Isistimu yokupholisa injini: isimiso sokusebenza kanye nezingxenye eziyinhloko

Injini yemoto yakho isebenza kahle kakhulu emazingeni okushisa aphezulu. Lapho injini ibanda, izingxenye zayo ziguga kalula, kukhishwa ukungcola okwengeziwe, futhi injini iyancipha ukusebenza kahle. Ngakho, omunye umsebenzi obalulekile wesistimu yokupholisa ngu ukufudumala kwenjini okusheshayo bese ugcina izinga lokushisa lenjini elingashintshi. Umsebenzi oyinhloko wesistimu yokupholisa ukugcina izinga lokushisa eliphezulu lokusebenza kwenjini. Uma uhlelo lokupholisa, noma iyiphi ingxenye yalo, luhluleka, injini izoshisa kakhulu, okungaholela ezinkingeni eziningi ezinkulu.

Wake wacabanga ukuthi kuzokwenzekani uma uhlelo lwakho lokupholisa injini lungasebenzi kahle? Ukushisa ngokweqile kungabangela ama-gaskets ekhanda ukuthi aqhume ngisho namabhulokhi amasilinda uma inkinga inkulu ngokwanele. Futhi konke lokhu kushisa kumele kuliwe. Uma ukushisa kungasuswa enjinini, ama-piston ashiselwe ngokoqobo ngaphakathi kwamasilinda. Khona-ke udinga nje ukulahla injini futhi uthenge entsha. Ngakho-ke, kufanele unakekele uhlelo lokupholisa injini futhi uthole ukuthi lusebenza kanjani.

Izingxenye zesistimu yokupholisa

Isipholisanjini

Irediyetha isebenza njengesishintshi sokushisa senjini. Ngokuvamile kwenziwa nge-aluminium futhi inobuningi bamashubhu obubanzi obuncane anezimbambo ezinamathiselwe kuwo. Ngaphezu kwalokho, ishintsha ukushisa kwamanzi ashisayo avela enjini nomoya ozungezile. Iphinde ibe ne-drain plug, i-inlet, ikepisi elivaliwe, kanye ne-outlet.

Iphampu

Njengoba into epholile iphola ngemva kokuba kurediyetha, iphampu yamanzi iqondisa uketshezi emuva kusilinda block , i-heater core kanye nekhanda lesilinda. Ekugcineni, uketshezi luphinde lungene kurediyetha, lapho luphinde luphole khona.

I-Thermostat

Lena i-thermostat, esebenza njengevalvu yesipholile futhi iyivumela kuphela ukuthi idlule kurediyetha lapho izinga lokushisa elithile leqiwe. I-thermostat iqukethe upharafini, owanda ezingeni elithile lokushisa futhi uvule kulelo zinga lokushisa. Isistimu yokupholisa isebenzisa i-thermostat ukuze ukulawulwa kwezinga lokushisa elivamile lokusebenza kwenjini evuthayo yangaphakathi. Lapho injini ifinyelela izinga lokushisa elijwayelekile lokusebenza, i-thermostat iyakhahlela. Khona-ke into epholile ingangena kurediyetha.

Ezinye izingxenye

Amapulagi aqandayo: empeleni, lawa amapulaki ensimbi aklanyelwe ukuvala izimbobo ku-cylinder block kanye namakhanda angama-cylinder akhiwe phakathi nenqubo yokuphonsa. Esimeni sezulu esibandayo, bangaphuma uma kungekho ukuvikelwa kwesithwathwa.

Ikhava ye-Head Gasket/Timing: ivala izingxenye eziyinhloko zenjini. Ivimbela ukuxubana kwamafutha, i-antifreeze kanye ne-cylinder pressure.

Ithangi lokuchichima le-radiator: leli ithangi lepulasitiki elivame ukufakwa eduze kwe-radiator futhi linendawo yokungena exhunywe kurediyetha kanye nembobo eyodwa yokuchichima. Leli ithangi elifanayo oligcwalisa ngamanzi ngaphambi kohambo.

Amapayipi: Uchungechunge lwamapayipi erabha axhuma irediyetha enjinini okugeleza kuyo isipholile. Lawa mapayipi angase aqale ukuvuza ngemva kweminyaka embalwa yokusetshenziswa.

