Replacing labyrinth seals with brush seals
Featured Product from Technetics Group
BRUSH SEALS
Technetics Group Brush Seals – Designed to increase airflow efficiency in engines and compressors.
Replacing labyrinth seals with brush seals from Technetics Group can reduce leakage by 5 to 17 times, thus providing significant turbomachinery efficiency and output gains.
Brush seals work by absorbing the radial deflections between the shaft and rotor during transient operation. The seal then follows the rotor back to the steady-state operating position to maintain minimum leakage. The brush pack is composed of thousands of finely packed 2.8 to 5.6 mil diameter wire bristles. The bristle material, a cobalt or nickel alloy, is selected to provide an optimal combination of wear properties and oxidation resistance. The backplates and side plates are typically fabricated from stainless steel or nickel alloys. The primary consideration is the thermal expansion and contraction of the case material.
Brush seals can be delivered as a single unit or in multiple segments. The bristles can be configured radially inward, radially outward or axially.
CRITICAL SOLUTIONS FOR COMMERCIAL AIRCRAFT
When an aircraft soars 30,000 feet in the sky, Technetics Group keeps your confidence high. Our critical components are found throughout nearly every section of a commercial airliner from the wire insulation to the APU exhaust, from the gearboxes to accessories. Technetics Group provides critical solutions to assist in pressure regulation, noise control, fluid conveyance and fire protection.
As aircraft design grows increasingly complex, so does your reliance on better and longer lasting aircraft seals and engineered components. At Technetics Group, we meet the most stringent requirements for large and small commercial aircraft, regional and business jets, helicopters and unmanned aerial vehicles.
