Injini dzekutanga dzemotokari dzainge dzisina chinhu chakakosha icho chatinoona chakakosha nhasi: pombi.Mvura yekutonhodza yemvura yakashandiswa yaive mvura yakachena, yakasanganiswa neinopfuura phenyl doro, kudzivirira kutonhora.Kutenderera kwemvura inotonhorera kunotsamira zvachose pane zvakasikwa chiitiko che thermal convection.Mushure mekunge mvura inotonhorera inotora kupisa kubva kumuviri wehumburumbira, inoyerera ichienda kuchiteshi  uye inopinda mumucheto we radiator;Sezvo mvura inotonhorera inotonhora, inongonyura pasi peradiyeta uye muchikamu chepasi checylinder block.Uchishandisa iyi thermosiphon musimboti, kutonhora kunogona kutadza kuitwa.Asi munguva pfupi yapfuura,  pombi dzemvura dzakawedzerwa kune inotonhodza kuti mvura inotonhora ifambe nekukasira.

Iyo yekutonhodza sisitimu yeinjini yemotokari yemazuva ano  kazhinji inotora centrifugal mvura pombi.Nzvimbo inonzwisisika yekuisa nzvimbo yepombi iri pasi pegadziriro yekutonhora, asi  chikamu chepombi chinoiswa pakati pegadziriro yekutonhora, uye nhamba huru yepombi inoiswa pamusoro pejini.Iyo pombi yakaiswa pamusoro peinjini inowanzoitika kune cavitation.Hazvina mhosva kuti iri pachinzvimbo chipi, mvura yepombi yepombi , seNaitai V8 injini yepombi mvura, sipidhi isingaite ingangoita 750L/h, inosvika pakumhanya kunosvika 12000L/h.

Kubva pakuona kwehupenyu hwesevhisi, shanduko yakakosha pakugadzira pombi  ndeyekuti zvisimbiso zveceramic zvakaonekwa makore mashoma apfuura.Kuenzaniswa nemasimbiso erubha kana zvisimbiso zvematehwe zvakamboshandiswa kare, zvisimbiso zveceramic zvinonyanya kupfeka, asi zvinewo kukanganisa kwekukwenywa nyore nyore nezvidimbu zvakaoma mumvura inotonhora.Kunyange zvazvo kuitira kudzivirira pombi chisimbiso kukundikana mukugadzirwa kwe  kuita kuenderera mberi kwekuvandudza, asi kusvika ikozvino haigoni kuvimbisa kuti chisimbiso chepombi haisi dambudziko. Kana chisimbiso chichinge chabuda, ipapo kuzora kwepombi inotakura kunogezwa.

1. Kuongororwa kwemhosva

Mumakore makumi maviri apfuura, kusimba kwemotokari kwakavandudzwa ne , saka hupenyu hwesevhisi hwepombi dzemvura huri kuramba huchiipisisa here?Kwete hazvo.Mapombi emazuva ano achiri kuda kuchinjwa  huwandu hwebasa, motokari yakatyaira anenge makiromita 100 zviuru, pombi chero nguva pane mukana wekukundikana.

Iyo pombi yekutadza kuongororwa  kazhinji kutaura kuri nyore.Panyaya yekudonha kwemhepo yekutonhodza, munhuwi we thermal antifreeze unogona kunhuwidza, asi zvinofanirwa kutarisa  kuti uone kana mvura inotonhorera iri kubuda kubva papombi shaft chisimbiso.Inogona kushandisa  pamusoro pegirazi diki mwenje kutarisa kana gomba repombi yemvura riri kubuda.Kuti ugare uchigadzirisa, teerera kutarisa kurasikirwa kwetangi remvura inotonhorera.

Kubuda kwepombi ndiko kukanganisa kwenhamba yekutanga kwepombi, ruzha imhosva yechipiri, nekuda kwekukuvadzwa uye kukonzera chiitiko chekurumwa kwepombi shaft kufa, zvakanyanya  ona. Kana ichi chiitiko chikangoitika, radiator ichakuvadzwa mushure memhepo.

Kunyange zvazvo kuora kwakakomba kwepombi yepombi yemvura kunowanzoonekwa mumabhuku ekugadzirisa motokari, asi kana kugadziriswa kwemaitiro kuchiitwa, impeller corrosion haisi chinhu chinowanzoitika .Ukaona tsvuku inotonhorera, ngura ruvara, zvinofungidzirwa kuti dambudziko  impeller corrosion.Panguva ino, iwe unofanirwa kutarisa kutenderera kwepombi inotonhorera, iyo inotonhorera mu radiator inogona kuburitswa  chikamu, kuitira kuti mwero wemvura ungochengetwa mupombi yemvura, uye wozopisa injini, mudziyo wekushisa uri mukati. nzvimbo yakazaruka zvizere.Kutenderera kwemvura kwakanaka kunofanira kuonekwa kana injini iri kushanda pa 3000r / min.Imwe  inogona kuitika dambudziko nderekuti pombi impeller inoonekwa mugomba.

