Abstract

Den foreliggende oppfinnelse angår en tetning for bruk til tetting av en roterende del av en tetning som er spesielt velegnet for å tette de stordiameterdeler av tromler som brukes i store vaske- og filtersylindere og akslinger i treforedlingsindustrien. Vedkommende vasker omfatter et stasjonært ytre skall (10), et matningskammer (12) for vaskevæske plassert inne i skallet, som er definert ved en perforert plate (16), og en roterende trommel plassert innenfor den nevnte over- flate (16) hvor trommelen har en væskegjennom- trengelig perforert overflate (18) hvorved det såkalte masserom (20) er definert mellom de nevnte perforerte overflater (16, 18), hvor vaskeren er utstyrt ved begge dens ender med en pakning for å tette den roterende trommel i forhold til det ytre skall, hvor terningen er utført ved en tetningsboks (26) og en tetningsdel plassert i den , og er et karakteristisk trekk ved den nevnte vasker at tetningsboksen (26) er utstyrt med en anordning (40) for å innføre et rrykkmedium, fortrinnsvis væske, inn i tetningsboksen (26).The present invention relates to a seal for use in sealing a rotating portion of a seal particularly suitable for sealing the large diameter portions of drums used in large washer and filter cylinders and shafts in the wood processing industry. The washes comprise a stationary outer shell (10), a wash liquid feeding chamber (12) located within the shell defined by a perforated plate (16), and a rotating drum located within said surface (16) wherein the drum has a liquid-permeable perforated surface (18) whereby the so-called mass space (20) is defined between said perforated surfaces (16, 18), wherein the washer is provided at both ends thereof with a seal to seal the rotating drum relative to the outer shell, wherein the cube is formed by a sealing box (26) and a sealing member located therein, and is a characteristic feature of said washer that the sealing box (26) is provided with a device (40) for introducing a tear medium, preferably liquid, into the sealing box (26).
