摘要:
Die Erfindung betrifft eine Doppelpumpe (1) mit einem Pumpengehäuse (2) umfassend eine erste Gehäuseseite (2a) mit einer ersten Pumpenkammer (16a) für das Laufrad einer ersten Kreiselpumpe, und eine zweite Gehäuseseite (2b) mit einer zweiten Pumpenkammer (16b) für das Laufrad einer zweiten Kreiselpumpe, wobei die Laufradachsen (9a, 9b) der ersten und zweiten Kreiselpumpe parallel nebeneinander liegen. Eine Isolierverkleidung (10, 20, 30) umgreift das Pumpengehäuse (2) umfassend ein erstes Isolierelement (10), das die erste Gehäuseseite (2a) zumindest teilweise umgreift und aus einer ersten Fügerichtung (A) radial zur Laufradachse (9a) der ersten Kreiselpumpe angeordnet ist, ein zweites Isolierelement (20), das die zweite Gehäuseseite (2b) zumindest teilweise umgreift und aus einer zur ersten entgegengesetzten zweiten Fügerichtung (B) radial zur Laufradachse (9b) der zweiten Kreiselpumpe angeordnet ist, und wenigstens ein drittes Isolierelement (30), das am Pumpengehäuse (2) aus einer dritten, parallel zu den Laufradachsen (9a, 9b) liegenden Fügerichtung (C) räumlich zwischen einer mechanischen Schnittstelle (15a) einer Antriebseinheit der ersten Kreiselpumpe zum Pumpengehäuse (2) und einer mechanischen Schnittstelle (15b) einer Antriebseinheit der zweiten Kreiselpumpe zum Pumpengehäuse (2) angeordnet ist. Die Erfindung betriff ferner ein Verfahren zur Montage der Isolierverkleidung (10, 20, 30).
摘要:
A pumping system for carbon dioxide applications comprises a plurality of centrifugal pumps each provided with one or more dry gas seals, and one or more barrier fluid delivery circuits for fluidly connecting the pump discharge of a pump in a running condition to at least one dry gas seal of another pump in standby condition. The pumps of the pumping system may be switched between a running condition and a standby condition through a control unit.
摘要:
A multi-pump apparatus includes a first component in a fluid heat transfer system, such as a heat exchanger, the first component including a body portion forming a first interface surface. A pumping component includes a second interface surface. The first and second interface surfaces are planar and combine to define two pump cavities and a planar interface groove supporting a seal ring that extends around the two pump cavities to prevent leakage of fluid from the pump cavities. The pumping component includes a pump impeller in each of the pump cavities and independently-controlled separate motors driving the two pump impellers using an on-board circuit board. One of the first and second components also defines a fluid inlet to and a fluid outlet from each of the pump cavities. Related methods are also defined.
摘要:
A pump assembly (1, 5, 6, 6') includes a plurality of pumps (10, 20, 30, 40, 50, 60). Each of the pumps (10, 20, 30, 40, 50, 60) includes a pump body (100, 500), a first opening (102, 502), a second opening (104, 504), a first connecting member (106, 506) and a second connecting member (108, 508). The first opening (102, 502) and the second opening (104, 504) are located at a periphery of the pump body (100, 500). The first connecting member (106, 506) is disposed on the first opening (102, 502) and the second connecting member (108, 508) is disposed on the second opening (104, 504). The first connecting member (106, 506) of one of the pumps (10, 20, 30, 40, 50, 60) is detachably connected to the second connecting member (108, 508) of another of the pumps (10, 20, 30, 40, 50, 60), such that each of the pumps (10, 20, 30, 40, 50, 60) can be connected to any of the pumps (10, 20, 30, 40, 50, 60).
摘要:
A discharge head for a vertical pump is proposed comprising a base plate (11) for mounting the discharge head, a top plate (12), at least one support member (13) connecting the base plate (11) with the top plate (12), a discharge pipe (15) with an outlet (16) for delivering a fluid, said discharge pipe (15) extending through the base plate (11), and an inner tube (17) for receiving a shaft (4) that connects a drive unit (3) with an impeller (21) of the vertical pump, wherein the inner tube (17) extends in an axial direction (A) and coaxially within the discharge pipe (15) in the region of the base plate (11), passes through a wall of the discharge pipe (15) at an intersection (18), and further extends to the top plate (12), wherein the inner tube (17) comprises a bellows member (19) being located between the intersection (18) and the top plate (12). In addition, a vertical pump with such a discharge head (10) is proposed
