Thaum xaiv cov kev qhia tshwj xeeb ntawm kev nqa txoj siv, qhov loj, qhov hnyav, cov duab ntawm lub thauj khoom yuav tsum tau nqa, thiab txoj kev nqa nqa yuav tsum tau coj mus rau hauv tus account hauv kev suav ntawm kev siv coefficient, txwv kev ua haujlwm quab yuam, thiab qhov chaw ua haujlwm thiab hom kev thauj khoom yuav tsum raug txiav txim siab. Nws yog ib qho tsim nyog yuav tau xaiv ib txoj hlua uas muaj peev xwm txaus thiab qhov ntev kom haum raws li kev siv. Yog tias siv ntau txoj hlua nqa nqa los nqa lub nra tib lub sijhawm, tib hom nqa nqa yuav tsum raug xaiv; cov khoom siv ntawm lub tiaj lifting siv tsis tuaj yeem cuam tshuam los ntawm ib puag ncig lossis kev thauj khoom. Txawm hais tias yuav tsum muaj cov khoom siv lossis cov pob ntseg muag muag, qhov kawg ntawm txoj siv nqa nqa yuav tsum tau ua tib zoo txiav txim siab kom phim cov khoom siv txhawb nqa thiab cov khoom nqa.
Nta
Lub teeb yuag thiab mos: Qhov hnyav yog 25% ntawm tib lub hlau nqa sling. Lub sling yog yooj yim heev los tswj, nqa thiab khaws cia. Yog hais tias muaj ib tug loj txiav ntawm lub round lifting siv tes tsho, nws yuav tsum tau soj ntsuam thiab tsis tuaj yeem kho los yog siv dua.
Hais txog cov yam ntxwv thiab kev siv ntawm txoj siv nqa nqa
Lifting siv tau nce siv nyob rau hauv niaj hnub, thev naus laus zis thiab thoob ntiaj teb lifting qhov chaw. Cov khoom siv dav siv hauv kev nqa hauv steel mills, roj teb, chaw nres nkoj, electromechanical, tsheb thauj mus los thiab lwm yam lag luam.
(1) Lub teeb yuag, hloov tau yooj yim, khoov tau yooj yim, siv tau yooj yim;
(2) Tsis txhob ua kom lub ntsej muag ntawm cov khoom raug hoisted, muaj zog tu;
(3) ruaj khov nqa, muaj kev nyab xeeb siab;
(4) Muaj lub zog tensile siab, xim zoo nkauj, yooj yim rau kev paub qhov txawv;
(5) Yog ib qho insulator;
(6) Lub lifting siv muaj lub neej ntev, zoo corrosion kuj thiab hnav tsis kam;
(7) Txhim kho kev ua haujlwm ntawm kev ua haujlwm thiab txuag nqi;
(8) Siv dav, dav siv hauv aviation, aerospace, nuclear fais fab kev tsim kho, kev tsim tub rog, chaw nres nkoj thiab tshem tawm, cov khoom siv hluav taws xob, kev siv tshuab, tshuaj hlau, nkoj tsim, kev thauj mus los thiab lwm yam.
Kev sib txawv
Feem ntau, nws qhov dav yog 15 hli, 30 hli, 50 hli, 60 hli, nqa txoj siv sia, nqa txoj siv sia: muaj zog silk warp woven rau hauv dyed industrial webbing. Lifting siv, 75mm, 90mm, 100mm, 120mm, 150mm, 180mm, 240mm, 300mm, qhov dav ntawm lub log yog 30mm, 50mm, 60mm, 70mm, 80mm, 100mm.
Kev lag luam webbing yog sewn rau hauv lub tiaj nqa txoj siv los ntawm kev lag luam. Txawm li cas los xij, yog tias tus neeg siv tsis paub meej txog qhov kev puas tsuaj, nws yog qhov zoo tshaj kom xa cov hlua nqa nqa rov qab mus rau cov chaw tsim khoom rau kev tshuaj xyuas ntxiv. Lub nplhaib lifting siv yog ib lub nplhaib xwb. Thaum lub load-cov tub ntxhais bearing yog ib feem puas vim yog overload los yog siv ib ntus, nws lub tsho yuav ua ntej tawg los ceeb toom thiab tsis txhob muaj xwm txheej.
Synthetic fiber lifting siv yog ib tug mos sling nrog kev ua tau zoo heev. Nws yog ua los ntawm high-zoo siab-lub zog thiab qis-stretch polyester filament thiab yog ib qho khoom hloov rau cov hlua hlau. Nws tau dav siv nyob rau hauv industrially tsim lub teb chaws thoob ntiaj teb rau ntau tshaj 50 xyoo. Nws tsis ua kev puas tsuaj rau saum npoo ntawm cov khoom dai (nrog rau cov xim txheej) thiab tsis ua rau muaj kev puas tsuaj rau tib neeg lub cev.
Feem ntau, nqa txoj siv tawv yog qhov nyuaj rau corrode thiab tsis yog - conductive. TA hom lifting siv yog ib lub nplhaib- zoo li tus hlua nrog hnav- tiv thaiv sab nrauv thiab lub siab- hlua hlua hauv lub cev (tseem hu ua "universal sling", yog ib qho ntawm cov khoom siv dav tshaj plaws). Round lifting siv yog tsim los ntawm infinitely encircled sib npaug sib npaug zos cab los tsim ib tug kaw load- bearing core, thiab yog twisted nrog ib tug strands ntawm hlau. Tus naj npawb ntawm cov xov hlau hauv ib kab nce mus txog ntau dua 100,000 lub voj voog, uas ua lub luag haujlwm thauj khoom{10}}. Synthetic fiber lifting siv yog mos thiab yooj yim los tswj.
Kev ua tau zoo thiab qhov zoo
Kev ua tau zoo:
Lub zog: 1T-30T Round lifting siv 1T-300T
Bandwidth: 25mm-250mm
Elastic elongation:<10% under rated load 2%-3% under ultimate working force
Load identification: Thaum siv, daim ntawv lo ntawm lub sling tuaj yeem hnav thiab lub nra hnyav tuaj yeem txheeb xyuas los ntawm cov xim ntawm lub tsho sling.
Ua haujlwm kub: -40 ~ 100℃Kev nyab xeeb yam: 5:1 6:1 7:1
Qhov zoo:
1. Lub teeb yuag thiab yooj yim siv;
2. Tsis muaj kev puas tsuaj rau saum npoo ntawm cov khoom raug hoisted;
3. ruaj khov thiab ruaj ntseg nqa;
4. Lub zog siab, tonnage tuaj yeem txiav txim los ntawm xim;
5. Txhim kho kev ua haujlwm thiab kev txuag nqi;
6. Zoo corrosion kuj thiab hnav tsis kam;
7. Siv dav, haum rau cov chaw nres nkoj, chaw nres nkoj, tshuaj lom neeg, hlau, tshuab, kev teeb tsa thiab lwm qhov chaw nqa khoom.
