Kev ua tau zoo yog qhov ntsuas ntawm qhov ua tau zoo thiab raug ntsuas hauv kev lag luam hluav taws xob hluav taws xob siv ntau yam qauv hauv tebchaws lossis thoob ntiaj teb xws li ANSI, IEEE, IEC, ASTM, thiab lwm yam. Thaum ua tiav cov qauv no yog qhov tseem ceeb, feem ntau tau los paub txog cov qauv no cov hnub tau tuaj sawv cev tsuas yog qhov xav tau tsawg kawg nkaus hauv ib daim ntawv thov. Vim li no, tuam ntxhab raws li cov neeg siv tau saib xyuas qhov sib txawv ntxiv cov khoom zoo uas siv cov kev ua tiav tshwj xeeb. Cov khoom zoo kuj yog txog kev tsim khoom. Hauv qhov no, cov qauv thiab cov txheej txheem txuas ntxiv txhim kho tsom rau kev tswj hwm thiab kev rov ua tau dua nrog lub hom phiaj ntawm xoom tsis xws luag. Thaum kawg, qhov zoo tau sawv cev ntawm cov khoom muaj peev xwm thiab lub neej ntev ntxiv rau kev ua raws li cov qauv yooj yim thiab cov neeg siv khoom tshwj xeeb.
Qhov kev hloov kho no rau INMR los ntawm Edward Niedospial, Tus Thawj Coj Tus Thawj Coj – Hloov Chaw ntawm MacLean Power Systems sib tham txog cov ntsiab lus no thaum nws los txog rau kev tsim cov tshuab hluav taws xob ua los ntawm cov iav toughened.
Kev tsim cov iav toughened insulators tuaj yeem raug suav hais tias yog suav nrog ntawm ob kauj ruam tseem ceeb: kev tsim ua lub plhaub iav; thiab tom qab ntawd sib dhos ntawm cov hlau fittings mus rau lub plhaub ntawd. Kev tsim khoom yuav tsum muaj cov khoom siv tshwj xeeb thiab tsuas yog qee tus tsim cov khoom siv thoob ntiaj teb muaj cov khoom siv thiab kev paub dhau los ua ob kauj ruam hauv ib qho chaw ntau lawm. Hauv qhov no, nws yog qhov zoo rau kev kawm zoo tsis tsuas yog nws cuam tshuam txog kev tsim khoom ntawm lub ntsej muag iav toughened tab sis kuj tom qab thaum lub sijhawm sib dhos kawg ntawm cov kab thaiv dej.
Daim duab 1: Txiav-tawm ntawm lub iav iav toughened qhia tau plhaub, cap& tus pin, xis mas
Lub ntsej muag iav plhaw muaj lub ntsej muag tiag tiag insulator. Thaum lub rooj sib dhos haum thiab nws cov cementing tseem ceeb ib yam nkaus, lub plhaub no yuav tsum nyob twj ywm hauv lub neej tag nrho cov kev pabcuam kom paub tseeb tias cov khoom ua haujlwm. Ntxiv mus, ib zaug sib sau ua ke, kev tshwm sim ntawm lub plhaub tawg tsis yog tshwm sim los ntawm qee qhov xwm txheej sab nraud yuav tsum tsis tshua muaj tshwm sim. Piv txwv li, kev cia siab ntawm kev lag luam dav dav yog tias tsawg dua 1 tauj 10,000 qhov chaw nruab rau ib xyoos yuav tsum tau tawg ua ntaws. Xws li, qhov tshwm sim ntawm tus kheej tawg yog ib qho ntawm kev tsim kev lag luam uas lub Hoobkas yuav tsum sib zog ua kom tsawg.
Sib nrug los ntawm lub plhaub tseem ceeb, cov khoom kho vajtse ntawm cov iav uas muaj lub zog tawv iav muaj xws li:
1. Caps
Lub hau rau saum yog hlau ductile haum uas tau raug galvanized thiab sib sau nrog lub taub hau stainless-hlau txhav tas.
2. Cov pins
Hauv qab pin haum yog lub forged steel pob txuas uas tau raug galvanized thiab coated nrog bituminous tar. Tsho hluav taws xob zinc dab tshos tuaj yeem muab ntxiv rau qhov kev ua kom ntev, tshwj xeeb tshaj yog hauv cov kev pabcuam loj.
Clevis / tus nplaig fittings qee zaum siv thaum qis qis.
