Zomwe Zimayambitsa ndi Njira Zothetsera Kupanikizika Kwambiri kwa Mafuta a Injini ya Dizilo

1. Kuthamanga kwamafuta ndikokwera kwambiri

Kuthamanga kwamafuta kwambiri kumatanthauza kuti chiwongola dzanja chamafuta chimaposa mtengo womwe watchulidwa.

1.1 Chida chowonetsera kupanikizika kwamafuta sichachilendo

Sensor ya kuthamanga kwamafuta kapena choyezera chamafuta ndi chosazolowereka, kupanikizika kwamafuta sikolondola, mtengo wowonetsera ndi wokwera kwambiri, ndipo kuthamanga kwamafuta kumawonedwa molakwika kuti ndikokwera kwambiri.Gwiritsani ntchito njira yosinthira (mwachitsanzo, m'malo mwa sensa yakale ndi choyezera kuthamanga ndi sensor yabwino yamafuta ndi choyezera kuthamanga).Yang'anani kachipangizo katsopano ka mafuta ndi mphamvu yamafuta.Ngati chiwonetserocho ndichabwinobwino, chikuwonetsa kuti chipangizo chakale chowonera ndi cholakwika ndipo chiyenera kusinthidwa.

1.2 Kukhuthala kwakukulu kwamafuta

Kukhuthala kwa mafuta ndi kwakukulu kwambiri, madzi amadzimadzi amakhala osauka, kukana kwamafuta kumawonjezeka, ndipo kuthamanga kwa mafuta kumawonjezeka.Ngati m'chilimwe, mafuta amasankhidwa omwe amagwiritsidwa ntchito m'nyengo yozizira, kuthamanga kwa mafuta kumawonjezeka chifukwa cha kukhuthala kwakukulu.M'nyengo yozizira, chifukwa cha kutentha kochepa, kukhuthala kwa mafuta kumawonjezeka, ndipo kupanikizika kudzakhala kokwera kwambiri panthawi yochepa poyambitsa injini.Komabe, pambuyo pa ntchito yokhazikika, pang'onopang'ono imabwereranso ku mtengo wotchulidwa ndi kukwera kwa kutentha.Pakukonza, mtundu wamafuta a injini udzasankhidwa malinga ndi zofunikira zaukadaulo;Njira zotenthetsera ziyenera kuchitidwa poyambitsa injini m'nyengo yozizira.

1.3 Chilolezo cha gawo lopaka mafuta ndilaling'ono kwambiri kapena fyuluta yachiwiri yamafuta yatsekedwa

Chilolezo chofananira cha magawo opangira mafuta, monga kunyamula cam, kulumikiza ndodo, crankshaft yayikulu ndi rocker arm bearing, ndizochepa kwambiri, ndipo gawo lazosefera lasefa yachiwiri latsekedwa, zomwe zimawonjezera kukana komanso kupanikizika kwamafuta. kuzungulira kwa lubrication system.

Kuthamanga kwa mafuta a injini pambuyo pa kukonzanso kumakhala kwakukulu kwambiri, zomwe nthawi zambiri zimakhala chifukwa cha kutsika kochepa kwa chitsamba (chobala chitsamba) pa gawo lopaka mafuta.Kuthamanga kwamafuta a injini komwe kwagwiritsidwa ntchito kwa nthawi yayitali ndikokwera kwambiri, komwe kumachitika chifukwa cha kutsekeka kwa fyuluta yabwino yamafuta.Iyenera kutsukidwa kapena kusinthidwa.

1.4 Kusintha kosayenera kwa valve yoletsa kuthamanga

Kuthamanga kwa mafuta kumadalira mphamvu ya masika a valve yoletsa kupanikizika.Ngati mphamvu yamasika yosinthidwa ndi yayikulu kwambiri, kupanikizika mumayendedwe opaka mafuta kumawonjezeka.Konzani mphamvu ya kasupe ya valavu yoletsa kuthamanga kuti mafuta abwererenso pamtengo womwe watchulidwa.

2. Kuthamanga kwa mafuta kumakhala kochepa kwambiri

Kuthamanga kwamafuta otsika kumatanthauza kuti kuwonetsera kwa gauge yamafuta ndikotsika kuposa mtengo womwe watchulidwa.

