Thermostat ni valve igenzura inzira y'amazi akoreshwa mu gukonjesha. Ni igikoresho gihindura ubushyuhe cyikora, ubusanzwe kiba kirimo igice gipima ubushyuhe, gifungura kandi kikazimya urujya n'uruza rw'umwuka, gazi cyangwa amazi binyuze mu kwaguka k'ubushyuhe cyangwa gukonjesha.
Thermostat ihindura ingano y'amazi yinjira muri radiator hakurikijwe ubushyuhe bw'amazi akonje, kandi igahindura urwego rw'amazi azenguruka kugira ngo ihindure ubushobozi bwo gusohora ubushyuhe bw'uburyo bukonjesha kandi irebe ko moteri ikora mu rugero rukwiye rw'ubushyuhe. Thermostat igomba kuguma mu buryo bwiza, bitabaye ibyo byagira ingaruka zikomeye ku mikorere isanzwe ya moteri. Iyo valve nkuru ya thermostat ifunguwe bitinze, bizatuma moteri ishyuha cyane; iyo valve nkuru ifunguwe kare cyane, igihe cyo gushyushya moteri kizaba kirekire kandi ubushyuhe bwa moteri buzaba buri hasi cyane.
Muri rusange, inshingano ya thermostat ni ukurinda moteri gukonja cyane. Urugero, nyuma yuko moteri ikora neza, ubushyuhe bwa moteri bushobora kuba buri hasi cyane iyo nta thermostat ihari mu gihe cy'itumba. Muri iki gihe, moteri igomba guhagarika by'agateganyo kudatembera kw'amazi kugira ngo ubushyuhe bwa moteri bube buke cyane.
Uburyo thermostat ya wax ikora
Thermostat nyamukuru ikoreshwa ni thermostat yo mu bwoko bwa wax. Iyo ubushyuhe bwo gukonjesha buri hasi y’agaciro kagenwe, parafini itunganyijwe mu mubiri upima ubushyuhe bwa thermostat iba ikomeye, kandi valve ya thermostat irafungwa hagati ya moteri na radiator munsi y’ingufu z’isoko. Konjesha isubizwa muri moteri binyuze kuri pompe y’amazi kugira ngo igere ku rugero ruto muri moteri. Iyo ubushyuhe bw’ikonjesha bugeze ku gaciro kagenwe, parafini itangira gushonga buhoro buhoro ikaba amazi, kandi ingano iriyongera kandi umuyoboro wa rubber ugakandamizwa kugira ngo ugabanye. Iyo umuyoboro wa rubber ugabanutse, hashyirwa imbaraga hejuru ku mushumi, maze agapfundikizo gashyirwa hasi kuri valve kugira ngo gafungure valve. Muri iki gihe, coolant inyura muri radiator na valve ya thermostat, hanyuma igasubira muri moteri inyuze muri pompe y’amazi kugira ngo ikore urugendo rurerure. Thermostat nyinshi ziba ziri mu muyoboro w’amazi w’umutwe wa silindiri. Akamaro k’ibi ni uko imiterere yazo yoroshye, kandi byoroshye gukuraho utubumbe tw’umwuka muri sisitemu yo gukonjesha; ikibi ni uko thermostat ikunze gufungurwa no gufungwa mu gihe cyo gukora, bigatuma habaho kwizunguruka.
Urubanza rwa Leta
Iyo moteri itangiye gukonja, niba hari amazi akonje asohoka mu muyoboro winjira mu cyumba cyo hejuru cy'amazi cyo mu kigega cy'amazi, bivuze ko valve nkuru ya thermostat idashobora gufungwa; iyo ubushyuhe bw'amazi akonje ya moteri burenze 70 ℃, icyumba cyo hejuru cy'amazi cyo mu kigega cy'amazi kirinjira. Iyo nta mazi akonje asohoka mu muyoboro w'amazi, bivuze ko valve nkuru ya thermostat idashobora gufungurwa mu buryo busanzwe, kandi hakenewe gusanwa muri iki gihe. Igenzura rya thermostat rishobora gukorwa ku modoka ku buryo bukurikira:
Igenzura nyuma yo gutangira moteri: Fungura igipfundikizo cy'amazi yinjira muri radiateri, niba urwego rwo gukonjesha muri radiateri rudahinduka, bivuze ko thermostat ikora neza; bitabaye ibyo, bivuze ko thermostat idakora neza. Ibi biterwa nuko iyo ubushyuhe bw'amazi buri munsi ya 70°C, silinda yo kwagura ya thermostat iba iri mu mimerere yo gufunga kandi vali nkuru irafunze; iyo ubushyuhe bw'amazi buri hejuru ya 80°C, silinda yo kwagura iraguka, vali nkuru irafunguka buhoro buhoro, maze amazi azenguruka muri radiateri atangira gutemba. Iyo igipimo cy'ubushyuhe bw'amazi kigaragaza ko ari munsi ya 70°C, niba hari amazi atemba ku muyoboro w'amazi yinjira muri radiateri kandi ubushyuhe bw'amazi bukaba bushyushye, bivuze ko vali nkuru ya thermostat idafunze neza, bigatuma amazi akonje atembera mbere y'igihe.
