Udindo wa injini yozizira dongosolo

Dongosolo lozizira limapangidwa kuti liteteze injini kuti isatenthedwe komanso kutenthedwa.Kutentha kwambiri ndi kutentha pang'ono kumapangitsa kuti chilolezo chanthawi zonse cha magawo osuntha a injini chiwonongeke, kutentha kwa mafuta kumasokonekera, kufulumizitsa kuvala kwa injini.Kutentha kwambiri kwa injini kungayambitse kuwira koziziritsa, kuchepetsa kwambiri kutentha kwa kutentha, kuyaka msanga kwa osakaniza, komanso kugunda kwa injini, komwe kumatha kuwononga zida za injini monga mutu wa silinda, ma valve ndi ma pistoni.Kutentha kwa injini ndikotsika kwambiri, kungayambitse kuyaka kosakwanira, kuchuluka kwa mafuta, moyo wautumiki wa injini umachepetsedwa.

Mapangidwe a makina oziziritsira injini

1. Radiator

Radiator nthawi zambiri imayikidwa kutsogolo kwa galimotoyo, pamene galimoto ikuyenda, mpweya wotentha womwe ukubwera umayenda nthawi zonse kudzera pa radiator, ndikuchotsa kutentha kwa choziziritsa kukhosi, kuonetsetsa kuti kutentha kwabwino kumataya.

Rediyeta ndi chotenthetsera chomwe chimagawanitsa choziziritsa kutentha kwambiri chomwe chikuyenda kuchokera mu jekete lamadzi lamutu la silinda kupita ku mitsinje yaying'ono yambiri kuti muwonjezere malo ozizira ndikufulumizitsa kuzizira kwake. gawo la radiator.Choziziritsa kutentha kwambiri chimasamutsa kutentha ndi mpweya wochepa kwambiri kuti ukwaniritse kusinthana kwa kutentha.Kuti mupeze zotsatira zabwino zowononga kutentha, radiator imagwira ntchito ndi fani yozizirira.Choziziriracho chikadutsa pa radiator, kutentha kwake kumatha kuchepetsedwa ndi 10 ~ 15 ℃.

2, thanki yowonjezera madzi

Tanki yokulirapo nthawi zambiri imapangidwa ndi pulasitiki yowonekera kuti iwonetse kuzizira kwake mkati.Ntchito yaikulu ya thanki yowonjezera ndikupereka malo kuti chozizirirapo chiwonjezeke ndi kugwirizanitsa, komanso malo otsekemera apakati pazitsulo zoziziritsira, choncho amaikidwa pamalo apamwamba kwambiri kusiyana ndi njira zina zoziziritsira.

3. Kuzizira fani

Mafanizi ozizira nthawi zambiri amaikidwa kumbuyo kwa radiator.Chotenthetsera chozizira chikazungulira, mpweya umayamwa kudzera pa radiator kuti uwonjezere kutentha kwa radiator ndikufulumizitsa kuzizira kwa choziziritsa.

Kumayambiriro kwa ntchito ya injini kapena kutentha kochepa, chowotcha chozizira chamagetsi sichigwira ntchito.Pamene chojambulira cha kutentha kozizira chiwona kuti kutentha kozizira kumaposa mtengo wina, ECM imayendetsa ntchito ya injini ya fan.

Ntchito ndi kapangidwe kake ka makina ozizira a injini

4, thermostat

Thermostat ndi valavu yomwe imayang'anira kayendedwe ka kozizira.Imatsegula kapena kutseka njira ya choziziritsira ku radiator molingana ndi kutentha kwa choziziritsira.Injini ikayamba kuzizira, kutentha kwa choziziritsa kuzizira kumakhala kochepa, ndipo chotenthetsera chimatseka njira ya choziziritsira chozizira kupita ku radiator.Choziziriracho chimabwereranso ku silinda ndi jekete lamadzi lamutu la silinda kudzera pa mpope wamadzi, kuti chozizirirapo chizitenthetsa msanga.Kutentha kozizirirako kukakwera kufika pamtengo wakutiwakuti, chotenthetsera chimatsegula njira kuti chozizirirapo chiziyenda ku rediyeta, ndipo choziziritsa kukhosi chimabwereranso ku mpope pambuyo poziziritsidwa ndi radiator.

