Definitions
- the invention relates to a centrifugal pump for conveying liquids.
- Peripheral wheel centrifugal pumps have been known for a long time. With a peripheral wheel centrifugal pump, a high pressure at the outlet and thus a large delivery head can be achieved at a low delivery rate. However, the characteristic curves drop steeply, i.e. a significant increase in the delivery rate is only possible when the outlet pressure is greatly reduced, i.e. the achievable delivery head. The required pumping power also drops sharply.
- the characteristic curves of the radial centrifugal pumps which have also been known for a long time, are rather flat, i.e. a significant increase in the delivery rate can already be achieved by slightly reducing the outlet pressure in accordance with the achievable delivery head, while the required pump output increases slightly. However, the maximum outlet pressure that can be achieved is rather low.
- the invention is based on the object of specifying a centrifugal pump with which similarly high output pressures can be achieved as with a comparable peripheral centrifugal pump, the characteristics of which are, however, significantly flatter.
- the centrifugal pump according to the invention essentially corresponds to a peripheral wheel centrifugal pump, which has an extension on the inlet side, which has the features of a radial wheel centrifugal pump. It is very simple and space-saving and can be produced at a correspondingly low cost.
- the characteristics are qualitatively similar to those of a peripheral impeller centrifugal pump, but drop much less steeply.
- the pump power required slowly decreases as the delivery rate increases. A high degree of efficiency can be achieved.
- the centrifugal pump according to the embodiment according to the invention has ( Fig. 1 ) on a housing, which is composed of a front suction housing 1 and a rear pressure housing 2 connected to it by screws with spring washers 3, between which a circumferential seal 4 is arranged.
- the suction housing 1 and the pressure housing 2 are each approximately rotationally symmetrical and enclose an essentially rotationally symmetrical cavity with an outer annular space, the outer boundary of which is formed by peripheral parts of the suction housing 1 and the pressure housing 2 and which consists of a front annular space 5 and a rear annular space 6 exists.
- the front annular space 5 is connected to an inlet connector 7, which is attached centrally to the suction housing 1 and opens into the cavity at the front.
- the pressure housing 2 carries a peripherally arranged outlet connection 8, which leads approximately tangentially upwards out of the rear annular space 6 and whose clear cross section corresponds approximately to that of the inlet connection 7.
- An impeller 11 (see also FIG. 3) is mounted on a drivable drive shaft 10 guided through a mechanical seal 9 Fig. 2 where the suction housing 1 is omitted and 4a-c ) attached in the cavity in one direction (see arrow in Fig. 2 ) is rotatable about a central axis 12.
- the impeller 11 has a disk-shaped base, which carries webs 13 projecting vertically on a front side facing the inlet connection piece 7, which webs extend from the inside, that is to say bent back from near the axis in the running direction, towards the outer edge of the base, but with an edge region of the base The front remains free.
- the impeller 11 has radial webs 15 of the same height, which run radially from the inside, ie from an annular web 14 surrounding the axis 12 to the outer edge of the base, which are spaced from a rear wall of the pressure housing 2, so that there is an inside the space 16 adjoining the rear annular space 6 remains free.
- the webs can also protrude beyond the outer edge of the base.
- the distance between the ring web 14 and a rear wall of the pressure housing 2 is bridged by a fixed ring web 17 projecting therefrom against the ring web 14, such that there is only a narrow circumferential gap between the ring webs 14 and 17.
- the intermediate wall 18 has a recess 19 ', which has the shape of a Has circular sector, which extends from the inner edge of the intermediate wall 18 to close to its outer edge and occupies an angular range of approximately 45 ° and forms an annular sector-shaped passage 19.
- the area of the passage 19 corresponds approximately to the clear cross section of the outlet connection 8, any deviations are preferably at most 20%.
- the passage 19 is in the direction of rotation of the impeller 11, a lock 20 (s. Fig. 3 , where the suction housing 1, the impeller 11, the intermediate wall 18 and the shaft 10 are omitted) immediately ahead, which in turn closely follows the opening in the rear annular space 6, which leads into the outlet port 8.
- the lock 20 is designed as an approximately radial ledge projecting from the rear wall of the pressure housing 2, extending through the intermediate space 16 and the rear annular space 6 and interrupting it, which reaches close to the webs 15 of the impeller 11 and abuts the intermediate wall 18. Its front is slightly inclined outwards in the running direction, so that it leads continuously to the outlet connection 8.
- the shaft 10 is driven and the impeller 11 rotates in the example in Fig. 2 specified direction.
- the liquid to be transported is sucked in through the inlet connection 7 (arrow x in Fig. 1 . 2 ), carried along by the webs 13 on the front of the impeller 11 and pressed into the front annular space 5 by the centrifugal force.
- the liquid then gets into the rear annular space 6, where it is pressed inwards and partly between the webs 15 on the rear of the impeller 11 and into the intermediate space 16.
- the effect of the centrifugal pump according to the invention is similar to that of connecting a radial wheel centrifugal pump and a peripheral wheel centrifugal pump in series, but the structure is much simpler.
- the characteristics ( Fig. 6 ) lie approximately between the characteristics of these two known types of centrifugal pumps.
- the achievable outlet pressure and thus the maximum delivery head H is high, similar to a peripheral centrifugal pump.
- the outlet pressure, ie the delivery head H drops less rapidly with increasing delivery rate Q.
- the power requirement P does not depend very much on the delivery rate Q either.
- the characteristic curves are approximated to those of a radial wheel centrifugal pump.

