Impompo yamanzi ingena ngaphambili kwi-injini yemoto.Igcina isisipholisi sijikeleza ukuze sihlale injini kubushushu obufanelekileyo bokusebenza.Ngokwenyani kufuneka ibizwe njengempompo yokupholisa kuba kufuneka impompe umxube wama-50% wokupholisa kunye nama-50% amanzi ngokuxhomekeke kwimozulu.
Kutheni sifuna inkqubo yokupholisa
Ubushushu obufanelekileyo bokusebenza kwi-injini bumalunga nama-200℉, okanye ama-90℃.Eli qondo lobushushu lishushu ngokwaneleyo ukuhamba kakuhle kwe-oyile, kunye nokutsha okumnandi kwi-cylinder, ngelixa lingekho shushu kangangokuba i-injini inokonakala uthenge ubushushu.Nangona kunjalo xa injini isebenza, ubushushu buya kuba phezulu kakhulu kunoko.Ngoko ke iindawo ze-injini ezikufutshane nenkqubo yokutsha kufuneka zipholiswe kwaye yiyo loo nto sifuna inkqubo yokupholisa.
Inkqubo yokupholisa, enesiqhelo iphantse ibe nolwakhiwo olufanayo, kwaye isebenza ngendlela efanayo mhlawumbi isebenza kuyo yonke isithuthi oza kuhlangana naso.
Isebenza njani into yokupholisa
Isipholisa, esingumxube wamanzi kunye ne-ethylene glycol, sisetyenziselwa ukuthwala ubushushu kude nezona ndawo zishushu ze-injini bubukhuphele kwiradiyetha apho bupholiswa khona.
Xa i-injini ikwiqondo lobushushu bokusebenza, isisipholisi esibandayo siyatsalwa kumzantsi weradiyetha ngempompo, emva koko simpontshelwe ngaphambili kwibloko ye-injini.Ijikeleza isilinda, iye phezulu entloko apho ipholisa ivalve ize ibuye iphume kwintloko yesilinda iye kwi radiator ukuze ipholiswe phantsi.
Kwintloko yesilinda esingaphakathi, kukho ivalve yethermostat efana nevalve elawulwa ngamaqondo obushushu ekwaziyo ukulawula ukuhamba kwesipholisi ukuya kwiradiyetha.Xa i-injini ibanda, i-thermostat iyavalwa kwaye amanzi ahlala ngaphakathi kwinkqubo ye-injini de ifudumale.Nje ukuba eso sisipholisi sifikelele kwiqondo lobushushu, i-thermostat iyavuleka, ukuze isisipholisi sikwazi ukuhamba yonke indlela sijikeleze iradiyetha apho sipholiswa kukuhamba komoya wokuqhuba kwisithuthi.
Isebenza njani impompo yamanzi
Impompo yamanzi esebenza ngoomatshini iqulathe la malungu alandelayo: indlu, i-impeller, i-bearing assembly, itywina, njl.njl. Igcina isisipholisi kumjikelezo we-injini.
Impompo ingena ngaphambili kwi-injini, kwaye idibana nepuli eqhutywa libhanti elisuka kwi-crankshaft.Ibhanti efanayo iphinda iqhube i-alternator.Ngoku ezinye iipompo zamanzi ziqhutywa yibhanti yexesha, okanye ngokuthe ngqo kwi-camshaft okanye i-crankshaft.Kungakhathaliseki ukuba iqhutywa njani, impompo yamanzi inoqhagamshelwano olusuka kwi-crankshaft ngebhanti.Oko kuthetha ukuba xa injini isebenza, impompo yamanzi nayo iyasebenza.
Xa i-injini ibanda, i-thermostat iyavalwa kwaye isisipholisi asidluli kwiradiyetha kodwa kusafuneka sijikelezise eso sisipholisi ngaphakathi kwi-injini ukuze kubekho isifudumezi esilinganayo ngaphakathi.Ngoko ke, impompo yamanzi isoloko impompa.
Iinxalenye zempompo yamanzi
Ngoku, makhe sijonge iinxalenye zempompo yamanzi.Ngokubhekiselele kumacandelo, indlu yempompo yenziwe kwi-aluminium ephosiweyo kwaye akukho nto ikhethekileyo.
