Labyrinth seals
WebApr 23, 2024 · (1) We have optimized the basic parameters affecting the operation of the labyrinth seal. The values established are as follows: inclination of the crest’s lateral faces 2–10%, crest height 6%, channel length 5%, sharpness of crest 2.5% (or less), rounding at the base of the crest. Modeling permits 50% decrease in the losses through the gap.

WebLabyrinth seals and clearance seals: reduce friction maintain low operating temperatures experience little-to-no wear when maintained operate at high speeds have a long service life Labyrinth seals and clearance seals are often available in aluminum, bronze, steel, or plastic materials like PTFE. WebThese seals have performed equally well in such industrial applications as gun drills, gearboxes and pump housings. They use a single Al-Ni-Co magnet annulus to attract the opposing seal face. A rather similar seal, incorporating a series of strong rare-earth magnet rods that attract the opposing face.

[ ′lab·ə‚rinth ‚sēl] (engineering) A minimum-leakage seal that offers resistance to fluid flow while providing radial or axial clearance; a labyrinth of circumferential knives … WebOur comparison assumes a cost of $10 for two lip seals (with 4 changes per year) vs. $300 for two rotating labyrinth seals (with one change every 4 years); in each case, the cost of maintenance labor would be $500 per event. Lip seal replacements would cost ($10+$500)*4 =$2,040 per year, or $8,160 over 4 years.
WebDec 17, 2011 · The second sealing technology, the labyrinth seal, is usually comprised of a machined rotor and stator retained with a bolt-on flange or O-ring compression. The typical labyrinth seal is designed for non-contact, virtually eliminating wear on the internal components of the seal. Through the use of torturous paths and drain ports, external ... WebJul 7, 2024 · Labyrinth seals are used for many low-pressure air compressors, especially when robustness is more important than low leakage. They are normally made of metal, mainly aluminum, but thermoplastics can be used for higher corrosion resistance or better rubbing behavior. Do labyrinth seals leak?
