I-Refrigeration Compressor Troubleshooting

Izinga lokushisa eliphakeme kakhulu lokumunca ngokuyinhloko ngenxa yokukhuphuka kokushisa okuphezulu. Qaphela: Izinga lokushisa eliphezulu lokumunca akusho ukuthi ingcindezi yokumunca iphezulu ngoba isitimu esishisa kakhulu. Ngokuvamile, ikhanda le-cylinder le-compressor kufanele libe yingxenye ebandayo futhi lishise ingxenye. Uma izinga lokushisa lokungenisa liphezulu kakhulu, ikhanda le-cylinder lizoshisa. Uma izinga lokushisa lokudonsa liphakeme kunevelu engaguquki, izinga lokushisa legesi ephumayo lizokhuphuka ngokufanele.

Isizathu:

a. Isiqandisi asanele. Ngisho noma i-valve yokwandisa isebenza kakhulu, alukho ushintsho ekunikezeni uketshezi, ukuthi izinga lokushisa lesiqandisi liphezulu ku-evaporator ukuze kukhushulwe izinga lokushisa lokudonsa.

b. I-valve yokwandisa isebenza ngomthamo omncane. Ukujikeleza kwesiqandisi sohlelo akwanele, isiqandisi esincane singena ku-evaporator, ukushisa okuphezulu kakhulu, izinga lokushisa eliphakeme lokumunca.

c. Isihlungi se-valve yokunweba sivalekile. Inani lokuhlinzekwa kwe-liquid ku-evaporator alanele, inani loketshezi lwesiqandisi liyancishiswa, futhi ingxenye yesikhala se-evaporator ithathwa umusi oshisa kakhulu, ngakho-ke izinga lokushisa lomoya wokungena liyakhuphuka.

d. ezinye izizathu.

a. Ishaja yesiqandisi ikhulu kakhulu, ithatha ingxenye yesikhala ngaphakathi kwe-condenser, ukuze ukucindezela kokuqina kuphezulu, futhi uketshezi olungena ku-evaporator luyanda. Uketshezi oluku-evaporator alukwazi ukuhwamuka ngokuphelele, ukuze igesi emuncwa i-compressor iqukethe amaconsi awuketshezi. Ngakho-ke, izinga lokushisa lomoya wokubuyisela liphola phansi, kodwa izinga lokushisa elihwamukayo alishintshi ngoba ukucindezela akunciphi, futhi ukushisa okukhulu kuyehla. Ngisho noma lungisa i-valve yokunweba, akukho ukuthuthukiswa okuningi.

b. Idigri yokuvula ye-valve yokunweba inkulu kakhulu. Ngenxa yokuthi inzwa yezinga lokushisa iboshelwe ngokukhululekile, indawo yokuxhumana enepayipi lomoya elibuyayo incane, noma inzwa yezinga lokushisa ayigoqwanga ngezinto zokuvikela ukushisa futhi indawo yokugoqa ayilungile, izinga lokushisa elilinganiswa inzwa yokushisa alilungile, eduze izinga lokushisa elizungezile, futhi i-valve yokwandisa iyasebenza. Izinga lokuvula liyakhuphuka, okuholela ekunikezeni uketshezi oluningi kakhulu.

Isizathu:

Ishaja yesiqandisi ayanele futhi izoqandiswa isuka ku-evaporator iye ku-compressor (Qaphela: idinga ukuqinisekiswa). Ukwengeza, ngenxa yezizathu zangaphandle, isiqandisi asishunqisi kahle noma singashunqisi nhlobo ku-evaporator, okungase kubangele isithwathwa esinamandla noma cindezela ngokumanzi. (Uma i-air-conditioning emaphakathi ibuyela emoyeni kabi noma isihlungi se-air-conditioning sivinjwe kanzima, ipayipi le-chiller lizoba yiqhwa futhi izinga lokushisa elikhiphayo liphansi kakhulu.) Ipayipi alivalekile kahle noma ipayipi lide kakhulu. , okungabangela izinga lokushisa lokudonsa umoya libe phezulu.

