Iphampu yevacuum isho idivaysi noma okokusebenza ESEBENZISA izindlela zomshini, ezomzimba, zamakhemikhali noma ze-physicochemical ukukhipha umoya esitsheni esimpontshwayo ukuze kutholakale i-vacuum. Ngokuvamile, iphampu ye-vacuum iyithuluzi lokuthuthukisa, ukukhiqiza nokugcina i-vacuum endaweni evaliwe ngezindlela ezihlukahlukene. Umsebenzi wephampu ye-vacuum ukukhipha ama-molecule egesi ekamelweni le-vacuum, ukunciphisa ingcindezi yegesi ekamelweni lokuphumula futhi ulenze lifinyelele izinga elidingekayo le-vacuum.

Ngobuchwepheshe be-vacuum emkhakheni wokukhiqiza kanye nocwaningo lwesayensi mayelana nokusetshenziswa kwezidingo zobubanzi bengcindezi ngokuya ngokubanzi, iningi lesistimu yokumpompa i-vacuum iqukethe amaphampu we-vacuum amaningana ukuhlangabezana nezidingo zokukhiqiza kanye nenqubo yocwaningo lwesayensi emva kokupompa okuvamile. Ngakho-ke, ukuze kube lula ukusetshenziswa kanye nesidingo sezinqubo ezihlukahlukene ze-vacuum, amaphampu e-vacuum ahlukahlukene ngezinye izikhathi ahlanganiswa ngokuvumelana nezidingo zabo zokusebenza futhi asetshenziswe njengamayunithi e-vacuum.

Iyunithi yevacuum yendandatho yamanzi empompeni yezimpande njengepompo eyinhloko, iphampu yeringi yamanzi yochungechunge lwephampu yangaphambili futhi yakhiwe. Iyunithi ye-vacuum yendandatho yamanzi ikhethwa njengepompo yokusekela iphampu yamanzi endandatho, hhayi nje ukunqoba ipompo elilodwa lendandatho yamanzi uma usebenzisa umehluko wengcindezi yomkhawulo (ingcindezi yomkhawulo weyunithi kunomkhawulo wepompo lendandatho yamanzi isithuthuke kakhulu), ukungasebenzi kwezinga eliphansi lokukhipha ngaphansi kwengcindezi ethile, futhi ngesikhathi esifanayo nokugcina iphampu yezimpande ingasebenza ngokushesha, inezinzuzo zesilinganiso esikhulu sokukhipha.

Ngakho-ke, iphampu yendandatho yamanzi ingasetshenziswa kabanzi embonini yamakhemikhali ku-vacuum distillation, i-vacuum evaporation, ukuphelelwa amandla kwamanzi kanye ne-crystallization. Ukumisa iqhwa embonini yokudla; Ama-polyester chips embonini yendwangu ekhanyayo; Ukuhlolwa kokulingisa kokuphakama okuphezulu nokunye uhlelo lwe-vacuum luphakathi.

Ngomphumela wokusetshenziswa kweyunithi ye-vacuum ebesiyisebenzisa, ngaphezu kokuklama nezinto ezisetshenziswayo, kufanele sinake ithonya lendawo yangaphandle kuyo. Lezi zici zangaphandle zingafingqwa zibe yizici ezilandelayo.

1. Umfutho we-steam

Umfutho ophansi we-steam kanye nokuguquguquka kwengcindezi kunomthelela omkhulu kumthamo wesethi yepompo ye-vacuum, ngakho-ke umfutho we-steam akufanele ube ngaphansi kwengcindezi yokusebenza edingekayo, kodwa ukwakheka kwesakhiwo semishini kulungisiwe, ukwanda kakhulu komfutho we-steam ngeke kwandise umthamo wokupompa kanye ne-vacuum degree.

2. Amanzi okupholisa

Amanzi okupholisa adlala indima ebalulekile emishinini ye-vacuum enezigaba eziningi. Amanzi ajiyile angabamba isitimu esiningi. Ukucindezela okuyingxenye komhwamuko wamanzi ekucindezelweni kokukhipha kuyadingeka ukuze kube phezulu kunokucindezela okugcwele kwesitimu okuhambisanayo.

3. umbhobho

I-nozzle iyingxenye ebalulekile ethinta ukusebenza kwemishini ye-vacuum. Izinkinga ezikhona yilezi: i-nozzle ifakwe ngokungalungile, ifakwe igwegwile, ivinjiwe, yonakalisiwe, i-corrosion kanye nokuvuza, ngakho-ke kufanele sizame ukugwema.

4. imvelo

Imvelo yeyunithi yepompo ye-vacuum ibhekisela ikakhulukazi ekungcolisweni kwesistimu yigesi elimpontshwayo. Kule nqubo, ezinye izinhlayiya ezincane, njengesikhumba sempushana esine-oxidized, zizohogela, futhi lezi zinhlayiya ezincane zizonqwabelana futhi zinamathele emzimbeni wepompo, zinciphise ukugeleza kwepayipi lokudonsa, kunwebe isikhathi sokupompa, futhi kunciphise amandla okupompa epompo.
