Abstract
The invention discloses an axial flow pump impeller with sweepforward vanes. A vane inlet side sweepforward design form is adopted, a rim is thin, a hub is thick, and sundries which flow into a vane inlet move from the rim to the hub side under the rotation action of the vane on the hub side and flow into a flow channel along with the rotating vane, so that the sundries are prevented from winding and wearing the hub of the vane; therefore, the service life of the vane is prolonged and a motor is effectively protected.
Description
Technical field
The present invention relates to a kind of axial-flow pump, particularly a kind of axial-flow pump impeller of sweepforward blade.
Background technique
At present, known axial-flow pump impeller all adopts inlet side sweepback design, flows to the foreign material of impeller inlet, at first under the turning effort of hub side blade, and outwards circular motion, and along with the blade of rotation gets into runner.Though this kind structural type has certain anti-blockage capability, use the blowdown pumping plant, water quality is complicated, and silt is many; Foreign material are many, still cause the impeller blade wheel rim to twine foreign material easily, wear and tear even break; Cause outer end mechanical seal distortion, cause mechanical seal to be lost efficacy, the motor water inlet; Pump is frequently reported to the police, and increases maintenance frequency, even burns out motor.
Summary of the invention
For addressing the above problem, the present invention adopts entrance edge of blade sweepforward design form, and the wheel rim place is thin; Wheel hub is thick, flows to the foreign material of impeller inlet, at first under the turning effort of wheel rim lateral lobe sheet; The place moves to hub side by wheel rim, and along with the blade of rotation gets into runner, thereby avoided winding and the wearing and tearing of foreign material at blade rim; Improve the working life of impeller, effectively protected motor.
Realize that above-mentioned purpose adopted technological scheme be:
So-called sweepforward blade that is to say that inlet edge of impeller blade protracts, against coming flow path direction; Wheel rim is preceding, wheel hub after, entrance edge of blade is arranged in center line the place ahead of inlet side and wheel hub intersection point fully; Foreign material are the hub side of wheel rim effluent after leaning on from protracting earlier, thereby make foreign material get into runner smoothly, avoided winding and the wearing and tearing of foreign material at blade rim; Improve the working life of impeller, effectively protected motor.The general number of blade Z of this kind impeller is not less than 2, and it is not enough to the restraining force of flow that the number of blade is crossed the major general, and the number of blade too much will influence the passing capacity of impeller again, so its number of blade should moderately be selected.
Advantage of the present invention is: avoided blade to be broken, strengthened the passing capacity of impeller.
The invention has the beneficial effects as follows: effectively avoided the winding of foreign material, improved impeller life in the wheel rim side.
The present invention is on probation through the user, reflect respond well, the working life that can improve impeller.

Fig. 2 is the planimetric map of same embodiment's axial-flow pump impeller.
Among Fig. 1: 1. entrance edge of blade, 2. exit edge of blade, 3. blade, 4. wheel hub, 5. import wheel rim side, 6. import hub side.
Among Fig. 2: 1. entrance edge of blade, 2. exit edge of blade, 3. blade, 4. wheel hub, 7. inlet side and wheel hub intersection point center line.
Embodiment
Fig. 1 and Fig. 2 have confirmed the structural type of sweepforward blade axial-flow pump impeller in the present embodiment jointly, mainly by entrance edge of blade (1), and exit edge of blade (2); Blade (3); Wheel hub (4), blade rim side (5), blade hub side (6) and inlet side and wheel hub intersection point center line (7) are formed.Impeller is high speed rotating under the drive of pump shaft; Flow to the foreign material of impeller inlet; At first under the turning effort of wheel rim side (5) blade (3), move to hub side (6) by wheel rim side (5), and along with the blade (3) of rotation gets into runner; Thereby winding and the wearing and tearing of foreign material have been avoided, the working life of having improved impeller at blade rim (5).Wherein, the inlet side of blade (1) is arranged in the place ahead (with respect to coming flow path direction) of inlet side (1) and wheel hub (4) intersection point center line (7) fully, and wheel rim side (5) is thin; Hub side (6) is thick; Thereby be beneficial to foreign material and get into impeller channel, realize its anti-winding performance, prolong impeller life.
Claims (3)
1. sweepforward blade axial-flow pump impeller, mainly by entrance edge of blade (1), exit edge of blade (2), blade (3), wheel hub (4), blade rim side (5), blade hub side (6) and inlet side and wheel hub intersection point center line (7) are formed.It is characterized in that: the inlet side of blade (1) is arranged in the place ahead of inlet side (1) and wheel hub (4) intersection point center line (7) fully.
2. sweepforward blade axial-flow pump impeller according to claim 1 is characterized in that: blade rim side (5) is thin, and hub side (6) is thick, and foreign material are moved to hub side (6) by wheel rim side (5).
3. sweepforward blade axial-flow pump impeller according to claim 2, it is characterized in that: impeller blade is counted Z and is not less than 2.
