Ib daim duab tsim thiab ob tsab ntawv tsis meej pem tuaj yeem ua ntsiag to nce qhov project tus nqi los ntawm ntau pua txhiab tus yuan, thaum txoj kab kev nyab xeeb ntsiag to rov qab los ntawm cov npoo loj. Cov phooj ywg nyob rau hauv engineering yuav tsum tau harboring tib lo lus nug: Vim li cas plaub lub cim yooj yim "flame-retardant cable" ntawm daim duab tig mus rau hauv cov ntawv tsis meej pem xws li B1, B2, ZA, ZB, ZC ... thaum lawv ntaus lub khw? Dab tsi ntxiv, tus nqi sib txawv ntawm lawv tuaj yeem dav li ntau txoj kev. Puas yog nws txhais tau tias qhov muag tsis pom kev xaiv qhov kim tshaj plaws nrog cov ntawv nyob rau pem hauv ntej yog qhov kev nyab xeeb thawj koom ruam? Niaj hnub no, Zhejiang Zhongjing Cable yuav tsis dhuav koj nrog cov kev cai qhuav tab sis piav qhia cov ins thiab outs hauv cov lus dawb.
Qhov no tsis yog hais txog kev txhawb nqa koj kom ruam thiab txuag nyiaj, tab sis hais txog kev qhia koj yuav ua li cas faib txhua qhov peev nyiaj txiag rau qhov tseeb kev nyab xeeb. Ua ntej, cia peb rhuav tshem qhov kev xav tsis zoo: "B1 qib" thiab "ZB qib" tsis yog cov qhab nia los ntawm tib qhov kev xeem thiab tsis tuaj yeem muab piv raws li tus lej twg loj dua lossis tsab ntawv twg los ua ntej. Nws zoo li tus menyuam kawm ntawv uas tau 90 hauv Suav (qib B1) thiab 85 hauv lej (ZB qib). Koj puas tuaj yeem hais tias tus qhab nia Suav yog "siab dua" dua li tus lej lej? Kom meej meej tsis yog, vim hais tias lawv yog cov sib txawv kiag li kev kawm. Code "B1": Nws ntsuas qhov "kev phom sij hauv zej zog tom qab hluav taws kub". Nws yog raws li lub npe nrov GB 31247 lub teb chaws tus qauv. Code "ZB": Nws ntsuas qhov "tus kheej- tiv thaiv kub hnyiab". Nws yog raws li lwm lub teb chaws tus qauv, GB / T 19666. Qhov kev ntsuam xyuas no zoo ib yam li "kev sib tw hnyav heev".
Tus kws tshuaj xyuas nruj nreem bundles ib pawg ntawm cov cables zoo li cov taws tswm ciab thiab tom qab ntawd muab cov nplaim taws kub hnyiab rau qee lub sijhawm. Tom qab qhov kev ntsuam xyuas, tsuas yog ib cov ntaub ntawv yog ntsuas: deb npaum li cas cov nplaim taws tau nce mus txog lub nra ntawm cables (kev tshaj lij hu ua "carbonization qhov siab"). Raws li qhov kev sib kis no, cov qib endurance tau txiav txim siab: qhov muaj zog tshaj plaws yog qib ZA, zoo yog qib ZB, passable yog qib ZC, thiab qhov tsis muaj zog tshaj yog qib ZD. Qib ZB sawv cev rau "tus tub kawm kev ua siab ntev" ntawm no. Nws qhia tau hais tias cov pob khoom ntawm cov cables no tuaj yeem tswj tau qhov hluav taws kub thaum muaj hluav taws kub hnyiab thiab tiv thaiv cov nplaim taws los ntawm kev sib kis sai sai raws li cov kab hluav taws xob zoo li "parkour". Nws tsom mus rau qhov tseem ceeb ntawm kev ua tau zoo ntawm lub cable tus kheej tiv thaiv cov nplaim taws.
Txhawm rau muab nws yooj yim dua: Ib pob ntawm cov kab ntawv pov thawj raws li qib ZB tej zaum yuav "siab tawv" hauv cov nplaim taws thiab nyuaj rau ignite. Txawm li cas los xij, yog tias cov ntaub ntawv rwb thaiv tsev thiab cov ntaub qhwv siv hauv nws qhov kev tsim khoom tsis zoo, ib zaug ignited los ntawm qhov kub thiab txias, nws tuaj yeem tso tawm ntau qhov tuab, choking cov pa luam yeeb dub, dhau los ua "tus neeg tua neeg tsis pom" hauv qhov hluav taws kub. Ntawm qhov tod tes, ib pob ntawm B1 qib cables yog "zoo- cov tub ntxhais kawm sib npaug" los ntawm "nyuaj rau ignite" mus rau "txawm tias kub hnyiab, qhov phom sij yog tswj tau". Tam sim no koj nkag siab tias cov no yog ob qho tib si kev ntsuas kev sib txuas, ib qho saib tag nrho cov kev phom sij thiab lwm qhov ntawm cov nplaim hluav taws kub tshwj xeeb. Lawv txhawb ib leeg tab sis tsis tuaj yeem hloov ib leeg. Vim tias ob lub tshuab no tau koom ua ke hauv kev ua lag luam rau lub sijhawm ntev, qee qhov txawv txav "hybrid" qauv tau tshwm sim, feem ntau yog "WDZB1-YJY" tau hais thaum pib.
