Sealing Without Gas Swirl
Honeycomb seals are machined with individual chambers that create the pressure drop needed to slow leakage. Those chambers also disrupt circumferential flow around the shaft, preventing destabilizing forces caused by the gas swirl that is common with labyrinth seals.
honeycomb seals are engineered using a bulk-flow analysis tool to model the steady state and dynamic performance, optimized for the specific application. Key metrics that are optimized include the required leakage and dynamic coefficients, which are evaluated in a complete rotordynamic analysis of the rotor-bearing system.
From Aerospace to the Industrial Market
Honeycomb seals were initially used in the aerospace industry in air-breathing gas turbine engines as abradable stator components for high-pressure turbine stages. Later, they were used in cryogenic rocket engine turbopumps as a damper seal at the balance piston location.
Eventually the technology was adopted by the industrial market, which primarily focused on applications in high-pressure centrifugal compressors.
Honeycomb seals can be manufactured from a range of materials, including stainless steel, aluminum and plastic - the last allowing for an even tighter clearance.
we have provided national aircraft-building companies with honeycomb seals strips for all engine types manufactured in the country, thus eliminating the dependence on import deliveries.We produce materials complying with the requirements of leading worldwide gas turbine manufacturers, such as General Electric, Rolls-Royce and Safran.We know our business, we are responsible for the quality and are happy to have new partners!
