Sensor sealing yog hais txog kev ntsuas kev sib khi siv los tiv thaiv cov khoom siv sab hauv ntawm lub sensor los ntawm ib puag ncig sab nraud thiab tiv thaiv cov kua, roj, plua plav thiab impurities nkag mus rau hauv lub sensor. Lub hom phiaj ntawm sensor sealing yog los xyuas kom meej lub cev ua haujlwm ntawm lub sensor thiab nws lub peev xwm kom paub meej txog ib puag ncig tsis zoo.
- Sealing khoom: Sensor sealing feem ntau yog siv roj hmab, silicone, fluororubber lossis lwm yam khoom siv tshuaj-resistant sealing. Cov ntaub ntawv no muaj qhov zoo elasticity thiab hnav tsis kam, thiab tuaj yeem tiv thaiv kev nkag mus ntawm cov kua thiab roj.
- Sealing qauv: Cov qauv txheej txheem sib txawv tuaj yeem txais yuav, xws li O-ring foob, di ncauj foob, xov foob, thiab lwm yam. Cov qauv sealing tshwj xeeb yog txiav txim siab raws li tus qauv tsim thiab daim ntawv thov ntawm lub sensor thiab yog tsim los muab kev ruaj ntseg sealing kev ua tau zoo.
- Kev tiv thaiv qib: qib kev tiv thaiv feem ntau yog txiav txim siab raws li cov qauv thoob ntiaj teb (xws li IP qib). Qhov ntsuas IP qhia tias lub sensor tiv thaiv cov khoom thiab cov kua dej. Piv txwv li, IP67 txhais tau hais tias lub sensor tsis muaj plua plav thiab tsis muaj dej, thiab tuaj yeem ua haujlwm hauv qab dej mus rau qhov tob.
- Temperature resistance: Nws yuav tsum muaj qee qhov ntsuas kub kom haum rau qhov kev hloov pauv kub hauv qhov chaw ua haujlwm sib txawv. Sealing cov ntaub ntawv yuav tsum muaj peev xwm tswj tau lawv cov sealing kev ua tau zoo thiab lub cev muaj zog nyob rau hauv qhov kub thiab txias.
- Kev txhim kho thiab Kev Kho: Thaum txhim kho lub sensor, kev txhim kho kom raug thiab kev hloov kho ntawm lub foob yog qhov tseem ceeb los xyuas kom meej sealing kev ua tau zoo. Tsis tas li ntawd, kev tshuaj xyuas tsis tu ncua thiab kev saib xyuas ntawm kev ncaj ncees ntawm lub sensor foob yog ib kauj ruam tseem ceeb hauv kev tswj nws txoj haujlwm.
- Qhov zoo thiab kev ua tau zoo ntawm cov ntsaws ruaj ruaj sensor yog qhov tseem ceeb rau qhov tseeb thiab kev ntseeg tau. Thaum xaiv thiab siv lub foob foob, lub sensor qhov tshwj xeeb daim ntawv thov ib puag ncig, kev ua haujlwm, thiab cov qauv tsim nyog yuav tsum raug txiav txim siab los xyuas kom meej tias kev sib khi ua tau raws li qhov xav tau thiab ua tau raws li daim ntawv thov xav tau.
Dab tsi yog cov ntawv pov thawj thoob ntiaj teb rau cov ntsaws ruaj ruaj?
Cov ntawv pov thawj thoob ntiaj teb feem ntau suav nrog qib kev tiv thaiv (Ingress Protection, IP qib luv luv) cov qauv.
IP ntsuam xyuas yog ib tug dav siv thoob ntiaj teb tus qauv rau kev ntsuam xyuas thiab faib cov sensors, hluav taws xob khoom thiab qib sealing ntawm lawv enclosures. Nws qhia tias lub cuab yeej muaj peev xwm tiv thaiv cov khoom thiab cov kua dej. Cov hauv qab no yog ob peb hom ntawv pov thawj IP qib:
IP67: Qhov kev ntsuam xyuas no qhia tau hais tias lub sensor yog plua plav thiab dej tsis kam. Rau cov khoom siv (xws li hmoov av), nws muaj peev xwm tiv thaiv kom tsis txhob nkag ntawm cov khoom. Rau cov kua dej, nws muaj peev xwm ua hauj lwm hauv qab dej mus rau qhov tob thiab ua kom cov khoom sab hauv muaj kev nyab xeeb.
IP68: Qhov kev ntsuam xyuas no qhia tau hais tias lub sensor tiv taus plua plav thiab dej, thiab nruj dua li IP67.
Cov ntawv pov thawj IP no raug soj ntsuam thiab tau lees paub raws li IEC 60529 tus qauv muab los ntawm International Electrotechnical Commission (IEC).
Thaum xaiv lub sensor, ntxiv rau IP qib ntawv pov thawj, lwm yam yuav tsum tau txiav txim siab, xws li lub ntsuas ntsuas qhov tseeb, lub sijhawm teb, kev ua haujlwm kub, thiab lwm yam, kom tau raws li cov kev xav tau tshwj xeeb.
