Mafuta omwe amagwiritsidwa ntchito popanga zigawo zosuntha mu compressorr amatchedwa mafuta firiji, omwe amadziwikanso mafuta owuma. Malinga ndi miyezo yautumiki wamakampani a Perochemical, pali mitundu isanu ya firiji yopangidwa ku China, yomwe, No. 13, Ayi. 25, Ayi. 25, Ayi. 25, Ayi. 25, Ayi. 25, Ayi. 25, Ayi. Pakati pawo, comprester compressor mafuta ophika mafuta adziko lapansi. 13, No. 18 ndi Na. 25, R12 Compressors nthawi zambiri amasankha Ayi. 18, R22
Mu compressor, mafuta firiji makamaka mafuta, kusindikiza, kuwongolera ndi mphamvu ya maudindo anayi.
(1)
Mafuta a firiji pakuchita compressor mafuta, kuti achepetse kuchuluka kwa compressiction, potero ndikuwonjezera moyo wa compressor.
(2) Kusindikiza
Mafuta firiji amadya compresser, kuti compressor piston ndi cylinder pamwamba, pakati pa zosemphana ndi firiji kuti mukwaniritse izi.
(3) Kuzizira
Mukakhala ndi mafuta pakati pa zipsinjo yosunthika ya compressor, mafuta mu firient amatha kuchotsa kutentha komwe kumapangidwa panthawi yogwira ntchito, kotero kuti madera osunthira akukhalabe ndi kutentha pang'ono, motero kumawongolera mphamvu ndi kudalirika kwa compresser.
(4) Mphamvu zamphamvu
Kwa compressishir compresyar yokhala ndi njira zamagetsi, zitha kugwiritsa ntchito kuthamanga kwa mafuta kwa firiji ngati mphamvu ya makina a mphamvu zamakina.
Choyamba, ndizofunikira bwanji za zida fifiketi pa kuphika kwa firiji
Chifukwa cha kugwiritsa ntchito nthawi zosiyanasiyana komanso kufinya, zida firiji pakusankha kuti mafuta firiji sichofanana. Zofunikira za mafuta firiji kukhala ndi izi:
1, mafayilo
Kufinya kwa Mafuta a Vific Cuscle Mapangidwe a gawo lofunikira, kugwiritsa ntchito mitundu yosiyanasiyana kusankha mafuta osiyanasiyana firiji. Ngati mafayilo a mafuta firiji ndi akulu kwambiri, mphamvu yamatsenga, kutentha kwa miseche komanso kuyambitsa torque. M'malo mwake, ngati mamasukidwewo ndi ochepa kwambiri, imapangitsa kuti kuyenda pakati pa magawo sikungapangire filimu yofunikira, kuti musakwaniritse mafuta ofunikira komanso ozizira.
2, Turbidity Point
Kutalika kwa Mafuta firiji ndi kutentha kumachepetsedwa kukhala mtengo winawake, mafuta firiji anayamba kuyendetsa parafini, kuti mafuta opangira mafuta amasandulika kutentha. Zipangizo za firiji zomwe zimagwiritsidwa ntchito pakuwononga mafuta kuyenera kukhala kotsika kuposa kutentha kwa mufiriji, apo ayi kumayambitsa ma vanve vungwe kapena kusokoneza magwiridwe antchito.
3, malo olimbika
Mafuta a mufirifient mu zoyeserera zozizira kuti aletse kutentha kwa kutentha kwa kutentha kodziwika bwino. Zida fificeji zomwe zimagwiritsidwa ntchito pakuzizira kwa mafuta ku firiji ziyenera kukhala zochepa momwe zingakhalire (monga R22 Compressor, Mafuta firiji ayenera kukhala pansi -55℃) Kupanda kutero kusokoneza mayendedwe a firiji, kuwonjezereka kukana, kumapangitsa kusamutsa kutentha.
