1- Chii Chinonzi Vacuum Kukanda?
Vacuum Kukanda kunozivikanwa seNegative Pressure Yakavharwa Kukanda, Yakaderedzwa Pressure Kukanda kana V Maitiro Ekukanda. Vacuum yakaipa kumanikidza kukanda ndeimwe mhando yeakaoma jecha kukanda uye inoda kushandiswa kwemhepo kuburitsa michina kuburitsa mweya mukati mekukanda chakuvhuvhu, uye wozoshandisa kumanikidza mutsauko pakati pekunze nekunze kweforoma kuvhara iyo inopisa ipurasitiki firimu pane mapatani uye matemplate. Iyo yekukanda muforoma inozove yakasimba zvakakwana kuti itsungirire iyo yakaumbwa simbi panguva yekukanda. Mushure mekuwana iyo yekutsiva yekukanda muforoma, zadza bhokisi rejecha nejecha rakaoma risina bhainda, uye wozoisa chisimbiso kumusoro kwepamusoro pejecha muforoma nefirimu repurasitiki, uchiteverwa nevhu kuti jecha rive rakasimba uye rakasimba. Mushure maizvozvo, bvisa chakuvhuvhu, isa jecha cores, vhara iyo mold kuita everthing yakagadzirira kudira. Pekupedzisira, kurasa kwacho kunowanikwa mushure mekunge simbi yakanyungudutswa yatonhorera uye ikasimbiswa.
2- Ndeapi Iwo Makomborero Ekutsvaira Vacuum?
1) Iyo yekugezesa castings ine yakakwira chikamu cheyakarurama, yakajeka pepa uye rakatsetseka pamusoro.
2) Iko hakuna anosunga, mvura uye zvinowedzera mujecha rekuumba, izvo zvinoita kuti jecha rive nyore.
3) Zviri nyore kuchenesa iyo vacuum castings. Magasi mashoma anokuvadza anogadzirwa panguva yekukanda.
4) Iyo yekugezera castings yaigona kushandiswa pane dzakasiyana maindasitiri. Inogona kushandiswa kune imwechete-chidimbu chidiki batch kugadzirwa pamwe nekugadzira kwakawanda, kunyanya makuru uye epakati-saizi castings uye matete-ane masvingo castings anonyanya kukodzera kuchenesa kukanda.
3- Ndeapi Masimbi neAlloys Zvinogona Kukandwa neVhuvhu Kukanda?
• Grey Cast Iron, Ductile Yakakanda Iron
• Carbon Simbi: Yakadzika kabhoni, yepakati kabhoni uye yakakwira kabhoni simbi
• Cast Alloys yesimbi: Yakadzika chiwanikwa simbi, yakakwira chiwanikwa simbi, yakakosha chiwanikwa simbi
• Aluminium uye alloys avo
Brass & Mhangura.
4- Ndeapi maindasitiri ari iwo ekutsiva iwo mafuro anoshandiswa?
Sezvambotaurwa pamusoro zvakanakira Vacuum Kudzingwa, ari Vacuum castings aigona kushandiswa panguva dzakasiyana-siyana maindasitiri. Inogona kushandiswa kune imwechete-chidimbu chidiki batch kugadzirwa pamwe nekugadzira kwakawanda, kunyanya makuru uye epakati-saizi castings uye matete-ane masvingo castings anonyanya kukodzera kuchenesa kukanda. Naizvozvo, iyo yekuvharira castings inowanzoshandiswa kune zvekurima machineries, hydraulic masystem, njanji yekutakura mota, cranes uye ekuvaka zvikepe maindasitiri.
5- Ndezvipi Kukanda Kushivirira Kunogona Kusvitswa neVhuvhu Kukanda Maitiro?
Munguva yekutsiva kwemhepo, nekuti pamusoro peiyo modhi yakafukidzwa nepurasitiki firimu, hapana chikonzero chekuzunguzika kana kugogodza kana uchidhonza furu. Kukweva uye kwakashata kumanikidza kunoita kuumbwa kwejecha kuumbana, uye kuomarara kwejecha muforoma kwakakwirira uye kwakafanana Pasi pekupisa kwesimbi yakanyungudutswa, iyo mhango haisi nyore kuumbika. Zvakare, kuvepo kwekumanikidza kwakashata kunobatsira pakuzadzwa kwesimbi yakanyungudutswa mumodhidhi. Iyo yepamusoro roughness yeV maitiro castings anogona kusvika Ra = 25 ~ 2.5μm. Iyo yekurebesa shiviriro yezinga revanokanda vanogona kusvika CT5 ~ CT7. Iko kutaridzika kwehunhu hwekumanikidza kwakashata kwakanaka, uye yemukati mhando ndeyechokwadi.
