I-thermostat - iimpawu zokungasebenzi kwaye iindlela zokusombulula ingxaki

Nayiphi na injini idinga ukupholisa ngexesha lokusebenza. Ngenxa yale njongo, iyunithi inezithuba ezizodwa, kwaye ngaphandle kunikwe i-thermostat. Yonke inkqubo ixhunyaniswa ngamabhobho ephondo. Ukusasazwa okupholileyo kunikwa ngumpompo wamanzi okhethekileyo. Kubantu kuthiwa yi-pomp. Kodwa kungekhona konke. Ukuze i-motor imfudumise ngokukhawuleza, enye yamanzi iyanqunyulwa "ngokunqunyulwa" kwaye ayijikelezi ixesha elithile. Ukulawula ukuhamba okupholileyo, i-thermostat isetyenziswa. Iimpawu zokungasebenzi kwakhe kunye nesixhobo zikwinqaku lethu.

Isici

Yintoni le nto? I-thermostat yi-valve encinci ejongene nokusebenza kwenkqubo yokupholisa. Isixhobo senza umsebenzi wokuhambisa ngokuzenzekelayo ukuhamba okupholileyo kunye namaqondo ahlukeneyo.

Usebenza njani?

Naliphi na injini, iisetyenzisi ezimbini zisetyenzisiweyo:

• Ncinane.
• Omkhulu.

Kuzo zombini kukho amanzi okupholisa. Nangona kunjalo, emva kokuqala kwenjini, iyakuchukunyiswa kuphela ngumbuthano "omncinci". Ngoko imoto iya kufumana ngokukhawuleza ukushisa kwayo, eyaziwayo, i-80-90 degrees Celsius. Ingqungquthela encinci yintsimbi yokutshisa isitofu kunye nomoto ngokwawo. Isiphaluka sesibini kubandakanya i-radiator ngamacangqa, enendawo enkulu yokupholisa. Le radiator ikhona phambi kwenjini. Ukongezelela, ukungenisa emoyeni kunikezelwa yintengiso ekhethekileyo. Ingaba yi-viscous, okanye i-fan yombane. Kodwa ukusebenza kwezi zinto akuxhomekeke kwi-thermostat (apha iqondo lokushisa okanye ibhanti yokuqhuba i-crankshaft isetyenziswa). Kwenzeka ntoni ngeli xesha kunye ne-thermostat ngokwayo? Xa injini iqalile, le valve ivaliwe. Ngaphakathi kwe-thermostat kukho i-wax-sensitive sensitive. Njengoko iqondo lokushisa lokuphucula likhula, liqala ukwandisa ngokuvakalayo. Ngaloo ndlela, i-wax igxobisa igumbi le-rubber. Ixesha lokugqibela liqala ukukhupha intonga yentsimbi yentsimbi ye-chrome, eyenza i-valve isebenze. Xa iqondo lokushisa lifikelela kuma-degree angama-70-80 (umenzi ngamnye unamanani akhe kuloluhlu), i-thermostat iyavula. Umkhuhlane ujikeleza isangqa esigcwele phezu kwesangqa esikhulu, ungena kwi-radiator. Ngokukhawuleza xa iqondo lokushisa liyehla (umzekelo, xa injini iqhutywe), i-valve ivala phantsi kwezenzo zokubuya kwentwasahlobo. Oku kwenzeka konke ngokuzenzekelayo, ngaphandle kokusetyenziswa kwikhompyutha.

Njengoko ubona, ifowuni inomgaqo olula wokusebenza. Nangona kunjalo, le meko ngamanye amaxesha ihluleka. Iimpawu zokungasebenzi kakuhle kwe-thermostat, kwi "Renault Logan" efakwe, ihlala ihamba kunye nokutshisa. Kodwa malunga nento yonke. Ngoko, ngaphantsi siza kuqwalasela iimpawu eziphambili kunye neempawu zentsholongwane ye-thermostat.

I-Logan 1.6 ine-thermostat yobhedu. Ubomi bentsebenzo yabo bukhulu (iminyaka eyi-10 okanye ngaphezulu). Kodwa ngeentlungu zayo, unganqikazi ukuyifaka.

Indlela yokujonga ukuphazamiseka?

Ekubeni i-valve inoxanduva lokusebenza kwenkqubo yokupholisa, ukusasazwa kwamanzi kumasekethe kuya kuphazamiseka. Ngokuqhelekileyo i-thermostat jams kwindawo evuliwe. Ngenxa yoko, i-antifreeze ayiyi kupholisa ngokupheleleyo nangona ifikelele kwiqondo lokushisa elingama-90. Ngenxa yoko, imoto iya kuphelisa. Njengomthetho, emva koko, i-geometry yentloko yebhloko iphulwa. Lungisa loo ntloko ye-cylinder ayixhomekeke kuyo-kuphela ukutshintshwa. Ngoko ke, ungayihoyi iqondo lokushisa.

Kuthekani ukuba injini ibambe "ukushisa"?

Okokuqala, kuyimfuneko ukufakela injini. Vula ibhonethi uze uvumele imoto ukuba ipholise. Musa ukuliphoyisa ngamandla, ngokuthulula amanzi. Oku kuya kubangela ukutyunjelwa kwibloko okanye kwintloko. Kwakhona, musa ukuvula i-cap tank cap-it can fire. Lindela ide iqhube imoto. Unokufikelela kwindawo yokulungiswa ngedoksi okanye ukukhwela iloli.

