carbon rings for steam turbines rings

• conventional: carbon rings – conventional practice – 4 to 5 rings typical – tight clearance – easy to install – wear easily • upgrade: mechanical seals – low leakage – alignment sensitive – sensitive to “wet” steam. 5. carbon rings mechanical seals
Feb 22, 2007 · steam leakage through labyrinthsteam turbine. once the turbine is running, the steam inside turbine at hp will be greater than supplied sealing steam and throttled steam will go accross ring 3 and will provide this source. if the lp secction of the turbine is at vacumn, it will always need a source of sealing steam,...
Major overhauls. a major overhaul is a detailed inspection and overhaul of the entire steam turbine generator set including the turbine casing, rotor, seals, and bearings; the generator; and auxiliaries such as the gear, couplings, lubrication system and controls. an stg should be overhauled every 5 years.
Jul 13, 2018 · for any turbine equipped with carbon rings for packing case seals it is recommended that the carbon rings are run in to ensure proper seating and reduce the possibility of steam leakage.
