Isibandisi lokushisa gauge: indawo, ukuhlolwa, esikhundleni

Izinto zesimanje imoto injini esebenza ku imiyalo olulodwa electronic control unit. Lesi sikhungo umyalo ulungisa nemingcele ngazinye ngesisekelo Imininingwane ivela izinzwa ezihlukahlukene. Omunye izakhi letsintsa ngco ukusebenza injini, inzwa kuyinto lokushisa pointer kokupholisayo. Unqoba futhi adlulisele izimpawu okweqile, ukuze kukhompyutha kabusha yangaphakathi omlilo engine.

Uyini inzwa kokupholisayo lokushisa

Isici yisikhungo esisodwa ne izindlu kuchungechunge, okuyinto screwed kwinjini (ngezinye izikhathi - thermostat noma kurediyetha) futhi ukuxhumana ngqo injini kokupholisayo. Ngesikhathi kokuhlinzwa, injini nendlu yaqala ukufudumala, futhi emelana nokubanda enhlanzini yasezindaweni, ngokulandelana, ayaphola. Afundwa ngemigudu ekhethekile block isilinda, uketshezi uyabaselwa, nale ukushisa e kurediyetha. Inzwa kuthola ubukhulu bale amanzi lwaluyophola. Lolu lwazi kufakwa i-computer ngendlela Ukushisa ongaqondile motor. Ukuze uthole ukwaziswa ngokuphathelene nendlela lokushisa esetshenziswa ukulungisa uhlelo yangaphakathi omlilo control injini. Kufanele kuqondwe ukuthi lokhu inzwa akuhambisani ngqo nezinga lokushisa elizosetshenziswa kule metal injini (kuba okuningi), kanye nezinga amalahle ketshezi therethrough olandelanayo.

Kanjani uhlelo impendulo

Injini Ukuphathwa uhlelo - Uhlelo nezimo self-yokufunda, esiyingxenye kwemigomo yangaphakathi omlilo injini enamandla, okungukuthi, esekelwe ukufundwa izinzwa ngesikhathi sangempela ... Ngokuphathelene uhlelo motor kwenza iziphetho mayelana nokuthi iyunithi is sekuqala ukufudumala noma, Ngakolunye uhlangothi, izinga lokushisa namanje eyanele esiphezulu amandla imodi.

Yini umsebenzi inzwa

• I lokushisa kokupholisayo - ingenye izici ezithinta ukulungiswa yenjini. Ngenxa zimpawu kusuka lesi sici sishintsha amapharamitha alandelayo:
• I kwandzisa ingxube nophethiloli. Nxa isitshengiselo inzwa kuyinto ongaphakeme lokushisa kokupholisayo ke isofthiwe sinquma inani amafutha Imibhobho esemzimbeni phezulu. A injini abandayo siphela esigculisayo kokungenzi lutho okusezingeni eliphezulu.
• Ignition isikhathi. ECU sinquma ethuthuka engela esekelwe zamanje injini umthwalo nokuthi leso senzo senziwe bafudumale. abandayo injini pops On buzoba buncane. ukusebenza engafanele inzwa ngeke kuthinte lokhu ipharamitha. Lokhu, kuzoholela ukusebenza engazinzile we motor kuzo zonke izindlela, ukunciphisa amandla ukwandisa petrol.
• Imisebenzi ukupholisa fan. ukusebenza okuphezulu ketshezi lokushisa (emelana nokubanda enhlanzini yasezindaweni) umyalo ukushintshela fan ohlabayo ezipholile. Uma ukusebenza ukufundwa ayilungile isici kuyoba ayilungile. Lapho okweqile fan akumele ukuba azibandakanye kusukela, ngokuvumelana inzwa, ukushisa encane. Futhi igcwele nemiphumela emibi ngendlela efanayo kuze kube ukusonteka ikhanda isilinda.

