Umehluko we-coefficient yokwandisa okushisayo phakathi kwengxenye ye-granite enembile kanye nengxenye ye-ceramic enembile kanye nokusebenza kwayo kumishini enemba kakhulu
Ekuphishekeleni ukunemba okuphezulu nokuzinza emkhakheni wezimboni, i-coefficient yokwanda okushisayo kwezinto iba ukucatshangelwa okubalulekile. Izingxenye zegwadle ezinembayo kanye nezingxenye ze-ceramic ezinembayo, njengezinhlobo ezimbili zezinto ezisetshenziswa kabanzi kumishini enemba kakhulu, umehluko wabo we-coefficient wokwandisa okushisayo unomthelela omkhulu ekusebenzeni kwemishini.
Umehluko ku-coefficient yokunwetshwa kwe-thermal
Izingxenye ze-granite ezinembile:
I-Granite njengetshe lemvelo, i-coefficient yayo yokwandisa okushisayo iphansi kakhulu, ngokuvamile phakathi kuka-8×10^-6/℃ ~ 10×10^-6/℃. Lokhu kusho ukuthi lapho izinga lokushisa lishintsha, ukuguqulwa kosayizi wengxenye ye-granite kuncane kakhulu, okulungele ukugcina ukuzinza nokunemba kwemishini. Ngaphezu kwalokho, i-granite iphinde ibe namandla amahle okucindezela, ukuqina nokumelana nokugqoka, okwenza kube ibhentshi elisetshenziswa kakhulu lemishini yokunemba okuphezulu, umbhede nezinye izingxenye zezinto ezibonakalayo.
Izingxenye ze-ceramic eziqondile:
Ngokuphambene, i-coefficient yokunwetshwa okushisayo kwezingxenye zobumba ezinembayo iphansi, ngokuvamile iphansi kakhulu kunaleyo yezinto zensimbi njengensimbi engagqwali. Le coefficient ephansi yokunwetshwa okushisayo kwezitsha zobumba ezinembayo iyenza ikwazi ukugcina ukuqina okuphezulu kakhulu nokunemba ngaphansi kokushintsha kwezinga lokushisa okudlulele. Lokhu kubaluleke kakhulu kumishini edinga ukusebenza ngaphansi kwezimo ezinemba okuphezulu isikhathi eside, njengemishini ye-aerospace, amathuluzi okulinganisa ukunemba, njll.
Umthelela kumishini enembayo ephezulu
Ukugcinwa kokunemba:
Emishinini enembayo ephezulu, noma yikuphi ukuguqulwa kosayizi omncane kungaba nomthelela omkhulu ekusebenzeni okuphelele kwemishini. Izingxenye ze-granite ezinembile kanye nezingxenye ze-ceramic ezinembayo, ngenxa ye-coefficient yazo ephansi yokwandisa okushisayo, ziyakwazi ukugcina izinguquko ezincane zobukhulu lapho izinga lokushisa lishintsha, ngaleyo ndlela iqinisekise ukunemba kwesikhathi eside nokuzinza kwemishini. Lokhu kubaluleke kakhulu kumishini edinga ukunemba okuphezulu, okufana nemishini yokulinganisa yokuhlanganisa, imishini ye-lithography, njll.
Ukwenza okufanayo:
Emishinini enembayo ephezulu, ukufana phakathi kwezingxenye ezihlukene nakho kungenye yezinto ezibalulekile ezithinta ukusebenza kwemishini. Ngenxa yomehluko ku-coefficient yokwanda okushisayo phakathi kwezingxenye ze-granite ezinembayo kanye nezingxenye ze-ceramic ezinembayo, lo mehluko udinga ukucatshangelwa ngokugcwele enqubweni yokuklama neyokukhiqiza ukuze kuqinisekiswe ukufana okuhle phakathi kwezingxenye. Isibonelo, lapho kuhlanganiswa izingxenye ze-ceramic ngokunemba nezingxenye zensimbi, izindlela ezikhethekile zokuxhuma nezinto zokwakha ziyadingeka ukuze kuncishiswe ukugxilwa kwengcindezi kanye nezinkinga zokuguquguquka okubangelwa ukuhluka kwama-coefficients okwanda okushisayo.
Uhlelo lokusebenza oluphelele:
Ekusetshenzisweni okungokoqobo, izingxenye ze-granite ezinembayo kanye nezingxenye ze-ceramic ezinembayo zivame ukukhethwa futhi zisetshenziswe ngokuya ngezidingo ezithile. Isibonelo, kumathuluzi okulinganisa okunemba okuphezulu, izingxenye ze-granite ezinembile zingasetshenziswa njengebhentshi lomsebenzi kanye nezinto zombhede ukuze kuqinisekiswe ukuzinza nokunemba kwemishini; Ngesikhathi esifanayo, ezingxenyeni ezidinga ukunemba okuphezulu kanye nezinguquko ezincane zobukhulu, izingxenye ze-ceramic ezinembile zingenziwa. Lolu hlelo lokusebenza oluphelele lunganikeza ukudlala okugcwele kuzinzuzo zezinto ezimbili futhi luthuthukise ukusebenza okuphelele nokuthembeka kwemishini.
Kafushane, umehluko ku-coefficient yokwandisa okushisayo phakathi kwezingxenye ze-granite ezinembayo kanye nezingxenye ze-ceramic ezinembayo kunomthelela obalulekile ekusetshenzisweni kwemishini enemba kakhulu. Ngokukhetha okunengqondo nokusetshenziswa kwalezi zinto ezimbili, singakwazi ukuqinisekisa ukuthi okokusebenza kusengagcina ukunemba okuphezulu nokuzinza endaweni yokuguquka kwezinga lokushisa, ukuze kuhlangatshezwane nezidingo zemishini ehlukahlukene enembayo nokulinganisa.
