Pachava nekuremara mune chero kuumbwa.Kuvapo kwekuremara uku kuchaunza njodzi huru yakavanzika kune yemukati mhando yekukanda.Kugadziriswa kwewelding kubvisa kukanganisa uku mukugadzira kunounzawo mutoro wakakura kune maitiro ekugadzira..Kunyanya, sezvo vharuvhu iri yakaonda-shell casting iyo inoiswa pasi pekumanikidzwa uye tembiricha, iyo compactness yemukati maumbirwo ayo akakosha zvikuru.Naizvozvo, kukanganisa kwemukati kwekukanda kunove chinhu chinogadzirisa chinokanganisa kunaka kwekukanda.
Kukanganisa kwemukati kwekukanda kwevhavha kunonyanya kusanganisira pores, slag inclusions, shrinkage porosity uye kuputika.
Pano ichasuma imwe yekuremara kukuru -----Pores uye shrinkage porosity
(1) Maburi:
Mapores anogadzirwa negasi, pamusoro pegomba rakatsetseka, uye rinogadzirwa mukati kana padyo nepamusoro pekukanda, uye chimiro chakanyanya kutenderera kana ovha.
Nzvimbo huru dzegasi dzinogadzira pores ndeidzi:
①Iyo nitrogen nehydrogen yakanyungudutswa musimbi iri musimbi panguva yekugadzika kwekukanda, ichigadzira yakavharwa denderedzwa kana ovha yemukati madziro ane esimbi inopenya pores.
②Kunyorova kana kuvhuvhuta zvinhu mumhando yekuenzanisira inozova gasi nekuda kwekudziya, kugadzira pores ane rima remukati madziro.
③ Panguva yekudurura kwesimbi, nekuda kwekuyerera kusina kugadzikana, mweya unobatanidzwa kuumba pores.
Nzira yekudzivirira Pores defects:
①Mukunyungudutsa, shandisa simbi isina ngura zvishoma kana isina sezvaunokwanisa, uye bheka nekuomesa maturusi neladle.
②Simbi yakanyungudutswa inofanira kuburitswa patembiricha yakakwira uye yodururwa patembiricha yakaderera, uye simbi yakanyungudutswa inofanira kudzikamiswa zvakanaka kuti ifambise kuyerera kwegasi.
③ Magadzirirwo emubato wekudira anokwira anofanira kuwedzera kumanikidza musoro wesimbi yakanyungudutswa kudzivirira kupindira kwegasi, uye kumisikidza nzira yegasi yekuburitsa zvine musoro.
④Iyo yekuumba inofanirwa kudzora zvirimo zvemvura uye gasi kugadzirwa, kuwedzera mhepo kupera, uye jecha mold uye jecha musimboti zvinofanirwa kubikwa nekuomeswa zvakanyanya sezvinobvira.
(2)Shrinkage mhango (yakasununguka):
Iyo inobatana kana inorega denderedzwa kana isina kukwana mhango (cavity) mukati mekukanda (kunyanya pajojo rinopisa), ine rough mukati mepamusoro uye yakasviba ruvara.Mbeu dzakakasharara, kazhinji madendrites, uye dzinoungana munzvimbo imwe kana kupfuura, uye kudonha kuri nyore kuitika panguva yekuyedza hydraulic.
Chikonzero che shrinkage cavity (yakasununguka):
vhoriyamu inodzikira kana simbi yaomeswa kubva pamvura ichienda kune yakasimba.Iyo shrinkage mhango yekukanda simbi inokonzeresa nekutonga kusiri iko kwesequential solidification process, iyo inogona kukonzerwa nekumisikidza kwakashata kwekusimuka, tembiricha yepamusoro yekudururwa kwesimbi yakanyungudutswa, uye kupera kwesimbi huru.
Nzira dzekudzivirira shrinkage cavities (yakasununguka):
① Nesainzi gadzira iyo yekukanda sisitimu kuitira kuti simbi yakanyungudutswa igone kusimba zvakatevedzana, uye chikamu chekutanga chakaomeswa chinofanira kuwedzerwa nesimbi yakanyungudutswa.
②Nemazvo uye zvine musoro kuseta masimuriro, rubatsiro, uye mukati nekunze simbi inotonhora kuti ive nechokwadi chekutevedzana kusimba.
③Kana uchidira simbi yakanyungudutswa, pakupedzisira ichidurura kubva pamusoro pechikwiriso chinobatsira pakuona tembiricha uye kudya kwesimbi yakanyungudutswa, uye kuderedza kugadzirwa kwemakomba ekupwanya.
④Panyaya yekudurura kumhanya, kudira kwakaderera-kumhanya kunobatsira mukutevedzana kusimba pane kudira-kumhanya kukuru.
⑤Tembiricha yekudira haifanire kunge yakanyanya kukwira.Simbi yakanyungudutswa inoburitswa patembiricha yakakwira uye inodururwa mushure mekunyorovesa, izvo zvinobatsira kudzikisa shrinkage cavities.
KUSANGANA KUDZOKERA CHECK VAVIVE
Swing cheki mavharuvhuari pakati peakajairika marudzi echeki mavharuvhu uye anowanzo shandiswa kugadzirisa yakakwira yakatwasuka kuyerera.
Kudzvinyirirwa kwemvura kunovhura dhisiki kuti mvura kana gasi ripinde.
Mushure mekunge kuyerera kwamira, dhisiki inotenderera ichidzokera munzvimbo yayo yakavharwa, ichizorora pakatarisana nechigaro chevhavha uye ichidzivirira kudzoka shure.
Kudzvinyirirwa kweyese-kudzokera shure kunoshandawo kuvhara disc.
