Hubluftpumpe. Patentiert im Deutschen Reiche vom 19. Juni 1901 ab. Lifting air pump. Patented in the German Empire on June 19, 1901.
Vorliegende Erfindung bezieht sich auf eine Hubluftpumpe, bei welcher die Bewegung des doppeltwirkenden Pumpenkolbens durch die auf jeder Seite desselben angeordneten einfach wirkenden Dampfkolben erfolgt; diese werden vorteilhaft mit dem Pumpenkolben aus einem Stück hergestellt und steuern in bekannter Weise Verteilungsschieber für die Ein- und Ausströmung des The present invention relates to a lifting air pump in which the movement of the double-acting pump piston by those arranged on each side of the same single-acting steam piston takes place; these are beneficial with the pump piston made from one piece and control in a known manner distribution slide for the inflow and outflow of the
ίο Dampfes. Der Flächenunterschied zwischen den kleinen Dampfzylindern und dem großen Luftzylinder ist bedingt durch den Unterschied des Druckes, welcher bei dem Dampf etwa zwischen 6 und io Atm. ausmachen kann und bei der Vakuumpumpe höchstens ι Atm. beträgt.ίο steam. The difference in area between the small steam cylinder and the large air cylinder is due to the difference of the pressure, which in the case of the steam is between 6 and 10 atm. turn off can and with the vacuum pump at most ι atm. amounts to.
Die neue Hubluftpumpe soll besonders für Oberflächenkondensation und für Vakuumtrockenvorrichtungen Verwendung finden.The new lifting air pump is said to be particularly suitable for surface condensation and for vacuum drying devices Find use.
Beiliegende Zeichnung stellt die doppeltwirkende Hubluftpumpe im Horizontalschnitt dar. Der Pumpenzylinder α ist in bekannter Weise mit Saugöffnungen b versehen, durch welche die Luft aus einem um die Mitte des Zylinders herumgelegten Kanal c, der mit dem zu evakuierenden Räume in Verbindung steht, abgesaugt werden soll.The accompanying drawing shows the double-acting lifting air pump in horizontal section. The pump cylinder α is provided in a known manner with suction openings b through which the air is to be sucked out of a channel c around the center of the cylinder, which communicates with the rooms to be evacuated .
In dem Pumpenzylinder α bewegt sich der Pumpenkolben d, welcher so breit ist, daß er am Ende eines jeden Hubes die Saugöffnungen b eben freigibt. Mit dem Pumpenkolben d sind die beiden Dampfkolben e e1 verbunden, die in den beiden Dampfzylindern ff1 geführt sind. Beide Kolben e el sind mit einer zentralen Bohrung g versehen, in welche eine mit einem Kopf h versehene Stange i eintreten kann, die mit ihrem anderen Ende an den Dampfverteilungsschieber angreift.In the pump cylinder α moves the pump piston d, which is so wide that it just releases the suction openings b at the end of each stroke. The two steam pistons ee 1 , which are guided in the two steam cylinders ff 1 , are connected to the pump piston d. Both pistons ee l are provided with a central bore g into which a rod i provided with a head h can enter, the other end of which engages the steam distribution slide.
In den Deckeln des Zylinders α sind Druckventile k k1 angeordnet, durch welche die angesaugte Luft hinausgepreßt wird.In the covers of the cylinder α pressure valves kk 1 are arranged, through which the sucked air is pressed out.
Die Arbeitsweise dieser doppeltwirkenden Luftpumpe ist folgende:This double-acting air pump works as follows:
Der Dampf tritt zunächst hinter den Dampfkolben e und bewegt denselben auswärts. Hierbei wird die vorher angesaugte, im Zylinder α befindliche Luft komprimiert und durch das Druckventil k1 hinausbefördert. Kurz bevor der Kolben d seine äußerste rechte Stellung erreicht, wird der Ansatz h der Stange i von einem Ansatz im Kolben e angeschlagen, und die Stange i wird mitgenommen, wobei sie den Dampfverteilungsschieber derart bewegt, daß derselbe auf freien Auspuff gestellt wird. Der Dampf kann infolgedessen aus dem Zylinder/ ausströmen.The steam first passes behind the steam piston e and moves it outwards. Here, the air previously sucked in and located in the cylinder α is compressed and conveyed out through the pressure valve k 1. Shortly before the piston d reaches its extreme right position, the extension h of the rod i is struck by a projection in the piston e , and the rod i is carried along, moving the vapor distribution slide in such a way that it is set to free exhaust. As a result, the steam can flow out of the cylinder /.
Bei der Auswärtsbewegung des Kolbens d hat der Dampfkolben e1 die Stange i mitgenommen und den zugehörigen Dampfverteilungsschieber auf Einströmung gestellt. Infolgedessen kann hinter den Dampf kolben el Dampf treten, so daß der Pumpenkolben dumkehren und die vorher bei seiner Auswärtsbewegung angesaugte Luft komprimieren und durch das Druckventil k hinausbefördern wird. Dieser Arbeitsvorgang wieder-During the outward movement of the piston d , the steam piston e 1 has taken the rod i with it and set the associated steam distribution slide to the inflow. As a result, steam can occur behind the steam piston e l , so that the pump piston d reverse and compress the air previously sucked in during its outward movement and is conveyed out through the pressure valve k. This work process again
holt sich bei jedem Kolbenhub. Es wird stets infolge des im Zylinder α befindlichen Vakuums durch die Saugöffnungen b Luft aus dem zu evakuierenden Räume angesaugt und diese Luft alsdann bei der Rückkehr des Kolbens durch die Druckventile hinausgedrängt. picks up with every piston stroke. As a result of the vacuum in the cylinder α, air is always sucked in from the space to be evacuated through the suction openings b and this air is then forced out through the pressure valves when the piston returns.
Es ist natürlich auch möglich, die Ansaugeöffnungen b durch in den Deckeln angebrachte Saugventile zu ersetzen.It is of course also possible to replace the suction openings b with suction valves fitted in the covers.
