Ukuhlelwa kweoli yefriji
Enye yioli yemveli yeminerali;
Enye i-synthetic polyethylene glycol esters ezifana ne-PO, i-oyile ye-Polyester nayo i-polyethylene glycol yokwenziwa kwe-oyile yokuthambisa. I-oyile ye-POE ingasetyenziselwa kuphela kwinkqubo yefriji ye-HFC, kodwa nakwi-hydrocarbon refrigerant.PAG yeoli ingasetyenziswa kwi-HFC, i-hydrocarbon kunye ne-ammonia iinkqubo njenge friji.
Umsebenzi oyintloko weoli yefriji
·Nciphisa umsebenzi wokukhuhlana, ubushushu bokungqubana nokuguga
·Gcwalisa indawo yokutywina ngeoyile ukuqinisekisa ukusebenza kokutywina kunye nokuthintela ukuvuza kwefriji.
·Ukushukuma kwe-oyile kususa amasuntswana abrasive aveliswa kukukhuhlana kwesinyithi, ngaloo ndlela kucocwa umphezulu wokukhuhlana.
·Bonelela ngamandla okwenziwa ngolwelo olwenziwa ngamanzi okusebenza ngendlela yokothula
Iimfuno zokusebenza kwi-oyile efrijini
·I-viscosity efanelekileyo: i-viscosity ye-oyile yomatshini wefriji ayiqinisekisi nje kuphela ukuba i-friction surface yendawo nganye ehambayo ine-lubricity elungileyo, kodwa iphinda isuse ubushushu obuthile kumatshini wokucoca kwaye idlala indima yokutywina. Ukunyibilika okukhulu kwi-oyile yomatshini wokukhenkceza, i-oyile ene-viscosity ephezulu kufuneka ithathelwe ingqalelo ukoyisa impembelelo yeoyile ehlanjululwe sisibandisi.
Incinci eguquguqukayo, inqanaba eliphezulu le-flash point: i-oyile enomkhenkce eguquguqukayo inkulu, kunye nomjikelo wefriji, ubungakanani be-oyile, ngakumbi amaqhezu e-oyile yefriji, uluhlu olumxinwa kakhulu lwendawo yokukhanya kufuneka lube phezulu kunobushushu bomatshini obungaphezulu kwama-25 ~ 30. ℃.
Uzinzo oluhle lweekhemikhali kunye nozinzo lwe-oxidation ye-thermal: kumatshini wokugqibela wokuxinzelela ubushushu obusebenzayo yi-130 ℃ ~ 160 ℃, iqondo lokushisa kweoli ekhenkcezayo kunye nokubola kwe-metamorphism eqhubekayo, ukuvelisa idiphozithi yekhabhoni kwifriji yokungasebenzi kakuhle kunye nokunxiba.Ngaphezu koko, ukubola. iimveliso zeoli ziya kusabela kunye nefriji, eya kwenza umphumo wokupholisa ube nzima ngakumbi, kwaye i-asidi ebangelwayo iya kutshabalalisa kakhulu iindawo zefriji.
·Akukho manzi kunye nokungcola: ngenxa yokuba amanzi efriza kwi-evaporator iya kuchaphazela ukusebenza kakuhle kokufudumeza, ukudibanisa nefriji kuya kukhawulezisa ukubola kwefriji kunye nokutshabalalisa izixhobo, ngoko ke ioli efrijini ayinakuquka amanzi kunye nokungcola.
·Ezinye: I-oyile yokukhenkceza kufuneka ibe nepropathi elungileyo yokuchasa ugwebu kwaye inganyibiliki okanye yandiswe ibe yirabha, ucingo olunameleli kunye nezinye izinto. Ukugqunywa kombane okufanelekileyo kufuneka kusetyenziswe kumatshini ofakwe efrijini.
Izinto ekufuneka ziqwalaselwe ekukhetheni ioli yokukhenkceza
·I-Viscosity: isantya esiphezulu se-compressor, iphezulu i-viscosity yeoli efrijini kufuneka ibe njalo.
·Ukuzinza kwe-Thermal:Uzinzo lwe-thermal ngokuqhelekileyo lulinganiswa ne-flash point ye-oyile ye-injini enomkhenkce.Indawo yokukhanya ibhekiselele kwiqondo lobushushu apho umphunga we-oyile yomatshini wokukhenkceza udanyaza emva kokuba ushushu. Iqondo lobushushu lokukhupha icompressor, elifana ne-R717, i-R22 compressor usebenzisa i-flash point ye-oyile yefriji kufuneka ibe ngaphezulu kwe-160 ℃.
Ulwelo olumanzi: i-oyile yomatshini wokukhenkceza kufuneka ibe nolwelo olulungileyo kwiqondo lobushushu eliphantsi.Kwi-evaporator, ngenxa yeqondo lokushisa eliphantsi kunye nokwanda kwe-viscosity yeoli, i-fluidity iya kuba yimbi.Xa ioli yomshini wefriji ifikelela kubushushu obuthile, iya kuyeka ukuhamba.Indawo yokukhenkceza ye-oyile yomatshini wokucoca iyadingeka ukuba ibe phantsi, ngokukodwa indawo yokukhenkceza yeoli yomatshini we-cryogenic ibaluleke kakhulu.
