yuav ua li cas sib nqus locks ua haujlwm

Sib nqus locks, tseem hu ua electromagnetic locks, yog ib hom kev kaw lus uas siv cov hluav taws xob tam sim no kom lub qhov rooj ruaj ntseg. Cov xauv no muaj ob lub ntsiab lus - electromagnet thiab armature phaj - uas ua hauj lwm ua ke los muab kev ruaj ntseg thiab txhim khu kev qha kev daws teeb meem.

Lub electromagnet feem ntau yog ntsia rau ntawm lub qhov rooj thiab yog ua los ntawm ib tug coil ntawm hlau uas yog qhwv ib ncig ntawm ib tug hlau core. Thaum cov hluav taws xob tam sim no dhau los ntawm lub kauj, nws tsim ib qho chaw sib nqus muaj zog uas nyiam cov phaj armature.

Lub armature phaj yog nyob rau ntawm lub qhov rooj nws tus kheej thiab yog ua los ntawm ib tug hlau uas yog attracted rau lub magnetic teb tsim los ntawm cov electromagnet. Thaum lub tshuab electromagnet tau qhib, lub phaj armature yog rub mus rau ntawm lub xauv, tsim kom muaj kev ruaj ntseg uas ua rau lub qhov rooj kaw.

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov xauv hlau nplaum yog tias lawv muaj kev ntseeg siab heev. Tsis zoo li cov locks ib txwm muaj tuaj yeem khaws lossis cuam tshuam nrog, cov xauv hlau nplaum yog qhov tsis tuaj yeem kov yeej yam tsis muaj cov cuab yeej tsim nyog lossis kev paub. Qhov no ua rau lawv xaiv qhov zoo tshaj plaws rau kev siv kev nyab xeeb siab, xws li tsoomfwv cov tsev, tsev txhab nyiaj, thiab cov chaw khaws ntaub ntawv.

Lwm qhov zoo ntawm cov xauv hlau nplaum yog tias lawv yooj yim rau nruab thiab tswj. Tsis zoo li cov locks ib txwm siv uas yuav tsum tau muab tso rau hauv qhov tseem ceeb thiab tig, cov xauv hlau nplaum tuaj yeem yooj yim programmed siv lub vaj huam sib luag tswj. Qhov no tso cai rau cov neeg siv tau yooj yim tso cai lossis tshem tawm kev nkag mus rau cov tib neeg tshwj xeeb lossis pab pawg neeg, ua rau lawv xaiv qhov zoo tshaj plaws rau cov lag luam lossis cov koom haum uas xav tau tswj kev nkag mus rau qee thaj chaw.