3. Izinga lokushisa lokukhipha umoya alijwayelekile

Izinto ezingaba khona: inani le-adiabatic, isilinganiso sokucindezela, izinga lokushisa lokumunca.

Izinga lokushisa lokukhipha i-compressor lingafundwa ku-thermometer kulayini wokukhipha umoya. Ihlobene nenkomba ye-adiabatic yesiqandisi, isilinganiso sokucindezela (ingcindezi ye-condensation / ingcindezi yokuhwamuka), kanye nezinga lokushisa lokumunca. Ukuphakama kwezinga lokushisa lokudonsa, ukuphakama kwesilinganiso sokucindezela kanye nezinga lokushisa eliphezulu lokukhipha umoya.

Lapho ingcindezi yokudonsa ihlala njalo, izinga lokushisa legesi yokukhipha liyakhuphuka lapho ukucindezela kokukhipha kukhuphuka; uma ukucindezela kokukhipha kungaguquki, izinga lokushisa legesi yokukhipha liyakhuphuka lapho ukucindezela kokudonsa kuncishisiwe, kokubili okubangelwa ukwanda kwesilinganiso sokucindezela. Amazinga okushisa okujiya ngokwedlulele namazinga okushisa akhipha umoya ayingozi ekusebenzeni kwe-compressor futhi kufanele kugwenywe. Amazinga okushisa aphezulu kakhulu akhipha umoya angabangela amafutha okugcoba abe mncane noma aze ashise kanye ne-coke, okona izimo zokuthambisa ze-compressor.

Izinga lokushisa legesi yokukhipha igesi lilingana nesilinganiso sokucindezela (ingcindezi ye-condensation / ingcindezi yokuhwamuka) kanye nezinga lokushisa lokumunca. Uma ukushisa okuphezulu kwezinga lokushisa lokumunca kuphezulu futhi isilinganiso sokucindezela siphezulu, izinga lokushisa legesi ephumayo lizoba phezulu. Uma ingcindezi yokudonsa kanye nezinga lokushisa kungashintshi, izinga lokushisa legesi ephumayo liyakhuphuka njengoba umfutho we-exhaust ukhuphuka.

Izizathu eziyinhloko zokwanda kwezinga lokushisa lokukhipha

a. izinga lokushisa eliphezulu lokumunca. Ngemuva kokuthi umhwamuko wesiqandisi ucindezelwe futhi izinga lokushisa lokuphuma liphakeme.

b. Izinga lokushisa lokujiya liyakhuphuka ukuze umfutho wokujiya ube phezulu, futhi. okwenza izinga lokushisa likhuphuke.

c. Ipuleti le-valve yokukhipha umoya liyachotshozwa, isitimu somfutho ophezulu sicindezelwa ngokuphindaphindiwe futhi izinga lokushisa liyakhuphuka, isilinda nekhanda le-cylinder kuyashisa, futhi inani lenkomba ye-thermometer epayipini lokukhipha umoya liyakhuphuka.

Izici zangempela ezithinta ukukhuphuka kwezinga lokushisa lokufuduka yilezi: ukusebenza kahle kokupholisa okumaphakathi kuphansi, noma isikali eseqile ku-intercooler sithinta ukushintshana kokushisa, izinga lokushisa lokumunca lesigaba sakamuva liphakeme ngempela, futhi izinga lokushisa lokuthutha nalo liyakhuphuka. Ukuvuza kwe-valve yegesi kanye nokuvuza kweringi ye-piston, okungathinti nje kuphela ukukhuphuka kwezinga lokushisa lokufuduka, kodwa futhi kushintsha ingcindezi ye-interstage. Inqobo nje uma isilinganiso sokucindezela siphezulu kunevelu evamile, izinga lokushisa lokususa lizokhuphuka.Daming Isiqandisiikhumbuza ukuthi imishini epholiswe ngamanzi ayinawo amanzi noma amanzi anganele azokwandisa izinga lokushisa lokukhipha umoya. Ingcindezi yokujiya ayijwayelekile futhi ne-exhaust pressure iyehliswa.

