Ukuxilongwa kwephutha nokugcinwa kwesistimu yokupholisa injini yemoto (二)
2021-08-11
Iyabila futhi iphenduke ibe evamile kuphela ngemva kokwenza amanzi okupholisa. Ukuhlaziya nokuxilongwa:
(1) Lapho injini ishisa ngokuzumayo phakathi nokushayela, qala ngokunaka isimo esiguquguqukayo se-ammeter. Uma i-ammeter ingabonisi ukushaja lapho inyusa i-throttle, futhi inaliti yegeji ikhishwa kuphela ngo-3 ~ 5A Ukushwibeka ngokuphindaphindiwe emuva ku-"0" isikhundla kubonisa ukuthi ibhande lefeni liphukile. Uma i-ammeter ikhombisa ukushaja, vala injini bese uthinta irediyetha nenjini ngesandla. Uma izinga lokushisa lenjini liphezulu kakhulu futhi izinga lokushisa le-radiator liphansi, libonisa ukuthi i-shaft yepompo yamanzi kanye ne-impeller ikhululekile, iphazamisa ukujikeleza kwamanzi okupholisa; Uma umehluko wezinga lokushisa phakathi kwenjini nerediyetha ungemkhulu, hlola ukuthi akukho yini ukuvuza okukhulu kwamanzi ohlelweni lokupholisa. Ngemva kokutholwa, izinga lokushisa lenjini liphezulu kakhulu futhi izinga lokushisa lerediyetha liphansi kakhulu, futhi iphampu yamanzi inezinkinga;
(2) Izinga lokushisa lamanzi okupholisa likhuphuka ngokushesha ekuqaleni kokuqala, okuholela ekubiliseni kwamanzi okupholisa. Ivalvu eyinhloko ye-thermostat enamasistimu amaningi iyawa futhi ibhajwe ngokuphambana epayipini lokungena amanzi lerediyetha, elithiya ukuhamba okukhulu kwamanzi okupholisa futhi inyuse ngokushesha ukucindezela ohlelweni lokupholisa. Lapho ingcindezi yangaphakathi ifinyelela ezingeni elithile, i-valve eyinhloko ebambekile izoshintsha ngokuzumayo ukushintsha ukuma kwayo futhi ixhume ngokushesha umzila omkhulu wamanzi wokujikeleza, Ngalesi sikhathi, amanzi abilayo asula ngokushesha i-cap ye-radiator. Uma amanzi okupholisa ehlala ebila ngesikhathi sokushayela, misa injini ngokushesha ukuze injini ihambe ngesivinini esiphansi kuze kube yilapho izinga lokushisa lamanzi selivamile, bese uvala ukuze ihlolwe. Akuvunyelwe ukuxuba amanzi ukuze aphole, ukuze kuvinjwe ukuqhekeka kwezingxenye ezifanele ngenxa yengcindezi yangaphakathi ebangelwa umehluko omkhulu kakhulu wokushisa. Uma i-cylinder gasket ishiswa, ngezinye izikhathi umlomo wethangi lamanzi ungachichima futhi ukhiphe ama-bubbles, okubonisa isimo esibilisayo samanzi apholisayo. Lokhu kungenxa yokuthi i-gasket yesilinda ishisiwe noma i-cylinder head kanye ne-cylinder liner zinemifantu, okwenza igesi enomfutho ophezulu igijimele ejazini lamanzi futhi ikhiphe amabhamuza anolaka. Uma ukuqhekeka kwe-cylinder gasket noma ikhanda le-cylinder lixhunywe ne-lubricating oil circuit, ama-oil stains nawo azovela ku-tank yamanzi. Indlela yokuhlola igesi enomfutho ophezulu kumzila wesilinda ohlelweni lokupholisa: khipha ibhande lefeni bese umisa iphampu yamanzi. Lapho isiqalisi sigijima ngaphansi kwesivinini esimaphakathi, amabhamuza azobonakala endaweni yokungena amanzi ethangini lamanzi futhi kuzwakale umsindo othi "grunt, grunt", okuwukuvuza komoya okuncane; Uma ipompo yamanzi ingamiswa, ama-bubbles angabonakala ngokucacile futhi umsindo we "grunt, grunt" ungazwakala, okuwukuvuza komoya okungathi sína; Ikhava yethangi lamanzi izophephuka njengebhodwe elibilayo, okuwukuvuza komoya okubi. Uma amanzi okupholisa amuncwa kusilinda, isitimu sizokhishwa epayipini le-exhaust ngesikhathi sokuqala bese kukhishwa intuthu emhlophe ngesikhathi sokusebenza. Ayikho into enjalo ngemva kokutholwa.

Umphumela wokuhlolwa: kunenkinga ngepompo yamanzi. ukulungisa kabusha:
Ukususwa kwesikali: sebenzisa ukusabela kwekhemikhali phakathi kwezinto ze-asidi noma i-alkali nesikali ukuze ukhiqize izinto ezintsha ezincibilikayo emanzini ukuze ususe isikali. Ngesikhathi sokuhlanza, kungcono ukusebenzisa indlela ye-micro circulation: okokuqala hlanza ngesisombululo esine-acidic, bese ugeza ngesisombululo se-alkali sokungathathi hlangothi. Ngesikhathi sokuhlanza, i-ejenti yokwehlisa ijikeleza ethangini lamanzi ngokucindezela okuthile (ngokuvamile i-0.1MPa) imizuzu emi-5 Ngemva kokuhlanza.
