Ukugcinwa kwe-excavator yasehlobo, gcina kude namaphutha okushisa aphezulu -irediyetha
Indawo yokusebenza yama-excavators inokhahlo, futhi amazinga okushisa aphezulu angathinta ukusebenza komshini. Kodwa-ke, lapho izinga lokushisa liqinile, lingaphinde lithinte impilo yesevisi yomshini. Izinga lokushisa elisebenzayo libalulekile kubavubukuli. Ukukhiqiza ukushisa kwama-excavators ngokuyinhloko kuthatha amafomu alandelayo:
Ukushisa okukhiqizwa ukushiswa kukaphethiloli wenjini engu-01;
02 Uwoyela weHydraulic ukhiqiza ukushisa okungaguqulwa kube amandla okucindezela ohlelweni lwe-hydraulic;
03 Ukushisa kwe-Friction okukhiqizwa ukudluliswa kwe-hydraulic nokunye ukudluliselwa ngesikhathi sokunyakaza;
04 Ukushisa kwelanga.
Phakathi kwemithombo yokushisa eyinhloko yezinto ezimbiwayo, ukushiswa kukaphethiloli wenjini cishe kulinganiselwa ku-73%, amandla asebenza ngamanzi kanye nokudluliswa kwamanzi kukhiqiza cishe u-25%, kanti ukukhanya kwelanga kukhiqiza cishe u-2%.
Njengoba ihlobo elishisayo lisondela, ake sazi ama-radiator ayinhloko kuma-excavators:
① Irediyetha epholile
Umsebenzi: Ngokulawula izinga lokushisa le-antifreeze emaphakathi yenjini ngomoya, injini ingasebenza ngaphakathi kwebanga lokushisa elifanele ngaphansi kwezimo zokusebenza ezihlukene, ivimbele ukushisisa noma ukupholisa ngokweqile.
Umphumela: Uma ukushisa ngokweqile kwenzeka, izingxenye ezihambayo zenjini zizokhula ngenxa yokushisa okuphezulu, okubangela ukulimala kokuvunyelwa kwazo okujwayelekile kokukhwelana, okuholela ekuhlulekeni nasekujameni emazingeni okushisa aphezulu; Amandla omshini wengxenye ngayinye ayancishiswa noma awonakaliswe ngenxa yokushisa okuphezulu; Ngesikhathi sokusebenza kwenjini, izinga lokushisa eliphezulu lingaholela ekwehleni kwevolumu yokudonsa ngisho nokusha okungavamile, okuholela ekunciphiseni kwamandla enjini kanye nezinkomba zezomnotho. Ngakho-ke, injini ayikwazi ukusebenza ngaphansi kwezimo ezishisa ngokweqile. Uma kubanda kakhulu, ukulahlekelwa kokushiswa kokushisa kuyanda, i-viscosity yamafutha iphezulu, futhi ukulahlekelwa kwamandla okushayisana kukhulu, okuholela ekunciphiseni kwamandla enjini kanye nezinkomba zezomnotho. Ngakho-ke, injini ayikwazi ukusebenza ngaphansi kwezimo ze-subcooled.
② Irediyetha kawoyela weHydraulic
Umsebenzi: Ngokusebenzisa umoya, izinga lokushisa likawoyela we-hydraulic lingalinganiswa phakathi kwebanga elifanele ngesikhathi sokusebenza okuqhubekayo, futhi uhlelo lwe-hydraulic lungakwazi ukushisa ngokushesha lapho lufakwa esimweni esibandayo, lufinyelele izinga lokushisa elivamile lokusebenza lamafutha we-hydraulic.
Umthelela: Ukusebenzisa uhlelo lwe-hydraulic emazingeni okushisa aphakeme ngokweqile kungabangela uwoyela we-hydraulic ukuba wonane, ukhiqize izinsalela zikawoyela, futhi kubangele ukumbozwa kwezingxenye ze-hydraulic, okungaholela ekuvinjweni kwe-throttle port. Lapho izinga lokushisa likhuphuka, i-viscosity kanye ne-lubricity yamafutha we-hydraulic izokwehla, okuzonciphisa kakhulu impilo yokusebenza yezingxenye ze-hydraulic. Izigxivizo, ama-filler, ama-hoses, izihlungi zikawoyela, nezinye izakhi ezinhlelweni ze-hydraulic zinebanga elithile lokushisa lokusebenza. Ukushisa kwamafutha okweqile emafutheni we-hydraulic kungasheshisa ukuguga nokwehluleka kwabo. Ngakho-ke, kubalulekile ukusebenzisa uhlelo lwe-hydraulic ekushiseni okusethiwe okusebenzayo.
③ I-Intercooler
Umsebenzi: Ukupholisa umoya othathayo onezinga lokushisa eliphezulu ngemva kokushaja i-turbo kuya kumazinga okushisa aphansi ngokwanele ngomoya ukuze kuhlangatshezwane nezidingo zemithetho yokukhipha umoya, kuyilapho kuthuthukisa ukusebenza kwamandla enjini nomnotho.
Umthelela: I-turbocharger ishayelwa igesi yokukhipha injini, futhi izinga lokushisa le-exhaust lenjini lifinyelela izinkulungwane zamadigri. Ukushisa kudluliselwa ohlangothini lwe-turbocharger, okwenza izinga lokushisa lokuthathayo likhuphuke. Umoya ocindezelwe nge-turbocharger nawo udala ukuthi izinga lokushisa lokungenisa likhuphuke. Izinga lokushisa eliphezulu lomoya ongenisayo lingabangela ukuqhunyiswa kwenjini, kubangele imiphumela engemihle njengomphumela oncishisiwe we-turbocharging kanye nempilo yenjini emfishane.
④ I-condenser ye-air conditioning
Umsebenzi: I-high-temperature ne-high-pressure refrigerant gas esuka ku-compressor iyaphoqeleka ukuthi incibilike futhi ibe uketshezi olunezinga lokushisa eliphezulu kanye nomfutho ophezulu ngokupholiswa yisiphepho serediyetha noma ifeni ye-condenser.
