Dab tsi yog Waterproof IP Rating?
Peb vam khom cov dej tsis zoo los tiv thaiv peb txoj kev nplij siab thiab kev nyab xeeb hauv ntau yam ntawm lub neej. Cov huab cua tawm ntawm lub tsheb tiv thaiv txhua tus neeg sab hauv kom tsis txhob ntub thaum lawv tsav los nag los nag. Thaum peb yuav tsum tawm hauv huab cua ntub, peb ua tsaug rau cov tsho tsis muaj dej. Lub ru tsev zoo tiv thaiv dej los ntawm kev puas tsuaj rau peb lub tsev thiab kev lag luam.
Los ntawm tib lub cim, nws yog ib qho tseem ceeb rau txhua tus tsim cov khoom siv hluav taws xob thiab / lossis cov tshuab hluav taws xob kom paub txog IP dej tsis kam. Qhov ntsuas ntsuas no muab txoj hauv kev yooj yim los ntsuas seb cov ntaub thaiv dej tsis zoo tiv thaiv kev sib tsoo, hose txau, submersion thiab lwm yam dej phom sij uas cov khoom siv hluav taws xob feem ntau ntsib.
Hauv phau ntawv qhia no, peb yuav muab koj cov ntsiab lus luv luv ntawm IP dej tsis kam ntsuas thiab lawv ua haujlwm li cas. Xav tau ib lub thawv hluav taws xob tsis zoo rau koj qhov project? Peb kuj tseem yuav tham txog Honfa qhov kev xaiv ntawm IP ntsuas dej tsis zoo thiab yuav ua li cas lawv tuaj yeem pab tiv thaiv koj cov khoom siv rhiab tshaj plaws.
Qhov Kev Ntsuas IP yog dab tsi?
Kev ntsuam xyuas IP yog ob tus lej kev ua tau zoo rau cov khoom siv hluav taws xob lossis qhov chaw kaw. Cov kev ntsuam xyuas no muab cov ntaub ntawv tseem ceeb hais txog qib kev tiv thaiv uas ib lub tsev thaiv muab tiv thaiv kev nkag los ntawm ob chav kawm ntawm kev phom sij: khoom ingress thiab kua dej ingress. Qee qhov piv txwv suav nrog IP55 thiab IP67, txawm hais tias muaj ntau qhov kev ntsuas tau.
Ob tus lej ntawm txhua qhov kev ntsuas IP ua haujlwm raws li hauv qab no:
Thawj tus lej yog cov khoom tiv thaiv ingress, uas suav nrog kev tiv thaiv tiv thaiv kev sib tsoo, plua plav, khib nyiab thiab lwm yam khoom siv, ntsuas ntawm qhov nce qib ntawm 0 mus rau 6.
Tus lej thib ob yog qhov ntsuas dej tsis kam, uas ntsuas nws qhov kev tiv thaiv tawm tsam cov dej nkag ntawm qhov nce qib ntawm 0 mus rau 9.
Txhua qib ntawm cov nplai sib raug rau ib qib tshwj xeeb ntawm kev tiv thaiv dej ingress. Piv txwv li, tus lej 7 hauv tus lej thib ob txhais tau hais tias lub kaw lus muab kev tiv thaiv ib ntus submersion ntawm qhov tob txog li ib meter.
Degrees ntawm IP Dej Resistance
Nov yog cov lus qhia ceev ceev ntawm cov theem ntawm cov dej tsis kam hauv IP nplai, raws li tau piav qhia hauv tus lej IP kev ntsuas tus lej:
IPx0: Tsis muaj kev tiv thaiv dej
IPx1: Tiv thaiv cov dej ntws tawm ntsug
IPx2: Tiv thaiv cov vertically ntog dej poob thaum enclosure tilted mus txog 15º
IPx3: Tiv thaiv cov dej txau
IPx4: Tiv thaiv cov dej txaws
IPx5: Tiv thaiv cov dav hlau dej
IPx6: Tiv thaiv cov dav hlau dej muaj zog
IPx7: Tiv thaiv qhov cuam tshuam ntawm kev nkag mus rau hauv dej ib ntus
IPx8: Tiv thaiv cov teebmeem ntawm kev immersion tas li hauv dej
IPx9: Tiv thaiv kev kub siab thiab kub dej dav hlau
Nco ntsoov tias qhov ntsuas IPx9 tsis tshua siv. Ib cag ntawm cov ntawv thov tshwj xeeb me me uas siv IP69K enclosures, feem ntau cov ntawv thov kho IP68 raws li qhov ntsuas IP siab tshaj plaws.
Gasket Foob: Ntau tus IP ntsuas cov ntaub ntawv siv lub silicone roj hmab gasket los kaw cov dej. Lub gasket haum rau hauv qhov zawj hauv lub thawv thiab tiv thaiv dej los ntawm kev nkag los ntawm lub qhov rooj ntawm cov seams los yog panels.
Mated Parts: IP rated enclosures feem ntau tsim nrog cov khoom sib txuas uas haum ua ke nruj. Qhov chaw nruj ua rau nws yooj yim dua rau cov dej nkag mus rau hauv lub qhov rooj, thiab nws tuaj yeem txhim kho qhov thaiv kev ruaj ntseg.
Adhesives: Siv cov nplaum nplaum nplaum nplaum nplaum rau qhov chaw ntawm lub qhov rooj ua ke tuaj yeem txhim kho nws cov dej tsis kam.
IP Rated Accessories: Rau cov ntaub ntawv siv los ua cov thawv sab nraum zoov lossis rau lwm daim ntawv thov uas yuav tsum tau txiav tawm thiab hla dhau, cov khoom siv xws li cov qog thiab cov vents yog qhov tseem ceeb rau kev tuav pov hwm tus IP ntsuas. Txhawm rau kom paub tseeb tias koj cov khoom siv hauv tsev yog nyob ntawm txoj haujlwm, nrhiav cov khoom siv uas muaj IP ntsuas lawv tus kheej.
PCB Potting thiab Conformal Txheej: Cov cuab yeej tsim qauv siv cov kev tiv thaiv no los muab lawv cov cuab yeej IP ntsuas kev ua tau zoo. Los ntawm kev sau cov ntaub thaiv npog nrog qee cov dej tsis sib txuas (lub npe hu ua PCB potting) lossis txheej nws cov khoom nrog cov yeeb yaj kiab tiv thaiv dej (lub npe hu ua conformal txheej), cov tuam txhab tsim khoom tuaj yeem pab tiv thaiv lub qhov rooj ntawm cov khoom ntawm dej.
Hmoov zoo, Hongfa ua rau nws yooj yim mus nrhiav ib qho chaw nrog tus IP ntsuam xyuas koj xav tau lossis zoo dua. Peb tsim peb cov enclosures kom muab qhov siab tshaj plaws IP kev ua tau rau lawv tsim. Ntau yam ntawm peb cov qauv enclosure muaj qhov ntsuas IP siab dua xws li IP66 thiab IP68 ntxiv rau qhov qis dua. Yog li, tsis muaj teeb meem dab tsi IP ntsuam xyuas koj daim ntawv thov xav tau, Hongfa muaj cov txheej txheem kho kom haum rau koj.
Lus Cim: Ntau cov khoom siv hluav taws xob yuav tsum muaj kev tiv thaiv ingress, ib yam nkaus. Saib pebqhia rau plua plav pov thawj IP ntsuasthiab pebua kom tiav daim ntawv qhia kev ntsuas IPrau cov ntaub ntawv ntau ntxiv los pab koj xaiv txoj cai ntawm tus IP rated enclosure.
