Choyamba, ntchito ya mafuta odzola:
1) Chisindikizo champhamvu chimapangidwa pakati pa sikulu, chipinda chopondereza ndi zomangira zachimuna ndi zachikazi kuti muchepetse kutuluka kwa refrigerant kuchokera kumbali ya kupanikizika kwakukulu kupita kumbali ya kupsinjika kochepa panthawi yopondereza.
2) Kuti muziziritse firiji yokakamizidwa, mafuta amalowetsedwa mu compressor kuti atenge kutentha komwe kumapangidwa ndi mpweya wozizira panthawi yokakamizidwa ndikuchepetsa kutentha kwa utsi.
3) Filimu yamafuta imapangidwa pakati pa bearing ndi screw kuti ithandizire rotor ndikuyipaka mafuta.
4) Imatumiza mphamvu yosiyana ya kuthamanga, imayendetsa makina osinthira mphamvu, ndikusintha malo a chosinthira mphamvu kudzera mu ntchito ya valavu yokweza ndi kutsitsa ya compressor kuti ikwaniritse kuwongolera kosintha mphamvu kwa compressor.
5) Chepetsani phokoso lothamanga
fotokozani:
Mafuta opaka mkati mwa compressor ndiye chinsinsi chosungira ntchito ya compressor. Mavuto ambiri a mafuta opaka ndi awa:
1) Zinthu zakunja zimasakanizidwa, zomwe zimayambitsa kuipitsa mafuta ndikutseka fyuluta yamafuta.
2) Kutentha kwambiri kumayambitsa kuwonongeka kwa mafuta opaka mafuta ndi kutayika kwa ntchito yopaka mafuta.
3) Kuipitsidwa kwa madzi, acidization ndi kuwonongeka kwa injini mu dongosolo.
2. Kuyang'anira ndi kusintha mafuta oziziritsa a compressor:
Kwa opanga makina, njira yodziwira ndi kusintha mafuta oziziritsa a compressor imagwirizana ndi kayendetsedwe ka njira yopangira. Ngati ukhondo wa evaporator, condenser ndi payipi ya makinawo ziwongoleredwa bwino, zoipitsa zomwe zimalowa mu compressor zidzakhala zochepa, ndipo nthawi yowunikira ndi kukonza ikhoza kukulitsidwa pang'ono.
Zizindikiro zazikulu zowunikira:
1) Chizindikiro cha mtengo wa PH: Kuchuluka kwa asidi mu mafuta opaka mafuta kudzakhudza mwachindunji moyo wa injini ya compressor, kotero ndikofunikira kuyang'ana nthawi zonse ngati asidi mu mafuta opaka mafuta ali oyenerera. Nthawi zambiri, asidi mu mafuta opaka mafuta ndi otsika kuposa PH6 ndipo amafunika kusinthidwa. Ngati asidi sangathe kufufuzidwa, chowumitsira fyuluta cha makina chiyenera kusinthidwa nthawi zonse kuti makinawo akhale olimba.
2) Chizindikiro cha digiri ya kuipitsidwa: Ngati zoipitsa mu 100ml ya mafuta oziziritsira zipitirira 5mg, tikulimbikitsa kuti musinthe mafuta oziziritsira.
3) Kuchuluka kwa madzi: kupitirira 100ppm, mafuta oziziritsira ayenera kusinthidwa.
Kusintha kwa kayendedwe ka zinthu:
Kawirikawiri, mafuta opaka mafuta ayenera kufufuzidwa kapena kusinthidwa maola 10,000 aliwonse kuyambira pamene ntchito yayamba, ndipo pambuyo pa opaleshoni yoyamba, tikulimbikitsa kusintha mafuta opaka mafuta ndikutsuka fyuluta ya mafuta maola 2,500 aliwonse. Zotsalira zomwe zimachitika chifukwa cha kusonkhana kwa makina zidzasonkhanitsidwa mu compressor pambuyo pa ntchito yeniyeniyo. Chifukwa chake, mafuta opaka mafuta ayenera kusinthidwa maola 2,500 aliwonse (kapena miyezi 3), kenako nthawi ndi nthawi malinga ndi ukhondo wa makinawo. Ngati ukhondo wa makinawo ndi wabwino, ukhoza kusinthidwa maola 10,000 aliwonse (kapena chaka chilichonse).
