Iyo Fuel Pressure Regulator Inoshanda (Kutarisa uye Kutsiva iyo RTD)
Zviri mukati
Mune yekudzora sisitimu yeinjini yemotokari, imwe yemasvomhu modhi inoiswa pasi, uko ukoshi hwezvinobuda hunoverengerwa zvichienderana nekuyerwa kweiyo yekuisa. Semuenzaniso, nguva yekuvhurwa kwemanozzles zvinoenderana nehuwandu hwemhepo uye zvimwe zvakawanda zvakasiyana. Asi kunze kwavo, panewo zvinoramba zvichiripo, ndiko kuti, maitiro ehuni yehuni, yakanyoreswa muchiyeuchidzo uye kwete pasi pekutonga. Imwe yadzo ndeyekumanikidza kwemafuta munjanji, kana kuti, kusiyana kwayo pakati pezvipo uye zvinobuda zvemajekiseni.
Chii chinonzi fuel pressure regulator?
Mafuta kune majekiseni anobva mutangi nekuipomba nepombi yemagetsi yemafuta iri ipapo. Kugona kwaro kwakawandisa, ndiko kuti, kwakagadzirirwa kushandiswa kwakanyanya mune yakanyanya kuoma modhi, pamwe neakakosha muganho wekuderera kwekuita nekufamba kwenguva panguva yekushanda kwenguva refu.
Asi pombi haigone kugara ichipomba nesimba rose rekuchinja kwayo, kudzvanywa kunofanirwa kuve kwakaganhurirwa uye kudzikamiswa. Nokuda kweizvi, mafuta ekumanikidza regulators (RDTs) anoshandiswa.
Iwo anogona kuiswa ese ari maviri akananga mupombi module uye pane njanji yemafuta inodyisa majekiseni nozzles. Muchiitiko ichi, iwe unofanirwa kukanda iyo yakawandisa kuburikidza nemutsetse wekudonhedza (kudzoka) kudzokera mutangi.
Device
Iyo regulator inogona kuve yemagetsi kana yemagetsi. Muchiitiko chechipiri, iyi ndeye classic control system ine yekumanikidza sensor uye mhinduro. Asi yakapfava yemuchina haina kuvimbika zvishoma, nepo ichichipa.
Rail-mounted regulator inosanganisira:
- maviri cavities, imwe ine mafuta, imwe ine mhepo kuora mwoyo kubva kune yakawanda yekutora;
- elastic diaphragm inoparadzanisa maburi;
- spring-loaded control valve yakabatana kune diaphragm;
- imba ine kudzoka fittings uye vacuum hose kubva kune akawanda manifold.
Dzimwe nguva iyo RTD ine coarse mesh sefa yekupfuura peturu. Iyo yese regulator yakakwirirwa pane rampu uye inotaurirana nemukati wayo wemukati.
Ainoita
Kuti ugadzirise kudzvanywa pakati pemajekiseni ekupinda uye maburi, zvinodikanwa kuwedzera kune kukosha kwayo murampu vacuum isina kunaka mune yakawanda, uko injector nozzles inobuda. Uye sezvo kudzika kwevacuum kuchisiyana zvichienderana nekuremerwa uye dhigirii rekuvhura kweiyo throttle, iwe unofanirwa kutarisa mutsauko uchienderera, uchidzikamisa mutsauko.
Ipapo ndipo chete majekiseni achashanda neakajairwa maitiro ekuita kwavo, uye kuumbwa kwemusanganiswa hakuzodi kudzika uye kudzokororwa nguva nenguva.
Sezvo vacuum paRTD vacuum pombi inowedzera, vharuvhu inovhura zvishoma, ichirasa zvimwe zvikamu zvepeturu mumutsara wekudzoka, ichidzikamisa kutsamira kwemamiriro emuchadenga mune zvakawanda. Uku ndiko kumwe kugadzirisa.
Murau mukuru unokonzerwa nechitubu chinodzvanya vharuvhu. Zvinoenderana nekuoma kwayo, hunhu hukuru hweRTD hwakajairwa - iyo yakagadzikana kudzvanywa. Basa rinopfuurira maererano nemutemo wakafanana, kana pombi ichidzvinyirira nekudarika, ipapo hydraulic resistance yevhavha inoderera, mafuta akawanda anodonhedzwa zvakare mutangi.
