Iindlela ezintathu zokuphosa iMibhobho yentsimbi yokuphosa

Imibhobho yentsimbi eyenziweyo iye yaveliswa ngeendlela ezahlukeneyo zokuphosa ngokuhamba kwexesha. Makhe sihlolisise iindlela ezintathu eziphambili:

1. I-Horizontally Cast: Imibhobho yentsimbi yokuqala yaphoswa ngokuthe tye, kunye nombindi womngundo oxhaswe ziintonga zentsimbi ezincinci eziye zaba yinxalenye yombhobho. Nangona kunjalo, le ndlela ihlala ikhokelela ekuhanjisweni okungalinganiyo kwesinyithi kumjikelezo wombhobho, okukhokelela kumacandelo abuthathaka, ngakumbi kwisithsaba apho i-slag ithande ukuqokelela.
2. Ukusasazwa ngokuthe nkqo: Ngo-1845, utshintsho lwenzeka olubhekiselele ekujuleni ngokuthe nkqo, apho imibhobho yaphoswa emhadini. Ngasekupheleni kwenkulungwane ye-19, le ndlela yaba yinto eqhelekileyo. Ngokuphosa ngokuthe nkqo, i-slag iqokelelwe phezulu kwi-casting, evumela ukususwa ngokulula ngokusika ukuphela kombhobho. Nangona kunjalo, imibhobho eveliswe ngale ndlela ngamanye amaxesha inengxaki yokubhobhoza ngaphandle kombindi ngenxa yombindi wokungunda ubekwe ngendlela engalinganiyo.
3. I-Centrifugally Cast: I-Centrifugal casting, eyasungulwa ngu-Dimitri Sensaud deLavaud ngo-1918, yaguqula ukwenziwa kwemibhobho yentsimbi. Le ndlela ibandakanya ukujikeleza isikhunta ngesantya esiphezulu ngelixa isinyithi esinyibilikisiweyo singeniswa, sivumela ukuhanjiswa kwesinyithi esifanayo. Ngokomlando, iindidi ezimbini zokubumba zazisetyenziswa: i-metal molds kunye ne-sand molds.

• Ukungunda kwesinyithi: Ngale ndlela, intsimbi enyibilikisiweyo yangeniswa kumngundo, eyaphothwayo ukuze isasazwe isinyithi ngokulinganayo. Ukungunda kwesinyithi kwakukhuselwe ngokuhlamba kwamanzi okanye inkqubo yokutshiza. Emva kokupholisa, imibhobho yayitsalwa ukuze kuthomalaliswe uxinezeleko, ihlolwe, igqunywe, ize igcinwe.

• Ukungunda kwesanti: Iindlela ezimbini zisetyenziselwe ukubunjwa kwesanti. Eyokuqala ibandakanyeka ekusebenziseni ipateni yesinyithi kwiflask egcwele isanti yokubumba. Indlela yesibini yasebenzisa i-flask evuthayo efakwe kwi-resin kunye nesanti, ukwenza i-mold centrifugally. Emva kokuqina, imibhobho yayipholiswa, ifakwe emanzini, ihlolwe, ize ilungiselelwe ukusetyenziswa.

Zombini iindlela zokubunjwa kwesinyithi kunye nesanti zilandela imigangatho ebekwe yimibutho efana ne-American Water Works Association kwimibhobho yokuhambisa amanzi.

Isishwankathelo, ngelixa iindlela zokuphosa ezithe tyaba nezithe nkqo zinemida yazo, ukuphosa okuphakathi kube yeyona ndlela ikhethwayo yokuveliswa kwemibhobho yentsimbi yale mihla, iqinisekisa ukufana, amandla, kunye nokuthembeka.
