1 de ene. de 2022 · Table 15.1 shows sealing structures and leakage control technologies used in sealing designs for steam turbines classified by leakage locations and categories. Labyrinth seals and seal fins have been used as sealing structures for rotor blade tips, stator blade tips (nozzle diaphragm inner rings), glands (shaft-end packing seals), and so on as classic essential sealing elements.
1 de nov. de 2023 · The labyrinth consists of two parts: a static seal connected to the turbine covers and a rotating part connected to the runner. The labyrinth gap is small for a new turbine and so the leakage is low.
Sealed ideally: Labyrinth seals for higher turbine efficiency. Due to their construction on both the fixed and rotating part of the turbine, ... L-seal, J-seal or custom-Made: labyrinth seal shapes . L-shaped labyrinth seal. Thickness from 0.01 to 0.3 inches; Diameter from 4.7 to 240 inches; Height / segments from 0.1 to 0.8 inches;
30 de nov. de 2023 · Abstract. This paper presents a study conducted on a new gas turbine designed to limit leakage in the labyrinth seal. The slots in the fin are used to generate a bypass flow, which obstructs the flow in the gap above the fin. The method was tested numerically and experimentally beforehand using a simplified model without rotation or blade passages. In this paper, the validation of the method ...

FUNCTION AND SYSTEM LAYOUT The two functions of the turbine glands and seals are:1 To prevent or reduce steam leakage between the rotating and stationary components of the turbines if the steam pressure is ... gland can withstand higher steam conditions than the carbon ring gland. Figure 9.1 ( a) illustrates a simple form of a labyrinth seal.
