Kusamala Kusamalira High Pressure Common Rail Dizilo jenereta

Wopanga majenereta a dizilo a Cummins amakuphunzitsani chidziwitso chokonzekera: kusamala pakukonza jenereta wamba wa njanji ya dizilo.

1. Kugwiritsa ntchito tsiku ndi tsiku

Jenereta wa dizilo wamba wothamanga kwambiri amakhala ndi preheater.Ikayambika pansi pa kutentha kochepa, chosinthira cha preheating chimatha kuyatsidwa poyamba.Kuwala kwa preheater kukayaka, zikuwonetsa kuti preheater iyamba kugwira ntchito.Pambuyo pa kutentha kwanthawi yayitali, jenereta ya dizilo imatha kuyambika pambuyo poti chizindikiro cha preheating chazimitsidwa.Chizindikiro cha preheating chimakhalanso ndi ntchito ya alamu.Ngati preheating chizindikiro kumawalira pa ntchito wamba njanji dizilo jenereta, izo zikusonyeza kuti jenereta ya dizilo dongosolo lolamulira lalephera ndipo liyenera kukonzedwa posachedwa.

Osagwiritsa ntchito madzi othamanga kwambiri kuti azitsuka jekeseni wamafuta a jenereta wamba wa njanji ya dizilo, chifukwa madzi akalowa mugawo lamagetsi, sensa, actuator ndi cholumikizira chake, cholumikizira nthawi zambiri chimakhala dzimbiri, zomwe zimabweretsa "zofewa" zovuta kupeza mu dongosolo lamagetsi lamagetsi.

The electronic control unit, sensa ndi actuator ya high-voltage common njanji dizilo jenereta makamaka tcheru voteji.Ngakhale batire ili ndi mphamvu pang'ono kutaya mphamvu, izo zidzakhudza ntchito yachibadwa ya dongosolo lamagetsi lamagetsi.Choncho, m'pofunika kusunga mphamvu yosungirako batire mokwanira.Ngati kuwotcherera kukonza ikuchitika pa mkulu-voteji wamba njanji dizilo jenereta, chingwe cha batire ayenera disassembled, cholumikizira cha ECU ayenera kusagwirizana, ndipo ndi bwino kuchotsa mwatsatanetsatane unit mphamvu zamagetsi.Magawo amagetsi amagetsi, masensa, ma relay, ndi zina zambiri ndi zigawo zotsika kwambiri, ndipo kuwonjezereka komwe kumapangidwa panthawi yowotcherera ndikosavuta kwambiri kuwotcha zida zamagetsi zomwe zili pamwambapa.

Kuphatikiza apo, opareshoni yotsatira imatha kuchitika pambuyo poti jenereta ya dizilo yothamanga kwambiri ya njanji yatsekedwa kwa osachepera 5min, kuti mupewe kuvulala kwamunthu chifukwa cha jekeseni wothamanga kwambiri wamafuta.

2. Njira zoyeretsera

Mkulu kuthamanga wamba njanji dizilo jenereta ali okhwima amafuna mankhwala mafuta, ndi zili sulfure, phosphorous ndi zosafunika ndi otsika kwambiri.Mafuta a dizilo owala kwambiri komanso mafuta a injini ayenera kugwiritsidwa ntchito.Mafuta a dizilo osakhala bwino ndi osavuta kuyambitsa kutsekeka komanso kuvala kwachilendo kwa majekeseni amafuta.Choncho, m'pofunika nthawi zonse kukhetsa madzi ndi zinyalala mu olekanitsa mafuta-madzi, ndi kuyeretsa nthawi zonse kapena m'malo fyuluta dizilo ndi mafuta fyuluta.Poona kuti khalidwe la dizilo ntchito wa seti zoweta jenereta n'zovuta kukwaniritsa zofunika mkulu-anzanu wamba njanji dizilo jenereta, tikulimbikitsidwa kugwiritsa ntchito zina zapadera dizilo kuwonjezera pa thanki mafuta ndi kuyeretsa mafuta. dongosolo pafupipafupi.

Musanaphatikize dongosolo la jakisoni wamafuta, kapena pomwe mphuno ya zida zama jakisoni wamafuta (monga jekeseni wamafuta, chitoliro choperekera mafuta, ndi zina zotero) ipezeka kuti yadetsedwa ndi fumbi, tikulimbikitsidwa kugwiritsa ntchito zida zoyamwa fumbi kuti mutenge fumbi lozungulira. , ndipo musagwiritse ntchito kupopera kwa gasi wothamanga kwambiri, kuwomba madzi othamanga kwambiri kapena kuyeretsa pogwiritsa ntchito makina opangira magetsi.

Chipinda chosungirako jenereta ndi zida ziyenera kukhala zaukhondo kwambiri kuti zisawonongeke fumbi.M'chipinda chosungirako jenereta, tinthu tating'onoting'ono ndi ulusi wowononga jekeseni wamafuta saloledwa, ndipo makina owotcherera, makina opera ndi zida zina zomwe zingawononge dongosolo la jekeseni wamafuta siziloledwa.

Zovala za ogwira ntchito yokonza ziyenera kukhala zaukhondo, ndipo siziloledwa kunyamula fumbi ndi zitsulo zachitsulo.Sizololedwa kuvala zovala zofiyira popewa kuipitsa jekeseni wamafuta.Sambani m'manja musanayambe ntchito yokonza.Kusuta ndi kudya ndizoletsedwa mwamtheradi panthawi ya opaleshoni.

3. Disassembly, kusungirako ndi kunyamula mbali.

Pambuyo mkulu-anzanu wamba njanji seti yopanga dizilo imathamanga, ndizoletsedwa kugawanitsa dongosolo la jakisoni wa njanji yapamwamba kwambiri.Mukachotsa kapena kuyika chitoliro chobwezera mafuta cha pampu yamafuta othamanga kwambiri, kakamizani mbali ya axial kuti musapindike.Mtedza uliwonse uyenera kumangirizidwa ku torque yomwe yatchulidwa ndipo sudzawonongeka.Makina operekera mafuta akatha kutha, ngakhale nthawiyo ili yochepa kwambiri, kapu yoteteza yoyera iyenera kuvala nthawi yomweyo, ndipo chipewa choteteza chimatha kuchotsedwa musanayambe kukonzanso.Zida za jekeseni wa njanji yothamanga kwambiri ziyenera kutsegulidwa musanagwiritse ntchito, ndipo chipewa choteteza chiyenera kuchotsedwa musanasonkhene.

Mukamasunga ndi kunyamula zida za jenereta za dizilo zothamanga kwambiri, jekeseni wamafuta, msonkhano wapampopi wamafuta othamanga kwambiri, msonkhano wa njanji yamafuta ndi zida zina za jekeseni ziyenera kuvala zipewa zoteteza, ndipo jekeseni wamafuta azikutidwa ndi pepala lamafuta.Zigawozo ziyenera kupewedwa kuti zisagundane panthawi yoyendetsa.Powatenga ndi kuwayika, amatha kukhudza thupi la ziwalozo.Ndikoletsedwa kukhudza zolumikizana za mapaipi olowera ndi potuluka mafuta ndi mabowo a nozzle a jekeseni wamafuta, kuti tipewe kuipitsa njira yojambulira njanji yothamanga kwambiri.
