Indima ephambili yempompo yamanzi yemoto kunye nendibano yeringi yokutywina
Impompo yamanzi yemoto "yintliziyo" yenkqubo yokupholisa injini, ngelixa iringi yokutywina "ingumlindi othembekileyo" oqinisekisa ukusebenza kwayo okuzinzileyo. Ezi zimbini zisebenza kunye, zikhusela ulungelelwaniso lobushushu benjini kunye.
Ngokwembono yomsebenzi wepompo yamanzi, idlulisela amandla nge-crankshaft yenjini kwaye iqhube i-impeller ukuba ijikeleze ngesantya esiphezulu. Phantsi kwesenzo samandla e-centrifugal, i-coolant itsalwa kwi-radiator kwaye icinezelwe ngaphambi kokuba ipompelwe kwi-water jacket ye-block yesilinda yenjini. I-coolant ifunxa ubushushu obuveliswa kukusebenza kwenjini kwi-block yesilinda ize ibuyele kwi-radiator ukuze iphole. Lo mjikelo uyaphindaphinda, uqinisekisa ukuba injini ihlala isebenza ngaphakathi koluhlu olufanelekileyo lobushushu oluphakathi kwama-85°C - 95°C. Nje ukuba ipompo yamanzi iyeke ukusebenza, i-coolant ayikwazi ukujikeleza, kwaye ubushushu benjini buya kunyuka ngexesha elifutshane. Kancinci, iya kubangela i-alamu yobushushu obuphezulu; kakhulu, inokubangela iimpazamo ezibulalayo ezifana ne-piston etsala isilinda okanye i-block yesilinda iqhekeke.
Indandatho yokutywina, njengecandelo eliphambili lokutywina kwimpompo yamanzi, izalisekisa ikakhulu imisebenzi emibini emikhulu. Okokuqala, ithintela ukuvuza kwe-coolant, enamathela ngokuqinileyo kwiindawo zonxibelelwano phakathi kwendlu yepompo, i-impeller, kunye ne-shaft, ivala indlela yokuba i-coolant ivuze ngaphandle, iqinisekisa uzinzo loxinzelelo kwinkqubo yokupholisa kunye nokunikezelwa okwaneleyo kwe-coolant. Okwesibini, iyahlula ukungcola kunye ne-grease yokuthambisa, ithintela uthuli lwangaphandle kunye nesanti ukuba ingangeni ngaphakathi kwipompo kwaye igugise izinto, kunye nokuthintela umxube kunye ne-emulsification ye-grease yokuthambisa kunye ne-coolant, igcina isiphumo sokuthambisa seebheringi kwaye yandise ubomi benkonzo yepompo.
Izizathu Eziqhelekileyo Zeziphene kunye Neempawu Zazo
Ukungasebenzi kakuhle kwepompo yamanzi
Umonakalo we-impeller: Ukusebenzisa i-coolant ekumgangatho ophantsi ixesha elide okanye ukungaphumeleli ukutshintsha i-coolant ngexesha elifanelekileyo kuya kubangela ukuba izongezo kwi-coolant ziphele, nto leyo ekhokelela ekwandeni kokugqwala kwangaphakathi. Umphezulu we-impeller uya kuba nomhlwa, imingxunya, okanye ukwaphuka kweeblade. Emva kokuba i-impeller yonakele, ukusebenza kakuhle kokujikeleza kwe-coolant kuya kuncipha kakhulu, okubangela ukunyuka okungaqhelekanga kobushushu bamanzi enjini. Isalathisi sokulinganisa ubushushu bamanzi kwideshibhodi siya kunyuka ngokukhawuleza siye kwindawo ebomvu, kwaye kwiimeko ezinzima, kunokubakho imeko "yokubila" kwe-coolant.
