TRENDS IN THE DEVELOPMENT OF METHODS FOR DIAGNOSTICS OF THE TECHNICAL STATE OF THE BLADES OF GAS-PUMPING UNITS

Keywords: gas-pumping units, blades, diagnostics, method, technical condition, classification, diagnostic feature

Abstract

Object of research: degradation processes occurring in the blades of a gas-pumping unit (GPU) during its long-term operation and cause the appearance of defects that lead to a change in their technical condition and breakage of the working blades and, as a result, to accidents.

Solved problem: obtaining a method for diagnosing the GPU blades, which can be used to determine its technical condition during the GPU operation.

The main scientific results: a classification of methods for diagnosing the GPU blades and their analysis was developed, according to the results of which it was established that the improvement of a new method of aerodynamic calculation of profiles relative to the GPU blades by developing mathematical models of the deformation process and flow around the GPU blades and calculation formulas for assessing their aerodynamic characteristics, will allow to simulate possible options for changing the technical state of the blades (the amount of wear of the blades, their number, deformation, etc.), to study their influence on the parameters of the oscillatory processes of the blades and to compile a dictionary (base) of diagnostic signs of their state. The use of such a base will make it possible to quickly determine the technical condition of the blades during the GPU operation and prevent the occurrence of emergency situations

The area of practical use of the research results: the enterprises of the gas transmission system, which operate GPU with a gas turbine drive

An innovative technological product: a method of direct aerodynamic calculation of airfoils relative to GPU blades to determine their technical condition during operation.

Scope of application of the innovative technological product: gas-pumping units with a gas turbine drive with a capacity of 6.3 MW to 25.0 MW
