Amafutha asetshenziselwa ukuthambisa izingxenye ezihambayo efrijini i-comprescer abizwa ngokuthi amafutha efriji, owaziwa nangokuthi uwoyela wokuthambisa. Ngokwezindinganiso zoMnyango Wezimboni ze-Petrochemical, kunamabanga amahlanu amafutha efriji akhiqizwa eChina, okungukuthi, No. 13, No. 18, No. 30 kwiZinga lamabhizinisi. Phakathi kwazo, okugciniwe okusetshenziswayo kwe-compressor okungu-3, no. 18 no-25 no-25, ama-comprescer angama-R12 ngokuvamile akhetha uNo. 18, ama-comprescer angu-R22 ngokuvamile akhetha uNo. 25.
Ku-compressor, uwoyela wefriji ikakhulukazi ukuthambisa, ukubeka uphawu, ukupholisa nokulawulwa kwamandla kwezindima ezine.
(1) lubrication
Amafutha efriji ekusebenzeni kwe-compressor lubrication, ukuze anciphise izinga lokuxabana nokugqoka nokudabula umsebenzi we-compressor, ngaleyo ndlela anwebe impilo yenkonzo ye-compressor.
(2) ukubekwa uphawu
Amafutha efriji adlala indima ebabayo ku-compressor, ukuze i-piston ye-compressors ne-cylinder ebusweni, phakathi kokujikeleza okujikelezayo ukufeza umphumela wokubopha, ukuze kuvinjelwe ukuvuza kokubekwa uphawu.
(3) ukupholisa
Lapho igcotshwe phakathi kwezingxenye ezinyakazayo ze-compressor, i-aulinda yamafutha esiqandisi ingasusa ukushisa okwenziwe ngesikhathi sokusebenza, ukuze izingxenye ezihambayo zilondoloze ukusebenza kwezinga eliphansi, ngaleyo ndlela zithuthukise ukusebenza kahle kanye nokwethembeka kwe-compressor.
(4) umthethonqubo wamandla
Ku-compressor yefriji nge-Energy Relagn Mechanism, ingasebenzisa ingcindezi kawoyela yamafutha esiqandisini njengamandla emishini yokulawulwa kwamandla.
Okokuqala, yiziphi izidingo zemishini yefriji ku-oyela wefriji
Ngenxa yokusetshenziswa kwezikhathi ezahlukahlukene kanye nesiqandisini, imishini yokuqandiselela ekukhetheni uwoyela wefriji akufani. Izidingo zokuthi uwoyela wefriji zinezici ezilandelayo:
I-1, viscosity
Isiqandisi samafutha we-viscosity viscosity izici zepharamitha ebalulekile, ukusetshenziswa kweziqandisini ezahlukahlukene ukukhetha uwoyela wefriji ahlukile ngokufanele. Uma i-viscosity kawoyela wefriji inkulu kakhulu, amandla okuphambana asebenza ngomshini, ukushisa kokuphazamisa kanye nokuqala kwe-torque kwanda. Ngokuphambene nalokho, uma i-viscosity incane kakhulu, izokwenza ukunyakaza phakathi kwezingxenye kungakwazi ukwakha ifilimu lamafutha adingekayo, ukuze kungafinyeleli ukuthathwa okufunwayo nokupholisa.
I-2, iphuzu le-turbidity
Iphuzu le-turbidity kawoyela wefriji izinga lokushisa lincishiswa libe yinani elithile, amafutha esiqandisi aqala ukunqamula uphalafini, ukuze uwoyela wokuthambisa uwoyela abe lokushisa elishubile. Imishini yefriji esetshenziselwa iphuzu lokuzithambisa kawoyela wefriji kufanele libe ngaphansi kwesilinganiso sokuhwamuka kwesiqandisi, uma kungenjalo kuzobangela ukuvalwa kwe-throttle valve noma kuthinte ukusebenza kokudlulisa ukushisa.
I-3, iphuzu lokuqina
Amafutha esiqandisi ezimweni zokuhlola zokupholisa ukumisa ukuhamba kwezinga lokushisa elaziwa ngokuthi yiphuzu eliyinhloko. Imishini yefriji esetshenziswe endaweni efrijini yamafutha eqandisi kufanele ibe phansi ngangokunokwenzeka (njengo-R22 compressor, uwoyela wefriji kufanele abe ngaphansi --55℃), ngaphandle kwalokho kuzothinta ukugeleza kwesiqandisi, ukukhulisa ukumelana kokugeleza, okuphumela ekudluliseleni okumpofu kokushisa.
4, I-Flash Point
Iphuzu le-Flash lamafutha esiqandisini liwukushisa okuphansi kakhulu lapho i-lubricant ifudunyezwa khona lapho kufika khona i-vapor yayo ithola ukuxhumana nelangabi. Imishini yefriji esetshenziswa eqoqweni le-Flash Flash le-Flash kumele libe liphakeme kunamazinga okushisa angu-15 ~ 30℃noma ngaphezulu, ukuze ungabingeli ukuhlanganiswa nokuhlanganiswa kwamafutha okuthambisa.
