Ekwakhiweni kweplathifomu entantayo yomoya oqinile oqondile, ukukhetha kwesisekelo kudlala indima ebalulekile ekusebenzeni kukonke kweplathifomu. Isisekelo se-Granite sokunemba kanye nesisekelo se-iron cast zinezici zazo, futhi kukhona umehluko osobala ebukhulu obubalulekile njengokuzinza, ukugcinwa kokunemba, ukuqina kanye nezindleko.
Okokuqala, ukuzinza: ukuqina kwemvelo kanye nesakhiwo sensimbi
Ngemuva kwezigidi zeminyaka yezinguquko ze-geological, i-granite ihlanganiswe eduze ne-quartz, i-feldspar namanye amaminerali ukuze kwakhe isakhiwo esiminyene kakhulu nesifanayo. Lapho kubhekene nokuphazamiseka kwangaphandle, njengokudlidliza okuqinile okukhiqizwa ukusebenza kwemishini emikhulu endaweni yokusebenzela yasefekthri, isisekelo segwadle singavimba ngokuphumelelayo futhi sinciphise ngokuthembela esakhiweni saso sekristalu esiyinkimbinkimbi, esinganciphisa i-vibration amplitude yesikhulumi somoya esinembayo esintantayo ngaphezu kuka-80%, sinikeze ukusebenza okuzinzile kwetshe legumbi elibushelelezi ngesikhathi sokuthola ukunyakaza okunembayo ukuze kutholakale ukunemba kokunyakaza kwendawo yesikhulumi. Isibonelo, kwinqubo ye-photolithography yokukhiqiza ama-chip kagesi, ukucaciswa okunembile kwamaphethini we-chip kuqinisekisiwe.
Isisekelo sensimbi esisansimbi senziwa nge-iron-carbon alloy, futhi igraphite yangaphakathi isakazwa ngamashidi noma imbulunga. Nakuba inekhono elithile lokudambisa ukudlidliza, ukufana kwayo kwesakhiwo akukuhle uma kuqhathaniswa negwadle. Uma ubhekene nokuqina okuphezulu nokudlidliza okuqhubekayo, kunzima ngesisekelo sensimbi ecijile ukunciphisa ukuphazamiseka kokudlidliza kuye ezingeni eliphansi elifanayo njengesisekelo segwadle, okungase kuholele ekuphambukeni okuncane ekuhambeni kweplathifomu entantayo yomoya oqinile oqondile, okuthinta ukusebenza ngokunemba kweplathifomu ekusebenzeni okunembe kakhulu.
Okwesibili, ukugcinwa kokunemba: izinzuzo zemvelo zokunwetshwa okuphansi kanye nenselelo yoshintsho olushisayo lwensimbi.
I-Granite yaziwa nge-coefficient yayo ephansi kakhulu yokwandisa ukushisa, ngokuvamile ku-5-7 × 10⁻⁶/℃. Esimweni sokushintshashintsha kwezinga lokushisa, usayizi wesisekelo sokunemba se-granite ushintsha kancane kakhulu. Emkhakheni wesayensi yezinkanyezi, inkundla yokuntanta yomoya ye-hydrostatic enembayo yokulungisa kahle ilensi yesibonakude ibhangqwe nesisekelo segwadle, noma ngabe umehluko wezinga lokushisa phakathi kwemini nobusuku ubalulekile, ingaqinisekisa ukuthi ukunemba kokuma kwelensi kugcinwa kuzinga le-submicron, kusize izazi zezinkanyezi ukuthi zithwebule amandla acashile emizimbeni ekude.
I-coefficient yokunwetshwa okushisayo kwensimbi ekhonjiwe iphakeme kakhulu, ngokuvamile i-10-20 × 10⁻⁶/℃. Lapho izinga lokushisa lishintsha, ubukhulu besisekelo se-cast iron buyashintsha ngokusobala, okulula ukubangela ukuguquguquka okushisayo kwesiteji esinembayo sokucindezela komoya esintantayo, okuholela ekwehleni kokunemba kokunyakaza kwesikhulumi. Enqubweni yokugaya yamalensi okukhanya azwelayo kukushisa, ukuwohloka kwesisekelo sensimbi ekhonjiwe ngaphansi kwethonya lokushisa kungase kubangele ukuphambuka kokunemba kokugaya kwelensi ngaphezu kobubanzi obuvunyelwe futhi kuthinte ikhwalithi yelensi.
