Ii-screw chillers zinokwahlulwa zibe zii-screw chillers ezipholisiweyo ngumoya kunye nee-screw chillers ezipholisiweyo ngumanzi ngokweendlela ezahlukeneyo zokusasaza ubushushu. I-screw chiller epholisiweyo ngumanzi isebenzisa inkqubo yokujikeleza kwamanzi ye-cooling tower ukuze isasaze ubushushu, ngelixa i-screw chiller epholisiweyo ngumoya isebenzisa umoya ocoliweyo ukuze isasaze ubushushu. Ngexesha lokusebenza kweyunithi, ngokuqinisekileyo kuya kubakho ukungcola okuthile ngenxa yomgangatho wamanzi okanye iingxaki zomoya, okanye ngenxa yokuba ioyile efrijini imdaka, nto leyo eya kuchaphazela yonke inkqubo yokufriji. Yenza ukucoca nokulungisa.
Ngoko ke, ungayicoca njani inkqubo yokukhenkceza ye-screw chiller?
1. Ungafumanisa njani ukuba inkqubo yokukhenkcisa ye-screw chiller kufuneka icocwe?
Okokuqala, kufuneka sijonge ukuba ingaba umbala weoyile yeoyile yokupholisa icompressor yescrew chiller ujika ube mdaka na? Ukuba kunjalo, kuthetha ukuba umgangatho weoyile unamafu. Okwesibini, jonga ukuba ivumba litshile na, kwaye ujonge ixabiso lokumelana kwenjini yokupholisa kwicompressor. Ukuba ixabiso lokumelana phakathi kwe-winding kunye neqokobhe liqhelekile, kuthetha ukuba i-insulation ilungile. Ngaphandle koko, ioyile yokupholisa kufuneka itshintshwe kwaye inkqubo yokupholisa kufuneka icocwe.
Apha, ndingathanda ukukhumbuza wonke umntu: Kwinkqubo yamanzi ye-chiller, ukungcola kuya kunamathela eludongeni lwangaphakathi lombhobho kancinci okanye kancinci. Ukuba iyunithi isebenza ixesha elide kwaye kukho ukungcola okuninzi, isihluzo sokomisa siya kuvalwa kwaye iyunithi ayiyi kukwazi ukupholisa. Ke ngoko, kucetyiswa ukucoca i-heat exchanger rhoqo emva kweenyanga ezintandathu kunye nokucoca inkqubo minyaka le.
2. Yintoni ekufuneka yenziwe ngaphambi kokucoca inkqubo yokukhenkcisa?
Kwindawo engcolileyo kwipayipi yenkqubo yokukhenkceza, iarhente yokucoca ingasetyenziselwa ukuyicoca. Ngaphambi kokucoca, kuyimfuneko ukukhulula i-refrigerant kwinkqubo yokukhenkceza, emva koko ususe i-compressor, kwaye uthulule ioyile ye-refrigerant kumbhobho wenkqubo. Ngexesha lokusebenza kokucoca, qala ususe i-compressor kunye ne-dry filter, uze ukhuphe i-capillary (okanye i-expansion valve) kwi-evaporator, uqhagamshele i-evaporator kwi-condenser ngepayipi enganyangekiyo kuxinzelelo, uze usebenzise i-A hose uqhagamshela izixhobo zokucoca ngokuqinileyo nemibhobho yokufunxa nokukhupha ye-compressor. Emva koko coca izixhobo ezisetyenzisiweyo, ezinje ngeempompo, iitanki, izihluzi, ii-dryers, kunye neevalvu ezahlukeneyo.
Inkqubo yokucoca yile ilandelayo: qala ufake isixhobo sokucoca kwitanki engamanzi, uze uqalise ipompo, uyenze isebenze, uze uqale ukucoca. Xa ucoca, yenza imisebenzi emininzi phambili nangasemva de isixhobo sokucoca singabonisi iasidi. Kungcoliseko oluncinci, kufuneka sijikeleze malunga neyure e-1 kuphela. Kungcoliseko olunzima, kuthatha iiyure ezi-3-4. Ukuba sicociwe ixesha elide, isixhobo sokucoca singcolile, kwaye nesihluzo sivalekile kwaye singcolile. Isixhobo sokucoca kunye nesihluzo kufuneka zitshintshwe ngaphambi kokuba kwenziwe lo msebenzi. Emva kokuba inkqubo icociwe, isixhobo sokucoca singcolile kwaye nesihluzo sivalekile kwaye singcolile. Isixhobo sokucoca esikwindawo yokugcina ulwelo kufuneka sibuyiswe kumbhobho wolwelo. Emva kokucoca, ukuvuthela kunye nokomisa i-nitrogen kufuneka kwenziwe kumbhobho wokufriji, uze uzaliswe nge-fluorine, kwaye kufuneka kwenziwe umsebenzi wokulungisa ii-unit ukuqinisekisa ukusebenza okuqhelekileyo kwesitshizi.
Amandla e-screw chiller makhulu kakhulu, kwaye kukho ukhetho lwe-single head okanye i-double head. I-single-head screw chiller ine-compressor enye kuphela, enokulungiswa ngamanqanaba amane ukusuka kwi-100% ukuya kwi-75% ukuya kwi-50% ukuya kwi-25%. I-twin-head screw chiller yenziwe ngee-compressors ezimbini kwaye ineenkqubo ezimbini ezizimeleyo. Xa enye yazo ingaphumeleli okanye ifuna ukulungiswa, enye ingasetyenziswa ngokuqhelekileyo, nto leyo elula kakhulu ukuyisebenzisa.
