Thermostat ivharuvhu inodzora nzira yekuyerera inotonhorera.Icho chigadziriso chekugadzirisa tembiricha, kazhinji chine chikamu chinonzwa tembiricha, chinobatidza nekudzima kuyerera kwemhepo, gasi kana mvura nekuwedzera kwekupisa kana kutonhora kuderera.
Iyo thermostat inogadzirisa otomatiki huwandu hwemvura inopinda muradiator zvinoenderana nekudziya kwemvura inotonhorera, uye inoshandura kutenderera kwemvura kuti igadzirise kupisa kwekupisa simba reinotonhora system uye ive nechokwadi chekuti injini inoshanda mukati metembiricha yakakodzera.Iyo thermostat inofanirwa kuchengetedzwa mune yakanaka tekinoroji mamiriro, zvikasadaro ichakanganisa zvakanyanya kushanda kwakajairika kweinjini.Kana iyo huru yevhavha ye thermostat yakavhurwa yanonoka, ichaita kuti injini iwedzere kupisa;kana vharafu huru yakavhurwa kare, injini yekudziya-nguva ichawedzerwa uye tembiricha yejinjini ichave yakaderera.
Zvese mune zvese, basa re thermostat ndere kuchengetedza injini kuti isanyanya kutonhora.Semuenzaniso, mushure mekunge injini ichishanda zvakajairika, tembiricha yeinjini inogona kunge yakadzikira kana pasina thermostat paunenge uchityaira munguva yechando.Panguva ino, injini inoda kumbomira kusatenderera kwemvura kuti ive nechokwadi chekuti tembiricha yejinjini haina kuderera.
Mashandiro anoita wax thermostat
Thermostat huru inoshandiswa imhando yewakisi thermostat.Kana tembiricha yekutonhodza yakadzikira pane kukosha kwakatarwa, parafini yakanatswa mumutumbi wekushisa we thermostat yakasimba, uye vharafu ye thermostat yakavharwa pakati peinjini neradiator pasi pechiito chechirimo.Chinotonhodza chinodzoserwa kuinjini kuburikidza nepombi yemvura kuitira kutenderera kudiki muinjini.Kana tembiricha yechinhu chinotonhodza ichisvika pamutengo wakatarwa, parafini inotanga kunyunguduka uye zvishoma nezvishoma ikava mvura, uye vhoriyamu inowedzera uye chubhu yerabha inotsikirirwa kuti itete.Kana chubhu yerabha yadzikira, kusunda kunokwira kunoiswa kutsvimbo yekusundidzira, uye tsvimbo yekusundidzira ine inodzika neshure inorovera pavharuvhu kuti ivhure vharuvhu.Panguva ino, chinotonhodza chinoyerera nepakati peradiyeta nevharuvha ye thermostat, uye chobva chayerera chichidzokera kuinjini kuburikidza nepombi yemvura kutenderera hombe.Mazhinji e thermostats akarongwa mupombi yekubuda kwemvura yemusoro wecylinder.Kubatsira kweizvi ndechokuti chimiro chiri nyore, uye zviri nyore kubvisa mabhubhu emhepo mumhepo inotonhora;iyo yakashata ndeyokuti thermostat inowanzovhurwa uye yakavharwa panguva yekushanda, zvichiita kuti oscillation.
State kutonga
Apo injini inotanga kutonhora, kana pane mvura inotonhorera inoyerera ichibva kune inlet pombi yekamuri yepamusoro yemvura yetangi remvura, zvinoreva kuti valve huru ye thermostat haigoni kuvharwa;kana tembiricha yemvura inotonhorera yeinjini inopfuura 70 ℃, kamuri yepamusoro yemvura yetangi remvura inopinda Kana pasina mvura inotonhorera inoyerera ichibva mupombi yemvura, zvinoreva kuti vharafu huru ye thermostat haigone kuvhurwa kazhinji. uye kugadzirisa kunodiwa panguva ino.Kuongorora kwe thermostat kunogona kuitwa pamotokari sezvinotevera:
Ongororo mushure mekunge injini yatangwa: Vhura chivharo chemvura ye radiator, kana iyo yekutonhora muyero yeradiator iri static, zvinoreva kuti thermostat iri kushanda zvakajairika;kana zvisina kudaro, zvinoreva kuti thermostat haisi kushanda nemazvo.Izvi ndezvokuti kana tembiricha yemvura yakaderera kupfuura 70 ° C, silinda yekuwedzera ye thermostat iri muchibvumirano chechibvumirano uye vharafu huru yakavharwa;apo kutonhora kwemvura kwakakwirira kudarika 80 ° C, silinda yekuwedzera inowedzera, valve huru inovhura zvishoma nezvishoma, uye mvura inotenderera muradiator inotanga kuyerera.Kana tembiricha yemvura ichiratidza pasi pe70 ° C, kana paine mvura inoyerera papombi inopinza yeradiator uye tembiricha yemvura ichidziya, zvinoreva kuti vharafu huru ye thermostat haina kuvharwa zvakasimba, zvichiita kuti mvura inotonhorera itenderere. nguva isati yakwana.
