Description

Sentrifugalpumpe. Centrifugal pump.

Foreliggende oppfinnelse angår sen-trifugalpumper og særlig, men ikke bare pumper som er beregnet på pumping av væsker som inneholder partikler. The present invention relates to centrifugal pumps and particularly, but not only, pumps which are intended for pumping liquids containing particles.

Partiklene kan være fibermaterialer, mineraler, malm, sand, støv og lignende, og en spesiell men ikke den eneste an-vendelse av oppfinnelsen, er sentrifugal-pumper som sitter i vannfiltreringskretsen i enkelte typer husholdningsvaskemaskiner. The particles can be fiber materials, minerals, ore, sand, dust and the like, and a particular but not the only application of the invention is centrifugal pumps which sit in the water filtration circuit in certain types of household washing machines.

I vaskemaskiner av denne art benyttes en sentrifugalpumpe til å trekke vann fra vaskebeholderen og til å føre vannet til-bake til beholderen gjennom et finmasket filter som samler partiklene av lo, hår og smuss som er suspendert i vannet. Et pro-blem man støter på ved befordring av par-tikkelførende væsker er å hindre avsetning av partiklene mellom de av pumpens flater som beveger seg i forhold til hverandre. Virkningen av disse avsetninger hvis man ikke prøver å kontrollere dem, vil være at pumpen stoppes til og de roterende deler i pumpen kjører seg fast. In washing machines of this type, a centrifugal pump is used to draw water from the washing container and to return the water to the container through a fine-mesh filter that collects the particles of fluff, hair and dirt that are suspended in the water. A problem encountered when transporting particle-carrying liquids is to prevent the deposition of the particles between those of the pump's surfaces which move in relation to each other. The effect of these deposits, if no attempt is made to control them, will be that the pump stops and the rotating parts in the pump jam.

En hensikt med foreliggende oppfinnelse er å redusere avsetningen av disse partikler mellom flater som i sentrifugal-pumper beveger seg i forhold til hverandre. One purpose of the present invention is to reduce the deposition of these particles between surfaces which in centrifugal pumps move relative to each other.

Anordningen hvor oppfinnelsen benyttes omfatter en sentrifugalpumpe med et pumpekammer, en rotor anbragt i kammeret og montert på en dreibar aksel som strekker seg aksialt gjennom dette og tett i forhold til kammeret, en innadrettet del av veggen i kammeret, hvilken rotor har en hette som i det vesentlige omslutter den innadrettede del av veggen i kammeret og inneholder en luftpute mellom undersiden av hetten og de tilstøtende flater av den nevnte del når pumpen står plasert med hetten over delen og når væske kommer inn i kammeret, hvilken luftpute hindrer væske fra å komme til flatene mellom den nevnte del og de deler som er dreibare i forhold til denne. The device in which the invention is used comprises a centrifugal pump with a pump chamber, a rotor placed in the chamber and mounted on a rotatable shaft which extends axially through this and close to the chamber, an inwardly directed part of the wall of the chamber, which rotor has a cap which in substantially encloses the inwardly directed portion of the wall of the chamber and contains an air cushion between the underside of the cap and the adjacent surfaces of said portion when the pump is positioned with the cap over the portion and when liquid enters the chamber, which air cushion prevents liquid from reaching the surfaces between the said part and the parts which are rotatable in relation to it.

Den innadrettede del av veggen i kammeret er fortrinsvis et fortykket parti av huset som danner kammerets bunn og akselen strekker seg gjennom en sentral boring i denne del. The inwardly directed part of the wall in the chamber is preferably a thickened part of the housing which forms the bottom of the chamber and the shaft extends through a central bore in this part.

For at oppfinnelsen lettere skal kunne In order for the invention to be able to more easily

forstås skal det vises til tegningen der: Fig. 1 viser en utførelsesform for en sentrifugalpumpe i henhold til oppfinnelsen med en del av det ytre hus fjernet og understood, reference should be made to the drawing where: Fig. 1 shows an embodiment of a centrifugal pump according to the invention with part of the outer housing removed and

fig. 2 viser pumpen sett fra siden og fig. 2 shows the pump seen from the side and

i snitt etter linjen A—A på fig. 1. in section along the line A—A in fig. 1.