Ngati kutentha kwa utsi wa compressor kukusungidwa kutentha kwambiri kwa nthawi yayitali, kuwonongeka kwa mafuta opaka mafuta kudzapitirira mofulumira, ndipo makhalidwe a mankhwala a mafuta opaka mafuta ayenera kuyang'aniridwa nthawi zonse (miyezi iwiri iliyonse), ndikusinthidwa ngati sakuyenerera. Ngati kuyang'aniridwa nthawi zonse sikungatheke, kungathe kuchitika motsatira tebulo lotsatirali.
3. Njira yogwiritsira ntchito mafuta oziziritsa m'malo mwa firiji:
1) Kusintha mafuta oziziritsira popanda kuyeretsa mkati:
Kompresa imagwira ntchito yopompa kuti ibwezeretse choziziritsira cha makinawo kumbali ya kondresa (dziwani kuti mphamvu yocheperako yopompa si yochepera 0.5Kg/cm2G), chotsani choziziritsiracho mu kompresa, sungani mphamvu yamkati ngati gwero lamagetsi, ndikuyika mufiriji. Mafuta amachotsedwa mu valavu yotulutsira mafuta ya kompresa.
2) Bwezerani mafuta oziziritsira ndi kuyeretsa mkati:
Ntchito yotulutsa mafuta ndi monga tafotokozera pamwambapa. Mafuta oziziritsa akachotsedwa ndipo mphamvu mkati ndi kunja kwa compressor yakhazikika, masulani mabotolo a flange ndi wrench ya Allen, ndikuchotsa cholumikizira cha filter ya mafuta ndi flange ya dzenje lochotsera (kapena flange ya switch ya mafuta). Mukatsuka, chotsani zonyansa zomwe zili mu thanki ya mafuta ya compressor, yang'anani ngati maukonde a filter ya mafuta awonongeka, ndikuchotsa matope, zonyansa, ndi zina zotero zomwe zili pamenepo, kapena sinthani filter ya mafuta ndi yatsopano. Nati yolumikizira fyuluta iyenera kumangidwa ndikutsekedwa kuti isatayike mkati; gasket yamkati ya cholumikizira cha filter ya mafuta iyenera kusinthidwa ndi yatsopano kuti isatayike mkati; ma gasket ena a flange akulangizidwanso kuti asinthidwe.
Zolemba zinayi:
1. Mafuta osakaniza opangidwa ndi zinthu zoziziritsira sayenera kusakanikirana ndi mitundu yosiyanasiyana, makamaka mafuta amchere ndi mafuta opangidwa ndi ester.
2. Ngati musintha mafuta oziziritsa a mtundu wina, samalani kuti muchotse mafuta oziziritsa oyambira omwe atsala mu makinawo.
3. Mafuta ena ali ndi mphamvu zoyezera kutentha, choncho musawaike mafuta mufiriji mumlengalenga kwa nthawi yayitali. Mukayika, chepetsani nthawi yowonekera ndipo chitani bwino ntchito yoyeretsa.
4. Ngati injini ya compressor yayaka mu makina, chisamaliro chapadera chiyenera kuperekedwa pochotsa zinthu zotsala za asidi mu makina posintha makina atsopano, ndipo asidi wa mafuta oziziritsira ayenera kufufuzidwa patatha maola 72 akugwira ntchito. Ndikofunikira kusintha mafuta oziziritsira ndi fyuluta yowumitsa. , kuchepetsa kuthekera kwa dzimbiri la asidi. Mukatha kugwira ntchito kwa mwezi umodzi, onaninso kapena sinthani mafuta oziziritsira kachiwiri.
5. Ngati pachitika ngozi yolowera madzi m'dongosolo, chisamaliro chapadera chiyenera kuperekedwa pakuchotsa madziwo. Kuwonjezera pa kusintha mafuta oziziritsa, chisamaliro chapadera chiyenera kuperekedwa pakuzindikira acidity ya mafutawo, ndikusintha mafuta atsopano ndi fyuluta yowumitsa pakapita nthawi.
