Uwoyela osetshenziselwa ukugcoba izingxenye ezihambayo ku-compressor yesiqandisi ubizwa ngokuthi uwoyela wesiqandisi, owaziwa nangokuthi uwoyela wokugcoba. Ngokwezindinganiso zoMnyango Wezimboni Ze-Petrochemical, kunezinhlobo ezinhlanu zamafutha esiqandisi akhiqizwa eShayina, okungukuthi, uNombolo 13, uNombolo 18, uNombolo 25, uNombolo 30 kanye noNombolo 40 wezinga lebhizinisi. Phakathi kwazo, amafutha esiqandisi esiqandisi asetshenziswa kakhulu yiNombolo 13, uNombolo 18 kanye noNombolo 25, ama-compressor e-R12 ngokuvamile akhetha uNombolo 18, ama-compressor e-R22 ngokuvamile akhetha uNombolo 25.
Ku-compressor, uwoyela oqandisiwe uvame ukugcotshwa, ukuvalwa, ukupholisa kanye nokulawulwa kwamandla kwezindima ezine.
(1) Ukuthambisa
Uwoyela wefriji ekusebenzeni kokuthambisa kwe-compressor, ukuze kuncishiswe izinga lokungqubuzana kanye nokuguguleka kokusebenza kwe-compressor, ngaleyo ndlela kwandiswe impilo yenkonzo ye-compressor.
(2) Ukuvala
Uwoyela wefriji udlala indima yokuvala ku-compressor, ukuze i-piston ye-compressor kanye nobuso besilinda, phakathi kwama-bearings ajikelezayo kufezwe umphumela wokuvala, ukuze kuvinjelwe ukuvuza kwe-refrigerant.
(3) Ukupholisa
Uma igcotshwa phakathi kwezingxenye ezihambayo ze-compressor, uwoyela we-refrigerant ungasusa ukushisa okukhiqizwa ngesikhathi senqubo yokusebenza, ukuze izingxenye ezihambayo zigcine izinga lokushisa eliphansi, ngaleyo ndlela kuthuthukiswe ukusebenza kahle nokuthembeka kwe-compressor.
(4) Ukulawulwa kwamandla
Kwi-compressor yesiqandisi enendlela yokulawula amandla, ingasebenzisa ingcindezi kawoyela kawoyela wesiqandisi njengamandla emishini yokulawula amandla.
Okokuqala, yiziphi izidingo zemishini yokuqandisa uwoyela wokuqandisa
Ngenxa yokusetshenziswa kwezikhathi ezahlukene kanye neziqandisi, imishini yokuqandisa lapho ukhetha uwoyela wokuqandisa ayifani. Izidingo zamafutha okuqandisa zinezici ezilandelayo:
1, ukujiya
Izici zikawoyela we-viscosity kawoyela wefriji ziyipharamitha ebalulekile, ukusetshenziswa kwama-refrigerant ahlukene ukukhetha uwoyela wefriji ohlukile ngokufanele. Uma i-viscosity kawoyela wefriji inkulu kakhulu, amandla okungqubuzana komshini, ukushisa kokungqubuzana kanye ne-torque yokuqala kuyanda. Ngokuphambene nalokho, uma i-viscosity incane kakhulu, izokwenza ukunyakaza phakathi kwezingxenye kungabi yikho okwakha ifilimu kawoyela edingekayo, ukuze kungafinyelelwa umphumela wokugcotshwa nokupholisa ofiselekayo.
2, iphuzu lokugcwala
Iphuzu lokudungeka kwamafutha esiqandisini ukuthi izinga lokushisa lehliswa libe yinani elithile, uwoyela wesiqandisini waqala ukukhukhumeza i-parafini, ukuze uwoyela wokugcoba ube yizinga lokushisa lokudungeka. Imishini yesiqandisini esetshenziswa kumafutha esiqandisini, iphuzu lokudungeka kwamafutha kufanele ibe ngaphansi kunezinga lokushisa lokuhwamuka kwe-refrigerant, ngaphandle kwalokho izobangela ukuvaleka kwe-throttle valve noma ithinte ukusebenza kokudlulisa ukushisa.
3, iphuzu lokuqina
Uwoyela wefriji ezimweni zokuhlola zokupholisa ukuze umise ukugeleza kwezinga lokushisa elaziwa ngokuthi indawo yokuqandisa. Imishini yesiqandisi esetshenziswa endaweni yokuqandisa uwoyela wefriji kufanele ibe phansi ngangokunokwenzeka (njenge-compressor ye-R22, uwoyela wefriji kufanele ube ngaphansi kuka--55℃), ngaphandle kwalokho kuzothinta ukugeleza kwe-refrigerant, kwandise ukumelana nokugeleza, okuholela ekudlulisweni kokushisa okubi.
4, iphuzu elikhanyayo
Iphuzu lokusheshisa likawoyela wefriji yizinga lokushisa eliphansi kakhulu lapho igrisi ishiswa khona kuze kufike lapho umhwamuko wayo uvutha khona uma uthinta ilangabi. Imishini yesiqandisi esetshenziswa endaweni yokusheshisa kawoyela wefriji kumele ibe ngaphezu kwezinga lokushisa lokukhipha ugesi elingu-15 ~ 30.℃noma ngaphezulu, ukuze kungabangeli ukusha nokubiliswa kwamafutha okugcoba.
