Ake sikhulume ngokuphonsa kwesihlabathi somfutho ophansi. Ngokuvamile akuqondwa kahle, ngisho nangabantu abathile abahwebayo. Akukhona nje ukusakaza isihlabathi samandla adonsela phansi kodwa nomoya omncane. Umqondo oyinhloko usebenzisa igesi elawulwayo, enengcindezi ephansi—imvamisa umoya owomile noma igesi engasebenzi—ukusunduza insimbi encibilikisiwe inyuke ngeshubhu yesikhuphukeli ibe isikhunta sesihlabathi esisuka ngezansi. Ukucindezela kugcinwa kuze kube yilapho ukubunjwa kuqina. Umbono oyiphutha omkhulu? Ukuthi okwezingxenye ezilula kuphela, ezingabalulekile. Ngikubonile lokho kucabanga kuholela kumaphrojekthi angaphezu kweyodwa ahlulekile.
I-Mechanics nokuthi Ingena kuphi
Ukusetha kubonakala kuqondile: isithando somlilo esivaliwe esibambe inyibiliki, ishubhu yesikhuphukeli esicwiliswa kuso, futhi isikhunta sesihlabathi siboshelwe phezulu. Ufaka mhlawumbe i-0.5 kuya ku-1 ibha yokucindezela. Yilokho kucindezela okumnene okwenza umehluko. Ngokungafani nokufakwa kwe-high-pressure die casting, awuphoqi insimbi ngesivinini esikhulu, okusho ukuthi kunesiphithiphithi esincane, ukubambeka okuncane kwegesi, nobuqotho obungcono be-metallurgical. Ukugcwaliswa okulawulwayo kusuka phansi kuya phezulu kuphinde kukhuthaze ukuqiniswa kokuqondisa kuqonde ekhanda lokuphakelayo, okuyinto enkulu yomsindo.
Pho kukhanya kuphi? Kuhle kakhulu ekugijimeni kwevolumu emaphakathi yezingxenye ezidinga ikhwalithi engcono kunokusakazwa kwesihlabathi esiluhlaza okujwayelekile kodwa ezingathetheleli izindleko zokutshala imali kuyo yonke inqwaba. Cabanga ngezinto ezifana nezindlu ze-aluminium alloy zama-compressor, abakaki abathile bezimoto, noma ama-gearbox casing amakhudlwana. Yileyo ndawo ephakathi. Izinkampani ezifana I-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), namashumi eminyaka abo egobolondweni nasekufakweni kwe-investimenti, bangabheka ukukhishwa kwesihlabathi sokucindezela okuphansi njengenqubo ehambisanayo yezidingo ezithile zamaklayenti lapho ezinye izindlela zabo zingase zeqise noma zingafaneleki kahle kujometri.
Awukwazi ukuvele uphonse noma yimuphi umklamo wengxenye kuwo, noma kunjalo. Idizayini yesistimu yokungena ibalulekile—konke kumayelana nalelo sango elilodwa, elibheke phansi. Uma ingxenye inezingxenye ezincane kakhulu kude nesango, ungase ubhekane nezinkinga zokuqinisa ngaphambi kwesikhathi. Udinga ukuqonda okuqinile kwamagradient ashisayo. Lena akuyona inqubo yokuthela nokuthandaza; kubala, ukulawula, nokuqapha okukodwa.
Ukucatshangelwa Okubalulekile kanye Nama-nuances Okucubungula
Nakuba siyibona kakhulu nge-aluminium ne-magnesium alloys, iyasebenza kwamanye ama-alloys asekelwe ethusi ngisho nama-ayina athile okuphonswa. Ukhiye ukuguquguquka kwensimbi nokuthi isabela kanjani ekugcwalisweni okunensayo, okucindezelwe. Isibonelo, nge-aluminium, uthola izakhiwo ezinhle kakhulu zokusebenza ngoba ukugcwalisa okuthulile kunciphisa ukwakheka kwe-oxide. Kodwa kufanele ucophelele mayelana nokuhlanzeka kwensimbi. Noma iyiphi i-slag noma imfucumfucu esithandweni iqhutshelwa phezulu esikhunjeni. Uhlelo oluhle lokuhlunga kushubhu yesikhuphukeli noma esangweni akuxoxiswana ngalo.
