Momwe Fuel Pressure Regulator Imagwirira Ntchito (Kuwona ndi Kusintha RTD)
Zamkatimu
Mu dongosolo lowongolera la injini yamagalimoto, mtundu wina wa masamu umayikidwa, pomwe zotuluka zimawerengedwa kutengera muyeso wa zomwe zalowetsedwa. Mwachitsanzo, nthawi yotsegulira ma nozzles imadalira kuchuluka kwa mpweya ndi zina zambiri. Koma pambali pawo palinso zokhazikika, ndiko kuti, mawonekedwe a dongosolo lamafuta, olembetsedwa pamtima komanso osayang'aniridwa. Chimodzi mwa izo ndi kuthamanga kwa mafuta mu njanji, kapena kani, kusiyana kwake pakati pa zolowetsa ndi zotulutsa za jekeseni.
Kodi owongolera zamagetsi ndi chiyani?
Mafuta opangira ma jekeseni amachokera ku thanki poyipopera ndi pampu yamagetsi yamagetsi yomwe ili pamenepo. Kuthekera kwake ndikocheperako, ndiko kuti, amapangidwira kuti azigwiritsa ntchito kwambiri munthawi yovuta kwambiri, kuphatikiza malire ake pakuwonongeka kwa magwiridwe antchito pakapita nthawi pakapita nthawi yayitali.
Koma mpope sungathe kupopera nthawi zonse ndi mphamvu zonse za kusintha kwake, kupanikizika kuyenera kukhala kochepa komanso kokhazikika. Pazifukwa izi, mafuta owongolera mafuta (RDTs) amagwiritsidwa ntchito.
Zitha kukhazikitsidwa mwachindunji mu module ya pampu komanso panjanji yamafuta yomwe imadyetsa ma nozzles a jekeseni. Pamenepa, muyenera kutaya zochulukirapo kudzera mumzere wopopera (kubwerera) kubwerera mu thanki.
chipangizo
Wowongolera amatha kukhala wamakina kapena zamagetsi. Pachiwonetsero chachiwiri, iyi ndi njira yachikale yowongolera yokhala ndi sensor yokakamiza komanso mayankho. Koma makina osavuta sakhala odalirika, pomwe ndi otchipa.
Regulator yokwera njanji imakhala ndi:
- mikwingwirima iwiri, imodzi imakhala ndi mafuta, ina imakhala ndi kupsinjika kwa mpweya kuchokera kumagulu osiyanasiyana;
- zotanuka diaphragm kulekanitsa mapanga;
- valavu yoyendetsa kasupe yolumikizidwa ndi diaphragm;
- nyumba yokhala ndi zolumikizira zobwerera ndi paipi yotsekera kuchokera pazolowera zambiri.
Nthawi zina RTD imakhala ndi fyuluta ya mesh yomata podutsa mafuta. Chowongolera chonsecho chimayikidwa panjira ndikulumikizana ndi mkati mwake.
Momwe ntchito
Pofuna kukonza kupanikizika pakati pa ma injectors ndi malo ogulitsa, m'pofunika kuwonjezera pa mtengo wake mumsewu mpweya woipa muzobweza zambiri, kumene ma jekeseni amatuluka. Ndipo popeza kuya kwa vacuum kumasiyanasiyana malinga ndi katundu ndi kuchuluka kwa kutsegula kwa phokoso, muyenera kuyang'anitsitsa kusiyana kwake mosalekeza, kukhazikika kusiyana.
Pokhapokha pamene majekeseni adzagwira ntchito ndi miyezo yoyenera ya ntchito yawo, ndipo mapangidwe a osakaniza sadzafuna kuwongolera mozama komanso pafupipafupi.
Pamene vacuum pa RTD vacuum chitoliro chikuwonjezeka, valavu idzatsegula pang'ono, kutaya magawo ena a mafuta mumzere wobwerera, ndikukhazikitsa kudalira kwa mlengalenga muzinthu zambiri. Uku ndikuwongolera kowonjezera.
Lamulo lalikulu ndi chifukwa cha kasupe kukanikiza valavu. Malinga ndi kuuma kwake, khalidwe lalikulu la RTD ndilokhazikika - kuthamanga kokhazikika. Ntchitoyi imapitirira molingana ndi mfundo yomweyi, ngati pampu ikukwera mopitirira muyeso, ndiye kuti kukana kwa hydraulic kwa valve kumachepa, mafuta ochulukirapo amabwereranso mu thanki.
