Problems solved by technology

[0005] The performance test of method 1 cannot simulate the multi-parameter environment at the same time and in the same space for real service conditions, so it cannot truly reflect the service conditions of the formed turbine blades in the gas turbine
[0006] Although the performance test of the second method can truly reflect the service conditions of the formed turbine blades in the gas turbine, the test cost is huge and time-consuming

Abstract

The invention discloses a long-time service condition simulation test device for a material for forming a turbine blade. The long-time service condition simulation test device comprises a creep testing machine, a sample assembly, a cooling atmosphere simulation system and an acting atmosphere simulation system, the sample assembly is clamped on the creep testing machine and mainly comprises a sample body, an outer pipe, an upper clamp and a lower clamp, an alloy base material of the sample body is made of a high-temperature alloy material to be tested, an inner hole of the sample body forms a cooling atmosphere simulation cavity, and a working atmosphere simulation cavity is formed between the sample body and the outer pipe; the cooling atmosphere simulation system is used for conveying cooling gas with required pressure, flow and temperature to the cooling atmosphere simulation cavity; the acting atmosphere simulation system is used for conveying fuel gas with required pressure, flow and temperature to the acting atmosphere simulation cavity. According to the invention, the long-time creep property of the material for forming the turbine blade can be tested under the coupling action of factors such as heat, force and chemical factors in the long-time service process, and the service condition of the formed turbine blade in a gas turbine can be truly reflected.

Description

technical field [0001] The invention relates to material service performance testing equipment, in particular to a material used for forming gas turbine blades (turbine blades), and a simulation test device for long-term service working conditions. Background technique [0002] As an important component of the turbine section of a gas turbine, the turbine blade has long served in the extreme working conditions of high temperature and high pressure, and is a typical hot end part of the gas turbine. Since the turbine blade has been in the part with the highest temperature, the most complex stress and the harshest environment for a long time, it is one of the parts with the worst working environment and the most complex structure of the gas turbine, and it is also one of the parts with frequent fracture failures of the gas turbine. [0003] In order to meet the technical requirements of operation, the turbine blades of the gas turbine are provided with flow channels for cooli...
