Embodiment Construction

[0034] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0035] Such as figure 1 and image 3 Shown, according to the embodiment of the present invention, the present invention provides a kind of seal ring, and this seal ring comprises a plurality of arc segments, and preferably, seal ring consists of six identical arc segments (that is, a complete circular ring Divided into six equal parts) to form a combination, six arc segments connect end to end through six connecting members to form an annular sealing ring, wherein each arc segment includes: a sealing part 10, a first hooking part and a second hooking part . The sealing part 10 is an arc-shaped plate segment, the first hooking part is arranged on the first end of the sealing part 10 , and the secon...

Abstract

The invention provides a sealing ring and a gas turbine with the same. The sealing ring comprises a plurality of arc sections which are connected end to end through connecting components to form the annular sealing ring, and each arc section comprises a sealing portion, a first hooking portion and a second hooking portion, wherein the sealing portions are arc plate sections, the first hooking portions are arranged at the first ends of the sealing portions, and the second hooking portions are arranged on the second ends of the sealing portions. According to the technical scheme, the sealing ring can move along with radial displacement generated by vibration of a rotor, so that blades and the sealing portions of the sealing ring are well protected against damage, and the service life of the sealing ring is prolonged.

Description

technical field [0001] The invention relates to the technical field of gas turbines, in particular to a sealing ring and a gas turbine with the same. Background technique [0002] The turbine rotor of a gas turbine is a high-speed rotating part, and a certain rotation gap must be maintained between the tip of the rotor blade and the inner wall of the casing to prevent the tip of the rotor blade from colliding with the inner wall of the casing when the blade is rotating causing damage to the leaves. However, excessive rotation clearance will cause gas leakage, thereby reducing the working performance of the gas turbine. Therefore, the setting of the rotation clearance cannot be too large, but the leakage of gas should be minimized. [0003] In order to ensure the working performance of the gas turbine, the existing gas turbines all use a special sealing device to prevent the gas from leaking from the tip of the rotor blade and the inner wall of the casing. The grinding sur...
