Qhov kub hloov pauv yog dab tsi?

Lub qhov kub thiab txias hloov los yog thermal hloov yog siv los qhib thiab kaw kev sib cuag. Cov xwm txheej hloov pauv ntawm qhov kub hloov pauv hloov nyob ntawm qhov ntsuas kub nkag. Cov haujlwm no yog siv los tiv thaiv overheating lossis overcooling. Yeej, cov thermal hloov pauv yog lub luag haujlwm rau kev saib xyuas qhov kub thiab txias ntawm cov tshuab thiab cov khoom siv thiab siv rau kev txwv kub.

Hom kev hloov pauv kub muaj dab tsi?

Feem ntau, qhov sib txawv yog ua los ntawm cov tshuab hluav taws xob thiab hluav taws xob hloov. Lub tshuab ntsuas kub hloov pauv txawv nyob rau hauv ntau yam hloov qauv, xws li bimetal kub keyboards thiab gas-actuated kub keyboards. Thaum yuav tsum tau muaj qhov raug siab, yuav tsum siv lub tshuab hluav taws xob hloov hluav taws xob. Ntawm no, tus neeg siv tuaj yeem hloov pauv tus nqi txwv lawv tus kheej thiab teeb tsa ob peb lub ntsiab lus hloov. Bimetal kub hloov pauv, ntawm qhov tod tes, ua haujlwm nrog qhov raug qis, tab sis muaj kev cog lus thiab pheej yig heev. Lwm tus qauv hloov pauv yog qhov hloov pauv roj-ua kom sov, uas yog siv tshwj xeeb hauv kev siv kev nyab xeeb-tseem ceeb.

Dab tsi yog qhov txawv ntawm qhov ntsuas kub thiab qhov ntsuas kub?

Lub tshuab ntsuas kub tuaj yeem, siv qhov ntsuas kub ntsuas, txiav txim siab qhov ntsuas kub tiag tiag thiab tom qab ntawd muab piv nrog cov ntsiab lus teeb tsa. Qhov xav tau teeb tsa tau hloov kho los ntawm tus actuator. Tus tswj qhov kub thiab txias yog li lub luag haujlwm rau cov zaub, tswj thiab saib xyuas qhov kub thiab txias. Kub hloov pauv, ntawm qhov tod tes, ua rau kev hloov pauv nyob ntawm qhov ntsuas kub thiab siv los qhib thiab kaw circuits.

Dab tsi yog qhov hloov pauv bimetal kub?

Bimetal kub keyboards txiav txim siab qhov kub uas siv bimetal disc. Cov no muaj ob lub hlau, uas yog siv los ua ib daim hlab lossis platelets thiab muaj cov thermal coefficients sib txawv. Cov hlau feem ntau yog los ntawm zinc thiab hlau los yog tooj dag thiab hlau. Thaum, vim qhov kub thiab txias, qhov nominal hloov pauv mus txog, lub bimetal disc hloov mus rau hauv nws txoj haujlwm rov qab. Tom qab txias rov qab mus rau qhov pib hloov pauv qhov kub thiab txias, qhov hloov pauv kub rov qab mus rau nws lub xeev dhau los. Rau qhov kub thiab txias hloov nrog hluav taws xob latching, lub hwj huam mov yog cuam tshuam ua ntej hloov rov qab. Yuav kom ua tiav qhov siab tshaj plaws clearance ntawm ib leeg, cov discs yog concave-puab thaum qhib. Vim yog cov nyhuv ntawm cov cua sov, cov bimetal deforms nyob rau hauv lub convex kev taw qhia thiab cov chaw sib cuag tau ruaj ntseg kov ib leeg. Bimetal kub keyboards kuj tseem siv tau los tiv thaiv overtemperature los yog thermal fuse.

Lub bimetal hloov ua haujlwm li cas?

Bimetallic keyboards muaj ob lub strips ntawm cov hlau sib txawv. Cov bimetal strips tau koom ua ke inseparably. Ib lub strip muaj ib qho kev sib cuag ruaj khov thiab lwm qhov kev sib cuag ntawm lub bimetal sawb. Los ntawm khoov cov strips, lub snap-action hloov yog actuated, uas enables lub Circuit Court qhib thiab kaw thiab ib tug txheej txheem pib los yog tas. Qee zaum, qhov kub ntawm bimetal keyboards tsis tas yuav tsum tau snap-action keyboards, raws li cov platelets twb nkhaus raws li thiab yog li twb muaj ib tug snap ua. Bimetal keyboards yog siv los ua cov ntsuas kub hauv cov tshuab hluav taws xob tsis siv neeg, cov tshuab hluav taws xob, tshuab kas fes lossis kiv cua cua sov.
