Isithwathwa esikhumulweni somoya esibuyayo se-compressor yokugcina abandayo kuyinto evamile kakhulu ohlelweni lwesiqandisi.Ngokuvamile, ngeke kudale inkinga yesistimu ngokushesha, futhi isithwathwa esincane ngokuvamile asibhekwana nakho.Uma isimo se-frost sibi kakhulu, khona-ke isidingo sokuqala sokususa imbangela yesithwathwa
Okokuqala, i-compressor air return port iqhwa
Isithwathwa endaweni yokungenisa umoya ebuyayo sibonisa ukuthi izinga lokushisa lomoya elibuyayo le-compressor liphansi kakhulu.Khona-ke yini ezokwenza ukuthi izinga lokushisa lomoya elibuyayo le-compressor libe liphansi kakhulu?
Ubuningi obufanayo besiqandisi, uma umthamo nokucindezela kushintsha, izinga lokushisa lizoba nokusebenza okuhlukile.Uma izinga lokushisa lokubuya kwe-compressor liphansi, ngokuvamile lizobonisa ukucindezela kwegesi okubuyayo okuphansi kanye nevolumu yesiqandisi ephezulu yevolumu efanayo ngesikhathi esifanayo.Umsuka walesi simo ukuthi isiqandisi esigeleza ku-evaporator asikwazi ukumunca ngokugcwele ukushisa okudingwa ukunwetshwa kwaso kunani lokushisa elinqunywe kusengaphambili.
Kunezimbangela ezimbili zale nkinga:
- I-throttle liquid refrigerant supply ijwayelekile, kodwa i-evaporator ayikwazi ukumunca ukushisa ngokujwayelekile;
- ukumuncwa kokushisa kwe-evaporator kusebenza ngokujwayelekile, kodwa ukunikezwa kwesiqandisi se-throttle kuningi kakhulu, okungukuthi, ukugeleza kwesiqandisi kuningi kakhulu, ngokuvamile siyaqonda ukuthi isiqandisi siningi.
Okwesibili, ngenxa yokuncipha kwe-fluorine okubangelwa isithwathwa se-compressor esibuyisela igesi
1.ngoba ukugeleza kwesiqandisi kuncane kakhulu
Ukunwetshwa kwesiqandisi okuncane kakhulu ngeke kusebenzise yonke indawo ye-evaporator, futhi kuzokwakha izinga lokushisa eliphansi kuphela ku-evaporator.Kwezinye izindawo, ngenxa yenani elincane lesiqandisi kanye nokwanda okusheshayo, izinga lokushisa lendawo liphansi kakhulu, futhi kuvela i-evaporator frost phenomenon.
Ngemuva kwesithwathwa sendawo, ngenxa yokwakhiwa kwesendlalelo sokushisa ukushisa ebusweni be-evaporator kanye nokudluliswa kokushisa okuphansi kule ndawo, ukunwetshwa kwesiqandisi kudluliselwa kwezinye izindawo, futhi kancane kancane i-evaporator yonke i-frosting noma i-icing phenomenon, yonke i-evaporator. kwakheka isendlalelo sokuvikela ukushisa, ngakho-ke ukunwetshwa kuzosakazeka epayipini lokubuya le-compressor eliholela ekubuyiseleni igesi ye-compressor.
2.ngenxa yobuncane besiqandisi
Ingcindezi ephansi yokuhwamuka ku-evaporator iholela ekuhwamukeni okuphansi kwezinga lokushisa, okuzoholela kancane kancane ekujikeni ku-evaporator ukuze kwakhiwe ungqimba lwe-heat insulation, futhi kudlulisele iphuzu lokunweba kwigesi yokubuyisela i-compressor, okuholela ekubuyiseleni kwesithwathwa se-compressor.
Ingcindezi ephansi yokuhwamuka ku-evaporator iholela ekuhwamukeni okuphansi kwezinga lokushisa, okuzoholela kancane kancane ekujikeni ku-evaporator ukuze kwakhiwe ungqimba lwe-heat insulation, futhi kudlulisele iphuzu lokunweba kwigesi yokubuyisela i-compressor, okuholela ekubuyiseleni kwesithwathwa se-compressor.
Amaphuzu amabili angenhla azokhombisa i-evaporator frosting ngaphambi kokuba i-compressor ibuyisele isithwathwa somoya.
