Abstract
The utility model discloses a non-sweep angle conical variable pitch inducer which relates to a liquid pump inducer; a spiral vane is arranged on a hub; the spiral vane is a non-sweep angle conical variable pitch vane; the shape of the outer edge of the inducer formed by the vane is of a conical shape; as the spiral vane is a non-sweep angle conical variable pitch inducer and the shape of the outer edge of the inducer formed by the vane is of a conical shape with a non-sweep angle of Delta Beta, the inlet end of the non-sweep angle is on the same coaxial surface, the non-sweep angle conical variable pitch inducer has the advantages of easy adjusted inlet angle and outlet angle, good anti-cavitation, smaller coaxial structural size, less material consumption, and low cost. Moreover, the non-sweep angle conical variable pitch inducer is suitable for liquid pumps.
Description
Technical field
The present invention relates to the liquid pump inducer, say it is a kind of no sweepback pyramid Variable-pitch Inducers in detail.
Background technique
Existing liquid pump inducer, be on wheel hub, to be provided with the uniform pitch helical blade, after helical blade entrance point radius increases progressively several angle Δ β gradually, its radius equals outlet end outer rim radius, Δ β is called the sweepback angle, entrance point is not on same axial plane, and the inducer outer rim that blade is formed is shaped as cylindrical.This liquid pump inducer, because after helical blade entrance point radius increases progressively several angle Δ β gradually, its radius equals outlet end outer rim radius, have sweepback angle Δ β, entrance point is not on same axial plane, and inlet blade angle and exit angle are difficult for adjusting, anti-cavitation performance is poor, the axial arrangement size is bigger, and consume material is many, the cost height.
Summary of the invention
The technical problem that the present invention solves is, solves blade and has sweepback angle Δ β, and entrance point is not on same axial plane, inlet blade angle and exit angle are difficult for adjusting, and anti-cavitation performance is poor, and the axial arrangement size is bigger, consume material is many, and the problem that cost is high provides a kind of no sweepback angle Δ β, entrance point is on same axial plane, inlet blade angle and exit angle are easily adjusted, and anti-cavitation performance is good, and the axial arrangement size is less, consume material is few, the no sweepback pyramid Variable-pitch Inducers that cost is low.
Technological scheme of the present invention is, is provided with helical blade on wheel hub, and the main structure characteristics are, helical blade is the taper variable-pitch blade at no sweepback angle, and the inducer outer rim of blade composition is shaped as taper.
The invention has the beneficial effects as follows, because helical blade is the taper variable-pitch blade at no sweepback angle, the inducer outer rim that blade is formed is shaped as taper, no sweepback angle Δ β, entrance point is on same axial plane, and inlet blade angle and exit angle are easily adjusted, anti-cavitation performance is good, the axial arrangement size is less, and consume material is few, and cost is low.The present invention is applicable to liquid pump.
Description of drawings
Fig. 1, Fig. 2, Fig. 3 are a kind of structural representations of the present invention, also are a kind of embodiment's schematic representation; Fig. 1 is a plan view of the present invention, plane figure of the present invention during Fig. 2, runner of the present invention axis projection during Fig. 3.
Embodiment
No sweepback pyramid Variable-pitch Inducers as shown in the figure, wheel hub 1 is provided with helical blade 2, and as can be seen from the figure, wheel hub 1 is provided with two blades.Helical blade 2 is the taper variable-pitch blade at no sweepback angle, the inducer outer rim that blade is formed is shaped as taper, because helical blade 2 is the taper variable-pitch blade at no sweepback angle, the inducer outer rim that blade is formed is shaped as taper, no sweepback angle Δ β, entrance point is on same axial plane, blade 2 inlet angles and exit angle are easily adjusted, and anti-cavitation performance is good, and the axial arrangement size is less, consume material is few, and cost is low.The inlet angle of adjusting blade is littler, exit angle more greatly, can improve the anti-cavitation ability of inducer itself, the fluid lift of minimum simultaneously axial dimension generation maximum.
Claims (1)
1. no sweepback pyramid Variable-pitch Inducers, wheel hub is provided with helical blade, it is characterized in that, and helical blade is the taper variable-pitch blade at no sweepback angle, and the inducer outer rim of blade composition is shaped as taper.
