The utility model aims at providing an improvement type symmetry formula double entry pump impeller, the atress of blade both sides is uneven when reducing impeller operation, improves blade life, increase fluid flow speed and imbibition ability improve the quick -witted efficiency of pump, improve pump machine lift.
Description
Technical field
The utility model is related to pump class, more particularly, to a kind of modified form symmetrical expression double-suction pump impeller.
Background technology
Pump leaf can be applicable to every field pumping unit, is commonly employed in industrial or agricultural.Such as steel industry, filling of supplying water
Irrigate system, petroleum industry, electricity generation system, chemical industry etc., all employ pumping unit, the structure of pump leaf and system in a large number
Make performance and directly affect whole system.
Existing pump machine adopts one group of blade, during the operating of pump machine, the blade axially unilateral extruding force by water, and stress is uneven
Weighing apparatus, blade easily consumes, and also easily causes the abrasion of impeller axle, reduces the service life of pump machine；And one side imbibition is less efficient.
Utility model content
The purpose of this utility model is for problem above, provides a kind of modified form symmetrical expression double-suction pump impeller, reduces leaf
During wheel operating, the force unbalance of blade both sides, improves blade service life, improves pump machine lift simultaneously, improves the effect of pump machine
Rate.
For realizing object above, the technical solution adopted in the utility model is: a kind of modified form symmetrical expression double-suction pump impeller,
Including the left wheel hub (1) being oppositely arranged, on the left flabellum (12) and right wheel hub (2) of the upper setting of right wheel hub (2), and left wheel hub (1)
The right wing leaf (21) of setting is also arranged opposite；It is evenly arranged between the described left wheel hub (1) being oppositely arranged and right wheel hub (2)
Deflector (4)；Described deflector (4) left and right two ends are connected with left flabellum (11), right wing leaf (21) respectively, and it is recessed to form flared type
Shape guiding gutter (3).
Further, described deflector (4) is equal with the number of left flabellum (11), right wing leaf (21).
Further, the number of described deflector (4) is no less than 4 pieces.
Further, the side being oppositely arranged of described left wheel hub (1) and right wheel hub (2) forms runner, and runner mouth sets
Put mutation formula annular boss (5).
The beneficial effects of the utility model:
1. when reducing impeller operation, the force unbalance of blade both sides, improves blade service life；
2. flabellum junction setting guiding gutter (3), increases fluid-flow rate and imbibition ability, improves the efficiency of pump machine；
3. runner mouth is provided with boss (5), reduces bore, increases internal pressure, improves pump machine lift.

Fig. 4 cuts open schematic diagram for the utility model scheme 2 right side.
Described in figure, mark is expressed as: 1, left wheel hub；2nd, right wheel hub；3rd, guiding gutter；4th, deflector；5th, boss；11st, left fan
Leaf；21st, right wing leaf.
Specific embodiment
In order that those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with the accompanying drawings to this reality
It is described in detail with new, the description of this part is only exemplary and explanatory, should not be to protection domain of the present utility model
There is any restriction effect.
As Figure 1-Figure 4, concrete structure of the present utility model is: the left wheel hub 1 that inclusion is oppositely arranged, right wheel hub 2, and
The left flabellum 12 of setting on left wheel hub 1 is also arranged opposite with the right wing leaf 21 of setting on right wheel hub 2；The described left side being oppositely arranged
It is evenly arranged with deflector 4 between wheel hub 1 and right wheel hub 2；Described deflector 4 about two ends respectively with left flabellum 11, right wing leaf
21 connections, and form flared type spill guiding gutter 3；Increase fluid-flow rate, improve the efficiency of pump machine.
Preferably, described deflector 4 is equal with the number of left flabellum 11, right wing leaf 21.
Preferably, the number of described deflector 4 is no less than 4 pieces.
Preferably, the side being oppositely arranged of described left wheel hub 1 and right wheel hub 2 forms runner, and the setting mutation of runner mouth
Formula annular boss 5；Improve pump machine lift.
When specifically used, the two-way water suction in impeller both sides, effectively reduce the current axial direction out-of-balance force that impeller is subject to；Simultaneously
Flabellum junction arranges guiding gutter 3, increases fluid-flow rate and imbibition ability, improves the efficiency of pump machine；Conveying liquid is from leaf
During wheel runner output, due to the presence of boss 5, export bore and die-off, internal pressure increases, improve pump machine lift.
It should be noted that herein, term " inclusion ", "comprising" or its any other variant are intended to non-row
The comprising of his property, so that including a series of process of key elements, method, article or equipment not only include those key elements, and
And also include other key elements of being not expressly set out, or also include intrinsic for this process, method, article or equipment institute
Key element.
Specific case used herein is set forth to principle of the present utility model and embodiment, above example
Illustrate to be only intended to help understand method of the present utility model and its core concept.The above is only of the present utility model preferred
Embodiment is it is noted that due to the finiteness of literal expression, and objectively there is unlimited concrete structure, for this technology
For the those of ordinary skill in field, on the premise of without departing from the utility model principle, some improvement, retouching can also be made
Or change is it is also possible to be combined above-mentioned technical characteristic by rights；These improve retouching, change or combine, or not
The improved design by utility model and technical scheme directly apply to other occasions, are regarded as protection of the present utility model
Scope.
