1- Yintoni ukulahlwa komshini?
Umshini Ivoti, yaziwa ngokuba Negative Pressure Utywiniweyo, Ukuncitshiswa Pressure Ivoti okanye V Inkqubo eyahlulayo. Umshini wokuphosa uxinzelelo olubi lolunye uhlobo lokuphosa isanti eyomileyo kwaye ifuna ukusetyenziswa kwesixhobo sokukhupha umoya ukukhupha umoya ngaphakathi ekubunjweni komngundo, emva koko usebenzise umahluko woxinzelelo phakathi ngaphakathi nangaphandle kwesikhunta ukugubungela ifilimu yeplastiki eshushu iipateni kunye neetemplate. Ubunjani bokuphosa buya komelela ngokwaneleyo ukuba bumelane nesinyithi esityhidiweyo ngexesha lokuphosa. Emva kokufumana umngundo wokuphosa, gcwalisa ibhokisi yesanti ngesanti eyomileyo ngaphandle kwesibophelelo, emva koko utywine umphezulu womngundo wesanti ngefilimu yeplastiki, ulandelwe ngumoya wokwenza isanti yomelele kwaye iqine. Emva koko, susa ukungunda, ubeke isanti cores, uvale ukungunda ukwenza nantoni na ekulungele ukugalela. Okokugqibela, ukulahlwa kufunyenwe emva kokuba isinyithi esityhidiweyo sipholile kwaye siqinisiwe.
2- Zeziphi iingenelo zokuphosa uMshini?
1) I-castings ye-vacuum inokuchaneka okuphezulu, ulwandiso olucacileyo kunye nomphezulu ogudileyo.
2) Akukho zibophelelo, amanzi kunye nezongezo kwisanti yokubumba, eyenza ukulungiswa kwentlabathi kube lula.
3) Kulula ukucoca ii-castings. Iigesi ezinganabungozi ziveliswa ngexesha lenkqubo yokuphosa.
4) Ukufakwa kwe-vacuum kungasetyenziselwa kuluhlu olubanzi lwamashishini. Ingasetyenziselwa imveliso enye yebhetshi encinci kunye nokuveliswa kobunzima, ngakumbi ukubumba okukhulu kunye naphakathi kunye nokujula okubiyelweyo kufanelekile ekuphoseni.
3- Zeziphi izinyithi kunye neeAlloys ezinokuphoswa ngokuTsalwa kweVuvu?
• I-Iron Gray yentsimbi, i-Ductile Cast Iron
• Ikharbon yentsimbi: Ikharbhoni ephantsi, icarbon ephakathi kunye nekhabhoni ephezulu
• Yenza iAlloys zentsimbi: Isinyithi esiphantsi, intsimbi ephezulu, intsimbi ekhethekileyo
• IAluminiyam kunye neealloys zayo
• I-Brass kunye neCopper.
4- Zeziphi iiShishini eziSetyenziselwa iZinto eziCociweyo?
Njengoko kukhankanyiwe apha ngasentla kwiingenelo zokuphosa i-vacuum, i-vacuum castings ingasetyenziselwa kuluhlu olubanzi lwamashishini. Ingasetyenziselwa imveliso enye yebhetshi encinci kunye nokuveliswa kobunzima, ngakumbi ukubumba okukhulu kunye naphakathi kunye nokujula okubiyelweyo kufanelekile ekuphoseni. Ke ngoko, izinto ezincamathelayo zisetyenziselwa oomatshini bezolimo, iinkqubo ze-hydraulic, iimoto zothutho zikaloliwe, iikhreyithi kunye namashishini okwakha iinqanawa.
I-5- Yeyiphi into yokuNyamezelwa koKhuseleko enokuthi ifikelelwe yiNkqubo yoKwenza iCandelo?
Ngexesha lokuphosa, njengoko umphezulu womfuziselo ugqunywe yifilimu yeplastiki, akukho sidingo sokungcangcazela okanye unkqonkqoze xa utsala ukungunda. Ukutsalwa kunye noxinzelelo olubi lwenza ukuba isanti yokubumbana incamathele, kwaye ubunzima bokubumba kwesanti kuphezulu kwaye kufane. Ngaphantsi kobushushu bentsimbi etyhidiweyo, isusu akukho lula ukukhubazeka. Ngaphezu koko, ubukho boxinzelelo olungelulo lubangela ukugcwaliswa ngokupheleleyo kwesinyithi esityhidiweyo kwimodeli. Ubume bomphezulu benkqubo yokuphoswa kwe-V inokufikelela kwiRa = 25 ~ 2.5μm. Inqanaba lokunyamezelana ngokwemeko yokuphosa inokufikelela kwi-CT5 ~ CT7. Umgangatho wokubonakala kokuphoswa koxinzelelo kulungile, kwaye umgangatho wangaphakathi unokuthenjwa.
