Mumunda wemazuva ano ekukanda tekinoroji, vacuum pressure yekukanda michina inofarirwa zvakanyanya nekugona kwavo kunyatso kuvandudza mhando yekukanda. Pakati pavo, kugadzira nharaunda yevacuum idanho rakakosha rekushanda, iro rinosanganisira nhevedzano yeakaomesesa magadzirirwo uye tekinoroji kushandira pamwe.

Nhanho yekutanga mukugadzira nharaunda yevacuum ine vacuum pressure yekukanda muchina kuvakwa kwechisimbiso system. Iyo yese mhango yemidziyo yekukanda, kusanganisira crucible ine simbi yakanyungudutswa, iyo mold mugodhi panowanikwa mold, uye mapaipi ekubatanidza, inofanirwa kuve nechokwadi chepamusoro chisimbiso. Zvinhu zvekuvharisa zvemhando yepamusoro, zvakadai sezvindori zvekuvhara rabha, zvinowanzo shandiswa uye kuiswa pamajoini ezvikamu zvakasiyana-siyana zvinosungirirana uye zvinofambisa zvinhu kudzivirira mhepo kuti isapinda panguva yekupomba kwevacuum. Semuenzaniso, panosangana mukova wechoto uye mhango, yakanyatsogadzirwa chisimbiso groove yakasanganiswa nemhete yekuisa chisimbiso yehukuru hwakakodzera uye zvinhu zvinogona kuumba yakavimbika yekuisa chisimbiso interface mushure mekuvhara gonhi rechoto, nekuisa hwaro hwekuzotevera vacuum kubviswa mashandiro.

Zvadaro, vacuum pumping system inoita basa repakati. Iyo vacuum yekupomba sisitimu inonyanya kuve nepombi yevacuum, mapaipi ane hukama, uye mavharuvhu. Pombi yevacuum inzvimbo ine simba rekugadzira vacuum, uye yakajairika inosanganisira rotary vane vacuum pumps, Roots vacuum pumps, etc. Mushure mekunge pombi yekutsvaira yatangwa, inobatanidzwa nekamuri yemuchina wekukanda kuburikidza nepombi uye inotanga kuburitsa. mweya kubva mukamuri. Muchikamu chekutanga chekubudiswa kwemhepo, mhepo iri mukati mekamuri inenge yakaoma, uye pombi yevacuum inobvisa huwandu hwemhepo pahuwandu hwekuwedzera. Sezvo mhepo iri mukati mekamuri zvishoma nezvishoma ichiva mutete, mamiriro ekushanda epombi yevacuum inogadziriswa zvinoenderana neyakagadzirirwa vacuum degree zvinodiwa kuchengetedza yakagadzikana yekupomba kumhanya uye yekupedzisira vacuum degree. Semuenzaniso, rotary vane vacuum pombi inoshandisa mashizha anotenderera mukati kukwevera mukati uye kumanikidza mweya kubva pachiteshi chekupinza, uye wobva waiburitsa kubva pachiteshi chekuburitsa, ichienderera ichitenderera uye ichidzikisa kudzvanywa kwemhepo mukati mekamuri.

Iko kuyerwa uye kutarisa kwedhigirii yevacuum kwakakosha mukuita kwekutsvaira. Muchina wekukanda wakashongedzerwa neakakwira-chaiyo vacuum gauge, iyo inoyera iyo vacuum dhigirii mukati mekamuri munguva chaiyo uye inodzosera iyo data kune yekudzora sisitimu. Iyo yekudzora sisitimu inonyatso gadzirisa kushanda kwepombi yevacuum zvichienderana neyakaiswa vacuum chinangwa kukosha. Semuenzaniso, kana iyo yakayerwa vacuum dhigirii isati yasvika payakatemerwa mwero, hurongwa hwekutonga huchawedzera simba repombi yekutsvaira kana kuwedzera nguva yekupomba; Kana iyo yakanangwa vacuum level yasvika, iyo vacuum pombi inopinda munzvimbo yekuchengetedza inoshanda kuti ive nechokwadi chekugadzikana kwenzvimbo yevacuum. Kazhinji kutaura, iyo vacuum dhigirii iyo vacuum yekumanikidza yekukanda muchina inogona kudzika semakumi epascals kana kutodzika. Yakadaro yakakwira vacuum nharaunda inogona kunyatso bvisa gasi tsvina mu mold cavity, kuderedza kubatanidzwa kwegasi mumvura yesimbi panguva yekudurura, uye zvakanyanya kunatsiridza kunaka kwekukanda, kudzivirira kuitika kwehurema hwakadai se porosity uye looseness.

Pamusoro pezvo, kuitira kuti uwedzere kukwidziridza nharaunda yevacuum uye kuve nekuvimbika kwayo, iyo vacuum pressure casting muchina inoshongedzerwawo nemimwe michina yekubatsira uye nzira dzekuchengetedza kuchengetedza. Semuyenzaniso, mafirita akaiswa papombi yekuburitsa kudzivirira huruva, tsvina, nezvimwewo kubva pakuyamwa mupombi yevacuum uye kukanganisa kushanda kwayo uye hupenyu hwebasa; Panguva imwecheteyo, yakashongedzerwa nemudziyo wekuona kuputika kwevacuum, iyo inogona kukurumidza kuona kana pane kudonha kudiki muchikamu chekuisa chisimbiso uye kuburitsa alarm kuti igadziriswe nenguva. Zvakare, cheki mavharuvhu anowanzo kuisirwa pane inopinza uye yekubuda yevacuum pombi kudzivirira gasi kudzosera uye kuve nechokwadi chekushanda kwakajairika kwevacuum system.

Thevacuum pressure casting machineyakabudirira kugadzira nzvimbo yevacuum inosangana nezvinodiwa zvekukanda kuburikidza nehuwandu hwekuvhara chisimbiso, ine simba yevacuum pumping system, chaiyo vacuum kuyerwa uye kutarisa, pamwe chete nenhevedzano yezvishandiso zvekubatsira uye nzira dzekuchengetedza kuchengetedza. Iyi nharaunda yevacuum inopa yakanyanya kunaka mamiriro ekudururwa uye kuumbwa kwesimbi yakanyungudutswa mugomba remuvhu, zvichikonzera kuvandudzwa kwakakosha mukuwanda, zvivakwa zvemuchina, uye kunaka kwepamusoro kwezvigadzirwa zvakakandwa. Inosimudzira kusimudzira kweindasitiri yekukanda yakanangana nemhando yepamusoro uye nemazvo, uye inoita basa rinokosha mundima dzakawanda dzakadai seaerospace, kugadzira mota, uye zvishongo.
