Uma uzwa 'okuyisisekelo sokubunjwa kwensimbi', izincwadi zokufunda eziningi zigxuma ziqonde kumdwebo wokugeleza: iphethini, isikhunta, thela, pholisa, qeda. Akulungile lokho, kodwa kufana nokuchaza ukushayela ngokubhala izingxenye zemoto. Izinto eziyisisekelo zangempela zihlala ezikhaleni phakathi kwalezo zinyathelo—ukushisa okushisayo phezu kweladi, umsindo wensimbi egcwalisa isikhunta, indlela isikhunta segobolondo esizizwa ngayo lapho silungile. Ngibone onjiniyela abaningi besanda kuphuma esikoleni belungisa imodeli ye-CAD, bakhohlwe ukuthi insimbi inentando yayo. Lowo owokuqala, futhi mhlawumbe omkhulu kakhulu, umbono oyiphutha: ukulingisa akuyona nje inqubo yokukhiqiza; kuwukuxoxisana ne-physics.
Umdanso Omkhulu: Iphethini, Isikhunta, Nensimbi
Ake siqale ngephethini. Yindawo yokuqala, kepha ukwakheka kwayo yilapho uwina khona noma ulahlekelwe umsebenzi. Ama-engeli asalungiswa akusiyo nje inombolo emanuwali; i-half-degree ingasho umehluko phakathi kwe-strip ehlanzekile kanye nesikhunta esicekeleke phansi. Lokhu sikufunde kanzima emsebenzini wakuqala wendlu yephampu, sisebenzisa iphethini yeresin. Idizayini ibibukeka iphelele esikrinini, kodwa asizange sicabangele ukunwetshwa kokushisa kwe-resin ngaphansi kokushisa okukhulu kwe-resin. ukubunjwa kwegobolondo inqubo. Umphumela? Isikhunta esihle esinokunemba kobukhulu obusabekayo. Ingxenye yayiyizicucu. Lokho kwehluleka kwangifundisa okwengeziwe mayelana izinto eziyisisekelo zokubunjwa kwensimbi kunanoma iyiphi incwadi: zonke izinto eziseketango, kusukela kuphethini kuye kweyensimbi yokugcina, ziyakhula kanye nezinkontileka. Kufanele ubazi bonke.
Okungilethela isikhunta. Esitolo sethu, I-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., sincike kakhulu egobolondweni nasekufakweni kwezimali. Ukukhetha akunangqondo. Okwevolumu ephezulu, amajiyometri alula kakhulu ezintweni ezifana insimbi noma i-carbon steel, ukubumba igobolondo kusebenza ngendlela emangalisayo. Isihlabathi se-silica esimbozwe nge-phenolic resin sikunikeza isikhunta esinokuphela okuhle kakhulu nokungena okuhloniphekile. Kodwa iqhinga eliyisisekelo lisekwelapheni. Isikhunta sidinga isikhathi esifanele kuhhavini. Incane kakhulu, futhi ibuthakathaka, ibeka engcupheni yokuphuma ngesikhathi sokuthela. Kuningi kakhulu, futhi kuba brittle, okungase kubangele ukufakwa ekulingiseni. Ufunda ukuyehlulela ngombala nangephunga—iphunga elicacile, elinephunga elimnandi leresin ephulukisiwe. Ayikho kunoma iyiphi imanuwali.
Ukutshala imali, noma i-wax elahlekile, isilwane esihlukile. Okwezinto eziyinkimbinkimbi—izindwani zomoya, imizimba yamavalvu eyinkimbinkimbi. Okubalulekile lapha ukulawula, ukulawula okuphelele, phezu kwazo zonke izingqimba zegobolondo le-ceramic. Ibhamuza elincane noma indawo ebuthakathaka engutsheni yesithathu izovela njengephiko noma ibhamuza engxenyeni yokugcina yensimbi engagqwali. Siyisebenzisela kakhulu umsebenzi wethu ngama-alloys akhethekile, njengalawo asekelwe ku-nickel. Ukumelana nokushaqeka okushisayo kwegobolondo le-ceramic kufanele kufane ngokuphelele nezinga lokushisa lokuthululwa kwalawa ma-superalloys. Yenza iphutha, futhi igobolondo liyaqhekeka, insimbi iyavuza, futhi unesiphithiphithi esibiza kakhulu, esiyingozi. Kuyinqubo esezingeni eliphezulu lapho okuyisisekelo kumayelana nokubekezela nokuphindaphinda okucophelelayo.
