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 zigawo zozindikira kutentha, pakukulitsa kapena kutsika kuti mutsegule, kuzimitsa kutuluka kwa choziziritsa kukhosi, ndiko kuti, malinga ndi kutentha kwamadzi ozizira amasintha madzi kukhala rediyeta, sinthani mawonekedwe ozizirira, kuti musinthe kuzizirira kwa makina ozizira.
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 chozizira chimabwerera ku injini kudzera pa mpope wa madzi kuti aziyenda 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 lifooke, pomwe chubu cha rabara chimachepa, ndodo yokankhira imagwira ntchito kumtunda, ndipo ndodo yokankhira. ali ndi valavu yopita pansi kuti atsegule 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), chotenthetseracho chimatseka njira yopita ku radiator, ndikutsegula njira yopita ku mpope, madzi ozizira akuyenda kuchokera ku jekete mwachindunji kudzera pa hose kupita ku mpope, ndi mpope. mu jekete kuti azizungulira, chifukwa madzi ozizira samatayika ndi rediyeta, amatha kupangitsa kutentha kwa injini kukukwera mwachangu, njira yozungulira iyi imatchedwa kazungulira kakang'ono. Kutentha kwa injini kukakwera (80 ° C kapena kupitilira apo), chotenthetsera chimangotseka njira yopita ku mpope, ndikutsegula njira yopita ku radiator, madzi ozizira omwe akuyenda kuchokera ku jekete amazizidwa ndi radiator kenako kutumizidwa. kwa 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.
Udindo wa thermostat yagalimoto ndikutseka kutentha kwagalimoto kusanafike kutentha kwabwinobwino, ndipo choziziritsa cha injini chimabwezeredwa ku injini ndi mpope wamadzi kuti upangitse kuzungulira pang'ono mu injini, kuti injini imatha kutentha kwambiri. 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, ndikukweza kotsegulira kwathunthu. > 7 mm.
Chochitika cholakwika
Muzochitika zachilendo, injini ikayamba, kutentha kwa ntchito kumakhala kochepa kwambiri, kuti kutentha kukweze mofulumira, kenako kupyolera mu ulamuliro wa thermostat (valavu yaikulu ya thermostat yotsekedwa), kotero kuti chozizira ndi mpope wamadzimadzi mu chitoliro cha madzi, choziziritsa kuzizira sichimadutsa pa radiator, uku ndikuzungulira pang'ono, pamene kutentha kwa choziziritsa kumafika madigiri 87 (Bora thermostat yotseguka kutentha kwa madigiri 87, Pambuyo pake, valavu ya thermostat imatsegulidwa, choziziritsa kukhosi chimayamba kuyenda mu radiator, ndipo dongosolo loziziritsa limalowa mkombero waukulu Nthawi zambiri, pafupifupi mphindi zisanu galimoto itayamba, kutentha koziziritsa kumatha kufika madigiri 85 ~ 105, ngati kutentha kwabwinoko sikunachitike. zafikiridwa kwa nthawi yayitali, kapena kutentha kwakwera kuposa madigiri a 110, ziyenera kuganiziridwa ngati thermostat ndi yolakwika.
Chonde tiyimbireni ngati mukufuna such mankhwala.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zolandiridwa kuti mugule.
