Mafuta umayenda kuchokera valavu chivundikirocho. Ikudontha mafuta - chochita

Engine kondomu dongosolo la kuyaka mkati ofanana ndi dongosolo anthu magazi. Mafuta, monga zikamamvekamveka magazi mu chatsekedwa kuzungulira, lubricating, kuzirala ndi kukonza mbali ikuyenda. Zonsezi, mwachibadwa, kukuchitika pansi wina kuthamanga, kuchepetsa kapena choposa cha zomwe akupatsidwa kuyambitsa kusokoneza mayendedwe a.

The kutayikira pang'ono mafuta injini - chizindikiro chakuti panali dongosolo depressurization. Ndipo ichi ndi chifukwa kwambiri kuganizira wozengereza diagnostics wa unit mphamvu.

M'nkhani ino tikambirana zifukwa pali, ndi mmene kukakonza kutayikira mafuta kuchokera pansi bonnet lapansi.

ndi valavu chivundikiro Kodi

mchitidwe uwu wa injini kuyaka mkati lakonzedwa kuteteza ku camshaft kuti anagundidwa ndi dothi, fumbi ndi chinyezi. Komanso, chivundikiro amateteza zonse nyumba danga la mafuta amene akudyetsedwa opanikizika kwa mafuta nthawi ya.

Woyamba injini kuyaka mkati analibe vavu chivundikiro, nchifukwa chake nthawi limagwirira zonse anali kusamba ndi woyera. M'kupita kwa nthawi zitsulo chivundikiro stamped ku lids woonda pepala zitsulo. Lero, chinthu ino aluminiyamu ndi akamaumba. Ndipo si monga chivindikiro, koma mamangidwe lonse, amene ali ndi ntchito ndi nthawi chitetezo, ndi kugwira nawo crankcase mpweya wabwino ndi mafuta zosonkhanitsira, utsi mbali yoyamikira limagwirira nthawi.

Pofuna zikayamba wa valavu lotsekera mutu yamphamvu kupyolera mphira kapena silikoni gasket. Magalimoto ena atsopano musaike PAD konse: udindo wake imagwiridwa ndi wosanjikiza wapadera wa sealant.

n'zotheka kutayikira

Ngati inu mungazindikire kuti mafuta umayenda kuchokera valavu chivundikiro, kuyesa kudziŵa kutayikira. Nthawi zambiri, ndi lubricant akhoza ikuyenda:

• mu mfundo za chivundikirocho ndi mutu yamphamvu chifukwa kuvala ziyangoyango kapena chipsyinjo owonjezera mu dongosolo;
• mu malo bolting chivundikiro ndi mutu yamphamvu;
• wa filler mafuta.

Nthawi zina, mafuta kutayikira ungachitike pa chivundikiro nyumba. Izi zikhoza kukhala chifukwa kuwonongeka kapena fakitale makina zopindika pa akuponya.

Monga tanenera kale, lubricant amazungulira kupyolera mu njira yapadera mu galimoto opanikizika opangidwa ndi mpope mafuta. The yachibadwa mafuta kuthamanga kwa aliyense injini ndi osiyana, izo zimatengera buku ake, nambala ya zonenepa, kuli nthambi, etc. Osati kuti ndikuganiza, kuyang'ana pa zolemba ntchito galimoto yanu, pali onse anasonyeza. Choncho, ngati kuthamanga dongosolo yafupika, izo chizindikiro kachipangizo yomweyo inu nyale loderako pa gulu chida. Koma ngati ndi kuwonjezeka ake, iye sanali anatani mwa njira iliyonse. M'mawu ena, kuthamanga zingadziŵike okha polumikiza kwa injini m'malo wapadera madzi sensa manometer. Kuganizira umboni wake, tinganene kuti mafuta umayenda kuchokera valavu chivundikiro chifukwa cha kuthamanga kuwonjezeka mu dongosolo, kapena chifukwa akadali mu gasket (zisindikizo).

Kodi mkulu mafuta kuthamanga

Galimoto, komanso kwa anthu, "kuthamanga magazi" Kodi sizikumuonekera bwino. Ifeyo, zimangosonyeza mavuto mu dongosolo kondomu. Choncho, ngati galimoto yanu mafuta chikuyenderera mwa valavu chivundikiro, ndipo amapezeka ndi kuchuluka kwa kuthamanga, chifukwa cha izi zikhoza kukhala:

• wonongeka chifukwa clogging wa crankcase mpweya mafuta olekanitsa grids;
• clogging mafuta yamphamvu mutu njira;
• clogging wa sefa mafuta;
• jamming kuthamanga kuchepetsa vavu mu malo chatsekedwa.

Tiyeni tione zinthu zimenezi mwatsatanetsatane, ndi ndondomeko imene bwino oterewa, ku zophweka kwambiri kwa zovuta ndi.

Wonongeka crankcase magawanidwe

Tiyeni tiyambe ndi zifukwa ambiri chifukwa amayamba kuthamanga mu dongosolo kondomu, kunachitika magalimoto zoweta. Nthawi zambiri, mafuta kuchokera pansi valavu chivundikiro Vaz akuyamba adzatsika chifukwa kuphwanya crankcase mpweya wabwino. Mwachidule, nkhonyayo-ndi mipweya, amene ayenera kukhala wopanda kuti utuluke mwa injini, kukumana ndi zopinga mu njira yake, ndi kuyamba kumanga mwake, kukonza overpressure. Mu nkhani iyi, osati amakankhira mafuta kuchokera valavu chivundikiro, koma akhoza kuponyera mwa breather mu mlengalenga fyuluta nyumba.

