Load Test Requirements rau Stainless Hlau Hlau Rope

Daim ntawv qhia ua kom tiav rau kev nyab xeeb, cov qauv, thiab kev ua raws li cov ntawv thov kev lag luam

Stainless hlau xaim hlua yog ib qho tseem ceeb hauv kev thauj khoom thiab tensioning systems thoob plaws ntau yam lag luam - los ntawm kev tsim kho thiab kev siv dej hiav txwv mus rau elevators thiab overhead lifting. Ib qho tseem ceeb uas ua kom nws muaj kev nyab xeeb thiab siv tau zoo yogload kuaj.

Kab lus no tshawb txog qhovload xeem cov cai raustainless hlau hlau hlua, npog hom kev xeem, qauv, zaus, cov ntaub ntawv, thiab kev ua raws li kev lag luam tshwj xeeb. Txawm hais tias koj yog ib tus neeg cog lus rigging, project engineer, lossis tus kws tshaj lij kev muag khoom, kev nkag siab txog cov txheej txheem kuaj xyuas yog qhov tseem ceeb rau kev tswj xyuas kev nyab xeeb thiab kev ntseeg siab.

Load Testing yog dab tsi?

Load xeemyog tus txheej txheem ntawm kev siv lub zog tswj mus rau ib qho hlau stainless hlau hlua los xyuas nws cov kev ua tau zoo raws li qhov xav tau ua haujlwm. Kev ntsuas ntsuas:

• Kev tawg(Qhov kawg Tensile Strength)

• Ua haujlwm Load Limit (WLL)

• Elastic deformation

• Kev txheeb xyuas kev nyab xeeb

• Manufacturing defects los yog flaws

Kev ntsuas kev thauj khoom kom ntseeg tau tias txoj hlua hlau tuaj yeem ua tau zoo nyob rau hauv cov ntawv thov tiag tiag yam tsis muaj kev ua haujlwm.

Vim li cas Load Testing tseem ceeb?

Kev ua tsis tiav ntawm txoj hlua hlau hauv kev pabcuam tuaj yeem ua rau:

• Kev raug mob lossis tuag

• Cov cuab yeej puas

• txhaum cai

• Kev ua haujlwm poob qis

Yog li ntawd, nruj load kuaj yog qhov tseem ceeb rau:

• Validate cov khoom zoo

• Ua raws li cov cai tswj hwm thiab kev tuav pov hwm

• Ua kom cov neeg siv khoom muaj kev ntseeg siab

• Ua kom muaj kev ruaj ntseg ntawm cov qauv thiab cov kabmob load

Cov ntsiab lus tseem ceeb hauv Load Test

Ua ntej dhia mus rau hauv cov txheej txheem xeem, nws yog ib qho tseem ceeb kom nkag siab qee cov ntsiab lus tseem ceeb:

• Lub zog tawg (BS): Lub zog siab tshaj plaws ntawm txoj hlua tuaj yeem tiv taus ua ntej tawg.

• Ua haujlwm Load Limit (WLL): Lub load siab tshaj plaws uas yuav tsum tau siv thaum lub sijhawm ua haujlwm niaj hnub - feem ntau1/5 txog 1/12ntawm lub zog tawg, nyob ntawm daim ntawv thov.

• Pov thawj Load: Ib qho kev xeem tsis muaj kev puas tsuaj, feem ntau yog teem rau50% txog 80%ntawm qhov tsawg kawg nkaus tawg load, siv kom paub meej tias kev ncaj ncees yam tsis muaj kev puas tsuaj rau txoj hlua.

Cov qauv siv tau rau Load Test

Ntau tus qauv thoob ntiaj teb txhais li casstainless hlau hlau hluayuav tsum tau kuaj. Qee qhov suav nrog:

• TS EN 12385-1: European tus qauv rau steel hlau hlua kev nyab xeeb thiab kuaj

• TS EN ISO 3108: Cov txheej txheem rau kev txiav txim siab tawg

• ASTM A1023 / A1023M ASTM A1023 / ASTM A1023 / TS: American standard for mechanical testing

• ASME B30.9: US tus qauv kev nyab xeeb rau slings nrog rau cov hlua hlau

• Lloyd's Register / DNV / ABS: Marine thiab offshore faib cov koom haum nrog rau cov txheej txheem kuaj tshwj xeeb

sakysteel uaua raws li cov qauv ntsuas thoob ntiaj teb thiab tuaj yeem muab cov hlua nrog cov ntawv pov thawj los ntawm ABS, DNV, thiab cov neeg soj ntsuam thib peb raws li qhov xav tau.

Hom Load Test rau Stainless Hlau Hlau Rope

1. Destructive Testing (Tshuaj Load Test)

Qhov kev sim no txiav txim siab qhov tseebtawg zogntawm ib tug qauv los ntawm rub nws mus txog rau thaum tsis ua hauj lwm. Nws feem ntau ua tiav ntawm cov qauv qauv lossis thaum lub sijhawm tsim khoom.

