Labyrinth seals on rotating shafts provide non-contact sealing action by controlling the passage of fluid through a variety of chambers by centrifugal motion, as well as by the formation of controlled fluid vortices. ... This acts to prevent its escape, and also acts to repel any other fluid.
What is the advantage of using a labyrinth seal?
A labyrinth seal is a type of mechanical seal that provides a tortuous path to help prevent leakage. An example of such a seal is sometimes found within an axle's bearing to help prevent the leakage of the oil lubricating the bearing.
What is labyrinth packing?
one of the most widely used types of packing; a contactless device placed between two or more parts that move relative to one another. It consists of a row of narrow slits (or gaps) alternating with expansion chambers.
How are labyrinth seals made?
What is a Labyrinth Seal? A non-contact labyrinth seal is a type of mechanical seal designed by layering together metal sealing plates that combine to form a bunch of angles in a “maze-like” pattern. This complex maze-like pattern prevents contaminants and splashing liquids from hitting the bearing.
Where is labyrinth seal used?
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.
What is the function of labyrinth seal in turbocharger?
The bearings are separated from the blower and turbine by labyrinth seals. These seals are sealed by air supply from the discharge of blower to prevent oil entering the blower and to prevent contamination of the oil by the exhaust gas.Nov 25, 2015
