# calculate breaking force of a labyrinth seal

## calculate breaking force of a labyrinth seal

(OP)
How can I calculate the maximum different pressure across a labyrinth, before the knife break away ?

### RE: calculate breaking force of a labyrinth seal

What do you mean by the "knife break away"? sorry but am not familiar with that expression.

Differential pressure is dictated by several factors such as number and geometry of teeth, gas density, clearance, etc.

For further reference, see: Mechanical Design, 2nd Edition, P. Childs - Pub. El Sevier 2004
https://www.elsevier.com/books/mechanical-design/m...

Are you looking at mechanical strength calculations applied to the teeth with respect to a certain Delta P?

(OP)
sorry...terms not standard.
i mean breaking the sharp fins of the labyrinth.

can the fins of the labyrinth break, if the differential pressure is too high ?
