Abstract
The utility model relates to a centrifugal pump assembly with accelerating and multi-phase fluid separating transport, comprising an impeller. A channel is disposed in the impeller along the center line of the impeller, and is called an impeller longitudinal channel. Another channel is communicated between at least one overflowing groove channel and an impeller longitudinal channel, and is called an impeller radial channel. Compared with an outlet of the impeller radial channel, an inlet of the impeller radial channel is more away from the position of the impeller center line. A conducting hole is disposed in at least one impeller, adjacent to the overflowing groove channel. A rotating shaft is fixedly connected to the center of the impeller. A channel is disposed at one end of the rotating shaft connected to the impeller along the axial direction of the rotating shaft, and is called a rotating shaft channel. An inlet of the rotating shaft channel is communicated with an outlet of the impeller radial channel, and an outlet of the rotating shaft channel is disposed on the sidewall of the rotating shaft channel. A bump of the assembly is more suitable for bumping three-phase slurry including gas, liquid, and solid having a large amount of gas. Accordingly, multi-phase fluid separating transport can be accelerated, conveying efficiency of the bump can be greatly improved, and energy-saving effect is obvious.

Fig. 1 is the overall schematic of the utility model one embodiment's shaft, impeller and other part combination, and the part is sectional view.
Fig. 2 is that the A-A of impeller among Fig. 1 is to sectional view.
Embodiment
The utility model is described in further detail below in conjunction with embodiment, accompanying drawing.
In Fig. 1, the utility model one embodiment shown in Figure 2, accelerate heterogeneous fluid and separate the centrifugal pump assembly of carrying, include impeller 1, in impeller, along the impeller centerline direction passage is arranged, be called impeller vertical passage 2, in impeller, there is in addition impeller radial passage 3 to be communicated with between the overcurrent conduit 4 and impeller vertical passage 2 of impeller, and the import 5 of the impeller radial passage that communicates with described overcurrent conduit is positioned at further from the position of impeller center line than the outlet 6 of impeller radial passage, at blade 22 via 23 is arranged; Other has rotating shaft 7 to be fixedly connected on the center of impeller 1, at an end of the rotating shaft that links to each other with impeller, along the shaft axis direction passage is arranged, be called rotating shaft passage 8, and the import 9 of rotating shaft passage is connected with the outlet 6 of impeller radial passage, the outlet 10 of rotating shaft passage is positioned on the sidewall of rotating shaft passage; Near the import 5 that is positioned at the impeller radial passage, be provided with centrifugal valve 11; Be connected with two seal rings 12 in rotating shaft, 13, leave certain gap 14 between described two seal rings, be provided with pump case 15 in the periphery of impeller, pump case includes material feeding mouth 16, discharge port 17 and back shroud 18, the other parts fixed seal connection of back shroud and pump case, be provided with short tube 19 near the back shroud, seal ring 12,13 are within the short tube 19, and be fixedly connected with short tube, side ancient piece of jade, round, flat and with a hole in its centre at the short tube 19 corresponding with gap 14 has through hole 20, the outlet 10 of rotating shaft passage adopts dynamic seal apparatus 21 to be connected between gap 14 between rotating shaft 7 and the back shroud 18.
The present embodiment in use, need discharge port 17 temporary closes of pump case, and the power plant of being joined by other connect and drive rotating shaft 7 rotations, centrifugal valve 11 can be in greatly open mode because of centrifugal force, also to cooperate air extractor to bleed from through hole 20, like this, can produce suction force because of negative pressure near the import 5 of impeller radial passage, air pressure in the pump case 15 is reduced, so that the material feeding mouth 16 of pump case pumping fluid continuously, and flow in the overcurrent conduit of impeller 1, if contain simultaneously gas in the above-mentioned fluid, liquid, solid, then heavy solid and liquid constituent are subjected to be transported to far above above-mentioned suction force because of the centrifugal force that obtains after the impeller propelled outer rim of impeller, and finally discharge and carry from the discharge port 17 of the pump case opened subsequently; Although and the very little gas componant of proportion also is subjected to impeller propelled, but wherein the overwhelming majority is inhaled in the impeller radial passage 3 less than above-mentioned suction force because of the centrifugal force that obtains, by by force with solid and liquor separation, and finally carried separately through rotating shaft passage 8 and air extractor and discharged; Via 23 can make contiguous overcurrent conduit be connected, and makes the interior gas of described overcurrent conduit be sucked simultaneously power and takes away and shunt; Because of most gases because of the little separated independent conveying of proportion, can be so that impeller carries the efficient of all the other fluids that mainly contain liquid and solid to increase substantially, remarkable energy saving, delivery pressure also can improve because of the remarkable minimizing of carrying bubbles volume in the liquid secretly, and the difference transporting velocity of liquid, solid and gas all can be accelerated.