Kodi zingakhale kuti mavuto? Choyamba, olekanitsa gululi ngati yatsekera mankhwala kuyaka. Lachiwiri, madipoziti wamba ndi dothi pa makoma lamkati la nozzles, amene anagwirizana ndi hoses mpweya wabwino. Choncho ngati galimoto mafuta kuchokera pansi valavu chivundikiro galimoto yathu, osati aulesi kwambiri kuchotsa valavu chivundikirocho ndi kuyeretsa olekanitsa gululi, ndi imodzi kuyeretsa nozzles.

Yatsekera ndime mafuta ndi Zosefera

Mutu yamphamvu ali wapadera lonse zopezera njira imene chimachititsanso mafuta. Kugwiritsa ntchito mafuta otsika kalasi, dothi kulowa dongosolo, injini kutenthedwa - izi ndi zifukwa kwa njira awa akhale yatsekera. Zikatero, kuthamanga mafuta mwachibadwa kumawonjezera, chifukwa mpope mafuta ukupitirizabe kuthamanga.

Chinthu chomwecho chikuchitika pamene fyuluta yatsekera. Amalakatika angachithe, kulenga kuthamanga mu dongosolo. Ndipo palibe zodabwitsa mu chakuti mafuta umayenda kuchokera valavu chivundikiro, ngati inu kusintha sefa zaka zingapo zapitazo.

Vutoli likuchotsedwa ndi kuchotsa chinthu fyuluta ndi ankatenthetsa dongosolo ntchito madzi wapadera.

Wonongeka a kuthamanga kuchepetsa vavu

Nthawi zambiri, kuwonjezeka mafuta kuthamanga ndi zotsatira za vuto la kuthamanga kuchepetsa valavu wa mpope mafuta, chifukwa wake ndi nthawi. Chifukwa ambiri kulephera - jamming pamalo chatsekedwa, chifukwa cha zotsatira za limagwirira katundu mikangano (swarf) kapena dothi. Tayani vutoli ndi yosavuta. vavu mosavuta disassembled ndi kuyeretsa, koma dismantle mafuta mpope kuchita izi.

Kusankha vavu chivundikiro gasket

Samalani zokwanira kusankha gaskets, monga kuthetsa nthenda ya mafuta kuchokera pansi valavu chivundikirocho ndi ntchito otsika khalidwe mankhwala, ndinu chodziwikiratu kuti apambane. Zokonda ndi bwino kupereka mbali pachiyambi, kuzindikira kwake chiwerengero fakitale m'ndandanda. Ngati kapangidwe ndi mphira gasket, kuonetsetsa kuti mphira anali zofewa ndipo analibe akulimbana kapena latsala pang'ono kugwa. zopindika zonsezi kwenikweni bwanji zikayamba.

Kaya m'pofunika mafuta mphira gasket sealant

Nanga bwanji za kugwiritsa ntchito sealant zimango galimoto maganizo mogwirizana. Anthu ena amaganiza kuti tanthauzo lake inadmissible, pamene ena, m'malo mwake amanena kuti yekha n'zotheka kukwaniritsa chisindikizo wathunthu. Tiyeni tinene, ngati pamwamba pa chivundikiro ndi yamphamvu ali padziko roughness, ntchito sealant pa wokha, koma pokhapokha ngati amanena bwino wosanjikiza woonda. Ngati pamwamba mwangwiro limagwirizana, mungachite popanda izo, chifukwa zaka zingapo zapitazo, palibe aliyense kusindikiza si inawasangalatsa. Koma kwa galimoto, kumene unsembe sasamalira kamangidwe, popanda sealant sangachite.

Ngati mafuta umayenda kuchokera mkamwa kapena malo mgwirizano chamangiriridwa

Zimachitika kuti mafuta si zichokere pamphambano ya kali mating wa yamphamvu mutu ndi valavu chivundikiro, ndi Mwachitsanzo, ku filler mafuta kapena pamene pali kugwirizana chamangiriridwa. Chifukwa cha kuchucha awa ndi onse overpressure chomwecho. Kuchotsa zimayambitsa matenda oopsa, izo tikulimbikitsidwa kuti m'malo mphira gasket wa akapichi (ngati dongosolo lililonse), ndiponso kuti tione kuchucha mafuta filler kapu.

Malangizo

Potsiriza, ife kupereka ena nsonga kukuthandizani kupewa mavuto ndi ikudontha mafuta kapena mwamsanga kuthana nawo.

1. Panthawi yake m'malo mwa mafuta injini, ndi mafuta fyuluta.
2. Gwiritsani yekha apamwamba mafuta.
3. Musalole mafuta dothi, madzi ndi madzi ena ndondomeko.
4. Ndi ndime musaiwale kuti aletse kuthamanga mafuta mu dongosolo kondomu. Mu nkhani ya kuchuluka kwake, nthawi yomweyo akakonze magalimoto.
5. Pewani kutenthedwa injini.
6. Chongani ntchito a mayunitsi amachititsa crankcase mpweya wabwino.
7. Kusankha gasket kwa valavu chivundikiro, kupereka mmalo mankhwala pachiyambi.
8. Ikani sealant gasket woonda wosanjikiza mosalekeza. Pewani zinthu kukhudzana pa nthawi.
9. Kumanga valavu chivundikiro, osati-kumangitsa ndi akapichi.
10. Kupeza kutayikira mafuta kuchokera pansi valavu chivundikiro, musati kumangitsa ndi matenda ndi kukonza.
