Inzwa yokupholisa yabalandeli

Izimoto eziningi zesimanje zifakwe isiphephetha-moya esisebenza ngogesi, esithathe indawo yama-couplings e-viscous angasebenzi kahle. Inzwa ye-fan (inzwa yokushisa yokuvuselela abalandeli) inesibopho sokuvula isiphepho, kanye nokushintsha isivinini).

Ngokuvamile, izinzwa zokupholisa zokwenza kusebenze abalandeli:

• okuthembekile ngokwanele;
• lawula ngempumelelo fan;
• Izinzwa zabalandeli kulula ukuzishintsha;

Ngesikhathi esifanayo, kubalulekile ukulungisa ukungasebenzi kahle okuncane kwalesi sisetshenziswa sokulawula, ngoba ukungasebenzi kahle kwefeni yokupholisa kungaholela ekushiseni ngokweqile kwenjini. Udinga futhi ukwazi ukuthi ungayihlola futhi uyishintshe kanjani inzwa yokushintsha abalandeli. Funda okwengeziwe esihlokweni sethu.

Iphi inzwa yefeni

Inzwa yokuvula/ukuvala ifeni iyisisetshenziswa esisebenza ngogesi sokuvula nokulawula ukusebenza kwefeni epholisayo kagesi. Inzwa yenziwe yasebenza ngokusekelwe ezilinganisweni zezinga lokushisa elipholile. Lo msebenzi wereferensi unquma indawo lapho inzwa yokushintsha abalandeli itholakala khona.

Inzwa yokuvula i-radiator fan itholakala ohlangothini lwe-radiator noma engxenyeni yayo engenhla (phakathi noma eceleni). Ngalesi sizathu, le nzwa ivame ukubizwa ngokuthi inzwa ye-heatsink. Ukuze uqonde kahle ukuthi inzwa yokushintsha abalandeli itholakala kuphi, udinga ukufunda ngokuhlukene imanuwali yobuchwepheshe yemoto ethile.

Inzwa kurediyetha ibangelwa izinga lokushisa lesipholile. Uma uketshezi lushisa kuze kufike ku-85-110 degrees Celsius, othintana nabo "bavale" futhi isiphephelo sikagesi sivula, sishaye injini.

Umphumela uba ukuchithwa kokushisa okuphumelelayo. Ngaphezu kwalokho, izinzwa azigcini nje ngokuvula nokuvala i-fan yokupholisa, kodwa futhi zingashintsha isivinini sayo sokujikeleza. Uma ukushisisa kungephezulu, isivinini sizoba siphansi. Emazingeni okushisa aphezulu, ifeni igijima ngesivinini esigcwele.

Izinhlobo zezinzwa zerediyetha

Namuhla ezimotweni ezahlukene ungathola izinhlobo ezilandelayo eziyinhloko zezinzwa:

1. Inzwa kapharafini;
2. I-Bimetallic;
3. Ama-electronics angathintwa.

Uhlobo lokuqala lusekelwe kumthamo we-hermetic ogcwele i-wax noma omunye umzimba onezici ezifanayo (i-coefficient ephezulu yokwandisa). Izixazululo ze-Bimetal zisebenza ngesisekelo sepuleti ye-bimetal, kuyilapho izixazululo ezingezona othintana nazo zine-thermistor.

Izinzwa ezithinta i-Bimetal kanye nopharafini ezivala futhi zivule isekethe yabalandeli kuye ngezinga lokushisa lesipholile. Ngakolunye uhlangothi, inzwa ye-elekthronikhi ayivali isifunda futhi ilinganisa izinga lokushisa kuphela, ngemva kwalokho idlulisela isignali kukhompyutha. Iyunithi yokulawula bese ivula futhi ivale ifeni.

Izinzwa zothintana nazo zingaba isivinini esisodwa (iqembu elilodwa loxhumana nabo) kanye nesivinini esibili (amaqembu amabili othintana naye) lapho ijubane labalandeli lishintsha kuye ngezinga lokushisa.

Isibonelo, inzwa yokuthungela i-VAZ isebenza kumazinga okushisa amathathu: 82 -87 degrees, 87 - 92 degrees kanye nama-92 - 99 degrees. Ngesikhathi esifanayo, izimoto zakwamanye amazwe zinezigaba ezi-4, umkhawulo ongaphezulu usuka ku-104 kuya ku-110 degrees.

Idivayisi yenzwa ye-radiator

Ngokuqondene nedivayisi ngokwayo, ngokwesakhiwo iyibhokisi lethusi elivaliwe noma lethusi elinento ebucayi ngaphakathi. Ngaphandle kukhona intambo, kanye nesixhumi sikagesi. Ikesi lijikijelwa kurediyetha ngendandatho ye-O endaweni yokungenisa uketshezi olushisayo (eduze nozzle weyunithi yamandla).

Inzwa ixhumene ngqo nesipholile. Amanye amasistimu anezinzwa ezimbili ngesikhathi esisodwa (esikhaleni serediyetha kanye ne-outlet) ukuze uthole isilawuli sokupholisa esinembe kakhudlwana nesivumelana nezimo.

