Gasi turbine tsika superalloy turbine blades
Gasi turbine blade
Iyo kambani ine yakanaka yemhando yekudzora timu, yakanakisa yekuyedza tekinoroji, yepamusoro yekugadzira uye yekuyedza michina uye yakapfuma ine ruzivo rwehunyanzvi timu.Iyo kambani ine mukurumbira wakanaka uye inogara kwenguva refu kubatana kwakanaka nevagadziri vanozivikanwa kumba nekune dzimwe nyika.
Izvo zvakakosha zvegasi turbine blades ndezvi:
1. Nyaya yacho ine zvinhu zvinodhura zve superalloy;
2. Kuita kwakashata kwekugadzirisa;
3. Chimiro chakaoma, kunyatsojeka uye pamusoro pemhando zvinodiwa;
4. Kune mhando dzakawanda uye huwandu;
Iwo epamusoro maitiro emablades anosarudza nzira yekusimudzira yekugadzira uye kugadzira blade: kuronga hunyanzvi kugadzirwa;Yepamberi isina chinhu yekugadzira nzira ine zvishoma kana kusachekwa inogamuchirwa kuvandudza chigadzirwa mhando uye kuchengetedza yakakwirira tembiricha inodzivirira zvinhu;Adopt otomatiki uye semi-otomatiki anoshanda muchina maturusi, ronga otomatiki mitsara yekugadzira yekuyerera kuyerera, uye zvishoma nezvishoma tora kudzora nhamba uye komputa tekinoroji yekugadzirisa.
Sezvatinoziva tose, mashizha mumagetsi emagetsi ndiwo "moyo" we turbomachinery uye zvikamu zvakakosha mu turbomachinery.Turbine imhando yemagetsi anotenderera emagetsi emagetsi, ayo anotamba zvakananga basa rekushandura kupisa kwesimba rechiutsi kana gasi kuita magetsi emagetsi.Mablades anowanzo shanda pasi pekushisa kwepamusoro, kudzvanywa kwakanyanya uye svikiro rinopisa.Mashizha anofamba anotendererawo nekumhanya kukuru.Mumaturbine makuru ehutsi, kumhanya kwemutsetse wepamusoro peblade kwapfuura 600m/s, saka blade inotakurawo kushushikana kukuru kwecentrifugal.Nhamba yemashizha haisi yakakura chete, asiwo chimiro chakaoma, uye zvinodiwa zvekugadzirisa zvakasimba;Basa rekugadzirisa basa remablades rakakura kwazvo, rinoverengera chikamu chimwe kusvika kuchikamu chimwe muzvitatu chehuwandu hwekugadzirisa simba remagetsi emhepo uye gasi turbines.The
machining emhando yemablades anokanganisa zvakananga kushanda kwekushanda uye kuvimbika kweyuniti, uye mhando uye hupenyu hwemablades zvine hukama zvakanyanya neiyo machining nzira yemashizha.Naizvozvo, iyo nzira yekugadzira blade ine simba rakakura pamhando yekushanda uye hupfumi hwekugadzira hwema turbine muchina.
Kambani yedu inyanzvi yekugadzira mablades, iine matatu ekunze anotenderedza anotenderedza shanu axis machining nzvimbo, ina inotorwa kunze shanu axis yekubatanidza machining machining, mana akazara otomatiki CNC lathes, matatu Hikscon coordinate detectors, GOM scanners uye akati wandei ebetsero yekuyedza michina.Iyo kambani ine yakasimba tekinoroji timu ine ruzivo rwakapfuma mukugadzira blade, reverse engineering, modelling, programming uye post-processing.
Kune marudzi akawanda emablades, asi marudzi ese emablades anonyanya kuumbwa nezvikamu zviviri zvikuru, zvinoti chikamu chemupfuhwira uye chikamu chepamusoro chegungano.Naizvozvo, iyo blade processing inokamurwawo mukugadzirisa kwenzvimbo yegungano uye kugadzirwa kweiyo steam passage.Chikamu chepamusoro chegungano chinonziwo blade root part Inogonesa kuti blade igadziriswe pane impeller zvakachengeteka, zvakavimbika, zvakarurama uye zvine musoro kuti ive nechokwadi chekushanda kwemaitiro emhepo.Naizvozvo, chimiro uye kurongeka kwechikamu chegungano kuchatemwa zvichienderana nebasa, ukuru, kurongeka kwezvinodiwa zvechikamu chemuputi uye chimiro uye saizi yekushushikana.Sezvo mabasa, zviyero, mafomu uye basa reakasiyana blade steam ndima zvikamu zvakasiyana, kune akawanda marudzi ezvimiro zvezvikamu zvegungano.Dzimwe nguva, nekuda kwezvinodiwa zvekuisa chisimbiso, frequency modulation, kuderedza vibration uye kushushikana, blade inowanzo shongedzerwa jira (kana shroud) uye tie bar (kana damping boss).Iyo shrouds uye braces zvinogona zvakare kuverengerwa senzvimbo dzegungano.Iyo steam passage chikamu chinonziwo chikamu cheprofile, icho chinoumba chiteshi chekushanda kwemhepo inoyerera uye inopedzisa basa iro blade inofanira kuita.Naizvozvo, iyo yekugadziridza kunaka kweiyo steam passage chikamu inokanganisa zvakananga kushanda kweiyo unit.
