Ukwabelana ngolwazi lokugcinwa kwefriji endaweni ebandayo

Ngisebenze iminyaka eyi-10 njengochwepheshe wefriji, ngifundise mina mathupha ulwazi olubalulekile lokugcinwa kwefriji endaweni ebandayo, olujwayelekile nolusebenzayo

Okokuqala, ngicabange ngakho futhi ngivumele ngikhulume ngesimo sokusebenza okuvamile kwesitoreji esibandayo (umshini we-piston)
1 Izinga likawoyela kumele liqinisekiswe ukuthi liyi-1/2 yembobo yokubona uwoyela (ukuqinisekisa ukugcotshwa kwawo)
2 Izinga lokushisa lokukhipha ugesi. Lokhu kuncike ku-refrigerant (i-R22 evame ukusetshenziswa akufanele ibe ngaphezu kuka-145 °C, futhi ingcindezi ehambisanayo ihlolwe etafuleni)
3 Izinga lokushisa lokumunca kumele libe ngu-5-15°C ngaphezu kwezinga lokushisa lokumunca (izinga lokushisa lokugcina lingaphansi kuka-5-10°C lilingana nezinga lokushisa lokumunca). Umehluko phakathi kwezinga lokushisa lokumunca kanye nezinga lokushisa lokugcina lingu-0-5°C ufaneleka kakhulu. (okuhambisana nethebula lokuhlola)
4 Isihlukanisi samafutha singabuyisa uwoyela ngokuzenzakalelayo
5 Izinga lokushisa elijwayelekile likawoyela kufanele libe ngu-40-60℃, (eminye imishini ifakwe ukushisa kwe-crankcase)
6 Umfutho kawoyela we-compressor kufanele ube phezulu ngo-0.15-0.3MP kunomfutho wokumunca

