My workplace is planning to install a turbine, and I urgently need to understand its structure. I hope that experts can provide diagrams of the turbine’s structure (preferably those showing extraction/condensation systems and multiple valve assemblies), as well as information on the main wear-prone components and key maintenance points. Email: *aochai000@163.com. Thank you all in advance!