Tarisa mushure mekunge tembiricha yemvura ichikwira: Muchikamu chekutanga chekushanda kwejini, tembiricha yemvura inokwira nekukurumidza;apo tembiricha yekushisa yemvura inoratidza 80, chiyero chekupisa chinononoka, zvichiratidza kuti thermostat inoshanda zvakajairika.Pane zvinopesana, kana kutonhora kwemvura kwave kuchikwira nokukurumidza, apo kudzvinyirira kwemukati kunosvika kune imwe nhanho, mvura inopisa inoputika kamwe kamwe, izvo zvinoreva kuti valve huru yakanamatira uye kamwe kamwe yakavhurwa.
Kana tembiricha yemvura yaratidza 70°C-80°C, vhura chivharo cheradiyeta uye redhiyadhidhiya switch, wonzwa tembiricha yemvura nemaoko.Kana zvose zviri kupisa, zvinoreva kuti thermostat iri kushanda zvakanaka;kana tembiricha yemvura pamvura inopinza yemvura yakadzikira, uye radiator yakazadzwa Kana pasina mvura inoyerera kunze kana kuti mvura shoma inoyerera papombi yemvura inopinza yekamuri, zvinoreva kuti vharafu huru ye thermostat haigone kuvhurwa.
Iyo thermostat yakanamatira kana isina kuvharwa zvakasimba inofanira kubviswa pakuchenesa kana kugadziriswa, uye haifaniri kushandiswa pakarepo.

Zvinoenderana neruzivo, hupenyu hwakachengeteka hwewax thermostat inowanzoita 50,000km, saka inofanirwa kuchinjwa nguva nenguva zvichienderana nehupenyu hwayo hwakachengeteka.
Thermostat nzvimbo
Nzira yekuongorora ye thermostat ndeyekutarisa tembiricha yekuvhura, tembiricha yakavhurika zvizere uye kusimudza vharafu huru ye thermostat mutembiricha inogadziriswa inogadzika tembiricha yekudziya.Kana imwe yadzo isingasviki kukosha kwakatarwa, iyo thermostat inofanira kutsiviwa.Semuenzaniso, kune thermostat yejini yeSantana JV, tembiricha yekuvhura yevharuvhu huru i87 ° C plus kana minus 2 ° C, tembiricha yakazaruka i102 ° C plus kana minus 3 ° C, uye yekusimudza yakavhurika zvizere. i>7mm.
Thermostat kuronga
Kazhinji, iyo inotonhorera yemvura-inotonhorera system inoyerera ichibva mumuviri uye inoyerera ichibva muhumburumbira musoro.Mazhinji thermostats ari mu cylinder head outlet line.Kubatsira kwegadziriro iyi ndeyokuti chimiro chiri nyore, uye zviri nyore kubvisa mabhubhu emhepo mumvura inotonhorera;chakashata ndechekuti oscillation inoitika kana thermostat ichishanda.
Semuenzaniso, kana uchitanga injini inotonhora munguva yechando, iyo thermostat valve yakavharwa nekuda kwekuderera kwekushisa kwekutonhora.Kana chinotonhodza chiri muchikamu chidiki, tembiricha inokwira nekukasika uye thermostat valve inovhurika.Panguva imwecheteyo, iyo inotonhorera-inotonhora mu radiator inoyerera ichipinda mumuviri, kuitira kuti inotonhorera inotonhorera zvakare, uye thermostat valve yakavharwa zvakare.Kana tembiricha yekutonhodza ichikwira zvakare, vharafu ye thermostat inovhura zvakare.Kusvikira tembiricha yezvose zvinotonhorera yagadzikana, iyo thermostat vharafu inodzikama uye haizovhurike nekuvhara kakawanda.Chiitiko chekuti thermostat valve inovhurwazve uye yakavharwa munguva pfupi inonzi thermostat oscillation.Kana ichi chiitiko chikaitika, chichawedzera kushandiswa kwemafuta emotokari.
Iyo thermostat inogonawo kurongeka mupombi yekubuda kwemvura yeradiator.Urongwa uhwu hunogona kuderedza kana kubvisa oscillation phenomenon ye thermostat, uye inogona kunyatso kudzora tembiricha yeinotonhorera, asi chimiro chayo chakaomarara uye mutengo wacho wakakwirisa, uye inonyanya kushandiswa mumotokari dzinoshanda zvakanyanya uye mota dzinowanzo kutyaira kumhanya kukuru munguva yechando.[2]
