Uwoyela omubi oyiqhwa wonakalise i-compressor

1.I-Viscosity yamafutha aqandisiwe: Uwoyela oyiqhwa une-viscosity ethile yokugcina i-face friction yezingxenye ezihambayo esimweni esihle sokuthambisa, ukuze ikwazi ukuthatha ingxenye yokushisa okuvela ku-compressor futhi idlale indima yokuvala.

Amafutha asebenza emazingeni okushisa amabili aphakeme kakhulu: Ukushisa kwe-valve ye-Compressor exhaust kungaba ngaphezu kwama-degree angu-100, futhi i-valve yokwandisa, izinga lokushisa le-evaporator liyoba liphansi -40 degrees. ukugqoka kanye nomsindo we-compressor bearing kanye ne-cylinder, futhi ngesikhathi esifanayo ukunciphisa umphumela wokupholisa futhi unciphise impilo yesevisi ye-compressor.Ngisho nasezimweni ezimbi kakhulu, i-compressor ingase ishiswe.

I-2.Pour iphuzu lamafutha afriziwe: Iphuzu lokuthela liphinde libe yinkomba engase iholele emshinini ovuthayo.Ukushisa okusebenzayo kwe-compressor kunezinhlobonhlobo ezihlukahlukene.Ngakho-ke, ukuze kuqinisekiswe ukuthi umsebenzi we-lubricant ungenziwa ngokujwayelekile, ngokuvamile kuyadingeka ukugcina umsebenzi omuhle ekushiseni okuphansi.Ngakho-ke, indawo yokuthululela kufanele ibe ngaphansi kwezinga lokushisa elibandayo, futhi i-viscosity nokushisa kufanele kube kuhle, ukuthi uwoyela oyiqhwa ungabuyela kahle ku-compressor usuka ku-evaporator endaweni yokushisa ephansi.Uma indawo yokuthela kawoyela oyiqhwa iphezulu kakhulu, Kuzokwenza ukuthi uwoyela ubuye kancane kakhulu lowo mshini owenzeka kalula ushisiwe.

3.Iphuzu le-Flash lamafutha afriziwe:Kukhona futhi ingozi yokuthi indawo ekhanyayo yamafutha afriziwe iphansi kakhulu.Ngenxa yokuguquguquka okukhulu, indawo ephansi ye-flash izokwandisa inani lamafutha emjikelezweni wesiqandisi.Ukwenyuka kokuguga nokudabuka. yengeza ezindlekweni.Okubi nakakhulu ukwanda kwengozi yokuvutha ngesikhathi sokucindezelwa nokushisa, okudinga ukuthi indawo ekhanyayo yamafutha afakwe esiqandisini ibe ngaphezu kwama-degree angu-30 ngaphezu kwezinga lokushisa elifakwe esiqandisini.

I-4.Ukuzinza kwamakhemikhali: Ukwakheka kwamakhemikhali amafutha ahlanzekile afriziwe azinzile, ayifaki i-oxidize, ayidli insimbi.Lapho amafutha e-oxidizes, azokhiqiza i-asidi nensimbi egqwalile.Lapho uwoyela oyiqhwa usemazingeni okushisa aphezulu, kuzoba ne-coke nempushana, uma le nto ingena kusihlungi kanye ne-throttle valve ebangelwa ukuvinjelwa kalula.Faka i-compressor futhi ngokunokwenzeka ubhoboze nge-motor. ifilimu ye-insulation.Lowo mshini owenzeka kalula washiswa.

5. Ukungcola okweqile kwemishini nomswakama: Ukungcola okweqile kwemishini kanye nomswakama: uma uwoyela oyiqhwa unomswakama, kuzokwandisa ukushintshwa kwamakhemikhali kawoyela, kubangele ukuwohloka kwamafutha, kubangele ukugqwala kwensimbi, futhi kubangele "iqhwa" lapho umphimbo. noma i-valve yokwandisa.Amafutha okugcoba aqukethe ukungcola kwemishini, okuzokwenza kube nzima ukuguga kwe-friction surface yezingxenye ezihambayo futhi kubangele umonakalo ku-compressor.

6..Okuqukethwe okuphezulu kukapharafini:Lapho izinga lokushisa elisebenzayo le-compressor lehla lifika enanini elithile, upharafini uqala ukuhlukana nowoyela oyiqhwa, okwenza kube nenkungu.

Amafutha aqandayo akhipha upharafini futhi anqwabelene ku-throttle ukuze avimbe i-throttle noma angase anqwabelene endaweni yokudlulisa ukushisa kwe-evaporator, kuthinte ukusebenza kokudlulisa ukushisa.

Ungasho kanjani ukuthi amafutha afriziwe amabi

Izinga lamafutha aqandisiwe lingahlulelwa ngombala wamafutha.Umbala ojwayelekile wamafutha amaminerali ayiqhwa usobala futhi ubaphuzi kancane, uma liguqubele noma umbala ujule kakhulu emafutheni, ukungcola nopharafini kuphezulu. umbala ojwayelekile kawoyela wokwenziwa we-ester oqandisiwe uyibhande elikhanyayo eliphuzi, limnyama kancane kunamafutha amaminerali.Ukuphakama kwe-kinematic viscosity, umbala umnyama.Uma i-viscosity ifinyelela ku-220mPa. Umbala uphuzi ngokukhazimulayo nobomvu obomvu.

Singathatha ishidi elihlanzekile lephepha elimhlophe, sikhiphe amafutha amancane afriziwe, siliphonsa ephepheni elimhlophe, bese sibuka umbala wamafutha .Uma amaconsi kawoyela elula futhi esabalaliswa ngokulinganayo, lokho kusho ukuthi iqhwa. uwoyela usezingeni elingcono, Uma amachashazi amnyama noma imibuthano etholakala ephepheni elimhlophe, uwoyela oyiqhwa uwohlokile noma ungaphansi kukawoyela oyiqhwa.
