Abstract

Roterende spyleverktøy innbefattende en rotor (1) med aksialt motstående trykkbalanserte mekaniske flatetetninger (15, 16, 17). Ventilerte øvre mekaniske flatetetninger (16, 17) gjør det mulig for rotoren (1) å bli drevet med det forholdsvis lave startmoment som er oppnåelig ved bruk av reaksjonskrefter fra forskutte fluidstråler (14) drevet av et trykksatt fluid. Når rotoren (1) blir forskjøvet aksialt på grunn av nedsettelsestilstander, utøver et trykkammer (12) en trykkubalanse på rotoren (1), som tvinger rotoren (1) til å gå tilbake til en normal driftsposisjon. Alternativ konstruksjon for å oppnå lavt startmoment innbefatter et volum plassert nær ved en nedre mekanisk flatetetning (15), volumet er koplet i fluidkommunikasjon med det trykksatte fluid. Mekaniske flatetetningsflater (15, 16, 17) blir fremstilt av ultraharde materialer, slik som wolframkarbid, silisiumkarbid og diamant. En justeringsring konstruert for å sikre at fluidstrålene (14) fjerner alt materiale fra målet til det beskyttende hus (3) før verktøyet kan fremskride kan inkluderes.
