Abstract
The invention relates to a multifucntinal sand pump blade wheel and relative protective plate, which comprises a blade, an auxiliary blade, an inlet, a blade chamber and an axial hole. Wherein, the ring of auxiliary blade has a blade anti-immerge ring projection and a circular groove; the projective plate has relative ring projection and circular groove; the ring projections and the circular grooves of blade and its projective plate are covered to form several bent parts, therefore, the former right-angle space is changed into the space with multi bents to reduce the effect of sand pulp on the abrasion element, to confirm the operation of sand pump, prolong the service life and reduce the cost.
Description
Technical field the invention belongs to a kind of sand pump impeller and backplate thereof that can obviously reduce axial pressure.
Do not consider cooperating between the existing sand pump impeller of background technique and its backplate the axial etch of slurries in the pump case problem, perhaps consider unreasonablely, the backplate that is positioned at the impeller top is fixed on pump case, and the gap between impeller is a right angle type basically, although with the gap of impeller radial parallel in, have back blades intrinsic on the impeller slurries in the gap can be thrown away, alleviate axial pressure, but act on not obviously, sealing effect is all bad.Pressure in the pump case has rising slightly, and slurries will outside spillage phenomenon occur along the gap maceration in axial slit, accelerates component wear, befouling environment, and not only influence is produced, and also the rotating shaft and the accessory thereof of corrosion and damage sand pump cause device damage.
Summary of the invention the objective of the invention is to propose a kind ofly can to promote transfer ore pulp, the protection parts are not frayed, can obviously reduce the axial pressure to pump again, improve the sand pump impeller and the backplate thereof of sealing effect, to solve the problems of the prior art.
This multifunctional sand pump impeller and backplate thereof that the present invention proposes, it has blade, back blades, inlet, blade cavity and axis hole, it is characterized in that the impeller anti-leak ring ridge and annular groove are arranged in the accessory lobes loop, the corresponding ring ridge and annular groove are arranged on its backplate, the ring ridge and the mutual cover cap of annular groove on impeller and its backplate, gap between the two forms a plurality of bendings.
The correspondence ring ridge on impeller and the backplate and annular groove are one or multi-channel.
Annular groove shape of cross section corresponding on impeller and the backplate is rectangle or semicircle.
The impeller back blades is vertical bar shaped or spirality.
The present invention adopts the mode of the mutual cover cap of the ring ridge annular groove right angle type gap between sand pump impeller and its backplate to be become the gap of many bendings, under the drag effect of the centrifugal inertia force of impeller and generation between the two, reduced axial pressure, effectively reduce the influence of mortar pressure commute abrasive parts using in the pump case, prevented that slurries from leaking and corrosion from axial soaking, thereby guaranteed the normal operation of sand pump, prolonged service life of equipment, reduced user cost simultaneously.
Appended drawings 1 is plan view of the present invention (normal cross section when cooperating with its backplate).
Accompanying drawing 2 is impeller backplate plan view (A-A sections).
Accompanying drawing 3 is impeller backplate plan views.
Accompanying drawing 4 is impeller backplate worm's eye views.
Accompanying drawing 5 is impeller plan view (B-B sections).
Accompanying drawing 6 is impeller plan views.
Accompanying drawing 7 is impeller C-C sectional drawings.
Among the accompanying drawing 1-7, each component or label partly are as follows:
The 1-impeller leakproof ring ridge; 2-impeller leakproof annular groove; The 3-impeller eye; Chamber between the 4-blade; 5-impeller axis hole; The 6-backplate ring ridge; 7-backplate annular groove; 8-backplate body; 9-impeller back blades; The 10-impeller blade.
Embodiment transform example as with existing certain model sand pump impeller, its diameter is 133 millimeters, 5 helical blades (10) are arranged in the blade cavity (4), impeller eye (3) end face to the thickness of back blades (9) end face is 40 millimeters, impeller axis hole (5) is the orthohexagonal hole, and the nut of axle is installed in this hole.With the gap after backplate body (8) cooperates is a right angle type circumferential weld, press to press in the work when changing slightly, and slurries are easy to along this gap maceration to impeller shaft, and then maceration forms spillage outside pump case, causes parts damages such as wheel blade bearing, stop work and production.This example is suitably dwindled at the thickness with the accessory lobes loop, form in the volume within it that an impeller is anti-to soak the ring ridge (1) and corresponding impeller is prevented soaking annular groove (2), annular groove is wide 11 millimeters, dark 8 millimeters, on its backplate, form corresponding the backplate ring ridge (6) and backplate annular groove (7) simultaneously, keep certain interval.When impeller cooperates with backplate when being installed in the pump case, just original both gap has been changed over the shape that 5 bendings are arranged by right angle type, be equivalent to may maceration being provided with 5 road barriers to the slurries of impeller axial plane, impeller centrifugal inertia force radial effect in addition, effectively reduce axial pressure, avoided etch, the wearing and tearing of sand pump parts pump.So improved a collection of sand pump can reduce axial pressure 55-60% through on probation.The accident of not having axial spillage and abrasive parts using.
On this routine basis, when annular groove was increased to 2 roads and 3 roads, the antihypertensive effect in gap increased thereupon.Increase to some extent but the device fabrication cost is also corresponding.When preventing that soaking the annular groove shape of cross section changes semicircle into, effect quite changes quite, changes small.
Claims (4)
1, a kind of sand pump impeller of anti-axial etch, it has blade, back blades, inlet, blade cavity and axis hole, it is characterized in that having in the accessory lobes loop the anti-ring ridge and the annular groove of soaking of impeller, the corresponding ring ridge and annular groove are arranged on its backplate, the ring ridge and the mutual cover cap of annular groove on impeller and its backplate, gap between the two forms a plurality of bendings.
2, sand pump impeller according to claim 1 is characterized in that the correspondence ring ridge and the annular groove on impeller and the backplate is one or multi-channel.
3, sand pump impeller according to claim 1 is characterized in that annular groove shape of cross section corresponding on impeller and the backplate is rectangle or semicircle.
4,, it is characterized in that the impeller back blades is vertical bar shaped or spirality according to the described sand pump impeller of one of claim 1 to 3.
