Abstract
The utility novel discloses a conical impeller pump, which comprises a pump body and a impeller shaft rotationally mounted on the pump body, wherein an impeller is mounted on an impeller segment in the pump body; the pump body is provided with a liquid inlet pipe and a liquid outlet pipe which are communicated with an inner cavity of the pump body; the inner cavity surface of the pump body is frustum-shaped; the liquid inlet pipe is communicated with the end (with a larger diameter) of an inner cavity of the pump body; the liquid outlet pipe is communicated with the end (with a smaller diameter) of the inner cavity of the pump body; the outer surface of the impeller is adapted to the inner cavity surface of the pump body; and the impeller is uniformly distributed on the surface of the impeller shaft in a spiral and surrounding manner. As fluid is spirally ejected in the axial direction, the reflux resistance of the fluid is reduced, and the energy conversion efficiency is improved; and the conical impeller pump has the advantage and effect of low energy consumption.
Description
Technical field
The utility model relates to a kind of disk of conical profile pump.
Background technique
Flow direction according to fluid in wing pump, existing wing pump mainly are divided into radial-flow type, diagonal flow type, aial flow impeller pump.Use this wing pump when transmitting fluid, impeller can be subject to the resistance of anti-effluent fluid in the pump housing, so the efficient of transformation of energy is low, and its defective is exactly that wing pump power is large, conveying capacity is low.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of disk of conical profile pump that can reduce the anti-flow resistance of fluid.
For solving the problems of the technologies described above, the disk of conical profile pump that provides comprises the pump housing and is rotatably installed in impeller shaft on the pump housing, be positioned on the pump housing impeller shaft section impeller is housed, the liquid inlet pipe and the drain pipe that are communicated with its inner chamber are housed on the pump housing, its structural feature is: the inner cavity surface of the pump housing is cone table shape, the end UNICOM that described liquid inlet pipe and pump housing intracavity diameter are large, the end UNICOM that drain pipe and pump housing intracavity diameter are little, the outer surface of impeller and the inner cavity surface of the pump housing adapt, and impeller evenly is periphery in the shape of a spiral on the impeller shaft surface.
After adopting said structure, with fluid in liquid inlet pipe enters the pump housing, impeller shaft and power plant are in transmission connection, and the rotation of impeller shaft when rotation impeller is because impeller surface and pump housing inner cavity surface adapt, thereby impeller surface also becomes cone table shape, fluid enters from the large end of impeller diameter, and under the whipping of spiral helicine impeller, fluid can spray in the shape of a spiral, an end little from impeller diameter enters in drain pipe, thereby realizes the fluid conveying.
In sum, because fluid is helical ejection vertically, thereby reduce the anti-flow resistance of fluid, improved energy conversion efficiency, the utlity model has the low advantageous effect of power consumption.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is along the sectional drawing of A-A line in Fig. 1.
Embodiment
Disk of conical profile pump as shown in the drawing, it comprises the pump housing 1 and is rotatably installed in impeller shaft 5 on the pump housing 1, be positioned on 5 sections of the pump housing 1 impeller shafts impeller 2 is housed, the liquid inlet pipe 3 and the drain pipe 4 that are communicated with its inner chamber are housed on the pump housing 1, the inner cavity surface of the pump housing 1 is cone table shape, the end UNICOM that liquid inlet pipe 3 and the pump housing 1 intracavity diameter are large, the end UNICOM that drain pipe and the pump housing 1 intracavity diameter are little, the inner cavity surface of the outer surface of impeller 2 and the pump housing 1 adapts, and impeller 2 evenly is periphery in the shape of a spiral on impeller shaft 5 surfaces.In actual production, this impeller shaft 5 can be one-body molded with impeller 2, and perhaps the pto＝power take-off of impeller shaft 5 use power plant replaces.
During use, rear end and the power plant of impeller shaft 5 are in transmission connection, liquid inlet pipe 3 is connected on input duct, drain pipe 4 is connected on the fluid pipeline, start power plant, can realize the transmission of fluid.The acceleration that the utility model is particularly suitable for liquid transmits.
