Overview
技术，工程能力和监管要求一直在不断发展，并且有许多方法可以使老化的涡轮机械性能更符合当前标准。
我们经验丰富的人员不断开发和整合新技术，以最经济的方式提高设备的生产率。结果是广泛的转换，修改和升级（CMU）解决方案，可改善客户安装设备的可用性，可靠性，排放，生产率和生命周期成本。
We've successfully executed over 1,500 CMU projects around the globe. Working closely with customers, our engineers have developed solutions to optimize the production of upstream sites, produce more LNG, transport more gas through pipelines, increase the output of refineries and petrochemical plants, and much more. With short payback cycles, our proven CMU solutions are the most effective ways to improve the value of your assets.
As the original equipment manufacturer (OEM), we have the best knowledge and experience to assess the feasibility of various options that could be applied to your equipment; and our dedicated engineering team is at your disposal to help identify the best choice.
以下只是我们提供的许多CMU的一些示例。
DLE 1.5 upgrade to reduce emissions for LM2500 and LM2500+ turbines
Advanced combustion technology from our LM2500+G4 engine (including upgraded design, materials, coatings, and enhanced cooling) is integrated into the installed LM2500 base engine or LM2500+ turbine (SAC and DLE 1.0 versions of both). It reduces NOx emission from 25 ppm to 15 ppm, and CO2 to 25 ppm—and can be extended in some cases down to single-digit emissions. Automapping is also available for several engine models.
PGT25+G4 airfoil upgrade for better performance in hot and cold ambient conditions
Engines are typically designed for best performance at ISO conditions, but many installed units actually operate at hotter or cooler ambient conditions. Changing airfoil profile makes it possible to optimize performance at a specific ambient temperature. Our engineers can study your operating conditions to identify the improvement potential, and then we can redesign and produce low-pressure turbine (LPT) airfoils to obtain new tent curves.
LM2500和LM2500+的热门维护扩展升级
我们利用LM2500+ G4的高级热门技术用于安装的LM2500基本发动机或LM2500+（SAC，DLE 1.0和DLE 1.5版）。它包括升级的材料，可用于高应力和温度抗性，涂料和增强的次要冷却，以及创新的新数字控制功能。该解决方案将热门部分的维护间隔从25,000小时的工作时间扩展到5万小时，可降低运营成本并增加单位寿命。
高效阶段
We can replace the 2nd and 3rd stage blades of your reaction turbine with newly designed blades with improve aerodynamics. Case studies show an efficiency increase of about 2% overall, and above 2.3% for the single drum.
密封技术更换（效率和内在安全性）
我们最新的后弹簧密封件可以使用较短的维护时间安装，因为更换刀片载体的更换使用更快的重新组装程序。不需要额外的加工，并且不需要卸下转子和刀片载体。
我们的可覆盖密封可改善涡轮机的可维护性与传统条纹密封迷宫密封，您可以预计蒸汽消耗量会降低0.4％至1％。
Comparted to J-strips, our brush seals reduce leakage on balancing or recovery drums. They deliver an efficiency increase of 1-2 points, depending operating conditions.
气门执行器电气化（可靠性，简化和连接）
We provide both electro-hydraulic and electro-hydrostatic valve controls.
The hydraulic option features:
- Precise position control and fast response time
- 冗余线性变量变压器（LVDT）位置传感器
- High tolerance to contaminants, operates on oil filtered to 24–40 microns
- 有限的硬件修改，没有手动站点校准
静液压选项的优势包括：
- 简化软件包
- 减轻体重和足迹
- Plug-and-play—no separate items for field assembly or installation
高效阶段技术
Development of the core impeller is the key to improving performance. Our impellers portfolio covers all service requirements, and is continually evolved and updated based on extensive analysis of data from tests and our global installed base. The results are exceptional performance and predictability.
热塑性迷宫密封以提高效率
普通的金属密封件设计具有大量的间隙，以避免在操作过程中与旋转元素接触。由于与气体污染物（例如氯化物，汞和酸性环境）的腐蚀相互作用，一些金属材料通常会降解。
由于创新的材料，我们可以改进的迷宫密封系统降低了间隙，该材料可确保在两种表面的短暂或长时间接触的情况下得到更好的响应。该系统可以由增强的PEEK，PEK，PAI或VESPEL CR-6120制成。它可以提高可靠的多变态效率，并且与恶劣的环境兼容。
可擦的密封
由于与气体污染物（如氯化物，汞和酸性环境）相互作用而导致的一些金属材料降低。
We therefore offer a teeth-on-rotor (TOR) design with statoric seal in abradable material compatible with extreme ambient conditions. : Al-based METCO601 thick coating is compatible with all environments except mercury, and has no temperature limitations. MICA-filled PTFE (e.g. Fluorosint 500®) is compatible with harsh environments including sour and acid gas, mercury, and chlorides. Our design also minimizes gap leakages, and delivers proven polytropic efficiency increases.
高效率缸阀
我们最新的气缸阀的形状是减少气压损失的形状，并且随着几何流量增加而增加的环。气门座椅和防护设备，较低的冲击速度以及弹簧上的较低替代应力以及避免弹簧线圈和阀门守卫之间接触的新弹簧盖的较低的替代应力。该设计使效率高达40％，更长3倍，并提高可靠性。
New internal parts kit for cylinder
The kit includes new cylinder head, spacer and valve cages. Features include:
- 提高吸力和排放流道的形状
- Reduced dynamic pressure losses
- Improved compressor efficiency
新的气缸技术
我们的新圆柱设计对工艺气路径的效率进行了优化。气缸盖和衬里垫片的改性形状可产生从阀到孔的平滑通道。优化的水夹克降低了水流并提高冷却效率，我们使用了结节性铸铁（NCI）而不是铸钢（CS）材料。我们还通过一些最好和最受信任的铸造厂的共同设计协助优化了铸造过程。这些增强功能结合在一起，以提供更高的压缩机效率。