Okwesithathu, ukuqina: ubulukhuni obukhulu betshe lemvelo nokukhathala kwensimbi
Ukuqina kwe-Granite kuphezulu, ubulukhuni be-Mohs bungafinyelela ku-6-7, ukumelana okuhle kokugqoka. Elabhorethri yesayensi yezinto ezibonakalayo, iplatifomu yokuntanta yokunemba kwe-static air evame ukusetshenziswa, isisekelo sayo segwadle singamelana ngokuphumelelayo nokulahlekelwa ukungqubuzana kwesikhathi eside, uma kuqhathaniswa nesisekelo esivamile, singanweba umjikelezo wokunakekela weplathifomu ngaphezu kuka-50%, sinciphise izindleko zokugcinwa kwemishini, futhi siqinisekise ukuqhubeka komsebenzi wocwaningo lwesayensi. Kodwa-ke, i-granite iqinile, futhi kunengozi yokuphuka uma ithinteke ngengozi.
I-cast iron base inokuqina okuthile futhi akulula ukuphuka lapho ithwala amandla athile omthelela. Kodwa-ke, enkambweni yokunyakaza okuphindaphindiwe okuphindaphindiwe kokunemba kwe-static ingcindezi yomoya yesikhulumi esintantayo isikhathi eside, insimbi ekhonjiwe ijwayele ukulimala kokukhathala, okuholela ekushintsheni kwesakhiwo sangaphakathi, okuthinta ukunemba kokunyakaza nokuzinza kwesikhulumi. Ngesikhathi esifanayo, i-cast iron ijwayele ukugqwala nokugqwala ezindaweni ezinomswakama, inciphisa ukuqina kwayo, ngokuphambene, isisekelo se-granite ekumelaneni nokugqwala singcono.
Okwesine, izindleko zokukhiqiza kanye nobunzima bokucubungula: izimayini zamatshe emvelo nezinselele zokucubungula kanye nomkhawulo wenqubo yokukhipha insimbi
Ukumbiwa kanye nokuthuthwa kwezinto zokusetshenziswa kwe-granite kuyinkimbinkimbi, futhi ukucubungula kudinga imishini nobuchwepheshe obuphezulu kakhulu. Ngenxa yokuqina kwayo okuphezulu, ukuqina, ukusika, ukugaya, ukupholisha nezinye izinqubo zivame ukuwa, ukuqhekeka, izinga eliphezulu le-scrap, okuholela ezindlekweni eziphezulu zokukhiqiza.
Isisekelo sensimbi esakhiwe sakhiwe ngenqubo yokuphonsa evuthiwe, umthombo obanzi wezinto ezingavuthiwe kanye nezindleko eziphansi uma kuqhathaniswa. Ngokusebenzisa isikhunta kungaba kuzuzwe ukukhiqizwa mass, high ukukhiqiza ukusebenza kahle. Kodwa-ke, ukuze kuzuzwe ukunemba okuphezulu okufanayo nokuzinza njengesisekelo se-granite, inqubo yokuphonsa kanye nezidingo zangemuva kokucubungula ziqinile kakhulu, ezidinga ukunemba kwemishini nokwelashwa kokuguga, njll., futhi izindleko nazo zizokhuphuka kakhulu.
Kafushane, isisekelo se-granite esinembayo sinezinzuzo eziphawulekayo ezimweni zokusetshenziswa kweplatifomu yokuntanta yomoya oqinile we-static edinga ukunemba okuphezulu, ukuzinza nokumelana nokugqoka; Isisekelo se-cast iron sinezinzuzo ezithile ezindlekweni nasekuqineni, futhi sifanele izikhathi lapho izimfuneko zokunemba ziphansi ngokuqhathaniswa, ukuphishekela ukuphumelela kwezindleko kanye nendawo yokudlidliza nezinga lokushisa kuzinzile uma kuqhathaniswa.
