Description
Technical field
The invention belongs to field of fluid machinery, the nothing for being related to a kind of attached wall unitary rotation of screw type impeller and non-stop layer axis is blocked up
Plug pump, suitable for the conveying of each fluid, semifluid and solidliquid mixture.
Background technology
Non-blinding pump is the more special and critically important pump of field of fluid machinery one kind, for conveying various dense paddle objects, consolidating
Liquid mixture, powdered rubber etc., application range is extremely wide, is in great demand.According to its operation principle, Non-blinding pump generally can be with
It is divided into vacuum pump, jet pump, centrifugal non-stick pump several species, respectively there are advantage and disadvantage.The suction of its intermediate pump, jet pump
Working barrel does not have impeller or blade, has preferable blocking-free performance energy, and material is higher without loss rate, but efficiency is relatively low or aspirates
Work is discontinuous, and lift is limited, and application is subject to certain restrictions.
Centrifugal non-stick pump with impeller in contrast, working efficiency is higher, suction operation is continuous, can design compared with
High lift, thus application is relatively broad, Turo pump, Double Channel Pump, helico-centrifugal pump several species is generally included, with difference
Runner and Impeller Design, and with higher material by performance and blocking-free performance energy, application is relatively broad.It is aforementioned various types of
The centrifugal non-stick pump of type without exception, is respectively provided with the impeller that a central shaft drives rotation, is designed by impeller shape
Optimization or mounting means optimization reach certain without blocking effect.These centrifugal non-stick pumps with central shaft impeller without
By what kind of design and optimization carried out, the impeller of central axis always generates the material of conveying certain destruction during work
And influence, to be not suitable for because there is always relative motions, material situation between the impeller and fixed pump housing wall of its rotation
When, when for example the ratio of material and medium fluid is improper, it is likely that winding and blocking accident occurs, that is to say, that its material is defeated
Sending no loss rate aspect, there are certain natural defects, are the shortcomings that its are main.
The machineries such as screw pump, the Shaftless screw conveyor of other type, it may have good blocking-free performance energy, but this
The usually not good suction of class machinery and lift, being chiefly used in occasions, the length of the pump housing such as material charging conveying is generally exactly
The distance that material can convey, and there is also opposite fortune between the impeller of such pump movement and fixed pump housing wall
It is dynamic.
Invention content
Present invention seek to address that has the Non-blinding pump of type, it is difficult to take into account working efficiency, suction and lift and without stifled
The drawbacks of plug handling capacity, material can be required without loss rate universality, innovatively devises a kind of screw type impeller and is attached to
Integrally rotated novel Non-blinding pump on wall is pumped, there is non-stop layer axial screw type impeller, screw type impeller is mounted on pump
On body wall and as pump housing wall rotates together, so as in the transmission process of fluid, be not present in the main pump that fluid passes through
The component of any relative motion, thus with excellent material without loss rate and good blocking-free performance energy.Based on above-mentioned unique
Design, the novel Non-blinding pump that the present invention designs have the advantages of centrifugal non-stick pump, and improve its shortcoming, have higher
Suction and lift, and with better blocking-free performance energy, lower material has broad application prospects without loss rate.It can be with
Preferably it is suitable for the pumping conveying of the fluids such as dense paddle material, solid-liquid mixture, there is better blocking-free performance energy and work
Efficiency.
The technical scheme is that:
A kind of Non-blinding pump of attached wall rotation screw type impeller, the pump main body of the pump is rotary structure, even number
Symmetrically attached wall is fixedly mounted on the inner wall of pump main body screw type impeller, and the arrival end of each screw type impeller from pump main body prolongs
Reach the port of export of pump main body;Pump main body both ends are connected to by spring bearing on pump housing shell respectively, wherein pump main body both ends
The outer shroud of spring bearing forms the installation support section of pump by fixedly connected part and pump housing cage connection;Pump main body both ends with
The inner ring connection of spring bearing, pump main body body wall outside are moved by fixedly connected part B connection drive gears or belt pulley, access
The power in power source so as to make the attached wall screw type impeller of pump main body and its inside unitary rotation together, forms the excessively stream part of pump,
The wherein component without relative motion;
The distance of the screw type impeller narrowest position of the attached wall installation, it is transversal more than the material for aspirating conveying solid content
1.25 times of face maximum gauge.
In order to improve the working efficiency of the invention pumped and suction and lift, the screw type impeller warp of the attached wall rotation of this pump
Special optimization is crossed to calculate and design, and reach following effect:The low-pressure area of its interior flow field is formed in the front half section of pump, with profit
In the suction of material, the suction of pump is improved;Screw type turbomachine can be converted to by institute by the unitary rotation of screw type impeller
The mechanical energy of aspiration fluid and material forms the higher-pressure region of its interior flow field in the second half section of pump, so as to improve the lift of pump.For
Preferably reach foregoing advantages, pump the arrival end of main body, the port of export is located on same axis, and the bore of the port of export be less than into
The bore at mouth end, pump discharge end passes through fixedly connected part A connection spring bearing inner ring.In pump housing shape and working method, this
Invention, which pumps, is somewhat similarly to axial-flow pump, but the central shaft and rotary blade of the invention pumped there is no axial-flow pump, but pump housing wall
The impeller of upper attachment is rotated with the pump housing, thus in the pump body of present invention pump transportation work medium, phase is not present
To the component of movement, therefore has excellent blocking-free performance energy, and have better working efficiency.
Present invention pump is due to special screw type Impeller Design, and the excessively stream part direction of rotation is fixed, by screw type
Impeller moves towards to determine, during work can only forward rotation working media could be aspirated and be conveyed, it is impossible to reversely rotation
Turn.
The quantity of present invention pump screw type impeller is even number, and minimum number is 2.And it is distributed symmetrically to be installed on pump
On body wall, so as to make pump rotation work more steady in the process.
In conclusion a kind of Non-blinding pump of attached wall rotation screw type impeller proposed by the present invention, in the course of work not
Change the flow direction of working media, force the flow direction of working media by axially translated for diameter unlike other centrifugal non-stick pumps
To so as to not lose more conversioning mechanical energies, with higher working efficiency.The screw type impeller optimized by special designing
It being fixedly mounted on pump housing wall, is rotated with pump housing wall, pump body does not have the component of relative motion, thus with better
Blocking-free performance energy.The present invention pumps had aforementioned advantages and feature, it is made to have better than existing various types of Non-blinding pumps
Better blocking-free performance energy, working efficiency and suction, lift, suitable for various fluids, semifluid, solidliquid mixture, powder object
The suction and conveying of matter, have broad application prospects.