Genzura nyuma y’uko ubushyuhe bw’amazi buzamutse: Mu ntangiriro z’imikorere ya moteri, ubushyuhe bw’amazi buzamuka vuba; iyo igipimo cy’ubushyuhe bw’amazi kigaragaje 80, umuvuduko w’ubushyuhe uragabanuka, bigaragaza ko thermostat ikora neza. Ahubwo, niba ubushyuhe bw’amazi bwakomeje kwiyongera cyane, iyo igitutu cy’imbere kigeze ku rugero runaka, amazi abira arahita yuzura, bivuze ko valve nyamukuru ifata igahita ifungurwa.
Iyo igipimo cy'ubushyuhe bw'amazi kigaragaza 70°C-80°C, fungura igipfundikizo cya radiator n'icyuma gifunga imiyoboro ya radiator, hanyuma wumve ubushyuhe bw'amazi n'intoki. Niba byombi bishyushye, bivuze ko thermostat ikora neza; niba ubushyuhe bw'amazi ku gice cy'amazi cya radiator buri hasi, kandi radiator yuzuye. Niba nta mazi atemba cyangwa amazi make atemba ku muyoboro w'amazi wo mu cyumba, bivuze ko valve nyamukuru ya thermostat idashobora gufungurwa.
Thermostat ifata cyangwa idafunze neza igomba gukurwaho kugira ngo isukurwe cyangwa ikosorwe, kandi ntigomba guhita ikoreshwa.
Igenzura rihoraho
Imiterere y'ihinduranya rya thermostat
Imiterere y'ihinduranya rya thermostat
Amakuru avuga ko ubuzima bw'umuyoboro wa wax thermostat muri rusange ari 50.000km, bityo ikaba isabwa gusimbuzwa buri gihe bitewe n'ubuzima bwayo bwiza.
Aho thermostat iherereye
Uburyo bwo kugenzura thermostat ni ukureba ubushyuhe bw'ifungura, ubushyuhe bwuzuye bufunguye no kuzamura valve nkuru ya thermostat mu bikoresho bishyushya ubushyuhe buhoraho bushobora guhindurwa. Iyo kimwe muri byo kitujuje agaciro kagenwe, thermostat igomba gusimbuzwa. Urugero, kuri thermostat ya moteri ya Santana JV, ubushyuhe bw'ifungura valve nkuru ni 87°C hejuru cyangwa 2°C munsi, ubushyuhe bwuzuye bufunguye ni 102°C hejuru cyangwa 3°C munsi, naho kuzamura valve nzima ni >7mm.
Imiterere ya thermostat
Muri rusange, icyuma gikonjesha cy’uburyo bwo gukonjesha amazi gituruka mu mubiri kigasohoka mu mutwe wa silindiri. Ibyuma byinshi bikonjesha biba biri mu murongo w’aho umutwe wa silindiri usohoka. Akamaro k’iyi gahunda ni uko imiterere yayo yoroshye, kandi byoroshye gukuraho utubumbe tw’umwuka mu buryo bwo gukonjesha amazi; ikibi ni uko habaho kuzunguruka iyo thermostat ikora.
Urugero, iyo utangije moteri ikonje mu gihe cy'itumba, valve ya thermostat irafungwa bitewe n'ubushyuhe buke bwa coolant. Iyo coolant iri mu gihe gito, ubushyuhe buriyongera vuba kandi valve ya thermostat irakinguka. Muri icyo gihe, coolant ifite ubushyuhe buke iri muri radiator irasohoka mu mubiri, bityo coolant yongera gukonja, na valve ya thermostat irakinguka. Iyo ubushyuhe bwa coolant bwongeye kuzamuka, valve ya thermostat irakinguka. Kugeza igihe ubushyuhe bwa coolant yose buhagaze neza, valve ya thermostat irahinduka kandi ntizongera gukinguka no gufunga kenshi. Ikintu cy'uko valve ya thermostat ifungurwa kandi igafungwa kenshi mu gihe gito cyitwa thermostat oscillation. Iyo iki kintu kibaye, kizongera ikoreshwa rya lisansi mu modoka.
