Ntchito ndi Kukonza kwa Dizilo Engine Crankcase Breathing Pipe
2021-07-29
Ma injini a dizilo amakhala ndi mapaipi olowera mpweya wa crankcase, omwe amadziwika kuti ma respirators kapena ma venti, omwe amatha kupangitsa kuti pabowo la crankcase azilumikizana ndi mlengalenga, kuchepetsa kugwiritsa ntchito mafuta, kuchepetsa kulephera, ndikuwonetsetsa kugwira ntchito bwino. Pamene injini ikugwira ntchito, gasi mu silinda idzatuluka mu crankcase, ndipo kutayikira kwa silinda, pistoni, mphete ya pistoni ndi mbali zina kumakhala koopsa kwambiri pambuyo pa kuvala. Gasi akalowa mu crankcase, kuthamanga kwa gasi mu crankcase kumawonjezeka, zomwe zimapangitsa kuti mafuta atuluke pamtunda wa injini ndi poto yamafuta ndi bowo la geji yamafuta. Kuonjezera apo, mpweya wotayira uli ndi sulfure dioxide, ndipo kutentha ndi kwakukulu, zomwe zidzafulumizitsa kuwonongeka kwa injini ya mafuta. Makamaka mu injini ya silinda imodzi, pisitoni ikatsika, mpweya mu crankcase umaponderezedwa, zomwe zimayambitsa kukana kuyenda kwa pisitoni.

Choncho, ntchito ya crankcase breather chitoliro akhoza mwachidule monga: kuteteza injini kuwonongeka mafuta; kupewa kutayikira kwa crankshaft mafuta seal ndi crankcase gasket; kuteteza ziwalo za thupi kuti zisachite dzimbiri; kuletsa nthunzi zosiyanasiyana zamafuta kuti zisawononge mpweya. Pogwiritsidwa ntchito kwenikweni, n'zosapeŵeka kuti chitoliro cha mpweya wabwino chidzatsekedwa. Kuti musatseke, pafunika kukonzanso nthawi zonse. M'malo ogwirira ntchito, 100h iliyonse ikhoza kukhala yozungulira; kugwira ntchito m'malo ovuta omwe ali ndi fumbi lambiri mumlengalenga, nthawi yokonza iyenera kukhala 8-10h.

Njira zokonzetsera zenizeni ndi izi: (1) Yang'anani payipi ngati ikuphwanyidwa, kuwonongeka, kutayikira, ndi zina zotero, ndiyeno muyeretseni ndi kuliphulitsa ndi mpweya woponderezedwa. (2) Pa chipangizo cholowera mpweya cha crankcase chokhala ndi valavu yanjira imodzi, ndikofunikira kuyang'ana pakuwunika. Ngati valavu yanjira imodzi yatsekeredwa ndipo siinatsegulidwe kapena kutsekedwa, mpweya wabwino wa crankcase sungakhale wotsimikizika ndipo uyenera kutsukidwa. (3) Chongani vacuum ya vavu. Chotsani valavu yanjira imodzi pa injini, kenaka gwirizanitsani payipi ya mpweya wabwino, ndikuyendetsa injiniyo mofulumira. Ikani chala chanu pamapeto otseguka a valve ya njira imodzi. Panthawi imeneyi, chala chanu chiyenera kumva vacuum. Ngati mukweza chala chanu, khomo la valve liyenera kukhala ndi phokoso la "Pop "Pap"; ngati palibe phokoso kapena phokoso pa zala zanu, muyenera kuyeretsa valavu ya njira imodzi ndi payipi yolowera.
