Kodi Ma Cable Glands Amagwira Ntchito Bwanji?

Chiyambi
Ma cable glands ndi zida zofunika kwambiri potseka ma cable m'malo ovuta kapena oopsa.
Apa ndi pamene kutseka, chitetezo cha kulowa ndi chifukwa chake chingwe cha chingwe chikufunikira.
Ntchito yake ndi kupititsa chubu, waya, kapena chingwe mosamala kudzera mu mpanda.
Amapereka mpumulo ku kupsinjika ndipo amapangidwanso kuti aziphatikizapo malawi kapena zida zamagetsi zomwe zingachitike m'malo oopsa.

Komanso:
Amagwiranso ntchito ngati chosindikizira, kuletsa zinyalala zakunja kuti zisawononge makina amagetsi ndi chingwe.
Zina mwa zinthu zodetsa izi ndi izi:

• madzi,
• dothi,
• fumbi

Pamapeto pake, amaletsa zingwe kuti zisakokedwe ndi kupotozedwa kuchokera mu makinawo.
Izi zili choncho chifukwa zimathandiza kupereka kulumikizana kotetezeka komanso kokhazikika pakati pa makina ndi chingwe chomwe chalumikizidwa nacho.

Mu bukhuli, tikuthandizani kumvetsetsa bwino momwe ma cable glands amagwirira ntchito.
Tiyeni tiyambe.

Zingwe za Chingwe ndi Zingwe za Chingwe
Ma waya otchedwa cable glands amadziwika kuti 'makina olowera mawaya' omwe amagwiritsidwa ntchito limodzi ndi mawaya ndi mawaya a:

• makina odzichitira okha (monga deta, ma telecom, magetsi, magetsi)
• zamagetsi, zida ndi kuwongolera

Ntchito zazikulu za chingwe cha chingwe ndikugwiritsa ntchito ngati chida chotsekera ndi chotsirizira.
Zimateteza malo osungiramo zinthu ndi zida zamagetsi, kuphatikizapo kutumiza zinthu izi:

• Kutseka kwina kwa chilengedwe

Pamalo olowera chingwe, kusunga mulingo woteteza kulowa kwa chipindacho ndi zowonjezera zosiyanasiyana zoyenera zomwe zadzipereka kuchita izi

Ma waya a chingwe mu makina odzipangira okha

• Kusindikiza kwina

Pamalo a chingwe chofika pamalo obisika, ngati pakufunika chitetezo chambiri cholowera

• Mphamvu yogwira

Pa chingwe kuti zitsimikizire kuchuluka kokwanira kwa kukana kwa chingwe chamakina 'chokoka'

• Kupitiriza kwa dziko lapansi

Pankhani ya chingwe chotetezedwa, chingwe chikangopangidwa chimakhala ndi kapangidwe kachitsulo.
Zikatero, chingwe cha chingwe chingayesedwe kuti chitsimikizire kuti chikhoza kupirira mphamvu yokwanira ya peak short circuit fault current.

• Kuteteza chilengedwe

Kudzera mu kutseka chivundikiro chakunja cha chingwe, kupatula chinyezi ndi fumbi kuchokera ku chida kapena malo otchingira magetsi

Mwawona:
Zingwe zolumikizira chingwe zingapangidwe kuchokera ku zinthu zopanda chitsulo mpaka zitsulo.
Kapena zingakhale zosakaniza zonse ziwiri zomwe zingakhale zolimbana ndi dzimbiri.
Zimatsimikiziridwa ndi kusonkhanitsa motsatira muyezo, kapena ndi macheke osapsa ndi dzimbiri.

Ngati imagwiritsidwa ntchito m'malo ophulika nthawi zina, ndikofunikira kuti ma cable glands avomerezedwe mtundu wa chingwe chomwe mwasankha.
Ayeneranso kusunga mulingo wa chitetezo cha zida zomwe alumikizidwa nazo.

Chimodzi mwazinthu zabwino kwambiri zokhudza ma cable glands ndichakuti ali ndi ntchito ya IP68 yosalowa madzi.
Izi zikutanthauza kuti zingagwiritsidwe ntchito popanga malo otulukira osalowa madzi kuchokera m'malo ovuta komanso owopsa komanso kudzera m'malo otsetsereka.

Kuti muwagwiritse ntchito:
Chingwe cha chingwe chimakanikiza chisindikizo mu chingwe chozungulira.
Zimaletsa kulowa kwa tinthu tating'onoting'ono kapena madzi zomwe zingayambitse kuwonongeka kosatha kwa zipangizo zamagetsi.

Mwachitsanzo:
Ngati mukufuna kuyika chingwe pa malo obisalamo madzi, muyenera kuboola dzenje m'malo obisalamo.
Zimenezo zimapangitsa kuti zisalowenso m'madzi.

Zingwe zolumikizira chingwe pa mpanda wosalowa madzi
Kuti mukonze vuto lanu, mungagwiritse ntchito chingwe cholumikizira kuti chizitseke madzi kuzungulira chingwe chanu chomwe mukuchilowetsa m'chipinda chosungiramo zinthu.
Ntchito yosalowa madzi ya IP68 ndi yabwino kwambiri pa zingwe kuyambira mamilimita 3.5 mpaka 8 m'mimba mwake.
Mtundu uwu wa ma chingwe umapangidwira kuti uikidwe m'mbali mwa pulojekiti yosalowa madzi.
