Tshuab rau cov vov tsev ntawv
Cov khoom ua ke ntawm cov khoom siv pobzeb tsim los ntawm tshuab rau cov vov tsev tsis muaj cov kua qaub, alkalis thiab ntsev. Hauv kev siv mus sij hawm ntev, nws tsis muaj qhov tsis muaj xeb, yog li cov khoom muaj peev xwm tswj tau lub cev zoo. Kev siv cov khoom ua tau zoo ntawm PVC cob ua cov khoom siv dag, ntxiv rau UV ultraviolet nqus, tshuaj tiv thaiv kab mob, hloov kho, thiab lwm yam, kom paub meej cov kev pab lub neej ntawm cov khoom. Txawm hais tias raug rau ultraviolet, av noo, cua sov, txias thiab lwm yam puag ncig rau lub sijhawm ntev, nws tseem tuaj yeem tswj nws qhov kev ruaj khov thiab ua kom lub sijhawm ntev siv kom muaj kev nyab xeeb ntawm cov khoom. Siv cov thev naus laus zis ob-txheej kev lag luam hauv kev lag luam, nws muaj cov khoom siv zog dua thiab kev ua tau zoo dua li ib leeg-txheej pobzeb. Kev ntsuam xyuas los ntawm Lub Chaw Kuaj Tshuaj Tebchaws Tshuaj pom tau tias 1.2m purlin spacing nce 1500N, kev hloov pauv ntawm cov yas pob zeb qis dua li 3% tau raug tshuaj xyuas los ntawm Lub Chaw Kuaj Tshuaj Tshuaj Hauv Tebchaws, thiab qhov ntsuas hluav taws kev ua haujlwm yog nplaim hluavtaws B1, txhua qhov hais txog txoj kev nyab xeeb hluav taws Cov. Txhua lub tuam tsev cov qauv tsim nyog rau kev nyab xeeb thiab kev tiv thaiv ib puag ncig cov ntaub ntawv vov tsev pom zoo los ntawm National Association rau Lub Tsev Txhawb Kev Txhawb Nqa Cov Khoom Siv. Lub thermal conductivity ntawm cov nplais tsim los ntawm PVC ru tsev cov khoom siv pobzeb yog 0.22, li 1/3 ntawm cov nplais pob zeb thiab 1/2000 ntawm 0.5 hli tuab xim xim pobzeb. Yog li, tsis muaj txheej txheem rwb thaiv tsev kub thiab cua txias, kev ua haujlwm thermal rwb thaiv tsev ntawm cov nplais tsim los ntawm PVC ru tsev cov khoom siv pobzeb pob zeb tseem tuaj yeem ncav tau qhov zoo tshaj plaws thiab ua tau raws li qhov kev thov. Cov nplais tsim los ntawm PVC vov tsev cov khoom siv pobzeb cov cuab yeej tuaj yeem tiv thaiv lub suab nrov uas tsim los ntawm cov xwm txheej ntuj xws li dej nag thiab cua.
Cov vuas tsim tshuab rau cov vov vov ntawv yuav tsum tsis txhob cuam tshuam ncaj qha hauv cov khoom siv rwb thaiv tsev thermal. Kev tsim kho kev nyab xeeb, txhawm rau ua kom muaj kev nyab xeeb ntawm tus kheej, tus ntaiv lossis lwm qhov chaw tsim nyog yuav tsum tau siv hauv kev tsim kho. Thaum lub sijhawm teeb tsa, koj tsis tuaj yeem ua ntu nruab nrab ntawm ob lub hnab tawv me. Ua haujlwm rau kev ua haujlwm tsis haum rau qhov ntsuas kub hauv qab - 5 C thiab huab cua ntub xws li nag thiab daus. Kev tsim qauv tsim, PVC ru tsev pobzeb khoom tsim pobzeb ntau lawm, phab ntsa vaj huam sib luag series, tsis tshem tawm thiab qab nthab series siv rau lub ru tsev truss qhov siab-qhov nruab nrab ntawm 1: 5-1: 6, txhua nplais yuav tsum nruj me ntsis raws li qhov yuav tsum tau ua ntawm purlin spacing kev tsim kho. Hauv kev tsim kho, ob lub yoj vias, vuas vuas vov, phab ntsa daim duab, tsis rhuav tshem thiab qab nthab series yog sib tshooj nrog ib nthwv dej, thiab qhov sib tshooj ntev ntev (sib tshooj ntawm qhov ntev) yuav tsum tsis pub tsawg dua 100 ko taw. Tsau vuas vov tsev, phab ntsa vaj huam sib luag, tshem tawm-dawb thiab qab nthab koob tuaj yeem kho tau los ntawm cov kws tshaj lij hooks muab los ntawm peb lub tuam txhab, lossis los ntawm kev siv tus kheej. Cov kab ntawm cov vuas tsim los ntawm PVC vov tsev cov khoom siv pobzeb pob zeb yuav tsum tau kho los ntawm kev hooks muab los ntawm peb lub tuam txhab. Nws tsis raug tso cai los ntxuav purlin tsau los ntawm cov ntoo tshwj xeeb ntsia hlau muab los ntawm peb lub tuam txhab.
