Steel hlau ropes - ib qho txhais thiab yooj yim tsis

Galvanized steel hlua - qhov no Torsion ntawm lub steel hlau khoom. Siv nyob rau hauv nws cov kev siv thiab nyias rods (filaments) sib txawv ntawm cov thickness thiab zoo. lawv tag nrho cov wove ib tug kauv nyob rau hauv ib tug strand. Tej hlua muaj ob peb strands cov thiab zoo xws li cov nws yog xim hlau los yog organic cov tub ntxhais. Cov tub ntxhais nyob rau hauv qhov chaw ntawm lub hlua, nws nyob ib lub chaw khoob thiab tiv thaiv ntog los ntawm cov uas nyob ib sab hlau stranding. Impregnated nrog anti-xeb roj, nws tiv thaiv lub puab txheej ntawm xeb los ntawm dabtsi yog khoov lub cable. Cov siv hlau tej zaum yuav galvanized los yog uncoated, muaj ib puag ncig los yog zoo li tus ntoo khaub lig seem. Nws tensile zog ntawm so nyob rau hauv ntau ntawm 900 rau 3500 N / mm2. Cov nab npawb ntawm cov strands nyob rau hauv cov hlua uas yog pov tseg nyob ib ncig ntawm cov tub ntxhais, txiav txim nws cov qauv.

Steel hlau ropes yog txawv los ntawm txhua lwm yam ntoo khaub lig-sectional zoo, lub cev thiab cov neeg kho tshuab cov yam ntxwv ntawm cov hlau thiab muaj ib tug loj tus naj npawb ntawm designs. Los ntawm qib material, xws li ib tug tub ntxhais stranding kev taw qhia, tus naj npawb ntawm tej nyob rau hauv lub strands nyob ntawm seb qhov yooj thiab mob heev ntawm txoj hlua. Qhov ntau dua cov kev siv ntawm tej, cov hlua yog ntau saj zawg zog.

Nyob rau hauv lub khiav hauj lwm tej yam kev mob ntawm steel ropes muab faib mus rau hauv traction, reinforcing, lifting, tsheb thauj khoom, towing, ncej, kev coj tus kheej thiab lwm tus. Cov coob leej ntau tus siv ntawm cov khoom uas muaj tau txais nyob rau hauv ntau industries thiab hlauv taws xob. Steel ropes yog load-nqa lub caij uas thauj, kev-tsev, hoisting chaw thiab cov cav tov. Qhov zoo tshaj ntawm cov pab kiag li lawm kom muaj kev nyab xeeb siv kev txhawb nqa khoom.

Raws li tsim nta ib tug steel hlua (GOST 3241-80 thiab DIN 3051) paub qhov txawv cov nram qab no:

1. Tib stranding. Qhov no cable muaj ib zaug xwb strand. Nws muaj ib tug hlau kab uas hla Tsim nyob rau hauv ib txheej (los yog ntau khaubncaws sab nraud povtseg) nyob ib ncig ntawm ib tug tib hlau.
2. Dual stranding. Qhov no hlua muaj ob peb strands uas comprise ib los yog ob khaubncaws sab nraud povtseg, thiab cov txheej txheem ntawm nyob ib ncig ntawm cov tub ntxhais.
3. Triple nteg. Nws muaj peb strands uas Tsim interconnected thiab tsis muaj cov tub ntxhais.

Tso strands yuav ua tau Phillips, ib los yog tag nrho, sab laug los yog txoj cai kev taw qhia, los yog unwinds lub Torsion neraskruchivayuschegosya txoj kev. Hauv lub hlau strands muaj ib tug taw tes, kab los yog taw tes-linear hu.

Steel hlau ropes tsiag ntawv los ntawm cov nram qab no mis: N * M + L, qhov twg N - tus naj npawb ntawm strands, M - cov nyob ntawm tej nyob rau hauv ib tug strand, L - tus naj npawb ntawm cores nyob rau hauv txoj hlua. Piv txwv li, nkag 36 * 6 + 1 txhais tau tias cov hlua muaj rau strands, txhua yam uas yog 36 nyob ntawm tej thiab ib cov tub ntxhais.

Steel cables yuav tsum tau khaws cia lub qhov txhab nruj nreem nyob rau hauv kab nyob rau hauv lub reels (yob) los yog daim ntau quav tso rau hauv ib tug me me bay. Los ntawm cov teebmeem ntawm kev txhoj puab heev puag ncig bay nrog cable yuav tsum tau muaj kev tiv thaiv canvas cover yog muab tso rau ib tug ntoo pallet (nyob rau hauv tshav ntuj huab cua cover yog muab tshem tawm). Rau teeb meem ntev cable khoov rau ob sab. Yog li ntawd, ntim rau nws xaiv kom zoo zoo. Thaum zoo muab hlua lub neej ntawm cov khoom tsis yog.
