Isicompressor yefriji yokulungisa ingxaki

Ubushushu obugqithisileyo bokufunxa bubangelwa kukwanda kobushushu obugqithisileyo. Qaphela: Ubushushu obuphezulu bokufunxa akuthethi ukuba uxinzelelo lokufunxa luphezulu kuba ngumphunga oshushu kakhulu. Ngokuqhelekileyo, intloko ye-cylinder ye-compressor kufuneka ibe nesiqingatha esibandayo kunye nesiqingatha sishushu. Ukuba iqondo lokushisa liphezulu kakhulu, intloko yesilinda iya kutshisa. Ukuba iqondo lokushisa lokufunxa liphezulu kunexabiso elimiselweyo, iqondo lokushisa legesi yokukhupha liya kunyuka ngokufanelekileyo.

Isizathu:

a. Ifriji ayonelanga. Nokuba ivalve yokwandisa isebenza kakhulu, akukho tshintsho kunikezelo lolwelo, ukuba ubushushu befriji buphezulu kwi-evaporator ukuze inyuse ubushushu bokufunxa.

b. Ivalve yokwandisa isebenza kwindawo encinci. Ukujikeleziswa kwefriji yenkqubo akwanelanga, ifriji encinci ingena kwi-evaporator, ukushisa okuphezulu, ubushushu obuphezulu bokufunxa.

c. Isihluzo sevalve yokwandisa sivalekile. Ubungakanani bonikezelo lwamanzi kwi-evaporator alunelanga, inani le-refrigerant liquid liyancitshiswa, kwaye inxalenye yendawo ye-evaporator ithathwa ngumphunga ogqithisiweyo, ngoko ukushisa komoya wokungena kwanda.

d. ezinye izizathu.

a. Intlawulo yefriji ininzi kakhulu, ithatha indawo yendawo ngaphakathi kwe-condenser, ukwenzela ukuba uxinzelelo lwe-condensing luphezulu, kwaye ulwelo olungena kwi-evaporator luyanda. I-liquid kwi-evaporator ayinakutshitshiswa ngokupheleleyo, ukwenzela ukuba igesi efunwe yi-compressor iqulethe i-droplets yamanzi. Ngaloo ndlela, iqondo lokushisa lokubuya kwe-air duct liphola phantsi, kodwa iqondo lokushisa eliphumayo alitshintshi ngenxa yokuba uxinzelelo alunciphi, kwaye ukushisa okukhulu kuyancipha. Nokuba uhlengahlengiso lwevalve yokwandiswa, akukho phuculo lungako.

b. Idigri yokuvula yevalve yokwandisa inkulu kakhulu. Ngenxa yokuba i-sensor yeqondo lokushisa ibotshelelwe ngokukhululekileyo, indawo yoqhagamshelwano kunye nombhobho womoya wokubuyisela incinci, okanye inzwa yeqondo lokushisa ayisongelwanga ngezinto ezikhusela ubushushu kwaye indawo yokugquma ayilunganga, ubushushu obulinganiswe yinzwa yobushushu ayichanekanga, kufutshane. ubushushu be-ambient, kunye nevalve yokwandisa iyasebenza. Iqondo lokuvula liyenyuka, okukhokelela kunikezelo lwamanzi kakhulu.

Isizathu:

Intlawulo yefriji ayanelanga kwaye iya kukhenkcezwa kwi-evaporator ukuya kwicompressor (Qaphela: kufuneka kuqinisekiswe). Ukongeza, ngenxa yezizathu zangaphandle, ifriji ayiphumi kakuhle okanye ingaphumi kwaphela kwi-evaporator, enokubangela iqabaka elibukhali okanye icinezele ngokumanzi. (Ukuba i-air-conditioning esembindini ibuyela emoyeni kakubi okanye i-air-conditioning filter ivalekile, umbhobho we-chiller uya kuba ngumkhenkce kwaye ubushushu bokukhupha buphantsi kakhulu.) Umbhobho awuvalwanga kakuhle okanye umbhobho mde kakhulu. , enokubangela ubushushu bokufunxa umoya phezulu.

