Abstract
The utility model provides a divertor spiral case combination formula bilobed wheel centrifugal pump, the bilobed wheel centrifugal pump includes the pump body, pump cover, first order impeller, second level impeller, divertor and spiral case formula pumping chamber, the pump cover sets up on the pump body, first order impeller, second level impeller, divertor and spiral case formula pumping chamber set up inside the pump body, first order impeller and second level impeller pass through the divertor and link to each other, second level impeller sets up in spiral case formula pumping chamber. The utility model discloses having better energy transition effect and making the water conservancy performance index and the efficiency of pump improve greatly, simultaneously maximum flow and the biggest lift all have and improve by a relatively large margin.
Description
[technical field]
This utility model relates to a kind of double-impeller centrifugal pump, particularly to a kind of air deflector spiral case combination type double-impeller centrifugal pump.
[background technology]
The double-impeller centrifugal pump of existing production is as shown in Figure 1, the pump housing 1 ' is provided with a pump cover 2 ', it is provided with first order impeller 3 ' and second level impeller 4 ', the outlet of described first order impeller 3 ' and the import of second level impeller 4 ' in the pump housing back-to-back and crosses the connection of diffusion type transition runner 5 ' by one.
This product all adopts the organization plan that 2 grades of impellers are arranged back-to-back, first order impeller 1 ' to be exported between second level impeller 2 ' import either directly through the connection of diffusion type transition runner 5 ', it does not have design realizes the pumping chamber that kinetic energy is changed to pressure energy. Therefore have the disadvantage in that
The hydraulic performance of pump is poor, and the efficiency of pump is relatively low. Reason is to export high-velocity flow out from first order impeller 3 ', enters second level impeller 4 ' import either directly through diffusion type transition runner 5 ', and insufficient owing to spreading, kinetic energy is not fully converted to pressure energy, and pump lift is relatively low; Meanwhile, the divergence loss of high-velocity flow, all relatively larger along journey hydraulic loss, pump inefficient.
[summary of the invention]
The technical problems to be solved in the utility model, it is in that to provide a kind of air deflector spiral case combination type double-impeller centrifugal pump, it has good energy conversion effect and hydraulic performance index and the efficiency of pump is greatly improved, and maximum stream flow and H-Max all have a more substantial increase simultaneously.
This utility model is achieved in that
A kind of air deflector spiral case combination type double-impeller centrifugal pump, described double-impeller centrifugal pump includes the pump housing, pump cover, first order impeller, second level impeller, air deflector and scroll casing type pumping chamber, described pump cover is arranged on the pump housing, described first order impeller, second level impeller, air deflector and scroll casing type pumping chamber are arranged on pump body, described first order impeller is connected by air deflector with second level impeller, and described second level impeller is arranged in scroll casing type pumping chamber.
The utility model has the advantage of:
This utility model is the pumping chamber of flow-guiding device structure first order impeller, second level impeller Transition Design, both having maintained the advantage that double-impeller centrifugal pump configuration is compact, good energy conversion effect in turn ensure that product has higher hydraulic performance index and the efficiency of pump.Under same match power, maximum stream flow of the present utility model and H-Max all have a more substantial increase than existing product, the efficiency of pump of the present utility model improves about 5%～15% than existing product, Unit Weight of the present utility model reduces about 5%～10% than original product simultaneously, therefore this utility model energy-saving material-saving effect is obvious, and product cost promotes substantially.
[accompanying drawing explanation]
This utility model is further described with reference to the accompanying drawings in conjunction with the embodiments.
Fig. 1 is existing double-impeller centrifugal pump structure schematic diagram.
Fig. 2 is this utility model one air deflector spiral case combination type double-impeller centrifugal pump structure schematic diagram.
[detailed description of the invention]
Refer to shown in Fig. 2, embodiment of the present utility model is described in detail.
As shown in Figure 2, a kind of air deflector spiral case combination type double-impeller centrifugal pump involved by this utility model, described double-impeller centrifugal pump includes the pump housing 1, pump cover 2, first order impeller 3, second level impeller 4, air deflector 5 and scroll casing type pumping chamber 6, described pump cover 2 is arranged on the pump housing 1, it is internal that described first order impeller 3, second level impeller 4, air deflector 5 and scroll casing type pumping chamber 6 are arranged on the pump housing 1, described first order impeller 3 and second level impeller 4 are joined end to end by air deflector 5, and described second level impeller 4 is arranged in scroll casing type pumping chamber 6.
The high-velocity flow of first order impeller 3 outlet, (air deflector: compact conformation, energy conversion effect is better for the inter-stage pumping chamber being separated out by air deflector 5 and peripheral space. ) kinetic energy (speed energy) is converted to pressure energy entrance second level impeller 4; After second level impeller 4, design scroll casing type pumping chamber 6, can at utmost improve the hydraulic performance of pump.
This utility model is the pumping chamber of flow-guiding device structure first order impeller 3, second level impeller 4 Transition Design, both having maintained the advantage that double-impeller centrifugal pump configuration is compact, good energy conversion effect in turn ensure that product has higher hydraulic performance index and the efficiency of pump. Under same match power, maximum stream flow of the present utility model and H-Max all have a more substantial increase than existing product, the efficiency of pump of the present utility model improves about 5%～15% than existing product, Unit Weight of the present utility model reduces about 5%～10% than original product simultaneously, therefore this utility model energy-saving material-saving effect is obvious, and product cost promotes substantially.
Although the foregoing describing detailed description of the invention of the present utility model; but those familiar with the art is to be understood that; we are merely exemplary described specific embodiment; rather than for the restriction to scope of the present utility model; those of ordinary skill in the art, in the equivalent modification made according to spirit of the present utility model and change, should be encompassed in scope of the claimed protection of the present utility model.
