Ndagwira ntchito kwa zaka 10 ngati katswiri wa firiji, ndaphunzitsa ndekha luso lofunika kwambiri pokonza firiji yosungiramo zinthu zozizira, yakale komanso yothandiza.
Choyamba, ndinaganizira za izi ndipo ndinasiya ndilankhule za momwe zinthu zosungiramo zinthu zozizira zimagwirira ntchito (makina a pistoni) zimagwirira ntchito bwino.
1 Mulingo wa mafuta uyenera kutsimikizika kuti ndi theka la dzenje lowonera mafuta (kuti zitsimikizire kuti mafuta ake ndi odzola)
2 Kutentha kwa utsi. Izi zimadalira refrigerant (R22 yomwe imagwiritsidwa ntchito nthawi zambiri siyenera kupitirira 145 °C, ndipo kuthamanga kofananako kumawonedwa patebulo)
3 Kutentha kwa kuyamwa kuyenera kukhala kokwera ndi 5-15°C kuposa kutentha kwa kuyamwa (kutentha kosungirako kupatula 5-10°C ndikofanana ndi kutentha kwa kuyamwa). Kusiyana pakati pa kutentha kwa kuyamwa ndi kutentha kwa kusunga ndi 0-5 °C ndikoyenera kwambiri. (kogwirizana ndi tebulo lofufuzira)
4 Cholekanitsa mafuta chimatha kubweza mafuta okha
5 Kutentha kwabwinobwino kwa mafuta kuyenera kukhala 40-60℃, (makina ena ali ndi zotenthetsera za crankcase)
6 Kuthamanga kwa mafuta a compressor kuyenera kukhala 0.15-0.3MP kuposa kuthamanga kwa madzi opopera
kusaka zolakwika
1. Kompresa imasiya kugwira ntchito mwadzidzidzi ikagwira ntchito
Izi nthawi zambiri zimakhala kutseka koteteza
(1) Mafuta akakhala otsika, cholumikiziracho chimagwira ntchito chikatsika kuposa mtengo wotetezera (onani ngati mafuta akutuluka mu dongosolo komanso ngati mafuta akugwira ntchito bwino)
(2) Kuthamanga kwa utsi kumakhala kwakukulu kwambiri, kokwera kuposa mtengo wotetezera, cholumikiziracho chidzagwira ntchito (onani kutentha kwa condenser)
(3) Kuthamanga kwa mafuta opaka ndi kochepa kwambiri, ndipo cholumikizira choteteza kupanikizika chosiyana chimagwira ntchito (onani momwe mafuta amayendera)
(4) Kuchuluka kwa injini, (kuyeza mphamvu yamagetsi, sinthani katundu wa chipangizo kuti ubwerere mwakale)
2. Kuthamanga kwa utsi kumakhala kwakukulu kwambiri compressor ikamathamanga
(1) Kusakwanira kwa kutenthetsa kutentha kozizira (yang'anani zida zotenthetsera, kuyenda kwa madzi kapena kuyenda kwa mpweya)
(2) Kuchuluka kwa mafuta mu condenser (kuchuluka kwa mafuta otulutsa)
(3) Pali mpweya mu dongosolo (vacuum iyenera kuchotsedwa musanachotse vuto, ndi bwino kuchedwetsa nthawi, ndipo njira yotulutsira mpweya iyenera kuyesedwa kumapeto kwa condenser)
(4) Mufiriji wambiri (kutulutsa madzi ochulukirapo mufiriji)
3. Compressor wet stroke (compressor frost)
(1) Kutseguka kwa valavu yokulitsa ndi kwakukulu kwambiri, ndipo mpweya wobwerera umadzazidwa ndi madzi (sinthani valavu yokulitsa)
(2) Valavu ya solenoid imalephera, ndipo madzi amapitirira pambuyo pozimitsa. Ndi madzi mukayatsanso (sinthani kapena konzani valavu ya solenoid)
(3) Chosungiramo zinthu mufiriji chochuluka komanso kusatulutsa mpweya wabwino (chosungiramo zinthu mufiriji chochuluka chimatuluka)
(4) Phukusi lozindikira kutentha kwa valavu yokulitsa silinaphatikizidwe bwino kapena molakwika (lolumikizidwa molingana ndi buku la malangizo a valavu yokulitsa)
4. Compressor singathe kuyatsidwa bwino, ndipo vuto lamagetsi lonse limafufuzidwa ndi multimeter
(1) Kutseka koteteza kwa compressor sikunayendetsedwe bwino. Kutumiza kwa relay sikunakonzedwenso (kubwezeretsedwanso kapena kuchepetsedwa mphamvu kuti athetse vuto, kenako nkubwezeretsanso)
(2) Mphamvu yamagetsi yadulidwa ndipo fuse yaphulika (onani mphamvu yamagetsi ndi fuse)
(3) Cholumikizira choyambira kapena cholumikizira sichikugwirizana bwino (kusintha kapena kukonza)
(4) Chida choyezera kutentha kapena choyezera chili ndi vuto (chiyang'aneni ndi choyezera, ndikuchisintha ngati chawonongeka)
(5) Kukhazikitsa kwa chowongolera kuthamanga sikoyenera (sinthani ngati pakufunika)
(6) Mota ya compressor yawonongeka (onani kukana pakati pa ma windings)
5. Valavu yokulitsa imakhala ndi vuto (ikasinthidwa valavu yokulitsa, imagwirizana ndi kutentha komwe kumagwira ntchito, ndipo malo otseguka amafanana ndi mphamvu yozizira ya compressor)
(1) chipika cha ayezi,
Chifukwa: Mu firiji muli madzi ambiri.
