I-compressor ngumshini oyinkimbinkimbi osebenza ngejubane eliphezulu. Ukuqinisekisa ukuthambisa okwanele kwe-compressor crankshaft, ama-bearings, izinduku zokuxhuma, izinduku nezinye izingxenye ezinyakazayo kuyisidingo esiyisisekelo sokugcina ukusebenza okujwayelekile komshini. Ngalesi sizathu, abakhiqizi beCompressors badinga ukusetshenziswa kwamabanga acacisiwe okugcotshwa kwamafutha, futhi badinga ukuhlolwa okujwayelekile kwezinga lamafutha nombala wamafutha okugcoba. Kodwa-ke, ngenxa yobudedengu ekwakheni uhlelo lweqandisini, ukwakhiwa kanye nokulungiswa, ukuntuleka kwamafutha ku-compressor, ukukhwehlela kanye nokuwohloka kwamafutha, ukufuya okuyisiqandisi, nokusetshenziswa okuphansi kokugcoba, njll., Kuvamile.
1. Ukuthambisa okunganele
Imbangela eqondile yokugqoka: ukuthambisa okunganele. Ukuntuleka kwamafutha nakanjani kuzodala ukuthambisa okunganele, kepha ukuthambisa okunganele akubangelwa ukuntuleka kwamafutha.
Izizathu ezintathu ezilandelayo zingadala nokuthambisa okunganele:
I-grubtant ayikwazi ukufinyelela ezindaweni ezithwala.
Yize uwoyela wokugcoba usufinyelele endaweni ethwalayo, ukubonakala kwayo kuncane kakhulu ukuba kwakhiwe ifilimu lamafutha lokukhulu okwanele.
Yize uwoyela wokuthambisa usufikile ebusweni bomthwabi, ubolile ngenxa yokushisa ngokweqile futhi awukwazi ukugcoba.
Kubangele imiphumela emibi: inethiwekhi yokumunca kawoyela noma i-oyili yokuphangwa kwamapayipi, ukwehluleka kwepompo kawoyela, njll. Kuzothinta ukulethwa kwamafutha okugcoba, futhi uwoyela wokuthambisa awukwazi ukufinyelela ebusweni bokuhluphana kude nepompo yamafutha. Inetha lamafutha okuvumela kanye nephampu kawoyela kujwayelekile, kepha ukugqoka okuthwala, ukucaciswa ngokweqile, njll. Ibangela ukuvuza kwamafutha kanye nengcindezi ephansi yamafutha, okuzokwenza indawo yokucindezela kude ne-oyili ayikwazi ukuthola uwoyela wokuthambisa, okuholele ekugqokeni nasekugqokeni.
Ngenxa yezizathu ezahlukahlukene (kufaka phakathi isigaba sokuqalisa se-compressor), izinga lokushisa lendawo yokushayela ngaphandle kokuthambisa lizovuka ngokushesha, futhi uwoyela wokuthambisa uzoqala ukubola ngemuva kwe-175 ° C. "Ukufutheka okunganele okunganele - okuphambana nokushisa okuphezulu-uwoyela okuvuthayo" kungumjikelezo ojwayelekile onobubi, kanye nezingozi eziningi ezinonya, kufaka phakathi ukuxhumeka okuxhumene nokukhiya i-shaft kanye ne-piston jamming, kuhlobene nalomjikelezo ononya. Lapho ungena esikhundleni sepuleti ye-valve, hlola ukugqokwa kwe-piston pin.
2. Ukuntuleka kwamafutha
Ukuntuleka kwamafutha kungenye yezimpawu ezikhonjwe kakhulu ze-compressor. Lapho i-compressor ishoda kawoyela, kunamafutha amancane noma akukho okuthambisayo ku-crankcase.
Amafutha okugcoba akhishwe ku-compressor awabuyi emuva: i-compressor izoba mfushane kawoyela uma uwoyela wokuthambisa angabuyi.
Kunezindlela ezimbili zokubuya uwoyela kusuka ku-compressor:
Eyodwa i-oyili yokubuyisa uwoyela.