2.1 Pampu yamafuta imavalidwa kapena gasket yosindikiza yawonongeka

Kutuluka kwamkati kwa zida zamkati za pampu yamafuta kumawonjezeka chifukwa cha kuvala, zomwe zimapangitsa kuti mafuta azikhala ochepa kwambiri;Ngati gasket yomwe ili pamagulu osonkhanitsa fyuluta ndi pampu ya mafuta yawonongeka, kuyamwa kwa mafuta a pampu ya mafuta sikukwanira ndipo kuthamanga kwa mafuta kumachepetsedwa.Panthawiyi, yang'anani ndikukonza mpope wamafuta ndikusintha gasket.

2.2 Kuchepetsa kuchuluka kwa mafuta a pampu yoyamwa

Ngati kuchuluka kwa mafuta mu poto yamafuta kuchepetsedwa kapena kutsekeka kwa pampu yamafuta kutsekedwa, kuyamwa kwamafuta a pampu yamafuta kumachepetsedwa, zomwe zimapangitsa kuchepa kwa kuthamanga kwamafuta.Panthawiyi, yang'anani kuchuluka kwa mafuta, onjezerani mafuta ndikuyeretsa chojambulira chopopera mafuta.

2.3 Kutaya kwakukulu kwamafuta

Pali kutayikira mu payipi ya mafuta dongosolo.Chifukwa cha kuvala komanso kuvomerezeka kokwanira pa crankshaft kapena camshaft, kutayikira kwa makina opaka mafuta kumawonjezeka ndipo kupanikizika kwamafuta kumachepa.Panthawiyi, fufuzani ngati payipi ya kondomu yathyoledwa, ndipo fufuzani ndikusintha chilolezo choyenerera cha mayendedwe pa crankshaft ndi camshaft ngati mukufunikira.

2.4 Zosefera zotsekedwa zamafuta kapena zoziziritsa kukhosi

Ndi kukulitsa nthawi ya ntchito ya fyuluta yamafuta ndi kuziziritsa, zonyansa zamakina ndi kuwonjezeka kwa dothi, zomwe zingachepetse gawo lakuyenda kwamafuta, kapena kutsekereza fyuluta ndi kuziziritsa, zomwe zimapangitsa kutsika kwamafuta pagawo lopaka mafuta.Panthawi imeneyi, yang'anani ndi kuyeretsa mafuta fyuluta ndi ozizira.

2.6 Kusintha kolakwika kwa valve yoletsa kuthamanga

Ngati mphamvu ya kasupe ya valve yochepetsera mphamvu ndi yaying'ono kwambiri kapena mphamvu ya masika imasweka chifukwa cha kutopa, mphamvu ya mafuta imakhala yochepa kwambiri;Ngati valavu yoletsa kupanikizika (yomwe imakhudzidwa ndi zonyansa zamakina) siyikutsekedwa mwamphamvu, kuthamanga kwamafuta kumatsikanso.Panthawiyi, yeretsani valavu yoletsa kuthamanga ndikusintha kapena kusintha kasupe.

3. Palibe kuthamanga kwa mafuta

Palibe kukakamiza kumatanthauza kuti 0.

3.1 Mulingo wa kuthamanga kwamafuta wawonongeka kapena payipi yamafuta yasweka

Masuleni chitoliro chophatikizana ndi choyezera kuthamanga kwa mafuta.Ngati mafuta akuthamanga atuluka, chiwongola dzanja chamafuta chimawonongeka.M'malo mwake choyezera kuthamanga.Kuchulukirachulukira kwamafuta chifukwa cha kuphulika kwa payipi yamafuta sikungayambitsenso kupanikizika kwamafuta.Paipi yamafuta iyenera kusinthidwa.

3.3 Kuwonongeka kwa pampu yamafuta

Pampu yamafuta ilibe mphamvu yamafuta chifukwa chakuvala kwambiri.Konzani pompa mafuta.

3.4 Pepala losefera mafuta limayikidwa mobweza

Mukakonzanso injini, ngati simusamala, ndikosavuta kuyika pepalalo pamalumikizidwe pakati pa fyuluta yamafuta ndi cylinder block, ndipo bowo lolowera mafuta limalumikizidwa ndi dzenje lobwerera mafuta.Mafuta sangalowe mumsewu waukulu wamafuta, zomwe zimapangitsa kuti pasakhale mafuta.Ikaninso pepala la pepala la fyuluta yamafuta.