Zviratidzo uye zviratidzo zveRTD isiri kushanda
Zvichienderana nemhando yekusashanda, kumanikidza kunogona kuwedzera kana kuderera. Saizvozvo, musanganiswa unopinda mumasilinda unopfumiswa kana kupera.
Iyo control unit iri kuyedza kugadzirisa kuumbwa, asi kugona kwayo kushoma. Kupisa kunokanganiswa, mota inotanga kushanda nguva nenguva, kupenya kunonyangarika, kubata kunoderera, uye kushandiswa kunowedzera. Uye mune chero mamiriro ezvinhu, musanganiswa wacho unopera, kana kupfumiswa. Panguva imwecheteyo, inopisa zvakaenzana zvakashata.
Maitiro ekutarisa mudziyo kuti unoshanda sei
Kuti utarise, kumanikidzwa mune rampu kunoyerwa. Yakagadzirirwa nevhavha iyo iyo test pressure gauge inogona kubatanidzwa. Chigadzirwa chacho chicharatidza kana kukosha kuri mukati memaitiro kana kwete. Uye kukanganisa kwakananga kwemutongi kucharatidzwa nechimiro chekuita kwekuverenga kusvika pakuvhurwa kwe throttle uye kudzima mutsara wekudzoka, izvo zvakakwana kupinza kana kuvhara hose yayo inoshanduka.
Kubvisa iyo vacuum hose kubva kuRTD yekukodzera kucharatidzawo yakakwana yekumanikidza mhinduro. Kana injini yaimhanya zvishoma nezvishoma, kureva kuti, vacuum yakanga yakakwirira, saka kuparara kwevacuum kunofanira kukonzera kuwedzera kwekumanikidzwa muchitima. Kana zvisina kudaro, regulator haisi kushanda nemazvo.
Nzira yekuchenesa RTD
Iyo regulator haigone kugadziriswa, kana paine kusashanda iyo inotsiviwa neimwe nyowani, mutengo wechikamu wakaderera. Asi dzimwe nguva zvinokwanisika kudzoreredza simba rekushanda nekuchenesa yakavakirwa-mukati sefa mesh. Kuti uite izvi, mutongi anobviswa uye akashambidzwa ne carburetor cleaner, inoteverwa nekuchenesa.
Kuvhiya kunogona kudzokororwa kune mhedzisiro iri nani. Izvo zvinokwanisika kushandisa ultrasonic solvent bath, iyo inoshandiswa kuchenesa majekiseni apo matambudziko akafanana anomuka nekuda kwemafuta ane tsvina.
Iko hakuna imwe pfungwa mumaitiro aya, kunyanya kana chikamu chakatoshanda zvakanyanya. Mutengo wenguva nemari wakaenzana nemutengo weRTD itsva, zvisinei nekuti vharafu yekare yakasakara, diaphragm yakwegura, uye caustic yekuchenesa makomisheni inogona kukonzera kutadza kwekupedzisira.
Mirayiridzo yekutsiva mafuta ekumanikidza regulator uchishandisa muenzaniso weAudi A6 C5
Kuwanikwa kune regulator pamakina aya kuri nyore, inoiswa panjanji yemafuta ejekiseni.
- Bvisa chivharo chepurasitiki chekushongedza kubva pamusoro pemotokari nekusunungura mabheji ekumonyorora counterclockwise.
- A screwdriver inoshandiswa kupuruzira uye kubvisa iyo inogadzirisa chitubu clip pane regulator muviri.
- Bvisa hose yevacuum kubva kune regulator fitting.
- Residual pressure munjanji inogona kurerukirwa nenzira dzakasiyana nekurega injini ichimhanya nepombi yemafuta ichidzimwa, kudzvanya pane spool yevharuvhu yegeji renjanji, kana kungobvisa hafu yeimba inodzora. Muzviitiko zviviri zvekupedzisira, unofanirwa kushandisa rag kutora peturu inobuda.
- Ne latch yakabviswa, mutongi anongobviswa kubva munyaya yacho, mushure mokunge inogona kushambidzwa, inotsiviwa neimwe itsva, uye yakaungana munhevedzano yakarongeka.
Usati waiswa, zvinokurudzirwa kuisa chisimbiso zvindori zverubha kuitira kuti urege kuvakuvadza kana wakanyura mumudziyo.
