A, ntchito ya mafuta odzola:
1) mu screw ndi chipinda chopondereza komanso pakati pa screw ya yin ndi yang kuti apange chisindikizo chosinthasintha, chepetsani refrigerant mu ndondomeko yopondereza kuchokera kumbali ya kuthamanga kwambiri kupita kumbali ya kuthamanga kochepa kwa kutuluka kwa madzi.
2) kuziziritsa firiji yomwe ikukanikizidwa, mafuta amathiridwa mu compressor, kuyamwa kutentha komwe kumapangidwa ndi mpweya wa firiji panthawi yokanikizidwa, kuchepetsa kutentha kwa utsi.
3) Pakati pa kapangidwe ka filimu yamafuta, jambulani filimuyo kuti ithandizire rotor, ndipo imagwira ntchito yopaka mafuta.
4) Samutsani mphamvu yosiyana ya kuthamanga kwa mpweya, yendetsani makina osinthira mphamvu, pogwiritsa ntchito njira yotulutsira ndi kuwonjezera valavu ya solenoid ya compressor, kusintha malo a chosinthira mphamvu, kuti mukwaniritse kuwongolera mphamvu ya compressor.
5) Chepetsani phokoso logwira ntchito
Kufotokozera:
Mafuta opaka mkati mwa compressor ndiye chinsinsi chosungira ntchito yabwinobwino ya compressor, mavuto ambiri opaka mafuta ndi awa:
1) zinthu zakunja zosakanikirana, zomwe zimapangitsa kuti mafuta aziipitsidwa, zomwe zimaletsa fyuluta ya mafuta.
2) Kutentha kwambiri kumapangitsa kuti mafuta awonongeke ndikutaya ntchito yopaka mafuta.
3) Kuipitsidwa kwa madzi m'dongosolo, acidization, kuwonongeka kwa injini.
Chachiwiri, kuyesa ndi kusintha mafuta oziziritsa a compressor:
Kwa wopanga makina, kuyesa ndi kusintha kwa mafuta a compressor kumagwirizana ndi kuwongolera njira yopangira. Ngati kuwongolera kwa ukhondo wa evaporator ndi condenser ndi mapaipi a makina kuli bwino, ndiye kuti kuipitsidwa kochepa mu compressor, nthawi yozindikira ndi kukonza ikhoza kukhala yayitali.
Zizindikiro zazikulu zowunikira:
1) Chizindikiro cha mtengo wa PH: acidization ya mafuta opaka mafuta idzakhudza mwachindunji moyo wa injini ya compressor, kotero acidity ya mafuta opaka mafuta iyenera kuyang'aniridwa nthawi zonse kuti ione ngati ili yoyenera. Acidity yonse ya mafuta pansi pa PH6 ikufunika kuti ilowe m'malo. Ngati acidity singayang'anitsidwe, chowumitsira chosefera cha makina chiyenera kusinthidwa nthawi zonse kuti makinawo akhale olimba.
2) Chizindikiro cha kuipitsidwa: Ngati zoipitsa mu 100ml ya mafuta oziziritsira zipitirira 5mg, tikulimbikitsa kuti musinthe mafuta oziziritsira.
3) Kuchuluka kwa madzi: Ngati apitirira 100ppm, ndikofunikira kusintha mafuta oziziritsira.
Kubwerezabwereza kwa njira:
Kawirikawiri maola 10,000 aliwonse ogwira ntchito ayenera kuyang'ana kapena kusintha mafuta, ndipo pambuyo pa opaleshoni yoyamba, maola 2500 amalimbikitsidwa kuti musinthe mafuta ndikutsuka fyuluta yamafuta. Chifukwa zotsalira za dongosolo zidzasonkhanitsidwa mu compressor pambuyo pa ntchito yovomerezeka. Chifukwa chake, mafuta odzola ayenera kusinthidwa kamodzi pa maola 2500 (kapena miyezi 3), kenako nthawi zonse malinga ndi ukhondo wa dongosolo, ngati ukhondo wa dongosolo uli wabwino, ukhoza kusinthidwa kamodzi pa maola 10000 (kapena pachaka).
