I. Qhia meej txog cov haujlwm tseem ceeb hauv kev ua ntej
1. Nkag siab cov yam ntxwv ntawm Media: Paub meej tias qhov loj me me, corrosiveness, viscosity, kub, thiab muaj fibrous impurities nyob rau hauv nruab nrab yog pauv. Qhov no yog qhov tseem ceeb rau kev sib piv cov khoom siv lub cev lub cev thiab ntws - los ntawm cov khoom.
2. Txhais qhov kev ua tau zoo ciam teb: Kom meej meej qhov tseeb qhov yuav tsum tau ntws tus nqi thiab lub taub hau. Flow redundancy yuav tsum tswj tsis pub dhau 20%-80% ntawm tus nqi txaus txaus kom tsis txhob ncua sij hawm qis- thauj khoom lossis ua haujlwm puv.
3. Paub meej tias yuav tsum muaj tshwj xeeb: Tshawb xyuas ua ntej seb puas muaj tej yam tshwj xeeb xws li tawg- pov thawj, tsis muaj dej, siab - qhov kub thiab txias, los yog txwv qhov chaw yuav tsum tau ua kom tsis txhob muaj cov khoom tsis haum rau qhov chaw ib puag ncig.
II. Qhov tseem ceeb pitfalls kom tsis txhob thaum lub sij hawm xaiv qauv
1. Tsis txhob Parameter Overstatement: Tsis txhob blindly xaiv cov qauv uas tsis muaj ntau tshaj qhov xav tau tiag tiag. Ntau dhau inflated txaus tus nqi thiab lub taub hau tsis tsuas yog ua rau kom tus nqi yuav khoom tab sis kuj txo qhov kev xa khoom thiab ua kom cov nqi ua haujlwm tsis ua haujlwm.
2. Ua ntej sib piv rau qhov tsim nyog: Cov twj tso kua mis sib txawv muaj thaj tsam ntawm daim ntawv thov. Piv txwv li, cov twj pneumatic diaphragm yog nyiam rau kev xa tawm cov xov xwm corrosive uas muaj cov khoom, thaum cov twj tso kua mis ib leeg yog nyiam rau kev xa khoom siab - viscosity sludge. Qhov no zam cov twj tso kua mis tsis meej thiab xaiv cov khoom siv tsis raug.
3. Txheeb xyuas cov khoom sib xws: Paub meej cov ntaub ntawv ntawm cov khoom tseem ceeb xws li lub twj tso kua mis lub cev, cov ntsaws ruaj ruaj, thiab diaphragm raws li cov khoom siv xov xwm. Piv txwv li, fluoropolymer- cov twj tso kua mis yuav tsum muaj rau cov xov xwm corrosive, thaum siab -chromium alloy twj yog xav tau rau cov xov xwm abrasive heev.
III. Supplier thiab Contract Control
1. Xaiv Cov Neeg Siv Khoom Zoo: Ua ntej cov tuam txhab muaj npe nrov nrog ntau xyoo dhau los hauv kev lag luam thiab cov ntaub ntawv siv tau raws li kev ua haujlwm zoo sib xws. Zam tsis pub tsawg- cov khoom raug nqi los ntawm cov chaw tsim khoom me me uas tsis tsim nyog, vim tias cov khoom no muaj lub neej tsuas yog ib qho - thib peb ntawm cov khoom muaj npe nrov.
2. Paub meej tag nrho- Kev Pabcuam Zej Zog: Xav kom cov neeg muag khoom muab cov kev pabcuam thoob plaws hauv tag nrho cov txheej txheem, suav nrog ua ntej- kev sib tham txog kev muag khoom ntawm kev ua haujlwm thiab xaiv cov lus qhia, kev tsim cov kev nce qib hauv kev muag khoom, thiab tom qab- muag kev teeb tsa thiab kev taw qhia, cov khoom seem, thiab kev tshuaj xyuas tsis tu ncua.
3. Kos npe rau daim ntawv cog lus tus qauv: Qhia kom meej meej cov ntsiab lus ua tiav, cov qauv khoom siv, lub sij hawm lav, thiab tom qab -muag kev pab cuam lub sij hawm ntawm cov khoom hauv daim ntawv cog lus kom tsis txhob muaj kev tsis sib haum xeeb tom qab.
IV. Nce qib - xaiv pov thawj theem
1. Thov kom tus neeg muag khoom muab cov ntaub ntawv ua haujlwm tiag tiag thiab cov ntaub ntawv tshawb fawb ntawm cov neeg siv khoom raws li tib yam kev ua haujlwm los txheeb xyuas qhov ntev - lub sijhawm ruaj khov ntawm tus qauv xaiv.
2. Ua haujlwm me me -batch sim lossis thov kev sim ua haujlwm kom paub meej tias cov khoom siv ntws, lub taub hau, lub suab nrov, thiab lwm yam ntsuas tau ua tau raws li qhov yuav tsum tau ua ua ntej yuav ntau.