2. Chikonzero chekukundikana

Kana chiri chikonzero chekutadza kwepombi, zvimwe zviremera zvinotenda kuti ne  bhandi dhiraivha zvishongedzo zvakawandisa, kuitira kuti padivi mutoro wechikonzero.Sezvakataurwa ne  nyanzvi dzezvisimbiso, "pane humbowo hwekuti kurira kwezvinamatidzwa zvine midzi yebhandi drive kune frequency yakasiyana, inogona kuparadza chisimbiso chepombi."Imwe  dambudziko rekutadza kwepombi nderekuti tensioning device yebhandi renyoka inoita yakakosha lateral load papombi.Cavitation nderimwe  dambudziko repombi, separutivi rwemvura rwepombi corrosion, saka kazhinji inoiswa nevhavha yekumanikidza redhiyata.Paunenge uchitsiva pombi, zvinokurudzirwa kuti  mitsva ye fan clutch iiswe, sezvo clutch isina kuenzana inogona kukonzera matambudziko nepombi.

Kune nyanzvi dzinoti kupisa kwakanyanya kushaikwa kwekugadzirisa ndiko kunokonzerawo matambudziko epombi.Kana chinotonhodza chikarasikirwa nekuzora chisimbiso , chisimbiso chinogona kutsva.Mukuwedzera, kukundikana kwepombi kunogonawo kuve nekuda kwehutano husina kunaka hwepombi pachayo.

3. Sayenzi yemabhandi

Iyo yekare modhi  kazhinji inotora bhandi rakajairwa rakaita V, nepo modhi itsva inogona kutora bhandi renyoka.Kana iyo yekare modhi yepombi yakaiswa mune itsva modhi , panogona kuve negwara redambudziko.Nekuti bhandi renyoka rinogona kutyaira pombi yepombi kune yakatarisana neV-bhandi, pombi inotenderera ichienda kune yakatarisana, zvichikonzera kupisa kweinotonhorera.

Iye zvino injini dzakawanda dzinoshandisa bhandi renguva ye nap-camshaft kutyaira pombi yemvura.Chakanakira kuita izvi ndechekuti kana pombi yemvura ikasatenderera, mota haigone kufambiswa, uye inogona kupfupisa injini  degree.Inofanira kusimbiswa kuti bhandi renguva rinofanira kutsiviwa mushure menguva yakakodzera yenguva.Dzimwe nguva unoona izvi  mamiriro ezvinhu.Mukuisa  bhandi idzva renguva mukati menguva diki, pombi yemvura yakakuvadzwa, kazhinji izvi zvinokonzerwa nekuwedzera tension yebhandi.Naizvozvo, paunenge uchiisa  pombi itsva, usachinje zvishoma kune bhandi idzva.

4. Kuchengetedza pombi yemvura

Pano kutaura nezve dambudziko rekutonhodza, uye kugadzirisa  zvimwe zvinhu zvinoda kutarisirwa.Mumotokari dzemazuvano , dzinowanzoshandisa injini yealuminium-yese ine mutoro wepamusoro wekupisa, kushandura chinotonhodza gore rega rega zvinoita senzira yakanaka yekudzivirira matambudziko.Nekudaro, ikozvino iyo antifreeze formula yakakwira zvakanyanya, zvekuti iyo inotonhorera yekutsiva nguva inoramba ichiwedzerwa .Pakutanga, iyo inotonhorera yekutsiva kutenderera yakakurudzirwa kwemakore matatu, ndokuzowedzerwa  kusvika kumakore mana, uye ikozvino GM iri kukurudzira makore mashanu kana 250,000 makiromita pane dzimwe mota.Ikozvino inotonhodza fomula inogona kudzivirira matambudziko anowanzo onekwa muchirongwa chekutonhodza nekuda kwekunonoka kwe  kutsiva kunotonhorera.Chinotonhodza chitsva chinoshingirira pakuora kwemakomisheni ecarboxyl, kureva kuti, silicates, maphosphates  nzira dzemvura dzinovharira zvinhu zvisiri zvehupenyu zvinowanikwa mu glycol.Kunyange zvazvo chinotonhodza chitsva  chinodhura kudarika chinotonhodza chekare, chinokwanisa kuona kuti pombi iri kushanda zvakanaka kwenguva yakareba, saka haidhuri.Kuti ushandise zvakanyanya  life coolant, inotonhodza system inoda kunyatsocheneswa pakuitsiva.

Pano kutaura nezve kunaka kwe antifreeze.Izwi rekuti "antifreeze" harina kutaurwa, nekuti kushandiswa kweantifreeze hakusi kwe  antifreeze chete, asi kunodawo kusaora kwecorrosion, lubrication pump seal kusimudza panovira.Naizvozvo, rudzi rusingazivikanwe antifreeze harufanirwe kushandiswa nekuti runogona kunge rwuine zviwedzere zvisina kufanira  zvinokuvadza pH values.

Iko kukomba kweiyo inotonhora system yekudonha dambudziko haigone kufungidzirwa , izvo hazvingoite kuti mweya wakafemerwa ukuvadze iyo yakafanotemerwa inotonhorera yekuyerera modhi, inotungamira kukugadzirwa kwenzvimbo dzinopisa, asi zvakare kuwedzera kukora kwepombi.

Kana huwandu hwekutonhodza  nguva husina kukwana, zvinokonzeresa kupisa kweinjini, uye nekutaridzika kwekuora kwehutsi, haingokuvadza radiator chete, asiwo inoburitsa mamwe matambudziko epombi.
