What is the advantage of using a labyrinth seal?

In areas of high airborne particulate matter or heavy washdown areas, a labyrinth-style seal can help limit the ingress of contaminants and prolong machine life. With proper lubrication and contaminant-exclusion devices, many bearings can come close to achieving their design life.

Where are labyrinth seals 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.

How does a labyrinth seal prevent leakage?

Similarly, if the labyrinth chambers are correctly designed, any liquid that has escaped the main chamber becomes entrapped in a labyrinth chamber, where it is forced into a vortex-like motion. This acts to prevent its escape, and also acts to repel any other fluid.

How does a duo cone seal work?

They apply the axial pressure to the seal faces and form an effective seal in the housing. They also prevent the seal ring from turning with the shaft. The seals are installed so that one seal is stationary while the other rotates. The lapped sealing faces slide against each other on a thin film of lubricant.

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.

How many seal rings make up a duo cone seal?

two
These seals are comprised of two metal faces (which is why they are sometimes called floating face seals) and two flexible toric rings that forces those faces together so that they form a tight seal.

What is a floating seal?

Floating seal is a seal used in a rotating body exposed to silt and sand. The floating seal is a kind of a combination seal composed of high hardness cast-iron seal rings and rubber O-rings. This seal, because its metal seal rings slide across each other, has great durability against the wear by silt and sand.

What is labyrinth in steam turbine?

The function of all labyrinth seals inside the steam turbine, at each turbine stage, is to reduce steam leakage between stator and rotor parts and returning leaked steam in main steam flow (main steam flow passes through channels between all stator and rotor blades at each turbine stage).

What is a labyrinth oil 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 a labyrinth seal compressor?

Labyrinth sealing (click to enlarge) The Laby® is a vertical in-line reciprocating compressor with a simple and rugged compressor design including two features which make the Laby® unique. The unique technology is applied between the piston and the cylinder wall and between the piston rod gland and the piston rod.

What is a labyrinth ring?

Ring of the Labyrinth. The Ring of the Labyrinth is an optionally unlocked guild located in Athlum, Elysion, and Ghor (in Ghor it is called the Ring of the Ancient Castle ).
