Abstract
Without shearing without demulsification disc pump, its architectural feature is that the disc impeller of the pump is made up of gusset, connecting pole, disc after gusset, back shroud of impeller, impeller before front shroud of impeller, impeller to a kind of chemical industry, and the forward and backward cover plate of impeller is fixed together by connecting pole；Disc is constituted and is evenly arranged on the medial surface of the forward and backward cover plate of impeller by preceding disc and rear disc；The axial height upper band of disc is tapered, and the radial width of disc gradually increases from import to outlet, forms inward turning flow structure.Produce boundary layer and sticky drawing force to smooth and promote fluid motion when disc rotates, medium is flowed to the outward flange of rotating disk, finally enter the discharge line of pump.So in the absence of the part for having mutual impact in the pump housing, medium will not produce pulsation, obstruction is inherently eliminated, the phenomenon that cavitation erosion, excessive wear, product medium are destroyed, mitigation weares and teares, improves performance；More reliable, more high rate is especially used in harsh occasion, also more economical, long service life safeguards few.
Description
First, technical field
The utility model is related to mechanical engineering pump class technical field, and specifically a kind of chemical industry is without shearing without demulsification disc
Pump.
2nd, background technology
Currently, the working method of all known pumps has a something in common, is exactly that the pump housing conveys thing by pressure
Material medium, medium only could be defeated by the contact with conveying machinery element (such as gear, plunger, barrier film, rotor, blade)
Send, mechanical part all produces serious impact to the pump housing and material.It is this impact for transfer of highly viscous medium, abrasive media,
Containing solid particle medium, the medium containing gas bubble, liquid, solid, the medium of gas mixing and shearing force is compared
It is breakneck for sensitive medium, it can produce pulsation, heavy wear is produced to pump, destruction is produced to pipeline.Also
Many working condition harshness application scenarios, such as：Medium contains solid particle, viscosity greatly, with very strong abrasion, corrosivity etc.
Occasion, using when there is strong destructiveness to pump, and cause pump performance degradation.
3rd, the content of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model to be to provide one kind and will not produce pulsation, mitigate mill
Damage, performance chemical industry high are without shearing without demulsification disc pump.
To achieve these goals, the technical solution adopted in the utility model is：The chemical industry is without shearing without demulsification disc pump
Mainly it is made up of the pump housing, disc impeller, pump cover, mechanical seal, bearing body, disc impeller is connected by rectangular thread with pump shaft
Connect；Described disc impeller is by gusset, connecting pole, disc structure after gusset, back shroud of impeller, impeller before front shroud of impeller, impeller
Into；Front shroud of impeller, back shroud of impeller are fixed together by connecting pole, and gusset is evenly arranged in the outer of front shroud of impeller before impeller
On side, gusset is evenly arranged on the lateral surface of back shroud of impeller after impeller；Described disc is by preceding disc and rear disc group
Into combining structure, forward and backward disc is evenly arranged on the medial surface of the forward and backward cover plate of impeller, and forward and backward disc correspondence arrangement combinations
In groups, certain combinations of gaps is formed between the two；The external diameter of forward and backward disc is the 80% of the forward and backward cover plate external diameter of impeller, preceding,
The internal diameter of disc is identical with the internal diameter at the forward and backward cover plate import of impeller afterwards, and the axial height upper band of disc is tapered, the footpath of disc
Gradually increase to outlet from import to width, form inward turning flow structure.
Described connecting pole is uniformly distributed for 4 circumferences, at the 2/3 of disc impeller diameter.
The beneficial effects of the utility model are：Because impeller employs disc combination structure, disc produces border when rotating
Layer and the smooth promotion fluid motion of sticky drawing force, make medium flow to the outward flange of rotating disk, finally enter the discharge line of pump.Institute
So that, in the absence of the part for having mutual impact, medium will not produce pulsation in the pump housing, obstruction, excessively cavitation erosion, mill are inherently eliminated
The destroyed phenomenon of damage, product medium, mitigates abrasion, improves performance；Especially using more reliable, higher in harsh occasion
Rate, also more economical, long service life safeguards few.Can be widely applied to pharmacy, bioengineering, chemical engineering sewage, grape wine, starch,
The industry such as papermaking and food, for convey have high viscosity, abrasion, containing solid particle, the medium containing gas bubble or
Person's liquid, solid, the medium of gas mixing and to shearing force than more sensitive medium.
4th, illustrate
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is for a kind of chemical industry of the utility model without shearing without demulsification disc pump sectional structure chart.
Fig. 2 is a kind of chemical industry of the utility model without structure chart of the shearing without demulsification disc pump dise piece impeller.
Fig. 3 is the B-B sectional views of Fig. 2.
In figure：1. the pump housing, 2. disc impeller, 3. pump cover, 4. mechanical seal, 5 bearing bodies, 6. gusset before impeller, 7. impeller
Front shroud, 8. back shroud of impeller, 9. gusset after impeller, 10. connecting pole, disc before 11., disc after 12..
5th, specific embodiment
In the accompanying drawings, a kind of chemical industry of the utility model is without shearing without demulsification disc pump, and the pump is main by the figure pump housing 1, disc
Impeller 2, pump cover 3, mechanical seal 4, bearing body 5 are constituted, and disc impeller 2 is connected by rectangular thread with pump shaft；Described disk
Piece impeller 2 is made up of gusset 9, connecting pole 10, disc after gusset 6, back shroud of impeller 8, impeller before front shroud of impeller 7, impeller；Leaf
Wheel front shroud 7, back shroud of impeller 8 are fixed together by connecting pole 10, and gusset 6 is evenly arranged in front shroud of impeller 7 before impeller
On lateral surface, gusset 9 is evenly arranged on the lateral surface of back shroud of impeller 8 after impeller；Described disc is by preceding disc 11 with after
Disc 12 is constituted, and forward and backward disc 11,12 corresponding parallel group synthesis groups, the present embodiment use 8 groups of parallel discs.Forward and backward disk
Piece 11,12 is evenly arranged on the medial surface of the forward and backward cover plate 7,8 of impeller, and the correspondence of forward and backward disc 11,12 arrangement combinations are in groups,
Certain combinations of gaps is formed between the two；The external diameter of forward and backward disc 11,12 be the forward and backward cover plate 7 of impeller, the 80% of 8 external diameters,
The internal diameter of forward and backward disc 11,12 is identical with the internal diameter at the forward and backward cover plate 7 of impeller, 8 imports, with cone on the axial height of disc
Degree, the radial width of disc gradually increases from import to outlet, forms inward turning flow structure.Described connecting pole 10 is 4 circumferences
It is uniformly distributed, at the 2/3 of the diameter of disc impeller 2.
When medium will be hierarchically attached on the surface of impeller rotating disk into the pump housing, when rotating disk is rotated, medium can be simultaneously
Row successively increase, until forming boundary layer.Rotational energy then from rotating disk successively to liquid transfer, thus on the whole width of rotating disk
Constitute speed and barometric gradient.Border ply stress, viscous stress and centrifugal force are combined together, and composition one is efficiently powerful to answer
The field of force, medium protectively " is drawn in " pump housing, medium is flowed to the outward flange of rotating disk by it by laminar flow, finally enters the row of pump
Go out pipeline.
