38、ISO 2009 All rights reserved/Tous droits rservs vii Introduction Rotary shaft lip-type seals are used to retain fluid in equipment where the differential pressure is relatively low. Typically, the shaft rotates, and the housing is stationary, although in some applications the shaft is stationary, an
39、d the housing rotates. Dynamic sealing is normally the result of a designed interference fit between the shaft and a flexible element incorporated in the seal. Similarly, a designed interference fit between the outside diameter of the seal and the diameter of the housing bore retains the seal and pr
40、events static leakage. Careful storage, handling and proper installation of all seals are necessary to avoid hazards, both prior to and during installation, that can adversely affect service life.

Une tanchit dynamique est normalement le rsultat dun ajustement serr volontaire entre larbre et un lment dtanchit souple incorpor la bague dtanchit. De faon similaire, un ajustement
43、serr volontaire entre le diamtre extrieur de la bague dtanchit et le diamtre dalsage du logement retient la bague dtanchit et empche les fuites statiques.

46、ppropriate vocabulary for seals utilizing elastomeric sealing elements where the terms and definitions given in ISO 5598 apply.

48、seals incorporating thermoplastic sealing elements.
