System belongs to turbocompressor preparation technical field.
Background technique
Turbocompressor is for improving gas pressure and conveying the machinery of gas, is to have moving for high-speed rotating impeller
Power formula compressor improves gas pressure by the interaction force between rotary blade and air-flow, while generates air-flow and adding
Speed and obtain kinetic energy, then air-flow slows down in diffuser, converts kinetic energy into pressure energy, further increases pressure, is pressing
Gas flowing is continuous in compression process.It, which is widely used in various technical process, conveys air and various gases, and improves it
Pressure, while gas temperature also correspondinglys increase.By multistage-combination, also there are intercooled multistage combination or even multi-cylinder combination
Compression obtains final pressure required for gas.Impeller in turbocompressor is the mostly important component of whole equipment, works as pressure
When contracting machine is run under design conditions, air-flow flowed in runner it is smooth, with geometric dimension no-float, airflow direction and blade
Geometry established angle it is consistent, the work coordinations at different levels of compressor at this moment, overall efficiency is high.And when blade exists and damages, meeting
Making compressor, air-flow flowing is abnormal in the process of running, causes compressor performance can be greatly reduced, there is also pressure when serious
Contracting machine rotor and stator are subjected to alternate stress effect and are broken, and keep interstage pressure not normal and cause judder.Cause sealing and
Damage of thrust pad；So that motor element and stationary element is collided, causes major accident.
Blade is also easy to produce fracture and crackle equivalent damage problem under high speed rotation in turbocompressor.In turbocompressor
In actual use, since turbocompressor blade inlet port is impacted by impurity and root of blade is corroded etc. draws
It plays material surface and generates microdefect, eventually lead to blade and generate fatigue fracture under the action of reversed torsion power.As a result, in order to
Guarantee turbocompressor stable operation, needs accurately to obtain crop leaf measuring data.
Currently, when carrying out test of flaw detection to blade ultrasound examination, consumption need to be carried out to rotor by manually mode
Take a large amount of man power and material, this not only large labor intensity, detection cycle is longer, and for the rotor that blade assembly is completed
When In-service testing, manual detection mode can not then be implemented.
