Disassembly Sequence ndi Kukonza Njira ya Fuel Injector of Diesel Engine

Injector yamafuta ndi gawo lofunikira kwambiri pamayendedwe amafuta a injini ya dizilo.Ntchito yake ndikupopera mafuta a dizilo othamanga kwambiri kuchokera ku mpope wa jekeseni wamafuta kupita kuchipinda choyaka ngati nkhungu, ndikupanga chisakanizo choyaka bwino ndi mpweya woponderezedwa muchipinda choyaka.Injector yamafuta sikuti imangotsimikizira mtundu wa kutsitsi kwa dizilo, mgwirizano pakati pa mtengo wamafuta ndi chipinda choyaka moto, komanso imakhudzanso mayendedwe a jekeseni wamafuta, nthawi ya jekeseni wamafuta ndi kukhazikika kwa jekeseni wamafuta, zomwe zimakhudzanso magwiridwe antchito amafuta. injini.Choncho, zofunikira pa ntchito ya jekeseni ndi: kuthamanga kwina kwa jekeseni ndi kusiyanasiyana, komanso ngodya yoyenera yopopera, ndikugwirizanitsa ndi mawonekedwe a chipinda choyaka moto.Kuphatikiza apo, jekeseni wamafuta amatha kuyimitsidwa mwachangu kumapeto kwa jekeseni wamafuta popanda kudontha mafuta.

imodzi: kukonza jekeseni wamafuta

Pambuyo poyeretsa mbali za jekeseni, ngati pali zina mwazinthu zosazolowereka zomwe zapezeka, ziyenera kukonzedwa kapena kusinthidwa.Pamene kumapeto kwa jekeseni thupi la jekeseni pamodzi ndi thupi la singano valavu ili ndi kuwonongeka pang'ono, chotsani zikhomo ziwirizo ndikugaya mbale Pogaya.Samalani kuti musakhudze mbali yokhotakhota potulutsa pini yoyikapo.
② Pamene pamwamba pa kasupe woyendetsa kasupe wa jekeseni wamafuta akakanda, atsekeredwa kapena kupunduka kosatha, ayenera kusinthidwa.
③ Magawo a kaboni mkati mwa phewa lamkati ndi khoma la dzenje la kapu yolimba ya jekeseni ayenera kuchotsedwa kwathunthu.
④ Chigawo cham'mimba mwake cha jekeseni wa jekeseni wa mafuta chimavalidwa, ndipo chiyenera kusinthidwa ngati pali kutaya kwakukulu.
⑤ Pamene mabowo amphuno ali ndi zolakwika monga kuvala ndi kukulitsa, zomwe zimakhudza ubwino wa kupopera ziyenera kusinthidwa.
⑥ Ngati mpando wosindikizira pamwamba pa valavu ya singano ndi thupi la singano sunathe kwambiri, ukhoza kukonzedwa ndi kugayana ndi phala la aluminiyamu.Pogaya wina ndi mzake, musagwiritse ntchito mphamvu zambiri, ndipo malo osindikizira amatha kufika pa yunifolomu osati yosindikizira kwambiri.
⑦ Chifukwa cha kubwezeredwa kwa gasi mu silinda ya injini ya dizilo kapena kulowerera kwa zonyansa zabwino mu jekeseni wamafuta, valavu ya singano imakhala yakuda kapena kumamatira.Pambuyo poyeretsa ndi kufufuzana, ikhoza kugwiritsidwanso ntchito kapena kusinthidwa malinga ndi kuopsa kwa vutoli.

ziwiri: Zinthu zofunika kuziganizira pakuphatikiza jekeseni

① Pa nthawi yonse yojambulira jekeseni wamafuta, zigawozo ziyenera kukhala zoyera, makamaka zisindikizo za jekeseni wamafuta omwewo komanso nkhope yomaliza ya jekeseni.Ngakhale zinyalala zing'onozing'ono ndi fumbi zimatha kuyambitsa kutsekeka kotsetsereka ndipo Kusindikiza kwa malo olumikizana ndikosauka.The scapular pamwamba pomwe kapu yolimba ya jekeseni wamafuta imalumikizana ndi jekeseni wamafuta iyenera kukhala yosalala komanso yosalala, ndipo palibe ma depositi a kaboni kapena ma burrs amaloledwa, apo ayi zingakhudze coaxiality ndi verticality ya kuyika kwa msonkhano wa jekeseni wamafuta, potero kumayambitsa kutsetsereka kwa jekeseni wamafuta koyipa.
② Mukasonkhanitsa, choyamba pindani mu chitoliro cholowetsa mafuta chomwe chili ndi phata la zosefera, ndikusindikiza mwamphamvu gasket yamkuwa kuti mutseke cholimba popanda kutulutsa mafuta.Kenaka ikani mphamvu yoyendetsera kasupe ndi ndodo ya ejector mu thupi la jekeseni, piritsani muzitsulo zoyendetsera mphamvu mpaka ingokhudza kuthamanga kwa kasupe, ndiyeno pukutani pazitsulo zoyendetsera mtedza.
③ Gwirani jekeseni wamafuta mozondoka pa benchi vise, ikani jekeseni wa mafuta, ndikumangitsani kapu.Kulimbitsa makokedwe ndi 59-78 Nm (6-8kgf.m).Kuchulukirachulukira kumapangitsa kusintha kwa ma valve a singano, kusokoneza magwiridwe antchito a valavu ya singano, ndipo torque yaying'ono imapangitsa kuti mafuta azituluka.
④ Gulu la jekeseni wamafuta lomwe lasonkhanitsidwa liyenera kuyesedwa pa benchi yoyesera kuti lisindikize ndi kupopera mbewu mankhwalawa, ndipo kuthamanga kwa jekeseni wamafuta kuyenera kusinthidwa.