Eqinisweni, ezimweni eziningi ze-frost phenomenon, inqobo nje uma ukulungiswa kwe-valve ye-bypass yegesi eshisayo.Indlela eqondile ukuvula isembozo esingemuva esingemuva se-valve yegesi eshisayo, bese usebenzisa isikrufu esingu-No.8 hex ukuze uguqule inadi elilungisayo libe ngaphakathi ngokwewashi.Inqubo yokulungisa ayisheshi kakhulu.Ngokuvamile, izomiswa ngemva kwesigamu sokujika, futhi isistimu izosebenza isikhathi esithile ukuze ibone isimo sesithwathwa ngaphambi kokunquma ukuthi izoqhubeka yini nokulungisa.Uma ukusebenza kuzinzile futhi isenzakalo se-frosting se-compressor siyanyamalala, qinisa isembozo sokugcina.
Okwesithathu i-cylinder head frosting (i-serious crankcase frosting)
I-cylinder head frosting ibangelwa inani elikhulu lesitimu esimanzi noma i-compressor yokumunca isiqandisi.Izizathu eziyinhloko zalokhu yilezi:
- Ukuvulwa kwe-valve yokwandisa okushisayo kukhulu kakhulu, futhi ukufakwa kwephakheji yokuzwa izinga lokushisa akulungile noma kulungiswe ngokukhululekile, ukuze izinga lokushisa elizwakalayo liphezulu kakhulu futhi i-spool ivuleke ngokungavamile.
I-valve yokwandisa okushisayo isebenzisa ukushisa okuphezulu endaweni yokukhipha umhwamuko njengesignali yempendulo ukuze kukhiqizwe isignali yokuchezuka ngemva kokuyiqhathanisa nenani lokushisa okuphezulu elinikeziwe ukuze kulungiswe ukugeleza kwesiqandisi ku-evaporator.Iwumlawuli oqondile osebenza ngokulinganayo, ohlanganisa isidlulisi, isilawuli kanye ne-actuator.
Ngokuya ngezindlela ezihlukene zokulinganisa, ama-valve okwandisa ukushisa angahlukaniswa abe:
I-valve yokwandisa okushisayo yangaphakathi;
I-valve yangaphandle yokwandisa ukushisa okushisayo.
I-valve yokunweba eshisayo ivulwa kakhulu, iphakheji yokuzwa izinga lokushisa ifakwe ngokungalungile noma ilungiswe ngokukhululekile, ukuze izinga lokushisa elizwakalayo libe phezulu kakhulu futhi i-spool ivuleke ngendlela engavamile, okwenza inani elikhulu le-steam emanzi limunce ku-compressor, okuholela ekutheni isithwathwa ekhanda lesilinda.
I-valve yokwandisa okushisayo ivulwe kakhulu kakhulu, iphakheji yokuzwa izinga lokushisa ifakwe ngokungalungile noma ilungiswe ngokukhululekile, ukuze izinga lokushisa elizwakalayo liphakeme kakhulu, i-spool ivuleke ngendlela engavamile, okuholela ekutheni kufakwe umusi omningi omanzi ku-compressor, futhi Ikhanda le-cylinder liqhwa.
- Lapho i-valve ye-solenoid ewuketshezi ivuza noma ima, ivalve yokunweba ayivaleki ngokuqinile
Inani elikhulu loketshezi oluyisiqandisi linqwabelene ku-evaporator ngaphambi kokuqala.Lesi simo futhi kulula ukubangela i-compressor liquid hit!
- Isiqandisi esiningi kakhulu ohlelweni
Izinga le-liquid ku-condenser liphakeme, indawo yokudlulisa ukushisa encishisiwe iyancishiswa, ukuze ingcindezi yokuqina ikhule, okungukuthi, ingcindezi ngaphambi kokuba i-valve yokwandisa inyuke, umthamo wesiqandisi ku-evaporator uyanda, isiqandisi esiwuketshezi asikwazi ukuhwamuka ngokuphelele. ku-evaporator, ngakho-ke i-compressor idonsa umusi omanzi, izinwele ze-cylinder ziyabanda noma ziqhwa, futhi zingabangela "ukushaywa kwe-liquid", futhi ingcindezi yokuhwamuka izoba phezulu.