Izinzwa zinentambo engu-M22x1,5, kanye ne-hexagon engu-29 mm. Ngesikhathi esifanayo, kukhona ezinye izinketho lapho intambo incane, M14 noma M16. Ngokuqondene nesixhumi sikagesi, lesi sixhumi sitholakala ngemuva kwenzwa, kodwa kunezinzwa lapho isixhumi sitholakala ngokuhlukile kukhebula.

Indlela yokuhlola inzwa ye-fan bese uyishintsha

Uma i-fan ingavuli ngesikhathi noma injini ihlale ishisa kakhulu, kuyadingeka ukuhlola inzwa ye-radiator. Izinzwa zokuxhumana zingahlolwa ngezandla zakho egaraji elivamile.

Sicela uqaphele ukuthi into yokuqala okufanele uyihlole akuyona inzwa ngokwayo, kodwa i-relay fan yokupholisa kanye ne-wiring. Ukuze wenze lokhu, uzodinga ukunqamula izintambo zenzwa futhi uzifinyeze. Uma kunezintambo ezi-3, sivala phakathi futhi sigcine ngokushintshana. Ngokuvamile, ifeni kufanele ivule kokubili ngesivinini esiphansi nesiphezulu. Uma ikhanyisa, izintambo kanye ne-relay kujwayelekile futhi udinga ukuhlola inzwa.

Ukuze uhlole, thatha isitsha sokupholisa, isihluthulelo sokususa inzwa kanye ne-thermometer, futhi uzodinga i-multimeter, ibhodwe lamanzi nesitofu.

1. Okulandelayo, ukuphela kwebhethri kuyasuswa, ipulaki ye-radiator drain is unscrew futhi uketshezi luyakhishwa;
2. Ngemuva kokukhipha uketshezi, ipulaki ihlehliswa emuva, izintambo zezinzwa ziyasuswa, emva kwalokho inzwa kufanele ikhishwe ngesihluthulelo;
3. Manje amanzi athululelwa epanini ukuze amboze inzwa, ngemva kwalokho i-pan ibekwe esitofu futhi amanzi ayafudumala;
4. Izinga lokushisa lamanzi lilawulwa i-thermometer;
5. Ngokuhambisanayo, udinga ukuxhuma oxhumana nabo be-multimeter kanye nenzwa bese uhlola "isifunda esifushane" emazingeni okushisa ahlukene;
6. Uma abathintwayo bengavali noma kuphawulwe ukungasebenzi kahle, inzwa inephutha futhi idinga ukushintshwa.

Ngokuqondene nokushintsha inzwa yabalandeli, yonke inqubo yehlela ekukhululeni inzwa endala futhi kufakwe isikulufu kwentsha. Kubalulekile futhi ukufaka esikhundleni se-gasket (O-ring).

Okulandelayo, udinga ukuhlola izinga le-antifreeze, engeza uketshezi uma kunesidingo futhi uhlole ukusebenza kwesistimu (fudumeza injini bese ulinda ukuthi fan ivule).

Izincomo

1. Kubalulekile ukuqonda ukuthi inzwa ye-fan iyingxenye encane kodwa ebaluleke kakhulu yesistimu yokupholisa. Kulokhu, inzwa eshiwo iyahluka kunenzwa evamile yokushisa epholile. Uma inzwa yerediyetha yehluleka, umphumela ungaba ukushisisa okubalulekile kwenjini noma umonakalo omkhulu ohlelweni lokupholisa. Ngalesi sizathu, kubalulekile ukuqapha ukunemba nokusebenza kahle kwefeni. Ngokuqondene nokushintshwa kwenzwa ye-radiator, ungafaka kokubili okwangempela nokushintshwa kanye nama-analogues. Into esemqoka okufanele icatshangelwe lapho ukhetha ukuthi inzwa entsha kufanele ibe nezigaba zokushisa ezifanayo ncamashi zokuvula nokuvala ifeni, ezifanele uhlobo lwe-voltage nesixhumi.
2. Futhi qaphela ukuthi ukushisa ngokweqile kwemoto akuhlali kuhlobene nenzwa yabalandeli. Isistimu yokupholisa ukushisa ngokweqile idinga ukuxilonga okuningiliziwe (ukuhlola izinga kanye nekhwalithi ye-antifreeze, ukuhlola ukuqina, ukususa ithuba lokukhipha umoya, njll.).
3. Kuyenzeka futhi ukuthi i-fan motor ihluleke noma ama-fan blades aphule. Kulesi simo, zonke izakhi ezingalungile kufanele zishintshwe, futhi inzwa ku-radiator ayidingi ukushintshwa. Indlela eyodwa noma enye, esimweni ngasinye esithile, ukuhlolwa kochwepheshe kuyadingeka, ngemva kwalokho izinkinga ngesistimu yokupholisa injini ziqedwa ngendlela ehlanganisiwe.
