Chosonkhanitsira zosefera - choyika mu poto yakutsogolo ya mafuta ya pampu yamafuta.
Chifukwa cha kukhuthala kwakukulu kwa mafuta okha komanso kuchuluka kwa zinyalala mu mafuta, kuti mafutawo azitha kusefedwa bwino, fyuluta yamafuta nthawi zambiri imakhala ndi magawo atatu, omwe ndi fyuluta yosonkhanitsira mafuta, fyuluta yopyapyala yamafuta ndi fyuluta yopyapyala yamafuta. Fyulutayo imayikidwa mu poto yamafuta patsogolo pa pampu yamafuta, ndipo nthawi zambiri imagwiritsa ntchito mtundu wa fyuluta yachitsulo.
Pofuna kuchepetsa kukana kukangana pakati pa ziwalo zoyenda mu injini ndikuchepetsa kutopa kwa ziwalozo, mafutawo amatumizidwa nthawi zonse kupita pamwamba pa kukangana kwa ziwalo zoyenda kuti apange filimu yamafuta opaka mafuta kuti azitha kudzola. Mafutawo ali ndi chingamu, zonyansa, chinyezi ndi zowonjezera zina. Nthawi yomweyo, panthawi yogwira ntchito ya injini, kuyika kwa zinyalala zachitsulo, kulowa kwa zinyalala mumlengalenga, komanso kupanga ma oxide amafuta kumapangitsa kuti zinyalala mu mafuta ziwonjezeke pang'onopang'ono. Ngati mafutawo sanasefedwe ndipo alowa mwachindunji mumsewu wamafuta opaka mafuta, adzabweretsa zinyalala zomwe zili mumafutawo pamwamba pa kukangana kwa zinyalala zoyenda, kufulumizitsa kutopa kwa ziwalo ndikuchepetsa moyo wautumiki wa injini. Ntchito ya fyuluta yamafuta ndikusefa zinyalala, chingamu ndi madzi mumafuta, ndikutumiza mafuta oyera ku ziwalo zopaka mafuta.
Fyuluta yamafuta okhuthala imayikidwa kumbuyo kwa pampu yamafuta, ndipo njira yayikulu yamafuta imayikidwa motsatizana, makamaka mtundu wachitsulo chotsukira, mtundu wapakati wa fyuluta ya utuchi, mtundu wa pepala losefera la microporous, makamaka pogwiritsa ntchito mtundu wa pepala losefera la microporous. Fyuluta yamafuta imayikidwa limodzi ndi njira yayikulu yamafuta pambuyo pa pampu yamafuta. Pali mitundu iwiri ya pepala losefera la microporous ndi mtundu wa rotor. Fyuluta yamafuta a rotor imagwiritsa ntchito kusefera kwa centrifugal popanda chinthu chosefera, zomwe zimathetsa bwino kutsutsana pakati pa kulowerera kwamafuta ndi magwiridwe antchito osefera.
Mitundu ya kuwonongeka kwa fyuluta ya mafuta ndi iyi makamaka:
1, fyuluta imaphimbidwa ndi mafuta, kapena fyulutayo yawonongeka.
2, kutsika kwa buoy kapena kusweka kwa nthaka, mafuta omwe ali mu buoy kapena fyuluta amaika kukula kwakukulu ndi kutsekeka komwe kumachitika chifukwa cha kuwonongeka.
3, payipi yatsekedwa; Chipangizo cholumikizira phazi sichili champhamvu ndipo chimagwa pambuyo pogwedezeka, zomwe zimapangitsa kuti cholumikizira chiwonongeke.
Fyuluta yamafuta imayikidwa patsogolo pa malo olowera mafuta a pampu yamafuta, ndipo ntchito yake yayikulu ndikuletsa zinyalala zazikulu zamakina kuti zisalowe mu pampu yamafuta yamakina a anthu. Fomu yosonkhanitsira fyuluta ikhoza kugawidwa m'ma fyuluta oyandama ndi fyuluta yokhazikika.
Kusankha ndi chosonkhanitsa zosefera
1. Ikani fyuluta
Chosonkhanitsira fyuluta nthawi zambiri chimapangidwa ndi chophimba chosefera ndipo chimakhala patsogolo pa pampu yamafuta kuti tinthu tating'onoting'ono tisalowe mu pampu yamafuta. Fyuluta yosonkhanitsira imagawidwa m'mitundu iwiri yoyandama komanso yokhazikika.
