Mafuta a compressor a Air amagwiritsidwa ntchito makamaka pakupaka mbali zosuntha za silinda ya kompresa ndi valavu yotulutsa mpweya, ndipo amatenga gawo la kupewa dzimbiri, kupewa dzimbiri, kusindikiza ndi kuziziritsa.
Chifukwa mpweya kompresa wakhala m'malo kuthamanga kwambiri, kutentha kwambiri ndi madzi condensate, mpweya kompresa mafuta ayenera kukhala abwino kwambiri kutentha makutidwe okosijeni bata, kutsika mpweya kudzikundikira chizolowezi, kukhuthala koyenera ndi viscosive-kutentha, ndi bwino mafuta-madzi kulekana. , kupewa dzimbiri komanso kukana dzimbiri
Zofunikira pamachitidwe
1. Mafuta apansi ayenera kukhala apamwamba
Mafuta oyambira amafuta a kompresa amatha kugawidwa m'magulu awiri: mtundu wamafuta amchere ndi mtundu wamafuta opangira.Kupanga mafuta amchere amchere amchere amchere amafuta nthawi zambiri amakhala kudzera pakuyenga zosungunulira, zosungunulira zosungunulira, hydrogenation kapena dongo lowonjezera kuti lipeze mafuta oyambira, kenako ndikuwonjezera zowonjezera zingapo kuti ziphatikizidwe.
Mafuta oyambira amafuta a kompresa nthawi zambiri amakhala opitilira 95% yamafuta omalizidwa, kotero kuti mtundu wamafuta oyambira umagwirizana mwachindunji ndi kuchuluka kwamafuta a compressor, ndipo mtundu wamafuta oyambira umakhala ndi ubale wachindunji. ndi kuya kwake kuyenga.Mafuta oyambira okhala ndi kuzama koyenga amakhala ndi zonunkhira zochepa komanso chingamu.Mpweya wotsalira ndi wochepa, mphamvu ya antioxidant ndi yabwino, khalidwe la mafuta apansi ndilokwera, limakhala ndi kachitidwe kakang'ono kamene kamadziunjikira carbon mu makina a compressor, kulekanitsa kwamadzi ndi madzi ndikwabwino, ndipo moyo wautumiki ndi wofanana. yaitali.
Mafuta opangira mafuta amtundu wamafuta ndi mafuta opaka mafuta opangidwa ndi organic liquid base mafuta otengedwa ndi kaphatikizidwe ka mankhwala kenako amasakanikirana kapena kuwonjezeredwa ndi zowonjezera zosiyanasiyana.Mafuta ake ambiri oyambira ndi ma polima kapena ma organic organic compounds.Pali mitundu yambiri yamafuta opangira, ndipo mafuta opangira omwe amagwiritsidwa ntchito ngati mafuta a kompresa makamaka amakhala ndi mitundu isanu ya hydrocarbon (polyalpha-olefin), organic ester (double ester), Snott lubricating oil, polyalkylene glycol, fluorosilicone mafuta ndi phosphate ester.Mtengo wamafuta opangira mafuta opangira mafuta ndi okwera mtengo kwambiri kuposa wamafuta amchere amchere, koma phindu lazachuma lamafuta opangira limaposa mafuta wamba amchere.Iwo ali makutidwe ndi okosijeni bata, chizolowezi yaing'ono mpweya kudzikundikira, akhoza kupitirira kutentha osiyanasiyana mafuta wamba mchere kwa kondomu, moyo wautali utumiki, akhoza kukumana ambiri mchere mafuta kompresa mafuta sangathe kupirira ntchito zofunika.
2. Tizigawo tating'ono ta mafuta
Kafukufuku wokhudza momwe mafuta a compressor amagwirira ntchito akuwonetsa kuti kuwongolera kapangidwe ka mafuta oyambira ndiye chinthu chofunikira kwambiri pakukweza mafuta a compressor.Mafuta a kompresa opangidwa ndi zinthu zopepuka komanso zolemetsa atalowetsedwa mu silinda ya kompresa, zowunikira zimasiya gawo logwira ntchito pasadakhale chifukwa chakusakhazikika kwakukulu, komwe kumakhudza mphamvu yamafuta, ndipo zigawo zophatikizanso sizingachoke mwachangu pagawo logwira ntchito mukamaliza. ntchito ntchito chifukwa chosakhazikika bwino, ndipo n'zosavuta kupanga madipoziti mpweya pansi zochita za kutentha ndi mpweya kwa nthawi yaitali.Choncho, pansi pazifukwa zotere, mafuta odzola ayenera kusankhidwa ngati kachigawo kakang'ono ka gawo la mafuta, ndipo sayenera kusankhidwa ngati chisakanizo cha zigawo zambiri za chigawocho mafuta.
No. 19 mafuta kompresa amapangidwa ndi mafuta ambiri a distillate okhala ndi zigawo zambiri zotsalira, ndipo kuchuluka kwa kaboni komwe kamasonkhanitsidwa mu kompresa ndikokulirapo.Choncho, pofuna kupititsa patsogolo ubwino wa mafuta a compressor, zigawo zotsalira za mafuta a compressor nambala 19 ziyenera kuchotsedwa ndipo mafuta ochepa a distillate ayenera kusankhidwa.
3. Kukhuthala kumayenera kukhala koyenera
Pansi pa kudzoza kosunthika, makulidwe a filimu yamafuta amawonjezeka ndi kuchuluka kwa kukhuthala kwamafuta, koma kukangana kumawonjezeka ndi kuchuluka kwa kukhuthala kwamafuta.Mafuta odzola okhala ndi mamasukidwe otsika kwambiri sizovuta kupanga filimu yokwanira yamafuta, yomwe imathandizira kuvala ndikufupikitsa moyo wautumiki wa magawowo.M'malo mwake, kukhuthala kwa mafuta odzola ndikokwera kwambiri, komwe kumawonjezera kukangana kwamkati, kuonjezera mphamvu yeniyeni ya kompresa, zomwe zimapangitsa kuti magetsi azichulukirachulukira komanso kuwononga mafuta, komanso kupanga ma depositi mu piston ring groove, mpweya. valve, ndi exhaust channel.Choncho, kusankha mamasukidwe oyenera ndilo vuto lalikulu la kusankha koyenera kwa mafuta a compressor.Xi 'an Jiaotong University yatsimikizira kudzera mu mayeso kuti: pogwiritsa ntchito mayeso omwewo pamtundu womwewo wa kompresa, kugwiritsa ntchito mafuta otsika kukhuthala kwamafuta kuposa kugwiritsa ntchito magiredi apamwamba kwambiri amafuta kumatha kuchepetsa mphamvu yeniyeni ya kompresa pafupifupi 10% nthawi zambiri, ndipo kuchuluka kwa magawo sikusiyana kwambiri.Chifukwa chake, poyang'anira kuonetsetsa kuti mafuta amafuta, kusankha kwamafuta oyenera kukhudzika kwamafuta kumakhudza kwambiri kupulumutsa mphamvu komanso magwiridwe antchito odalirika a compressor.
