The diaphragm is used to fix the static blade and divide the cylinder into several chambers. In order to disassemble conveniently, the separator is usually processed into two horizontal parts.
Diaphragm are usually used in impulse steam turbines. They are generally divided into welded diaphragms and cast diaphragms. Reactive steam turbines generally use static blade rings. For example, the majority of Harbin 100 MW, Beizhong, Dongfang and Nanfang steam turbines are impulse type, while the majority of Harbin 300/600 MW, ALSTOM, SAIC and Hangzhou steam turbines are reactionary type.
Scope of application of products
The invention relates to a diaphragm for a 7MW - 1000 MW steam turbine, which relates to a cascade type and a direct welding type.
