Dongosolo lopaka mafuta ndiye chinsinsi chamitundu yonse yamakina ndi zida, zida zamagalimoto, imodzi mwamagawo ofunikira pakukonza sikulowa mu zonyansa.
Nthawi zambiri timatchera khutu ku fumbi, zonyansa za particulate, zowononga madzi, nthawi zambiri timanyalanyaza mpweya.
Mpweya umakhudza magwiridwe antchito amafuta opaka mafuta, pomwe mafuta amalumikizana mosalephera ndi mpweya, koma mumafuta opaka mafuta osakanizidwa ndi mpweya, monga mafuta sangatulutsidwe mkati mwa thovu, kuwira kwamafuta, zotsatira zoyipa zamafuta.
Nthawi zambiri, mafuta opaka mafuta amakhala pang'onopang'ono akakumana ndi okosijeni wa mpweya (
Kulumikizana ndi oxygen)
, koma ndondomeko ndi pang'onopang'ono, nawonso ndi yosapeweka, yachibadwa, koma ngati mpweya mkati mafuta mafuta, vuto ndi lalikulu.
mu mafuta opaka osakaniza ndi mpweya pali mitundu itatu ikuluikulu: mpweya wosungunuka mu mafuta (
Wosawoneka ndi maso)
, kuyimitsidwa, kutsekeredwa mkati mwa mafuta sikungatulutse thovu la gasi, kuwira kwamafuta.
Pakati pawo, makinawo adayimitsidwa, mafuta owopsa kwambiri komanso opaka mafuta adakhazikika mumafuta mkati mwa kuwira.
kuwira kumasonkhana, kuyandama pamwamba pa mafuta, voliyumu yayikulu, ngati pali thovu, chenjerani ndi mafuta mkati mwake nthawi zambiri amakhala ndi thovu.
Bubble imayimitsidwa, yotsekeredwa mkati mwa mafuta, voliyumuyo ndi yaying'ono, koma yovulaza kwambiri.
Mpweya thovu adzachititsa turbidity mafuta, ngati turbidity mafuta si bwino, akhoza kutenga chitsanzo, ngati pali hierarchical, kotero kuipitsidwa mafuta mafuta ndi turbid madzi kapena zakumwa zina.
Ngati mulole kuyimirira kwa nthawi, chitsanzo kubwezeretsa bwino, mafuta wothira mpweya thovu.
chifukwa cha mafuta odzola ali ndi thovu mkati
zifukwa zambiri zidzachititsa kuwira, kuwira mu kuchuluka kwa mafuta, mmodzi wa ambiri ndi mu lubricating mafuta m'madzi.
Pamene wothira madzi mu mafuta, akhoza kuchepetsa mavuto padziko mafuta, sakanakhoza kupanga thovu lalikulu tiwolokere pamwamba, koma losweka mu thovu yaing'ono imaimitsidwa mu mafuta mkati.
Kuipitsa mafuta opaka: mafuta osakaniza ndi madzi ena, zotsukira, zosungunulira ndi zinthu zina.
mafuta oxidation oxidation: mafuta oxidation adayambitsa kukana kwa kuwira kwamafuta kuchepetsedwa, mafuta ena akagwiritsidwa ntchito pakapita nthawi yayitali pamakhala kuwira kowonjezereka, chifukwa chodziwika bwino ndichifukwa choti okosijeni wamafuta.
zowonjezera wotopa, odana ndi thovu wothandizira kutaya kungachititse thovu kuwonjezeka, ayenera kulabadira mfundo imodzi: antifoaming wothandizila anawonjezera kwambiri akhoza kuoneka kuwira vuto.
Ogwiritsa ntchito ena amawona kuwira kukuchulukirachulukira kapena antifoaming wothandizira adyedwa, amatha kuwonjezera, anti-thovu wothandizira, anti-foam wothandizira wowonjezera amatha kuyambitsa thovu.
kutayikira: chubu, kutayikira m'malo monga chisindikizo.
thanki yopangidwa molakwika: thanki yamafuta ndi yaying'ono kwambiri, osawonjezera mauna osefera, baffle, kubwerera ku chubu lamafuta ndi chubu kuli pafupi kwambiri, kuthamanga kwachangu kutulutsa thovu mochedwa.
mu kuwira mafuta kuwira, kuwira kwa zoopsa za
thovu ndi thovu zimakhala zovulaza pamafuta opaka mafuta ndi makina, kuwira kumafulumizitsa makutidwe ndi okosijeni amafuta opaka mafuta, kufulumizitsa kugwiritsa ntchito zowonjezera, filimu yamafuta yotentha, sikungapange kuwonongeka kwathunthu, kuwonongeka kwa zida ndi kung'ambika.
Miyendo yothamanga kwambiri imayambitsa kutentha kwapafupipafupi, mafuta amasintha mofulumira.
kuwonongeka kwa zida:
zosavuta compress mpweya, mafuta mafuta, pali mpweya, mafuta filimu makulidwe amakhala woonda ndipo ngakhale mafuta filimu anang'ambika ndi mikangano mwachindunji pakati pa makina zigawo zikuluzikulu, kuchititsa kung'ambika.
chifukwa cavitation: kuwira kuphulika mopanikizika, cavitation kuwonongeka pa zitsulo pamwamba mapangidwe.
kukhudza makina ntchito: kuwira zidzakhudza ntchito khola dongosolo makina, monga hayidiroliki dongosolo adzakhala wosakhazikika ntchito, kanthu ndi kunja kwa ulamuliro, dzimbiri, utoto filimu aumbike pa valavu pachimake kupanikizana ndi zina zotero.
pamene kuwira chinawonjezeka mu thanki, kodi kuchita?
ntchito woyera, youma, zitsanzo kuchokera kumaliseche mafuta botolo pakamwa kutenga chitsanzo, penyani ngati pali madzi mu mafuta & ndash;
-
Madzi aulere kapena mafuta otsekemera, osanjikiza, otumbululuka otumbululuka.
Ngati pali madzi, kuwiraku kumachitika chifukwa cha mafuta opaka m'madzi.
ngati sichinayambike chifukwa cha chinyezi, ndi malo owonetsetsa kuti mafuta akutuluka, ngati zonse zili bwino, ziyenera kupanga mafuta oyesa kuyesa mafuta, kuyesa ngati aipitsidwa ndi mankhwala ena kapena mafuta, kapena kugwiritsa ntchito zowonjezera, mafuta a metamorphism.
ngati thanki silinapangidwe bwino, lingaganizire kuwonjezera voliyumu, mu thanki yamafuta ndi kuyamwa kwamafuta onjezerani baffle, mauna.
ofunda mwamsanga: kuonetsetsa kwambiri makina kondomu, ayenera kupewa mu zinthu zina zilizonse ndi mafuta mu mafuta mafuta, mafuta ayenera kukhala oyera, youma, wopanda kuipitsidwa zina zakuthupi.
