Abstract

The invention relates to the technical field of aero-engines and provides a turbine guide device. The turbine guide device comprises a turbine casing, an orifice plate ring and guide blades. The orifice plate ring is connected to the outer side of the turbine casing. The guide blades are connected to the inner side of the turbine casing. The turbine casing, the orifice plate ring and the guide blades are of an integrated-piece structure. According to the turbine guide device, the turbine casing, the orifice plate ring and the guide blades are arranged to be of the integrated-piece structure, so that the number of parts of the turbine guide device can be effectively lowered, the turbine guide device is simple in structure and high in reliability, and therefore the problem that in the priorart, the turbine guide device is complicated in structure is solved.

Description

technical field [0001] The present disclosure relates to the technical field of aero-engines, in particular to a turbine guide. Background technique [0002] In the existing gas turbine engines and ground gas turbines, the gas turbine guide is one of the important stator parts and flow channel parts. It is located at the front end of the turbine components. Potential energy is converted to kinetic energy. The turbine casing and the turbine outer ring mainly play the role of supporting containment and controlling the blade tip clearance. [0003] Existing gas turbine guides are generally composed of guide vane segments, which are fixed by guide brackets; the turbine outer ring is usually designed in segments, designed as segments with hooks, and connected to the turbine casing through hooks. Since the gas turbine guide and the outer ring of the turbine are combined by sector parts, and the installation bracket of the guide leads to a large number of parts, a large number of...