3. Iqondo lobushushu lokuphuma aliqhelekanga

Izinto ezinokubakho: ixabiso le-adiabatic, umlinganiselo wokunyanzeliswa, ubushushu bokufunxa.

Ubushushu bokukhutshwa kwe-compressor bunokufundwa kwi-thermometer kumgca wokukhupha. Inxulumene nesalathiso se-adiabatic yefriji, umlinganiselo woxinzelelo (uxinzelelo lwe-condensation / uxinzelelo lwe-evaporation), kunye nokushisa okufunxayo. Okukhona iqondo lobushushu lokufunxa liphezulu, kokukhona umlinganiselo wokucinezelwa uphezulu kwaye kokukhona ubushushu obuphezulu bokukhupha.

Xa uxinzelelo lwe-suction luhlala luhlala, ukushisa kwegesi yokukhupha kuphakama xa uxinzelelo lokukhupha lukhula; ukuba uxinzelelo lwe-exhaust aluguquki, ukushisa kwegesi yokukhupha kuphakama kwakhona xa uxinzelelo lwe-suction luyancipha, zombini ezo zibangelwa ukunyuka komlinganiselo wokunyanzeliswa. Ukushisa okugqithisileyo kunye nokukhupha ukushisa kuyingozi ekusebenzeni kwecompressor kwaye kufuneka kugwenywe. Ukushisa okugqithisileyo okugqithisileyo kunokubangela ukuba i-oyile yokuthambisa ibe mncinci okanye ide itshiswe kunye ne-coke, ephazamisa iimeko zokuthambisa zecompressor.

Iqondo lobushushu lerhasi yokukhupha ilingana nomlinganiselo woxinzelelo (uxinzelelo lwecondensation / uxinzelelo lomoya) kunye neqondo lobushushu lokufunxa. Ukuba ubushushu obuphezulu bobushushu bokufunxa buphezulu kwaye umlinganiselo woxinzelelo uphezulu, ubushushu berhasi yokukhupha buya kuba phezulu. Ukuba uxinzelelo lokufunxa kunye nobushushu abutshintshi, iqondo lobushushu legesi yokuphuma liyenyuka njengoko uxinzelelo lokukhupha lukhula.

Izizathu eziphambili zokunyuka kweqondo lokushisa lokukhupha

a. ubushushu obuphezulu bokufunxa. Emva kokuba umphunga wefriji uxinzelelwe kwaye ubushushu bokukhupha buphezulu.

b. Iqondo lobushushu elijiyisayo liyenyuka ukuze uxinzelelo lokujiya lubephezulu, nalo. kubangela ukunyuka kweqondo lokushisa.

c. I-plate ye-valve yokukhupha iyachithwa, i-steam yoxinzelelo oluphezulu ixinzelelwe ngokuphindaphindiweyo kwaye ubushushu buphakama, i-cylinder kunye nentloko ye-cylinder iyatshisa, kunye nexabiso le-thermometer ebonisa kwi-exhaust pipe nayo iphakama.

Izinto ezichanekileyo ezichaphazela ukunyuka kweqondo lokushisa lokufuduka zezi: ukusebenza kakuhle kokupholisa okuphakathi kuphantsi, okanye umlinganiselo ogqithiseleyo kwi-intercooler uchaphazela ukutshintshiselana kobushushu, ukushisa kweqondo lokugqibela kubaluleke kakhulu, kwaye ubushushu bokufuduka buyanda. Ivalve yegesi iyavuza kunye nokuvuza kweringi yepiston, engachaphazeli nje kuphela ukunyuka kweqondo lobushushu, kodwa iphinde itshintshe uxinzelelo lwe-interstage. Ngethuba nje umlinganiselo wokunyanzeliswa uphezulu kunexabiso eliqhelekileyo, iqondo lokushisa lokufuduka liya kunyuka.Daming ifrijiikhumbuza ukuba oomatshini abapholileyo ngamanzi abanamanzi okanye amanzi angonelanga baya kwandisa ubushushu bombhobho. Uxinzelelo lwe-condensing aluqhelekanga kwaye uxinzelelo lwe-exhaust luyathotywa.

