Description
η.η.
Es ist bekannt, dafs bei einfach wirkenden Pumpen unter gewissen Umständen eine sogenannte »Mehrförderung« eintritt, wenn das zu fördernde Wasser eine grofse lebendige Kraft erlangt hat, d. h. bei einigen Pumpen kann das Saugventil während nur eines Theiles der Vorwärtsbewegung des Kolbens geschlossen werden, und dafs das Druckventil nur während eines Theiles der Saugbewegung geschlossen werden kann und dafs das Volumen der von der Pumpe geförderten Flüssigkeit das dem Kolbenweg entsprechende Volumen übersteigt.It is known that in the case of single-acting pumps, under certain circumstances a so-called "Additional pumping" occurs when the water to be pumping has a great living force has attained, d. H. in some pumps the suction valve can operate for only part of the time Forward movement of the piston can be closed, and that the pressure valve only during of a part of the suction movement can be closed and that the volume of the The liquid delivered by the pump exceeds the volume corresponding to the piston travel.
Bei der vorliegenden Tauchkolbenpumpe wird nun diese Mehrförderung in wirksamster Weise dadurch vergröfsert, dafs Saugrohr, Cylinder und Druckrohr möglichst in derselben Richtung liegen, so dafs der Widerstand, welcher dem durch die Pumpe strömenden Wasser entgegengesetzt wird, möglichst herabgemindert wird und dafs der Tauchkolben in der Förderrichtung des Wassers in den Cylinder hineintritt. Mittelst einer derartigen Pumpe kann man eine bedeutend gröfsere Wassermenge fördern als jene, welche dem Querschnitt und dem Hub des Kolbens sowie der Anzahl der Hübe desselben entspricht, so dafs eine Pumpe der vorliegenden Art unter sonst gleichen Verhältnissen dieselbe Leistung besitzt, wie eine drei- bis viermal gröfsere gewöhnliche Pumpe.With the present plunger piston pump, this additional delivery is now more effective Way enlarged by the fact that suction pipe, cylinder and pressure pipe in the same place as possible Direction, so that the resistance, which the water flowing through the pump is opposed, is reduced as possible and that the plunger in the conveying direction of the water enters the cylinder. One can use such a pump promote a significantly larger amount of water than that which the cross-section and the Stroke of the piston and the number of strokes of the same, so that a pump of the present species has the same performance as a Ordinary pump three to four times larger.
Eine derartige Pumpe ist auf der beiliegenden Zeichnung in zwei verschiedenen Ausführungsformen dargestellt.Such a pump is shown in two different embodiments in the accompanying drawing shown.
Das Saugrohr b schliefst sich nahe an dem Eintrittspunkt des Tauchkolbens d in den Cylinder α in einer solchen Curve an denselben an, dafs das einströmende Wasser keine wesentliche Richtungsänderung erleidet. In derselben Weise schliefst sich das Druckrohr c, in welchem das Druckventil e angeordnet ist, an den Cylinder α an. Wenn das Wasser eine gewisse lebendige Kraft erlangt hat, wird es, wenn die Pumpe in Thätigkeit ist, aus dem Saugrohr b in den Cylinder α und aus diesem in das Druckrohr c fliefsen, und zwar während der Zeit, in welcher der Kolben seine Bewegung nach innen bewirkt, seine Bewegungsrichtung wechselt und auch noch während einer Zeit seiner . nach aufsen gerichteten Bewegung. Die Querschnitte der Pumpe werden so gewählt, dafs die Eintrittsöffnung in den Cylinder, der Zwischenraum zwischen dem Tauchkolben und der Cylinderwandung und die Austrittsöffnung ganz oder nahezu den gleichen Querschnitt haben. Unter Umständen kann das Saugrohr einen grofseren Querschnitt haben als das Druckrohr.The suction pipe b adjoins the cylinder α close to the entry point of the plunger d in such a curve that the inflowing water does not undergo any significant change in direction. In the same way, the pressure pipe c, in which the pressure valve e is arranged, connects to the cylinder α . When the water has acquired a certain vital force, when the pump is in operation, it will flow from the suction pipe b into the cylinder α and from this into the pressure pipe c during the time in which the piston is following its movement causes inside, changes its direction of movement and also during a time of its. outward movement. The cross-sections of the pump are chosen so that the inlet opening into the cylinder, the space between the plunger and the cylinder wall and the outlet opening have completely or almost the same cross-section. Under certain circumstances, the suction pipe can have a larger cross-section than the pressure pipe.
Wenn die Pumpe das Wasser nicht ansaugt, dieses vielmehr der Pumpe zufiiefst, kann das Druckventil ganz fortgelassen werden. In diesem Falle werden in dem Cylinder bezw. dem Saug- und Druckrohr oder beiden Taschen oder Vertiefungen f angebracht, welche dem Wasser in der Förderrichtung einen nur geringen, in der entgegengesetzten Richtung dagegen einen erheblichen Widerstand entgegensetzen. Ebenso kann der .Kolben mit ähnlichen Taschen oder Vertiefungen g versehen werden. Die Zahl der Taschen oderIf the pump does not suck in the water, but instead feeds it to the pump, the pressure valve can be omitted entirely. In this case bezw in the cylinder. attached to the suction and pressure pipe or both pockets or depressions f , which oppose only a slight resistance to the water in the conveying direction and a considerable resistance in the opposite direction. Likewise, the .Kolben can be provided with similar pockets or recesses g . The number of pockets or
Vertiefungen kann geändert werden je nach den an die Pumpe gestellten Anforderungen, und ist so zu bemessen, dafs ein Zurückfliefsen des Wassers thunlichst verhindert wird.Depressions can be changed depending on the requirements placed on the pump, and is to be measured in such a way as to prevent the water from flowing back as far as possible.