Embindini wempompo, yishafti ehamba kwindlu.Kwelinye icala, kukho iflange ekhwela kwipulley.Le pulley incanyathiselwe kwibhanti ehamba kwi crankshaft.Yiloo nto eqhuba impompo.Kwelinye icala lempompo, sisishukumisi esihlala ngaphakathi kumngxuma we-injini.Isisipholisi singena empompeni apha, ngesiziba sempompo yamanzi esidityaniswe kumazantsi eradiyetha.
Isipholisi sitsalwa phezulu kwaye singene kumbindi we-impeller ecaleni kweli jelo.Emva koko i-impeller inamacangca ajikelezisa ulwelo ngeenxa zonke, iluphose ngaphandle kwaye yenze indawo yoxinzelelo olusezantsi embindini etsala ukupholisa ngakumbi.
Oku kubizwa ngokuba yimpompo ye-centrifugal impeller.Kanye kufutshane ne-impeller, kwizindlu zempompo, kukho imilo ejikelezayo ephoswe kwimpompo yamanzi kwaye leyo ibizwa ngokuba yi-volute mhlawumbi.Ubume beli volute yinto eyenza uxinzelelo olutsala amanzi kwimpompo.Ukudityaniswa kwe-volute kunye nale pleyiti evala i-impeller, idala indlela evaliweyo yokupholisa endaweni yokuyilahla nje ngokungaqhelekanga.
Namhlanje, iimpompo zamanzi zinamandla amangalisayo.Impompo yobukhulu obuqhelekileyo iya kukhupha ichibi lokuqubha elincinane malunga neyure, kwaye ngesantya esiphezulu se-injini oku kuya kujikeleza sonke isisipholisi sokujikeleza i-injini amaxesha angama-20 ngomzuzu ngamnye.
Ixesha lokutshintsha impompo yamanzi
Iimpompo zamanzi zitywinwe ubomi bonke, kwaye zitshintshwa njengeyunithi epheleleyo, yenziwa ngokubanzi ngaxeshanye njengoko ibhanti lexesha litshintshwa ngenxa yokuba kufuneka ukhulule izinto ezininzi ukuze ungene apha.Iimpompo zamanzi yinxalenye engabizi kakhulu ukuyithenga, kodwa kubiza kakhulu emsebenzini ukuzibuyisela.
Awusoze usebenze ngaphakathi kwimpompo yamanzi kuba ivalwe ubomi bonke kwaye iphathwa njengento esetyenziswayo.Xa impompo ifuna ukutshintshwa, kufuneka ubuyisele le yunithi yonke ngaphandle kwepulley.
Ukuba sijonga kwimpompo yamanzi esebenza ngoomatshini, sinokubona ishafti, okanye intambo yokusonta, ijikwa yipuli.Ngaphambili kukho impompo yamanzi.Olu luhlobo olukhethekileyo lokuthwala ngenxa yokuba lufakwe ngokuthe ngqo kwi-shaft kwaye sesona sizathu sokuba le nto ithathelwe indawo njengeyunithi yonke.
Ibherethi ithambisa kumzi-mveliso ngegrisi.Ayikuyeki ukupholisa ekuvuzeni ecaleni kweshafti, enyanisweni nawaphi na amanzi angena kwibheringi ziindaba ezoyikekayo.
Ngasemva ecaleni kweshafti, sinetywina lomatshini, elisingise kwi-impeller.Ukutywina ishaft ejikelezayo kulwelo olucinezelekileyo bekusoloko kulucelomngeni.Itywina lomatshini apha lihle kakhulu.Iquka ubuso obubini obucinezelwe ngokusondelene kakhulu ngumthombo.Kwaye bahlulwe kwaye bathanjiswa yifilimu encinci ye-coolant.Umsantsa phakathi kwawo omalunga ne-micron, eyiwaka le-millimeter, ebanzi ngokwaneleyo ukuba iqulathe ifilimu emileyo ye-lubricant, kodwa ayibanzi kangangokuba i-lubricant inokuhamba ngayo.
