Cov lifting chains uas tsim los ntawm cov tuam txhab tsis tu ncua yuav tsum tau kuaj xyuas txheej txheej. Cov ntaub ntawv yog ua tib zoo xaiv thiab raug rau kub quenching. Cov txheej txheem tsim khoom zoo heev. Ua ntej yuav tawm hauv lub Hoobkas, cov hlua nqa nqa tau raug kuaj nruj tensile. Lawv tuaj yeem nkag mus rau hauv kev lag luam tsuas yog tom qab txhua yam tsim nyog. Yog li ntawd, lifting chains nyob rau hauv ib txwm siv yuav tsis tawg. Yog hais tias lub lifting chains tawg tam sim ntawd thaum siv, nws yuav tshwm sim los ntawm cov hauv qab no yog vim li cas.
Schematic Daim duab ntawm Broken Lifting Chain
1. Kev hnyav dhau yog qhov ua rau muaj kev puas tsuaj ntawm cov saw nqa. Qhov tsim nyog lifting saw muaj ib qho kev nyab xeeb zoo. Txawm hais tias nws yog siv nyob rau hauv overload, nws yuav tsis dheev tawg. Kev puas tsuaj tam sim ntawd yog tias qhov hnyav ntawm lub hom phiaj nqa nws tus kheej tau tshaj ob peb zaug ntawm qhov ntsuas ntawm cov saw nqa, uas yog, nws tag nrho tshaj qhov kev nyab xeeb ntawm cov saw nqa.
2. Lub lifting saw tau siv rau lub sijhawm ntev yam tsis muaj kev saib xyuas zoo, thiab kev xeb loj tau tshwm sim. Hauv qhov no, lub lifting saw yuav tsum tau muab pov tseg. Lub corroded lifting saw twb poob nws thawj rated load. Lub sijhawm no, nws tsis tuaj yeem xav tau los ntawm kev thauj khoom tsuas yog tawm hauv lub hoobkas. Txawm hais tias kev ua haujlwm tau ua tiav nyob rau hauv qhov ntsuas qhov ntsuas, nws tseem yuav ntsib txoj kev pheej hmoo ntawm kev tawg sai sai.
3. Kev siv lub sij hawm ntev overloading ntawm lub lifting saw yuav ua rau cov hlau tsis zoo. Yog tias qhov tawg tam sim ntawd ntawm cov saw nqa tsis tau tshwm sim nyob rau hauv qhov xwm txheej ntawm qhov hnyav dhau, nws muaj feem yuav tshwm sim nyob rau hauv lub sijhawm ntev overload. Txhua qhov kev ua haujlwm dhau los yuav muaj qhov cuam tshuam tsis zoo rau cov saw nqa, ib yam li peb tus kheej tib neeg. Yog tias peb tsis saib cov teeb meem me, nws yuav ua rau muaj kab mob loj heev. Lub lifting saw yog xws li ib tug gradual kev puas tsuaj. Yog tias koj tsis xyuam xim rau cov qauv kev ua haujlwm thiab kev saib xyuas ntawm lub sijhawm zoo tib yam, koj yuav tawg sai sai.