Isihlabathi ngokwaso singenye into eguquguqukayo. Ngokuvamile sikhuluma ngesikhunta sesihlabathi esiboshwe nge-resin-njenge-phenolic urethane noma i-sodium silicate-ukuze kube nokuzinza okungcono kwe-dimensional kanye nokuqeda phezulu. Amandla esikhunta kufanele amelane nokucindezela ngaphandle kokuhlanekezelwa, kodwa futhi adinga ukungeneka okwanele ukuze kuphume umoya. Ibhalansi. Ngikhumbula umsebenzi we-pump volute lapho sasisebenzisa khona isihlabathi se-zircon esibheke umgodi ukuze sibambe ukushaqeka okushisayo futhi sithole indawo ebushelelezi njengokusakazwa kwayo. Yasebenza, kodwa yengeza izindleko. Zonke izinqumo ziwukuhwebelana.
Ukulawula ingcindezi kuwubuciko bangempela. Ijika aligcini ngokuvula nokucisha. Ungase ube nesiteji sokucindezela kancane ukuze uqale insimbi ikhuphukele phezulu kweshubhu ngaphandle kokuchaphaza, isiteji sokugcwalisa esikhulu, isiteji sokucindezela ukuze ukondle ukuncipha, nokubamba. Ukwenza leyo phrofayili ibe yiphutha kusho ukungalungi noma ukuguguleka kwesikhunta. Sifake idatha kukho konke ukudubula—ingcindezi, isikhathi, izinga lokushisa lomlilo—futhi sakuhlobanisa nemiphumela ye-X-ray. Ngokuhamba kwesikhathi, uba nomuzwa ngakho, kodwa idatha iyona evimbela izinsalela ezibizayo.
Izinselelo Zomhlaba Wangempela kanye Nokuxazulula Izinkinga
Nali ikhanda eliphathekayo: ishubhu yesikhuphukeli, noma isiqu. Ihlala kubhavu wensimbi encibilikisiwe, ngakho-ke ihlupheka kakhulu ngamabhayisikili ashisayo kanye nokugqwala. Uma ihluleka, unokuvuza okukhulu. Sazama ngezinto ezihlukene eziphikisayo ze-tube lining. Ezinye zaqhekeka kalula, ezinye zasabela nge-alloy. Ukuthola umphakeli oqonda izidingo ezithile ze-thermal namakhemikhali kwakuyiphrojekthi ngokwayo. Yilezi zingxenye ezisizayo ezingenza noma zephule ukuthembeka kwakho ekukhiqizeni.
Enye inkinga ecashile izinga lokupholisa. Ngenxa yokuthi isikhunta sigcwaliswa emthonjeni wensimbi oshisayo futhi ngaphansi kwengcindezi, isakhiwo sokuqinisa singahluka. Ukuze iklayenti elidinga iphrofayili ethile yobulukhuni engxenyeni yokumiswa kwe-aluminium, bekufanele silungise ukupholisa isikhunta ngokubeka amaphiko okupholisa ngobuchule ejazini lesikhunta futhi silungise isikhathi sokubamba ingcindezi. Kuthathe izikhathi eziningana. Amaqoqo okuqala ambalwa abehlukanise ukushrinkage porosity kumphathi okhulayo owugqinsi. Ukulungiswa kwakungeyona ingcindezi eyengeziwe, kodwa ushintsho ku-mold geometry yendawo ukuze udale indlela engcono yokushisa. Izixazululo zezincwadi zokufundisa ngokuvamile zidinga ukuguqulwa kwenkambu.
Ukukhipha umoya kubalulekile kodwa kunzima. Njengoba insimbi iphakama ukuze igcwalise umgodi, umoya kufanele uphumele phezulu. Izintuba ezinganele noma ezibekwe kabi ziholela ekucindezelekeni emuva, okubangela ukugcwaliswa okungaphelele noma amaphakethe egesi. Ngikhumbula ukulingisa okuhlukahlukene lapho sasilokhu sishaywa khona eduze kwaphezulu. Sengeze izimbotshana ezengeziwe, kodwa inkinga yaqhubeka. Kuvele ukuthi iziteshi zokungenisa umoya bezizincane kakhulu futhi bezivinjwa uhlaka olujiyile olusuka kusibophezelo sesihlabathi. Ukuwakhulisa nokuqinisekisa ukuthi indlela eqondile nevulekile iyakuxazulula. Kuhlala kuyizinto ezilula ongazinaki.
Ukuhwebelana Kwezomnotho Nezicelo
