Raws li peb txhua tus paub, crane qhov chaw yog qhov tseem ceeb hauv kev nqa khoom. Peb paub tias muaj ntau yam lifting qhov chaw, xws li lub log, hooks, hlau ropes, hlua qhia, thiab lwm yam. Crane nuv yog ib qho khoom siv feem ntau siv hauv lifting accessories. Nws yog tsuas yog siv los nqa cov khoom lossis cov khoom siv, yog li nws cov kev xav tau zoo yog nruj heev.
Yuav ua li cas yuav tsum tau hloov ib tug nuv tshiab?
Thaum ib qho ntawm cov xwm txheej hauv qab no tshwm sim, lub crane nuv yuav tsum tau hloov tam sim ntawd.
1. Thaum tus nuv muaj kab nrib pleb, nws yuav tsum tau muab pov tseg.
2. Thaum hnav qib ntawm qhov txaus ntshai ntawm tus nuv mus txog 10% ntawm qhov loj me, nws yuav tsum tau muab pov tseg tam sim ntawd.
3. Thaum qhov qhib degree ntawm tus nuv nce 15% piv nrog rau qhov loj me, nws yuav tsum tau muab pov tseg tam sim ntawd.
4. Thaum lub torsional deformation ntawm tus nuv tshaj 10¡ã, nws yuav tsum tau muab pov tseg tam sim ntawd.
5. Thaum qhov txaus ntshai ntawm tus nuv lossis lub caj dab ntawm tus nuv muaj cov yas deformation, nws yuav tsum tau muab pov tseg tam sim ntawd.
6. Thaum lub tes tsho nuv ntawm lub phaj nuv yog hnav mus rau 5% ntawm qhov loj me, lub tes tsho nuv yuav tsum tau muab pov tseg.
7. Thaum lub mandrel ntawm tus nuv phaj yog hnav mus rau 5% ntawm qhov loj me, lub mandrel yuav tsum tau muab pov tseg.
Lub crane nuv yog ib qho tseem ceeb ntawm cov khoom siv crane, thiab nws cov kev saib xyuas yog qhov tseem ceeb los xyuas kom meej tias cov khoom siv ua haujlwm zoo. Nov yog qee qhov kev ceev faj rau kev saib xyuas nuv ntses:
Tsis tu ncua xyuas qhov hnav thiab deformation ntawm tus nuv:
Hooks yog nquag hnav, deformation, tawg thiab lwm yam teeb meem thaum siv mus sij hawm ntev, yog li nws yog ib qho tsim nyog yuav tsum tsis tu ncua xyuas cov tsos ntawm tus nuv kom paub tseeb tias nws tsis muaj kev puas tsuaj.
Tshawb xyuas qhov qhib, nuv, swb thiab lwm qhov chaw ntawm tus nuv kom paub tseeb tias tsis muaj hnav lossis deformation.
Saib xyuas lub lubrication mob ntawm tus nuv:
Tus nuv yuav tsum tau lubricated tsis tu ncua, tshwj xeeb tshaj yog cov hinged ib feem ntawm tus nuv, kom txo tau kev sib txhuam thiab ntev kev pab cuam lub neej.
Siv cov roj lubricating tshwj xeeb, xyuas kom meej tias cov roj lubricating tsis tas sijhawm, thiab hloov nws tsis tu ncua.
Tshawb xyuas lub zog thiab kev nyab xeeb ntawm tus nuv:
Cov khoom siv thiab lub zog ntawm tus nuv yuav tsum ua tau raws li cov qauv tsim, thiab tus nuv yuav tsum tsis txhob siv tshaj qhov ntsuas load.
Xyuas seb tus nuv puas muaj qhov tawg lossis qaug zog, tshwj xeeb tshaj yog thaum nqa cov khoom hnyav.
Hook welding soj ntsuam:
Vuam qhov chaw ntawm tus nuv yuav tsum tau kuaj xyuas tsis tu ncua kom tsis txhob muaj kab nrib pleb lossis vuam tsis zoo.
Yog tias pom muaj teeb meem, tus nuv yuav tsum tau kho lossis hloov lub sijhawm.
Marking thiab siv cov hooks:
Hooks yuav tsum tau cim kom meej meej nrog lub peev xwm thauj khoom siab tshaj plaws kom ntseeg tau tias cov neeg ua haujlwm yuav tsis dhau lub sijhawm siv lawv.
Nws yog nruj me ntsis txwv tsis pub sib tov hooks nrog lwm cov cuab yeej lossis cov cuab yeej siv kom tsis txhob ua rau cov hooks puas lossis txo lawv lub neej kev pabcuam.
Ua kev ntsuam xyuas kev nyab xeeb ntawm hooks tsis tu ncua:
Load xeem ntawm hooks yuav tsum tau ua nyob rau hauv lub sij hawm teem tseg los xyuas lawv lub peev xwm load.
Thaum lub sij hawm sim, tsis txhob tshaj qhov kev nyab xeeb ntawm cov hooks.
Kev khaws cia thiab tu cov hooks:
Thaum tsis siv, cov hooks yuav tsum tau muab cia rau hauv qhov chaw qhuav, qhov cua zoo kom tsis txhob muaj xeb lossis puas tsuaj rau cov hooks.
Hooks yuav tsum khaws cia kom deb ntawm cov khoom ntse kom tiv thaiv kev puas tsuaj rau cov hooks.
Los ntawm kev saib xyuas tsis tu ncua thiab kev tshuaj xyuas, kev nyab xeeb thiab kev ntseeg siab ntawm cov hooks tuaj yeem ua kom ntseeg tau, qhov tshwm sim ntawm kev ua tsis tiav tuaj yeem raug txo, thiab kev nyab xeeb ntawm kev nqa haujlwm tuaj yeem ua kom ntseeg tau.
