What’s a labyrinth seal?

[ad_1]

A labyrinth seal is a complex seal that creates a difficult path for liquids to pass through, used in various settings on rotating or moving objects. It has grooves that distribute pressure and reduce friction, and can withstand harsh conditions. It keeps contaminants out and materials in, and replacements can be found at hardware stores.

A labyrinth seal is a seal that creates a complicated path for liquids to pass, making it difficult for liquids to pass through the barrier created by the seal because they have difficulty making their way through the labyrinth. These types of seals are used in a variety of settings and can be used on objects that rotate or otherwise move. In fact, the movement can make the labyrinth seal even more effective, depending on the design.

The labyrinth seal has a series of grooves that interlock with other grooves or teeth. This differs from most traditional gaskets, which use a single lip in an attempt to seal an opening. With the labyrinth seal, each groove acts as its own lip, distributing pressure across the seal instead of concentrating it in one area. While a labyrinth seal cannot handle high pressure differentials, it can be used in many other types of environments.

Seals are used to keep substances such as grease and lubricants inside, while keeping dirt, fluids and other contaminants out. An advantage of this type of seal is that when small leaks occur through the seal, as is unavoidable, contaminants from the outside still cannot get all the way into the interior and the materials to be sealed may not make their way all the way into the seal. other end. This minimizes fouling caused by mixing contaminants and sealed fluids.

The labyrinth seal design also reduces friction, making it suitable for devices such as turbines. These seals can withstand conditions that might cause other seals to break, and as long as they’re well maintained, they should hold up very well. Materials such as plastics that are less likely to corrode than metals can also be used to create a labyrinth seal, giving the seal a longer life. Specialty products for particular applications may be made with rare or precious metals and other unusual components believed to perform better.

Replacements for labyrinth seals that wear out or become compromised can be obtained at hardware stores and through companies that stock replacement parts for various types of equipment. It’s important to confirm that a replacement is designed to fit, as variations in design can create weaknesses in the seal that will make it less effective. Some labyrinth seals may be stamped with a specific part number which can be used as a reference when picking up a replacement.