Ob txheej khoom fittings yuav tsum tau nruab ib qho kom haum rau txhua qhov purlin thiab cov nplais, thiab cov fittings yuav tsum tau tsau rau ntawm cov kab nrhuam. Qhov ntsug ntug ntawm cov pobzeb tsim los ntawm PVC vov cov vuas vov cov khoom siv yuav tsum tau tsau rau purlin nrog fittings ntawm txhua nthwv dej ncov. Kev txhawb nqa kev tiv thaiv yuav tsum ntsuas hauv qhov chaw muaj cua hlob heev. Thaum txhim kho phab ntsa vaj huam sib luag, ntau tshaj li ob lub rivets yuav tsum siv los kho txhua purlin ntawm sib tshooj ntawm ob phab ntsa ntsa. Thaum txhim kho cov nplais nuv, yuav tsum siv cov roj hmab tshwj xeeb hauv qab cov nplais, thiab cov txiv ntoo yuav tsum tau muab daws kom haum, tsis txhob nruj dhau. Thaum txhim kho lub ru tsev vov, ob sab ntawm cov nplais thiab cov pobzeb pobzeb yuav tsum tau nruab tib lub sijhawm. Thaum txiav cov nplais, siv cov xov txhuam hniav to taub pom. Cov txheej txheem teeb tsa ntawm kev txhim kho pob zeb ci ntsa iab zoo ib yam li saum toj no. Txhua daim ntaub thaiv uas ci ntsa iab yuav tsum muaj kev sib cais ntawm qhov zoo thiab qhov tsis zoo ntawm siv. Thov nruab los ntawm pawg kws tshaj lij txhawm rau txhim kho kev ua haujlwm zoo.
Cov Lus Cim Txheej Txheem:
Lub purlin tuaj yeem ua cov square yeeb (60 * 40 * 3mm) lossis C-seem steel (100 * 50 * 20 * 3mm) lossis anti-corrosion ntoo square (60 * 40mm). Lub purlin spacing yog 660 hli, npaj txij hauv qab mus rau sab saum toj. Cov nplais loj yuav tsum tau muab ntsia rau hauv qhov kev hloov rov qab mus raws li kev qhia hauv zos. Ib vuag watt yog lapped thiab nqa tawm ib txhij ntawm ob tog. Thaum txhim kho lub voos caj dab zoo, txiav ib ntu ntawm thawj lub pobzeb pob zeb ua ntej yuav txhim kho nws. Kev sib tshooj ntawm txoj cai thiab inclined caj vuas yuav tsum tau saw ua ke. Tom qab kev teeb tsa ntawm txoj cai thiab inclines Rauv vuas tiav, peb-txoj kev vuas yuav tsum muab ntsia. Cov txhim kho yog cov fittings tshwj xeeb. Tsau nrog cov laum hluav taws xob, lub qhov taub yog 2 hli loj dua ntawm cov ntsia hlau ntsia hlau ntsia hlau.
Txoj kab uas hla ntawm tapping ntsia hlau yog 6.3 hli. Cov txheej txheem teeb tsa ntawm cov nplais pob zeb yog tib yam li ntawm cov xim pobzeb steel. Qhov tseeb, tsuav yog cov neeg ua haujlwm tsim cov xeb lossis cov hlau ua tsis zoo los qhia. Txoj kev teeb tsa yog yooj yim thiab ceev.
Cov yam ntxwv ntawm cov nplais hluavtaws hluavtaws:
Xim tsis kam: lub tshuab rau lub ru tsev ntawv saum npoo Cov khoom siv saum npoo ntawm cov nplais hluavtaws yog ua los ntawm kev txua cov khoom ntoo engineering nrog super weatherability. Nws muaj super durability nyob rau hauv ib puag ncig ntuj. Nws tuaj yeem tswj nws cov xim ruaj khov txawm hais tias nws raug rau ultraviolet hluav taws xob, av noo, cua sov thiab txias rau lub sijhawm ntev.
Cov kabmob muaj peev xwm zoo: hluavtaws cov nplais nplaum tau muaj cov kabmob zoo. Hauv thaj chaw tsis kub, txawm tias lub ru tsev npog nrog daus tag nrho cov xyoo puag ncig, cov nplais ntawm cov nplaim hluavtaws yuav tsis ua rau puas thiab puas. Kev ntsuam xyuas pom tias nyob hauv qhov xwm txheej ntawm 660 hli txhawb kev nrug thiab 150 kg thauj khoom, pobzeb yuav tsis tsim kom tawg thiab puas tsuaj.
Lub suab rwb thaiv tsev zoo yog qhov zoo: Qhov kev ntsuam xyuas ua pov thawj tias cov nplais yas pob zeb muaj lub suab zoo suab nrov thaum nws cuam tshuam los ntawm cov suab nrov sab nraud xws li nag thiab gale.
Poob siab tsis kam, zoo kub tsis kam: cob hluavtaws pobzeb muaj muaj zog sab nraud bearing. Qhov kev poob dawb ntawm 1 kg steel npas los ntawm 3 m qhov siab yuav tsis ua rau tawg, thiab qhov cuam tshuam ntawm qhov kub tsawg yog qhov zoo tshaj.
