Embodiment Construction

[0020] See below figure 1 , A cross-section of the axial flow steam turbine 10 is shown, which includes a casing 12 and a rotating shaft 14. A plurality of turbine blades 16 are fixed to the shaft 14 in a conventional manner and rotate therewith. The inlet diaphragm 18 includes a circular row of blades 20 that can accelerate and guide the steam from the steam chamber 22 to the first row 24 of turbine blades.

[0021] Another diaphragm 26 is provided between the blade pairs of the lower stage of the turbine blade 16 to accelerate and change the direction of the steam from the upper stage, and hit the next stage at an optimal angle and speed.

[0022] Each diaphragm 26 includes a blade 20 between an outer gasket 28 and an inner gasket 30. An outer ring 32 is fixed to the outer gasket 28, and the outer ring cooperates with the housing 12 in a conventional manner. An inner ring 34 is fixed on the inner washer 30, and the inner ring is suspended from the above-mentioned shaft 14 at in...

Abstract

A method and system of constructing equivalent integral covered blading for a turbine having multiple blades supported by a stator include multiple blade foils; multiple respective cover portions defining a first surface configured to span tips of multiple adjacent blades between tip locations of adjacent blades thereby to form the cover portion portions for adjacent blades and wherein the cover portions associated with each respective adjacent blades include facing sides for adjacent cover portions of adjacent blades; and an overcover coupled to a second surface opposite the first surface of the respective cover portions, the overcover configured to at least one of stiffen deterministic constraints of the tips and seal against leakage through the facing sides for adjacent cover portions.

Description

Technical field [0001] The invention relates to a steam turbine, in particular to a fixed bearing member or an inner shell containing guide blades, which guide and accelerate steam for impacting the bucket blades of the steam turbine. Background technique [0002] A steam turbine usually uses a guide formed by a plurality of aerodynamic fixed blades to receive steam in the steam path, and smoothly turn it into a desired direction and accelerate to impinge on the turbine blades. The accuracy of the steam path is very important for turbine efficiency. The steam must be guided very accurately by using a precisely structured and stable supporting diaphragm or guide vane to avoid wasting power turbulence or deviating from the designed flow characteristics. [0003] Some steam turbine design concepts use diaphragms, which are traditionally formed by inserting the opposite ends of the blades into cutouts in a semi-circular belt as a gasket. The ends of these blades are pre-welded to the...
