Isiseko se-thermostat yemoto
Umonakalo kwi-thermostat yemoto unokukhokelela kubushushu obungalawulekiyo benjini, obubonakala ngokugqithisela kakhulu injini okanye ukungaphumeleli ukufikelela kubushushu obuqhelekileyo bokusebenza. Oku, ke ngoko, kubangela uthotho lweengxaki zokusebenza kunye nokuqina.
Impembelelo ephambili kunye neempawu ezithile
Umonakalo we-thermostat ungahlulwahlulwa ube ziimeko ezimbini: ukunamathela kwindawo evulekileyo okanye ukunamathela kwindawo evaliweyo. Ezi meko zimbini zineziphumo ezahluke ngokupheleleyo kwisithuthi.
I-thermostat ivuliwe (injini ayikwazi ukufudumala)
Ukusetyenziswa kwepetroli kunyuka kakhulu: Injini isebenza kubushushu obuphantsi ixesha elide, kwaye ipetroli ayifakwanga kakuhle kwi-atom. Ikhompyutha iya kunyusa umthamo wokufakwa kwepetroli ukuze iqhubeke isebenza, kwaye ukusetyenziswa kwepetroli kunokunyuka nge-10%-15%.
Ukusilela komoya oshushu okanye isiphumo esibi kakhulu: Ubushushu buhlala bulahleka kumjikelezo omkhulu we-coolant, nto leyo ebangela ubushushu bomoya obuphantsi obuvela kwinkqubo yokufudumeza, nto leyo echaphazela kakhulu intuthuzelo yokuqhuba nokukhwela ebusika.
Ukwanda kokuguguleka kwenjini kunye namandla anciphileyo: Kumaqondo obushushu aphantsi, ioyile yenjini ine-viscosity ephezulu, kwaye isiphumo sokuthambisa siyancitshiswa. Ukumelana nokungqubana kwamalungu angaphakathi kuyanda, okukhawulezisa ukuguguleka kwaye kubangele ukungasebenzi kakuhle kwamandla. Kwangaxeshanye, ukusebenza okuphantsi kokutsha kwenza amandla abe buthathaka ngokuthe ngqo.
I-thermostat ivaliwe (injini ishushu kakhulu)
Umngcipheko omkhulu wokonakala kwenjini: I-coolant ayinakungena kwi-circulation enkulu ukuze ichithe ubushushu, kwaye ubushushu buyaqokelelana, nto leyo enokubangela ukuba injini "ibile" (i-coolant ibile) kwaye ikhokelele ekonakaleni kwe-gasket yesilinda, ukutsalwa kwepiston, kwanokungaphumeleli kwenjini.
Ukulahleka kombane kunye nokukhupha umbane: Ubushushu obugqithisileyo bunokubangela ukusebenza okungaqhelekanga kwezinto ezifana neevalvu, ukunciphisa ukuphuma kombane; kwangaxeshanye, ubushushu obuphezulu bunokubangela ukuba izixhobo zokulawula ukukhupha umbane ezifana nesiguquli se-catalytic esineendlela ezintathu zingasebenzi, nto leyo ekhokelela ekukhutshweni komoya ongcolileyo kakhulu.
Umonakalo wetsheyini yenkqubo ohambelanayo: Ubushushu obuphezulu obuqhubekayo buyonakalisa inkqubo yepetroli, inkqubo yokuthambisa, njl.njl., okwandisa kakhulu iindleko zokugcina kunye nobunzima.
Iindlela zokuchonga iimpazamo
Ukongeza ekujongeni ukufundwa okungaqhelekanga kwigeyiji yobushushu bamanzi (ubushushu obuphantsi bexesha elide okanye ukunyuka ngokukhawuleza ukuya kumgca obomvu), ezi ndlela zilandelayo zingasetyenziselwa ukufumanisa kwangaphambili:
Cinezela umahluko wobushushu bemibhobho yamanzi yeradiator: emva kwemizuzu emi-3-5 injini iqalile ukusebenza, chukumisa imibhobho yamanzi ephezulu nesezantsi yeradiator. Kwiimeko eziqhelekileyo, umbhobho ophezulu ushushu kuqala, kwaye umbhobho osezantsi ushushu kamva. Ukuba amaqondo obushushu eemibhobho zombini ahlala efana okanye umahluko wobushushu mkhulu kakhulu (ngaphezu kwe-15℃), i-thermostat inokuba nempazamo.
