Ioyile esetyenziselwa ukuthambisa iindawo ezihambayo kwi-compressor yefriji ibizwa ngokuba yi-oyile yefriji, eyaziwa ngokuba yi-oyile yokuthambisa. Ngokwemigangatho yoMphathiswa wezoShishino lwePetrochemical, kukho iintlobo ezintlanu zeeoyile zefriji eziveliswa eTshayina, ezizezi, iNombolo 13, iNombolo 18, iNombolo 25, iNombolo 30 kunye neNombolo 40 yomgangatho weshishini. Phakathi kwazo, ii-lubricants ze-compressor yefriji ezisetyenziswa kakhulu yiNombolo 13, iNombolo 18 kunye neNombolo 25, ii-compressors ze-R12 ngokubanzi zikhetha iNombolo 18, ii-compressors ze-R22 ngokubanzi zikhetha iNombolo 25.
Kwicompressor, ioyile yokukhenkcisa ikakhulu ilubrication, sealing, cooling kunye nolawulo lwamandla olunemisebenzi emine.
(1) Ukuthambisa
Ioyile yefrijini xa kusetyenzwa i-compressor lubrication, ukuze kuncitshiswe izinga lokungqubana kunye nokuguga komsebenzi we-compressor, ngaloo ndlela kwandiswe ubomi benkonzo ye-compressor.
(2) Ukutywina
Ioyile yefriji idlala indima yokutywina kwicompressor, ukuze i-piston yecompressor kunye nomphezulu wesilinda, phakathi kweebheringi ezijikelezayo ukuze kufezekiswe isiphumo sokutywina, ukuze kuthintelwe ukuvuza kwefriji.
(3) Ukuphola
Xa ithambisiwe phakathi kweendawo ezishukumayo zecompressor, ioyile yefriji inokususa ubushushu obuveliswa ngexesha lokusebenza, ukuze iindawo ezishukumayo zigcine ubushushu obuphantsi, ngaloo ndlela kuphuculwe ukusebenza kakuhle nokuthembeka kwecompressor.
(4) Ulawulo lwamandla
Kwi-compressor yefriji enendlela yokulawula amandla, ungasebenzisa uxinzelelo lweoyile yeoyile yefriji njengamandla oomatshini bokulawula amandla.
Okokuqala, zithini iimfuno zezixhobo zokukhenkcisa kwioyile yokukhenkcisa
Ngenxa yokusetyenziswa kwezihlandlo ezahlukeneyo kunye neefriji, izixhobo zokukhenkcisa xa ukhetha ioyile yokukhenkcisa azifani. Iimfuneko zeoyile yokukhenkcisa zinemiba elandelayo:
1, ukuxinana
Iimpawu zeoyile ye-viscosity yeoyile yefriji ziyiparameter ebalulekileyo, ukusetyenziswa kweefriji ezahlukeneyo ukukhetha ioyile yefriji eyahlukileyo ngokufanelekileyo. Ukuba i-viscosity yeoyile yefriji inkulu kakhulu, amandla okuxinana koomatshini, ubushushu bokuxinana kunye ne-torque yokuqala ayanda. Ngokwahlukileyo koko, ukuba i-viscosity incinci kakhulu, iya kwenza intshukumo phakathi kwamalungu ingakwazi ukwenza ifilimu yeoyile efunekayo, ukuze ingafikeleli kwisiphumo sokuthambisa kunye nokuphola esifunekayo.
2, indawo yokufuma
Inqanaba lokuxinana kweoyile yokukhenkcisa kukuba xa ubushushu buncitshisiwe ukuya kwixabiso elithile, ioyile yokukhenkcisa iqale ukurhawuzelela iparafini, ukuze ioyile yokuthambisa ibe liqondo lokuxinana. Izixhobo zokukhenkcisa ezisetyenziswa kwioyile yokukhenkcisa kufuneka zibe ngaphantsi kobushushu bokufuma kwefriji, kungenjalo ziya kubangela ukuvaleka kwevalvu ye-throttle okanye zichaphazele ukusebenza kokudluliselwa kobushushu.
3, indawo yokuqinisa
Ioyile yefriji kwiimeko zovavanyo zokuphola ukuze kumiswe ukuhamba kobushushu okwaziwa ngokuba yindawo yokuqandisa. Izixhobo zefriji ezisetyenziswa kwindawo yokuqandisa yeoyile yefriji kufuneka zibe sezantsi kangangoko (njenge-compressor ye-R22, ioyile yefriji kufuneka ibe ngaphantsi kwe--55℃), kungenjalo kuya kuchaphazela ukuhamba kwefriji, kwandise ukumelana nokuhamba, nto leyo ekhokelela ekudlulisweni kobushushu okungalunganga.
4, indawo yokukhanya
I-flash point ye-refrigerant oil yeyona iphantsi kakhulu apho i-lubricant ifudunyezwa khona ukuya kuthi ga kwinqanaba apho umphunga wayo uvutha khona xa udibana nelangatye. Izixhobo ze-refrigeration oil ezisetyenziswa kwi-flash point ye-freezer oil kufuneka zibe phezulu kune-exhaust ye-exhaust eyi-15 ~ 30.℃okanye ngaphezulu, ukuze kungabangela ukutsha kunye nokucolwa kweoyile yokuthambisa.
