Ukukhetha okokupholisa - uchwepheshe uyeluleka
Umsebenzi oyinhloko wesipholisi ukususa ukushisa enjinini. Kumelwe futhi ivikele uhlelo lokupholisa ekugqwaleni, ukukala kanye ne-cavitation. Kubaluleke kakhulu ukuthi imelane neqhwa,” kubhala uPavel Mastalerek wakwaCastrol.
Ngaphambi kobusika, kufanelekile ukubheka hhayi kuphela izinga lokupholisa (lokhu kufanele kwenziwe cishe kanye ngenyanga), kodwa futhi nezinga lokushisa elibandayo. Esimeni sethu sezulu, uketshezi olunephuzu eliqandayo elicishe libe ngu-35 degrees Celsius luvame ukusetshenziswa kakhulu. Izinto zokupholisa ngokuvamile zingamaphesenti angu-50. emanzini, kanye namaphesenti angu-50. kusuka ku-ethylene noma i-monoethylene glycol. Ukwakheka kwamakhemikhali okunjalo kukuvumela ukuthi ususe ngokuphumelelayo ukushisa enjini ngenkathi ugcina izakhiwo ezidingekayo zokuzivikela.
Bheka futhi: Uhlelo Lokupholisa - Ukushintsha Kwe-Fluid Nokuhlolwa. Umhlahlandlela
Ama-radiator akhiqizwa namuhla asebenzisa ubuchwepheshe obuhlukahlukene. Eyokuqala ubuchwepheshe be-IAT, obuhlanganisa izinhlanganisela ezakha umgoqo wokuvikela kuzo zonke izakhi zesistimu yokupholisa. Zivikela lonke uhlelo ekugqwaleni nasekubunjweni kwesikali. Uketshezi olusebenzisa lobu buchwepheshe ngokushesha lulahlekelwa izakhiwo, ngakho kufanele lushintshwe okungenani kanye njalo eminyakeni emibili, futhi okungcono minyaka yonke.
Uketshezi oluningi lwesimanje lusekelwe kubuchwepheshe be-OAT. Cishe izikhathi ezingamashumi amabili zizacile (uma kuqhathaniswa noketshezi lwe-IAT), ungqimba oluvikelayo ngaphakathi ohlelweni lusiza ukudluliswa kokushisa kokubili kusuka enjini kuya oketshezini futhi kusukela oketshezini kuya ezindongeni zerediyetha. Nokho, uketshezi lwe-OAT alukwazi ukusetshenziswa ezimotweni ezindala ngenxa yokuba khona kwama-lead solders kuma-radiator. Ngenxa yokusetshenziswa kobuchwepheshe be-LongLife kulolu hlobo loketshezi, kungenzeka ukuthi kushintshwe i-reagent njalo ngemva kweminyaka emihlanu. Elinye iqembu uketshezi oluyingxube - HOAT (isibonelo, iCastrol Radicool NF), lisebenzisa lobu buchwepheshe obungenhla. Leli qembu loketshezi lingasetshenziswa esikhundleni soketshezi lwe-IAT.
Ukuhlukahluka koketshezi kuyinkinga enkulu yokunakekela. Uketshezi kubo bonke ubuchwepheshe kuyingxube yamanzi ne-ethylene noma i-monoethylene glycol futhi kuyaxubana. Kodwa-ke, kufanele kukhunjulwe ukuthi izithasiselo ezihlukene zokulwa nokugqwala eziqukethwe ezinhlotsheni ezahlukene zoketshezi zingasabelana, okunciphisa ukusebenza kahle kokuvikela. Lokhu kungaholela futhi ekwakhekeni kwamadiphozithi.
Uma ukugcwalisa kuyadingeka, kucatshangwa ukuthi inani eliphephile loketshezi olungeziwe lifinyelela ku-10%. umthamo wesistimu. Isixazululo esiphephe kunazo zonke siwukusebenzisa uhlobo olulodwa loketshezi, okungcono umakhi oyedwa. Lo mthetho wesithupha uzogwema ukwakheka kodaka kanye nokusabela kwamakhemikhali okungafuneki. I-liquid izophatha ukushisa kahle, ngeke iqhwa futhi izovikela ngokumelene nokugqwala kanye ne-cavitation.
