Ukucaciswa kobuchwepheshe bokwenziwa kwe-shaft enkulu yejeneretha ye-turbine yomoya

1. Ukuncibilika

Insimbi ye-shaft eyinhloko kufanele incibilikiswe kusetshenziswa iziko likagesi, ngokucwengisiswa ngaphandle kwesithando somlilo kanye nokukhishwa kwe-vacuum degassing.

2.Ukuqamba

I-shaft eyinhloko kufanele yenziwe ngokuqondile kusuka kuma-ingots ensimbi. Ukuqondanisa phakathi kwe-axis ye-shaft eyinhloko kanye nomugqa ophakathi we-ingot kufanele kugcinwe ngangokunokwenzeka. Isibonelelo esanele sezinto ezibonakalayo kufanele sinikezwe kuzo zombili iziphetho ze-ingot ukuze kuqinisekiswe ukuthi i-shaft eyinhloko ayinazo izimbobo zokushwabana, ukuhlukaniswa okukhulu, noma okunye ukukhubazeka okuphawulekayo. Ukwenziwa kwe-shaft eyinhloko kufanele kwenziwe kumshini wokubumba onekhono elanele, futhi isilinganiso sokubumba kufanele sibe sikhulu kuno-3.5 ukuze kuqinisekiswe ukubunjwa okugcwele nokufana kwe-microstructure.

I-3.Ukwelashwa kokushisa Ngemva kokubumba, i-shaft eyinhloko kufanele ibhekane nokwelashwa kokushisa okujwayelekile ukuze kuthuthukiswe isakhiwo sayo kanye nokusebenza kwayo. Ukushisela i-shaft eyinhloko akuvunyelwe ngesikhathi sokucubungula nokufaka.

4.Ukwakheka kwamakhemikhali

Umphakeli kufanele enze ukuhlaziya ukuncibilika kweqoqo ngalinye lensimbi ewuketshezi, futhi imiphumela kufanele ihambisane nemithetho efanele. Izidingo zokuqukethwe kwe-hydrogen, umoya-mpilo, ne-nitrogen (ingxenyana yobuningi) ensimbi zimi kanje: okuqukethwe kwe-hydrogen okungadluli ku-2.0X10-6, okuqukethwe komoyampilo okungeqi ku-3.0X10-5, nokuqukethwe kwe-nitrogen okungadluli ku-1.0X10-4. Uma kunezidingo ezikhethekile ezivela kumthengi, umphakeli kufanele enze ukuhlaziya komkhiqizo oqediwe we-shaft eyinhloko, futhi izidingo ezithile kufanele zicaciswe kwinkontileka noma ku-oda. Ukuchezuka ngaphakathi kwemikhawulo evumelekile yokuhlaziywa komkhiqizo oqediwe kuvunyelwe uma kucaciswa yimithetho efanele.

5.Izakhiwo zemishini

Ngaphandle uma kucaciswe ngenye indlela umsebenzisi, izakhiwo zemishini zeshaft eyinhloko kufanele zihlangabezane nezidingo ezifanele. Izinga lokushisa lokuhlola umthelela we-Charpy le-42CrMoA shaft eyinhloko lingu--30°C, kuyilapho ku-34CrNiMoA kushaft omkhulu, lingu -40°C. Ukumuncwa kwamandla okunomthelela we-Charpy kufanele kuqinisekiswe ngokusekelwe ku-arithmetic yezibonelo ezintathu, okuvumela isifanekiso esisodwa ukuthi sibe nomphumela wokuhlola ongaphansi kwevelu elishiwo, kodwa kungabi ngaphansi kuka-70% yenani elishiwo.

6.Ubunzima

Ukufana kokuqina kufanele kuhlolwe ngemuva kokwelashwa kokushisa kokusebenza kwe-shaft eyinhloko. Umehluko wokuqina ebusweni be-shaft efanayo eyinhloko akufanele udlule u-30HBW.

7.Izidingo ezijwayelekile zokuhlola okungabhubhisi

I-shaft eyinhloko akufanele ibe neziphambeko njengokuqhekeka, amabala amhlophe, izimbobo ezishwabene, ukugoqa, ukuhlukaniswa okunzima, noma ukunqwabelana okunzima kokuhlanganisa okungezona ezensimbi okuthinta ukusebenza kwayo kanye nekhwalithi yendawo. Kumashafti amakhulu anezimbobo ezimaphakathi, indawo engaphakathi yembobo kufanele ihlolwe, okufanele ihlanzeke futhi ingabi namabala, i-thermal spalling, ukugqwala, izingcezu zamathuluzi, amamaki okugaya, imihuzuko, noma imigqa yokugeleza okuthandelayo. Ukushintsha okubushelelezi kufanele kube khona phakathi kwamadayamitha ahlukene ngaphandle kwama-engeli abukhali noma imiphetho. Ngemuva kokucisha nokushisa ukwelashwa kokushisa nokuphenduka okungalungile kwendawo, i-shaft enkulu kufanele ithole u-100% we-ultrasonic flaw. Ngemuva kokwenza imishini ngokunemba indawo engaphandle ye-shaft eyinhloko, ukuhlolwa kwezinhlayiya kazibuthe kufanele kwenziwe kuyo yonke indawo engaphandle kanye nobuso bobabili bokuphela.

8.Usayizi wokusanhlamvu

Isilinganiso sikasayizi wokusanhlamvu we-shaft eyinhloko ngemva kokucisha kanye nokushisa kufanele kube mkhulu noma alingane namabanga angu-6.0.
