HPFP mumayuniti edhiziri. Nheyo yekushanda kwe-in-line pombi mumainjini

24.11.2022 /

Kare, mafuta edhiziri aipihwa mukamuri yekupisa nema compressor pamwe nemhepo. Iko kushanduka kwemainjini edhiziri kwakawedzera nekuvandudzwa kwetekinoroji, zvichikonzera kuunzwa kwepombi yejekiseni. Chii chinokonzeresa chinhu ichi uye ndedzipi mhando dzayo? Dzidza nezve anowanzo kutadza pombi uye tsvaga izvo zvinofanirwa kuitwa kuti zvirambe zvichimhanya kwenguva yakareba sezvinobvira!

TNVD - chii ichocho?

Mune mamwe mazwi, ichi chishandiso chejekiseni kana chingori chishandiso chakagadzirirwa kupa mafuta kune majekiseni pasi pekumanikidzwa kwakanyanya. Ichi chikamu chiri pedyo zvikuru nemasilinda uye inotungamirirwa nebhanhire renguva. Pasi pechiito chekutenderera kwekufamba, simba rinogadzirwa pagumbo regiya, iro rinogadzira kudzvanywa. Kwemakore, marudzi akati wandei emapombi akagadzirwa anoshanda mumotokari dzedhiziri dzakakura kusvika nhasi. Heino rondedzero yavo pfupi.

Mhando dzemapombi ehutsi hwepamusoro mumajini edhiziri

Parizvino, mapombi anotevera akaonekwa mumainjini akaiswa pamotokari:

  • line;
  • kutenderera.

Chinangwa chebasa ravo chakafanana, asi magadzirirwo acho akasiyana zvakanyanya kubva kune mumwe nemumwe. Ngatitarisei kune chaiyo yebasa ravo.

In-line jekiseni pombi - dhizaini uye kushanda kwemapombi echikamu

Chigadzirwa chacho chakatanga muna 1910. Iyo in-line pombi ine zvikamu zvekupomba zvakapatsanurwa, chimwe nechimwe chinoronga huwandu hwemafuta anopihwa kune imwe silinda. Iko kudzoreredza kufamba kwepiston musangano kunopa kudzvanywa kwakakodzera. Iyo giya rack inoita kuti piston itenderere uye inogadzirisa dosi remafuta. Kwemakore anopomba ne:

  • yakagadziriswa kutanga uye kugadziriswa kupera kwejekiseni;
  • kushanduka kwekutanga uye kwakagadziriswa kuguma kwejekiseni;
  • inogadziriswa kutanga uye inogadziriswa kupera kwejekiseni.

Muchina wejekiseni wechikamu wakabviswa nekuda kwematambudziko akati wandei. Paive nedambudziko nekunyatso kurongeka kwedosi yemafuta, kushandiswa kwakanyanya kwemafuta edhiziri muinjini uye mitengo yakakwira yekugadzira.

Distributor injection pump - musimboti wekushanda

Majekiseni pombi akashandiswa muinjini dzedhiziri kwenguva yakareba mushure mekunge VAG TDI injini dzapinda mumusika. Dzakashandiswa kare, asi dzaive muzvikamu izvi zvakava nemukurumbira. Kushanda kwepombi yakadaro kunobva pane piston-distribution unit iri mukati maro. Dhizaini yayo yakavakirwa pane yakakosha ledge disc (colloquially inozivikanwa se "wave") painofambiswa piston yekuparadzira. Nekuda kwekutenderera uye kufamba kwechinhu, dosi yemafuta inopihwa kune yakatarwa mafuta mutsara. Pombi yekugovera ine chikamu chimwe chepombi.

HPFP uye majekiseni eyuniti - kuenzanisa

Mapundu epressure iboka rakakosha remajekiseni nekuti anobvisa echinyakare pombi. Izvo zvinosanganisira muromo uye mudziyo wekupomba, izvo zvinogadzira yakanyanya kukwira mafuta. Zvose zviri zviviri zvakabatanidzwa pamwe chete uye simba rinodiwa kushanda chikamu chepombi rinobva kune camshaft lobes. Kune rumwe rutivi, iyi mhinduro inopa mafuta kupikisa kwakakosha uye inobvumira kuti igadzire kudzvinyirira kwakanyanya. Nekune rimwe divi, elastomers anoshandiswa kuisa chisimbiso anowanzo kuoma nekuda kwekupisa kwakanyanya uye kukonzera kusashanda zvakanaka kweyuniti jekiseni.

Injection pump leakage - zviratidzo zvekukuvadza

Nzira yakareruka yekuona kuti pombi irikudonha ndeye apo mafuta anoyerera achibuda mumba mayo. Zvisinei, rudzi urwu rwekukuvara haruoneki nguva dzose. Zvinonyanya kuoma kuona kana paine nzvimbo pakati pemudziyo uyu nejini block. Naizvozvo, chiratidzo chinotevera chinogona kunge chiri mhepo mujekiseni system. Izvi zvichanzwika nenzira yejerks yemagetsi unit (kunyanya panguva yakaoma kukurumidza).

Kukanganisa jekiseni pombi - zviratidzo uye zvikonzero

Mukuwedzera kune zviitiko zvataurwa, high-pressure fuel pumps inotambura nezvimwe zvirwere. Kutora chikamu chepombi kunogona kuva dambudziko guru. Chikonzero chedambudziko ndechekuwedzera mafuta nemafuta asina kunaka. Iyo yekudyisa inozorwa chete nemafuta edhiziri, uye kuvepo kwetsvina yakasimba muvharuvhu kunokonzera kukwenya kwepamusoro pepiston distributor. Kazhinji pane kukuvadzwa kwemusoro, iyo yakagadzirirwa kupa mafuta kune chaiwo majekiseni. Zvadaro kugadzirisa uye kuvandudzwa kwepombi yejojo ​​inodiwa.

Nzira yekuziva sei kusashanda kwepombi yejekiseni uye kuigadzirisa?

Chii chichaitika kune drive? Nekuda kwekupfeka kana kukuvadzwa kwepombi, mota:

  • zvinetso zvemoto;
  • inoburitsa utsi hwakawanda;
  • inopisa mafuta akawanda;
  • matanda asina basa kana adziyirwa. 

Zvadaro zvakakosha kudzorerazve mudziyo wose uye kutsiva munhu mumwe nomumwe zvinhu. Iyo rotary jekiseni pombi haisi iyo yazvino tekinoroji mhinduro, saka dzimwe nguva zvinogona kunetsa kuwana zvikamu zvakafanira.

Usakanganwa kutarisira pombi yejojo, nokuti nenzira iyi iwe uchadzivisa matambudziko anotsanangurwa. Nzira dzekushanda-dzisina matambudziko dziri nyore uye dzinogumira pakudira mafuta emhando. Zvakare, usaregeredza kuisirwa nguva dzose kwemafuta sefa. Tsvina kubva mutangi inogona kukuvadza nzvimbo dzekukweshana uye kukonzeresa kutadza kwepombi pachayo kana nozzles. Kana iwe ukachengeta mitemo iyi mupfungwa, pombi yako ichagara kwenguva refu.
