M'mafakitale omwe muli mpweya woyaka, nthunzi, kapena fumbi, kugwiritsa ntchito zida zoteteza kuphulika ndikofunikira kwambiri. Chimodzi mwazinthu zofunika kwambiri pakuwonetsetsa chitetezo ndi chingwe chosaphulika. Monga wopanga zingwe zolumikizira chingwe ndi chitetezo, Weyer amapereka mitundu yosiyanasiyana ya chingwe chopanda kuphulika chomwe chimapangidwa kuti chikwaniritse miyezo yolimba yachitetezo ndikupereka magwiridwe antchito odalirika m'malo owopsa.
Malinga ndizakuthupi, kuphulika-umboni chingwe glands akhoza kugawidwa mu pulasitiki (polyamide) ndi zitsulo (nickel-yokutidwa mkuwa / chitsulo chosapanga dzimbiri 304/316). Pulasitiki imodzi ikufanana ndi nambala yachitsanzo:Chithunzi cha HSK-EX. Chitsulo chimodzi chikufanana ndi nambala yachitsanzo:Chithunzi cha HSM-EX. Ulusi wa Metric/Pg/Npt/G ulipo.
Malinga ndidigiri yotsimikizira kuphulika, pali mitundu ya Ex e ndi Ex d. Ex e ndi kuchuluka kwa chitetezo chamtundu, chifukwa mkati mwawokha sichitulutsa kutentha koopsa, arc ndi spark kuthekera, kotero palibe flange. Ex d ndi mtundu wamoto. Chifukwa iyenera kupirira kuphulika kwa mkati, iyenera kupangidwira njira yotulutsira mphamvu (yotchedwa flange). Chifukwa chake makulidwe ake apakati a chipolopolocho ndiambiri kuposa kuchuluka kwa chitetezo. Ex e ikufanana ndi nambala ya gawo:Chithunzi cha HSM-EX. Weyer Cable Glands zomwe zimagwirizana ndi Ex d standard ndiZithunzi za HSM-EX1-4.
Malinga ndintchito, Ex d cable gland imagawidwa kuti ikhale ya zingwe zankhondo kapena ayi. Weyerkupanikizana kawiri HSM-EX1ndichisindikizo chimodzi HSM-EX3ndi za zingwe zopanda zida, ndi zitsanzokupanikizana kawiri HSM-EX2ndiHSM-EX4 yosindikizidwa kamodzindi za zingwe zankhondo. Ma glands a zingwe zokhala ndi zida amapereka chitetezo chowonjezera ku zovuta zamakina ndi zinthu zachilengedwe. Ndizofunikira m'mafakitale monga mafuta ndi gasi, pomwe zida nthawi zambiri zimakhala zovuta.
Zingwe zama chingwe za Weyer zosaphulika zonse zidayesa mayeso okhwima ndipo zili ndi ziphaso za RoHS, ATEX ndi IECEx. Takulandirani kudina bokosi la zokambirana ndikusiya zosowa zanu. Wogulitsa wathu adzakulumikizani posachedwa kuti akulimbikitseni chitsanzo choyenera kapena kukutumizirani zambiri.