2. Pov thawj Load Test

Qhov kev ntsuam xyuas tsis muaj kev puas tsuaj no txheeb xyuas qhov ua tau zoo hauv kev thauj khoom yam tsis pub dhau txoj hlua elastic txwv. Nws xyuas kom meej tias tsis muaj slippage, elongation, los yog tsis xws luag tshwm sim.

3. Cyclic Load Test

Ropes raug rov ua dua lub voj voog ntawm kev thauj khoom thiab tshem tawm los ntsuas kev qaug zog tiv thaiv. Qhov no yog qhov tseem ceeb rau cov hlua siv hauv elevators, cranes, lossis ib qho kev thauj khoom dynamic.

4. Visual thiab Dimensional Inspection

Thaum tsis yog "kev sim thauj khoom," qhov no feem ntau ua nrog cov pov thawj kev kuaj xyuas kom pom qhov tsis zoo, cov xov hlau tawg, lossis qhov tsis sib xws hauv kev sib dhos.

Ntau zaus ntawm Load Test

Load xeem yuav tsum tau sib txawv los ntawm kev lag luam thiab daim ntawv thov:

Txoj hlua siv hauv kev nyab xeeb-tseem ceeb yuav tsum yogrov kuaj dua tom qab muaj kev xav tias overload lossis mechanical puas.

Tej yam uas cuam tshuam rau Load Test Results

Ntau qhov sib txawv tuaj yeem cuam tshuam li cas astainless hlau hlau hluaua raws li kev kuaj load:

• Kev tsim kho txoj hlua(eg, 7 × 7 vs 7 × 19 vs 6 × 36)

• Cov ntaub ntawv qib(304 vs 316 stainless hlau)

• Lubrication thiab corrosion

• Xaus kev txiav tawm (swaged, socketed, thiab lwm yam)

• Khoov tshaj sheaves los yog pulleys

• Kub thiab ib puag ncig raug

Vim li no, nws yog ib qho tseem ceeb uas yuav tau ua cov kev ntsuam xyuas sivcov qauv hlua tiag tiag hauv tib yam mob thiab kev teeb tsaraws li lawv yuav raug siv hauv kev pabcuam.

Load Test Documentation

Kev kuaj xyuas kom zoo yuav tsum muaj xws li:

• Chaw tsim tshuaj paus cov ntsiab lus

• Txoj hlua hom thiab kev tsim kho

• Txoj kab uas hla thiab qhov ntev

• Test hom thiab txheej txheem

• Pov thawj load los yog tawg load tiav

• Cov txiaj ntsig dhau / poob

• Hnub tim thiab qhov chaw xeem

• Kos npe ntawm cov neeg soj ntsuam lossis cov ntawv pov thawj

Cov Lus Qhia Txog Kev Nyab Xeeb Kev Nyab Xeeb

Yam tsawg kawg nkausKev Nyab Xeeb Kev Nyab Xeeb (SF)siv rau cov hlua hlau sib txawv los ntawm kev siv:

Kev nkag siab thiab siv qhov tseem ceeb ntawm kev nyab xeeb kom raug ua raws li kev cai thiab txo qis kev pheej hmoo.

Vim li cas thiaj xaiv sakysteel rau Certified Hlau Rope?

• Cov ntaub ntawv zoo 304 thiab 316 stainless hlau

• Factory load kuaj thiab cov ntaub ntawv pov thawj

• Kev cai sib dhos nrog kuaj kawg fittings

• Ua raws li EN, ISO, ASTM, thiab cov qauv dej hiav txwv

• Kev xa khoom thoob ntiaj teb thiab lub sijhawm hloov pauv sai

Seb rau kev tsim kho, marine, architectural, los yog kev lag luam siv,sakysteel uaxa stainless hlau hlua uas yogload-tested, traceable, thiab txhim khu kev qha.

Xaus

Load test tsis yog xaiv tau - nws yog ib qho tseem ceeb los xyuas kom meej qhov kev ua tau zoo thiab kev nyab xeeb ntawm stainless hlau hlua hlua. Txawm hais tias siv nyob rau hauv qhov tseem ceeb lifting kev khiav hauj lwm, structural tensioning, los yog dynamic rigging systems, xyuas cov load peev xwm los ntawm standardized xeem yuav txo tau txoj kev pheej hmoo thiab txhim kho lub neej ntev.

Los ntawm kev ua kom puas tsuaj rau cov ntaub ntawv pov thawj tsis muaj kev puas tsuaj, cov ntaub ntawv xeem kom raug thiab ua raws li cov qauv kev lag luam yog qhov tseem ceeb.
