Nkhani Yophunzira Mwamsanga za Bimetallic Thermostat Operating Principle and Structure

Bimetallic thermostat ndi chipangizo choteteza chomwe chimagwiritsidwa ntchito kwambiri pazida zapakhomo. Nthawi zambiri amagwiritsidwa ntchito mu polojekitiyi. Zinganenedwe kuti mtengo wa chipangizochi siwokwera ndipo kapangidwe kake ndi kosavuta, koma kamakhala ndi gawo lalikulu kwambiri pa mankhwalawa.

Mosiyana ndi zida zina zamagetsi kuti amalize ntchitoyi, ntchito yaikulu kwambiri ya thermostat imakhala ngati chipangizo chotetezera, pokhapokha ngati makinawo ali osadziwika bwino, thermostat idzagwira ntchito, ndipo pamene makina akugwira ntchito bwino, thermostat sichidzagwira ntchito.

Chowongolera kutentha chomwe chimatsekedwa nthawi zambiri chimagwiritsidwa ntchito ngati chitsanzo. Kapangidwe kakakulu ka chowongolera kutentha ndi motere: chipolopolo chowongolera kutentha, mbale yophimba ya aluminiyamu, mbale ya bimetal, ndi ma wiring terminal.

Bimetallic pepala ndi moyo chigawo chimodzi cha bimetal thermostat, bimetallic pepala amapangidwa zidutswa ziwiri za zitsulo ndi osiyana matenthedwe kukula coefficients mbamuikha pamodzi, pamene kutentha mphamvu ya zitsulo pepala ukuwonjezeka, chifukwa zidutswa ziwiri za zitsulo matenthedwe kukula ndi kuzizira chidule digiri ndi zosagwirizana, kukanika kwa chidutswa cha zitsulo zotanuka ndi zitsulo zotanuka ndi kuonjezera mphamvu pang'onopang'ono. nthawi yomweyo mapindikidwe zidzachitika, kuti kukhudzana kwa pepala zitsulo ndi kukhudzana terminal anapatukana. Chotsani dera. Kutentha kumachepa pang'onopang'ono, mphamvu ya shrinkage ya chidutswa chachitsulo imawonjezeka pang'onopang'ono. Mphamvu ikakhala yayikulu kuposa chitsulo china, imayambitsanso mapindikidwe, omwe nthawi yomweyo amapangitsa kulumikizana kwachitsulo ndi kulumikizana komaliza kulumikizidwa, kuti chigawocho chitseguke.

Nthawi zambiri, pazida zapakhomo, ma thermostat osinthika amaphatikizidwa ndi zowongolera pamanja. Mwachitsanzo, ndi Kutentha chubu pa makina ochapira ndi ng'anjo, chifukwa kutentha padziko Kutentha chubu ndi mkulu kwambiri, ntchito ochiritsira kachipangizo kutentha ndi zambiri za mtengo kuwonjezeka, kuwonjezera kuonjezera kompyuta bolodi hardware mtengo ndi mapulogalamu kapangidwe zovuta, kotero resettable kutentha Mtsogoleri ndi Buku bimetal chotenthetsera chotenthetsera amakhala mtengo ndi ntchito mulingo woyenera kusankha.

Thermostat yobwezeretsedwa ikalephera, thermostat yamanja imatha kugwiritsidwa ntchito ngati chipangizo choteteza pawiri. M'mapangidwe ambiri azinthu, chotenthetsera chamanja chimangogwira ntchito ngati thermostat yokhazikika ikalephera. Chifukwa chake, chotenthetsera chamanja chikafunika kukhazikitsidwanso, wogwiritsa ntchito amatha kukumbutsidwa kuti awone ngati chipangizocho chikugwira ntchito molakwika.

Malinga ndi pamwamba dongosolo kuwonjezera, chifukwa osiyana kukula koyenelera wa bimetallic pepala, matenthedwe mphamvu mu makina mphamvu, ngati m'malo ndi kutentha tcheru madzi, kutentha kwaiye kuthamanga kusintha, thermistor ndi magwero ena kusintha, mukhoza amapeza osiyana kutentha Mtsogoleri.