ukuxazulula izinkinga

1. I-compressor iyayeka ukusebenza ngokuzumayo ngesikhathi sokusebenza
Lokhu kuvame ukuba ukuvala okuvikelayo
(1) Uma izinga likawoyela liphansi, i-relay izosebenza uma iphansi kunenani lokuvikela (hlola ukuthi uhlelo luvuza uwoyela nokuthi uwoyela usebenza kahle yini)
(2) Umfutho wokukhipha ugesi uphakeme kakhulu, uphakeme kakhulu kunenani lokuvikela, i-relay izosebenza (hlola ukushabalaliswa kokushisa kwe-condenser)
(3) Umfutho wamafutha okugcoba uphansi kakhulu, futhi i-differential pressure protection relay iyasebenza (hlola uhlelo lokugcoba)
(4) Ukulayisha ngokweqile kwenjini, (linganisa ugesi, lungisa umthwalo weyunithi ukuze ubuyele esimweni esijwayelekile)
2. Umfutho wokukhipha ugesi uphezulu kakhulu uma i-compressor isebenza
(1) Ukungapheleli kokushisa okufudumezayo (hlola imishini yokufudumeza, ukugeleza kwamanzi noma ukugeleza komoya)
(2) Ukuqongelela uwoyela ngokweqile ku-condenser (ukuqongelela uwoyela okhipha amanzi)
(3) Kukhona umoya ohlelweni (i-vacuum kumele ikhishwe ngaphambi kokulungisa amaphutha, kungcono ukulibazisa isikhathi esithile, futhi indlela yokukhipha umoya kufanele izanywe ekugcineni okuphezulu kwe-condenser)
(4) Isiqandisi esiningi kakhulu ohlelweni (sikhipha isiqandisi esiningi kakhulu)
3. I-compressor wet stroke (i-compressor frost)
(1) Ukuvulwa kwevalvu yokunweba kukhulu kakhulu, futhi igesi ebuyayo igcwele uketshezi (lungisa ivalvu yokunweba)
(2) Ivalvu ye-solenoid iyahluleka, futhi ukunikezwa koketshezi kuyaqhubeka ngemva kokuvala. Ngoketshezi uma uvula futhi (shintsha noma lungisa ivalvu ye-solenoid)
(3) Isiqandisi esiningi kakhulu kanye nokuhwamuka okubi (isiqandisi esiningi siyavuza)
(4) Iphakheji yokuzwa izinga lokushisa kwevalvu yokunweba ayihlanganiswanga kahle noma ngendlela engafanele (ihlanganiswe ngokwencwadi yemiyalelo yevalvu yokunweba)
4. I-compressor ayikwazi ukuqaliswa ngokujwayelekile, futhi iphutha likagesi elijwayelekile lihlolwa nge-multimeter
(1) Ukuvalwa okuvikelayo kwe-compressor akusingathwanga kahle. I-relay ayisethwa kabusha (isethwe kabusha noma inqanyulwe ngenkani ukuze kulungiswe iphutha, bese ibuyiselwa esimweni sayo)
(2) Ugesi uyanqanyulwa bese i-fuse ishaywa (hlola ugesi kanye ne-fuse)
(3) I-relay yokuqala noma i-contactor ayixhumene kahle (ukushintsha noma ukulungisa)
(4) I-thermostat noma inzwa inephutha (yihlole ngemitha, bese uyishintsha uma yonakele)
(5) Ukusethwa kwesilawuli sokucindezela akunangqondo (lungisa njengoba kudingeka)
(6) Injini ye-compressor yonakele (hlola ukumelana phakathi kwama-windings)
5. Ivalvu yokunweba inephutha (uma ivalvu yokunweba ishintshwa, ihambisana nokushisa okusebenzayo, kanti imbobo ihambisana nomthamo wokupholisa wecompressor)
(1) ibhlogo leqhwa,
Isizathu: Okuqukethwe kwamanzi amaningi kwesiqandisi.
Isenzakalo: Ukusabalala kweqhwa nokuncibilikisa ngesikhathi sokusebenza.
Isixazululo: Sebenzisa indlela yokushisa nokwandisa ukuxazulula inkinga okwesikhashana, ukuqeda ngokuphelele ukululama bese ushintsha isihlungi esomile
(2) Ukuvinjelwa okungcolile
Isizathu: Kunokungcola okuningi kakhulu ohlelweni, futhi ukufakwa akuqapheli. Isikali se-oxide yokushisela, njll.
Isenzakalo: I-evaporator ayiqandi futhi ayipholi. Kodwa ingcindezi yokusebenza iphansi noma ayibi
Isixazululo: susa ivalvu yokwandisa bese uyihlanza ngamafutha aphakathi
(3) Ukuvuza kwevalvu yokwandisa
Isizathu: ukuvuza kwenzwa yokushisa, ukuvuza komzimba we-valve, ukuvuza kwendlela yokuzwa ukushisa komzimba we-valve
Isenzakalo: akukho ukupholisa, umphumela awumuhle, ukuvuza emzimbeni we-valve kufana nokuvinjelwa okungcolile
Isixazululo: Shintsha noma uhlanganise kabusha umzimba wevalvu
(4) Ukulungiswa okungafanele
Isizathu: Umgodi mncane kakhulu noma mkhulu kakhulu
Isenzakalo: Umzimba wevalvu uqandisiwe wonke uma umgodi umkhulu kakhulu, futhi uma umgodi umkhulu kakhulu, kuba neqhwa endaweni yokukhipha umzimba wevalvu ngaphandle kweqhwa, bese i-compressor ibuyela emoyeni noketshezi.
Isixazululo: lungisa ivalvu yokunweba ibe sendaweni efanele
6. Ukwehluleka kwesihlungi
imbangela, ukuvaleka
Isenzakalo: ubuso buqandisiwe, uketshezi alwanele, futhi ukugcinwa kwesiqandisi akukwazi ukwenziwa ngendlela evamile
Isixazululo: shintsha
Indlela yokuhlaziya ukwehluleka kwesiqandisi
1. ukubona
(1) Kukhona amazolo futhi akukho qhwa engxenyeni engemuva ye-evaporator. I-refrigerant ayanele noma iyavuza (uma i-valve yokwandisa ilungiswe kahle ngaphandle kokwehluleka)
(2) Ingxenye engenhla ayinayo iqhwa kanti ingxenye yesibili iqandisiwe. Ukushaja ngokweqile kwe-refrigerant (uma i-valve yokwandisa ilungiswe kahle ngaphandle kokwehluleka)
(3) Akukho mazolo noma iqhwa epayipini lokumunca, futhi isiqandisi asanele noma sivuza
(4) Isilinganiso sokucindezela, ukucindezela okuphezulu nokuphansi kuphansi kunamanani ajwayelekile, i-refrigerant enganele noma ukuvuza
(5) Ngaphansi kwezimo zokusebenza ezijwayelekile zevalvu yokunweba, kukhona iqhwa elibonakalayo elithambekile, futhi akukho qhwa ngemuva kwe-evaporator yangempela yeqhwa, futhi i-refrigerant ayanele.
2. Lalela
(1) I-valve yokwandisa, ukugeleza koketshezi kungezwakala ngokujwayelekile. Umsindo kaSisi I-refrigerant ayanele, uma ungayizwa umsindo, ivinjiwe.
3. ukuthinta
Igobolondo le-compressor, isilinda, ipayipi elijiyile, indawo yokungena kanye nendawo yokuphuma kwesihlungi, kunquma ukuthi ingcolile futhi ivinjiwe yini

ukwehluleka kwe-compressor

1. Isilinda

Inkinga kawoyela, ukungcola noma ukuntuleka kwamafutha kanye nokushisa kwamafutha okugcoba

2. Umsindo ongajwayelekile wesilinda

Ipuleti levalvu liphukile, isikhala sesilinda sincane kakhulu, futhi isikhala sephini sikhulu kakhulu

3. Uwoyela we-crankcase unomsindo

I-crankshaft ishayisana namafutha, izikulufo zikhululekile, futhi indawo evulekile ehlangene inkulu kakhulu

4. Ukufuduka kwe-compressor kuba kuncane

Ukususwa okukhulu kokuguguleka kwepiston
