Abstract
The invention relates to a spiral axial-flow pump which mainly comprises a horn mouth (1), a spiral axial-flow impeller (2), space guide vanes (3), a shaft (4), mechanical seals (5), bearings (6), submersible motors (7) and the like. The spiral axial-flow pump is characterized in that a novel forward-swept vane design method is adopted by the spiral axial-flow pump, an impeller inlet edge (8) extends forwardly, the spiral axial-flow impeller (2) adopts a conical wheel hub, the highest position of the wheel hub is positioned at the root part of the impeller inlet edge (8), so that water flow forms a wheel hub low pressure area (10) at the highest position of the wheel hub, the acute angle part of an inlet guides sundries to the position nearby an axis due to the action of the absorbing force of the wheel hub low pressure area (10), then the sundries are pushed along the axis by utilizing the spiral action, and finally flow out from an impeller outlet edge (11). According to the spiral axial-flow pump, the characteristics of forced feed, no blockage, no winding and the like of the spiral axial-flow pump can be realized, the running condition of the pump in the small flow rate can be improved effectively, the shaft power of the pump can be controlled well, and the phenomenon of overload in the whole process can not occur.
Description
Technical field
The present invention relates to a kind of volute pump, particularly a kind of spiral axial-flow pump.
Background technique
Domestic sewage treatment at present mainly contains sewage pump, sludge pump, submersible axial flow pump, torque flow pump, helico-centrifugal pump etc. with pump.Take a broad view of applicable cases; Though having with pump, existing various sewage treatments pump the better performance that contains particle, impurity mixed solution; But owing to limit by pump type structure, pump can curl and plugging fault at work often, and material is destroyed serious; More can't be used to pump the material (like activated sludge) that long fibre, big particle diameter solid matter and requirement do not damage, far can not satisfy the needs of industries such as sewage treatment.Though helico-centrifugal pump possesses characteristics such as no obstruction, non-destructive, high-performance, is suitable for sewage treatment, and required big flow can not be provided.
Summary of the invention
For addressing the above problem; The invention provides a kind of spiral axial-flow pump; It is one type of new pump of be carrying the solidliquid mixture design, and its working principle is that pump shaft drives the rotation of screw type impeller, medium in the constraint lower edge of helical blade helix direction dish out; Through behind the water conservancy diversion of stator, flow out vertically.The spiral axial-flow pump adopts the spiral axial--flow blading to replace traditional axial-flow pump airfoil fan; Blade adopts the sweepforward designing method to become the helical blade of distortion; On the cone hub body, prolonged vertically by suction port, the radius of blade increases gradually, forms spiral flow channel.Under the constraint of big cornerite helical blade; Medium transmits energy gradually smoothly along blade, impels the pressure of blade surface medium and speed to be tending towards evenly, thereby has effectively avoided the winding of foreign material on the impeller inlet limit; Significantly improve the conveyance capacity of pump, enlarged the application area of pump.
Realize that above-mentioned purpose adopted technological scheme be:
The spiral axial-flow pump adopts novel sweepforward blade design method; Entrance edge of blade protracts; Impeller adopts cone hub, and the wheel hub highest point is positioned at the entrance edge of blade root, thereby makes current form a low pressure area herein; The acute angle portion of import utilizes screw action to make it to advance along axis near the axle center of under the effect of low pressure area suction foreign material being led again.Thereby realized the positive feed of spiral axial-flow pump, do not had obstruction, do not have characteristics such as winding, non-destructive, avoided pump in use to receive this difficult problem that limits of place and Environmental Conditions.And through the import and export diameter of control impeller, the blade exit width is imported and exported major parameters such as laying angle, better controlled the air horsepower of pump, do not have hump thereby make in the overall process of spiral axial flow pump operation, do not have the overload phenomenon.
The invention has the beneficial effects as follows: improved the mobility status in the pump, enlarged the application area of pump, effectively avoided the winding of impurity in impeller, overall process does not have the overload phenomenon and takes place.
The present invention is on probation through the user, and reaction effect is good.