Thermostat yamainjini ambiri imakhala pamzere wa silinda wamutu wakutulutsira.Kukonzekera kumeneku kuli ndi ubwino wa dongosolo losavuta.M'mainjini ena, thermostat imayikidwa pamalo olowera madzi a mpope.Kapangidwe kameneka kamalepheretsa kutentha kozizira mu silinda ya injini kuti isagwe kwambiri, motero kumachepetsa kusintha kwa kupsinjika kwa injini ndikupewa kuwonongeka kwa injini.

5, pompa madzi

Injini yamagalimoto nthawi zambiri imatenga pampu yamadzi ya centrifugal, yomwe ili ndi mawonekedwe osavuta, kukula kochepa, kusamuka kwakukulu komanso ntchito yodalirika.Pampu yamadzi ya centrifugal imakhala ndi chipolopolo ndi choyikapo choziziritsa kulowera komanso njira zotulutsira.Ma axle amatsamba amathandizidwa ndi chimodzi kapena zingapo zomata zomwe sizikufuna mafuta.Kugwiritsa ntchito ma bearings osindikizidwa kungalepheretse kutayikira kwamafuta ndi dothi ndi kulowa kwamadzi.Chipolopolo cha mpope chimayikidwa pa cylinder block ya injini, choyikapo pampu chimakhazikika pa shaft ya pampu, ndipo pampu ya pampu imalumikizidwa ndi manja amadzi a silinda.Ntchito ya mpope ndikukakamiza choziziritsa kuziziritsa ndikuwonetsetsa kuti chimayenda kudzera munjira yozizira.

6. thanki yamadzi yotentha

Magalimoto ambiri ali ndi makina otenthetsera omwe amapereka kutentha kwa injini.Mpweya wotenthawu uli ndi chotenthetsera, chomwe chimatchedwanso thanki yamadzi otentha, yomwe imapangidwa ndi mapaipi amadzi ndi zidutswa za radiator, ndipo mbali zonse ziwiri zimalumikizidwa ndi njira yoziziritsira komanso polowera.Choziziritsa kutentha kwambiri cha injiniyo chimalowa mu thanki ya mpweya wotentha, chimatenthetsa mpweya wodutsa mu thanki ya mpweya wotentha, ndi kubwerera ku makina ozizira a injini.

7. Zoziziritsa

Galimotoyo imayendetsa m'malo osiyanasiyana, nthawi zambiri imafunika kuti galimoto yomwe ili mu kutentha kwa -40 ~ 40 ℃ igwire ntchito moyenera, kotero choziziritsa cha injini chiyenera kukhala ndi malo ozizirirapo otsika komanso malo otentha kwambiri.

Chozizira ndi chisakanizo cha madzi ofewa, antifreeze ndi zowonjezera zochepa.Madzi ofewa alibe (kapena amakhala ndi) ma calcium osungunuka ndi ma magnesium osungunuka, omwe amatha kuletsa makulitsidwe ndikuwonetsetsa kuziziritsa.Antifreeze sangalepheretse kuzizira kozizira munyengo yozizira, kupewa radiator, cylinder block, silinda mutu kutupa mng'alu, komanso moyenerera kumapangitsa kuwira kwa choziziritsa, kuonetsetsa kuziziritsa.Antifreeze yomwe imagwiritsidwa ntchito kwambiri ndi ethylene glycol, yopanda mtundu, yowonekera, yokoma pang'ono, hygroscopic, viscous yamadzimadzi yomwe imasungunuka ndi madzi mwanjira iliyonse.Choziziracho chimawonjezeredwa ndi dzimbiri inhibitor, foam inhibitor, bactericidal fungicide, pH regulator, colorant ndi zina zotero.