Nika ingqalelo kutshintsho kumoya oshushu kunye nokusetyenziswa kwepetroli: Ukuba umoya oshushu awufudumali ixesha elide ebusika, okanye ukuba ukusetyenziswa kwepetroli kunyuke ngequbuliso nge-5%-10% kutshanje, kuhamba nokungasebenzi okungazinziyo, ezi zingasetyenziswa njengezikhokelo zokuncedisa ukugweba.
Mamela izandi ezingaqhelekanga: Kunokubakho isandi "esirhawuzelayo" okanye isandi sokungqubana kwesinyithi xa i-coolant ijikeleza.
Iingcebiso zokulungisa nokulungisa
Impembelelo yokusilela kwe-thermostat iyaqhubeka kwaye inxulumene, ukusuka ekuwohlokeni kokusebenza ukuya kumonakalo wecandelo eliphambili. Ke ngoko:
Ukuhlolwa nokutshintshwa ngexesha elifanelekileyo: Nje ukuba ezi mpawu zingasentla zifunyanwe, kufuneka kuhlolwe ngokukhawuleza. Iindleko zokutshintsha i-thermostat ngokwayo azidli ngokuba phezulu, kodwa ukulibazisa ukulungiswa kunokukhokelela ekulungisweni okukhulu kwenjini, ngexabiso elikhulu.
Yenza uhlolo lokuthintela: Kucetyiswa ukuba kwenziwe uhlolo olukhethekileyo lwenkqubo yokupholisa kunye ne-thermostat xa imoto ihambe iikhilomitha ezi-8-100,000 ukuthintela iingxaki ngaphambi kokuba zenzeke.
Musa ukuyisusa ngokwakho: Ukususa i-thermostat kuya kubangela ukuba ubushushu benjini buphele (bulahlekelwe lulawulo), kunye nokufudumeza kancinci xa kuqala kubanda kwaye kube lula ukutshisa xa kushushu kakhulu, oku kuya kwenza kube nzima kakhulu ukusetyenziswa kwepetroli, ukulahleka kwamandla kunye nokuguguleka kwenjini, kwaye kunciphise kakhulu ubomi benjini. Xa ubushushu bunyuka (ubushushu bamanzi bungaphezulu kwama-85℃): I-wax engaphakathi kwe-thermostat core iyanyibilika ngenxa yobushushu, nto leyo ebangela ukwanda okukhulu komthamo. Oku kutyhala ityhubhu yerabha kunye nentonga yokutyhala, koyise amandla entwasahlobo, kwaye kuvula kancinci ivalvu ekhokelela kwi-radiator. I-coolant emva koko iqala ukuhamba nge-radiator ukuze "ijikeleze kakhulu", ithintele injini ekubeni ishushu kakhulu.
Kumaqondo obushushu aqhelekileyo okusebenza (85–95℃): I-thermostat core ilungisa ngokuzenzekelayo ukuvuleka kwevalvu ngokusekelwe kubushushu bamanzi bexesha langempela, ifezekisa ibhalansi eguquguqukayo phakathi kokujikeleza okukhulu nokuncinci, kwaye igcina ubushushu benjini buzinzile.
Isiseko se-thermostat sidla ngokuba sesohlobo "lwe-wax", apho i-wax igcwele ngaphakathi equlethe umgubo we-copper. Umgubo we-copper unokuhambisa ubushushu ngokukhawuleza, uphucule isantya sokuphendula kokuva ubushushu. Imeko yokusebenza kwayo imisela ngokuthe ngqo ukusebenza kakuhle kolawulo lobushushu benjini. Ukuba kukho iimpazamo "ezihlala zivuliwe" okanye "ezihlala zivaliwe", zinokukhokelela ekufudumaleni kancinci, umoya ofudumeleyo onganeleyo, ukusetyenziswa kwepetroli okwandisiweyo, okanye ukugqithisa kakhulu kwenjini, njl.njl., eziziingxaki ezinkulu.
