Muminda yetekinoroji yemazuva ano yekukanda, michina yekukanda vacuum pressure inofarirwa zvikuru nekuda kwekugona kwayo kuvandudza mhando yemidziyo yekukanda. Pakati payo, kugadzira nzvimbo yemuchina wekubvisa vacuum idanho guru rekushanda, iro rinosanganisira magadzirirwo akasiyana-siyana ehunyanzvi uye mashandiro ekushandira pamwe chete kwetekinoroji.

Danho rekutanga pakugadzira nzvimbo yekubvisa mhepo ine vacuum pressure muchina wekubvisa mhepo ndeyekuvaka sisitimu yekuvhara mhepo. Nzvimbo yese yemidziyo yekukanda mhepo, kusanganisira chitofu chine simbi yakanyungudutswa, nzvimbo yechinhu chiri muchimiro, uye mapaipi ekubatanidza, zvinofanirwa kuve nechokwadi chekuti zvinhu zviri muchimiro chakakwirira. Zvinhu zvekuchengetedza zvemhando yepamusoro, zvakaita semaringi ekuchengetedza rabha akakosha, zvinowanzo shandiswa uye kuiswa panzvimbo dzinobatana zvikamu zvakasiyana-siyana zvinobatanidza uye zvinhu zvinofamba kudzivirira mhepo kuti isapinde mukati menguva yekupomba mhepo. Semuenzaniso, panosangana gonhi rechoto negomba, gonhi rekuvhara mhepo rakagadzirwa zvakanaka pamwe chete nerin'i rekuvhara rine saizi yakakodzera uye zvinhu zvinogona kugadzira nzvimbo yakavimbika yekuvharira mhepo mushure mekuvhara gonhi rechoto, zvichiisa hwaro hwemabasa anotevera ekubvisa mhepo.

michina yekukanda vacuum pressure

Tevere, sisitimu yekupomba vacuum inoita basa guru. Sisitimu yekupomba vacuum inonyanya kuve nepombi ye vacuum, mapaipi ane chekuita nayo, uye mavharuvhu. Pombi ye vacuum inzvimbo yemagetsi yekugadzira vacuum, uye inowanzo sanganisira rotary vane vacuum pumps, Roots vacuum pumps, nezvimwewo. Mushure mekunge pombi ye vacuum yatanga, yakabatana nekamuri yemuchina wekukanda kuburikidza nepaipi uye inotanga kuburitsa mweya kubva mukamuri. Padanho rekutanga rekuburitsa mweya, mweya uri mukati mekamuri unenge wakawanda, uye pombi ye vacuum inoburitsa mweya wakawanda nekukurumidza kwekuburitsa. Sezvo mweya uri mukati mekamuri unowedzera kutetepa, mamiriro ekushanda kwepombi ye vacuum achagadziriswa zvichienderana nezvinodiwa zve preset vacuum degree kuti irambe yakagadzikana kupomba uye degree yekupedzisira ye vacuum. Semuenzaniso, pombi ye vacuum ye rotary vane inoshandisa mablades anotenderera mukati kuti ikweve uye idzvanye mweya kubva pa intake port, uye yozoiburitsa kubva pa exhaust port, ichitenderera nguva dzose uye ichideredza kumanikidzwa kwemhepo mukati mekamuri.

Kuyera nekutarisa dhigirii re vacuum kwakakosha mukushanda kwe vacuum. Muchina wekukanda une gauge ye vacuum yakanyatsonaka, iyo inoyera dhigirii re vacuum mukati mekamuri munguva chaiyo uye inodzosera data kune system yekudzora. Sisitimu yekudzora inonyatso tonga mashandiro epombi ye vacuum zvichibva pane kukosha kwe vacuum target. Semuenzaniso, kana dhigirii re vacuum rakayerwa risati rasvika padanho rakatarwa, system yekudzora inowedzera simba repombi ye vacuum kana kuwedzera nguva yekupomba; Kana danho re vacuum rasvika, pombi ye vacuum inopinda mumamiriro ekuchengetedza ekuchengetedza kuti ive nechokwadi chekugadzikana kwenzvimbo ye vacuum. Kazhinji, dhigirii re vacuum rinogona kuwanikwa nemuchina wekukanda we vacuum pressure rinogona kuva rakaderera semakumi e pascals kana kutodzikira. Nzvimbo yakadaro ye vacuum yakawanda inogona kubvisa tsvina yegesi mumold cavity, kuderedza kubatanidzwa kwegasi mumvura yesimbi panguva yekudurura, uye kuvandudza zvakanyanya kunaka kwe castings, kudzivirira kuitika kwezvikanganiso zvakaita se porosity uye looseness.

Pamusoro pezvo, kuti iwedzere kugadzirisa nharaunda ye vacuum uye ive nechokwadi chekuti yakavimbika, muchina wekukanda vacuum pressure unewo mimwe michina yekubatsira uye nzira dzekudzivirira kuchengetedzeka. Semuenzaniso, mafirita anoiswa papombi yekubuda nemhepo kudzivirira guruva, tsvina, nezvimwewo kuti zvisapindwe mupombi ye vacuum uye zvichikanganisa mashandiro ayo uye hupenyu hwebasa; Panguva imwe chete, ine mudziyo wekuona kudonha kwe vacuum, uyo unogona kuona nekukurumidza kana paine kudonha kudiki muchikamu chekuvhara uye woburitsa alarm kuti igadziriswe nenguva. Zvakare, mavharuvhu ekutarisa anowanzoiswa panzvimbo inopinzwa neinobuda ye vacuum pumps kudzivirira kuyerera kwegasi uye kuona kuti system ye vacuum system inoshanda zvakanaka.

Iyomuchina wekudzikisa kumanikidzwa kwevacuumYakabudirira kugadzira nzvimbo yekubvisa tsvina inosangana nezvinodiwa zvemaitiro ekukanda kuburikidza nehurongwa hwakazara hwekusunga, sisitimu ine simba yekupomba tsvina, kuyerwa kwakarurama kwekubvisa tsvina uye kutarisa, pamwe chete nemidziyo yakawanda yekubatsira uye nzira dzekudzivirira kuchengetedzeka. Nzvimbo iyi yekubvisa tsvina inopa mamiriro akanaka kwazvo ekudurura nekugadzira simbi yakanyungudutswa mugomba remould, zvichikonzera kuvandudzika kukuru muhuwandu, hunhu hwemakanika, uye mhando yepamusoro yezvigadzirwa zvakaumbwa. Inobatsira zvikuru kusimudzira indasitiri yekukanda zvinhu kuti ive nemhando yepamusoro uye chaiyo, uye inoita basa rinokosha muminda yakawanda yakadai sendege, kugadzira mota, uye zvishongo.
