Description: Supply and installation of blades, shrouds, assembly materials, labyrinth seals
and the parting plane studs and nuts for the HP cylinder of 30 MW Franco tosi steam turbines at Sitra Power and Water Station.
Kostyuk  performed the first comprehensive analysis for the aerodynamic forces of gas labyrinth seals
excluding the influence of area change due to eccentricity on cross-coupled forces.
To design specific damping characteristics and frequency dependencies, sophisticated approaches use labyrinth seals
which are the focus of this work.
The numerical simulations of the steam exciting force in labyrinth seals
were proposed by Mooree et al.
A high carbon and graphite filled PTFE offers low coefficient of thermal expansion, making it ideal for the manufacture of water turbine bearings and labyrinth seals
. Slightly less carbon graphite (a medium to high filler) won't offer the same thermal expansion properties, but will yield optimum wear rates, making it more beneficial to air compressor applications.
The rollers are engineered to absorb shocks and incorporate high-performance labyrinth seals
to protect the ball bearings from damp and dusty environments.
Sealing of the drive shaft is in the form of wear-free labyrinth seals
. On the output side, the housings are connected to the girth-gear hood by a flexible, oil-tight bridge.
This new line also includes labyrinth seals
on each end of the motor, enhanced sealing around the lead exit, same size bearings on each end and a moisture resistant insulation system.
With the increasing parametric options of the working body of turbomachinery the research questions and rational design of the labyrinth seals
are becoming more relevan, since an increase in initial pressure increases the leakages through all the labyrinth seals
of the machine and reduces the benefits of working medium with high parameters .
When installed correctly, labyrinth seals
will prevent the ingress of both moisture and particle contamination, while retaining lubricating oil.
* Labyrinth seals
around the shaft to meet stringent IP69k ratings.
Through its Qualiseal Technology division it also produces a full range of face seals, labyrinth seals
and mating rings.
