1- Kuyini Ukuphonsa Umshini?
Umshini Ukulingisa yaziwa nangokuthi Negative Ingcindezi Ekubunjweni, Ukunciphisa Ingcindezi Ekubunjweni noma V Inqubo Ekubunjweni. Umshini omubi wokuphonsa uhlobo oluthile lokuphonsa isihlabathi esomile futhi kudinga ukusetshenziswa kwemishini yokukhipha umoya ukukhipha umoya ngaphakathi kwesikhunta sokukhipha, bese usebenzisa umehluko wengcindezi phakathi kwangaphakathi nangaphandle kwesikhunta ukumboza ifilimu lepulasitiki elishisayo amaphethini nezifanekiso. Isikhunta sokusakaza sizoqina ngokwanele ukumelana nensimbi encibilikisiwe ngenkathi isakazwa. Ngemuva kokuthola isikhunta sokuphonsa umshini, gcwalisa ibhokisi lesihlabathi ngesihlabathi esomile ngaphandle kwesibopho, bese uqinisa ingaphezulu lesikhunta sesihlabathi ngefilimu epulasitiki, kulandelwe i-vacuum yokwenza isihlabathi siqine futhi siqine. Ngemuva kwalokho, susa isikhunta, faka izinhlamvu zesihlabathi, uvale isikhunta ukwenza konke okulungele ukuthululwa. Ekugcineni, ukusakazwa kutholakala ngemuva kokuthi insimbi encibilikile isipholile futhi yaqina.
2- Yiziphi Izinzuzo Zokukhipha Umshini?
1) Ukufakwa kwe-vacuum kunokunemba okuphezulu, uhlaka olucacile nobuso obushelelezi.
2) Azikho izibopho, amanzi nezithasiselo esihlabathini sokubumba, okwenza ukucubungula kwesihlabathi kube lula.
3) Kulula ukuhlanza ukusakazwa komshini. Kukhiqizwa amagesi amancane ayingozi ngesikhathi senqubo yokusakaza.
I-4) Ukufakwa komshini kungasetshenziswa ezimbonini eziningi. Ingasetshenziselwa ukukhiqizwa okukodwa kwe-batch encane kanye nokukhiqizwa kwensimbi, ikakhulukazi ukusakazwa okukhulu nokulingene kanye nokusakazwa okubiyelwe okuncane kufaneleke kakhulu ekubunjweni komshini.
3- Yiziphi Izinsimbi Nama-Alloys Okungasakazwa Ngokukhipha Umshini?
• I-Gray Cast Iron, i-Ductile Cast Iron
• I-Carbon Steel: I-carbon ephansi, i-carbon ephakathi nensimbi ephezulu yekhabhoni
• Ama-Alloys Wensimbi Wensimbi: Insimbi yengxubevange ephansi, insimbi ephezulu yengxubevange, insimbi ekhethekile yengxubevange
• I-Aluminium kanye nama-alloys ayo
• Ithusi Nethusi.
4- Yiziphi Izimboni Ezisetshenziselwe Ukuvota Umshini?
Njengoba kushiwo ngenhla kuzinzuzo zokukhipha umshini, ukusakazwa komshini kungasetshenziswa ezimbonini eziningi. Ingasetshenziselwa ukukhiqizwa okukodwa kwe-batch encane kanye nokukhiqizwa kwensimbi, ikakhulukazi ukusakazwa okukhulu nokulingene kanye nokusakazwa okubiyelwe okuncane kufaneleke kakhulu ekubunjweni komshini. Ngakho-ke, ukukhishwa kwe-vacuum kusetshenziselwa kakhulu imishini yezolimo, amasistimu wokubacindezela, izimoto zezitimela, ama-cranes nezimboni zokwakha imikhumbi.
5- Yikuphi Ukubekezelelana Ekuphoseni Okungahle Kufinyelelwe Ngenqubo Yokuphonsa Umshini?
Ngesikhathi sokuphonsa umshini, ngoba indawo yemodeli imbozwe ifilimu lepulasitiki, asikho isidingo sokudlidliza noma ukungqongqoza lapho udonsa isikhunta. Ukudonsa nokucindezela okungalungile kwenza isihlabathi sokubumba sihlangane, futhi ubulukhuni besikhunta sesihlabathi buphezulu futhi bufana. Ngaphansi kokushisa kwensimbi encibilikisiwe, umgodi akulula ukukhubazeka. Ngaphezu kwalokho, ukuba khona kwengcindezi engemihle kusiza ekugcwalisweni okugcwele kwensimbi encibilikisiwe kwimodeli. Ubulukhuni bendawo yokuphonswa kwenqubo ye-V bungafinyelela eRa = 25 ~ 2.5μm. Izinga lokubekezelelana lobukhulu bokuphonswa lingafinyelela ku-CT5 ~ CT7. Ikhwalithi yokubukeka kokuphonswa kwengcindezi engemihle muhle, futhi ikhwalithi yangaphakathi inokwethenjelwa.