Enye yipayipi lokubuya kawoyela.
Isihlukanisi samafutha sifakiwe kwipayipi eliphuma ngaphandle kwe-compressor, elingehlukanisa ama-50-95% amafutha, ngokubuyiselwa kwamafutha aphezulu kanye nesivinini esikhulu, okunciphisa kakhulu inani lokungena kohlelo ngaphandle kwesikhathi sokubuya kawoyela. Okwezinhlelo zokugcina ezibandayo ezinamapayipi amade ikakhulukazi, kugcwala amasistimu okwenzakabule ama-Ice, kanye nemishini yokumisa iqhwa elinamazinga okushisa aphezulu kakhulu, ukufakwa kokushintshana kwamafutha asebenza kahle kungadlula isikhathi esisebenzayo se-compressor ngaphandle kokuqala kwe-frill ngemuva kokuqala. Buyela esigabeni senhlekelele samafutha.
Amafutha okugcoba okungahlukaniswanga azongena kulolu hlelo: izogeleza nesiqandisini epayipini ukuze kwakheke umjikelezo kawoyela.
Ngemuva kokuthi uwoyela wokuthambisa ungena ku-evaporator:
Ngakolunye uhlangothi, ngenxa yokushisa okuphansi kanye ne-solubity ephansi, ingxenye yamafutha okugcoba ihlukaniswe nesiqandisi.
Ngakolunye uhlangothi, izinga lokushisa liphansi futhi ukubonwa kuphakeme, futhi uwoyela ohlukanisiwe kulula ukunamathela odongeni olungaphakathi lwepayipi, okwenza kube nzima ukugeleza.
The Wehlisa izinga lokushisa lokuhwamuka, kulapho kunzima kakhulu ukubuya uwoyela. Lokhu kudinga ukuthi ukwakhiwa nokwakhiwa kwepayipi lokuhwamuka kwepayipi kanye nepayipi elibuyayo kumele lilungele ukubuyiselwa kwamafutha. Umkhuba ojwayelekile ukwamukela ukwakheka kwepayipi ehlelayo futhi uqinisekise ukuthi i-velocity enkulu yomoya. Okwezinhlelo eziqandisini ezinamazinga okushisa aphansi kakhulu, anjenge-85 ° C kanye -150 ° C.150 ° C.150 ° C.150 ° C.150 ° C.150 ° c
Kuzinhlelo zokusebenza ezisebenzayo, izinkinga zokubuyisa uwoyela ezibangelwa ukwakhiwa okungafanele kwama-evaporators kanye nemigqa yomoya ayijwayelekile. Ngezinhlelo ezingama-R22 kanye no-R204A, ukubuyiselwa kwamafutha komfanekiso ogcwele izikhukhula kunzima kakhulu, futhi ukwakheka kwepayipi lokubuya kawoyela kumele kuqaphele kakhulu. Ukusetshenziswa kokuhlukaniswa kwamafutha okusebenza kahle kakhulu kunganciphisa kakhulu inani lamafutha okufaka ipayipi lohlelo, ngempumelelo ukunweba isikhathi ngaphandle kokubuyiselwa kwamafutha ngepayipi elibuyayo ngemuva kokuqala.
Lapho i-compressor itholakala ephakeme kuno-vaporator, isicupho samafutha esibuyayo emugqeni wokubuya mpo siyadingeka. Ukuze uqinisekise ukubuyiselwa kwamafutha ngaphansi komthwalo ophansi, ipayipi eliqonde mpo lingathatha indawo ephindwe kabili.
Ukuqala okujwayelekile kwe-compressor akukuvumeli ukubuyiselwa kwamafutha. Ngoba isikhathi esiqhubekayo sokusebenza sifushane, i-compressor iyama, futhi asikho isikhathi sokwakha ijubane eliqinile elisezingeni eliphakeme ngepayipi elibuyayo, ngakho-ke uwoyela wokuthambisa angahlala epayipini kuphela. Uma uwoyela wokubuya ungaphansi kwamafutha okujaha, i-compressor izoba mfushane kawoyela.
