Cable allergic: lub hom phiaj, qauv, hom

Nyob rau hauv raws li qhov hluav taws kub kev nyab xeeb uas yuav tsum tau rau tso tej kev sib txuas lus yuav tsum ua lub tsev cable penetrations - cov khoom, prefabricated siv, uas yog npaj rau cov zaj uas lub cables, pipelines, kev sib txuas lus kab los ntawm cov phab ntsa thiab partitions. Lawv lub ntsiab lub hom phiaj - kom tsis txhob kis rau hauv hluav taws uas nyob ib sab chav rau cov ntaub ntawv. Lawv nyob rau lub hauv paus ntawm tus txha venture 2.13130.2009 thiab GOST R 53310-2009. Lawv installation yog yuav tsum tau thiab tswj los ntawm tsoom fwv teb chaws txoj cai lij choj.

Hluav Taws compartments thiab cable penetrations

Raws li qhov hluav taws kub kev nyab xeeb uas yuav tsum tau nyob rau hauv kev tsim kho ntawm lub tsev vaj tse ntawm cov vaj tse, lawv muab faib ua hluav taws compartments uas thaiv nyob rau hauv nws lub teb chaws nrog hluav taws thiab pa taws, tsis txhob muab lawv mus rau kis tshaj lub compartment. Txawm li cas los nyob rau hauv tej chav tsev kuaj engineering kab uas ua txhaum lub meej mom ntawm qhov hluav taws kub sealing seem. Nyob rau hauv thiaj li yuav kom cov hluav taws kub ib thaj tsam thiab lug mounted cable penetrations.

Ib tug piv txwv uas qhia tau lub tseem ceeb ntawm installation ntawm xws lug yog ib tug tua hluav taws nyob Ostankino ntauwd nyob rau hauv 2000 xyoo. Ntawm no telecommunication kab twb muab tso rau hauv ib ntsug ncej, yog tsis compartmentalized rau hauv hluav taws compartments thiab pw ntawm kev tiv thaiv dhau mus. Raws li ib tug tshwm sim, qhov hluav taws kub kis toj kis thoob plaws lub tsev.

Tus tsim ntawm cable penetrations

Qhov yooj yim yog ib tug hlau cable allergic tes tsho nyob ruaj nrees hauv ib lub phab ntsa los yog muab faib. Lub tes tsho kis tau los ntawm cov cable, lub conduit, sab kab uas hla ntawm uas yog me ntsis me me tshaj lub cheeb ntawm hluav taws tsim. Cov kis ntawm cov kev sib txuas lus txoj kab thiab lub puab phab ntsa ntawm lub liner sau cab, kom huv si impregnated nrog roj. Uas yog vim li cas tej yam yooj yim cable penetrations tseem hu ua qog. Tsis tas li ntawd, es tsis txhob los yog raws cab tej zaum yuav siv asbestos, roj hmab rings, tshwj xeeb cov.

Thaum muaj chaw thiab lub hwj chim nroj tsuag yog nyob rau ob peb lwm designs. Lawv sawv cev rau lub ob hlau ib daim hlab, qhov xaus ntawm uas yog kev cob cog rua rau lub tes tsho. Yuav kom muab cov kis ntawm tus kev sib txuas lus thiab lub puab phab ntsa ntawm lub aperture thiab siv tshwj xeeb txuas. Ib tug xws li cable allergic yog siv los hla ib tug ob peb kab ntawm engineering.

Ntaub ntawv rau kev sib khi

Yuav kom tsim tau tso ib tug ntxiv los yog kev hloov ntawm cov laus txoj kab ntawm engineering tag nrho cov nyob ntawm tej, cables thiab lwm yam kev sib txuas lus dhau los ntawm phab ntsa nyob rau hauv thawv los yog scraps ntawm hlau hlab (tsho). Yog li ntawd, lub sealing ntawm cable penetrations yuav tsum tau ua los ntawm ib tug refractory, water- thiab roj-ceev cov ntaub ntawv uas yog yooj yim muab tshem tawm.

Nyob rau hauv cov ntaub ntawv no, muaj peev xwm tiv thaiv hluav taws nyob rau kev txiav yuav tsum tsis txhob yuav tsawg tshaj li lub peev xwm ntawm refractory phab ntsa.

