Nws yog nyob rau hauv ib txoj kev uas txuas mus rau qhov chaw, nws yog ua li cas tso ntawm cables thiab nyob ntawm tej, thiab rau sab saum toj box yog them nrog ib tug hau, uas tuav qhov kev tso tawm latches. Ducts rau hluav taws xob thaiv siv standard "sticks" ntev ntawm 2 m. Tsis hais txog ntawm cov ntaub ntawv uas, qhov no tsim tsis txhawb combustion.

Nco ntsoov tias nyob rau hauv tas li ntawd mus rau ib tug yooj yim U-zoo li tus seem muaj ntau nyuab kev hloov kho nyob rau hauv daim ntawv ntawm "W". Ntawd ces yog los ntawm kev ua cov installation thawv rau xov thaum lub sij hawm installation yuav tsum tau muab faib mus rau hauv kab, muab lawv nyob rau hauv ib tug nyias muaj nyias ib seem ntawm ib tug tib tsim. Nyob rau hauv cov ntaub ntawv no, lub hau yuav tau muab cais.

Yuav ua li cas xaiv ib tug cable box

Feem ntau cov kev daws teeb meem yog pheej yig kev hloov kho ntawm yas. Nyob rau hauv tas li ntawd, muab piv nrog hlau, lawv yog yooj yim kom haum thaum lub sij hawm los ua ke. Box rau xov yas muaj lwm kom zoo dua - nyob rau hauv cov ntaub ntawv ntawm kev puas tsuaj rau lub cable rwb thaiv tsev txaus ntshai tej zaum yuav tsis tau mus kis tau ntau tshaj qhov saum npoo av. Thaum twg koj yuav nws yog ib qho tseem ceeb rau xaiv txoj cai tooj ntawm lub thawv. Feem ntau, pre-ntsuas yardage yuav tsum tau mus tshaj 10-20%, vim hais tias tsis muaj teeb meem yuav tshwm sim thaum uas lub mas yuav kis tau lub thawv yog tsis txaus thiab muaj qhov chaw mus nrhiav kev pab. Ntawm kev muag khoom muaj tseem yog nrog accessories: lem, ces kaum, tees, uas muab ib tug tiav lawm saib koj rooj vag. Cov ntsiab yuav tsum tau yuav kis tau. Yuav tsum tau tshwj xeeb mloog mus thaiv thawv nyob rau hauv lub tsob ntoo, vim hais tias thaum muaj tsis txaus ntawm tej kev tsim xaiv raws nraim tib yam nyob rau hauv lwm yam outlets yog yuav luag tsis yooj yim sua vim yog txawv nyob rau hauv cov xim tswvyim.

Ua ntej mus rau lub khw

Peb pom zoo kom siv cov nram qab no algorithm ntawm kev ua ntej mus rau lub tam sim ntawd purchase:

- xav txog qhov chaw installation ntawm nyob, keyboards, teeb thiab lwm yam kev pab, raws li zoo raws li lawv tus xov tooj;

- kos ib thaiv Circuit Court nyob rau thaj chaw;

- los mus txiav txim lub yuav tsum tau footage - mov yuav tsum tau;

- muab accessories (fab, sab hauv thiab sab nraud ntawm cov ces kaum, hlws ris thawv);

- coj mus rau hauv tus account lub luaj li cas ntawm cov thawv rau hluav taws xob thaiv thiab xaiv lub feem ntau haum, nyob ntawm seb lub hom cable siv; Nyob rau hauv tas li ntawd, qhov luaj li cas kuj muaj feem xyuam rau tus xov tooj ntawm khej nyob rau hauv cov khoom;

- los mus txiav txim yuav ua li cas nws yuav tsum tau nqa tawm nyob rau ntawm qhov chaw ntawm lub fixation, Tshuag li qhov tsim nyog cov cuab yeej;

- xav txog seb hlau thawv xav tau rau xov los yog yuav dispensed nrog yas versions. Ib tug meej ntxiv tais hlau - lawv lub zog. txawm lub high-voltage cable yuav pw nyob rau hauv lawv. Nws muab cov av hu. Box rau xov yas tseem tsis pub tso ib tug loj tus naj npawb ntawm cables thiab nyob ntawm tej, raws li yog pib sag, los yog yuav tsum tau ib yam nkaus thiab nquag txuas rau lub hauv paus.

