Abstract
The invention discloses a conical impeller pump. The conical impeller pump comprises a pump body and an impeller shaft which is rotationally arranged on the pump body, wherein impellers are arranged on an impeller shaft section positioned in the pump body; a liquid inlet pipe and a liquid outlet pipe which are communicated with the cavity of the pump body are arranged on the pump body; the inner cavity surface of the pump body is in the shape of a frustum; the liquid inlet pipe is communicated with the end, with larger diameter, of the cavity of the pump body; the liquid outlet pipe is communicated with the end, with smaller diameter, of the cavity of the pump body; the outer surfaces of the impellers are adapted to the inner cavity surface of the pump body; and the impellers are spirally, uniformly and annularly distributed on the surface of the impeller shaft. The fluid is sprayed spirally along the axis direction, so that the backstreaming resistance of the fluid is reduced; the energy conversion efficiency is improved; and the conical impeller pump has the advantage of lower energy consumption.
Description
Technical field
The present invention relates to a kind of disk of conical profile pump.
Background technique
According to the flow direction of fluid in wing pump, existing wing pump mainly is 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.
Summary of the invention
The technical problem to be solved in the present invention provides 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 impeller rotation during the impeller shaft rotation 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 the drain pipe, thereby realizes the fluid conveying.
In sum, because fluid is vertically helical ejection, thereby has reduced the anti-flow resistance of fluid, improved energy conversion efficiency, the present invention has the low advantageous effect of power consumption.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing:
Fig. 1 is structural representation of the present invention;
Fig. 2 is along the sectional drawing of A-A line among 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 is large with the pump housing 1 intracavity diameter, 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 the 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 usefulness 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 the input duct, drain pipe 4 is connected on the fluid pipeline, start power plant, can realize the transmission of fluid.The acceleration that the present invention is particularly suitable for liquid transmits.