4, Flash point
Mafuta a firiji Zida zogwirizira℃kapena kupitirira apo, kuti musayambitse kuyamwa ndikuphika mafuta odzola.
5, kukhazikika kwa mankhwala ndi kukana kwa oxygen
Kupangidwa koyera kwamafuta ndi khola, osati oxidation, sadzang'amba zitsulo. Komabe, mafuta atakhala ndi firiji kapena madzi zipatso zimamera kutchire, mafuta oxidation amapanga asidi, kuwononga zitsulo. Pamene mafuta amafuta kutentha kwambiri, padzakhala cowu, ngati mfundoyi yolumikizidwa ndi mbale ya valavu, idzakhudzanso ntchito ya valavu ya valavu, nthawi yomweyo idzayambitsa zosefera ndi zotupa. Chifukwa chake, ziyenera kusankhidwa ndi kukhazikika kwa mankhwala ndi maxidation kukana kwa oxida ndi zabwino zamagetsi.
6, chinyezi komanso zolakwika zamakina
Ngati mafuta opangira mafuta ali ndi madzi, adzachulukitsa kusintha kwa mankhwala mu mafuta, kotero kuti mafuta amawonongera, komanso valavu yamphamvu kapena yowonjezera. Mafuta owoneka bwino amakhala ndi zonyansa zamakina, ndipo posachedwapatsetsetsani zosefera ndi valavu ya valavu ya valavu kapena magetsi owonjezera, motero mafuta odzola mafuta sayenera kukhala ndi zosayera.
7, kulingalira
Mu gawo lotsekedwa ndi mafuta ouluka kwathunthu, oundana ozizira ndi mphepete mwa zomangamanga ndi kuwomba kwagalimoto ndi kulumikizana kwamphamvu, motero kufunikira mafuta kukhala ndi malo abwino okhala ndi mabwinja okwezeka kwambiri. Masewera oyera amafuta onunkhira ndi abwino, koma amakhala ndi madzi, zosayera ndi fumbi, ntchito yake imachepetsedwa, zofuna zake za kusokonekera kwa mafuta am'madzi a 2,5kv kapena kupitilira apo.
8, chifukwa cha mikhalidwe yosiyanasiyana ya kufilirika ndi zosiyana, kutentha kwa dongosolo la firiji kumasiyanasiyana mosiyanasiyana, mafuta otsika, kutentha kwambiri kwa zida firiji, malo ozizira kwambiri. Ndipo zothamanga-kuthamanga kapena zowongolera mpweya zida za firiji ziyenera kusankhidwa mafayilo, kuzizira kwa mafuta okwanira.
二, Kutanthauzira kugwiritsa ntchito compresyar firiji ya firiji
1. Mafuta omwe siakonzedweratu
2. HFC-134a (R-134a) imafotokoza kuti mafuta firiji itha kuyamwa chinyezi mwachangu kuchokera mlengalenga. Chonde tsatirani izi:
.
. Chonde lombani zigawo za firiji posachedwa kuti muchepetse chinyezi mlengalenga.
(3) Mafuta osungidwa osungidwa okhala m'matumba osindikizidwa angagwiritsidwe ntchito. Pambuyo pa ntchito, chonde sinikizani chidebe cha mafuta. Ngati mafuta sasindikizidwa bwino, sangagwiritsidwenso ntchito atayikidwa ndi chinyontho.
3. Osagwiritsa ntchito mafuta owonongeka ndi firiji ya firient, chifukwa zimakhudzanso kupanikizana kwa compressor.
4. Dongosolo liyenera kuthandizira mafuta mufiriji malinga ndi kuchuluka kwa Mlingo. Ngati mafuta a firient ndi otsika kwambiri, zimakhudza mafuta opanga compresser. Kuonjezera mafuta okwera kwambiri kudzakhudzanso kuzizira kwa makina owongolera mpweya.
5. Powonjezeranso firiji, mafuta firiji ayenera kuwonjezedwa koyamba, kenako firiji iyenera kuwonjezeredwa