Chochitika: Kuzungulira chisanu ndi kusungunuka panthawi yogwira ntchito.
Yankho: Gwiritsani ntchito njira yotenthetsera ndi kukulitsa kuti muthetse vutoli kwakanthawi, kuthetseratu kuchira ndikusintha fyuluta youma
(2) Kutsekeka kwauve
Chifukwa: Pali zinyalala zambiri mu dongosolo, ndipo kukhazikitsa sikusamala. Kuwotcherera oxide scale, ndi zina zotero.
Chochitika: Evaporator sizizira ndipo sizizira. Koma kuthamanga kwa ntchito kumakhala kochepa kapena koipa.
Yankho: chotsani valavu yowonjezera ndikuiyeretsa ndi mafuta apakatikati
(3) Kutuluka kwa valavu yokulitsa
Chifukwa: kutuluka kwa sensa ya kutentha, kutuluka kwa thupi la valavu, kutuluka kwa njira yodziwira kutentha kwa thupi la valavu
Chochitika: palibe kuzizira, zotsatira zake si zabwino, kutuluka kwa madzi m'thupi la valavu kuli kofanana ndi kutsekeka kodetsedwa
Yankho: Sinthani kapena phatikizaninso thupi la valavu
(4) Kusintha kosayenera
Chifukwa: Kutsegulako ndi kochepa kwambiri kapena kwakukulu kwambiri
Chochitika: Thupi la valavu limazizira kwambiri pamene khomo lili lalikulu kwambiri, ndipo pamene khomo lili lalikulu kwambiri, pamakhala chisanu pamalo otulukira valavu popanda chisanu, ndipo compressor imabwerera mumlengalenga ndi madzi.
Yankho: sinthani valavu yowonjezera pamalo oyenera
6. Kulephera kwa fyuluta
chifukwa, kutsekeka
Chochitika: pamwamba pake pazizira, madzi sakwanira, ndipo firiji singathe kuchitika mwachizolowezi
Yankho: m'malo
Njira yowunikira kulephera kwa firiji
1. kuona
(1) Pali mame ndipo palibe chisanu kumbuyo kwa evaporator. Palibe firiji yokwanira kapena yotuluka (ngati valavu yokulitsa yasinthidwa bwino popanda kulephera)
(2) Gawo lapamwamba silili ndi chisanu ndipo theka lachiwiri ndi lozizira. Kuchajidwa kwambiri kwa refrigerant (ngati valavu yokulitsa yasinthidwa bwino popanda kulephera)
(3) Palibe mame kapena chisanu mu chitoliro chokoka madzi, ndipo firiji si yokwanira kapena yotuluka madzi
(4) Kuyeza kuthamanga kwa magazi, kuthamanga kwambiri ndi kochepa ndi kochepa kuposa kwabwinobwino, firiji yosakwanira kapena kutuluka kwa madzi.
(5) Pansi pa ntchito yachizolowezi ya valavu yowonjezera, pali chisanu chokhazikika, ndipo palibe chisanu kumbuyo kwa chotenthetsera chisanu chenicheni, ndipo firiji sikwanira.
2. Mvetserani
(1) Valavu yokulitsa, madzi otuluka amatha kumveka bwino. Phokoso la Sisi. Refrigerant si yokwanira, ngati simungathe kumva phokoso, imatsekedwa.
3. kukhudza
Chipolopolo cha compressor, silinda, payipi yoziziritsira, malo olowera ndi otulukira zosefera, zimatsimikizira ngati ndi zodetsedwa komanso zotsekeka
kulephera kwa kompresa
1. Silinda
Vuto la mafuta, kuipitsidwa kapena kusowa kwa mafuta, komanso kutentha kwa mafuta opaka
2. Phokoso losazolowereka la silinda
Chipinda cha valve chasweka, malo olowera m'malo ...
3. Mafuta a Crankcase ali ndi phokoso
Crankshaft imagundana ndi mafuta, zomangira zimakhala zomasuka, ndipo malo olumikizirana ndi akulu kwambiri
4. Kusuntha kwa compressor kumakhala kochepa
Kuchotsa pisitoni yochuluka