Ngati kutentha kwa compressor kukupitirirabe, ndiye kuti mafuta akuwonongeka mofulumira, ndipo nthawi zonse (miyezi iwiri iliyonse) muyenera kuyang'ana mawonekedwe a mankhwala a mafuta, ndipo sanasinthidwe. Ngati simungathe kuwona nthawi zonse, mutha kutsatira tebulo lotsatirali.
Zitatu, njira yogwiritsira ntchito mafuta oziziritsa m'malo mwa firiji:
1) Kubwezeretsa mafuta mufiriji popanda kuyeretsa mkati:
Compressor imagwira ntchito yopompa kuti ibwezeretse refrigerant ya system kumbali ya condenser (dziwani kuti mphamvu yocheperako yopompa si yochepera 0.5Kg/cm2G), chotsani refrigerant kuchokera ku compressor, sungani mphamvu yamkati ngati gwero lamagetsi, ndikutulutsa mafuta a refrigerant kuchokera ku valavu yotulutsira mafuta ya compressor.
2) Sinthani mafuta ophikira mufiriji ndikutsuka mkati:
Tsukani mafuta monga tafotokozera pamwambapa, mafuta oziziritsa atachotsedwa ndipo kuthamanga mkati ndi kunja kwa compressor kuli koyenera, gwiritsani ntchito wrench ya hexagonal kuti mutsegule mabotolo a flange, chotsani cholumikizira cha fyuluta ya mafuta ndikuchotsa flange ya dzenje (kapena flange ya switch ya mafuta), chotsani zonyansa mu thanki ya mafuta ya compressor, ndikuwona ngati maukonde a dzenje la fyuluta ya mafuta asweka, ndikutulutsa matope ndi zonyansa zomwe zili pamenepo, kapena sinthani fyuluta ya mafuta ndi yatsopano, dziwani kuti Mukasintha nati yatsopano yolumikizira fyuluta iyenera kukulungidwa bwino ndikutsekedwa bwino kuti isatayike mkati; m'mphepete mwa cholumikizira cha fyuluta ya mafuta muyenera kusinthidwa ndi watsopano kuti mupewe kutayikira mkati; m'mphepete wina wa flange ukulimbikitsidwanso kusinthidwa.
IV. Zindikirani:
1. Mafuta osakaniza opangidwa ndi zinthu zoziziritsira sayenera kusakanikirana ndi mitundu yosiyanasiyana, makamaka mafuta amchere ndi mafuta opangidwa ndi ester.
2. Ngati mukusintha mafuta oziziritsa osiyanasiyana, samalani ndi mafuta oziziritsa oyambilira omwe atsala mu dongosolo kuti asachotsedwe.
3. Mafuta ena ndi a hygroscopic, choncho musawaike mafutawo mlengalenga kwa nthawi yayitali. Yesetsani kuchepetsa nthawi yowonekera momwe mungathere ndipo mutulukemo momwe mungathere mukakhazikitsa.
4. Ngati makinawo ali ndi vuto la kuwotcha kwa injini ya compressor, samalani kwambiri kuchotsa asidi wotsala mu makinawo mukasintha makina atsopano, ndikuwona ngati asidi wa mafuta oziziritsira agwiritsidwa ntchito maola makumi asanu ndi awiri mphambu awiri, ndikulimbikitsidwa kusintha mafuta oziziritsira ndi chowumitsira chosefera kuti muchepetse kuwonongeka kwa asidi. Pambuyo pake, yesani kapena sinthani mafuta oziziritsira atatha pafupifupi mwezi umodzi akugwira ntchito.
5. Ngati makinawo achita ngozi yokhudza kulowa kwa madzi, samalani kwambiri kuti muchotse madziwo bwino, ndipo kuwonjezera pa kusintha mafuta oziziritsa, samalani kwambiri kuti muzindikire acidity ya mafutawo ndikuyikanso mafuta atsopano ndi chowumitsira fyuluta pakapita nthawi.
