LITŠOANTŠISO TŠOANE

Ho Nangong Forging, re motlotlo ho fa bareki ba rona lihlahisoa tsa boleng bo holimo tse ferekaneng. Ho latela boitseanape ba rona bo pharaletseng ba theknoloji ea metallurgy le forging, re thehile mefuta e mengata ea phetiso ea boleng bo holimo e netefalitsoeng ho fihlela litlhoko tsa hau tse ikhethileng le ho feta tebello ea hau.

Lisebelisoa tsa rona tsa phetisetso li entsoe ka thepa ea boleng bo holimo feela 'marakeng. Re sebelisa lisebelisoa tse kang 42CrMo4, 36CrNiMo4, 30CrNiMo8, 25CrMo4 hammoho le likhetho tsa tšepe tse sa hloekang ho kenyelletsa 301, 316, 316L, 17-4 le 15-5. Lisebelisoa tsena li khethiloe ka hloko bakeng sa matla a ikhethang le ho tšoarella, ho etsa bonnete ba hore lihlahisoa tsa rona li ka mamella lits'ebetso tse batloang haholo tsa phetisetso.

Re motlotlo ho fana ka lisebelisoa tsa rona tsa boleng bo phahameng tsa metallurgical forgings tse etselitsoeng ho kopana le ho feta litebello tsa indasteri ea hau. E entsoe ka mefuta e fapaneng ea lisebelisoa tsa boleng bo holimo, ho kenyeletsoa 17NiCrMo6-4, 18CrNiMo7-6, 42CrMo4, 36CrNiMo4, 30CrNiMo8, 25CrMo4, 24CrMo5 le 12Cr13, liqapi tsa rona li tsebahala ka ho tšoarella ha tsona le ho sebetsa ka matla.

Feme ea rona ea forging ke moetsi ea etelletseng pele ea ikhethileng tlhahisong ea likheo tsa lisebelisoa tsa boleng bo holimo tsa turbine ea moea. Likheo tsa gearbox tsa moea tsa turbine ke likarolo tse ikhethang tse tlamehang ho fihlela litlhoko tse thata tsa ts'ebetso.

Theko e kholo ea turbine ea moea ea sehlopha sa MW ke karolo ea bohlokoa ea litsamaiso tsa phepelo ea matla a moea. E bapala karolo ea bohlokoa ho fetisetseng matla a ho potoloha a turbine hub ho jenereithara, 'me qetellong e fetole matla a kinetic a moea ho ba motlakase. Li-shafts tsa rona tse ka sehloohong li etselitsoe ho mamella maemo a thata ka ho fetisisa a moea, ho fana ka botšepehi le bokhoni bo phahameng.

Lehare la turbine ke radial aerofoil e kentsoeng rim ea turbine disc mme e hlahisa matla a tangential a potolohang rotor ea turbine. E 'ngoe le e' ngoe ea turbine disc e na le li-blades tse ngata. Ka hona, li sebelisoa lienjineng tsa turbine tsa khase le li-turbine tsa mouoane. Li-blades li na le boikarabelo ba ho ntša matla ho tloha mocheso o phahameng, khase e phahameng ea khatello e hlahisoang ke combustor. Hangata li-blades tsa turbine ke karolo e fokotsang ea li-turbine tsa khase. Ho phela tikolohong ena e thata, li-blades tsa turbine li atisa ho sebelisa lisebelisoa tse sa tloaelehang tse kang li-superalloy le mekhoa e mengata e fapaneng ea ho pholisa e ka arolelanoang ka hare le ka ntle, le liphahlo tse thibelang mocheso. Mokhathala oa lehare ke mohloli o moholo oa ho hloleha ha li-turbine tsa mouoane le li-turbine tsa khase. Mokhathala o bakoa ke khatello ea maikutlo e bakoang ke ho thothomela le molumo oa molumo ka har'a mefuta e mengata ea mechine. Ho sireletsa li-blades likhatellong tsena tse matla tse matla, ho sebelisoa li- dampers tsa likhohlano.

turbine ea mouoane e na le rotor e lutseng holim'a li-bearings 'me e kenngoe ka har'a casing ea cylindrical. Rotor e fetoloa ke mouoane o phunyeletsang khahlanong le li-vanes kapa li-blades tse khomaretsoeng tseo ho tsona li sebelisang matla ka tsela e tsitsitseng. Ka hona, turbine ea mouoane e ne e ka talingoa e le letoto le rarahaneng la litlhophiso tse kang leloala la moea, kaofela li bokane holim’a shaft e le ’ngoe. Ka lebaka la bokhoni ba eona ba ho hlahisa matla a maholo ka har'a sebaka se batlang se le senyenyane, turbine ea mouoane e phahametse lisebelisoa tse ling tsohle tse ka sehloohong, ntle le li-hydraulic turbines, bakeng sa ho hlahisa motlakase o mongata le ho fana ka matla a matla bakeng sa likepe tse kholo, tse lebelo le phahameng. ke karolo e bohareng ea koloi ea motlakase. The rotor shaft ke carrier shaft bakeng sa motsoako oa laminated oa rotor 'me kahoo o fetisetsa torque e hlahisoang ke motlakase ka khokahanyo e nepahetseng ea ho tsamaisa. Ha e le hantle ke ntho e sebelisoang mochining o etselitsoeng ho hlahisa matla a tsoelang pele. Mokhoa oo o sebelisoang ho oona o ntša matla ho tsoa phallong ea mokelikeli ebe o o fetola ka mokhoa o ka sebelisoang kapa o mahareng. Li-shaft tsa rotor li boetse li sebelisoa likarolong tse ngata tse kholo le tse tloaelehileng tsa boenjiniere, tse kang ho hlahisa matla le merafo. Ke likarolo tsa bohlokoa lifemeng tse ngata tse fehlang motlakase 'me hangata li na le boholo bo boholo le matla.Lithuto tse kholo tsa li-tubine rotor shafts tseo re li hlahisitseng pele ke:
