Kuzindikira Kolakwa Kwa Cummins 300KVA Jenereta Yopangira Mafuta Opangira Mafuta

1.Fault matenda a kuthamanga wamba njanji mafuta dongosolo kotunga 300kva Cummins jenereta dizilo seti.

Masensa ndi ma actuators omwe amagwiritsidwa ntchito pamayendedwe othamanga kwambiri amafuta a njanji ali ndi mawonekedwe a kuchuluka, kulondola kwambiri komanso mayankho othamanga.Malingana ngati chinthu chimodzi chawonongeka, chidzakhudza kwambiri dongosolo lonse, ndipo ngakhale kuyambitsa kulephera kwa ntchito yabwino kapena kuyambitsa zipangizo.Mavuto omwe amakumana nawo pakuzindikira zolakwika za dongosololi ndiwonso ovuta kwambiri.

Chifukwa kamangidwe ndi kuwongolera kachitidwe kapamwamba kamene kamakhala ndi mafuta ochulukirapo a njanji ndizosiyana kwambiri ndi jenereta yachikhalidwe ya dizilo, zolakwika mu dongosololi ndizovuta kwambiri.Nthawi zambiri, zolakwikazo zitha kugawidwa m'magulu otsatirawa.

(1) Kulephera kwa dongosolo lamafuta obwera chifukwa cha kupsinjika pang'ono.

① Pali vuto ndi mpope wotumizira mafuta.Chochitika cholakwika ndi chakuti injini imayimilira itatha kutentha, liwiro lopanda ntchito silikhazikika ndipo kuthamanga kuli kofooka.Mutha kulumikiza chiwongola dzanja chamafuta pamndandanda pakati pa thanki yamafuta ndi gawo lamafuta a fyuluta yayikulu yamafuta, fufuzani kuchuluka kwamafuta (kuthamanga kwamafuta kuyenera kukhala kokulirapo kuposa 3bar pakuthamanga mwachangu), weruzani momwe pampu yotumizira mafuta ilili. , ndi kuthetsa vutolo pokonza kapena kusintha pampu yotumizira mafuta.

② Vuto la fyuluta yamafuta limasonyeza kuti zimakhala zovuta kuyamba kuzizira, zomwe zimayamba chifukwa cha madzi ochuluka mu fyuluta kapena kuwonongeka kwa chowotcha, makamaka m'nyengo yozizira.M'nyengo yozizira, madzi mu fyuluta ya 300kva Cummins jenereta iyenera kutulutsidwa nthawi zonse komanso momwe chotenthetsera chimagwirira ntchito.

(2) Kulephera kwa dongosolo lamagetsi lamafuta chifukwa cha kupsinjika kwakukulu.

Mbali yothamanga kwambiri yamagetsi operekera mafuta imagwiritsa ntchito kamera kuyendetsa mpope plunger ya pampu yothamanga kwambiri mmwamba ndi pansi kuti amalize kuyamwa kwa mafuta ndi kupopera.

① Pali vuto ndi pampu yothamanga kwambiri.Chochitika cholakwika ndi chakuti payipi yothamanga kwambiri imakhala ndi mphamvu yosakwanira yamafuta chifukwa cha kuwonongeka kwa zigawo za pampu yothamanga kwambiri.Cholakwika cha pampu yothamanga kwambiri chikhoza kuweruzidwa powerenga ndondomeko yowonongeka ya njanji yamagetsi yowonongeka ndi kusanthula deta.

② Pali vuto ndi sensa yodziwika bwino ya njanji.Chochitika cholakwika ndi chakuti injini imayimilira pambuyo poyambira, ndipo sichingayambitsidwenso pambuyo poyimitsidwa.Chifukwa chake ndi chakuti dzenje loyezera mafuta la sensa ya njanji wamba yatsekedwa kapena sensa yawonongeka, zomwe zimapangitsa kuti pakhale chizindikiro chachilendo cha sensa yodziwika bwino ya njanji yomwe imadziwika ndi ECU, kukakamiza injini kutseka.Gwiritsani ntchito ma multimeter kapena oscilloscope kuti muzindikire kutulutsa kwamagetsi kwa sensa (mtengo wamba ndi 0.5 ~ 4.5V), kuti muweruze cholakwika chotere.

