Overhaul of Gas Turbines (Including Disassembly, Inspection of Parts, Manufacturing of Auxiliary Parts, Balance and Assembly)
Application:
Electricity generation and mechanical engine of rotating equipment
Product Introduction:
SGT400 can be introduced as the smallest gas turbine on a power plant scale (made by Siemens, Germany) in which a two-variable turbine is considered. The first turbine of this type with a rated power of 9.13 MW was released in 2000. In 2008, it was introduced as a package and as a mechanical motor for rotating
equipment, and its upgraded version with a rated power of 15 megawatts was delivered to the market. The use of the IGV system in the first five stages of the compressor is one of the features of this gas turbine. This feature provides different working conditions with the best efficiency and is designed and built for both the needs of electricity generation and mechanical engine of rotating equipment. Rebuilding a gas turbine after a certain period of operating requires dismantling all its parts.
Technical Specifications:
During the overhaul of this turbine, before the disassembly of the turbine, the overall condition of the turbine is checked using a borescope. After preparing a report on the condition of the delivered turbine before disassembly, the turbine shell (turbine nozzle and diffuser) is first separated from it; Next, the three parts of compressor, combustion chamber and turbine are disassembled from the main shaft. Then the sub-systems such as exhaust, accessory drive, combustion chamber are disassembled and also in order to rebuild the compressor, liners, movable blades and compressor discs will be disassembled separately. After disassembly for initial inspection, the parts are washed and cleaned. Next, the parts are subjected to preliminary examination to determine whether they need to be replaced or not. After receiving repair parts and preparing replacement parts, parts and systems are reassembled. In the meantime, the blades on the discs are aligned and balanced, and each one is assembled on the balanced shaft based on the Run Out.
