Kunezinhlobo eziningi zentuthu emnyama evela enjinini, njengokuthi: ①Umshini unentuthu emnyama ngesenzo esisodwa.Iyabhema nje.③Yonke into ijwayelekile uma i-throttle ephezulu isebenza, kodwa ayisebenzi.Uma upaka imoto yejubane izokhipha intuthu emnyama, kube sengathi imoto isibuyile.④320c ayinayo i-intercooler, futhi igiya elingu-5–8 livaliwe Isivinini singaba ngu-250, isenzo sebhakede elingenalutho sigcwele intuthu emnyama, izinga lokushisa likawoyela nezinga lokushisa lamanzi aliphezulu.Ithangi likadizili liyahlanzwa, igridi kaphethiloli iyashintshwa, ipayipi likadizili liyashintshwa, isihlungi somoya siyashintshwa, iphampu yedizili, umlomo wombhobho uyalungiswa, umjikelezo ujwayelekile, futhi ukugeleza kwe-hydraulic yiYehlise, intuthu emnyama. ihlala, ipayipi yokukhipha injini ayinawo umoya, isenzo se-hydraulic siphelile, futhi isivinini siphansi, futhi intuthu emnyama nayo incane.
Ezindaweni zokwakha, sivame ukubona intuthu emnyama evela kubambi.Wonke umuntu uyazi ukuthi ingqikithi yentuthu emnyama evela ezinjinini ayinamandla omlilo okwanele.Izizathu zicishe zihlukaniswe zibe yisistimu yokungenisa umoya engalungile, amandla epompo ye-hydraulic angaphezu kwenjini, kanye nenjini.Ukungasebenzi kahle kwayo, njll.
Akwanele ukwazi isizathu, kufanele sithole isixazululo esiphumelela kakhulu, ngoba intuthu emnyama evela ku-excavator ibonakala iyinkinga encane, kodwa uma ingabhekwanga ngesikhathi, ingase ibangele umshini wokushisa amafutha futhi ngisho nokwenza injini ilimale futhi ilungiswe kabusha.
Isenzo sokwehluleka
1. Isimo sentuthu emnyama esibangelwa ukungena komoya okunganele noma ukuvuza kwepayipi elingenisayo.Ngenxa yokusetshenziswa isikhathi eside kwe-excavator, ukuguga nokulimala kwepayipi lokudonsa kanye ne-clamp yepayipi kuzobangela ukuthi ipayipi livuze, limunce uthuli olukhulu, futhi livimbe isipholile somoya, njll., okuzobangela isenzakalo seNtuthu emnyama. .Uma kwenzeka lolu hlobo lwenkinga, kufanele kubhekwane nalo kusenesikhathi, ngaphandle kwalokho injini izosheshe iguge, noma idonsa amasilinda nokunye ukwehluleka.
2. Uma injini ikhipha intuthu emnyama eningi futhi ukwehla kwamandla kukhulu, kuyadingeka ukuthi kubhekwe ukuthi kukhona ukuvuza kwamafutha epayipini lokungenisa le-turbocharger, isondo le-turbine ye-turbocharger, nokuthi ama-blades aphukile yini. , igugile, noma ikhubazekile., Ukuthi ngabe kunomonakalo wokuklwebheka endlini ye-turbocharger, nokuthi imvume ye-impeller shaft ingaphezu kuka-3 mm.
Uma lezi zenzakalo zenzeka, i-turbocharger kufanele ishintshwe.
3. Hlola ukuthi iphampu yedizili nomjovo kaphethiloli kugugile yini futhi kubangelwa intuthu emnyama.I-excavator isenamandla uma injini ikhipha intuthu emnyama, kodwa ijubane lenjini lizokwehla (ngaphezu kuka-200 rpm).
Lesi simo sibangelwa ikakhulukazi ukwehluleka kwenozi yedizili (ukuhlolwa kwe-cylinder-breaking kungasetshenziswa ukuhlola ikhwalithi yomjovo). uketshezi.Le nto idinga ukuthi kubhekwe iphampu kadizili.
4. Uma i-valve ye-EGR yenjini ilimele noma ibambekile, izophinde ibangele intuthu emnyama.Uma i-valve ye-EGR yehluleka, kuzovela i-alamu esibukweni.Uma iphutha lenzeka, kufanele lishintshwe ngesikhathi, ngaphandle kwalokho lizophazamisa ukusebenza kahle kwenjini, futhi kungaba nomuzwa wokuthi idla uphethiloli omningi kunomsebenzi ovamile.
5. I-excavator iba buthaka uma injini ikhipha intuthu emnyama, futhi kuba nokushintshashintsha komsindo lapho injini isebenza ngaphansi komthwalo.Ngalesi sikhathi, kungenzeka ukuthi amandla epompo ye-hydraulic adlula amandla enjini ukuze abangele intuthu emnyama.Ngalesi sikhathi, qale unciphise ukugeleza nokucindezela kwepompo ye-hydraulic.Uma iphutha lisekhona ngemva kokuba ipompo ye-hydraulic ilungiswe inani elivamile, khona-ke uhlelo lwe-fuel injini kufanele luhlolwe.Uma ukugeleza nokucindezela kwepompo ye-hydraulic kungakwazi kuncishiswe, khona-ke izingxenye zesistimu ye-hydraulic zidinga ukuhlolwa.
Isifinyezo sokwehluleka kwentuthu emnyama yenjini yokumba:
Nakuba ukwenzeka kwentuthu emnyama evela enjinini kunzima kakhulu, ekugcineni, izizathu zokuhluleka yilezi.Lapho uhlola futhi uphatha, kufanele ubhekisise ngokuphelele ukwenzeka kokwehluleka ukuze wenze ukwahlulela okunembe kakhulu.
Uma udinga izesekeli ezihlobene noma i-excavator entsha (i-excavator ye-XCMG, i-SANY excavator, i-KOMATSU excavator, njll), ungasithinta!
