Hangaiwa plunger jekiseni pombi: operative zvinodiwa, mhando zvikanganiso uye uchishandisa pfungwa

Munguva ichangopfuura, vanhu vakawanda vakatanga kushandisa Diesel motokari. Uye nokuda kwechikonzero chakanaka. Saka, ichi ndicho yakakwirira compression reshiyo, pasi mafuta rakawanda, traction zvakanaka yakaderera revs. Chimwe chikuru zvinoumba chinotsva ezvinhu ari Diesel injini - a pombi. maumbirwo awo rinosanganisira peya plunger pombi. Chii chinhu ichi uye nei zvichidikanwa? Tinotaura izvi munyaya yedu nhasi.

mamiriro

Hwaro mukuru-kufurirwa mafuta pombi chinokosha pombi chikamu. It unotora munhu plunger (pisitoni) uye humburumbira ane diki ruoko chimiro. peya ichi yenhengo akagadzirwa mukuru-simba steels, nokuti anoshanda pasi kumusoro kumanikidzwa. Plunger mhute pombi anoita basa rakasikwa huni nevezera inodiwa spraying nayo mberi kupinda combustion yomukati. Ona kuti mashandiro uyu zvakarurama. The chikuru hunhu ine peya plunger pombi (Zexel kusanganisira), - chaiwo chipimo chemushonga peturu nomurau kwayo kumanikidzwa.

mudziyo

raiva pedyo nebundu ichi vanosanganisira grooves maviri:

• Zononoka.
• Longitudinal.

Pacharo rinosanganisira peya pamusoro ruoko 4 plungers 5. gwara yokutanga 2 vari - uye yokunzvenga Inlet. Ose interconnected pamwe combustion yomukati. Pamusoro plunger vaviri zvakakodzera ane hwakawanda cone.

Nokuda mukuru nemazvo machine womukati humburumbira plunger mhute pombi anogona kushanda panguva nematambudziko anosvika 200 MPa. Hunhu pombi kwakadaro dzimwe nguva kupfuura vaya kwakajairika pisitoni pombi. The chipimo chemushonga of huni iri nokuda plunger unotii. Saka, kuwanda musanganiswa dzingasiyana yepamusoro kana kudzika zvichienderana kwadzinoita mudzimu injini. vanoungana date zvinhu zvinodiwa yakakwirira zvakakwana - inowanikwa pakati yomukati dzokunze pose humburumbira haafaniri kupfuudza 3 microns.

Plunger mhute pombi ane yokudadira mumuviri. Iye anodzinga munhu zvekutepfenyura giya. Kuburikidza ruoko ichi pachayo dzinodzorwa (humburumbira). Rail kunoita injini nokukurumidza regulator. Saka zviri kubudirira chipimo chemushonga dzichifura kutenderera pasina kuchinja nokuvatema plunger.

musimboti oparesheni

The algorithm kunobva mashandiro chiito pamusoro reciprocating kufamba mikuru zvikamu zviviri. pisitoni ichi uye ruoko pamusoro cylindrical chimiro. Panguva reciprocating kufamba huni iri vakanwa kupinda pombi. The jekiseni anotora nzvimbo kuburikidza mumakomba ari ruoko. Cherechedza kuti huru basa mumwe mashandiro akadai plunger, iri chipimo chemushonga peturu uye unokupai kuna sepombi. Kuwedzera kune chaiyo peturu anofanira kupinda humburumbira chete pane imwe nguva. Kushanda mashandiro yakaitwa pasina dzongonyedzo, kuti hangaiwa uku zvigadziriswe vane yakakwirira rwokugadzira zvinodiwa. Saka, kana chinotsva pombi bindepinde pane mukuru vachimanikidzwa mugero pakati plunger uye mafuta mutsetse. Izvi inowana zvinoderedza huni nevezera kuti zvinokosha kuti kutsanya uye zvinonyatsochengeta wokugumisa jekiseni mokugezera. Kwakadaro basa zvigadziriswe chinonditadzisa huni mumate. Kana ane Shamhu jekiseni, zvinoyerera vharuvhu cône rinobuda. Uyezve, mafuta pasi kumusoro kumanikidzwa zvokudya kusvikira pfapfaidzo pfuti, akagura vharuvhu uye mafuta anaro. Apo akazarura zvaimutambisira mugero kumanikidza ipfupi muimba yomukati. Tsime pazvisviniro kuerera vharafu plunger pokugara pachigaro. Izvi ndizvo cyclic. Totaura pokuti plunger kunotanga Ronda kwayo zvakare.