Zizindikiro ndi zizindikiro za RTD yosagwira ntchito
Kutengera ndi momwe zimagwirira ntchito, kupanikizika kumatha kuwonjezereka kapena kuchepa. Chifukwa chake, kusakaniza komwe kumalowa m'masilinda kumalemeretsa kapena kutha.
Chigawo chowongolera chikuyesera kukonza zomwe zidapangidwa, koma mphamvu zake ndizochepa. Kuwotcha kumasokonekera, injini imayamba kugwira ntchito pang'onopang'ono, kung'anima kutha, kukoka kumawonongeka, ndipo kugwiritsa ntchito kumawonjezeka. Ndipo mulimonse momwe zingakhalire, kusakaniza kwatha, kapena kupindula. Pa nthawi yomweyo, amayaka mofanana kwambiri.
Momwe mungayang'anire chipangizocho kuti chizigwira ntchito
Kuti muwone, kuthamanga kwa rampu kumayesedwa. Ili ndi valavu yomwe gitala yoyesera imatha kulumikizidwa. Chipangizocho chidzawonetsa ngati mtengo uli mkati mwachizolowezi kapena ayi. Ndipo cholakwika chenicheni cha wowongolera chidzawonetsedwa ndi momwe mawerengedwe amachitikira pakutsegulira kwa throttle ndikuzimitsa mzere wobwerera, womwe ndi wokwanira kutsina kapena kulumikiza payipi yake yosinthika.
Kuchotsa payipi ya vacuum pa RTD yokwanira kudzawonetsanso kuyankha kokwanira. Ngati injini ikuyenda pa liwiro locheperako, ndiye kuti, vacuum inali yayikulu, ndiye kuti kutha kwa vacuum kuyenera kuyambitsa kupanikizika kwa njanji. Ngati sichoncho, chowongolera sichikuyenda bwino.
Momwe mungayeretsere RTD
Woyang'anira sangathe kukonzedwa, ngati atasokonezeka amasinthidwa ndi watsopano, mtengo wa gawolo ndi wotsika. Koma nthawi zina ndizotheka kubwezeretsanso mphamvu zogwirira ntchito poyeretsa mauna omangidwa mkati. Kuti muchite izi, chowongoleracho chimachotsedwa ndikutsukidwa ndi chotsuka cha carburetor, kenako ndikuyeretsa.
Ntchitoyi ikhoza kubwerezedwanso kuti mupeze zotsatira zabwino. N'zothekanso kugwiritsa ntchito kusamba kwa ultrasonic zosungunulira, zomwe zimagwiritsidwa ntchito kuyeretsa majekeseni pamene mavuto ofanana amayamba chifukwa cha mafuta onyansa.
Palibe mfundo yeniyeni muzochitika izi, makamaka ngati gawolo latumikira kale kwambiri. Mtengo wa nthawi ndi ndalama ndizofanana ndi mtengo wa RTD yatsopano, ngakhale kuti valavu yakale yatha kale, diaphragm yakalamba, ndipo mankhwala oyeretsa a caustic angayambitse kulephera komaliza.
Malangizo m'malo mafuta kuthamanga regulator ntchito chitsanzo Audi A6 C5
Kufikira kwa owongolera pamakinawa ndikosavuta, kumayikidwa panjanji yamafuta a injectors.
- Chotsani chivundikiro cha pulasitiki chokongoletsera pamwamba pa galimotoyo pomasula zingwe zopindika mozungulira.
- Chophimbacho chimagwiritsidwa ntchito pochotsa ndikuchotsa kasupe wokhazikika panyumba yowongolera.
- Chotsani payipi ya vacuum kuchokera pa chowongolera.
- Kuthamanga kotsalira mu njanji kungathetsedwe m'njira zosiyanasiyana mwa kulola injini kuthamanga ndi pampu yamafuta yazimitsidwa, kukanikiza pa spool ya valve gauge pa njanji, kapena kungodula theka la nyumba zowongolera. Muzochitika ziwiri zomaliza, muyenera kugwiritsa ntchito chiguduli kuti mutenge mafuta omwe akutuluka.
- Latch ikachotsedwa, wowongolera amangochotsedwa pamlanduwo, pambuyo pake amatha kutsukidwa, kusinthidwa ndi chatsopano, ndikusonkhanitsidwa motsatira dongosolo.
Musanakhazikitse, tikulimbikitsidwa kuti muzipaka mphete za mphira zosindikizira kuti zisawonongeke mukamizidwa muzitsulo.
