Abstract

The invention provides a method for detecting a cooling hole of a combustion gas turbine blade. The method sequentially comprises the steps of firstly, injecting liquid-state plastic materials into the cooling hole of the combustion gas turbine blade; secondly, preventing the liquid-state plastic materials from flowing, and solidifying the liquid-state plastic materials into a model; thirdly, enabling the model to be separated from the combustion gas turbine blade; fourthly, describing the model. Detection can be carried out on the cooling hole of the combustion gas turbine blade by scanning the model, therefore, more data relative to the position, the size and the shape of the detection can be obtained, and precision and efficiency of measurement are improved at the same time.

Description

technical field [0001] The invention relates to a method for testing cooling holes of a gas turbine blade. Background technique [0002] The static blades or moving blades of gas turbines often work in high temperature and high pressure environments, and their various sizes are extremely important for the good operation of gas turbines, and because they work in a heavy-load environment of hundreds or even thousands of degrees for a long time, these blades will be due to Dimensional changes due to wear. especially for such figure 1 The cooling holes 11 of the gas turbine blade shown are designed to provide passages for the cooling fluid in the inner cavity of the blade, thereby protecting the blades and ensuring their performance and service life. These cooling holes are often small in size and have extremely high requirements on position and inclination angle, etc. Therefore, during production or maintenance, it is necessary to check whether the internal dimensional param...