Performance zvinodiwa

Hangaiwa plunger jekiseni kupomba Bosch - a mashandiro kuti kunoda kutarisirwa chaizvo panguva oparesheni. Zvikurukuru, nezvezvitadzo kunaka mafuta akashandiswa. In mashandiro, kuti plunger ungano haabatanidzi pamberi mvura uye guruva inoramba iri mafuta. Nei mashandiro ichi kuti yakakwirira zvinoda zvakadai? Ndicho nyore chaizvo. Kana mvura zvikanzwika kushanda plunger uye ruoko Nechepamusoro, lubricating firimu anorasikirwa kuvimbika kwayo. Somugumisiro, mvongamupopoto simba vaviri zvinhu kunowedzera. Izvi zvinotungamirira kupisa kwaizotevera deformation zvikamu. Panyaya tudonhwe muguruva, izvo zvinogona kukonzera mashandiro achikanganisa pamusoro plunger gungano. Mushure kushanda musiyano pakati humburumbira uye pisitoni ndiyo 0,0018 millimeter. Hazvina zviripo nguva rokuongorora zvikamu kudzivisa rokusamhanyira kukundikana kwavo. Kuonawo kuti pombi plunger vaviri 4d56 kuchinja dzakaoma. Izvi imhaka yakakwirira nemazvo zvaAtemisi zvikamu.

Details pamusoro mhosva

Kakawanda kuremara - vanosvotwa of plunger iri humburumbira. How rokuongorora kuti mashandiro? Kuti tione ichi nokuvatema plunger akasiyana zvinzvimbo kana kugadzwa maviri angled madhigirii 45. Kuvapo pamusoro nokushanda pamusoro ngura kunotungamirira kurasikirwa chisimbiso. dambudziko iri rave kugadziriswa perekomplektovkoy mashandiro. How kuzviita? Sleeve uye plunger gaya kuti pose roughness kuti 0.1 microns. Bvumidzwa taper haafaniri kupfuudza 0,4 microns uye ovality - 0.2 microns. Uyezve hwemvura jekiseni pombi plunger wakaputsika muzvikwata kukura pamwe penguva 4 microns. Details vanosarudzwa nokuda nhengo dzisimbe. Pashure vachikuya mashandiro kusukwa peturu uye dzakaunganidza shure.

Zvinotevera zvikanganiso - flaking kana chipping panguva mawindo. It angaperekedzwa scratching, scuffing uye kuwedzera dhayamita yacho Inlet pachiteshi. Panyaya iyi, kuti akayera kusakara pamusoro pechiso ruoko. Kuziva taper uye denderedzwa maburi. Kana parameter kwakarasika, kuti chinhu anofanira kutsiviwa. Chipping kana flaking simbi - zvakakanganisika kuti Haigoni kudzoswa. Sei pachena kukundikana plunger pombi vaviri? Ndezvipi zvinogona tsunga kuderedza injini simba uye kwakawedzera mafuta rinodyiwa. Uyewo, pane kusagadzikana kushanda injini idling.

mhedziso

Saka, takazoziva chii plunger vaviri. Hazvina chinokosha chinotsva pombi, Diesel michini, iyo inoshanda pasi kumusoro kumanikidzwa uye chaanovapa chinotsva dzakakwirira nemazvo. Zvinodiwa kuvhiyiwa - zviri yepamusoro mafuta. In nokushanda plunger nezvakwakaipira sei mvura uye tsvina, izvo Inowedzera kuti ngura kwacho uye kunoita kuti chimiro cheek.
