Ezimbonini ezinemininingwane ephezulu—kusukela ezindizayo nasezimotweni kuya emandleni nasemishinini esindayo—isidingo sokunemba asinciphi ngoba nje izingxenye ziya zikhula. Ngokuphambene nalokho, izingxenye ezinkulu njengezindlu ze-turbine, ama-gearbox casings, noma ama-weldment esakhiwo ngokuvamile anezimo eziqinile zejometri uma kuqhathaniswa nosayizi wazo, okwenza ukulinganisa okuthembekile kungabi yinselele nje kuphela, kodwa kube yinto ebalulekile emsebenzini. Noma kunjalo, izindawo eziningi azinaki isici esibaluleke kakhulu ekuhlolweni okukhulu: ukuzinza kanye nokuba yisicaba kwendawo ebhekisela kuyo abayisebenzisayo. Uma usebenza ngepuleti elikhulu le-granite surface, usuvele uyaqonda inani layo—kodwa ingabe uthola ukusebenza okugcwele ekwazi ukukunikeza?
Iqiniso liwukuthi,ipuleti le-granitekukodwa akwanele. Ngaphandle kokusekelwa okufanele, ukulawulwa kwemvelo, kanye nokuhlanganiswa komsebenzi we-metrology olinganisiwe, ngisho ne-slab esezingeni eliphezulu ingenza kahle kakhulu—noma okubi nakakhulu, ilethe amaphutha afihliwe. Yingakho abakhiqizi abaphambili bengathengi nje ipuleti; batshala imali ohlelweni oluphelele—ikakhulukazi, ukunembaipuleti lobuso begranitengesitendi esakhelwe ukuqina, ukufinyeleleka, kanye nokuzinza kwesikhathi eside. Ngoba lapho ipuleti lakho liwohloka ngisho nangaphansi kwesisindo salo noma lidlidliza kusuka emishinini eseduze, ukufundwa ngakunye kokuphakama, ukuhlolwa ngakunye kwesikwele, kanye nokulungiswa ngakunye kuyasolisa.
I-Granite ibilokhu iyindinganiso yegolide yezindawo zokubhekisela ngokunemba iminyaka engaphezu kwengu-70, futhi ngesizathu esihle sesayensi. Ukwakheka kwayo okumnyama okunezinhlayiya ezincane, okungenazo izimbobo kunikeza ukuzinza okumangalisayo kobukhulu, ukwanda okuncane kokushisa (ngokuvamile okungu-6–8 µm ngemitha ngayinye ngo-°C), kanye nokuncishiswa kwemvelo kokudlidliza komshini—konke kubalulekile lapho kuqinisekiswa izici ezingxenyeni zamathani amaningi. Ngokungafani namatafula ensimbi ensimbi noma enziwe ngensimbi, aguquguquka ngokushintsha kwezinga lokushisa, agqwale ngokuhamba kwesikhathi, futhi agcine ukucindezeleka kwangaphakathi, i-granite ihlala ingangeni ngaphansi kwezimo ezijwayelekile ze-workshop. Yingakho amazinga omhlaba wonke njenge-ASME B89.3.7 kanye ne-ISO 8512-2 echaza i-granite njengento kuphela eyamukelekayo yamapuleti obuso eBanga 00 kuya kuBanga 1 asetshenziswa ekulinganisweni nasekuhlolweni kokunemba okuphezulu.
Kodwa isikali sishintsha konke. Ipuleti elikhulu le-granite surface—ake sithi, 2000 x 4000 mm noma ngaphezulu—lingasinda ngaphezu kwamakhilogremu angu-2,000. Kulelo sisindo, indlela elisekelwa ngayo iba yinto ebaluleke kakhulu njengezinga lalo lokuba yisicaba. Ukwakheka kokuma okungalungile (isb., ukubekwa kwemilenze okungalingani, ozimele abaguquguqukayo, noma ukusekelwa okunganele) kungabangela ukuphambuka okudlula amabhande okubekezelela avumelekile. Isibonelo, ipuleti le-Grade 0 elilinganisa ama-3000 x 1500 mm kumele ligcine ukuba yisicaba ngaphakathi kwama-±18 microns kulo lonke ubuso balo ngokwe-ISO 8512-2. Uma i-stand ivumela ngisho nokugoba okuncane phakathi nendawo, lokho kuchazwa kwephulwa ngokushesha—hhayi ngenxa ye-granite embi, kodwa ngenxa yobunjiniyela obubi.
Yilapho ingxenye ethi “ne-stand”ipuleti lobuso be-granite elinembilenge-stand ishintsha kusuka ku-accessory ibe yisidingo esiyinhloko. I-stand eyakhelwe injongo akuyona nje uhlaka—yisistimu yesakhiwo eklanyelwe kusetshenziswa ukuhlaziywa kwezinto ezilinganiselwe ukusabalalisa umthwalo ngokulinganayo, ukunciphisa i-resonance, nokunikeza ukwesekwa okuzinzile kwamaphuzu amathathu noma amaningi okuhambisana namaphuzu emvelo e-nodal epuleti. Izitendi eziphezulu zinezinyawo ezilungisekayo, ezihlukanisa ukudlidliza, ukuqinisa okuqinisiwe, kanye nokufinyelela kwe-ergonomic kwabasebenzi nemishini. Ezinye zize zihlanganise izindlela zokumisa ukuze zisakaze i-static—ebalulekile ezindaweni ze-elekthronikhi noma zegumbi lokuhlanza.