Uphi isici

Thola lapho inzwa kokupholisayo lokushisa oluphakeme elula. Elementi isethwe ezindaweni ezimbili - block injini noma kwi-thermostat izindlu. Kuzo zombili lezi zimo, uma kuba ukwaziswa okunokwethenjelwa mayelana Ukushisa motor. Ngokwesibonelo, Isibandisi lokushisa inzwa "Reno Logan" noma "Renault Sandero" itholakala eduze kokuphela lokuqala uMbhalo e block isilinda. Lo msuka ezimbili. Yena inika isignali kuya inkomba ku iphaneli sensimbi futhi uhlelo lwe-computer. Uma ngabe le inzwa lokushisa "Opel" Isibandisi, kulezi izimoto, ilungu igibele ngaphakathi ethangini kurediyetha main. On the V emise omlilo yangaphakathi injini izinzwa ezimbili. Beka esinye phezu yasebhange amasilinda ngamunye. Ngezinye izikhathi iinthombe heatsink fan isebenzisa inzwa yesibili efanayo. It wenza umsebenzi owodwa - ulungisa fan ivuliwe.

zinhlobo

Isibandisi lokushisa inzwa kuyinto pointer thermistor. It sishintsha ukumelana layo kuncike Ukushisa ketshezi ngawo kuziwa mbeni. Isebenzisa izinto ezinciphisa ukumelana layo ngokwandisa bafudumale. Ngo kwamanye amadivaysi, asetshenziselwa izakhi, isekelwe ezimisweni ezahlukene, kodwa ezimotweni thermistors zinjalo elula kunazo ngokomlando. Inani lokushisa inzwa lwaluyophola uketshezi kuyahlukahluka, kuye ngezici ebangeni imoto. Ngokwesilinganiso kuba ruble 400-500.

ukusebenza ukuhlola

Ngezinye izikhathi kuyenzeka ukuthi ukuskena iyunithi iqala yokugcizelela ngokucacile noma understate ubufakazi. Ngaphambi hlola kokupholisayo lokushisa inzwa, qiniseka ukuthi ncamashi ke icala ngalezo zinkinga. Ngenxa yale njongo kubalulekile njalo eceleni zonke ezinye izimbangela. Lena ngokuyinhloko inkinga nge wiring. Futhi, sebuningini injini iyazifudumeza ukusebenza kubangela izinkinga thermostat futhi ukubukeka emoyeni emaphaketheni ku ODS. Kumele kukhunjulwe ukuthi ukusebenza umcibisholo noma inkomba ku iphaneli sensimbi kukhona kuphela ua umshayeli esimweni ngoba ECU ukufundwa ngokuvamile uyawasebenzisa ngokuqondile kudivayisi wokulinganisa.

Impilo lokuqinisekisa Izindlela

Ngakho, indlela ukuhlola inzwa kokupholisayo lokushisa? Njengoba thermistor, khona-ke ukuthi unesifo ohmmeter (multimeter kwimodi ohmmeter). Ukuze inzwa ngamunye (noma uhlobo) ikhona ukumelana kuqhathaniswa lokushisa. Ukuxhumanisa multimeter, ukumelana likalwa ezingeni degrees 20, futhi isici ke ngihlaliswa le beaker ngamanzi abilayo. Ukumelana usakujabulela kakhulu, ngokusho etafuleni lapho izindinganiso kucacisiwe tolerances. Uma beya ngaphesheya, inzwa idinga ukushintshwa. Futhi kuwufanele ngibheka out isici short circuit. Uma noma iyiphi into kusobala langakufanelekela ukusebenza.

Njengoba ezothatha isikhundla i-elementi ngezandla zabo

Isibandisi lokushisa gauge ekushintsheni ngokwanele nje. Naphezu kweqiniso lokuthi ku injini ngamunye indawo yayo ihlukile kwalokho, isimiso esejwayelekile uyefana. Yomiselela isici kungcono ukwenza izandla zakho phezu injini abandayo. Nqamula izintambo ukuthi ukusonta uyasikrufulula inzwa. I element omusha kuyadingeka zihlale ziqaphile ukuze singathwesi uphuthelwe eziningi emelana nokubanda enhlanzini yasezindaweni aphume umgodi.

Phawula ukuthi ingxenye threaded i O-metal noma zethusi indandatho okuyinto kuyinto efiselekayo futhi esikhundleni. It ufika uphelele inzwa. Ngemva kokususa inzwa elidala screwed endaweni yawo entsha, pre ezinamafutha akahle egqoke iringi sealant futhi ingxenye threaded. Yingakho motor ngesikhathi umsebenzi kufanele kube abandayo. I emelana nokubanda enhlanzini yasezindaweni evuthayo Shisa ngaphezulu amanzi abilayo. Ungabese ukubeka block endaweni bese egcwele emelana nokubanda enhlanzini yasezindaweni aphuthelwe.

yi

Njengoba kuboniswe, Isibandisi lokushisa gauge inzwa elula, kodwa ibaluleke kakhulu izingxenye elawula uhlelo. On incike ekusebenzeni okuqhubekayo onokwethenjelwa injini.
