Umsebenzi oyinhloko wepayipi lamanzi elingaphezulu lethangi lamanzi lemoto
Ipayipi lamanzi elingaphezulu lethangi lamanzi lemoto "liyi-artery" yesistimu yokupholisa injini, edlala izindima eziningi ezibalulekile ekugcineni izinga lokushisa elijwayelekile lokusebenza kwenjini. Okokuqala, liyisiteshi sokulethwa esikhethekile se-coolant eshisa kakhulu. Ipayipi lixhumanisa indawo yokungena kwamanzi enjini kolunye uhlangothi kanye nengxenye ephezulu yethangi lamanzi kolunye uhlangothi. Lapho izinga lokushisa lamanzi enjini lenyuka laya ku-80 - 90℃, i-thermostat ivula imodi yokujikeleza okukhulu, kanti i-coolant emazingeni okushisa angu-90 - 95℃ izogeleza ngokushesha ethangini lamanzi ngaleli payipi, ilungiselela inqubo elandelayo yokushabalalisa ukushisa. Izinga lokugeleza kwe-coolant yangaphakathi lingafinyelela ku-8 - 12L/ngomzuzu, liqhuba kahle inani elikhulu lokushisa elikhiqizwa yinjini. Okwesibili, lithatha umthwalo wemfanelo wokulawulwa kwesikhungo sokucindezela. Leli payipi kufanele limelane nengcindezi eyinhloko yesistimu yokupholisa esukela ku-1.1 - 1.5bar, futhi lixhunywe nethangi lamanzi lokukhulisa ukulawula ngokunembile ingcindezi yesistimu, ligweme ukuqhuma kwepayipi ngenxa yengcindezi enkulu noma ukuvaleka komoya okubangelwa ukucindezeleka okunganele. Ukusebenza kwayo kokuvala kuthinta ngqo ukusebenza kahle kwesistimu yokupholisa yonke. Ngaphezu kwalokho, ukwakheka okuhlukile "kokungenisa uketshezi okuphezulu" kusiza ukuthuthukisa ukusebenza kahle kokushabalalisa ukushisa. Lapho uketshezi olushisayo lungena phezulu kwethangi lamanzi, luyahlukana ngokwemvelo futhi lusizwe amandla adonsela phansi ukuze kujikeleze. Lusebenza ngokubambisana namafin okushabalalisa ukushisa kanye nabalandeli be-elekthronikhi ethangini lamanzi. Uma kuqhathaniswa nesistimu efakwe eceleni, ingathuthukisa ukusebenza kahle kokushabalalisa ukushisa cishe ngo-15%. Lokhu kusiza ukwehlisa izinga lokushisa le-coolant ngokushesha futhi kuqinisekiswe ukuthi injini ihlala ngaphakathi kwebanga lokushisa lokusebenza elifanele.
Amaphutha avamile kanye nezixazululo zepayipi lamanzi elingaphezulu lethangi lamanzi lemoto
Ngesikhathi sokusetshenziswa isikhathi eside, ipayipi lamanzi elingaphezulu lethangi lamanzi lemoto lingase lingasebenzi kahle ngenxa yezici ezahlukahlukene, futhi kubalulekile ukulibona nokulilungisa ngokushesha.
Iphutha lokuvuza Lena yinkinga evame kakhulu, futhi izimbangela ziyahlukahluka. Ukuguga kwepayipi kungenye yezizathu eziyinhloko. Uma kuvezwa emazingeni okushisa aphezulu isikhathi eside, izinto zerabha zepayipi zizoqina kancane kancane futhi zibe buthaka, okuholela ekuqhekekeni noma ekulimaleni, okuholela ekuphuzeni kwe-coolant. Kulesi simo, kuyadingeka ukushintsha ipayipi elithembekile nelihambisana nemodeli yemoto ngesikhathi esifanele. Kunconywa ukuthi ulishintshe njalo eminyakeni emi-2 noma amakhilomitha angama-40,000, noma ngabe kuza kuqala. Ukuvalwa okungekuhle endaweni yokuxhuma nakho kungabangela ukuvuza. Isibonelo, ama-clamp akhululekile noma ama-gasket okuvala agugile kanye nawonakele abangela ukuthi indawo yokuxhuma ingalingani kahle, okuvumela i-coolant ukuthi iphume ngezikhala. Ngalesi sikhathi, ama-clamp kufanele aqiniswe, noma ama-gasket okuvala kufanele ashintshwe. Qinisekisa ukuthi indawo yokuxhuma ihlanzekile futhi ayinazo izingcola namabala kawoyela lapho uyifaka ukuze ugcine umphumela omuhle wokuvala. Ngaphezu kwalokho, ukucindezela okukhulu kwethangi lamanzi, njengokushisa ngokweqile kwenjini noma ukwehluleka kohlelo lokupholisa, okubangela ukucindezela kwangaphakathi kudlule ibanga elingamelana nepayipi, noma umonakalo wamandla wangaphandle epayipini obangelwa ukushaywa noma ukuklwebheka kwezinto zangaphandle ngesikhathi sokushayela, nakho kungabangela ukuvuza. Uma ukuvuza kubangelwa ukucindezela okukhulu, kufanele kwenziwe ukuhlolwa okuphelele kohlelo lokupholisa ukuze kutholakale ukwehluleka kwephampu, ukuvinjelwa kwerediyetha, nezinye izinkinga bese kuzilungisa ngokushesha; ngomonakalo wamandla wangaphandle, phatha ngokususelwa ebangeni lomonakalo. Umonakalo omncane ungalungiswa okwesikhashana ngeglue noma iteyipu yobungcweti, kodwa ukuze kuphephe, kungcono ukufaka esikhundleni ipayipi elonakele.