På tegningen er pumpekammeret 1 i sentrifugalpumpen begrenset av et hus 2 som omfatter et ytre deksel 3 festet til en hoveddel 4 ved hjelp av et antall bolter 5 som strekker seg gjennom åpninger i hoveddelen 4 og er skrudd inn i gjengede hull i dekselet 3. Væske kommer inn i og forlater kammeret 1 gjennom et sentralt innløp 6 og et utløp 7 som begge ligger i dekslet. Hoveddelen 4 utgjør en del av veggen i huset og har et fortykket sentralt parti hvorav en del 8 stikker inn i kammeret 1. Alternativt kan delen 8 være en del som er festet til hoveddelen 4. For-tykkelsen på delen 4 har en boring 9 og en aksel 10 som strekker seg aksialt i denne boring og bæres av et par lagre 11 i boringen. Akselen er forsynt med en remskive 10' for drift av pumpen. In the drawing, the pump chamber 1 of the centrifugal pump is limited by a housing 2 comprising an outer cover 3 attached to a main part 4 by means of a number of bolts 5 which extend through openings in the main part 4 and are screwed into threaded holes in the cover 3. Liquid enters and leaves the chamber 1 through a central inlet 6 and an outlet 7 which are both located in the cover. The main part 4 forms part of the wall of the house and has a thickened central part of which a part 8 protrudes into the chamber 1. Alternatively, the part 8 can be a part that is attached to the main part 4. The thickness of the part 4 has a bore 9 and a shaft 10 which extends axially in this bore and is supported by a pair of bearings 11 in the bore. The shaft is fitted with a 10' pulley for operating the pump.

En rotor 12 som fortrinsvis er utført av plast, er anbrakt i kammeret og er forsynt med en hette 13. Dimensjonene på hetten er slik avpasset at når den sitter på akselen, omsluttes delen 8. Hetten er fortrinsvis skålformet og er festet til enden av akselen 10 på en eller annen hensikts-messig måte. Et eller flere blader eller skovler kan sitte på hettens konvekse flate. A rotor 12, which is preferably made of plastic, is placed in the chamber and is provided with a cap 13. The dimensions of the cap are adapted so that when it sits on the shaft, it encloses the part 8. The cap is preferably bowl-shaped and is attached to the end of the shaft 10 in some appropriate way. One or more blades or vanes may sit on the convex surface of the hood.

Det er viktig for tilfredsstillende drift av pumpen at den installeres i en slik stilling at rotoren roterer i det vesentlige om en vertikal akse med den innadrettede del 8 liggende under rotoren. Hvis hetten er skålformet vil de ytre kanter av hetten måtte ligge lavere enn oversiden av delen 8. Luft som til å begynne med finnes i pumpen blir da innesluttet i hetten når væskenivået stiger i kammeret og luften trykkes sammen slik at den danner en pute i hettens øvre del. Luftputen hindrer væske fra å trekke fram til lagrene i delen 8 og de tilstøtende flater mellom delen 8 og rotoren og/eller akselen der man har rela-tiv bevegelse mellom delene. Hvis væsken inneholder partikler i suspensjon kan partiklene ikke avsettes mellom disse flater. Gapet mellom undersiden av den ytre kant av hetten 13 og hoveddelen 4 er fortrinsvis omtrent 0,5 mm for å forhindre at store partikler væsken måtte inneholde kommer frem til hettens underside. It is important for satisfactory operation of the pump that it is installed in such a position that the rotor rotates essentially about a vertical axis with the inwardly directed part 8 lying below the rotor. If the cap is bowl-shaped, the outer edges of the cap will have to be lower than the upper side of part 8. Air that is initially present in the pump is then trapped in the cap when the liquid level rises in the chamber and the air is compressed so that it forms a cushion in the cap's upper part. The air cushion prevents liquid from reaching the bearings in part 8 and the adjacent surfaces between part 8 and the rotor and/or the shaft where there is relative movement between the parts. If the liquid contains particles in suspension, the particles cannot be deposited between these surfaces. The gap between the underside of the outer edge of the cap 13 and the main part 4 is preferably about 0.5 mm to prevent large particles the liquid may contain reaching the underside of the cap.

Det må sørges for at luft som er innesluttet under hetten ikke kan unnvike gjennom boringen 9 i hoveddelen 4 og for dette formål kan akselen 10 stikke gjennom en gasstett oljepakning 15 i en fordypning på oversiden av den innadrettede del 8. It must be ensured that air trapped under the cap cannot escape through the bore 9 in the main part 4 and for this purpose the shaft 10 can stick through a gas-tight oil seal 15 in a recess on the upper side of the inwardly directed part 8.