Fyuluta yoyandama imatha kuyamwa mafuta oyeretsera pamwamba, koma n'zosavuta kupumira thovu, zomwe zimapangitsa kuti mafuta azichepa komanso mafuta azithira osakhazikika. Fyuluta yokhazikika ili pansi pa mulingo wa mafuta, ngakhale kuti ukhondo wa mafuta opumirawo ndi woipa pang'ono kuposa wa mtundu woyandama, koma imapewa kuyamwa kwa thovu, mafutawo amakhala okhazikika, kapangidwe kake ndi kosavuta, ndipo injini yamagalimoto yapano imagwiritsa ntchito fyuluta yotere.
Chachiwiri, fyuluta yamafuta yodzaza ndi madzi
Fyuluta yamafuta yoyendera bwino imalumikizidwa motsatizana pakati pa pampu yamafuta ndi njira yayikulu yolowera mafuta kuti isefe mafuta onse. Pakadali pano, mainjini ambiri amagalimoto amagwiritsa ntchito zosefera zamafuta zoyendera bwino.
Mafyuluta amafuta oyenda bwino ali ndi mapangidwe osiyanasiyana a fyuluta, omwe mafyuluta apepala ndi omwe amapezeka kwambiri. Mafyuluta amafuta okhala ndi zinthu zosefera zapepala amagawidwa m'mitundu iwiri: ovunda ndi osakanikirana. Pamene chinthu chosefera chatsekedwa kwambiri ndi zinthu zosafunika, kuthamanga kwa mafuta pamalo olowera mafuta a fyuluta kumakwera, ndipo akafika pamtengo winawake, valavu yodutsa imatsegulidwa, ndipo mafutawo amalowa mwachindunji munjira yayikulu yamafuta popanda kusefa kudzera mu chinthu chosefera. Ngakhale kuti mafutawo amatumizidwa kuzinthu zosiyanasiyana zodzola popanda kusefa panthawiyi, ndi bwino kwambiri kuposa kusowa kwa mafuta odzola.
Zitatu, fyuluta yamafuta yogawanika
Magalimoto akuluakulu, makamaka injini za magalimoto akuluakulu, nthawi zambiri amagwiritsa ntchito zosefera zamafuta odzaza ndi madzi ndi shunt. Fyuluta yodzaza ndi madzi imayang'anira kusefa zinyalala zokhala ndi tinthu tating'onoting'ono toposa 0.05mm mumafuta, pomwe fyuluta ya shunt imayang'anira kusefa zinyalala zazing'ono zokhala ndi tinthu tating'onoting'ono tosakwana 0.001mm, ndipo 5% mpaka 10% yokha ya mafuta omwe amaperekedwa pampu yamafuta ndi omwe amasefedwa.
Fyuluta ya shunt type fine ili ndi mitundu iwiri: fyuluta ya filter ndi centrifugal. Pakadali pano, fyuluta ya centrifugal oil imagwiritsidwa ntchito kwambiri. Ili ndi rotor mkati yomwe imathandizidwa ndi ma bearing ozungulira. Pali nozzles ziwiri mu rotor, pogwiritsa ntchito mphamvu yogwira ntchito ya lubrication system yokha, mafuta akalowa mu rotor ndikutuluka mu nozzle, torque yobwerera imapangidwa, zomwe zimapangitsa rotor kuzungulira mwachangu. Pogwiritsa ntchito mphamvu ya centrifugal, zonyansa zolimba mu mafuta zimalekanitsidwa ndikusonkhanitsidwa pakhoma lamkati la rotor. Mafuta omwe ali pakati pa rotor amakhala oyera ndipo amatuluka kuchokera mu nozzle kubwerera ku poto yamafuta.
Four, fyuluta yamafuta a centrifugal
Fyuluta yamafuta ya centrifugal imadziwika ndi magwiridwe antchito okhazikika, kapangidwe kodalirika, palibe chifukwa chosinthira chinthu chosefera. Ingochotsani rotor nthawi zonse ndikutsuka banga pamwamba pa rotor, mutha kuigwiritsanso ntchito, ndipo nthawi yogwira ntchito ndi yayitali. Komabe, kapangidwe kake ndi kovuta, mtengo wake ndi wokwera, kulemera kwake ndi kwakukulu, ndipo zofunikira zaukadaulo kwa ogwira ntchito yokonza ndi zapamwamba.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zomwe zikulandiridwa kugula.
