1. Mafuta osagawanika omwe amayamba chifukwa cha kulephera kwamakina: Pambuyo pakugwiritsa ntchito nthawi yayitali, chifukwa cha mipata yotayirira kapena yayikulu kwambiri pakulumikiza kwa pampu ya jekeseni wamafuta, zida zamagalimoto zawonongeka ndikuwonjezeka kwakumbuyo, komwe kudzakhudzenso kufanana kwa kupezeka kwa mafuta kwa silinda iliyonse. Kuphatikiza apo, kutayikira kwa mapanipi amafuta othamanga kwambiri chifukwa chamanjenjemera pafupipafupi kapena osakwanira, komanso kulimbitsa kwambiri mphamvu kumatha kupangitsa kuti cholumikizira chachitsulo chigwe ndikuletsa mapaipi amafuta, zomwe zimapangitsanso kupezeka kwamafuta osagwirizana mu silinda iliyonse. Kuphatikiza apo, pakati pa mapampu opangira mafuta ndi akasupe a kazembe, akasupe olowera ndi omwe amakhala ndi mphamvu zamphamvu, mapindikidwe akulu, komanso pafupipafupi ogwira ntchito. Chifukwa chake pafupipafupi kuthyolanso kulinso kwakukulu. Mphamvu ya jekeseni wamafuta yocheperako yafupika, kuchuluka kwa jekeseni wamafuta yamphamvu iliyonse sikufanana, nthawi ya jekeseni wamafuta yamphamvu iliyonse siyatha, ndipo nthawi yoyambira jekeseni wamafuta yachedwa; mafuta olemera amakhala apakatikati kapena osakwanitsa kupereka.

Mafuta osagawanika nthawi yolakwika: Pampu ya jekeseni wamafuta ikawonongedwa pa benchi yoyeserera, kufanana kwa mafuta amtundu uliwonse pamagetsi oyerekeza kuyenera kukhala 3%.

3.Kusiyanitsa pakati pamagetsi okhathamira ndi momwe amagwiritsidwira ntchito: mpope wa jekeseni wamafuta umachotsedwa pa benchi yoyeserera kutentha kwapakati, pomwe ntchito yomwe imagwiritsidwa ntchito imagwiritsidwa ntchito pomwe cholembedwacho chikukakamizidwa, kutentha kwake kumafika 500 ～ 700 ℃, ndi kuthamanga ndi 3 ～ 5MPa. , Awiriwa ndi osiyana kwambiri. Makina oyendetsa njanjiwo akamagwira ntchito, kutentha kwa mpope wa jakisoni wamafuta ndi chopangira mafuta kumafikira pafupifupi 90 ° C, zomwe zimapangitsanso kukhuthala kwa dizilo kuchepa. Chifukwa chake, kutayikira kwamkati kwa plunger ndi msonkhano wamagetsi wa singano kumawonjezeka, ndipo kuchuluka kwamafuta kubwerera ndikochulukirapo kuposa nthawi yolakwika. Malinga ndi muyeso, kuchuluka kwenikweni kwa mafuta obayidwa mu silinda ndi pampu ya jekeseni wamafuta kumangokhala pafupifupi 80% ya benchi yoyeserera yoyeserera voliyumu. Ngakhale ogwira ntchito pokonza mapampu amafuta angaganizire izi, ndizosatheka kumvetsetsa. Kuphatikiza apo, chifukwa cha kuchuluka kwa kuvala kapena kulimba kwa pisitoni yamphamvu yamphamvu ndi makina amagetsi, kutentha ndi kukakamiza kwa silinda iliyonse mukakakamizidwa kudzakhalanso kosiyana. Ngakhale pampu ya jakisoni wamafuta yasokonekera pa benchi yoyeserera, mafuta a silinda iliyonse amakhala osagwirizana mukayika.
