Thermostat yamagalimoto.
Zochita zamalonda
Thermostat iyenera kukhala yogwira ntchito bwino, apo ayi idzakhudza kwambiri momwe injini ikuyendera. Ngati chotenthetsera chitseguka (pali valavu yayikulu ya knuckle thermostat) mochedwa kwambiri kapena sichingatseguke, izi zimapangitsa injini kutenthedwa; Tsegulani molawirira kwambiri, nthawi yotenthetsera injini imakulitsidwa, kotero kuti kutentha kwa injini kumakhala kotsika kwambiri.
Mfundo yogwira ntchito
Thermostat (Thermostat) ndi mtundu wa chipangizo chowongolera kutentha, nthawi zambiri chimakhala ndi magawo ozindikira kutentha, pakukulitsa kapena kutsika kuti atseguke, kuzimitsa kutulutsa koziziritsa, ndiko kuti, malinga ndi kutentha kwamadzi ozizira amasintha madzi kukhala radiator, kusintha mawonekedwe ozizirira, kusintha kuziziritsa kwadongosolo lozizirira.
Chotenthetsera chomwe chimagwiritsidwa ntchito ndi injini nthawi zambiri chimakhala chotenthetsera sera, chomwe chimayendetsedwa ndi sera ya parafini mkati mwa kuzungulira kwa koziziritsa kukhosi kudzera mu mfundo ya kufutukuka kwa kutentha ndi kufupikitsa kuzizira. Kutentha kozizira kumakhala kotsika kuposa mtengo womwe watchulidwa, parafini woyengedwa mu thupi lozindikira kutentha kwa thermostat imakhala yolimba, valavu ya thermostat imatseka njira pakati pa injini ndi radiator pochita masika, ndipo choziziritsa kukhosi chimabwerera ku injini kudzera pa mpope wamadzi kuti uziyenda pang'ono mu injini. Kutentha kozizirirako kukafika pamtengo womwe watchulidwa, parafini imayamba kusungunuka ndikukhala madzi pang'onopang'ono, voliyumu imawonjezeka ndikukankhira chubu la rabara kuti lichepetse, pomwe chubu cha rabara chimacheperachepera, ndodo yokankhira imagwira ntchito mokweza m'mwamba, ndipo ndodo yokankhira imakhala ndi kutsika kobwerera kumbuyo kwa valavu kuti mutsegule valavu. Panthawiyi, choziziritsa kukhosi chimadutsa mu radiator ndi valavu ya thermostat, kenako chimabwereranso ku injini kudzera pa mpope kuti chiziyenda kwambiri. Ambiri a thermostat anakonza mu yamphamvu mutu kubwereketsa chitoliro, amene ali ndi ubwino dongosolo losavuta ndi kutulutsa mosavuta thovu mu dongosolo yozizira; Choyipa chake ndi chakuti chotenthetseracho nthawi zambiri chimatsegula ndikutseka chikagwira ntchito, zomwe zimapangitsa kuti chizungulire.
Kutentha kwa injini kukatsika (pansi pa 70 ° C), chotenthetsera chimangotseka njira yopita ku rediyeta, ndikutsegula njira yopita ku mpope, madzi ozizira akuyenda kuchokera ku jekete molunjika kudzera papaipi kupita ku mpope, ndi mpope mu jekete kuti ayendetse, chifukwa madzi ozizira samaphwanyidwa ndi radiator, amatha kupangitsa kuti kutentha kwa injini kukwera kumatchedwa njira yaying'ono yozungulira iyi. Kutentha kwa injini kukakwera (80 ° C kapena kupitirira apo), chotenthetsera chimangotseka njira yopita ku mpope, ndikutsegula njira yopita ku rediyeta, madzi ozizira omwe amachokera ku jekete amatsitsidwa ndi radiator kenako amatumizidwa ku jekete ndi mpope, kuwongolera kuzizira kwambiri kuti injini isatenthedwe, njira yozungulira iyi imatchedwa kuzungulira kwakukulu. Pamene kutentha kwa injini kuli pakati pa 70 ndi 80 ° C, maulendo akuluakulu ndi ang'onoang'ono amakhalapo nthawi imodzi, ndiko kuti, gawo la madzi ozizira kuti ayendetse kwambiri, pamene gawo lina la madzi ozizira limazungulira pang'ono.
Ntchito ya thermostat yagalimoto ndikutseka kutentha kwagalimoto kusanafike kutentha kwanthawi zonse, ndipo choziziritsa cha injini chimabwezeredwa ku injini ndi mpope wamadzi kuti upangitse kuzungulira pang'ono mu injini, kuti injiniyo imatha kutentha mwachangu. Kutentha kwabwinoko kukakhala kopitilira, kumatha kutsegulidwa kuti choziziritsa chiziyenda kudzera mugawo la radiator la tanki yonse kuti lizitentha mwachangu.
Kuwunika kwazinthu
Moyo wotetezeka wa wax thermostat nthawi zambiri umakhala 50,00km, motero umafunika kuyisintha pafupipafupi malinga ndi moyo wake wotetezeka. Yang'anani njira ya thermostat mu kutentha chosinthika chotenthetsera zipangizo zotentha fufuzani kutentha kwa kutsegula kwa valavu yaikulu ya thermostat, kutentha kotseguka ndi kukweza, zomwe sizikugwirizana ndi mtengo wokhazikika, thermostat iyenera kusinthidwa. Mwachitsanzo, thermostat ya injini ya Santana JV, kutentha kotsegulira kwa vavu yayikulu ndi 87 ° C kuphatikiza kapena kuchotsera 2 ° C, kutentha kwathunthu ndi 102 ° C kuphatikiza kapena kuchotsera 3 ° C, ndi kukweza kwathunthu ndi> 7mm.
Chochitika cholakwika
Nthawi zonse, injini ikayamba, kutentha kwa ntchito kumakhala kotsika kwambiri, kuti kutentha kukweze msanga, kenako kudzera mu chowongolera cha thermostat (valavu yayikulu ya thermostat yotsekedwa), kotero kuti choziziritsa ndi mpope wamadzimadzi mu chitoliro chamadzi, choziziritsa kuzizira sichimadutsa pa radiator, uku ndikuzungulira pang'ono, kutentha kwa choziziritsa kukufika madigiri 87 (Bora wa thermostat, valavu yotseguka, valavu yotseguka, 87 valavu yotseguka). choziziritsa kukhosi chimayamba kuyenda mu rediyeta, ndipo dongosolo loziziritsa limalowa mkombero waukulu Nthawi zambiri, pafupifupi mphindi zisanu galimoto itayamba, kutentha koziziritsa kumatha kufika madigiri 85 ~ 105, ngati kutentha kwanthawi zonse sikunafike kwa nthawi yayitali, kapena kutentha kwakwera kuposa madigiri 110, ziyenera kuganiziridwa ngati thermostat ndi yotentha.
Chonde tiyimbireni ngati mukufuna such mankhwala.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zolandiridwa kuti mugule.
