The rotor pump comprises a pair of rotor double-shaft opposite rotating structures, rotors are arranged on the pair of rotor double-shaft opposite rotating structures, the rotors are provided with oblique wings which are spiral, and the oblique wings contacting with the two rotors are in positive spiral and negative spiral forms. The non-vibration rotor not only has the advantage of non-vibration function, but also has other applications. For example, by utilizing the non-vibration rotor, pumping property of the pump can be increased, more importantly, and flow of the pump can be increased by increasing rotating speed of the pump, thereby overcoming factors which limit flow increase due to vibration.
Description
Technical field
The utility model relates to the rotor pump technical field, specifically a kind of rotor pump and friction rotor thereof.
Background technique
Rotor pump is because compact structure, contains in pumping aspect the medium of viscosity, more and more used.But because there is uneven conveying principle in the rotor configuration of rotor pump, the marquis brings uncontrollable vibration problem to line transportation and equipment unit sometimes.Rotor pump is two pumps, according to positive discharge capacity principle work.Assembling two or a plurality of rotor on two movements that change relatively, revolving turns around shifts a certain amount of volume of material from the suction side to the discharge end.Up to the present, the rotor pump of selling on the market, which is so-called to have the rotor number of correct uniqueness and the discharge capacity process that rotor profile is produced, be not real and angle of swing synchronous.This unsettled degree is exactly flow difference Δ V (Vmax-Vmin) and mean flowrate Vm ratio, and promptly the volume degree of fluctuation also is the degree of pump vibration.General Δ V/Vm approximative value can D/A (distance A of top end diameter D and axle) expression.Ratio relation as shown in Figure 1 for Δ V/Vm and D/A (distance A of top end diameter D and axle).If rotor is 8 fonts (both wings rotors), Δ V/Vm destabilizing factor is near 18%.This just means that the volume flowrate degree of fluctuation is ± 9%.
In the connecting pipeline engineering, these volume fluctuations will cause variation in pressure under pumping system, and this is because the incompressible performance of medium.For example the pumping sewage sludge will cause periodic acceleration and deceleration.Shown in Figure 2, be that example is described this phenomenon with the three wings rotor.The result of this acceleration can calculate from volume property period of waves process, and brings maximum dynamic pressure, and these effects are realized that by the incompressible fluid cylinder two ends of pump constantly quicken and these materials that slow down simultaneously.Upper half part diagrammatic representation pumping volume of material situation of change.The increase of discharge volume of material ↑, the minimizing of discharge volume of material ↓.The stressed situation of change of lower half portion diagrammatic representation pumping material.Discharge material be accelerated ↑, discharge material be decelerated ↓.For rotor pump, discussing about causing vibration problem, even wrongheaded once and again technically method reduces vibration, Here it is increases the rotor number (use three wing pumps to replace two wing pumps since it is so, perhaps four wing pumps replaces three wing pumps, by that analogy).Theoretical research draws the phase counter-statement: if the rotor number is increased to 3 from 2, dynamic pressure will increase by 1.5 times (not stating) here.
There is a kind of method can solve vibration problem below.By observing Fig. 2, volume curve is along with the fluctuation situation appears in rotation angle, and people can draw by periodic fluctuation, a certain local the conveying too much, and a certain place is carried very few, causes vibration.
As shown in Figure 3, if there are two two wing rotor pumps to be arranged in parallel, pump rotor deflection 45 degree wherein produce the result of unstable degree so like this, be do not have that the deflection pump structure born results 1/20.Certainly people will be the construction expenditure of so perfect result's pump pay double.
The model utility content
The purpose of this utility model is for providing a kind of friction rotor that can subdue the vibration in the working procedure.
The technological scheme that realizes the foregoing invention purpose is as follows:
The friction rotor has the oblique wing, and the described oblique wing is shape in the shape of a spiral.
In the middle of the described friction rotor is metal-cored, the described metal-cored rubber that is coated with.
The described oblique wing is 2,3,4,6 or 8.
The described oblique wing is the helical rotation in 11 fens of 33 degree.
Another purpose of the present utility model is for providing a kind of rotor pump that adopts above-mentioned friction rotor.Its technological scheme is as follows:
Rotor pump comprises that a pair of rotor twin shaft to rotation structure, which is provided with rotor, and described rotor has the oblique wing, it is characterized by: the described oblique wing is shape in the shape of a spiral, and the contacted oblique wing of these two rotors is right-handed screw and backpitch.
In the middle of the described rotor is metal-cored, the described metal-cored rubber that is coated with.
The described oblique wing is 2,3,4,6 or 8.
The described oblique wing is the helical rotation in 11 fens of 33 degree.
Friction rotor of the present utility model is a kind of friction rotor, not only shows the friction functional advantage, also has other application.For example, adopt the friction rotor, the suction performance of pump will be enhanced, and the most important thing is, the flow of pump can increase by increasing revolution speed, has broken through flow limits raising because of vibration factor.
