Description
Pate nt-A ν SPRUC η :Pate nt-A ν SPRUC η:
Spaltdichtung für Kreiselpumpen, dadurch gekennzeichnet, daß an einer oder beiden Seiten des Kreiselrades (r) eine Ringfläche angeordnet ist, welche von innen nach außen durchlaufende Nuten (n) enthält und gegen eine andere, gleiche, glatte Ringfläche des Gehäuses gerichtet ist, so daß zwischen beiden ein enger Spalt (s) frei bleibt, und im Betrieb das durch den Spalt eindringende Wasser durch die Nuten (n) wieder nach außen befördert wird.Gap seal for centrifugal pumps, characterized in that an annular surface is arranged on one or both sides of the impeller (r) which contains grooves (s) extending from the inside to the outside and is directed against another, identical, smooth annular surface of the housing, so that a narrow gap (s) remains free between the two, and during operation the water penetrating through the gap is conveyed to the outside again through the groove (s).
Hierzu 1 Blatt Zeichnungen.1 sheet of drawings.