I-motor ayikwazi ukufudumala kumaqondo okushisa

Okumangalisa ngokwaneleyo, kodwa ezi ziqhelekileyo iimpawu zokungasebenzi kakuhle kwe-thermostat. "I-Kalina" iphantsi kwesi simo. Ukuba i-valve jams kwindawo evulekile, umbane uhlala ujikeleza kwisangqa esikhulu. Umatshini uza kuthatha ixesha elide ukufudumala.

Ngaphandle kokuhamba, ubushushu be-injini abuyi kudlula i-degrees ezingama-60. Njengoko uyakubona, ukugqithisa akusiyo impawu ebalulekileyo ye-thermostat ukungasebenzi. Iimpawu ze-VAZ zeklasi azifani. I-motor kufuneka isebenze kwimiba yayo. Ngaphandle koko, i-viscosity yeoli iguqulwa, iipropati zefilimu kunye nezikhewu kwiiplavines. Injini ixhomekeke kwimithwalo eyongeziweyo.

Kutheni oku kwenzekayo?

Ziziphi izizathu ukuba i-thermostat iphulwe? Iimpawu zokungaphumeleli zibangelwa ukuphulwa komgangatho wesakhiwo. Ekubeni i-wax ifakwe ngaphakathi emzimbeni, iphuma ize ixube kunye ne-cooling liquid. Ukuphulwa koxinzelelo kubangelwa ngenxa ye-antifreeze ye-quality-effective or substitution substitution. Ngenxa yoko, inkqubo ihamba kwinkqubo yokurhoxiswa. Iibhubhu ngaphakathi kwaye kwakhona i-thermostat iqalisa ukubola. Ngenxa yokuguqulwa, ukunyanzeliswa kwetonga elihambayo landa. Ngenxa yintoni enye into eyenziwa yeso sixhobo nje ngokuba i-thermostat iphazamisekile? Iimpawu zokungasebenzi kakubi kubangelwa rhoqo kunye neenjini ezifudumele. Ukuzisa i-motor ukuya kumaqondo okushisa, akufuneki ukuyigcina "engenzi lutho" imizuzu eyi-10. Abanye abashayeli kwaye bacebisa ukuba baqale ukunyakaza ngaphandle kokufudumala, ngaphandle kokuba i-1-2 yeekhilomitha yokuqala yomgwaqo iya kudlula kwimodi elula (akukho ngaphaya kwamawaka amabini amavili). Ngeli xesha elifutshane, imoto iyakwazi ukufudumala kumaqondo okushisa. Emva kokuba ibhulobho idlulile uphawu lwama-70, ungaqalisa ukusebenza ngokugcwele.

Ungajonga njani ngaphandle kokususa kwinjini?

Naliphi na iimpawu ze-thermostat ukungasebenzi, kunokuhlolisiswa "endaweni" ngaphandle kokukususa kwi-motor. Ngoko, qalisa injini kwaye ulinde de utolo luqala ukuhamba kwisikali (kaninzi luqala kuma-40 degrees). Emva koko, vula i-hood uze uzive amagatsha aphezulu naphantsi kwe-radiator. Ukuba iqela elingaphantsi lafudumala ngokukhawuleza (ngaphambi kokuba utolo luqale ukuhamba), ke i-thermostat igxininiswe kwindawo evulekile. Xa ifowuni ivaliwe ngokusisigxina, uya kubona indlela utolo oluqala ngayo "ukunyuka". Oku kubonisa ukungabikho kokupholisa, apho i-radiator inoxanduva. Kodwa ukufikelela kuyo kwinkqubo, i-alas, ivaliwe. Umbhobho ophantsi wegatya uya kuhlala ubanda ngisho nokuba ubushushu buwela emngceleni wee-90 degrees.

Hlola ngokudibanisa

Ukuba ufuna ukuxilongwa ngokuchanekileyo, susa into ephuma kwimoto uyibeke epanini, elalizaliswe ngamanzi ngaphambili. Olu hlobo luya kufana ne-antifreeze yethu. Ngoko, fakela itanki kwi-gas burner kwaye ubilise amanzi. Sijonge ngenyameko kwi-thermostat. Ngokukhawuleza xa amanzi eqala ukuqhuma, into ekhonzayo iya kuvula i-valve. Uza kubona indlela eya kukhula ngayo ngobukhulu. Ukuba oku akuzange kwenzeke, kwaye amanzi sele esele abilayo, ngoko idivaysi igxininiswe.

Malunga nokulungiswa

I-thermostat yinto engenakuphikiswa. Itshintsha ngokupheleleyo kwi-entsha. Iindleko ze-thermostat aphezulu kakhulu, kwaneemoto zangaphandle. Ixabiso alisoloko lidlula umyinge wama-ruble ayi-800.

Isiphelo

Ngoko, safumanisa ukuba i-thermostat ineempawu zokungasebenzi kakuhle. Ukupheliswa kokukhawuleza kokuphazamiseka kukuqinisekisile ukusebenza kweenjini yakho ixesha elide kunye nengxaki.