Ngoku ngokuqinisekileyo ukukhuhlana kuya kubangela ukuba itywina libe shushu, kwaye omnye umphunga uya kwenziwa xa le filimu incinci yolwelo ibila.Ngelixa ngokuqinisekileyo singafuni ukufumana nakuphi na ukupholisa ekuthwaleni.Kuba yophula igrisi kwaye oko kuya kubangela ingxaki enkulu kuthi kamva.
Ngoko ke phakathi kwetywina lomatshini kunye nokuthwala kukho umngxuma omncinci, obizwa ngokuba yi-weep hole.Xa isuntswana lolwelo elenziwa ngokubiliswa kwefilimu kunye netywina lomatshini linokuphuncuka kulo mngxuma ungezantsi komjelo apha, emva koko kule mpompo itsalelwa ngasemva kwimpompo kwaye iyehla imida. kwibhloko yenjini.
Ngoku yinto eqhelekileyo kuba kukho ulwelo olubalekayo apho.Ngalo lonke ixesha, abavelisi bathumela iibhulethini zobugcisa bexelela amagcisa ukuba ayeke ukutshintsha impompo zamanzi ngalo lonke ixesha ebona into yokupholisa ejikeleze umngxuma wokulila kwaye iyinto eqhelekileyo.
Kodwa ukuba kukho ulwelo oluninzi kunye nokupholisa okukhazimlisiweyo apha, ngakumbi ukuba unesipholisi esithontsiza sisuka kwipani yeoyile eyiyo apha ngaphantsi, ngoko ke unokuba nempompo yamanzi avuzayo.
Xa iimpompo zamanzi zivuza, yintoni engahambi kakuhle kuzo?
Ngoku ngokusisiseko impompo yamanzi iya kusilela ngenye yeendlela ezintathu.
1. Ukukhutshwa kwetywina
Xa impompo ivuza isisipholisi, kungenxa yokuba itywina alisebenzi, kwaye loo nto iphantse isoloko ibangelwa kukungaphumeleli kokuthwala okubeka uxinzelelo olongezelelweyo kwitywina ngokwalo.Isisombululo kukubuyisela impompo yamanzi.
2.Ukuthwala umba
Xa impompo iba nengxolo kwaye kunzima ukuyijika.Oko bekuya kuba kukuguga.Ukujonga oku, unokutsala ibhanti kwi-injini, ujike i-pulley ngesandla, kwaye kufuneka ijike ngokulula nangokutyibilikayo.Ukuba unengxolo engxolayo evela kwimpompo yamanzi, loo nto inokuba ngumba okhoyo.Isisombululo apha, ukubuyisela impompo yamanzi.
3.Impeller umba
Ekugqibeleni, i-impeller inokusilela.Ewe, le yinto ekhohlisayo kuba ngaphandle akukho nto iphosakeleyo kwimpompo yamanzi.Kodwa iiblades ziyakwazi ukuqhawula i-impeller ukuba yiplastiki, okanye ngale nto iyintsimbi nto leyo ethetha ukuba iiblade zinokugqwala kwaye sishiyeke singena blades konke konke.
Olunye uphawu lwe-impeller engaphumeleliyo kukuba i-injini ishushu ngokugqithiseleyo, kodwa awufumani bushushu ngokuvuthela.Ungajonga i-impeller engaphumelelanga ngokunyusa i-injini ukuya kwiqondo lobushushu, ukuze i-thermostat ivuleke, ucime i-injini kwaye emva koko ube nomntu oqalisa i-injini ngelixa ucudisa umbhobho weradiyetha ephezulu.Kwaye kufuneka uve ukuba isipholileyo siqalisa kwangoko ukutyhutyha.Ukuba awuziva njalo, krokrela i-impeller.Ukuba i-impeller itshatyalalisiwe, cinga ukuba yintoni isisombululo?Tshintsha impompo yamanzi.
Enkosi guys ngokukhapha.Siye sathetha ngempompo yamanzi enjini.Sijonge phambili ukwabelana nawe ngakumbi malunga neendawo zemoto nawe.Mandikubobe kwixesha elizayo.