5, ukuqina kwamakhemikhali kanye nokumelana nomoya-mpilo
Ukwakheka okuhlanzekile kwamakhemikhali wamakhemikhali we-oyili kuyazinza, hhayi i-oxidation, ngeke kulwe insimbi. Kodwa-ke, lapho i-lubricant inesiqandisi noma amanzi izokhiqiza ukugqwala, i-lubrication oxidation izokhiqiza i-acid, ukubhujiswa kwensimbi. Lapho i-lubricant emazingeni okushisa aphezulu, kuzoba khona i-coke, uma lokhu okunamathiselwe epuletini ye-valve, kuzothinta ukusebenza okujwayelekile kwe-valve plate, ngasikhathi sinye kuzodala isihlungi kanye nokuvalwa kwe-throttle valve clogging. Ngakho-ke, kufanele kukhethwe ngokuqina kwamakhemikhali kanye nokumelana ne-oxidation kuyindlela enhle yokugcotshwa kwamahhala.
6, umswakama kanye nokungcola kwemishini
Uma uwoyela wokuthambisa aqukethe amanzi, azokhulisa ushintsho lwamakhemikhali emafutheni, ukuze uwohloke kawoyela, okubangelwa ukugcwala kwensimbi, kodwa futhi nase-throttle valve noma i-valve ye-threasion ukuze ubangeli "i-ice blockage". Amafutha okugcoba aqukethe ukungcola kwemishini, azokhulisa ubumbano lwezinkinga ezigqoke izingxenye ezinyakazayo, futhi maduze avimbele isihlungi kanye ne-throttle valve noma i-valve yokuthambisa, ngakho-ke i-freezer lubrating kawoyela akufanele ibe nokungcola kwemishini.
7, Ukusebenza kokufakelwa
E-Freezer evaliwe futhi evaliwe ngokuphelele, i-wrefing libsholo kawoyela futhi esiqandisini ngokuqondile kanye nama-motor windings kanye nokuxhumana okubulalayo, ngaleyo ndlela kudinga i-lubricant inezakhiwo ezinhle zokufaka kanye nogesi ophakeme. Ukusebenza okuhlanzekile kokufakwa ko-oyili wokufaka amafutha kulungile, kepha kuqukethe amanzi, ukungcola nothuli, ukusebenza kwalo kokufakelwa kuzoncishiswa, izidingo ezijwayelekile zokugcotshwa kwamafutha e-freezer uwoyela we-2.5KV noma ngaphezulu.
8, ngenxa yezimpawu zezinhlobo ezahlukahlukene zefriji ahlukile, izinga lokushisa lohlelo lwefriji liyahluka kakhulu, i-freezer lubrican ngokuvamile ingakhethwa ngale ndlela: Ijubane eliphansi, izimo zokushisa eziphansi zoMfashizi wefriji zikhethwe ukubonwa, iphuzu eliphansi lokugcotshwa; kanye nesivinini esikhulu noma izimo zomoya zomoya we-offtiger imishini kufanele zikhethwe ukubonakala, iphuzu lokufakelwa kwamafutha aphezulu.
二, Ukucaciswa kokusetshenziswa kwamafutha efrijorsorfrior ail
1 Amafutha wefriji alawulwayo azothinta umphumela wokuthambisa we-compressor, kanye nokuxutshwa kwamabanga ahlukene kawoyela wefriji kungadala i-oxidation nokwehluleka kowoyela wefriji, okungaholela ekwehlulekeni kwe-compressor.
2. I-HFC-134A (R-134A) ibeka ukuthi uwoyela wefriji ungamunca ngokushesha umswakama ovela emoyeni. Sicela ulandele izinyathelo ezilandelayo:
.
(2) Lapho ufaka izakhi zeqandisini, ungasusi (noma uvule) isembozo sezakhi ngaphambi kokuzixhuma. Sicela uxhume izingxenye ze-Reffider Circuit ngokushesha okukhulu ukunciphisa ukungena komswakama emoyeni.
(3) Ukuthambisa kuphela okucacisiwe okugcinwe ezitsheni ezivaliwe ezingasetshenziswa. Ngemuva kokusebenzisa, sicela ususe ngokushesha isitsha sokuthambisa. Uma i-lubricant ingavaliwe kahle, ayikwazi ukusetshenziswa futhi ngemuva kokungena umswakama.
3. Ungasebenzisi uwoyela okonakalisiwe futhi ovusiwe we-turmid, ngoba kuzothinta ukusebenza okujwayelekile kwe-compressor.
4. Uhlelo kufanele lungeze amafutha esiqandisini ngokuya ngomthamo obekiwe. Uma uwoyela wefriji uphansi kakhulu, kuzothinta ukuthambisa kwe-compressor. Ukungeza kakhulu uwoyela esiqandisini kuzothinta namandla okupholisa ohlelo lokupholisa umoya.
I-5. Lapho engeza esiqandisini, uwoyela wefriji kufanele wengezwe kuqala, bese kuthi isiqandisi kufanele sengezwe