The The Pour: Lapho Ithiyori Ihlangana Naphansi
Lesi yisikhathi seqiniso. Konke ukuhlela kuphelela lapha. I izinto eziyisisekelo zokubunjwa kwensimbi ngesikhathi sokuthela kumayelana ne-thermodynamics kanye ne-fluid dynamics, kodwa awuxazululi izibalo; wenza izinqumo phakathi kwesibili. Izinga lokushisa lensimbi libalulekile. Ngensimbi ene-ductile, sihlose cishe u-°C. Kodwa leyo akuyona inombolo engashintshi. Uma isikhunta kubanda futhi siswakama ngosuku oluswakeme, ungase ushise ukuze uvimbele ukubanda ngaphambi kwesikhathi ezingxenyeni ezincane. Ubuka ukugeleza kwensimbi ku-ladle-kufanele kube umfudlana ozinzile, okhanyayo, hhayi i-splatter. Ukuthulula okuneziyaluyalu kwethula umoya nama-oxide, okuholela ekulimaleni.
Ama-Risers nama-gateing systems amaqhawe angaqanjwanga. Akuzona nje iziteshi zensimbi; bawuhlelo lwengcindezi nokudla. Ngikhumbula umsebenzi wegiya eliwugqinsi elingenalutho ngensimbi. Sibeke isikhuphukeli ngokusekelwe ekubaleni okujwayelekile. I-casting yaqina, futhi yayibukeka iphelele. Kuze kusetshenziswe imishini. Imbobo enkulu yokuncipha ibifihlwe khona kanye kuwebhu. Isikhuphukeli sasiqine ngaphambi kwengxenye ewugqinsi, ngakho sasingakwazi ukusondla. Okuyisisekelo esikugejile? Ukwenza imodeli yokuqinisa akukhona nje ngevolumu; kumayelana nendlela nesikhathi. Manje sisebenzisa isofthiwe yokulingisa njengesiqondiso, kodwa sisahlola imithetho emidala yesithupha—njengokuqinisekisa ukuthi isisindo sokushisa sesikhuphukeli sikhulu kakhulu kunesigaba esisinikezayo.
Material Uyikho Konke (Futhi Akukho)
Abantu bavame ukucabanga ukuthi ukukhetha impahla kuyisinyathelo sokuqala. Kwesinye isikhathi kuba njalo, kepha imvamisa, ukwakheka kuyakuyalela, futhi kufanele ukwenze kusebenze. Siphatha yonke into ngokujwayelekile insimbi kuma-alloys asuselwa ku-cobalt exotic. Okubalulekile ngezinto zokwakha ukuqonda ubuntu babo. Insimbi empunga ithulula kahle, iyathethelela emshinini, kodwa izonda umthelela. I-iron Ductile, ne-nodular graphite yayo, iqinile kodwa ijwayele ukuba nezinkinga zokushwabana uma ingelashwanga kahle khona kanye kuladle.
Izinsimbi ezingagqwali, njengo-304 noma 316, ziyinselele ngenxa yendawo yazo ephezulu yokuncibilika kanye nokuthambekela kokwenza izigaba eziqinile, eziphukayo uma izinga lokupholisa lingalawulwa. Futhi ama-alloys akhethekile? Lowo umsebenzi wezinga eliphezulu. Ukuthela ingxubevange esekelwe ku-nickel ekusetshenzisweni kwezinga lokushisa eliphezulu kusho ukulawula yonke into kusukela kumoya wesithando somlilo (ukuvimbela ukukhishwa kwe-oxidation yezinto ezibizayo njenge-chromium) ukuklama isango ukuze kuncishiswe isiphithiphithi esingacekela phansi isikhunta seceramic futhi sonakalise ukuncibilika. Okubalulekile lapha inhlonipho. Awuvele uthele lezi; uhlela wonke umlando wabo oshisayo.
