Ioli engumkhenkce embi yonakalise icompressor

1.I-Viscosity yeoli engumkhenkce: I-oyile engumkhenkce ine-viscosity ethile yokugcina i-friction surface yeendawo ezihambayo kwindawo efanelekileyo yokuthambisa, ukuze ithathe inxalenye yobushushu obuvela kwi-compressor kwaye idlale indima yokutywina.

I-oyile isebenza kumaqondo obushushu amabini: Ukushisa kwe-valve ye-compressor kunokuba ngaphezu kwe-100 degrees, kunye ne-valve yokwandisa, ukushisa kwe-evaporator kuya kuba ngaphantsi kwama-degrees angama-40. ukugqoka kunye nengxolo ye-compressor bearing kunye ne-cylinder, kwaye ngexesha elifanayo ukunciphisa umphumo wokupholisa kunye nokunciphisa ubomi benkonzo ye-compressor.Nangeemeko ezinzima, i-compressor inokutshiswa.

I-2.Pour point of oil frozen: I-Pour point nayo isalathisi esinokukhokelela kumatshini ovuthayo.Ukushisa okusebenzayo kwe-compressor kunoluhlu olubanzi lokuhluka.Ngoko ke, ukuze kuqinisekiswe ukuba umsebenzi wokuthambisa unokwenziwa ngokuqhelekileyo, ngokuqhelekileyo kufuneka ukuba ugcine umsebenzi omhle kwiqondo lokushisa eliphantsi.Ngoko ke, indawo yokugalela kufuneka ibe ngaphantsi kweqondo lokushisa, kwaye i-viscosity kunye neqondo lokushisa kufuneka libe lihle, ukuba ioli engumkhenkce ingabuyela kakuhle kwicompressor evela kwi-evaporator kwindawo yobushushu obuphantsi.Ukuba indawo yokugalela yeoli engumkhenkce iphezulu kakhulu, Kuya kubangela ukuba i-oyile ibuye ngokucothayo ukuba umatshini wesiganeko esilula utshiswe.

3. Inqaku le-Flash yeoli engumkhenkce: Kukho ingozi yokuba i-flash point ye-oyile engumkhenkce iphantsi kakhulu.Ngenxa ye-volatility ephezulu, i-flash point ephantsi iya kwandisa inani leoli kumjikelezo wefriji. yongeza kwiindleko.Okona kubi kakhulu kukunyuka komngcipheko wokutsha ngexesha lokunyanzeliswa kunye nokufudumala, okudinga ukuba i-flash point yeoli efrijiweyo ingaphezulu kwama-30 degrees ngaphezu kokushisa kwefriji.

I-4.Uzinzo lweChemical: Ukwakhiwa kweekhemikhali zeoli ecocekileyo efriziwe zizinzile, ayifaki i-oxidize, ayiyi kutshabalalisa isinyithi.Xa i-oyile i-oxidizes, iya kuvelisa i-asidi kunye ne-corrode metal.Xa ioli efriziwe ikwiqondo lokushisa eliphezulu, kuya kubakho i-coke kunye nomgubo, ukuba le nto ingena kwi-filter kunye ne-valve ye-throttle ebangelwa ngokulula. ifilimu yokugquma.Loo matshini ukwenzeka lula utshiswe.

5. Ukungcola okugqithisileyo komatshini kunye nomxholo wokufuma: Ukungcola okugqithisileyo komatshini kunye nomxholo wokufuma: ukuba i-oyile ekhenkcezisiweyo inomswakama, iya kuyenza ibe mandundu utshintsho lweekhemikhali zeoyile, ibangele ukuwohloka kweoyile, ibangele ukubola kwintsimbi, kwaye ibangele "i-ice block" kwi-throttle. okanye i-valve yokwandisa.I-oyile yokuthambisa iqulethe ukungcola komatshini, okuya kwandisa ukugquma kwe-friction surface yeendawo ezihambayo kwaye kubangele umonakalo kwi-compressor.

6.. Isiqulatho esiphezulu separafini:Xa iqondo lobushushu elisebenzayo lecompressor lehla laya kutsho kwixabiso elithile, iparafini iqalisa ukohlukana ne-oyile engumkhenkce, nto leyo eyenza ibhulukhwe.

I-oyile ekhenkcezayo ikhupha iparafini kwaye iqokelelane kwi-throttle ukuvala i-throttle okanye inokuqokelela kumphezulu wokudlulisa ubushushu be-evaporator, echaphazela ukusebenza kokudluliselwa kobushushu.

Indlela yokuxelela ukuba ioli efriziweyo embi

Umgangatho weoyile engumkhenkce unokujongwa ngumbala weoyile. Umbala oqhelekileyo weoyile yeminerali engumkhenkce ubonakala elubala kwaye utyheli kancinci, ukuba kukho amafu okanye umbala unzulu kakhulu kwioyile, ukungcola kunye nomxholo weparafini uphezulu. umbala oqhelekileyo we-ester synthetic oyile engumkhenkce yibhanti ecacileyo etyheli, imnyama kancinci kuneoyile yezimbiwa.Ukuphakama kwe-kinematic viscosity kukuba, umbala ubumnyama.Xa i-viscosity ifikelela kwi-220mPa. Umbala uqaqambileyo ophuzi kunye nobomvu obomvu.

Singathatha iphepha elicocekileyo lephepha elimhlophe, sikhuphe i-oyile efriziwe, siyilahle kwiphepha elimhlophe, kwaye emva koko sijonge umbala weoli. I-oyile ikumgangatho ongcono, Ukuba amachaphaza amnyama okanye izangqa zifunyenwe kwiphepha elimhlophe, ioyile engumkhenkce yonakele okanye iphantsi ioyile ekhenkcezisiweyo.