·Ukunyibilika: ukunyibilika kweefriji ezahlukeneyo kunye ne-oyile yesikhenkcisi kwahlukile, ezinokuthi zahlulwe ngokweendidi ezintathu: enye ayinyibiliki, enye ayinyibiliki, kwaye enye iphakathi kwezi zimbini zingasentla.
·Indawo ye-Turbidity: iqondo lobushushu apho i-oyile yesikhenkcezisi iqala khona ukukhupha iparafini (i-oyile iba yi-turbid) ibizwa ngokuba yi-turbidity point.Xa kukho isibandisi, indawo yokuxubha kweoli yefriji iya kuncipha.
Eyona nto ibangela ukuwohloka kweoli efrijini
·Ukuxuba amanzi: ngenxa yokungenwa komoya kwisistim somoya, amanzi asemoyeni axutywa neoyile yomatshini wokucoca emva kokudibana.Umthamo wamanzi kwifriji uphezulu, nawo unokuxuba amanzi kwioyile yefriji.Xa amanzi exutywa kwifriji. ioli efrijini, i-viscosity iyancipha kwaye intsimbi iyancipha.Kwinkqubo yefriji ye-freon, "iplagi yeqhwa" nayo ibangelwa.
·I-oxidation: xa kusetyenziswa i-oyile yokukhenkceza, xa iqondo lobushushu le-compressor yokuphuma liphezulu, kunokubangela ukuwohloka kwe-oxidative, ngakumbi i-oyile ekhenkcezayo enozinzo olulambathayo kwikhemikhali, ethanda ukuwohloka ngakumbi.Ngethuba lexesha, i-residus iya kwenziwa kwi-oyile efrijini, ebangela ukuba i-lubrication yeebheringi kunye nezinye iindawo zibe zibi.
Ukuxuba i-oyile yomatshini wokukhenkceza: xa iintlobo ezininzi ezahlukeneyo zeoli yomatshini wokucoca zisetyenziselwa kunye, i-viscosity ye-oyile yomatshini wokucoca iya kuncitshiswa, kwaye kunye nokubunjwa kwefilimu yeoli kuya konakala.
Ukuba iintlobo ezimbini zeoyile yomatshini wokukhenkceza ziqulethe izongezo ezichasene ne-oxidation zeempawu ezahlukeneyo, xa zixutywe kunye, utshintsho lweekhemikhali lunokwenzeka kwaye i-precipitates iya kwenziwa, eya kuchaphazela ukuthambisa kwecompressor.Ngoko ke, ingqalelo kufuneka ihlawulwe xa usebenzisa.
Kukho ukungcola kwi-oyile efrijini
Indlela yokukhetha ioli yefriji
·Khetha i-oyile yokuthambisa ngokohlobo locinezelo: icompressor yomatshini wokukhenkceza ineentlobo ezintathu zepiston, screw kunye necentrifugal.Iindidi ezimbini zokuqala zeoli yokuthambisa zidibene ngokuthe ngqo kunye nefriji ecinezelweyo, ngokuqwalasela intsebenziswano phakathi kweoli yokuthambisa kunye neoli ye-refrigerant.Centrifugal isetyenziselwa kuphela ukuthambisa i-rotor bear.Inokuthi ikhethwe ngokomthwalo kunye nesantya.
·Khetha ioli yokuthambisa ngokohlobo lwefriji: ioli yokuthambisa ngokuthe ngqo kunye nefriji kufuneka iqwalasele ukusebenzisana phakathi kwezi zimbini.Ngokomzekelo, ifriji efana nefreon inokunyibilika kwioli yamaminerali, ngoko ke ibakala le-viscosity ye-lubricating ekhethiweyo. I-oyile kufuneka ibe yinqanaba eliphezulu kunelo lefriji enganyibilikiyo, ukwenzela ukuba ioli yokuthambisa ingakwazi ukuqinisekiswa emva kokuba ihlanjululwe. Ukongeza, kufuneka kuqatshelwe ukuba ioli encinci yokuthambisa ixutywe nefriji iya kuchaphazela umsebenzi wenkqubo yefriji.I-flocculation point of refrigerating oil machine is isalathisi somgangatho ukujonga ukuba i-oyile yokuthambisa exutywe ne-refrigerant inokunciphisa i-wax crystal kwaye ivimbele inkqubo yefriji.
Khetha ioyile yokuthambisa ngokweqondo lobushushu lesikhenkcezisi ngokobushushu bomphunga: xa sithetha nje jikelele, i-evaporator enesikhenkcezisi enobushushu obuphantsi bomphunga kufuneka ikhethe i-oyile yefriji enendawo yokukhenkceza ephantsi, ukuze kuthintelwe i-oyile yokuthambisa ethwalwa sisikhenkcezisi isise kwisikhenkcezisi ekujikeni kwi-throttle. ivalve kunye ne-evaporator, echaphazela ukusebenza kakuhle kwefriji.
Indawo yokukhenkceza ye-oyile yokuthambisa esetyenziswa kwisibandisi se-ammonia epholileyo kufuneka ibe ngaphantsi kunobushushu obuphuphumayo.
Apho ifreon isetyenziswa njengesikhenkcisi, indawo yokukhenkca ye-oyile yokuthambisa inokuba ngaphezulu kancinane kunobushushu obuphuphumayo.
·Khetha i-oyile yokuthambisa ngokweemeko zokusebenza zesikhenkcisi.