Umehluko ongajwayelekile wokushisa phakathi kwamapayipi amanzi aphezulu naphansi ujwayelekile ngemva kokufudumeza okuzinzile. Umehluko wokushisa phakathi kwamapayipi amanzi aphezulu naphansi kufanele ube phakathi kuka-5 - 15℃. Uma leli banga lidluliwe, kubhekwa njengokungajwayelekile. Uma ipayipi eliphezulu lishisa futhi ipayipi eliphansi lipholile, kungenzeka ukuthi i-thermostat ibambeke esimweni sokuvalwa, futhi i-coolant ijikeleza ngaphakathi kuphela ngendlela encane. Ipayipi eliphezulu liqhubeka limunca ukushisa futhi lishisa uma ulithinta, kuyilapho ipayipi elingezansi, elingahlanganyeli ekujikelezeni kwegazi, lihlala lisezingeni lokushisa eliphansi. Lesi simo sidinga ukuhlolwa okusheshayo kwe-thermostat kanye nokushintshwa kwezingxenye zasefektri zokuqala. Uma umehluko wokushisa kwe-coolant uvela ngemuva kokushintsha i-antifreeze noma ngemuva kokulungiswa, ngokuvamile kungenxa yokuvaleka komoya ohlelweni lokupholisa. Umoya uvimbela ukujikeleza kwe-coolant, okuholela ekusabalaleni kokushisa okungalingani futhi kuhambisane nokushintshashintsha kwezinga lokushisa lamanzi. I-Correct排气 idinga ukusebenza kwemoto ebandayo. Khulula kancane isivalo sethangi le-antifreeze, qala injini ngesivinini esingenzi lutho, bese ulinda ukuthi izinga lokushisa lamanzi likhuphuke. Bese unyathela kancane i-accelerator ukuze ubone amabhamuza ekhishwa ethangini kuze kube yilapho izinga loketshezi lizinzile. I-Manual排气 ayisebenzi, khona-ke ithuluzi lokukhipha i-vacuum lochwepheshe kufanele lisetshenziswe. Ukwehluleka kwephampu yamanzi nakho kungabangela umehluko ongavamile wokushisa. Uma i-impeller yephampu igugile noma ibhande lishelela, kuzoholela ekunganele kwamandla okujikeleza kwe-coolant, okubonakala njengokungabikho kokuguquguquka ezingeni lethangi lamanzi ngemva kokuqala kwenjini ebandayo, kanye nomehluko wokushisa oqhubekayo ongaphezu kuka-15℃ phakathi kwamapayipi amanzi aphezulu naphansi. Ngesikhathi sokuhlolwa, ithangi elivimbela ukubanda lingavulwa ukuze kubonwe ukuthi izinga loketshezi ligeleza njalo ngesivinini esingasebenzi. Uma limile, iphampu yamanzi ingase ibe nephutha. Izimoto ezinamakhilomitha angaphezu kuka-80,000 kufanele zihlolwe njalo ngamaphampu amanzi futhi ama-impeller agugile noma amabhande ashelelayo kufanele ashintshwe ngesikhathi.
Uma ipayipi lamanzi liyisicaba, uma sekutholakale ukuthi ipayipi lamanzi elingaphezulu lethangi lamanzi liyisicaba, ngokuvamile kubonisa ukuthi ithangi lamanzi liyisicaba noma kukhona ukuvaleka. Ukuphelelwa amanzi emzimbeni kwethangi lamanzi kuzokwenza kube nzima ukuthi umoya oshisayo uphume, okubangela ukuba izinga lokushisa lamanzi likhuphuke kakhulu, bese kuthi kamuva ipayipi lamanzi liyisicaba; ukuvaleka kuzophazamisa ukujikeleza kwe-coolant, okubangela ukucindezeleka okungajwayelekile ephayiphini. Ezimweni ezinjalo, kubalulekile ukuvakashela isitolo sokulungisa esingochwepheshe ngokushesha ukuze uhlole uhlelo lokupholisa, uthole imbangela yephutha, futhi ugweme izinkinga ezinkulu njengokushisa ngokweqile kwenjini.
Amaphuzu abalulekile okunakekelwa kwansuku zonke
Ukuze wandise impilo yesevisi yepayipi lamanzi elingaphezulu lethangi lamanzi futhi unciphise ukwenzeka kwamaphutha, ukulungiswa kwansuku zonke kubalulekile. Hlola njalo ukuqina kwepayipi lamanzi kanye nokusebenza kokuvala kwe-interface, naka noma yiziphi izimpawu zokuvuvuka, ukuqhekeka, ukuvuza, njll. kokuguga, futhi unake ngokukhethekile ngesikhathi sokulungiswa kwesizini. Ngesikhathi esifanayo, sebenzisa i-antifreeze yokuqala yefektri, gwema ukugqwala kwepayipi nge-antifreeze engaphansi, futhi ulandele ngokuqinile izinyathelo ezifanele lapho ushintsha i-antifreeze ukuqinisekisa ukuthi umoya ukhishwa ngokuphelele ohlelweni lokupholisa.