Ngalé Kokusakaza: Ukuxhawulana Kwezandla
Ukulingisa akuvamile ukuba yingxenye eqediwe. Lapha yilapho synergy endaweni efana QSY ibonisa ukubaluleka kwayo. Ukuba CNC imishini endlini akuyona nje into elula; iyiluphu yempendulo eyisisekelo. Ochwepheshe bemishini basitshela kahle lapho ukulingisa kuqinile noma kuthambile, lapho kunokuqina okungalindelekile, noma uma ukubekezelela kwethu kwe-dimensional kumile. Sakhe ubakaki kanye lapho sashiya khona lokho esasicabanga ukuthi kwakuyisitokwe semishini esanele. Ithimba le-CNC labuya lathi ukulingisa bekuhlanekezela ngaphansi kwamandla okusika endaweni eyodwa. Inkinga? Ingcindezi eyinsalela evela ekupholiseni okungalingani. Silungise iphrothokholi yokupholisa endaweni ye-shakeout, inkinga ixazululiwe. Isifundo esibalulekile: ukulingisa akugcini ekunyakazeni. Ukusikwa kokuqala kwethuluzi lomshini wukuhlolwa kwekhwalithi ephezulu.
Lokhu kuhlanganiswa kubumba indlela esiwaklama ngayo amaphethini nezibunzi. Siyazi ukuthi yini imishini yethu engakwazi ukuyenza futhi engakwazi ukuyenza, ngakho-ke siklama ukulingisa ngomshini obhakwe kusukela ekuqaleni. Singase sengeze i-datum pad endaweni engabalulekile ukuze nje sinikeze i-CNC iphuzu elinguziro elithembekile. Lokho kuyisisekelo esisebenzayo osifunda kuphela ngokwenza izinhlangothi zombili zomsebenzi.
Ukwehluleka Izincwadi Zokufunda Zangempela
Ake ngiphethe ngendaba ehlanganisa iqiniso elingcolile, elingelona umugqa izinto eziyisisekelo zokubunjwa kwensimbi. Sibe ne-oda lochungechunge lwama-impellers amelana nokugqwala ensimbi engagqwali eyi-duplex. I-geometry yayiyinkimbinkimbi, i-vanes emincane, ngakho-ke sahamba nokufaka utshalomali. Abambalwa bokuqala baphuma nezinto ezibukeka njengezinyembezi ezincane ebusweni be-vane. Hhayi imifantu, kodwa ukungalungi kwendawo. Sihlole yonke into: imingcele yomjovo we-wax, i-ceramic slurry viscosity, umjikelezo we-autoclave okhishwa ngewaxi. Konke kwakungaphakathi kokucaciswa.
Impumelelo yeza lapho umsunguli omdala, owayebukele buthule, ekhomba i-autoclave yesitimu ephuma incosa. Ubilisa ingcina ngokushesha okukhulu, esho. Isitimu sishaya igobolondo elibandayo, siyajiya, futhi amanzi ayavaleleka ezingxenyeni ezingezansi zesikhunta ngaphambi kokuba aphume. Lapho uthela insimbi encibilikisiwe, lawo manzi akhanya abe nesimusi ngaso leso sikhathi futhi aqhumise imbobo encane ebusweni bobumba, bese insimbi igcwale. Bekuyisisekelo mayelana noshintsho lwesigaba kanye nokufinqa, hhayi mayelana nokusakazwa ngeseshini ngayinye. Sehlisa isivinini sokukhuphuka kwesitimu, savumela ukugeleza kwamanzi okungcono, futhi amaphutha ashabalala. Isisekelo sangempela sasingekho ensimbi; kwakusemanzini. Futhi ngeke ukuthole lokho ngaphandle uma uke wema phansi, wagajwa, ubuka umugqa wezingxenye ezinhle, ezinesici. Inhliziyo yakho konke lokho.
