Ubuchwepheshe bokukhiqiza be-cast iron pipe fittings-sand casting
1.Isihlabathi ukusakaza isingeniso.
I-sand casting isetshenziselwa ukwenza izingxenye ezinkulu. Insimbi encibilikisiwe ithululelwa emgodini wesikhunta owenziwe ngesihlabathi. Umgodi esihlabathini wakhiwe ngokusebenzisa iphethini, ngokuvamile eyenziwa ngokhuni, ngezinye izikhathi insimbi. Umgodi uqukethwe ku-aggregate egcinwe ebhokisini elibizwa ngokuthi i-flask. I-Core iwumumo wesanti oshuthekwa esikhunjeni ukukhiqiza izici zangaphakathi zengxenye njengezimbobo noma amaphaseji angaphakathi. Ama-cores afakwa emgodini ukuze enze izimbobo zamajamo afunwayo.
2. Inqubo yokubumba yokubunjwa kwesihlabathi:
Esibunjeni esinezingxenye ezimbili, okuyisimo esivamile sokubunjwa kwesihlabathi, ingxenye engaphezulu, ehlanganisa ingxenye engaphezulu yephethini, i-flask, ne-core ibizwa ngokuthi i-cope kanti ingxenye engezansi ibizwa ngokuthi ukudonsa. Ulayini wokuhlukanisa noma indawo ehlukanisayo ingumugqa noma indawo ehlukanisa i-cope kanye nokudonsa. Ukudonsa kuqala kugcwalisa ingxenye yesihlabathi, futhi ukuphrinta okuphakathi, ama-cores, kanye nesistimu yokufaka isango kubekwa eduze komugqa wokuhlukanisa. Khona-ke i-cope ihlanganiswa emthini, futhi isihlabathi sithululelwa engxenyeni ye-cope, ehlanganisa iphethini, umgogodla kanye nesistimu yokugaya. Isihlabathi sihlanganiswe ukudlidliza kanye nezindlela zemishini. Okulandelayo, i-cope iyasuswa emthini, futhi iphethini isuswe ngokucophelela. Inhloso ukususa iphethini ngaphandle kokuphula umgodi wokubumba. Lokhu kwenziwa lula ngokuklama okusalungiswa, i-angular offset encane ukusuka endaweni eqondile ukuya endaweni eqondile yephethini.
3. Izinzuzo zokufakwa kwamapayipi ensimbi esebenzisa isihlabathi esiluhlaza sobumba
Isihlabathi esiluhlaza sobumba: isihlabathi esinobumba kanye nenani elifanele lamanzi i-Binder eyinhloko, eyenziwe ngokuqondile ngemva kwesikhunta sesihlabathi futhi ithela emanzini. Ukubunjwa kwesihlabathi esiluhlaza kunomlando omude futhi kusetshenziswa kabanzi. Izinzuzo zayo yilezi:
- Impahla eluhlaza iyimithombo eshibhile futhi inala.
- Imodeli yesihlabathi ngaphandle kokumiswa, umjikelezo omfushane wokukhiqiza we-castig nokusebenza kahle okuphezulu, ngakho-ke kulula ukufeza ukukhiqizwa ngobuningi.
- Esihlabathini esidala, i-bentonite enganwetshiwe exutshwe namanzi iyakwazi ukubuyisela amandla, ukugaywa kabusha kwesihlabathi esidala nokusetshenziswa kabusha kokutshalwa kwezimali okuphansi.
- Ngemuva kokusetshenziswa isikhathi eside, senze uhla lwemishini yokubumba.
- Ukunemba kwe-Dimensional of castings okukhiqizwa isihlabathi esiluhlaza sobumba kuqhathaniswa nokufakwa kwe-investimenti.
Ngenxa yalezi zinzuzo, inqubo yesihlabathi sobumba obuluhlaza ekubunjweni okuncane, ikakhulukazi izimoto, izinjini, ama-looms kanye nokunye ukukhiqizwa kwezingxenye zensimbi ezisansimbi sekusetshenziswe kabanzi, ingxenye yamazinga ayo kuqala ekubunjweni. Kodwa-ke, lapho kukhishwa isihlabathi sobumba obuluhlaza, ukuhwamuka kwamanzi esihlabathini kanye nokuthutha, okwenza ukubunjwa kuthambekele ekubeni ne-blowhole, isihlabathi, imbobo yesihlabathi, ukuvuvukala, isihlabathi esinamathelayo nokunye ukukhubazeka.
