Abstract
Description
Die
Erfindung bezieht sich auf eine selbstansaugende Flügelradpumpe
(Impellerpumpe) mit doppelter Wirkungsweise (Bi- oder Dual-System)
für empfindliche
(geringe Elastizität)
Elastomere-Impellerlaufräder. Der
Pumpenzylinder
Das
System dieser Flügelradpumpen
ist bekannt- allerdings nur in der einfachen Ausführung (Wirkungsweise)
(
Der
Erfindung liegt daher die Aufgabe zugrunde:
Eine zuverlässliche
Pumpe auch für
empfindliche Elastomere ohne Leistungseinbußen zu schaffen, indem das
Spannungspotential und proportional dazu das Fördervolumen um ca. die Hälfte reduziert,
aber durch das zweifache System (Dual-System) (
To provide a reliable pump even for sensitive elastomers without sacrificing performance by reducing the voltage potential and proportional to the delivery volume by about half, but by the dual system (dual-system) (
Die Erfindung löst die Aufgabe dadurch, nicht nur die mechanische Zerstörung und die Flügel-Randspannungen, die sogar hochelastische Flügel zerstören, zu eleminieren, wie in der Patentanmeldung A160/2003, DPMA 103 11 655.9, beschrieben und geltend gemacht, sondern auch die Haupt-Biegespannungen der Flügel soweit zu reduzieren, sodass sie innerhalb der Elastizitätsgrenze operieren können, durch:
- a.) eine 40-60%ige Verkürzung des
Federweges f (Durchbiegung) (
9 ) der Flügel - b.) die Optimierung (Ausbildung) der parallelen Flügelstärke "s" nach Form gleicher Festigkeit" um einen annähernd gleichen Anpressdruck P an die Gleitfläche wie im Einfachsystem, durch konstante Biegespannung σ = M/W [N/cm2] entlang der Flügellänge I, zu erhalten – (d.h. das Flächenträgheitsmoment [cm4] wächst proportional zum Biegemoment M[Ncm]
- c.) Erhöhung
der Flügelanzahl
25 am Flügelrad
24 (7 ) als notwendige Maßnahme wegen der kürzeren Abstände zwischen Saug- und Druckzonen (Krümmungslinie c) und gleichzeitig den Belastungsanteil pro Flügel zu vermindern. - d.) durch die geometrische Formgebung des Pumpenhohlraum-Querschnittes in 4 spiegelbildliche Teil-Querschnittsflächen A, B, C, D, davon die 2 symmetrischen Querschnittsflächen (durch die y-Achse) D, A und B, C als Arbeitsquerschnitt für je ein Pumpensystem dienen.
- a.) a 40-60% shortening of the spring travel f (deflection) (
9 ) the wing - b.) the optimization (training) of the parallel wing thickness " s" according to the same strength "by an approximately same contact pressure P to the sliding surface as in the single system, by constant bending stress σ = M / W [N / cm 2 ] along the blade length I , - - (ie the moment of area [cm 4 ] increases in proportion to the bending moment M [Ncm]
- c.) Increase the number of blades 25 on the impeller
24 (7 ) as a necessary measure because of the shorter distances between suction and pressure zones (curvature c) and at the same time to reduce the load share per wing. - d.) by the geometric shape of the pump cavity cross-section in 4 mirror-image partial cross-sectional areas A, B, C, D, of which the 2 symmetrical cross-sectional areas (through the y-axis) D, A and B, C as working cross-section for each pump system serve.
Die
im Pumpenzylinder
Ein weiterer Vorteil dieses Doppel-Systems ist die biegespannungsfreie Antriebs- bzw. Motorwelle, weil keine Radialkräfte auftreten.One Another advantage of this double system is the non-bending stress Drive or motor shaft, because no radial forces occur.
In der Zeichnung ist die Erfindung anhand konstruktiver Ausführungsbeispiele dargestellt. Es zeigen:In the drawing is the invention with reference to constructive embodiments shown. Show it:
- a.) den Normalfall: gemeinsam (beide Systeme) ansaugen – gemeinsam weiterleiten (fördern)
- b.) die Mischung: getrennt ansaugen verschiedener (oder auch gleicher) Flüssigkeiten gemischt weiterleiten.
- c.) die Trennung: gemeinsam ansaugen – getrennt weiterleiten.
- d.) die freie Variante: getrennt (lokalmäßig) ansaugen – getrennt weiterleiten – oder umgekehrt.
- a.) the normal case: collectively (both systems) suck in - forward together (promote)
- b.) the mixture: separately forward separately sucked different (or the same) liquids.
- c.) the separation: suck in together - forward separately.
- d.) the free version: separate (local) suction - forward separately - or vice versa.