Ukuguguleka kweebheringi: Ukuba igrisi yokuthambisa ayanelanga okanye i-coolant ivuza kwigumbi lokuthwala ngexesha lokusebenza kwepompo ngesantya esiphezulu ixesha elide, kuya kubangela ukuba iibhola eziqengqelekayo zeebheringi ziguguleke kwaye indawo evulekileyo ibe nkulu kakhulu. Ngeli xesha, kuya kubakho iingxolo "ezivuthuzayo" okanye "ezivakalayo" kwindawo yenjini, ngakumbi xa isantya singasebenzi. Xa i-accelerator icinezelwe, ingxolo iya kutshintsha ngesantya sokujikeleza. Ukuguguleka okugqithisileyo kweebheringi kuya kubangela ukuba i-shaft yepompo inyikime, nto leyo eyandisa ngakumbi ukungqubana phakathi kwe-impeller kunye ne-housing.
Iingxaki zePulley: Ukuba ipulley yenjini eqhuba ipompo yamanzi iqinile kakhulu, iya kwandisa umthwalo kwi-pump shaft, ikhawulezise ukuguguleka kweebheringi kunye ne-impeller; ukuba ikhululekile kakhulu, iya kutyibilika, nto leyo ebangela isantya sepump esinganelanga kunye nesantya sokujikeleza kwe-coolant esicothayo. Ukubonakaliswa okucacileyo kokungasebenzi kakuhle kwepulley kukuguquguquka okungaqhelekanga kubushushu bamanzi, apho ubushushu bamanzi bunyuka kancinci emva kokuqala kokubanda kwaye butshintshatshintsha ngexesha lokuqhuba.
Ukungaphumeleli kwendandatho yokutywina
Eyona nto ixhaphakileyo yokusilela kweringi yokutywina kukuguga. Njengoko imoto iguga, izinto zeringi yokutywina ziya kulahlekelwa kancinci kancinci, nto leyo ebangela ukwehla kokusebenza kokutywina, kwaye i-coolant iqala ukuvuza kwiindawo zonxibelelwano phakathi kwepompo kunye nenjini okanye i-shaft seal. Ukuba umhlaba ubonisa imikhondo ye-coolant epinki okanye eluhlaza kwaye inqanaba le-coolant kwitanki yokwandisa lihlala lihla, kusenokwenzeka ukuba iringi yokutywina ayiphumelelanga. Ukongeza, indlela ekonakalisa ngayo i-coolant engaphantsi iya kukhawulezisa ukuguga kweringi yokutywina, kwaye ukusetyenziswa okungafanelekanga kweglu yokutywina ngexesha lokufakwa, njengokusetyenziswa kakhulu okanye ukusetyenziswa okungalinganiyo, kunokukhokelela kwiingxaki zokuvalwa nokuvuza okubi.
Iingcebiso zokuthintela iimpazamo kunye nokulungisa
Ukunciphisa umngcipheko weziphene kwi-pump kunye ne-sealing ring assembly, abanini beemoto kufuneka benze ulondolozo rhoqo. Okokuqala, landela ngokungqongqo iimfuno zesandla sesithuthi zokutshintsha i-coolant esemgangathweni rhoqo emva kweminyaka emi-2 okanye iikhilomitha ezingama-40,000 ukuze uphephe ukusebenzisa iimveliso eziphantsi; okwesibini, jonga rhoqo uxinezeleko kunye nokuguguleka kwebhanti ye-pulley yenjini, kwaye uyitshintshe ngexesha ukuba kufunyenwe imifantu okanye ukuthamba; kwangaxeshanye, qaphela ukuba kukho imikhondo yokuvuza kwe-coolant ejikeleze ipompo ngexesha lolondolozo ngalunye kwaye umamele naziphi na iingxolo ezingaqhelekanga kwindawo yenjini.
Ukuba kukho impazamo, kufuneka ilungiswe ngokukhawuleza. Ukuze kubekho ukuvuza kweringi yokutywina, ukutshintsha nje imodeli efanayo yeringi yokutywina esemgangathweni ophezulu kunokusombulula ingxaki; ukuba i-impeller yepompo yonakele okanye iibheringi zigugile kakhulu, ngokuqhelekileyo indibano yepompo kufuneka itshintshwe. Xa kulungiswa, kucetyiswa ukuba ukhethe iziko lokulungisa elithembekileyo ukuqinisekisa umgangatho weendawo kunye nenkqubo yokufakela, ukuthintela ukuphinda kwenzeke kwempazamo ngenxa yokulungiswa okungafanelekanga.
