Abstract

The utility model relates to a high efficiency and high pressure energy-saving fluid conveyor, which is characterized in that a centrifugal running impeller, a centrifugal fixed impeller and an annular diversion channel are coaxially positioned in a volute. The running impeller is positioned in the center and a running impeller shaft is connected with a power input shaft. The running impeller vanes are distributed equally on the circle. A fluid inlet lies beside the center while the annular diversion channel lies on the periphery. A fluid outlet is positioned on the periphery of the annular diversion channel while the fixed impeller is positioned between the annular diversion channel and the running impeller. As the fixed impeller vanes set aslant in the direction of fluid flowing is equally distributed on the circle, a booster cavity of the fixed impeller is formed to divide the fluid. The widths of the vanes of the two impellers are perfectly matched in the joint and a clearance fit is thus formed between the two impellers. The utility model has the advantages of avoiding reflux effectively, improving remarkably conveying efficiency of the fluid and increasing conveying pressure finally for the purpose of energy saving.

Description

The energy-saving fluid conveyer of efficient high-pressure

Technical field:

The utility model relates to fluid delivery system.

Background technique:

Fluid delivery system such as blower fan, water pump is all used in various industries to some extent.The structural type that is adopted is that wheel rotor is set in spiral case, is transferred fluid from axially entering spiral case, obtains centrifugal force under the effect of impeller, and this centrifugal force tangentially throws away it in the spiral case outlet.

At this structural type, may in spiral case, form backflow owing to be transferred fluid, thereby in actual the use, the FLUID TRANSPORTATION loss of this form is quite big.

Summary of the invention:

The utility model is for avoiding above-mentioned existing in prior technology deficiency, providing a kind of efficient high-pressure energy-saving fluid conveyer.

The technological scheme that the utility model technical solution problem is adopted is:

The utility model adopts centrifugal structure, it is characterized in that the coaxial centrifugal movable vane wheel that is provided with in spiral case, decide impeller and annular guide channel, described movable vane wheel is positioned at the center, movable vane wheel wheel shaft and power input shaft shaft coupling, the movable vane impeller blade is evenly distributed on the circumference, its center sidepiece is a fluid input, the annular guide channel is positioned at periphery, periphery at annular guide channel is provided with fluid output, decide impeller between annular guide channel and movable vane wheel, it is described that to decide impeller be to be evenly distributed on the circumference by the impeller blade of deciding that respectively is obliquely installed on fluid flow direction, formation is decided the impeller chamber of boosting to what rotating fluid was cut apart, described to decide impeller blade corresponding consistent in its connecting part with movable vane impeller blade width, decides to form Spielpassung between impeller and the movable vane wheel described.

Structural feature of the present utility model is that also described movable vane impeller blade is disposed radially, or is obliquely installed, or adopt composite structure, described composite structure be inner ring at its movable vane impeller blade for being obliquely installed, the outer ring is for being disposed radially.

Compared with the prior art, the beneficial effects of the utility model are embodied in: in the utility model, rotate the rotation of drive fluid by the movable vane wheel, the fluid of rotation boosts in face of cutting apart of its flow direction through deciding impeller, effectively avoid refluxing, significantly improve transfer efficiency, increase discharge pressure, thereby reach energy-conservation purpose.

Description of drawings:

Fig. 1 is the utility model structural representation.

Fig. 2, Fig. 3 are the utility model different structure form schematic representation.

Fig. 4, Fig. 5, Fig. 6 are the different mode of execution structural representations of the utility model.

Number in the figure: 1 spiral case, 2 movable vanes wheel, 3 is decided impeller, 4 annular guide channels, 5 movable vane impeller blades, 6 fluid outputs, 7 and is decided impeller blade, 8 fluid inputs, 9 power input shafts.

Below by embodiment the utility model is further described:

Embodiment:

Referring to Fig. 1, Fig. 2 and Fig. 3, present embodiment adopts centrifugal structure, and the coaxial movable vane that is provided with is taken turns 2, decided impeller 3 and annular guide channel 4 in spiral case 1.

Shown in the figure, what prior art was identical is, movable vane wheel 2 is positioned at the center, movable vane wheel wheel shaft and power input shaft 9 shaft couplings, and movable vane impeller blade 5 is evenly distributed on the circumference, and its center sidepiece is a fluid input 8.

In the present embodiment, annular guide channel 4 is positioned at periphery, periphery at annular guide channel 4 is provided with fluid output 6, decide impeller 3 between annular guide channel 4 and movable vane wheel 2, deciding impeller 3 is to be evenly distributed on the circumference by the impeller blade 7 of deciding that respectively is obliquely installed on fluid flow direction, formation is decided the impeller chamber of boosting to what rotating fluid was cut apart, and it is corresponding consistent in its connecting part with the width of movable vane impeller blade 5 to decide impeller blade 7, is deciding to form Spielpassung between impeller 3 and the movable vane wheel 2.

In concrete the enforcement, spiral case 1 is respectively arranged with volute inlet and spiral case outlet, decides impeller 3 and fixedlys connected with spiral case 1, also can be set to overall structure with spiral case 1 with deciding impeller 3.Movable vane wheel 2 and decide impeller 3 and have totally-enclosed and semiclosed two kinds of forms, in order to obtain better intensity and hardness, can adopt totally enclosed form, movable vane impeller blade 5 can be disposed radially as shown in Figure 2, also can be shown in Figure 1 being obliquely installed, can also have the complex form of Fig. 1 and Fig. 2, promptly at the inner ring of movable vane impeller blade 5 for being obliquely installed, the outer ring is for being disposed radially, as shown in Figure 3.

In order further to raise the efficiency, the matching gap that is arranged between the inlet of the inlet of spiral case 1 and movable vane wheel 2 needs as far as possible little, the matching gap that is arranged on the outlet of movable vane wheel and decides between the impeller eye also needs as far as possible little, the excircle of movable vane wheel 2 and the inner circumference of deciding impeller 3 necessary basically identical on width, and be oppositely arranged, reduce the fluid that throws away in the movable vane wheel as far as possible and produce backflow, so can guarantee to decide impeller and can accept the fluid of taking turns well from movable vane because of having pressure.

The utility model can be widely used in the lifting pump shown in Figure 4, or in the self-priming pump shown in Figure 5, or in the submersible pump shown in Figure 6, among the figure, movable vane wheel wheel shaft and power input shaft 9 shaft couplings.

In the present embodiment, Fig. 1, Fig. 2 and Figure 3 shows that the tactic pattern schematic representation of blower fan; Fig. 4, Fig. 5 and Fig. 6 are the pump structure schematic representation.
