Cable Glands ua haujlwm li cas?

cas 1

Taw qhia
Cable caj pas yog cov cuab yeej uas tseem ceeb heev thaum txiav cov cables hauv qhov hnyav lossis teeb meem.
Qhov no yog qhov uas sealing, ingress tiv thaiv thiab yog vim li cas cable caj pas yog earthing yuav tsum tau.
Nws lub luag haujlwm yog kom muaj kev nyab xeeb hla lub raj, xaim, lossis cable los ntawm qhov chaw kaw.
Lawv muab kev daws teeb meem thiab tseem ua kom muaj cov nplaim taws lossis cov khoom siv hluav taws xob uas yuav tshwm sim hauv qhov chaw muaj kev phom sij.

Dab tsi ntxiv:
Lawv kuj ua raws li lub foob, txwv tsis pub sab nrauv impurities los ntawm kev ua rau muaj kev puas tsuaj rau cov hluav taws xob thiab cov cable.
Qee yam ntawm cov kab mob no yog:

  • kua dej,
  • av,
  • hmoov av

Thaum kawg, lawv nres cables los ntawm rub thiab twisted ntawm lub tshuab.
Tias yog vim lawv pab kom muaj kev nyab xeeb thiab ruaj khov kev sib txuas ntawm lub tshuab thiab cable uas nws txuas nrog.

Hauv phau ntawv qhia no, peb yuav pab koj nkag siab zoo dua li cas cov qog ua haujlwm cable.
Cia peb pib.

Cable Glands thiab Cable Gland Parts
Cable caj pas yog lub npe hu ua 'mechanical cable entry devices' uas yog siv ua ke nrog rau kev xaim thiab cable rau:

  • automation systems (xws li cov ntaub ntawv, telecoms, hwj chim, teeb pom kev zoo)
  • hluav taws xob, ntsuas & tswj

Lub luag haujlwm tseem ceeb ntawm lub caj pas cable yog los ua kev sib khi thiab txiav cov cuab yeej.
Nws ua kom muaj kev tiv thaiv ntawm cov ntaub thaiv npog thiab cov khoom siv hluav taws xob, suav nrog kev xa khoom ntawm:

  • Ntxiv ib puag ncig sealing

Ntawm qhov chaw nkag cable, khaws cov kev tiv thaiv ingress ntawm lub thawv nrog cov khoom siv tsim nyog tau cog lus los ua lub hom phiaj no

Cable caj pas hauv automation tshuab

  • Ntxiv sealing

Nyob rau hauv cheeb tsam ntawm lub cable tuaj txog ntawm lub enclosure, yog hais tias yuav tsum tau ib tug siab ntawm ingress tiv thaiv

  • tuav quab yuam

Nyob rau hauv lub cable kom lav txaus theem ntawm txhua yam cable 'rub tawm' kuj

  • Lub ntiaj teb txuas ntxiv

Nyob rau hauv cov ntaub ntawv ntawm ib tug armored cable, thaum lub cable caj pas nta ib tug hlau qauv.
Nyob rau hauv tas li ntawd, cable caj pas tej zaum yuav raug kuaj kom paub tseeb tias lawv muaj peev xwm tiv tau ib tug txaus ncov luv luv Circuit Court tam sim no.

  • Kev tiv thaiv ib puag ncig

Los ntawm kev sib khi ntawm sab nrauv cable sheath, tsis suav nrog cov dej noo thiab plua plav los ntawm cov cuab yeej lossis cov khoom siv hluav taws xob

Koj pom:
Cable caj pas tuaj yeem ua los ntawm cov hlau tsis yog hlau rau cov khoom siv hlau.
Los yog nws tuaj yeem yog qhov sib xyaw ntawm ob qho tib si uas kuj tuaj yeem tiv taus corrosion.
Nws tau txiav txim los ntawm kev sau mus rau tus qauv, lossis los ntawm kev txheeb xyuas corrosion resistant.

Yog tias siv rau hauv qhov chaw tawg hauv qhov tshwj xeeb, nws yog ib qho tseem ceeb uas cov qog nqaij hlav tau pom zoo rau cov kev xaiv ntawm cable.
Lawv kuj yuav tsum khaws cov qib kev tiv thaiv ntawm cov cuab yeej uas lawv txuas nrog.

Ib qho tseem ceeb tshaj plaws txog cov kab mob qog noj ntshav yog tias lawv muaj IP68 tsis muaj dej tsis zoo.
Qhov ntawd txhais tau hais tias lawv tuaj yeem siv tau los ua cov ntsiab lus tawm dej tsis zoo los ntawm cov ntaub thaiv ib puag ncig hnyav thiab tsis zoo thiab dhau los ntawm cov bulkheads.

Rau koj siv lawv:
Cable caj pas compresses ib lub foob rau hauv lub voj voog kab.
Nws nres ingress ntawm cov khoom los yog dej uas yuav ua rau puas tsuaj mus ib txhis rau cov khoom siv hluav taws xob.

Piv txwv li:
Yog tias koj yuav tsum tau hla lub cable mus rau hauv lub qhov dej tsis muaj dej, koj yuav tsum tau laum ib lub qhov rau hauv lub thawv.
Qhov ntawd tiag ua rau nws tsis muaj dej ntxiv lawm.