Kwa-ZHHIMG, sizibonele mathupha ukuthi uhlelo olufanele lushintsha kanjani imiphumela. Omunye umenzi we-wind turbine waseNyakatho Melika wabhekana nobunzima bokulinganisa i-bore alignment engaguquki ezisekelweni ze-nacelle. Itafula labo le-granite elikhona lalihleli ohlakeni lwensimbi olusetshenziswe kabusha olwalugobeka ngaphansi komthwalo. Ngemva kokufaka ipuleti lobuso le-granite elikhulu eliqinisekisiwe elifakwe esitendini esenziwe ngokwezifiso esinezinyawo zokulinganisa ezilinganisiwe, ukuhlukahluka kwabo kwe-inter-operators kwehle ngo-52%, futhi ukwenqatshwa kwamakhasimende kwaphela ngokuphelele. Amathuluzi ayengashintshile—isisekelo kuphela.
Okubaluleke ngokulinganayo yindlela lezi zinhlelo ezihlangana ngayo emisebenzini yansuku zonke. Ipuleti lobuso le-granite elinokunemba eliklanywe kahle eline-stand liphakamisa indawo yokusebenza ibe ukuphakama okuqondile (ngokuvamile okungu-850–900 mm), kunciphisa ukukhathala komqhubi ngesikhathi sokuhlola isikhathi eside. Linikeza ukufinyelela okucacile kuzo zonke izinhlangothi kwezingalo ze-CMM, ama-laser tracker, noma amathuluzi esandla. Futhi ngenxa yokuthi i-stand ihlukanisa i-granite ekudlidlizeni phansi—okuvamile eduze kokucindezela, imigqa yokunyathela, noma amayunithi e-HVAC—ligcina ubuqotho bezinkomba zokudayela ezibucayi noma ama-masters okuphakama kwe-elekthronikhi.
Ukugcinwa kwayo kudlala indima. Nakuba i-granite ngokwayo idinga ukunakekelwa okuncane ngaphandle kokuhlanzwa njalo nge-isopropyl alcohol, i-stand kumele ihlolwe njalo ukuze kutholakale ukucindezeleka kwe-bolt, ukuhleleka, kanye nobuqotho besakhiwo. Futhi njenge-plate, yonke inhlangano kufanele ihlolwe njalo. Ukulinganiswa kwe-surface plate yangempela yezinhlelo ezinkulu akubandakanyi nje ukumepha kwe-granite okuyisicaba, kodwa nokuhlolwa kokuqina kwesistimu iyonke—kufaka phakathi ukuphambuka okubangelwa ukuma ngaphansi komthwalo olingiswayo.
Uma ukhetha ipuleti elikhulu le-granite surface, bheka ngale kobukhulu kanye nentengo. Cela:
- Isitifiketi esigcwele se-ASME B89.3.7 noma i-ISO 8512-2, kufaka phakathi imephu yesimo sokuphambuka kwangempela kokusicaba
- Imibhalo yemvelaphi ye-granite (eqoqwe kahle, ekhululekile ekucindezelekeni, engenazo izimfa)
- Imidwebo yobunjiniyela yesitendi, ekhombisa i-geometry yokusekela kanye nemininingwane yezinto ezibonakalayo
- Idatha yokuhlaziya ukudlidliza uma isebenza ezindaweni eziguquguqukayo
Kwa-ZHHIMG, sibambisana kuphela nama-workshop aphatha izinhlelo ezinkulu ze-granite njengezingxenyekazi ze-metrology ezihlanganisiwe—hhayi izimpahla. Ipuleti ngalinye le-granite elinembile elinesitendi esilinikezayo lihlolwa ngalinye ngaphansi komthwalo, lihlelwe ngokulandelana ukuze lilandeleke, futhi lihambisana nesitifiketi sokulinganisa esingalandeleka se-NIST. Asikholelwa "ekusondeleni ngokwanele." Ku-metrology enkulu, asikho isikhala sokuyekethisa.
Ngoba uma ingxenye yakho ibiza amanani ayisithupha futhi ikhasimende lakho lifuna ukulethwa okungenasici, indawo yakho yokubhekisela ayikwazi ukuba yinto ecatshangelwe kamuva. Kumelwe kube yimpahla yakho ethembeke kakhulu—isiqinisekisi esithule seqiniso ezweni lapho ama-micron ebaluleke khona.
Ngakho-ke zibuze: ingabe ukusethwa kwakho kwamanje kuyayisekela ngempela imigomo yakho yokunemba—noma kuyayichitha buthule? Kwa-ZHHIMG, sikusiza ukuthi wakhe ukuzethemba kusukela phansi, ngezinhlelo ze-granite eziklanywe ngobunjiniyela ezinikeza ukunemba ongakulinganisa, ukukwethemba, nokuvikela.
