Lub ntsiab nqaj ntawm lubib leeg-girder choj craneyog qhov tsis sib xws, uas cuam tshuam ncaj qha rau kev ua haujlwm tom ntej. Ua ntej, peb yuav daws qhov flatness ntawm lub nqaj ua ntej mus rau txheej txheem tom ntej. Tom qab ntawd lub sandblasting thiab plating lub sij hawm yuav ua rau cov khoom whiter thiab flawless. Txawm li cas los xij, choj cranes nrog cov qauv sib txawv thiab cov kev txwv muaj cov yam ntxwv sib txawv ntawm lawv cov kab teeb tseem ceeb. cov
Peb yuav tsum xub nkag siab txog ob lub ntsiab lus hauv qab no txog cov khoom:
1. Cov ntaub ntawv dab tsi thiab cov duab ntawm lub rooj tsavxwm yuav tsum tau ua rau lub ntsiab nqaj ntawm lub tshuab choj (cov laug cam, yob, qhov tshwj xeeb zoo li tus, cov kav)?
2. Xav txog qhov loj ntawm lub ntsiab nqaj thiab qhov chaw ntawm ib leeg-girder crane (nyob ntawm cov khoom, cov txheej txheem sib txawv tuaj yeem raug xaiv los ua kom tiav cov nqi thiab kev tswj hwm kev ua haujlwm), hom kev ua haujlwm zoo li cas thiab kev siv yuav tsum tau ua tiav rau lub ntsiab nqaj?
Tam sim no, muaj ob txoj hauv kev los daws qhov flatness ntawm lub ntsiab nqaj ntawm crane:
1. Kev siv cov khoom siv kho tshuab yog tshem tawm cov polished convex qhov chaw los ntawm kev txiav thiab yas deformation ntawm cov khoom nto kom tau ib txoj kev du nto polishing, thiab feem ntau yog siv cov pob zeb sib tsoo, polishing kua, thiab lwm yam.
2. Tshuaj polishing. Tshuaj polishing yog ua kom lub microscopic convex qhov chaw ntawm lub zos convexity ntawm cov ntaub ntawv dissolve ua ntej nyob rau hauv cov tshuaj nruab nrab, yog li tau ib tug du nto. Lub ntsiab kom zoo dua ntawm txoj kev no yog cov complex workpieces yuav polished yam tsis muaj cov cuab yeej nyuaj, thiab ntau steel phaj yuav polished ib txhij. Qhov teeb meem nrog tshuaj polishing yog siv cov kua polishing thiab cov khoom siv. Qhov saum npoo roughness tau los ntawm tshuaj polishing feem ntau yog 10μm.