Ukulungiswa kwe-radiator: Ukutholwa kwamaphutha erediyetha ukuvuza. Ngokuvamile kunezindlela ezimbili zokulungisa ukuvuza kwe-radiator; Indlela yokulungisa i-welding kanye nendlela yokuxhuma. Lungisa imoto nge-ejenti yokuxhuma irediyetha (okungukuthi indlela yokuxhuma). Ngaphambi kokukhanda, hlanza irediyetha bese wengeza u-1:2 Injini izosebenza cishe ku-80 ℃ imizuzu emi-5 Ngemva kwalokho, khipha amanzi ane-alkaline, hlambulula ngamanzi ahlanzekile, qalisa injini, bese ukhipha amanzi lapho imoto ishisisa aze afike ku-80. ℃. Bese ususa i-thermostat bese ulungisa i-ejenti yokuxhuma ibe ngu-1:20 Engeza amanzi ngesilinganiso, qala injini, ukhuphule izinga lokushisa lamanzi libe ku-80 ~ 85 ℃ futhi ugcine i-1.0min. Gcina amanzi okupholisa aqukethe i-ejenti yokuxhuma ohlelweni lokupholisa amahora angu-3 ~ 4 O, Nkulunkulu wami. I-radiator elungisiwe iphumelele ukuhlolwa kokuvuza futhi yalethwa ngaphandle kokuvuza.
Ukugcinwa kwepompo lamanzi: ngaphambi kokulungiswa kwepompo yamanzi, susa iphampu yamanzi enjinini bese uyiqaqa. Lapho ukhipha iphampu yamanzi, qala uvule i-switch yokukhipha amanzi ye-radiator kanye nenjini, ufake isipholile esitsheni esihlanzekile, khipha amabhawodi okulungisa epompo yamanzi namabhawodi esihlalweni se-pulley, khipha indawo yokungena amanzi kanye ne-outlet. ipayipi, futhi ukhiphe isiphephetha-moya kanye nezinye izinhlanga ezifanele bese ushayela ama-pulley. Susa induku yokulungisa nebhawodi lebhande lokushayela, bese ususa iphampu yamanzi kanye ne-gasket yokuvala. Lapho uqaqa iphampu yamanzi, qala ngokukhulula amabhawodi ekhava epompo, khipha isembozo sepompo kanye ne-gasket yokuvala. Bese udonsa phansi i-pulley yabalandeli nge-donsa; Bese ufaka umzimba wepompo yamanzi emanzini noma emafutheni bese uwufudumeza ufike ku-75 ~ 85 ℃, susa ukuthwala kwepompo lamanzi, ukuhlanganiswa kophawu lwamanzi kanye nokuhlanganiswa kwepompo yepompo yamanzi ngepompo ephethe i-disassembler bese ucindezela, bese ekugcineni ucindezela umshini wepompo yamanzi. . Izinto zokuhlolwa zezingxenye zephampu yamanzi ikakhulukazi zifaka: (1) ukuthi umzimba wepompo kanye nesihlalo somshini wokudonsa amanzi zigugile futhi zonakele, bese zishintshwa uma kunesidingo (2) Ukuthi i-shaft yepompo igobile, noma ngabe ijenali igugile kakhulu, nokuthi Intambo yokuphela kwe-shaft yonakalisiwe i-seal ne-bakelite pad yeqa umkhawulo wesevisi, izoshintshwa ngezingxenye ezintsha (5) Lapho uhlola ukuguga kwe-shaft, linganisa ukuchezuka ngenkomba yokudayela. Uma idlula u-0.1mm, shintsha i-bearing ufake entsha. Naka amaphuzu alandelayo lapho ulungisa iphampu yamanzi: (1) uma uphawu lwamanzi lugugile futhi lugobile, lungenziwa isicaba ngendwangu ye-emery. Uma igqokwe kakhulu, kufanele ishintshwe; Uma kunemihuzuko eqinile esihlalweni sophawu lwamanzi, singasikwa nge-reamer yendiza noma nge-lathe (2) Ukulungiswa kwe-welding kuvunyelwe uma iphampu inomonakalo olandelayo: ubude buyi-30mm Ngezansi, akukho ukuqhekeka okudlulela umgodi wokuzala; I-flange ehlanganiswe nekhanda le-cylinder yonakalisiwe; Imbobo yesihlalo se-oil seal yonakalisiwe (3) Ukugoba kwe-pump shaft akufanele kudlule u-0.03mm, ngaphandle kwalokho kuzoshintshwa noma kulungiswe ngokucindezela okubandayo (4) Faka esikhundleni se-impeller blade eyonakele. Ukuhlanganisa nokufakwa kwephampu yamanzi.
Ukulandelana kuwukuhlanekezela kokuqaqa nokuqaqa. Ngesikhathi somhlangano, qaphela ukucaciswa kwezobuchwepheshe phakathi kwezingxenye zokukhwelana. Lapho ufaka inhlanganisela yepompo yamanzi enjinini, naka lezi zindaba ezilandelayo: (1) faka i-gasket entsha ngesikhathi sokufakwa (2) Hlola futhi ulungise ukuqina kwebhande. Ngokuvamile, i-100N isetshenziswa phakathi kwebhande Uma ukucindezela kwesokudla kucindezela ibhande, ukuchezuka kuzoba ngu-8 ~ 12mm. Uma ingahlangabezani nezidingo, lungisa ukuqina kwayo (3) Ngemva kokufaka iphampu yamanzi, xhuma amapayipi amanzi athambile esistimu yokupholisa, engeza amanzi okupholisa, qala injini, futhi uhlole ukusebenza kwepompo yamanzi kanye ne- uhlelo lokupholisa lokuvuza.
Ngokulungisa okungenhla, izinga lokushisa lokusebenza kwenjini yemoto libuyela kokujwayelekile.
