(1) Kev tshuaj xyuas yuav tsum tau ua ua ntej siv
Kev soj ntsuam xyuas: xyuas qhov hnav, corrosion, ncab, dabtsi yog khoov, deformation, qaug zog, tawg hlau, thiab qib ntawm cov hlua ntawm cov hlua hlau, thiab txiav txim siab nws qhov kev nyab xeeb nqa qhov hnyav (xws li scrapping).
(2) Kev saib xyuas ceev faj
1) Kev pabcuam lub neej ntawm cov hlua hlau muaj kev sib raug zoo nrog txoj kev siv, yog li nws yuav tsum tau siv raws li cov kev cai, txwv tsis pub rub thiab pov, thiab tsis pub dhau kev siv, thiab nws tsis yog. tso cai rau khoov cov hlua hlau ntawm lub kaum ntse ntse, thiab nws tsis raug tso cai los hloov qhov nrawm nrawm kom tsis txhob cuam tshuam kev thauj khoom.
2) Thaum muaj xeb thiab av hauv cov hlua hlau, txhuam nws nrog txhuam txhuam thiab siv roj
3) Cov hlua hlau yog oiled txhua 4 lub hlis, thiab nws yog qhov zoo tshaj plaws los ntub cov hlua hlua nrog cov roj kub (kwv yees li 50 degree) thaum oiling, thiab tom qab ntawd so cov roj ntau dhau.
4) Tom qab cov hlua hlau yog coiled, nws yuav tsum tau muab tso rau hauv qhov chaw huv si thiab qhuav, thiab yuav tsum tsis txhob muab tso rau sab saum toj ntawm ib leeg kom tiv thaiv kev sib tsoo.
5) Qhov kawg ntawm txoj hlua hlau yog nruj nrog steel hlau los yog welded nrog ib tug alloy nrog ib tug tsawg melting point, los yog nws yuav tsum tau nruj nreem nrog ib tug hlau hoop kom tsis txhob txoj hlua kawg ntawm loosening.
6) Hauv kev siv, yog tias muaj cov roj ntsha extruded rau saum npoo ntawm cov hlua hlau, nws txhais tau hais tias cov hlua hlau tau raug quab yuam ntau heev, thiab cov load yuav tsum tau nres, thiab kev soj ntsuam yuav tsum tau nqa tawm, thiab cov tshiab. cov hlua hlau yuav tsum tau hloov yog tias tsim nyog.
7) Lub peev xwm ntawm txoj hlua traction yuav tsum yog 5-8 zaug ntawm tag nrho cov traction quab yuam.
