The use of optical 3D scanning to localize the production of imported gas turbine equipment parts.

The issue of import substitution is particularly acute now. The development of domestic analogues of imported equipment is in full swing, but the equipment itself must continue to be serviced.

For example, the Swedish Atlas Copco compressor model TP10T22D1 is used in many enterprises that provide regions with electricity and heat, such as Mayakovskaya TPP, Kurgan TPP-2, Yakutskaya GRES-2 and others. The well-being of hundreds of thousands of people depends on the smooth operation of such enterprises, they are elements of critical infrastructure.

Regular replacement of worn parts, such as plain bearings, deflector blades, device guides, and many others, is necessary for compressor maintenance. But their supplies are limited and difficult.

The company's specialists solve this problem DMEnergy, specializing in the maintenance of gas turbine installations, restoration of GTU parts, engineering and supply of basic and consumable components for turbines. And a 3D scanner helps them with this RangeVision Spectrum.

The specialists faced the task of localizing the production of a number of compressor parts, including those where accurate preservation of the original geometry is extremely important to ensure trouble-free operation of the entire device. However, some parts have a complex or curved shape. Measuring them using a hand tool can be time-consuming and too dependent on the human factor. And details of complex shapes and double curvature (such as shoulder blades) are extremely difficult to measure without a 3D scanner.

To simplify and speed up work and improve measurement accuracy, DMEnergy specialists combine traditional methods with the use of an optical 3D scanner.

In total, more than 20 details were scanned. A set of design documentation has been prepared for each of them, with which they can be put into production already in the country. The presence of CD on individual parts of the device simplifies the future full localization of its production in Russia. The use of the scanner significantly reduced the work time.

Judging by the increasing number of requests from a wide variety of industries, 3D scanning is becoming more and more in demand. It is a fast and accurate tool that significantly simplifies and accelerates the process of reverse engineering imported parts and assemblies and, in general, replacing imported equipment with domestic ones.
