Hace 4 días · In order to investigate the impact of honeycomb on the leakage of the multiple seals system with the aid of the CFX analysis system, this paper attempts to import a more realistic flow field model with multiple labyrinth seals extracted from the support seal system in the low-pressure turbine part of a turbofan engine model , exemplified in Fig. 1.
25 de jun. de 2024 · In the present work, an environment for the shape opti-mization of a labyrinth seal is described. A program for a parameterized, automated grid generation is coupled with a commercial Computational Fluid Dynamics (CFD) flow solver and an optimization algorithm.
19 de jun. de 2024 · The maximum flow-induced stresses on the pump–turbine runner at the full load were below 2 MPa ... tube passage, crown chamber, band chamber, upper labyrinth seal, and lower labyrinth. seal and ...
18 de jun. de 2024 · One critical component that ensures both the longevity and performance of such systems is the TK labyrinth seal. This seal, designed with a complex array of grooves and ridges, is integral in preventing fluid leakage, contaminant ingress, and maintaining optimal operating conditions.
Hace 3 días · A floating ring seal is a non-contact fluid seal installed on a rotor, which separates two chambers with a high-pressure drop by a high-pressure fluid film formed by high-speed rotation of the rotor and eccentric operation of the floating ring [1,2].Its excellent reliability and high sealing efficiency are of great significance for the safe operation of rotating machinery.
24 de jun. de 2024 · Labyrinth seals are critical components in turbomachinery. They prevent leakage and maintain efficiency. In this blog post, we’ll explore what labyrinth seals are, how they work, and their importance in various applications.
21 de jun. de 2024 · Labyrinth Seal: Relies on a tortuous path to restrict fluid flow through a series of grooves or chambers. Mechanical Seal: Relies on physical contact between two flat seal faces, one rotating and one stationary, to prevent leakage.