Thermostat ishobora kandi gushyirwa mu muyoboro w'amazi wa radiator. Iyi gahunda ishobora kugabanya cyangwa gukuraho ingaruka zo kuzunguruka kwa thermostat, kandi igashobora kugenzura neza ubushyuhe bwa coolant, ariko imiterere yayo ni igoye kandi ikiguzi ni kinini, kandi ikoreshwa cyane mu modoka zikora neza n'imodoka zikunze kugenda ku muvuduko mwinshi mu gihe cy'itumba.

Ivugurura rya Thermostat ya Wax
Iterambere mu bice bya Drive bigenzurwa n'ubushyuhe
Kaminuza y’Ubwubatsi n’Ikoranabuhanga ya Shanghai yateguye ubwoko bushya bwa thermostat ifite thermostat ya parafini nk’umubiri wayo n’icyuma gikozwe mu buryo bwa cylindrical coil-shaped coil-shape memory alloy ishingiye ku bushyuhe nk’ikintu gitwara ubushyuhe. Thermostat ibogamira isoko iyo ubushyuhe bwa silinda yo gutangira imodoka buri hasi, kandi impera y’icyuma gikonjesha ituma valve nkuru ifunga kandi valve yunganira igafungura ku ruziga ruto. Iyo ubushyuhe bwa coolant buzamutse ku gaciro runaka, spring y’icyuma gikonjesha irakura kandi igakanda bias. Spring ituma valve nkuru ya thermostat ifungura, kandi uko ubushyuhe bwa coolant bwiyongera, ifungura valve nkuru rigenda ryiyongera buhoro buhoro, kandi valve yunganira ifunga buhoro buhoro kugira ngo ikore uruziga runini.
Nk'igikoresho cyo kugenzura ubushyuhe, iyi aloyi yo kwibuka ituma igikorwa cyo gufungura valve gihinduka neza ukurikije ubushyuhe, ibi bikaba ingirakamaro mu kugabanya ingaruka z'ubushyuhe bw'amazi akonjesha mu kigega cy'amazi kiri kuri silinda iyo moteri itangiye gutwika, kandi icyarimwe bikongera ubuzima bwa thermostat. Ariko, thermostat irahindurwa hashingiwe kuri thermostat ya wax, kandi imiterere y'ikintu cyo kugenzura ubushyuhe igarukira ku rugero runaka.
Kunoza Valve
Thermostat igira ingaruka ku mazi akonjesha. Kubura amazi akonjesha atemba muri thermostat bituma moteri ikoresha umuriro itakaza ingufu, ibyo bikaba bitakwirengagizwa. Valve ikozwe nk'umugozi muto ufite imyobo ku rukuta rwo ku ruhande, kandi umuyoboro w'amazi ukorwa n'umwobo wo ku ruhande n'umwobo wo hagati, kandi umuringa cyangwa aluminiyumu bikoreshwa nk'ibikoresho bya valve kugira ngo ubuso bwa valve burusheho kuba bwiza, kugira ngo bigabanye ubukana no kunoza ubushyuhe bw'igikoresho.
Uburyo bwo kunoza imikorere y'urujya n'uruza rw'amazi mu buryo bwo gukonjesha
Uburyo bwiza bwo gukora ubushyuhe bwa moteri ikoresha umuriro ni uko ubushyuhe bw'umutwe wa silinda buba buri hasi kandi ubushyuhe bwa silinda bukaba buri hejuru. Kubera iyo mpamvu, sisitemu yo gukonjesha iai iragaragara, kandi imiterere n'aho thermostat ishyirwa bigira uruhare runini muri byo. Imiterere y'imikoranire y'imikoreshereze ya thermostat, thermostat ebyiri zishyirwa ku gice kimwe, sensor y'ubushyuhe ishyirwa kuri thermostat ya kabiri, 1/3 cy'umuvuduko w'umukonjesha ukoreshwa mu gukonjesha block ya silinda, 2/3 Umuvuduko w'umukonjesha ukoreshwa mu gukonjesha umutwe wa silinda.
