxiliary suction valves g.
Die Wirkung der Pumpe ist so, daß bei der Aufwärtsbewegung des Kolbens zunächst durch die Saugventile b das Wasser in die Pumpe eintritt. Sobald beim weiteren Aufwärtsgang der Kolben die Öffnungen f freigibt, tritt Luft durch die Saugventile g und die Öffnungen f in den Zylinder ein. Die Höhe der Wassersäule ist nunmehr auf die Saugwirkung des Kolbens ohne Einfluß. Die imThe action of the pump is such that when the piston moves upwards, the water first enters the pump through the suction valves b. As soon as the piston releases the openings f during further upward travel, air enters the cylinder through the suction valves g and the openings f. The height of the water column now has no effect on the suction effect of the piston. The in
Zylinder erreichbare Luftleere ist -——-der Ventilwiderstand der Hilfsventil ist.The air void that can be achieved in the cylinder is -— —- is the valve resistance of the auxiliary valve.
