Crankcase mpweya System: mitundu A chipangizo, mfundo opaleshoni

Pakali pano, ngakhale chitukuko mofulumira umisiri kulenga kwathunthu losindikizidwa awiri mbali mikangano - ndi yamphamvu ndipo pisitoni mphete - sikutheka. Choncho kudziunjikira mu ntchito kwa mankhwala a kuyaka mu injini.

The sump crankcase mpweya kudutsa mphete pisitoni, amene ali pafupi ndi zonenepa ndi mwachisawawa. Chifukwa, kutentha kuchotsedwa poipa adzafupikitsidwa moyo lubricating madzi likakhazikitsidwa komanso kuthamanga kwambiri pa onse chipika chisindikizo. crankcase dongosolo mpweya kumathandiza kwambiri crankcase kuthamanga.

chitukuko cha zipangizo

Kumayambiriro kwa limagwirira anali motere: kuchokera crankcase yosavuta mapeto chubu popanga mpweya m'mlengalenga ndi uwononge izo. Koma malamulo pa kumasulidwa mpweya ku magalimoto kwambiri omangika. Choncho, dongosolo crankcase mpweya anayamba kupanga internally ndi opanga.

Limagwirira mfundo kanthu

Mu mawonekedwe imene dongosolo amadziwika pa mphindi, mipweya osati ndi panamveka m'mlengalenga. Iwo wotumidwa kwa galimoto mwa chubu achoka sump ya chimaliziro ena amene chikugwirizana ndi zakudya zobwezedwa. Kuchokera kumeneko mpweya wa akuuzidwa m'chipinda kuyaka. Mfundo kung'anima wa iwo zopsereza ndi mbali ina amachoka kudzera limagwirira utsi. Only ndi chiwerengero ka mpweya awa kachiwiri akulowa crankcase. Popeza ndondomeko udzachitika mosalekeza.

Mitundu sump dongosolo recirculation

Pali mitundu iwiri ya kachitidwe:

• panja;
• chatsekedwa.

Mbali yoyamba, monga momwe tafotokozera poyamba paja, mpweya wa akatulutsidwa m'mlengalenga chabe. Wachiwiri iwo mawere mu zakudya ngalande. Chatsekedwa dongosolo crankcase mpweya: Vaz ndi "Lada", BMW ndi "Mercedes" Japan ndi ku America zimagwiritsa ntchito panopa.

Komanso, kachitidwe anatseka zilipo ndi AC kapena DC panopa. Yoyamba ndi angathe kulamulira molondola kwambiri recirculation sump. Izo zimasiyanasiyana malinga ndi kuchuluka kwa mpweya umene ukubwera.

chipangizo

Pamwamba pa olekanitsa ndi crankcase mpweya dongosolo ndipo mkati mafuta - ndi wonyezimiritsira. ntchito yake ndi kumasula mpweya kuchokera particles mafuta. PCV mafuta olekanitsa ali ndi kubwereketsa kuti ngalande za. Ntchito yachibadwa injini crankcase zonse zina zingalowe muzichita. vavu umagwira ntchito embodiments atatu.

Kukakamizidwa crankcase mpweya dongosolo: vavu

Tiyeni tikambirane mwachidule zonse zitatu zimene mungachite izi.

1. fulumizitsa ndi aumbike mwa mochedwerako 500 mpaka 700 mbar. crankcase dongosolo mpweya, ichi chidzachitika kuyima. Ndipo pisitoni pansi zochita za yosesa, atseka vavu.
2. Ngati fulumizitsa amadziwa lotseguka, kuthamanga uko ndi wofanana mumlengalenga kapena apamwamba. Akafike 500-700 mbar pisitoni atseka valavu kuti muyende mpweya.
3. Mu malo pakati amaperekedwa ndi kuthamanga pisitoni yachibadwa.

Ngati valavu ntchito zikutipatsa mafunso, n'zosavuta onani Kutukula. Kuti zimenezi zitheke, kusakhala ndi chochita pa khosi, wodzala ndi mafuta, kuika pepala. Ngati adatchithisira ndipo anauka ndi kayendedwe ka chifundamtima, vavu ndi ntchito.

uziyenda zimaikidwa kutsimikizidwa ndi njira zina. Mu mode chabe, kuchotsa payipi mpweya ndi kutseka chala ayenera kumva suction.

Anzanu kuchepetsa vavu

Ngati galimoto umagwira imathamanga kwambiri, madyedwe zobwezedwa kuthamanga ndi apo, kuti ali wofanana ndi mumlengalenga kapena kuposa izo. Mu nkhani iyi, crankcase mpweya afika yaitali. Ngati polowera ali turbocharger, zingalowe m'malo adzakhala waukulu kwambiri ndipo ayenera kukhala moyenera.

Kuti zimenezi zitheke, lili kufinya kuchepetsa valavu, amene umagwira ntchito zakudya zobwezedwa pamene vavu chikuyamba. Limagwirira wopangidwa mwa Kakhungu ndi kasupe ndi anaikapo mu nyumba pulasitiki, imene pali polowera ndi kubwereketsa zovekera.

Kuchuluka kwa ntchito kuchepetsa vavu

Mu yachibadwa otsika-kuthamanga kasupe ndi yodzaza. Kakhungu The liukitsidwa ndi mpweya ndi zapita momasuka.

Opanikizika yafupika, ndi zakulera ndi adatchithisira ndi kutseka kubwereketsa ndi kanthu masika. Ndiye mpweya anayamba adutsa kupatutsidwa kwa msewu wa - njira ndi kutsegula calibrated.

Mwatsoka, kumachita zabwino pa dzanja limodzi, dongosolo crankcase mpweya amalenga vuto ndi zina. Potuluka mphasa, mipweya ndi akugwidwa ndi lubricating particles, motero kuchotsako dongosolo wambiri. Ndiponso anakaika pa pamalo a mitsinje kuchoka, ndi mfundo za vavu akonzanso. Zimenezi zimabweretsa kuchepetsa wa njira ndi angayambitse malfunctions mu jekeseni wa. Ngati Iris ndi othinana, ndi mafuta kwambiri. Ndiye m'pofunika kusintha vavu.

Komanso musaiwale za zinthu zina zofunika, ndi nthawi kusintha payipi crankcase mpweya - Izi kawiri kawiri zimachitika molumikizana ndi mavavu recirculating. Apo ayi, ming'alu ndi yopuma.

Kupewa kukonza wapatali, m'pofunika kulabadira malo akutulukira pa zomatira injini, kuwonjezera kumwa utsi ndi lubricating madzimadzi ndi wosakhazikika ntchito injini. Ngati nthawi kuyendetsa kwa malo utumiki, vuto adzathetsedwa mu Mphukira, mpaka iye sanali kuwononga zogwirika kuti wagawo ndi.
