Ntoo cable drums muaj ob ntu: ob lub flanges puag ncig txuas rau lub thoob nruab nrab. Raws li lub npe qhia, lawv yog ua los ntawm ntoo.
Ntoo cable nruas yog siv tsis tu ncua rau winding, thauj, thiab tiv thaiv kev lag luam cables. Flange qhov ntau thiab tsawg sib txawv ntawm 30cm mus rau 3m, nrog qee qhov tshwj xeeb nruas ntau yam raws li cov kev xav tau tshwj xeeb. Raws li cov khoom siv, ntoo cable nruas tuaj yeem muab faib ua plywood cable drums, ntoo cable drums, thiab qee yam khoom ntawm steel-wood hybrid cable drums. Lub sij hawm lub sij hawm "ntoo cable nruas" feem ntau yog hais txog ruaj khov ntoo cable nruas.
Cov specs ntawm ntoo cable nruas yog txiav txim siab los ntawm kev siv ob peb yam:
1. Flange txoj kab uas hla (mm)
2. Flange thickness (mm)
3. Lub taub hau taub (mm)
4.Inner dav (qhov deb ntawm flanges)
Nrog rau cov ntaub ntawv no, lub chaw tsim khoom yuav kos duab raws li cov kev xav tau tshwj xeeb, suav nrog ntau yam tsim nyog thiab txoj kab uas hla ntawm bolts los muab cov khoom siv lub zog, thiab hloov cov ntawv txhawb nqa thiab cov nplhaib txhawb nqa. Lub thickness ntawm lub phaj phaj yuav ntxiv tau kho kom tau raws li qhov yuav tsum tau load-cov kabmob muaj peev xwm.
Ntoo cable nruas muaj cov qauv yooj yim, txawm li cas los xij kom ua tau raws li cov qauv xa tawm, ntau yam yuav tsum tau ua ua ntej yuav tsum tau ua.
1. Cov ntaub ntawv noo noo ntawm cov khoom ntoo yuav tsum muaj tsawg dua 20%, ua cov ntaub ziab khaub ncaws yog ib qho tseem ceeb rau kev ua kom cov pwm tuaj pwm rau lub sijhawm thauj.
2.The IPPC trendy yog ib qho xwm txheej tseem ceeb rau kev xa tawm cov khoom ntoo. Lub ISPM15 thwj rau ntawm ntoo qhia tias cov khoom tau dhau los ntawm kev kho fumigation, thiab kev lis kev cai yuav teeb meem cov ntaub ntawv fumigation rau kev xa tawm.
Ntoo cable nruas tsis tshua kim thiab siv dav hauv kev lag luam cable, txawm li cas los xij qhov kev nyiam ntawm ntoo yog qhov tseem ceeb. Pine thiab fir feem ntau yog siv, txawm li cas los xij cov ntaub siv yuav nyob ntawm tus neeg siv khoom xav tau. Cov nruas xa tawm feem ntau xav tau siab - cov khoom ntom ntom uas tiv taus kab thiab kab kab.
Cov khoom ntoo yog siv zog ua kom tawg los ntawm kev siv ib puag ncig, yog li qhov kub thiab av noo ntau dhau yuav tsum tau zam rau lub sijhawm siv. Lub caij no, ntau cov khoom siv hluav taws xob pov tseg tau ua tiav rau hauv cov rooj tsim nyog, cov rooj zaum, thiab cov rooj tog sib txawv, ua kom siv tag nrho cov khoom zoo hauv txoj kev tshwj xeeb, uas yog feem ntau nyiam los ntawm cov neeg nyiam khoom siv tes ua.