4.high exhaust pressure

Ukucindezela kwe-exhaust ngokuvamile kuhlobene nezinga lokushisa lokujiya. Ngaphansi kwezimo ezijwayelekile, ingcindezi yokukhipha i-compressor isondelene kakhulu nokucindezela okujiya. Ukucindezela okuphezulu kwe-exhaust kuzokwandisa amandla okucindezela futhi kunciphise i-coefficient yokudlulisa igesi, ngaleyo ndlela kunciphise ukusebenza kahle kokupholisa.

Njengoba ingcindezi yokujiya ikhula, izinga lokushisa lokukhipha i-compressor liyakhuphuka. Isilinganiso sokucindezela se-compressor siyanda, futhi i-coefficient yokudlulisa igesi iyancishiswa, ukuze umthamo wefriji we-compressor wehliswe. Ukusetshenziswa kwamandla kwenyukile. Uma izinga lokushisa legesi lokukhipha liphezulu kakhulu, ukusetshenziswa kwe-compressor lubricating oil kwanda, amafutha ayancishiswa, futhi ukugcoba kuyathinteka; lapho izinga lokushisa legesi lokukhipha igesi liseduze nendawo ye-flash yamafutha e-compressor, ingxenye yamafutha okugcoba i-carbonized futhi iqoqwe ekumunceni, Imbobo ye-valve yokukhipha ithinta ukuvalwa kwe-valve.

Ukunciphisa izinga lokushisa lendawo yokupholisa kungabangela izinga lokushisa lokufingqa lehle kanye nomfutho we-condensation wehle, kodwa lokhu kunqunyelwe izimo zemvelo futhi kunzima ukukhetha. Ukwandisa izinga lokugeleza kwendawo yokupholisa kunciphisa izinga lokushisa lokufingqa (le ndlela isetshenziswa kakhulu). Kodwa-ke, akunakwenzeka ukwandisa ukugeleza kwamanzi okupholisa noma umoya unilaterally, njengoba lokhu kuzokwandisa amandla epompo yamanzi okupholisa noma ifeni kanye nenjini, futhi kufanele kucatshangelwe ngokugcwele.

5. ukukhathala okunganele

Ukufuduka okunganele - ikakhulukazi uma kuqhathaniswa nokususwa okuklanyelwe kwe-compressor, kungenye yezinto ezivame kakhulu ukwehluleka kwe-compressor, ikakhulukazi ngenxa yezizathu ezimbalwa:

1. Isihlungi sokungenisa singcolile noma ipayipi yokudonsa i-compressor yinde kakhulu, futhi ububanzi bepayipi buncane kakhulu, okubangela ukuthi ukumelana nokudonsa kukhuphuke, okuthinta ivolumu yomoya wokungena futhi kunciphise ivolumu yegesi yokukhipha.

2. Ijubane le-compressor liyancishiswa ukuze kuncishiswe ivolumu yokukhipha umoya. Njengoba ukususwa kwe-compressor kuklanyelwe ngokuya ngobude obuthile (ikakhulukazi i-compressor yomoya), izinga lokushisa lokungena, umswakama kanye nokunikezwa kwamandla, lapho isetshenziswa endaweni edlula izinga elingenhla, njenge-compressor yomoya isetshenziswa ethafeni kuzodala. ingcindezi yokuncela ukuze yehle, njll., kanye nokufuduka nakho kuzothinteka.

3, uphawu lokupakisha aluqinile, okuholela ekuvuzeni, ukuze ivolumu yokukhipha iyancipha. Okokuqala, kungase kube ukuthi isigcwalisi ngokwaso asifaneleki; okwesibili, kungase kubangelwe ukuvuza komoya ngesikhathi sokufakwa, njengokuhuzuka noma ubunzima. Ngokuvamile, i-filler igcwele amafutha okugcoba, angagcotshwa, avalwe futhi apholile.