5, ukuzinza kwamakhemikhali kanye nokumelana nomoya-mpilo
Ukwakheka kwamakhemikhali kawoyela wokugcoba okumsulwa kuzinzile, hhayi ukubola, ngeke kugqwale insimbi. Kodwa-ke, uma i-lubricant iqukethe i-refrigerant noma amanzi azokhiqiza ukugqwala, ukubola kwe-lubricant kuzokhiqiza i-asidi, ukugqwala kwensimbi. Lapho i-lubricant emazingeni okushisa aphezulu, kuzoba ne-coke, uma le nto inamathele epuletini le-valve, izothinta ukusebenza okuvamile kwepuleti le-valve, ngasikhathi sinye kuzobangela ukuvaleka kwe-valve yesihlungi ne-throttle. Ngakho-ke, kumele kukhethwe ngokuqina kwamakhemikhali kanye nokumelana nokubola, i-lubricant enhle yefriji.
6, umswakama kanye nokungcola kwemishini
Uma uwoyela wokugcoba uqukethe amanzi, kuzokwandisa izinguquko zamakhemikhali ku-oyela, ukuze uwoyela ubole, okuholela ekugqwaleni kwensimbi, kodwa futhi ku-valve ye-throttle noma i-valve yokwandisa kubangele "ukuvinjelwa kweqhwa". Uwoyela wokugcoba uqukethe ukungcola komshini, uzokhulisa ukuguguleka kobuso bokungqubuzana kwezingxenye ezihambayo, futhi ngokushesha uvimbele i-filter ne-throttle valve noma i-valve yokwandisa, ngakho uwoyela wokugcoba wefriji akufanele ube nokungcola komshini.
7, ukusebenza kokushisa
Efrijini elivalwe kancane futhi elivalwe ngokuphelele, uwoyela wokugcoba oqandisayo kanye ne-refrigerant kuyizimbobo eziqondile nezihambayo kanye nokuxhumana kwe-terminal, ngaleyo ndlela kudinga ukuthi i-lubricant ibe nezakhiwo ezinhle zokuvikela kanye ne-voltage ephezulu yokuqhekeka. Ukusebenza kahle kokuvikela uwoyela wokugcoba ohlanzekile kuhle, kodwa kuqukethe amanzi, ukungcola kanye nothuli, ukusebenza kwayo kokuvikela kuzoncishiswa, izidingo ezijwayelekile ze-voltage yokuqhekeka kwamafutha okugcoba efrijini engu-2.5KV noma ngaphezulu.
8, ngenxa yezici zezinhlobo ezahlukene zama-refrigerant zihlukile, izinga lokushisa lokusebenza kohlelo lokuqandisa liyahlukahluka kakhulu, i-freezer lubricant ngokuvamile ingakhethwa ngale ndlela: izimo zesivinini esiphansi, zokushisa okuphansi kwemishini yokuqandisa zingakhethwa njenge-viscosity, iphuzu eliphansi lokuqandisa lama-lubricant; kanye nezimo zesivinini esiphezulu noma zokupholisa umoya zemishini yokuqandisa kufanele zikhethwe njenge-viscosity, iphuzu lokuqandisa lama-lubricant aphezulu.
二、 Imininingwane yokusetshenziswa kwamafutha okupholisa e-compressor
1. Uhlelo lokupholisa umoya lwe-HFC-134a (R-134a) kanye nezingxenye ze-HFC-134a (R-134a) zingasebenzisa kuphela uwoyela oqandisiwe ochaziwe. Uwoyela oqandisiwe ongalawulwa uzothinta umphumela wokugcoba we-compressor, futhi ukuxuba amazinga ahlukene kawoyela oqandisiwe kungabangela ukubola kanye nokwehluleka kukawoyela oqandisiwe, okungaholela ekwehlulekeni kwe-compressor.
2. I-HFC-134a (R-134a) ibeka ukuthi uwoyela wokuqandisa ungamunca umswakama emoyeni ngokushesha. Sicela ulandele lezi zinyathelo ezilandelayo:
(1) Uma uhlukanisa izingxenye zesiqandisi emishinini yesiqandisi, izingxenye kufanele zimbozwe (zivalwe) ngokushesha okukhulu ukuze kuncishiswe ukungena komswakama emoyeni.
(2) Uma ufaka izingxenye zesiqandisi, ungasusi (noma uvule) isembozo sezingxenye ngaphambi kokuzixhuma. Sicela uxhume izingxenye zesikethi sesiqandisi ngokushesha okukhulu ukuze unciphise ukungena komswakama emoyeni.
(3) Kungasetshenziswa kuphela amafutha okugcoba agcinwe ezitsheni ezivaliwe. Ngemva kokusebenzisa, sicela uvale ngokushesha isitsha sokugcoba. Uma amafutha okugcoba engavaliwe kahle, awakwazi ukusetshenziswa futhi ngemva kokungena komswakama.
3. Ungasebenzisi uwoyela wefriji owonakele futhi onamafu, njengoba uzothinta ukusebenza okuvamile kwe-compressor.
4. Uhlelo kufanele lufake uwoyela we-refrigerant ngokwesilinganiso esinqunyiwe. Uma uwoyela we-refrigerant uphansi kakhulu, uzothinta ukugcotshwa kwe-compressor. Ukwengeza uwoyela we-refrigerant omningi kakhulu kuzothinta namandla okupholisa uhlelo lokupholisa umoya.
5. Uma ufaka i-refrigerant, kufanele kufakwe uwoyela we-refrigerant kuqala, bese kufakwa i-refrigerant
