Emkhakheni wokulinganisa ukunemba, ukuzinza kwesisekelo sempahla yokulinganisa kunquma ngokuqondile ukuthembeka kwedatha. Inkinga yephutha lokulinganisa elibangelwa ukuwohloka kokushisa kwezisekelo zensimbi kudala ihlupha imboni yokukhiqiza. Nokho, inkundla yensimbi yokulinganisa ukucaba kwegwadle eyethulwe i-ZHHIMG, nesitifiketi sayo sokunemba kwezinga le-AAA esephula izindinganiso zomkhakha, ihlinzeka ngesixazululo esiguquguqukayo sokulinganisa okunembayo okuphezulu.
Inkinga yokuguquka kwe-thermal yezisekelo zensimbi: Umbulali Ongabonakali wamaphutha okulinganisa
Izisekelo ze-cast iron zake zasetshenziswa kabanzi ekulinganiseni impahla ngenxa yezindleko eziphansi kanye nokuqina okuqinile. Kodwa-ke, ekusetshenzisweni okungokoqobo, ukuhlehliswa kokuzinza kwabo okushisayo kwe-thermal kuye kwavela kancane kancane. I-coefficient yokunwetshwa okushisayo kwensimbi ekhonjiwe iphezulu njengokungu-11-12 ×10⁻⁶/℃. Uma okokusebenza kusebenza noma izinga lokushisa le-ambient lishintshashintsha, lithambekele kakhulu ekuwohlokeni kokushisa. Isibonelo, lapho izinga lokushisa le-ambient endaweni yokusebenzela lishintsha ngo-5℃, isisekelo se-cast iron singase sishintsheke ngomugqa ongu-0.0055-0.006mm. Ushintsho olunjalo oluncane luzobangela ngokuqondile ukuthi inkomba yokulinganisa ishintshe, iphindaphinde iphutha lokulinganisa.
Ngaphezu kwalokho, ukuqhutshwa kokushisa kwesisekelo se-cast iron akulingani. Lapho okokusebenza kusebenza, ukushisisa kwendawo kuzodala "umphumela we-thermal gradient", okuholela ekuhlanekezeleni nasekuguquguqukeni ebusweni besisekelo. Esilinganisweni sokucaba, lokhu kuguqulwa kungabangela ukuchezuka endaweni ehlobene phakathi kwe-probe yokulinganisa nento elinganiswayo, ekugcineni kukhiphe idatha yokulinganisa engalungile. Ngokwezibalo zemboni, imishini yokulinganisa ngezisekelo zensimbi, amaphutha abangelwa ukuwohloka kwe-thermal akhawunti angaphezu kuka-40% wamaphutha aphelele, okuthinta kakhulu ukunemba kokuhlolwa kwekhwalithi yomkhiqizo.
Ukuphumelela kwezobuchwepheshe kweplatifomu ye-granite ye-ZHHIMG: Ukuqeda ukuwohloka okushisayo kusuka empandeni
I-ZHHIMG granite yesikhulumi sensimbi yokulinganisa flatness ithatha igwadule yemvelo njengento eyisisekelo, ixazulula inkinga yokuguquka okushisayo kusukela engqikithini yento. I-coefficient yokunwetshwa okushisayo kwe-granite ingu-5-7 × 10⁻⁶/℃ kuphela, okuyingxenye kuphela yensimbi ekhonjiwe. Ngaphezu kwalokho, isakhiwo sayo sangaphakathi siminyene futhi sifana. Ngisho nangaphansi kokushintsha kwezinga lokushisa okwedlulele, ingagcina usayizi ozinzile nokuma. Idatha yaselabhorethri ibonisa ukuthi endaweni enokushintshashintsha kwezinga lokushisa okungu-20℃, ukuwohloka komugqa weplatifomu yegwadle kungaphansi kuka-0.0014mm, okucishe kungabi nandaba.
Ngaphezu kwezinzuzo zezinto ezibonakalayo, i-ZHHIMG isebenzisa ubuchwepheshe obunelungelo lobunikazi bokucubungula ukunemba okuphezulu. Ngokusebenzisa amasu e-CNC okugaya nokupholisha, ukucaba kwendawo yesikhulumi kuyathuthukiswa kufinyelele ku-±0.001mm/m, kufinyelele ezingeni eliphezulu embonini. Phakathi naleso sikhathi, isakhiwo sokukhulula ukucindezeleka okumise okwekhekheba lezinyosi siklanyelwe ngaphakathi kweplatifomu, okuqhubeka kuthuthukisa ukuqina ngenkathi kuhlakaza ngokuphumelelayo ukuguqulwa kwamaminithi okubangelwa ukucindezeleka okushisayo, ukuqinisekisa ukuthi isithenjwa sokulinganisa sihlala sizinzile futhi sithembekile ngaso sonke isikhathi.
Isitifiketi sokunemba kwezinga le-Aaa: Ukuzinikela kwekhwalithi okusekelwa igunya
Inkundla yegwadle ye-ZHHIMG iphase isitifiketi sokunemba sezinga le-AAA yisikhungo esigunyaziwe samazwe ngamazwe. Leli zinga lokunikeza isitifiketi lidinga ukuthi iphutha lesilinganiso lesisetshenziswa lihlale lilawulwa ngaphakathi kuka-±0.3μm ngaphansi kwezinguquko eziningi zemvelo ezifana nezinga lokushisa, umswakama nokudlidliza. Ukuze kuhlangatshezwane naleli zinga, i-ZHHIMG isungule uhlelo oluphelele lokulawula ikhwalithi: kusukela ekuhlolweni kwe-granite ore eluhlaza, ukucubungula ngokunemba kuya ekuhlolweni kwemikhiqizo eqediwe, isixhumanisi ngasinye sigadwa ngokuqinile ngemishini yokuhlola ezenzakalelayo. Isibonelo, i-laser interferometer isetshenziswa ukwenza ukuskena kwezinga le-micron yendawo yesikhulumi ukuze kuqinisekiswe ukuthi iphutha lokucaba liyathuthukiswa. Ukuzinza okushisayo kweplathifomu kuqinisekiswa ngokulingisa izindawo ezeqisayo kusetshenziswa ilabhorethri engapheli yokushisa nomswakama.
Kuzinhlelo zokusebenza ezingokoqobo, inkundla ye-ZHHIMG ibonise izinzuzo ezibalulekile ezimbonini ezifana nama-semiconductors, ama-optical lens, kanye nokubunjwa okunembayo. Ngemuva kokuthi inkampani ethile ye-semiconductor yethule le nkundla, iphutha lokulinganisa ukucaba kwehliswe ngo-90%, futhi izinga lokukhiqiza umkhiqizo lenyuke ngo-15%, ukuxazulula ngempumelelo inkinga yokuphinda isebenze edalwe amaphutha okulinganisa.
Ngokumelene nokwasemuva kokuthuthukela kwemboni yokukhiqiza ukuya ekunembeni okuphezulu nobuhlakani, inkundla yethuluzi lokulinganisa ukugcwala kwegwadle le-ZHHIMG ichaze kabusha izinga lokulinganisa ngokunemba ngokulawula kwayo kokugcina ukuwohloka kokushisa kanye nesitifiketi sokunemba kwezinga le-AAA. Ayihlinzeki nje kuphela ngeziqinisekiso zokulinganisa ezinokwethenjelwa ezinkampanini, kodwa futhi ikhuthaza ukweqa kobuchwepheshe bemboni kusukela "ekuhluleleni okunamandla" kuya "kukuthola okunembile".