Lub SNP 3.05.06-85 qhia txog sib tov uas yog tso cai rau sau ib kis ntawm tus cable thiab lub sinking:

• MAAs-xuab zeb sib tov nyob rau hauv ib qho ratio ntawm 1:10;
• muaj pes tsawg leeg ntawm av nplaum thiab xuab zeb ntaub ntawv piv 1: 3;
• sealing luj ntawm av nplaum, xuab zeb thiab xis mas (1.5: 11: 1);
• plaster, txhab perlite, noj nyob rau hauv tus piv 2: 1;
• lwm yam ntaub ntawv uas hais tias tau uas yuav tsum tau ntawm cov hluav taws kev ruaj ntseg.

Ntsaws lub cable allergic yog tseem tso cai siv ua npuas ncauj, yog hais tias nws yog ntawv pov thawj nyob rau hauv raws li cov uas yuav tsum tau ntawm GOST R 53310-2009. Qhov khoob nyob rau hauv lub phab ntsa yuav tsum tshuav dab tsi yog tias tus phab ntsa yog tsis hluav taws teeb meem.

modular allergic

Nyob rau hauv hnub no tus siv kev lag luam rau rwb thaiv tsev ntawm hluav taws compartments siv modular allergic. Lawv sawv cev rau ib tug steel los yog yas ncej, uas yog nruab nrog cov dig muag inserts los yog modules nrog qhov. Yuav kom tiv thaiv electromagnetic tawg txheej tooj liab gaskets. Ceev ceev yog tsim nro bolts.

Nyob rau hauv dav dav, lub modular cable penetrations hluav taws yog nyuab siv, tuaj txoos ua ke rau ntawm qhov chaw los ntawm prefabricated sealing inserts ntawm hard polymer amenable mus combustion. Raws li siv fastenings ntsiab ua los ntawm galvanized steel hlau.

Nyob rau hauv xws li ib tug drifting cable fits rau hauv ib tug tshwj xeeb kev sib khi module thiab enhanced ceev ceev crimped adapter. Nrog nro screws screwing sealing insert yog compressed nruj nreem crimped cable thiab muab ib cov roj thiab dej kuj allergic.

Nta installation ntawm cable penetrations

Mounting penetrations nws muaj nws tus yam ntxwv, uas nyob ntawm seb cov ntaub ntawv uas yuav txhawb tau cov qauv. Yog li, tso cable tshuab rau hauv lub tsev pob zeb ua vaj tse, hluav taws kub retardant Siv raug nteg ncaj qha nyob rau hauv lub formwork ua ntej pouring lub pob zeb mix. Nyob rau hauv kev tsim kho ntawm vaj tse prefabricated tsev hom allergic nyob rau hauv lub blocks yog pw nyob rau hauv lub Hoobkas thaum lub sij hawm siv thiab ua.

Nyob rau hauv lub tsev ntawm bricks rau qhov kev siv ntawm cable tshuab yog muab tso rau hauv tshwj xeeb ducts - Stroebe. Nyob rau hauv lub npaj txhij-monolithic vaj tse pob zeb diamond laum tho qhov me me. Cov kab uas hla ntawm lub allergic li xam nyias. Thaum lub sij hawm tsim kho los yog lub lag luam ntawm lub ntus allergic ntawm lub tsev yog ua los ntawm tshwj xeeb hluav taws retardant tog hauv ncoo.

Test cable penetrations

Nyob ntawm qhov chaw uas cov kev khiav hauj lwm cable penetrations yuav tsum tau raws li cov uas yuav tsum tau. Yog li ntawd, thaum lawv tso lub nuclear fais fab nroj tsuag yuav tsum tau soj ntsuam kuaj rau cov muaj peev xwm mus nqus, cais tawm los yog muaj kev cuam tshuam tawg.

Nyob rau pa siv qhov chaw Universal Cable allergic yog soj ntsuam los ntawm tshav kub, quab yuam kev ua (mas nyob rau hauv dabtsi yog khoov kuj), raws li zoo li hluav taws, dej thiab nkev-barrier zog.