Abstract
Die Erfindung betrifft eine Kreiselpumpe. Ein Gehäuse mit einem zentralen Eintrittsstutzen (7) und einem peripheren Austrittsstutzen (8) enthält ein Laufrad (11) mit an einer Vorderseite entgegen einer Laufrichtung zurückgebogenen Stegen (13) und an einer Rückseite radialen Stegen (15). Ein das Laufrad (11) umgebender Ringraum ist durch eine Zwischenwand (18) in einen vorderen Ringraum (5) und einen hinteren Ringraum (6), an den nach innen ein Zwischenraum (16) anschliesst, geteilt, die jedoch durch einen Durchlass (19) in der Zwischenwand (18) verbunden sind. Auf den Austrittsstutzen (8) folgt in Laufrichtung eine nahe an die Rückseite des Laufrades (11) heranreichende und an die Zwischenwand (18) stossende Sperre, die dem Durchlass (19) unmittelbar voraufgeht. Flüssigkeit wird durch den Eintrittsstutzen (7) angesaugt, gelangt in den vorderen Ringraum (5), dann durch den Durchlass (19) in den hinteren Ringraum (6), zwischen die Stege (15) und in den Zwischenraum (17). Sie wird von der Sperre in den Austrittstutzen (8) gelenkt. Die Kreiselpumpe weist verhältnismässig flache Kennlinien auf, ermöglicht aber einen hohen Ausgangsdruck.The invention relates to a centrifugal pump. A housing with a central inlet connection (7) and a peripheral outlet connection (8) contains an impeller (11) with webs (13) which are bent back against a running direction on a front side and radial webs (15) on a rear side. An annular space surrounding the impeller (11) is divided by an intermediate wall (18) into a front annular space (5) and a rear annular space (6), to which an intermediate space (16) adjoins on the inside, but is separated by a passage (19 ) are connected in the intermediate wall (18). The outlet connection (8) is followed in the running direction by a barrier which comes close to the rear of the impeller (11) and abuts the intermediate wall (18) and which immediately precedes the passage (19). Liquid is sucked in through the inlet connection (7), reaches the front annular space (5), then through the passage (19) into the rear annular space (6), between the webs (15) and into the intermediate space (17). It is directed by the lock into the outlet nozzle (8). The centrifugal pump has relatively flat characteristics, but enables a high outlet pressure.
Description
Die Erfindung betrifft eine Kreiselpumpe zur Förderung von Flüssigkeiten.The invention relates to a centrifugal pump for conveying liquids.
Peripheralrad-Kreiselpumpen sind seit langem bekannt. Mit einer Peripheralrad-Kreiselpumpe kann bei geringer Förderrate ein hoher Druck am Ausgang und damit eine grosse Förderhöhe erzielt werden. Die Kennlinien fallen allerdings steil ab, d.h. eine deutliche Zunahme der Förderrate ist nur bei starker Verminderung des Ausgangsdrucks, d.h. der erzielbaren Förderhöhe, möglich. Die erforderliche Pumpleistung fällt dabei ebenfalls steil ab. Bei den ebenfalls seit langem bekannten Radialrad-Kreiselpumpen sind die Kennlinien eher flach, d.h. eine deutliche Zunahme der Förderrate ist schon durch geringfügige Verringerung des Ausgangsdrucks, entsprechend der erzielbaren Förderhöhe, erzielbar, während die erforderliche Pumpleistung leicht ansteigt. Allerdings ist der erzielbare maximale Ausgangsdruck eher gering.Peripheral wheel centrifugal pumps have been known for a long time. With a peripheral wheel centrifugal pump, a high pressure at the outlet and thus a large delivery head can be achieved at a low delivery rate. However, the characteristic curves drop steeply, i.e. a significant increase in the delivery rate is only possible when the outlet pressure is greatly reduced, i.e. the achievable delivery head. The required pumping power also drops sharply. The characteristic curves of the radial centrifugal pumps, which have also been known for a long time, are rather flat, i.e. a significant increase in the delivery rate can already be achieved by slightly reducing the outlet pressure in accordance with the achievable delivery head, while the required pump output increases slightly. However, the maximum outlet pressure that can be achieved is rather low.
Der Erfindung liegt die Aufgabe zu Grunde, eine Kreiselpumpe anzugeben, mit der ähnlich hohe Ausgangsdrücke erzielt werden können wie mit einer vergleichbaren Peripheralrad-Kreiselpumpe, deren Kennlinien aber deutlich flacher sind.The invention is based on the object of specifying a centrifugal pump with which similarly high output pressures can be achieved as with a comparable peripheral centrifugal pump, the characteristics of which are, however, significantly flatter.
Diese Aufgabe wird durch die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, gelöst. Die erfindungsgemässe Kreiselpumpe entspricht im wesentlichen einer Peripheralrad-Kreiselpumpe, welche eingangsseitig eine Ergänzung aufweist, die Merkmale einer Radialrad-Kreiselpumpe hat. Dabei ist sie sehr einfach und platzsparend aufgebaut und entsprechend kostengünstig herstellbar.This object is achieved by the invention as characterized in the claims. The centrifugal pump according to the invention essentially corresponds to a peripheral wheel centrifugal pump, which has an extension on the inlet side, which has the features of a radial wheel centrifugal pump. It is very simple and space-saving and can be produced at a correspondingly low cost.
Die Kennlinien sind denen einer Peripheralrad-Kreiselpumpe qualitativ ähnlich, fallen aber wesentlich weniger steil ab. Insbesondere geht mit zunehmender Förderrate die erforderliche Pumpleistung langsam zurück. Es kann ein hoher Wirkungsgrad erzielt werden.The characteristics are qualitatively similar to those of a peripheral impeller centrifugal pump, but drop much less steeply. In particular, the pump power required slowly decreases as the delivery rate increases. A high degree of efficiency can be achieved.
