Ukutshintsha kweqondo lobushushu okanye ukutshintsha kwe-thermal kusetyenziselwa ukuvula nokuvala abafowunelwa bokutshintsha. Ubume bokutshintsha kweqondo lokushisa liyatshintsha ngokuxhomekeke kwiqondo lokushisa. Lo msebenzi usetyenziswa njengokhuselo lokutshisa okanye ukupholisa. Ngokusisiseko, ukutshintshwa kwe-thermal kunoxanduva lokubeka iliso kubushushu bomatshini kunye nezixhobo kwaye zisetyenziselwa ukunciphisa ubushushu.
Zeziphi iintlobo zokutshintsha kobushushu ezikhoyo?
Ngokubanzi, kwenziwa umahluko phakathi kokutshintsha oomatshini kunye ne-elektroniki. Ukutshintsha kweqondo lokushisa lomatshini kuyahluka kwiimodeli ezahlukeneyo zokutshintsha, ezifana nokutshintsha kobushushu be-bimetal kunye nokutshintsha kweqondo lokushisa kwegesi. Xa ukuchaneka okuphezulu kufunwa, kufuneka kusetyenziswe utshintsho lobushushu be-elektroniki. Apha, umsebenzisi unokutshintsha ixabiso lomda ngokwabo kwaye usete amanqaku amaninzi okutshintsha. Ukutshintsha kweqondo lokushisa kweBimetal, ngakolunye uhlangothi, kusebenza ngokuchaneka okuphantsi, kodwa kuhambelana kakhulu kwaye kungabizi. Enye imodeli yokutshintsha i-gas-activated temperatures switch, esetyenziswa ngokukodwa kwizicelo ezikhuselekileyo zokhuseleko.
Uthini umahluko phakathi kokutshintsha kweqondo lokushisa kunye nesilawuli sobushushu?
Umlawuli weqondo lokushisa, usebenzisa i-probe yeqondo lokushisa, ufumanisa iqondo lobushushu langempela kwaye lithelekise nendawo emiselweyo. Indawo yokumisela efunekayo ihlengahlengiswa nge-actuator. Umlawuli wobushushu ke ngoko unoxanduva lokubonisa, ukulawula nokubeka iliso kumaqondo obushushu. Ukutshintsha kobushushu, ngakolunye uhlangothi, kubangela ukusebenza kokutshintsha ngokuxhomekeke kwiqondo lokushisa kwaye zisetyenziselwa ukuvula nokuvala iisekethe.
Yintoni ukutshintsha ubushushu bebimetal?
Ukutshintsha kweqondo lokushisa kweBimetal kumisela ubushushu usebenzisa i-bimetal disc. Ezi ziquka iintsimbi ezimbini, ezisetyenziswa njengemicu okanye iiplatelet kwaye zinee-coefficients ze-thermal ezahlukeneyo. Iintsimbi zivame ukusuka kwi-zinc kunye nentsimbi okanye ubhedu kunye nentsimbi. Xa, ngenxa yokunyuka kobushushu be-ambient, iqondo lokushisa eliqhelekileyo lifikelelwa, i-bimetal disc itshintsha kwindawo yayo eguqukayo. Emva kokupholisa umva ukuya kwiqondo lokushisa lokutshintsha ngokutsha, utshintsho lobushushu lubuyela kwimeko yalo yangaphambili. Ukutshintsha kweqondo lokushisa kunye ne-latching yombane, ukunikezelwa kombane kuphazamisekile ngaphambi kokutshintsha umva. Ukuze ufezekise ukucocwa okuphezulu komnye nomnye, ii-discs zine-concave-shaped xa zivulekile. Ngenxa yempembelelo yokushisa, i-bimetal deforms kwi-convex direction kunye neendawo zoqhagamshelwano zingathintana ngokukhuselekileyo. Ukutshintsha kobushushu beBimetal kunokongezwa njengokhuseleko lobushushu obugqithisileyo okanye njenge fuse ye-thermal.
Isebenza njani i-bimetal switch?
Ukutshintsha kweBimetallic kuqulethwe yimichilo emibini yeentsimbi ezahlukeneyo. Imichilo ye-bimetal idityaniswe ngokungenakuhlukaniswa. Umcu uquka umfowunelwa osisigxina kunye nomnye umfowunelwa kwi-bimetal strip. Ngokugoba imichilo, i-snap-action switch iyasebenza, eyenza ukuba isiphaluka sivulwe kwaye sivalwe kwaye inkqubo iqaliswe okanye iphelile. Kwezinye iimeko, ukutshintshwa kobushushu be-bimetal ayifuni utshintsho lwe-snap-action, njengoko iiplatelet sele zigobile ngokufanelekileyo kwaye ngaloo ndlela sele zinentshukumo ekhawulezayo. Izitshixo zeBimetal zisetyenziswa njenge thermostats kwi-automatic circuit breakers, irons, coffee machines okanye izifudumezi fan.
