A gas turbine is an internal combustion type power machine that uses a continuous flow of gas as a working medium to drive the impeller to rotate at a high speed and convert the energy of the fuel into useful work. It is a rotating impeller heat engine. Combustion chambers and turbines have high operating temperatures, and they also bear the thermal shock caused by drastic temperature changes when the gas turbine starts and stops. Therefore, they are the key components that determine the life of the gas turbine. The need to scan the arc section of the steam turbine to obtain data analysis has problems and improves work efficiency. The use of automated three-dimensional measurement methods can provide suitable solutions.

Practical problems

The gas turbine is large in size, and the arc section that needs to be inspected cannot be separated. The arc of the section is large, which brings difficulty to the traditional inspection work, and the customer requires that the inspection speed is fast.

A detailed scan of the gas turbine site

Gas turbine arc section detection uses Hualang 3D HL-Scan 3D online detection system combined with the latest 3D scanning technology to perform effective data scanning of gas turbines. The process does not need to stick or spray powder. It is easy to operate, grab and scan, and handheld to facilitate mobile scanning. The scanning speed is fast, the precision is high, and the high-precision three-dimensional data can be obtained in a short time. It can also cooperate with the robot scanning to reduce manual intervention, realize automatic detection, and improve work efficiency.
