Isethulo Esibalulekile Nezinzuzo
Njengokwenziwa kwekristalu kobuchwepheshe besimanje bokukhiqiza ukunemba kwezimboni, i-AISI 316Linsimbi engagqwali utshalomali castingUkwakhiwa kwe-gearbox akubonisi nje ukuthandeka okuyingqayizivele kwe-AISI 316L yensimbi engagqwali, kodwa futhi kufinyelela ukuphindaphinda okunembayo kwezakhiwo eziyinkimbinkimbi ngenqubo yasendulo nenhleukutshala imali. I-AISI 316L insimbi engagqwali, njengelungu le-insimbi engagqwali ye-austeniticseries, igqame phakathi kwezinto eziningi zensimbi engagqwali ngenxa yokumelana nokugqwala okuhle kakhulu, ukumelana nokushisa okuphezulu kanye nezakhiwo ezinhle zemishini. Ikakhulukazi ngemva kokwengezwa kwe-molybdenum, ikhono layo lokumelana ne-pitting, ukugqwala kwe-crevice kanye nokuqhekeka kokugqwala kwengcindezi liyathuthukiswa kakhulu, okwenza le nto ibe yinto ekhethwayo emikhakheni eminingi efana nemboni yamakhemikhali, ukucubungula ukudla, kanye nobunjiniyela basolwandle.
Ukwakheka kwamakhemikhali kanye ne-microstructure
Ukwakheka kwamakhemikhali kwe-AISI 316L yensimbi engagqwali kulawulwa kahle ukuze kuqinisekiswe izakhiwo zayo ezinhle kakhulu zomzimba namakhemikhali. Okuqukethwe kwekhabhoni ephansi (≤0.03%) kugwema ngempumelelo inkinga ye-intergranular corrosion ngesikhathi sokushisela futhi kuthuthukisa ukumelana nokugqwala okuphelele kwezinto. Okuqukethwe okuphezulu kwe-chromium (16.5% -18.5%) ne-nickel (12% -15%) kunikeza impahla ukumelana ne-oxidation nokuqina, kuyilapho okuqukethwe kwe-molybdenum okungu-2% -3% kuthuthukisa kakhulu ukumelana nokugqwala endaweni ye-chloride. Ngaphezu kwalokho, inani elifanele le-nitrogen (≤0.10%) lithuthukisa amandla nobulukhuni bento ngaphandle kokudela ukuqina kwayo. Le nhlanganisela yokwakheka kwamakhemikhali ethuthukisiwe, ehlanganiswe nesakhiwo esincane esihle nesifanayo esakhiwe ngesikhathi senqubo yokutshala imali, yenza i-gearbox engu-316L yezindlu igcine uzinzo nokuqina okuhle kakhulu ngaphansi kwezimo eziyinkimbinkimbi zengcindezi.
Izakhiwo zemishini nokusebenza kwamandla
I-AISI 316L ye-stainless steel gearbox housing nayo yenza kahle ngokwezakhiwo zemishini. Amandla ayo aqinile ngokuvamile aphakathi kwe-485-620 MPa, futhi amandla ayo okukhiqiza asebangeni le-170-300 MPa, okusho ukuthi ngisho nangaphansi kwezimo ezicindezelayo zomthwalo, izindlu zingakwazi ukugcina ubuqotho besakhiwo futhi azijwayele ukuguquguquka kwepulasitiki noma ukuphuka. Ngesikhathi esifanayo, ukuphakama okungafika ku-40% kanye nokuqina komthelela omuhle kuqinisekisa ukuphepha nokuthembeka kwezindlu lapho zingaphansi kwemithwalo enomthelela. Ngaphezu kwalokho, i-AISI 316L insimbi engagqwali futhi inokuqina okuhle kakhulu kwezinga lokushisa eliphansi futhi ingagcina izakhiwo ezinzile zemishini endaweni ebanda kakhulu, ebaluleke kakhulu kumishini edinga ukusebenza endaweni epholile noma ejulile yolwandle.

Izibonelo Zohlelo Lokusebenza Nokubaluleka Kwezindlu Ze-Gearbox
Izindlu ze-AISI 316L zensimbi engenasici zidlala indima engenakushintshwa ezindaweni eziningi ezibalulekile.
Embonini ye-petrochemical, njengegobolondo lezingxenye zokudlulisela eziyinhloko, azigcini nje kuphela ukumelana nezinga lokushisa eliphezulu kanye nendawo yokusebenza yokucindezela okukhulu, kodwa futhi zimelana nokuguguleka kwemithombo yezindaba eyonakalisayo ehlukahlukene ukuze kuqinisekiswe ukusebenza okuzinzile nokwethembeka kwesikhathi eside kwemishini.
Ezinkundleni zokuxhumana ezingasogwini, izindlu ze-AISI 316L zensimbi engagqwali seziphenduke izingxenye ezibalulekile zokushayela imishini eyinhloko njengamajeneretha nama-compressor ngenxa yokumelana kwazo okuhle nokugqwala kwamanzi olwandle.
Ngaphezu kwalokho, ekucubunguleni ukudla, izimboni zemithi kanye nezinye, izakhiwo ze-sanitary ze-AISI 316L zensimbi engagqwali zenza kube yinto ekhethwayo yemishini yemishini ehlangana nokudla, iqinisekisa ukuphepha nokuhlanzeka komkhiqizo.
