概述
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。
Our experienced personnel continually develop and integrate new technologies that increase equipment productivity in the most economical ways. The result is a wide range of conversion, modification and upgrade (CMU) solutions that improve the availability, reliability, emissions, productivity, and lifecycle costs of our customers' installed equipment.
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.
Below are just a few examples of the many CMUs we offer.
DLE 1.5 upgrade to reduce emissions for LM2500 and LM2500+ turbines
我们的LM2500+ G4发动机（包括升级的设计，材料，涂料和增强冷却）的高级燃烧技术已集成到已安装的LM2500碱发动机或LM2500+涡轮机（两者的SAC和DLE 1.0版本）中。它将NOX发射从25 ppm降低到15 ppm，而CO2降低到25 ppm，在某些情况下可以将其延长至单位数排放。自动化也可用于多种引擎型号。
PGT25+G4机翼升级可在冷热环境中更好地性能
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
We utilize advanced hot section technology from the LM2500+G4 for an installed LM2500 base engine or LM2500+ (SAC, DLE 1.0 and DLE 1.5 versions). It includes upgraded materials for high stress and temperature resistance, coatings, and enhanced secondary cooling, as well as innovative new digital control features. This solution extends maintenance intervals for the hot section from 25K hours of duty up to 50K hours, reduces operating costs, and increases unit life.
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.
Sealing technology replacement (efficiency and intrinsic safety)
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％。
我们的刷密封被固定在J-strips上，减少了平衡或恢复鼓的泄漏。他们的效率提高了1-2点，具体取决于操作条件。
Valve actuator electrification (reliability, simplification and connectivity)
我们同时提供电溶解和电静电瓣控制。
液压选项功能：
- 精确的位置控制和快速响应时间
- 冗余线性变量变压器（LVDT）位置传感器
- 对污染物的高耐受性，在过滤至24-40微米的油上运行
- 有限的硬件修改，没有手动站点校准
Advantages of the hydrostatic option include:
- 简化软件包
- Reduced weight and footprint
- 插件 - 没有用于现场组装或安装的单独项目
High-efficiency stage technology
核心叶轮的开发是提高性能的关键。我们的叶轮投资组合涵盖了所有服务要求，并根据对测试和我们的全球安装基础的数据的广泛分析不断发展和更新。结果是出色的性能和可预测性。
Thermoplastic labyrinth seals to improve efficiency
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。
Our retrofittable labyrinth seal system has reduced clearance thanks to an innovative material that guarantees a better response in case of transient or prolonged contact of the two surfaces. The system can be made from reinforced PEEK, PEK, PAI or VESPEL CR-6120. It delivers a proven polytropic efficiency increase, and is compatible with harsh environments.
Abradable seals
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.
High-efficiency cylinder valves
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
- 减少动态压力损失
- 提高压缩机效率
New cylinder technology
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。