③ Pali vuto ndi valavu yochepetsa kuthamanga kwa njanji.Chochitika cholakwika ndi chovuta kuyamba, kuthamanga kosakhazikika kosagwira ntchito komanso kuthamanga kofooka pakuyendetsa.Chifukwa chake ndi chakuti mphamvu yamafuta mu njanji wamba ndi yayikulu komanso yosakwanira chifukwa cha kutayikira kwa valve yoletsa kuthamanga kwa njanji.Ikhoza kuweruzidwa ndi kusanthula kayendedwe ka deta kachipangizo kakang'ono ka njanji ndi detector kapena oscilloscope pansi pa chikhalidwe cha kutera.

④ Pali vuto ndi chojambulira mafuta pamagetsi.Chochitika cholakwika ndi chakuti zimakhala zovuta kuyambitsa galimoto yotentha ndipo utsi wakuda umachokera ku chitoliro chotulutsa mpweya.Chifukwa chake ndi chakuti kusakaniza kumakhala kolemera kwambiri chifukwa cha jekeseni wosauka kapena kudontha kwa mafuta kwa jekeseni yamagetsi yamagetsi.Yang'anani ndi kusanthula mawonekedwe amakono a jekeseni wamafuta ndi oscilloscope kapena tester kuti mupitirize kuweruza cholakwika cha jekeseni wamafuta ndikuyikanso.

3. Kusamvetsetsa zolakwa ndi kukonza.

Pozindikira zolakwika ndikuweruza kwa njanji yamagetsi yamagetsi yamagetsi yamagetsi yoyendetsedwa ndi dizilo, ndi njira yachindunji yowerengera molunjika cholakwika ndi chowunikira pakompyuta kuti muwone cholakwikacho.Chifukwa chake, ambiri ogwira ntchito yosamalira amagwiritsa ntchito mwachindunji code yowerengera kuti aweruze malo olakwika, kapena kuyesa kuthetsa vutolo posintha magawo ndi magawo omwe akuwonetsedwa ndi cholakwikacho, Komabe, cholakwikacho sichingathetsedwe, chifukwa cholakwikacho sichimatero. zikutanthauza kuti zigawo zomwe zatchulidwa mu code yolakwika zilidi ndi vuto.Izi ndichifukwa choti zolakwika ndi malire omwe amakhazikitsidwa ndi ECU pagawo lililonse ndi osiyana, ndipo kuyanjana pakati pa zigawo zosiyanasiyana ndi zinthu zina zilipo.Zina mwa zolakwika zomwe zasungidwa ndi ECU zimatha kuwonetsa vuto lenileni, pomwe ena sangathe.Mwachitsanzo, zolakwa zina zimayambitsidwa ndi zolakwika zamakina, zomwe zimapangitsa kuti chizindikiro cha sensa chisokoneze kapena kupitirira malire, ndipo ECU idzafotokoza vuto la sensa.M'malo mwake, sensor si vuto.

Mwachidule, cholakwika sichikutanthauza kuti payenera kukhala cholakwika, ndipo palibe cholakwika sichikutanthauza kuti sipayenera kukhala cholakwika.Kuzindikira malo olakwika kudzera mu code yolakwika kungagwiritsidwe ntchito ngati chitsimikiziro.Zimafunikanso ogwira ntchito yosamalira kuti adziwe zinthu zazikulu zowunikira pambuyo pofufuza mosamala ndi kuweruza molingana ndi zomwe zachitika, chidziwitso ndi luso lamakono.Mothandizidwa ndi zida ndi mamita kuti azindikire magawo a magwiridwe antchito a zigawo, titha kuweruza zowona za code yolakwika, tipeze chifukwa chenicheni cha cholakwika ndikuzindikira malo olakwika.
