7 × 7 Hlau hlua
- Kev tsim kho: 7 strands, txhua txoj hlua ua los ntawm 7 cov hlau me me
- Tag nrho cov xaim: 49 ib lub xaim
- Feature: Thick ib tug neeg nyob ntawm tej hauv strands, nruj qauv, tsis yooj yim
7 × 19 Hlau hlua
- Kev tsim kho: 7 strands, txhua txoj hlua qhwv los ntawm 19 cov hlau me me
- Tag nrho cov xaim: 133 ib leeg xaim
- Feature: Nyias ib leeg nyob rau hauv strands, mos, siab yooj
Kev sib piv lub zog sib piv (Tib txoj kab uas hla & qib khoom)
Raws li txoj hlua txoj kab uas hla zoo ib yam, cov khoom siv hlau, qib tensile thiab cov qauv tsim: 7 × 7 xaim hlua muaj ntau dua cov khoom tawg (muaj zog) dua 7 × 19.
Yog vim li cas:
1. Ib leeg hlau thickness sib txawv
7 × 7 siv cov hlau ib leeg tuab dua. Thicker hlau dais loj tensile quab yuam ib hlau, nrog tsawg kev sib cuag nto kev sib txhuam poob ntawm puab nyob ntawm tej.
7 × 19 txais ultra- xov hlau zoo; ntau cov ntsiab lus ntawm cov xov hlau sib txuas ua kom muaj kev sib txhuam ntau dua nyob rau hauv qhov nro, txo tag nrho qhov kawg ntawm kev quab yuam.
2. Hla -section zoo thaj tsam hlau
Ntawm qhov sib npaug ntawm txoj kab uas hla, 7 × 7 tawm me me ntawm cov xov hlau tuab, ua rau cov hlau ntoo loj dua -section. Cov hlau loj dua ncaj qha txhim kho tensile tawg lub zog.
Cov ntaub ntawv siv piv txwv (304 stainless hlau xaim hluaØ 3mm):
7 × 7 Ø3mm: Min tawg load ≈ 880 kgf
7 × 19 Ø3mm: Min tawg load ≈ 720 kgf
Daim ntawv thov Scenarios los ntawm lub zog yam ntxwv
Xaiv 7 × 7 (siab zog tensile, nruj)
Static tsau lashing, txiv neej hlau, guardrail cable
Luv-stroke qis-ntau zaus nqa, ncaj nro yam tsis muaj kev khoov ntau zaus
Rigid tswj cables, kev ruaj ntseg khi nrog siab load xav tau
Xaiv 7 × 19 (Lub zog tensile qis, hloov tau yooj yim)
Crane hoisting, winch hlua, of elevator tswj hlau
Ropes hla pulleys, nquag winding & reciprocating dabtsi yog khoov
Marine rigging, saj zawg zog mechanical kis cables
Cov Ntsiab Lus Ntxiv Ntxiv
- Yog tias ob txoj hlua sib txawv ntawm txoj kab uas hla: Txoj kab uas hla loj dua ib txwm muaj lub zog tawg ntau dua, uas overrides 7 × 7 lub zog kom zoo dua.
- Cov ntaub ntawv qib tseem ceeb heev: 316 stainless hlau, galvanized carbon steel, siab - tensile alloy steel hloov lub zog loj heev tsis hais txog kev tsim kho.
- Kev ua haujlwm ntawm kev nyab xeeb kev nyab xeeb: Txawm tias 7 × 7 muaj zog dua, kev ua haujlwm tiag tiag yuav tsum khaws qhov kev nyab xeeb ntawm 5 ~ 10 npaug ntawm qhov hnyav ua haujlwm, tsis txhob siv cov khoom tawg raws li kev tso cai.
Nrog tib txoj kab uas hla thiab steel khoom:
Static tensile zog:7 × 7 > 7 × 19
Flexibility & khoov qaug zog lub neej:7 × 19 > 7 × 7
Kev xaiv logic: Ua ntej 7 × 7 kom ruaj khov nro; xaiv 7 × 19 rau dynamic dabtsi yog khoov & winding ua hauj lwm tej yam kev mob.