Kuv twv hais tias koj tau pom nws muaj nyob rau hauv ntau qhov project drawings lossis procurement lists. Tab sis hmoov tsis, nyob rau hauv lub officially prescribed naming txoj cai rau cable qauv nyob rau hauv lub teb chaws tus qauv, tsis muaj qhov chaw rau lub cim "B1"! Qhov kev sau ntawv no yog ib qho xwm txheej ntawm lub tswv yim tsis meej pem thiab yog ib qho kev qhia tsis zoo thiab tsis ua haujlwm. Txoj hauv kev kom raug yuav tsum yog ob txoj kab meej: Cable qauv: Kom meej meej sau WDZA, WDZB, WDZC, thiab lwm yam. Nplaim taws retardancy qib: Nws yuav tsum raug sau tseg tias nws cov nplaim hluav taws xob ua raws li Qib B1 (los yog Qib A, Qib B2) ntawm GB 31247 tus qauv. Yog li, lwm zaus koj tuaj hla cov ntawv tsis meej pem xws li "WDZB1", koj yuav tsum tam sim ntawd tsa tus chij liab hauv koj lub siab: txawm tus tsim qauv lawv tus kheej tsis meej pem thiab tau sib xyaw ob lub tshuab, lossis koj yuav tsum tau saib xyuas cov chaw tsim khoom thiab nug lawv kom meej: Puas yog cov cable no tau lees paub rau ZB-cov nplaim hluav taws kub hnyiab lossis tau txais B1-level nplaim hluav taws xob? Tus nqi thiab kev nyab xeeb ntawm ob qho no yuav txawv heev.
Tau nkag siab cov ntsiab lus, koj yuav tsum xaiv li cas hauv kev siv tswv yim? Nco ntsoov ib lub hauv paus ntsiab lus tseem ceeb: ua ntej, saib cov txheej txheem yuav tsum tau ua; thib ob, xav txog tej yam txaus ntshai ntawm qhov scenario; thiab thaum kawg, ua qhov kev ntsuam xyuas dav dav ntawm cov peev nyiaj. Thaum tib neeg lub neej nyob ntawm ceg txheem ntseeg, B1- theem (thiab feem ntau yog halogen-dawb thiab haus luam yeeb WD) yuav tsum tau siv. Hauv cov cheeb tsam no, cov kev cai tau meej meej thiab tsis muaj chaw rau kev sib tham:
Cov chaw khiav tawm tsis yooj yim: cov tsev kho mob hauv tsev kho mob, cov tsev laus, cov tsev laus, cov chaw ua kis las loj, xinesmas, ua yeeb yam, thiab lwm qhov chaw uas muaj neeg coob coob. Cia li xav txog tej yam, yog tias txoj kev khiav tawm muaj cov pa luam yeeb muaj kuab lom, qhov tshwm sim yuav yog qhov xav tsis thoob.
Cov chaw thauj mus los loj: cov chaw nres tsheb hauv subway, siab - chaw nres tsheb ciav hlau ceev, tshav dav hlau terminals, thiab cov kev lag luam hauv av ntev. Cov chaw no muaj neeg coob coob, muaj cov txheej txheem nyuaj, thiab ntsib kev khiav tawm ntau heev.
Cov pa luam yeeb thiab plua plav- qhov chaw nkag siab: cov chav hauv computer tseem ceeb ntawm cov chaw khaws ntaub ntawv, cov chaw sib txuas lus tseem ceeb. Ntawm no, cov cuab yeej siv hluav taws xob kim kim yuav ua rau muaj pa taws thiab plua plav ntau dua li tib neeg. Ob peb wisps ntawm cov pa luam yeeb tuaj yeem ua rau lub cev tsis ua haujlwm, ua rau poob ntau lab.
Kev xaiv logic: Hauv cov xwm txheej no, cov neeg tua neeg tseem ceeb hauv hluav taws feem ntau tsis yog cov nplaim taws lawv tus kheej, tab sis cov pa luam yeeb sai sai thiab cov pa phem. Tus nqi tseem ceeb ntawm B1-theem cables nyob rau hauv qhov txo qis ntawm cov pa luam yeeb tuag nyob rau hauv qhov tseem ceeb thawj ob peb feeb ntawm hluav taws, muab "lub kaus tiv thaiv" rau lub neej thiab cov khoom siv tseem ceeb.
Kev nkag siab txog qhov sib txawv ntawm kev nyab xeeb logics tom qab cov qauv yog qhov tseem ceeb tshaj qhov tsuas yog nco ob peb qib ntawv. Kev tawm tsam lub luag haujlwm thiab tus nqi ntau tshaj - qhov zoo sib npaug ntawm txoj kab liab kev nyab xeeb thiab cov kev xav tau ntawm tus nqi - qhov no, tej zaum, yog tus nqi tiag tiag uas peb txhua tus, raws li cov kws tshaj lij engineering, tsim tshaj li cov qauv tsim thiab cov hlau.