Locks thiab cov ntaub ntawv

Tus thawj tuav lub hau tej zaum yuav muab tso nrog ob lub ob, thiab nrog rau ib txhais tes. Nyob rau hauv lub caij nyoog kawg no cov ntaub ntawv, es tsis txhob ntawm lub latch muaj ib tug tshwj xeeb zawj. Muab ob npaug rau mog fixation yog ntau txhim khu kev qha, ces nws yog qhov zoo tshaj plaws xaiv xws li ib tug qauv. "Kab Mob" ntawm tej yam manufacturers - insecure cover, vim hais tias ntawm yog dab tsi tsim nyog los npog me ntsis khob rau nws. Ntawm no, teeb meem pib: nyob rau hauv lub hnab yas yog feem ntau deformed duct (tawg ntho, khoov, thiab lwm yam ...). Yog li ntawd, thaum yuav yog qho tseem ceeb heev los ua kom kaw qhov xaiv qauv, thiab tsis los daws tau tej yam txawv kev pab raws qib thaum lub sij hawm installation. Piv txwv li, muaj mob thaum lub theem kawg ntawm tso lub hau ntawm lub ntsiab lus tsim nyog rau "nroj tsuag nyob rau hauv cov kua nplaum." Hlau ducts rau hluav taws xob thaiv nyob rau hauv no hwm yog zoo npaum li cas tshaj yas.

Qhov ntev

Cia peb xav txog dab tsi yog qhov thawv yas rau hluav taws xob thaiv. Lawv ntau thiab tsawg pab yog: 22 hli × 10 - 40 × 16 mm (conventionally xa mus rau raws li ib tug mini-raws); 12 hli × 7 - 16 × 12 hli (microchannels); 40 mm × 100 - 100 × 50 mm (feem ntau standard); 200 × 80 mm (loj loj). Muaj yog ib tug txheej txheem uas tso cai rau koj kom meej seb puas muaj tus tseeb loj. Ua li no, siv cov mis:

S = (N × D2) / K,

qhov twg S - rau yam ntoo khaub lig seem duct, mm.kv.; N - npaj tooj ntawm cable sau, pieces; d - lub cable txoj kab uas hla, hli; K - ib tug kho lus zoo tshaj, siv uas yog tsim nyog nyob rau hauv thiaj li yuav tiv thaiv kom txhob zawm dhau cov (0,45).

Tau soj ntsuam, koj yuav tsum xaiv lub tom ntej no lub thawv uas haum loj. By xaiv yas thawv rau hluav taws xob thaiv, uas yog tsawg tshaj li qhov yuav tsum tau qhov ntev (kev sib hais haum), nws yog ib qho tseem ceeb kom paub tias cov kub tswj cable tub ntxhais yog lawm thiab lub hau yuav nruj nreem yuav tsau thiab ya tawm yog hais tias ntawd kov rau qhov no tais.

installation tiav

Thaum ntsuas qhov xav sawb ntev mus ua ib lub cim, thiab lub thawv yog txiav los ntawm txoj kev ib tug handsaw rau hlau (tsis hais txog ntawm cov ntaub ntawv uas), cov riam mounting mob los yog sab cutters. Qhov no lub lag luam yuav tsum tau ua nyob rau hauv lub dho box muaj ib tug tais thiab ib tug kaw cover. Transition "phab ntsa-phab ntsa" thiab "phab ntsa-qab nthab" ua tau zoo dua nrog kev pab los ntawm tshwj xeeb ntawm cov ces kaum. Yog hais tias lawv ua tsis tau, nyob rau hauv tsis dhau ntug qhov chaw tej zaum kuj siv ib tug tshwj xeeb txoj kev: nyob rau hauv ib tug tais qoob loo paus, thiab nyob rau lwm yam - lub hau, thiab muab lawv. Txawm li cas los, txoj cai lub nyob rau hauv no txoj kev muaj peev xwm tau txais xwb nyob rau hauv cov ntaub ntawv ntawm puas-resistant cover khoom.