4.uxinzelelo oluphezulu lokukhupha

Uxinzelelo lokukhupha ngokuqhelekileyo luhambelana nenqanaba lobushushu obuncitshisiweyo. Ngaphantsi kweemeko eziqhelekileyo, uxinzelelo lwe-compressor discharge lusondele kakhulu kuxinzelelo lokunciphisa. Uxinzelelo oluphezulu lokukhupha luya kwandisa amandla oxinzelelo kunye nokunciphisa i-coefficient yokuhanjiswa kwegesi, ngaloo ndlela ukunciphisa ukusebenza kokupholisa.

Njengoko uxinzelelo lwe-condensing lukhula, iqondo lokushisa lokukhupha i-compressor liyenyuka. Umlinganiselo wokunyanzeliswa kwe-compressor wanda, kwaye i-coefficient yokuhanjiswa kwegesi iyancitshiswa, ukwenzela ukuba amandla efriji ye-compressor athotywe. Ukusetyenziswa kwamandla kuye kwanda. Ukuba ukushisa kwegesi yokukhupha kuphezulu kakhulu, ukusetyenziswa kweoli yokucoca i-compressor kunyuswa, ioli iyancitshiswa, kwaye i-lubrication ichaphazelekayo; xa i-exhaust yegesi yokushisa isondele kwi-flash point ye-oyile ye-compressor, inxalenye yeoli yokuthambisa i-carbonized kwaye iqokelelwe kwi-suction, i-port exhaust valve ichaphazela ukutywinwa kwevalve.

Ukunciphisa ukushisa kwendawo yokupholisa kunokubangela ukuba ukushisa kwe-condensation kuhla kwaye uxinzelelo lwe-condensation luyancipha, kodwa oku kunqunyelwe yimeko yendalo kwaye kunzima ukukhetha. Ukunyusa izinga lokuhamba kwendawo yokupholisa kunciphisa ubushushu bokunciphisa (le ndlela isetyenziswa ngakumbi). Nangona kunjalo, akunakwenzeka ukwandisa ukuhamba kwamanzi okupholisa okanye umoya unilaterally, njengoko oku kuya kwandisa amandla epompo yamanzi okupholisa okanye i-fan kunye ne-motor, kwaye kufuneka ithathelwe ingqalelo ngokubanzi.

5. ukukhupha okungonelanga

Ukufuduswa okungonelanga - ngakumbi xa kuthelekiswa nokufuduswa okulungiselelweyo kwecompressor, yenye yezona zinto zinokusilela kwicompressor, ikakhulu ngenxa yezizathu ezininzi:

1. Isihluzo sokungena sihlanjululwe okanye i-compressor suction pipe ide kakhulu, kwaye ububanzi bombhobho buncinci kakhulu, obangela ukuba ukuchasana kwe-suction kunyuke, okuchaphazela umthamo womoya wokungenisa kunye nokunciphisa umthamo wegesi yokukhupha.

2. Isantya secompressor siyancitshiswa ukunciphisa umthamo wokukhupha. Ekubeni ukufuduswa kwecompressor kuyilwe ngokomphakamo othile (ikakhulukazi icompressor yomoya), ubushushu bokungena, ukufuma kunye nonikezelo lwamandla, xa isetyenziswa kwindawo engaphaya komgangatho ongasentla, njengecompressor yomoya isetyenziswa kwithafa iya kubangela. uxinzelelo lokufunxa ukuncipha, njl., kunye nokufuduswa kuya kuchaphazeleka.

I-3, isitywina sokupakisha asingqongqo, okubangela ukuvuza, ukwenzela ukuba umthamo wokukhupha unciphise. Okokuqala, kusenokwenzeka ukuba isigcwalisi ngokwaso asifanelekanga; okwesibini, kunokubangelwa ukuvuza komoya ngexesha lofakelo, njenge-abrasion okanye i-strain. Ngokuqhelekileyo, i-filler igcwele ioli yokuthambisa, enokuthi ifakwe i-lubrication, ivalwe kwaye ipholile.
