Kev tshuaj xyuas ua ntej siv
Kev soj ntsuam xyuas: Tshawb xyuas cov hlua hlau rau hnav, corrosion, nro, dabtsi yog khoov, deformation, qaug zog, tawg xov hlau, thiab cov℃ntawm cov tub ntxhais raug mob los txiav txim siab nws txoj kev nyab xeeb lifting peev (suav nrog scrapping).
Kev Tiv Thaiv Kev Tiv Thaiv
(1) Kev pabcuam lub neej ntawm cov hlua hlau yog qhov cuam tshuam zoo heev los ntawm txoj kev siv. Yog li ntawd, nws yuav tsum tau siv raws li kev cai. Drag thiab pov yog txwv tsis pub. Tsis pub dhau lub sijhawm siv. Sharp -lub kaum sab xis khoov ntawm txoj hlua hlau raug txwv. Sudden hloov hauv lifting ceev yog txwv tsis pub kom tsis txhob cuam tshuam loads.
(2) Yog tias txoj hlua hlau muaj xeb thiab av, txhuam nws nrog txhuam txhuam thiab siv roj.
(3) Siv roj rau txoj hlua hlau txhua 4 lub hlis. Thaum thov cov roj, nws yog qhov zoo tshaj plaws los ntub cov hlua khi nrog cov roj kub (kwv yees li 50 degree) thiab tom qab ntawd so cov roj ntau dhau.
(4) Tom qab coiling, cov hlua hlau yuav tsum muab tso rau hauv qhov chaw huv si thiab qhuav. Tsis txhob muab tso rau kom tsis txhob sib tw.
(5) Ruaj ntseg qhov kawg ntawm cov hlua hlau nrog cov hlau hlau los yog welded nrog qis - melting - taw tes alloy. Hlau hoops kuj tseem siv tau los zawm qhov kawg kom tsis txhob xoob.
(6) Yog hais tias cov roj tee yog nyem tawm ntawm qhov chaw ntawm cov hlua hlau thaum siv, nws qhia tau tias cov hlua hlau tau raug quab yuam ntau heev. Lub sijhawm no, lub load yuav tsum tau nres, thiab txoj hlua yuav tsum tau kuaj xyuas. Hloov cov hlua hlau yog tias tsim nyog. (7) Lub load-cov kabmob muaj peev xwm ntawm txoj hlua traction hlau yuav tsum yog 5-8 npaug ntawm tag nrho cov traction quab yuam.