Lapho ukhubazeka, izinga lokushisa lomfaki liyakhuphuka, futhi ukubonwa kwamafutha okugcoba kuyancipha, okwenza kube lula ukugeleza. Ngemuva komjikelezo we-defrost, izinga lokugeleza esiqandisi liphezulu, futhi amafutha okugcoba abhajwe azobuyela ku-compressor. Lapho kunokuvuza okuningi kwesiqandisi, isivinini sokubuya igesi sizokwehla. Uma ijubane liphansi kakhulu, uwoyela wokuthambisa uzohlala epayipi le-Return Return futhi awakwazi ukubuyela ku-compressor ngokushesha.
Idivayisi yokuvikela ukuphepha kwamafutha yokuphepha izoma ngokuzenzakalelayo lapho kungekho mafutha okuvikela i-compressor kusuka kumonakalo. Akunangilazi Ebona
Abacindezeli abahlelwe ngokugcwele (kufaka phakathi i-rotor kanye ne-scroll compressors) kanye nama-compressors apholile womoya anama-compressors okuphepha kawoyela abanazo izimpawu ezisobala lapho uwoyela uncipha, futhi ngeke baphele, futhi i-compressor izophela ngokungazi.
Umsindo we-compressor, ukudlidliza noma ukweqisa kwamanje kungahle kuhlobane nokuntuleka kwamafutha, ngakho-ke kubaluleke kakhulu ukwahlulela kahle isimo sokusebenza kwe-compressor kanye nohlelo.
3. Isiphetho
Imbangela yokuntuleka kwamafutha akuyona inani nesivinini se-compressor ephelelwa yi-oyili, kepha ukubuyiselwa kwamafutha ampofu ohlelweni. Ukufaka isihlukanisi samafutha kungabuyisa ngokushesha uwoyela futhi kunwetshwe isikhathi esisebenzayo se-compressor ngaphandle kokubuya kwamafutha. Ama-Evaporators kanye nemigqa yokubuyisa kumele yakhelwe ngokubuya kwamafutha engqondweni. Izindlela zokulungisa ezifana nokugwema ukuqala kaningi, i-defrosting yesikhathi, ephindaphinda esiqandisini ngesikhathi, futhi esikhundleni sezinto ezigqoke izingxenye ze-piston ngesikhathi futhi zisiza ukubuyisa kawoyela.
Ukubuya okuwuketshezi kanye nokufuduka okuqandisile kuzonciphisa uwoyela wokuthambisa, okungakufanele ukwakheka kwefilimu kawoyela;
Ukwehluleka kwepompo kawoyela nokuvinjwa kwe-oyela yesekethe kuthinta ukuhlinzekwa kawoyela kanye nokucindezela kawoyela, okuphumela ekusweleni kwamafutha ebusweni;
Izinga lokushisa eliphakeme lendawo yokushayela izingxabano lizothuthukisa ukubola kwamafutha okugcoba nokwenza uwoyela wokuthambisa ulahlekelwe amandla ayo okugcoba;
Ukuthambisa okunganele okubangelwa yilezi zinkinga ezintathu kuvame ukubangela ukulimala kwe-compressor. Imbangela yokuntuleka kwamafutha uhlelo. Ukufaka esikhundleni i-compressor kuphela noma ezinye izesekeli ngeke kuxazulule inkinga yokushoda kawoyela.
Ngakho-ke, ukwakhiwa kohlelo nokwakhiwa kwamapayipi kumele kubheke inkinga yokubuya kawoyela yohlelo, ngaphandle kwalokho kuzoba nezinkinga ezingapheli! Isibonelo, ngesikhathi sokwakha nokwakha, ipayipi le-Evaporator Return Return linikezwa nge-OIL Return Bend, futhi ipayipi lokuqeda amandla linikezwa nge-Check Bend. Onke amapayipi kufanele ahambise uketshezi oluqondiwe yonke indlela eya phansi, ngethambeka le-0.3 ~ 0.5%.