Nyob rau saum npoo, ib tug yooj yim mem hluav kos yog muaj yuav qhia tau rau yav tom ntej qhov chaw ntawm lub thawv. Pom zoo siv theem thiab plumb. Nyob rau hauv tus nto rau ntawm lub box tej zaum yuav glued siv kua rau tes, txawm li cas los, tsis muaj ntxiv lag luam yog tau tsuas yog tom qab ua tiav kom qhuav. Los ntawm cov ntoo phab ntsa tais yog ib qho yooj yim mus rau Mount nrog screws thiab ib tug cordless ntswj ntsia hlau. Cib thiab qhob bases yuav tsum tau ib tug txawv mus kom ze: lub hauv qab ntawm lub tais ua qhov (2-3 hli) txhua txhua 0.5 m box ntxiv muaj ntaub ntawv rau cov chaw ntaus cim theem rau ntawm phab ntsa thiab los ntawm qhov uas muab tso rau daim ntawv lo .. Lawv siv cov Impact Laum txiav txim los yog punch raws drilled rau dowels. Ntxiv los ua ke yog nyob rau hauv lub yas dhos nrog screws.

Nyob rau hauv hauv paus ntsiab lus, tsis muaj dab tsi nyuab txog txhim kho cable ducts tsis yog, thiab qhov no ua hauj lwm yog ua tau txawm rau ib tug inexperienced neeg. Qhov loj tshaj plaws - nws yuav tsis muaj nyob rau hauv ib tug hurry, tag nrho cov zoo zoo thiab xav hais tias vymeryat. Tshwj xeeb tshaj yog yog hais tias tus ua hauj lwm yog ua rau cov thawj lub sij hawm.

cables

Tej zaum nws yog heev yooj yim mus ua xws li ib tug yooj yim ua hauj lwm raws li tso cable lawv nyob rau hauv lub thawv. Kab bends "zmeitsya" nraub qaum ris rau hauv lub cover thiab li ntawd. Tshwj xeeb "naas ej" nyob rau hauv no hwm cables uas nws cores no yog ua los ntawm tawv ib conductors. Yog li ntawd, lawv yuav tsum tau ua tib zoo mus raws li lub thiab koov. Nyob rau hauv tas li ntawd, ib co thawv muaj ntxiv longitudinal partitions, simplifying tso ntawm xws "unruly" conductors. Qhov yooj yim txoj kev uas yuav mus txog ib zaug tag nrho cov kab thiab tsawg kawg yog pw nyob ze lub hau txhua dhau 'meter'. Yuav kom txo tau cov visibility ntawm cov pob qij txha yuav zoo siab txais tos peb tau piav saum toj no: pruning tais thiab hau, yog li ntawd tus kab tsis phim.

Pom zoo chaw kawm ntawv taw tes

SAE Handbook ua rau tsis muaj qhov yuav tsum tau rau qhov chaw ntawm nyob, keyboards, teeb thiab ib tug qauv ntawm cov tebchaws hauv lub cable sau. Txawm li cas los, txoj cai yog hais tias yuav lub unofficial lead kab ob horizontally thiab mas, tsis txhob curves. Nyob rau hauv cov ntaub ntawv ntawm dej ntws yaug nws yooj yim mus nrhiav tau cov kev raug mob rau ntawm qhov chaw, thaum lub txheej box zoo dua aesthetically pleasing. Qhov kev ncua deb ntawm lub qab nthab rau tus khiav yuav tsum 150 mm, thiab los ntawm cov qhov rai thiab lub qhov rooj qhib yog yuav tsum tau nyob rau hauv lub indentation 100 hli. Thiab, ntawm chav kawm, yuav kom muab cov intermediate hlws ris thawv nyob rau hauv kab mus rau pab zoo rau cov kab yog tias tsim nyog.

General tswv yim

Txij li thaum qhov kev ncua deb ntawm cov phab ntsa, qab nthab thiab hauv pem teb feem ntau txawv vim hais tias ntawm lub peculiarities ntawm lub domestic kev tsim kho, koj yuav tsum tsis txhob txiav lub cable box rau sab saum toj mounting, tshem cov kev ntsuam hauv qab no. Nyob rau hauv tas li ntawd, cov fab yuav tshwm sim ncaj nraim tsuas yog los ntawm sab nraum, tiam sis thaum koj sim mus nruab ib lub txoj ces kaum nws hloov tawm hais tias nws tsis yog. Next qhov lawv los ntawm cov phab ntsa, koj yuav tsum mus rau qhov chaw muaj cov raj (haum hlau thiab yas), yuav tsum tau mus hloov lub cheeb tsam los yog "prodernut" khiav. Tag nrho cov ntsiab lus yuav tsum tau muab coj mus rau hauv tus account.
