30-03-2006This axial shifting could significantly alter the flow pattern and the flow-induced rotordynamic forces in labyrinth seals, which in turn, can considerably affect the rotor-seal system performance. This paper investigates the influence of the rotor axial shifting on leakage rate as well as rotordynamic forces in high-low labyrinth seals over a range of

Floating labyrinth seals were developed for use in RENK slide bearings. They are twou0001 piece seals, freely movable in a seal carrier or directly in the bearing housing. Both halves are held together by a garter spring. The radial clearance between the seal and the seal carrier is approx. 1 mm. This prevents damage to the seal by the shaft

10-10-2020As the name suggests, a labyrinth seal creates a complex flow passage to increase pressure loss across it and reduces leakage flow rate for a given clearance. Being the most widely used in gas turbines, these seals are inexpensive, noncontacting, and they operate under a wide range of pressures, temperatures, and rotor speeds.
