Kwizicelo zevacuum yemizi-mveliso, ukugcina ukucoceka kwendawo yevacuum kubalulekile ekuqinisekiseni ukuzinza kwenkqubo yemveliso kunye nomgangatho wemveliso. Nangona kunjalo, kwiimeko ezininzi zamashishini, iimpompo ze-vacuum zihlala zisebenza phambi komswakama, i-condensate, okanye i-process fluids, enokuthi ibe nefuthe elibi kakhulu ekusebenzeni kakuhle kwenkqubo yokucoca. Ke ngoko, ukuhluza ngokufanelekileyo kunye nokunyanga olu lwelo lubalulekile ekuqinisekiseni ukusebenza kakuhle kwezixhobo kunye nokuthembeka kwemveliso.
Ukuba awusebenzisi impompo yeringi yolwelo, akukho mathandabuzo ukuba ulwelo luya kuchaphazela impompo yevacuum. Ufuna uncedo lweisahluli segesi-ulwelo.
Ulwelo luzonakalisa njani iiNkqubo zeVacuum?
1. UlweloUkungena kwisixokelelwano sevacuum kunokubangela iingxaki ezininzi:
① Umngcipheko wokonakaliswa komatshini: Xa impompo yokufunxa impompa umoya, ulwelo olukwimekobume lunokutsalwa ngokuthe ngqo kwimpompo. Olu lulwelo lunokudityaniswa nezinto ezichanekileyo zoomatshini (ezinje ngeerobhothi kunye neeblades), ezikhokelela ku:
- I-Corrosion yeendawo zetsimbi (ingakumbi kwimizimba yempompo yensimbi engenasici);
- I-Emulsification ye-lubricant (intsebenzo yokuthambisa iyancipha ngama-40% xa umthamo wamanzi kwi-lubricant udlula i-500 ppm kwiimpompo ezifakwe i-oyile);
- I-slugging yolwelo (umonakalo womzimba kwiibheringi kunye nezitywina ezibangelwa ukunyanzeliswa kolwelo oludlulayo);
② Ukusebenza kwevacuum okuthotyiweyo: Ukungcoliseka kolwelo kunokukhokelela:
- Ukunciphisa i-vacuum yokugqibela (umphunga wamanzi uxinzelelo oluyinxenye yenza kube nzima ukufezekisa i-vacuum engaphantsi kwe-23 mbar kwi-20 ° C);
- Ukunciphisa ukusebenza kakuhle kokupompa (isantya sokumpompa iimpompo ze-oyile-lubricated zingahla nge-30-50%);
③Ingozi yokungcoliseka kwenkqubo (umzekelo, kwiinkqubo zokugquma, imixube ye-oyile-amanzi inokubangela imingxunya kwifilimu);
2. Iimpawu ezithile zeumphungaiziphumo
Njengoko kukhankanyiwe ngaphambili, kungekhona kuphela ulwelo ngokwawo, kodwa kunye nemiphunga ephuphumayo phantsi kwefuthe le-vacuum inokuchaphazela ukusebenza okuqhelekileyo kwempompo yokucoca.
- Yandisa umthwalo wegesi ojiyayo;
- Phinda u-liquefy ngexesha lenkqubo yoxinzelelo, ukwenza i-emulsions yeoli yepompo;
- I-Condensate kwiindawo ezibandayo, zingcolise igumbi lokusebenza.
Ngamafutshane, ukususwa kwamanzi linyathelo elibalulekileyo neliyimfuneko kwi-vacuum yemizi-mveliso. Ukuhlohla aisahluli segesi-ulweloikhusela ngokufanelekileyo ulwelo ekungeneni kwimpompo ye-vacuum, ukukhusela ukusebenza okuqhelekileyo kwesixhobo. Ngaphezu koko, ukususa ulwelo kwindawo yokucoca kunceda ukugcina inqanaba elizinzileyo le-vacuum kunye nokuqinisekisa ukusebenza kakuhle kwemveliso.Ngomphunga wamanzi, sinokuyisusa ngokufanelekileyo ngoncedo lokupholisa ulwelo okanye i-chiller. Ukuqwalaselwa kwezi nkcukacha ngexesha lokusebenza kubalulekile ukuqinisekisa ukuzinza kwexesha elide lempompo yokucoca.
