Description

463 850 2 och löphjulet ren, varvid pumpen blir funktionssäkrare än tidigare utan.att kräva ett ständigt återkommande lösningsgörande av löphjulet för rengöring. Vidare kan det i löphjulet befintliga excentret utföras så, att det vid ett löphjul med en vinge fungerar som motvikt för den av Vingen orsakade obalansen. Härvid besparas man många komplicerade balanseringsåtgärder. 463 850 2 and the impeller clean, whereby the pump becomes more reliable than before without requiring a constantly recurring loosening of the impeller for cleaning. Furthermore, the eccentric present in the impeller can be designed so that in the case of an impeller with a wing it functions as a counterweight to the imbalance caused by the wing. This saves many complicated balancing measures.

Uppfinningen beskrivs i det följande mera i detalj med hänvisning till bifogade ritningar, där FIGUR l visar ett uppfinningsmässigt excenter mellan löphjulet och pumphuset.The invention is described in more detail below with reference to the accompanying drawings, in which FIGURE 1 shows an eccentric according to the invention between the impeller and the impeller housing.

FIGUR 2 visar snittet utmed linjen II i.fig. l.FIGURE 2 shows the section along the line II in fig. l.

FIGUR 3 visar en föredragen utföringsform av uppfinningen.FIGURE 3 shows a preferred embodiment of the invention.

I fig. 1 visas ett löphjul 1, som roterar med hjälp av axeln 2.Fig. 1 shows an impeller 1, which rotates by means of the shaft 2.

Löphjulet är så monterat med hjälp av axeln mot pumphuset 3, att en smal springa 7 bildas däremellan. Väsentligt i uppfinningen är det, att både pumphuset 3 och löphjulet 1 är försedda med i förhållande till löphjulets 2 axel excentriska utskott 5, 6.The impeller is so mounted by means of the shaft against the pump housing 3 that a narrow gap 7 is formed therebetween. It is essential in the invention that both the impeller housing 3 and the impeller 1 are provided with eccentric projections 5, 6 in relation to the axis of the impeller 2.

Under pumpens gång roterar naturligtvis endast löphjulet, varvid den mellan utskotten 5, 6 belägna springans 7 tvärsnittsyta i förhållande till axeln 2 turvis växer och minskar. Som störst är denna yta då excentren 5, 6 är belägna helt mot varandra ooh som minst då löphjulet har roterat från detta läge l80°, vilket visas i fig. 2. Springan öppnar sig alltså emellanåt, varvid fasta partiklar som hamnat där avlägsnas. Med hänvisningssiffran 4 har utmärkts pumphusets 3 tätningsutrymme, i vilket axeltät- ningen monteras.During the course of the pump, of course, only the impeller rotates, whereby the cross-sectional area of the gap 7 located between the projections 5, 6 in relation to the shaft 2 alternately grows and decreases. This surface is largest when the eccentrics 5, 6 are located completely against each other and at least when the impeller has rotated from this position 180 °, which is shown in Fig. 2. The gap thus opens from time to time, whereby solid particles which have ended up there are removed. The reference numeral 4 indicates the sealing space of the pump housing 3, in which the shaft seal is mounted.

I fig. 3 visas en föredragen utföringsform av uppfinningen, där löphjulets 1 båda sidor är försedda med ett excenterpar. Vattnet som skall pumpas kommer till löphjulet nedifrån i fig. 3 via den breda kanalen 8. Själva kanalen fortsätter självfallet över springan 9 koncentriskt i förhållande till löphjulets rotations- axel. 3 465 830 För en fackman på området är det klart, att uppfinningen inte begränsar sig till de ovan anförda utföringsexemplen, .utan den kan varieras inom ramen för det bifogade patentkravet.Fig. 3 shows a preferred embodiment of the invention, in which both sides of the impeller 1 are provided with an eccentric pair. The water to be pumped comes to the impeller from below in Fig. 3 via the wide channel 8. The channel itself of course continues over the gap 9 concentrically in relation to the axis of rotation of the impeller. It will be apparent to one skilled in the art that the invention is not limited to the embodiments set forth above, but may be varied within the scope of the appended claim.