5, uzinzo lweekhemikhali kunye nokumelana neoksijini
Ukwakheka kweekhemikhali zeoyile yokuthambisa ecocekileyo kuzinzile, akuyo-oxidation, akuyi kuyidla intsimbi. Nangona kunjalo, xa i-lubricant ine-refrigerant okanye amanzi aya kuvelisa ukugqwala, i-lubricant oxidation iya kuvelisa i-asidi, ukugqwala kwesinyithi. Xa i-lubricant kumaqondo obushushu aphezulu, kuya kubakho i-coke, ukuba le nto inamathele kwi-valve plate, iya kuchaphazela ukusebenza okuqhelekileyo kwe-valve plate, kwangaxeshanye iya kubangela ukuvaleka kwe-filter kunye ne-throttle valve. Ke ngoko, kufuneka ikhethwe ngozinzo lweekhemikhali kunye nokumelana ne-oxidation zi-lubricant ezilungileyo ze-freezer.
6, ukufuma kunye nokungcola koomatshini
Ukuba ioyile yokuthambisa inamanzi, iya kwenza utshintsho olukhulu kwiikhemikhali kwioyile, ukuze ioyile yonakale, nto leyo ebangela ukubola kwesinyithi, kodwa nakwivalvu yokuthambisa okanye ivalvu yokwandisa ibangele “ukuvaleka komkhenkce”. Ioyile yokuthambisa iqulethe ukungcola koomatshini, iya kwenza kube nzima ukuguguleka komphezulu weendawo ezihambayo, kwaye kungekudala ivale isihluzi kunye nevalvu yokuthambisa okanye ivalvu yokwandisa, ngoko ke ioyile yokuthambisa efrijini akufuneki ibe nokungcola koomatshini.
7, ukusebenza kwe-insulation
Kwifriji evaliweyo nevalekileyo ngokupheleleyo, ioyile yokuthambisa eqandisayo kunye nefriji zisebenza ngqo kunye nee-motor windings kunye noqhagamshelwano lwesiphelo, ngaloo ndlela ifuna i-lubricant ineempawu ezilungileyo zokuthintela ubushushu kunye ne-voltage ephezulu yokuqhekeka. Ukusebenza kwe-oyile yokuthambisa ecocekileyo kulungile, kodwa iqulethe amanzi, ukungcola kunye nothuli, ukusebenza kwayo kwe-insulation kuya kuncipha, iimfuno eziqhelekileyo ze-voltage ye-2.5KV yokuqhekeka kwe-oyile yefriji ye-2.5KV nangaphezulu.
8, ngenxa yeempawu zeentlobo ezahlukeneyo zeefriji zahlukile, ubushushu bokusebenza kwenkqubo yokukhenkcisa buyahluka kakhulu, igrisi yefriji ngokubanzi inokukhethwa ngolu hlobo: iimeko zesantya esiphantsi, ubushushu obuphantsi bezixhobo zokukhenkcisa zinokukhethwa njenge-viscosity, indawo yokukhenkcisa ephantsi yezithambiso; kunye neemeko zesantya esiphezulu okanye zomoya-moya zezixhobo zokukhenkcisa kufuneka zikhethwe njenge-viscosity, indawo yokukhenkcisa yezithambiso eziphezulu.
二、 Iinkcukacha zokusetyenziswa kweoyile yokuqandisa yecompressor
1. Inkqubo yokupholisa umoya ye-HFC-134a (R-134a) kunye nezixhobo ze-HFC-134a (R-134a) zinokusebenzisa kuphela ioyile yefriji echaziweyo. Ioyile yefriji engalawulwayo iya kuchaphazela isiphumo sokuthambisa secompressor, kwaye ukuxutywa kweentlobo ezahlukeneyo zeoyile yefriji kunokubangela i-oxidation kunye nokungaphumeleli kweoyile yefriji, nto leyo enokubangela ukungaphumeleli kwecompressor.
2. I-HFC-134a (R-134a) ichaza ukuba ioyile yokukhenkcisa inokufunxa umswakama emoyeni ngokukhawuleza. Nceda ulandele la manyathelo alandelayo:
(1) Xa kususwa izixhobo zokukhenkcisa kwizixhobo zokukhenkcisa, ezo zinto mazigqunywe (zivalwe) ngokukhawuleza ukuze kuncitshiswe ukungena komswakama emoyeni.
(2) Xa ufaka izinto zokukhenkcisa, musa ukususa (okanye ukuvula) isigqubuthelo sezinto ngaphambi kokuba uzidibanise. Nceda uqhagamshele izinto zesekethe yokukhenkcisa ngokukhawuleza ukuze unciphise ukungena komswakama emoyeni.
(3) Zizithambiso ezichaziweyo kuphela ezigcinwe kwizikhongozeli ezivaliweyo ezinokusetyenziswa. Emva kokusetyenziswa, nceda uvale ngoko nangoko isikhongozeli sesithambiso. Ukuba isithambiso asivalwanga kakuhle, asinakuphinda sisetyenziswe emva kokuba singene kumswakama.
3. Musa ukusebenzisa ioyile yefriji eyonakeleyo neyomileyo, kuba iya kuchaphazela ukusebenza okuqhelekileyo kwecompressor.
4. Le nkqubo kufuneka yongeze ioyile yefriji ngokwemilinganiselo emiselweyo. Ukuba ioyile yefriji iphantsi kakhulu, iya kuchaphazela ukuthambisa kwecompressor. Ukongeza ioyile yefriji eninzi kakhulu kuya kuchaphazela namandla okupholisa enkqubo yomoya opholileyo.
5. Xa ufaka i-refrigerant, kufuneka kongezwe ioyile ye-refrigerant kuqala, uze wongeze i-refrigerant
