Labyrinth seal design manual

A Theoretical Model for the Design of a Labyrinth Seal Gland 46 www.doorway.ru required number of cavities to get a minimum allowable leakage rate. II. oANALYSIS The geometrical configuration of the labyrinth seal selected and the coordinate system used in the analysis are shown in Fig. 1.

(August ) Orcun Inam, www.doorway.ru, Gazi University, Turkey Chair of Advisory Committee: Dr. Gerald L. Morrison Annular seals are devices used in turbomachinery to avoid flow losses which reduce efficiency. The dynamic stability of the machine is also improved by the seal. Seal Design Options Oil Seal Ingersoll Rand offers a complete range of seal where labyrinth seals cannot provide enough leakage protection • Seal system is completely oil-free Manual or customer-specified systems can be engineered for most gas seal types.

Under design operation labyrinth seals are essentially a controlled clearance seal without rubbing contact. As there is no surface to surface contact, very high relative speeds are possible and the geometry can be arranged to limit the leakage to tolerable levels. The rotating labyrinth ring carries a V-ring seal that seals against the stationary labyrinth ring. The V-ring seal blocks contaminants from entering the bearing housing and aids the purging of contamination and old grease when the seal is re-greased. Multi-stage axial labyrinth cartridge seal – includes two labyrinth rings, an internal low. The inner labyrinth seal actually consists of two separate sets of labyrinth teeth. The inboard set of teeth forms the seal balance labyrinth, which is subject to the high differential pressure explained previously. The outboard set of labyrinth teeth forms the seal gas labyrinth, which is between the process gas and the sealing gas.