Isebenza kanjani isistimu yokupholisa injini

Ukuze uchaze ukuthi isistimu yokupholisa isebenza kanjani, kufanele uqale uchaze ukuthi yenzani. Kulula kakhulu - isistimu yokupholisa yemoto ipholisa injini. Kodwa ukupholisa le njini kungase kubonakale kuwumsebenzi onzima, ikakhulukazi uma ucabanga ingakanani ukushisa okukhiqizwa yinjini yemoto. Ngiyacabanga ngakho. Injini yemoto encane ehamba ngamamayela angu-50 ngehora emgwaqeni omkhulu ikhiqiza ukuqhuma okungaba ngu-4000 XNUMX ngomzuzu.

Kanye nakho konke ukungqubuzana okuvela ezingxenyeni ezihambayo, lokho kungukushisa okuningi okudingeka kugxiliswe endaweni eyodwa. Ngaphandle kwesistimu yokupholisa esebenza kahle, injini izoshisa ngokweqile futhi iyeke ukusebenza kungakapheli imizuzu. Isistimu yokupholisa yesimanje kufanele gcina imoto ipholile endaweni yokushisa engu-115 degrees futhi kufudumele nasebusika.

Kwenzakalani ngaphakathi? 

Isistimu yokupholisa isebenza ngokudlula njalo into epholisayo kumashaneli akubhulokhi yesilinda. Isipholile, esishayelwa iphampu yamanzi, siphoqelelwa ngebhulokhi yesilinda. Njengoba ikhambi lidlula kula mashaneli, limunca ukushisa kwenjini.

Ngemuva kokuphuma enjinini, lolu ketshezi olushisayo lungena ku-radiator, lupholiswe wukugeleza komoya ongena nge-radiator grille yemoto. Uketshezi luyapholiswa njengoba ludlula kurediyetha , ebuyela enjinini futhi ukuze athathe ukushisa kwenjini okwengeziwe futhi ahambe nakho.

Kukhona i-thermostat phakathi kwe-radiator nenjini. kuncike ezingeni lokushisa I-thermostat ilawula ukuthi kwenzekani oketshezini. Uma izinga lokushisa loketshezi lehla ngaphansi kwezinga elithile, isixazululo sidlula irediyetha futhi esikhundleni salokho siqondiswe emuva esivimbeni senjini. Isipholile sizoqhubeka sijikeleza size sifinyelele izinga elithile lokushisa bese sivula ivalve ku-thermostat, siyivumele ukuba idlule kurediyetha futhi ukuze iphole.

Kubonakala sengathi ngenxa yokushisa okuphezulu kakhulu kwenjini, isipholile singafinyelela kalula endaweni yokubilisa. Nokho, uhlelo lungaphansi kwengcindezi yokuvimbela lokhu ukuthi kungenzeki. Uma isistimu ingaphansi kwengcindezi, kuba nzima kakhulu ukuthi into epholile ifike endaweni yayo yokubila. Nokho, ngezinye izikhathi umfutho uyakhula futhi kufanele wehliswe ngaphambi kokuba ophe umoya epayipini noma ku-gasket. I-cap ye-radiator ikhulula ingcindezi eyengeziwe kanye noketshezi, okuqoqana ku-tank yokwandisa. Ngemva kokupholisa uketshezi ethangini lokugcina izinga lokushisa elamukelekayo, lubuyiselwa ohlelweni lokupholisa ukuze lujikelezwe kabusha.

I-Dolz, ama-thermostats ekhwalithi namaphampu amanzi esistimu yokupholisa enhle

I-Dolz yinkampani yaseYurophu enamathela eqoqweni lezindinganiso zokuqamba izinto ezintsha, ukusebenza kahle, ukwethembeka kanye nokusimama ezisombululweni zayo zokuthola usizo emhlabeni wonke ezisiza abalingani bayo namakhasimende ukuhambisa amaphampu amanzi lapho edingeka khona. Ngaphezu kweminyaka engama-80 yomlando, i-Industrias Dolz injalo umholi womhlaba kumaphampu amanzi anezinhlobonhlobo zemikhiqizo ehlanganisa izinto zokusabalalisa kanye nama-thermostats ukukhiqizwa kwezingxenye ezisele. Uma unentshisekelo ngemikhiqizo yethu, sicela usithinte futhi sizokwazisa.
