Chiwotche cha galimoto.
Zochita za malonda
Thermostat iyenera kusungidwa bwino, apo ayi idzakhudza kwambiri ntchito ya injini. Ngati thermostat itsegulidwa (nayi valavu yayikulu ya thermostat ya knuckle) mochedwa kwambiri kapena ngakhale singatseguke, idzapangitsa injini kutentha kwambiri; Itsegulidwa msanga kwambiri, nthawi yotenthetsera injini imakulitsidwa, kotero kuti kutentha kwa injini kumakhala kochepa kwambiri.
Mfundo yogwirira ntchito
Thermostat (Thermostat) ndi mtundu wa chipangizo chowongolera kutentha chokha, nthawi zambiri chimakhala ndi zinthu zowunikira kutentha, potsegula kapena kukulitsa, zomwe zimazimitsa kuyenda kwa choziziritsira, ndiko kuti, malinga ndi kutentha kwa madzi ozizira, zimasinthira madziwo mu radiator, kusintha kuchuluka kwa kayendedwe ka choziziritsira, kuti zisinthe mphamvu yoziziritsira ya makina oziziritsira.
Chida chotenthetsera chomwe injini imagwiritsa ntchito makamaka ndi thermostat ya sera, yomwe imayendetsedwa ndi sera ya parafini mkati mwa kayendedwe ka coolant kudzera mu mfundo yokulitsa kutentha ndi kuzizira. Pamene kutentha kozizira kuli kotsika kuposa mtengo wotchulidwa, parafini yoyengedwa bwino m'thupi lozindikira kutentha kwa thermostat imakhala yolimba, valavu ya thermostat imatseka njira pakati pa injini ndi radiator pansi pa mphamvu ya kasupe, ndipo chotenthetsera chimabwerera ku injini kudzera pa pampu yamadzi kuti chiziyenda pang'ono mu injini. Kutentha kwa chotenthetsera chikafika pamtengo wotchulidwa, parafini imayamba kusungunuka ndikukhala madzi pang'onopang'ono, voliyumu imawonjezeka ndikukanikiza chubu cha rabara kuti chiziyenda pang'ono, pomwe chubu cha rabara chimachepa, ndodo yopukusa imagwira ntchito pakukweza, ndipo ndodo yopukusa imakhala ndi kutsika kumbuyo pa valavu kuti itsegule valavu. Panthawiyi, chotenthetsera chimayenda kudzera mu radiator ndi valavu ya thermostat, kenako chimabwerera ku injini kudzera pa pampu kuti chiziyenda kwambiri. Thermostat yambiri imayikidwa mu chitoliro chotulutsira mpweya cha cylinder head, chomwe chili ndi ubwino wa kapangidwe kosavuta komanso kutulutsa thovu mosavuta mu dongosolo loziziritsira; Vuto lake ndilakuti thermostat nthawi zambiri imatseguka ndi kutseka ikugwira ntchito, zomwe zimapangitsa kuti pakhale kugwedezeka.
Pamene kutentha kwa injini kuli kotsika (pansi pa 70°C), thermostat imatseka yokha njira yopita ku radiator, ndikutsegula njira yopita ku pampu, madzi ozizira ochokera mu jekete mwachindunji kudzera mu payipi kupita ku pampu, ndipo pampu imalowa mu jekete kuti iyendetsedwe, chifukwa madzi ozizira satha ndi radiator, angapangitse kutentha kwa injini kukwera mofulumira, njira yozungulira iyi imatchedwa small cycle. Pamene kutentha kwa injini kuli kokwera (80°C kapena kuposerapo), thermostat imatseka yokha njira yopita ku pampu, ndikutsegula njira yopita ku radiator, madzi ozizira ochokera mu jekete amaziziritsidwa ndi radiator kenako amatumizidwa ku jekete ndi pampu, zomwe zimapangitsa kuti kuziziritsa kukhale kolimba kuti injini isatenthe kwambiri, njira yozungulira iyi imatchedwa large cycle. Pamene kutentha kwa injini kuli pakati pa 70 ndi 80°C, ma cycle akuluakulu ndi ang'onoang'ono amakhalapo nthawi imodzi, kutanthauza kuti, gawo la madzi ozizira kuti ayendetsedwe kwambiri, pomwe gawo lina la madzi ozizira kuti ayendetsedwe pang'ono.
Ntchito ya thermostat ya galimoto ndikuzimitsa kutentha kwa galimoto kusanafike kutentha kwabwinobwino, ndipo choziziritsira cha injini chimabwezedwa ku injini ndi pampu yamadzi kuti chiziyenda pang'ono mu injini, kuti injini itenthe mofulumira. Kutentha kwabwinobwino kukapitirira, kumatha kutsegulidwa kuti choziziritsira chiziyenda kudzera mu radiator circuit ya thanki yonse kuti kutentha kuchepe mwachangu.
Kuyang'anira zinthu
Moyo wotetezeka wa thermostat ya sera nthawi zambiri umakhala 50,00km, kotero imafunika kuisintha nthawi zonse malinga ndi moyo wake wotetezeka. Onani njira ya thermostat mu thermostat yosinthika kutentha. Yang'anani kutentha kotsegulira kwa valavu yayikulu ya thermostat, kutentha kotseguka kwathunthu ndi kukweza, komwe sikukwaniritsa mtengo wokhazikika, thermostat iyenera kusinthidwa. Mwachitsanzo, thermostat ya injini ya Santana JV, kutentha kotsegulira kwa valavu yayikulu ndi 87 ° C kuphatikiza kapena kuchepera 2 ° C, kutentha kotsegulira kwathunthu ndi 102 ° C kuphatikiza kapena kuchepera 3 ° C, ndipo kukweza kwathunthu kotsegulira ndi > 7mm.
Chochitika cholakwika
Muzochitika zachizolowezi, injini ikayamba, kutentha kwa ntchito kumakhala kochepa kwambiri, kuti kutentha kukwere mofulumira, kenako kudzera mu thermostat control (valavu yayikulu ya thermostat imatsekedwa), kotero kuti choziziritsira kudzera pa pampu yamadzimadzi kulowa mu chitoliro chamadzi, choziziritsira sichimayenda kudzera mu radiator, iyi ndi nthawi yaying'ono, pamene kutentha kwa choziziritsira kumafika madigiri 87 (thermostat ya Bora imatseguka kutentha kwa madigiri 87, Pambuyo pake, valavu ya thermostat imatsegulidwa, choziziritsira chimayamba kuyenda kudzera mu radiator, ndipo makina oziziritsira amalowa mu nthawi yayikulu. Kawirikawiri, pafupifupi mphindi zisanu galimoto itayambika, kutentha kwa choziziritsira kumatha kufika madigiri 85 ~ 105, ngati kutentha kwabwinobwino kwa ntchito sikunafike kwa nthawi yayitali, kapena kutentha kwakwera kuposa madigiri 110, ziyenera kukayikiridwa ngati thermostat ndi yolakwika.
