Yintoni i-thermostat yemoto
Iithermostat zemoto zidlala indima ebalulekileyo kwinkqubo yokupholisa yemoto. Ngokulawula ngobuchule indlela yokuhamba kwe-coolant, kuqinisekisa ukuba injini ihlala isebenza kuluhlu lobushushu olufanelekileyo. I-thermostat yivalvu elawula ukuhamba kwe-coolant. Icandelo layo eliphambili liyinto ebuthathaka kubushushu, efana nevalvu elawula ngokuzenzekelayo kwimoto.
Iindidi kunye nemisebenzi
Kukho iintlobo ezininzi zee-thermostat, kuquka ii-bellows, ii-bimetal sheets, kunye nee-thermostat ze-thermistor. I-thermostat ye-bellows iyaziva utshintsho lobushushu nge-sensor yobushushu kunye nesakhiwo se-bellows, i-bimetal sheet thermostat ilawula ukuvulwa nokuvalwa koqhagamshelwano ngokuguqulwa kwe-bimetal sheet, kwaye i-thermistor thermostat ilawula ukuvulwa kwesekethe ye-compressor ngokutshintsha kwexabiso lokuxhathisa .
Indawo yokufakela kunye nomsebenzi
I-thermostat idla ngokufakwa kumjelo wamanzi wenkqubo yokupholisa kwaye ilawula ubungakanani kunye nokujikeleza kwe-coolant. Umjikelo we-coolant wahlulwe waba yimijikelo emincinci kunye nemijikelo emikhulu, kwaye i-thermostat ilawula ubushushu benjini ngokulawula indlela yokuhamba kwe-coolant. Xa i-thermostat icinyiwe, i-coolant inokugeleza kuphela kwimijikelo emincinci, kwaye xa i-thermostat ivuliwe, i-coolant inokujikeleziswa kwimijikelo emikhulu .
Iimpawu zempazamo kunye neendlela zokufumanisa
Ukusilela kwe-thermostat kudla ngokubonakala kwiimeko ezintathu: ukucima ngokupheleleyo, ukuvulwa ngokupheleleyo, kunye nokunamathela. Ukuvalwa ngokupheleleyo kuya kubangela ukuba injini ifudumale kakhulu, ukuvulwa ngokupheleleyo kuya kubangela ukuba ubushushu benjini bube phantsi kakhulu, kwaye ukunamathela kuya kubangela ukuba ubushushu bungazinzi. Ukujonga ukuba i-thermostat isebenza kakuhle na, unokugweba ngokuchukumisa utshintsho lobushushu lwemibhobho yamanzi ephezulu nesezantsi .
Umsebenzi ophambili we-thermostat yemoto kukulungisa indlela yokuhamba kwe-coolant ukuqinisekisa ukuba injini inokususa ubushushu ngokufanelekileyo phantsi kweemeko ezahlukeneyo zokusebenza. Ngokukodwa, ngokulawula indlela yokuhambahamba kwe-coolant, i-thermostat ivumela injini ukuba ifudumale ngokukhawuleza ngexesha lokuqala okubandayo kwaye igcine ubushushu obufanelekileyo bokusebenza ngexesha lokusebenza okuzinzileyo.
Umgaqo wokusebenza
Ngaphakathi kwi-thermostat kukho into ethintela ubushushu, idla ngokuba yiparafini. Xa injini iqala, ubushushu be-coolant buphantsi, iparafini ihlala iqinile, kwaye i-thermostat ivala umjelo wokuhamba kwe-coolant kwi-radiator, ivumela i-coolant ukuba ingene ngqo kwi-injini block okanye kwi-cylinder head water jacket ngepompo, ngaloo ndlela inyusa ubushushu benjini ngokukhawuleza. Xa ubushushu bamanzi bufikelela kubushushu obuthile (ngesiqhelo malunga nama-85 degrees), iparafini iqala ukunyibilika, i-thermostat ivuleka kancinci, kwaye i-coolant iqala ukujikeleza ngokubanzi kwi-radiator ukuze ikhuphe ubushushu, ngaloo ndlela ilawula ubunzulu bokupholisa kwaye iqinisekise ukuba injini ihlala isebenza kuluhlu lobushushu olufanelekileyo .
Isiphumo sempazamo
Ukuba i-thermostat ayisebenzi kakuhle, njengokungavulwa okanye ukungacimi kakuhle, inokubangela ezi ngxaki zilandelayo:
Ukutshisa kakhulu kwenjini: Ukuba i-thermostat ayivuli kakuhle kwaye i-coolant ayidluli kwi-radiator ukuze ikhuphe ubushushu, injini isenokutshisa kakhulu, nto leyo enokubangela ukusebenza okuphantsi okanye umonakalo.
Ingxaki yokuqalisa ukubanda: ukuba i-thermostat ivuliwe kwangethuba kakhulu, i-coolant ingena kumjikelo omkhulu kwangethuba kakhulu, inokukhokelela kwixesha elide lokufudumeza injini, ubushushu obuphantsi, okuchaphazela ukusebenza kunye noqoqosho lwepetroli.
Ingcebiso yolondolozo
Ukuqinisekisa ukusebenza kwenjini ngendlela eqhelekileyo, kuyacetyiswa ukuba ujonge kwaye ugcine imeko yokusebenza ye-thermostat rhoqo. Ukuba i-thermostat ifunyenwe isebenza kakubi, kufuneka itshintshwe kwangethuba ukuze kuthintelwe iziphumo ezimbi ekusebenzeni kwenjini kunye nobomi bayo.
