Impompo yokufunxa ibhekisa kwisixhobo okanye isixhobo Esisebenzisa iindlela zoomatshini, zomzimba, zekhemikhali okanye zefizikokhemikhali ukutsala umoya kwisikhongozeli esimponthiweyo ukuze kufunyanwe vacuum. Ngokuqhelekileyo, ipompo ye-vacuum sisixhobo sokuphucula, ukuvelisa kunye nokugcina i-vacuum kwindawo evaliweyo ngeendlela ezahlukeneyo. Umsebenzi wempompo ye-vacuum kukususa iamolekyu zegesi ukusuka kwigumbi lokucoca, ukunciphisa uxinzelelo lwegesi kwigumbi lokucoca kwaye yenze ukuba ifikelele kwinqanaba elifunekayo le-vacuum.

Kunye neteknoloji vacuum kwintsimi yemveliso kunye nophando lwezenzululwazi ngokusetyenziswa kweemfuno zoluhlu loxinzelelo ngakumbi nangakumbi, uninzi lwenkqubo yokumpompa ivacuum iqulathe iimpompo ezininzi zokufunxa ukuhlangabezana neemfuno zemveliso kunye nenkqubo yophando lwezenzululwazi emva kokumpompa okuqhelekileyo. Ngoko ke, ukwenzela ukuba kube lula ukusetyenziswa kunye nesidingo seenkqubo ezahlukeneyo zokucoca, iimpompo ezahlukeneyo ze-vacuum ngamanye amaxesha zidibene ngokweemfuno zabo zokusebenza kwaye zisetyenziswe njengeeyunithi zokucoca.

Iyunithi yokucoca iringi yamanzi kwiingcambu zempompo njengempompo ephambili, impompo yeringi yamanzi kuthotho lwempompo yangaphambili kwaye yenziwe. Iyunithi yokucoca i-water ring vacuum ikhethwa njengempompo yokuxhasa impompo yamanzi, kungekuphela nje ukoyisa ipompo enye yeringi yamanzi xa usebenzisa umahluko woxinzelelo olulinganiselweyo (iyunithi yoxinzelelo lomda weyunithi kunomda wempompo yamanzi iphuculwe kakhulu), ukungalunganga komgangatho ophantsi wokutsalwa phantsi koxinzelelo oluthile, kwaye kwangaxeshanye kunye nokugcina impompo yeengcambu inokusebenza ngokukhawuleza, ineenzuzo zesantya esikhulu sokutsalwa.

Ke ngoko, impompo yeringi yamanzi ingasetyenziswa ngokubanzi kwishishini lemichiza kwi-vacuum distillation, i-vacuum evaporation, ukuphelelwa ngamanzi emzimbeni kunye nekristalllization. Umkhenkce ukomisa kushishino lokutya; Iitshiphusi zePolyester zomzi mveliso olulaphu olula; Uvavanyo lokulinganisa ukuphakama okuphezulu kunye nokunye inkqubo ye-vacuum iphakathi.

Ngenxa yokusetyenziswa kweyunithi yokucoca esiye sisebenzisa, ngaphezu koyilo kunye nezinto eziphathekayo zezixhobo, kufuneka sinikele ingqalelo kwimpembelelo yendawo yangaphandle kuyo. Le miba yangaphandle inokushwankathelwa kule miba ilandelayo.

1. Uxinzelelo lomphunga

Uxinzelelo oluphantsi lomphunga kunye nokuguquguquka koxinzelelo kunempembelelo enkulu kumthamo we-vacuum seti yepompo, ngoko ke uxinzelelo lwe-steam akufanele lube ngaphantsi koxinzelelo olufunekayo olusebenzayo, kodwa uyilo lwesakhiwo sesixhobo silungisiwe, ukunyuka okukhulu koxinzelelo lwe-steam akuyi kwandisa umthamo wokupompa kunye ne-vacuum degree.

2. Amanzi okupholisa

Amanzi okupholisa adlala indima ebalulekileyo kwizixhobo ze-vacuum zamanqanaba amaninzi. Amanzi ajiyileyo anokwenza ukuba umphunga ube mninzi. Uxinzelelo oluyinxenye lomphunga wamanzi kuxinzelelo lokukhupha luyimfuneko ukuba lube phezulu kunoxinzelelo olupheleleyo lomphunga oluhambelanayo.

3. umlomo

Umbhobho yinxalenye ebalulekileyo echaphazela ukusebenza kwezixhobo ze-vacuum. Iingxaki ezikhoyo zezi: i-nozzle ifakwe ngokungalunganga, ifakwe igoso, ivaliwe, yonakaliswe, i-corrosion kunye nokuvuza, ngoko kufuneka sizame ukuphepha.

4. kokusingqongileyo

Imo engqongileyo yeyunithi yempompo yokufunxa ikakhulu ibhekisa kungcoliseko lwenkqubo ngerhasi emponthiweyo. Kule nkqubo, ezinye iincinci ezincinci, ezifana nesikhumba esincinci se-oxidized powder, ziya kuphefumlelwa, kwaye ezi zincinci ezincinci ziya kuqokelela kwaye zinamathele kumzimba wempompo, ukunciphisa ukuhamba kombhobho wokufunxa, ukwandisa ixesha lokupompa, kunye nokunciphisa amandla okupompa kwempompo.
