Dab tsi yog qee qhov kev tsim yuam kev hauv cov hlab ntsha siab?

I. Tej yam ua yuam kev loj (Endangering Safety)
Cov kev ua yuam kev no tuaj yeem ua rau muaj kev nyab xeeb loj thiab muaj feem cuam tshuam kev lag luam loj:

1. Kev faib tawm tsis raug ntawm cov hlab ntsha siab, ua rau kev siv tsis raug ntawm cov qauv;

2. Kev ntsuas lub zog tsis raug lossis nruj rau qhov siab loj -cov kabmob (plhaub, taub hau, flanges, thiab lwm yam), nrog rau qhov sib txawv tseem ceeb ntawm cov duab kos thiab cov ntawv suav;

3. Kev xaiv cov khoom siv tsis raug rau lub siab loj- cov kabmob cov kabmob, ua tsis tau raws li qhov xav tau ntawm qhov nruab nrab, qhov siab, thiab qhov kub thiab txias, ib qho kev ua yuam kev;

4. Kev tso tseg lossis ua yuam kev hauv cov kev xav tau tseem ceeb, nrog rau qhov yuam kev hauv kev tsim qauv ntawm lub siab loj-cov kabmob.

II. General Technical yuam kev (Tshuaj muaj peev xwm)
Kev ua tsis tau raws li cov txheej txheem yuav ua rau muaj kev nyab xeeb lossis raug nqi pov tseg:

1. Cov qauv tsim tsis raug lossis raug tshem tawm, tsis raug txiav txim siab txog kev txiav txim siab ntawm cov hlab ntsha siab lossis faib lawv ntau dhau;

2. Kev xaiv tsis raug ntawm cov ntaub ntawv thiab cov qauv rau kev siab -cov kabmob, tsis raug lossis tshem tawm cov kev cai;

3. yuam kev los yog tsis ua hauj lwm nyob rau hauv lub zog xam, thiab yuam kev nyob rau hauv daim duab qhov ntev thiab cov ntaub ntawv annotation.

III. General Drawing yuam kev (Tshem Tawm Machining) Cov no tsis ua rau muaj kev nyab xeeb tab sis yuav cuam tshuam rau kev tsim khoom:

1. Tsis siv cov ntsuas ntsuas raws cai; siv cov ntawv tsis meej pem yooj yim (piv txwv li, i, j, l, o) rau cov yeeb nkab nozzle cov cim, uas tej zaum yuav tsis raug raws li cov lej;

2. Kev xaiv tsis tsim nyog ntawm lub hauv paus loj; muaj qhov kaw qhov ntev chains; omission / tsis raug annotation ntawm qhov chaw qhov ntev rau lub thawv khoom siv;

3. Kev xaiv tsis raug lossis raug tshem tawm ntawm kev ua siab ntev thiab roughness specifications; flange ntsia liaj qhov rooj qhov tsis npaj thoob plaws qhov chaw; tsis raug lossis tshem tawm cov yeeb nkab nozzle / kev txhawb nqa;

4. Cov duab kos duab thiab cov duab nthuav dav tsis ua raws li cov qauv tsim qauv; muaj cov ntawv nyeem yuam kev, linear yuam kev, thiab cov zauv feem tsis raug.
