Thaum twg yuav tsum tau muab cov hlua khi?
Taw qhia
Chain slings yog ib qho cuab yeej tseem ceeb rau ntau txoj haujlwm hauv kev lag luam, suav nrog rigging, nqa thiab ruaj khov. Raws li nrog rau txhua yam khoom siv, saw slings muaj lub neej ntev thiab yuav tsum tau saib xyuas tsis tu ncua kom ntseeg tau tias lawv muaj kev nyab xeeb siv. Qhov tshwm sim ntawm kev ua tsis tiav ntawm cov hlua khi tuaj yeem ua rau hnyav thiab ua rau raug mob, puas rau cov khoom siv, lossis txawm tias poob ntawm lub neej. Yog li ntawd, nws yog ib qho tseem ceeb kom paub thaum twg ib tug saw saw yuav tsum muab pov tseg. Kab lus no yuav tshawb txog cov xwm txheej uas txiav txim siab qhov kawg ntawm txoj hlua khi txoj hlua siv lub neej.
Yam tseem ceeb uas cuam tshuam rau cov saw saw hlau lifespan
Lub neej ntev ntawm ib txoj hlua khi yog nyob ntawm ntau yam, nrog rau qib hnav, corrosion, qaug zog, overload, thiab misalignment. Yog tias ib qho ntawm cov xwm txheej no tshwm sim, nws tuaj yeem ua rau cov saw hlau tsis muaj zog thiab ua rau muaj kev pheej hmoo ntawm kev ua tsis tiav. Kev tshuaj xyuas tsis tu ncua thiab kev saib xyuas kom zoo tuaj yeem pab ua kom lub neej ntev ntawm cov saw hlau. Cia peb tham txog txhua yam ntawm no kom ntxaws.
Hnav
Hnav yog ib qho ntawm feem ntau yam uas ua rau cov saw hlau tsis ua haujlwm. Chain slings raug kev sib txhuam, puas, thiab cuam tshuam thaum siv, uas tuaj yeem ua rau hnav ntawm cov saw txuas. Sij hawm dhau mus, kev hnav tuaj yeem ua rau elongation lossis deformation ntawm cov saw txuas, uas tuaj yeem ua rau lub sling tsis muaj zog thiab ua rau muaj kev pheej hmoo ntawm kev ua tsis tiav. Txhawm rau ntsuas qhov hnav, tshuaj xyuas cov hlua txuas rau elongation, deformation, tawg, lossis lwm yam cim ntawm kev puas tsuaj.
Corrosion
Corrosion yog lwm yam tseem ceeb uas yuav txo tau lub neej ntawm cov saw sling. Kev cuam tshuam rau cov dej noo, tshuaj, lossis lwm yam khoom corrosive tuaj yeem ua rau xeb, pitting, lossis lwm yam corrosion ntawm cov saw txuas. Corrosion ua rau cov hlau tsis muaj zog thiab ua rau nws yooj yim rau kev ua tsis tiav. Tshawb xyuas cov saw txuas rau cov cim qhia ntawm corrosion, xws li discoloration, xeb, los yog pitting.
Kev qaug zog
Kev qaug zog yog qhov ua kom tsis muaj zog ntawm cov khoom siv vim muaj kev ntxhov siab ntau ntxiv. Chain slings raug rau cyclic loading thaum siv, uas tuaj yeem ua rau qaug zog tsis ua haujlwm. Sij hawm dhau mus, cov hlau tuaj yeem tsim cov kab nrib pleb me me uas loj hlob mus rau hauv cov kab nrib pleb loj, nws thiaj li ua rau cov saw hlau tsis ua haujlwm. Tshawb xyuas cov hlua txuas rau cov cim ntawm kev qaug zog, xws li tawg lossis lwm yam kev puas tsuaj.
Tshaj dhau
Overloading ib tug saw sling tshaj nws lub peev xwm rated tuaj yeem ua rau tsis ua hauj lwm tam sim. Txawm tias ib qho overload tuaj yeem ua rau muaj kev puas tsuaj mus tas li rau cov saw txuas uas tsis tuaj yeem kho. Txhawm rau tiv thaiv overloading, nco ntsoov xyuas qhov hnyav ntawm lub nra ua ntej nqa nws thiab siv cov hlua khi nrog lub peev xwm tsim nyog.
Kev tsis ncaj ncees
Misalignment tshwm sim thaum lub saw sling tsis ua raws nraim nrog lub nra, ua rau muaj kev ntxhov siab khoov uas tuaj yeem ua rau tsis ua haujlwm. Ib txwm muab cov hlua hlua khi rau hauv txoj kab ncaj nraim nrog lub nra kom tsis txhob muaj kev sib tsoo.
Yuav ua li cas txiav txim siab thaum twg yuav muab pov tseg ib txoj hlua khi
Cov hlua khi yuav tsum tau muab pov tseg thaum lawv ncav cuag qhov kawg ntawm lawv lub neej muaj txiaj ntsig lossis thaum lawv tsis kuaj xyuas. Nws yog qhov zoo dua los hloov cov saw hlau ua ntej nws ua tsis tiav hauv kev pabcuam, vim tias tsis ua haujlwm tuaj yeem ua rau muaj qhov tshwm sim loj.
Cov neeg tsim khoom ntawm cov saw slings muab cov lus qhia ntawm qhov zaus ntawm kev tshuaj xyuas, cov txheej txheem rau kev tsis lees paub, thiab kev cia siab rau lub neej ntawm cov hlua. Ua raws li cov lus qhia no kom muaj kev nyab xeeb ntawm cov khoom siv.
Yog tias ib qho ntawm cov xwm txheej tau hais los saum toj no, nws yog qhov zoo tshaj kom muab cov saw sling pov tseg. Cov cim qhia ntawm elongation, deformation, tawg, lossis lwm yam kev puas tsuaj tuaj yeem qhia tau tias hnav, corrosion, qaug zog, los yog overload. Cov cim ntawm xeb, pitting, los yog lwm yam ntaub ntawv ntawm corrosion yuav qhia tau hais tias corrosion. Cov tsos mob ntawm kev tawg lossis lwm yam kev puas tsuaj tuaj yeem qhia tias qaug zog. Ib txwm ntsuas cov saw hlau raws li cov txheej txheem tshuaj xyuas los ntawm cov chaw tsim khoom.
Xaus
Hauv kev xaus, saw slings yog cov cuab yeej tseem ceeb hauv kev lag luam uas yuav tsum tau kuaj xyuas thiab tu kom zoo kom ntseeg tau tias lawv muaj kev nyab xeeb siv. Lub neej ntev ntawm ib txoj hlua khi yog cuam tshuam los ntawm ntau yam, xws li hnav, corrosion, qaug zog, overload, thiab misalignment. Txhawm rau txiav txim siab thaum twg yuav muab cov hlua khi hlua khi, tshuaj xyuas nws tsis tu ncua thiab ua raws li cov txheej txheem tshuaj xyuas thiab cov txheej txheem kev ua neej nyob uas muab los ntawm cov chaw tsim khoom. Cov cim ntawm kev hnav, corrosion, qaug zog, overload, los yog misalignment tuaj yeem qhia tau tias cov hlua khi tau mus txog qhov kawg ntawm nws lub neej muaj txiaj ntsig thiab yuav tsum tau muab pov tseg. Nco ntsoov saib xyuas kev nyab xeeb thaum siv cov hlua khi, vim tias qhov tshwm sim ntawm kev ua tsis tiav tuaj yeem hnyav heev.
