Ib Leeg -} txaus meters, raws li cov cuab yeej tseem ceeb hauv kev ua kom saib xyuas cov kua dej, roj av rau dej, roj av, thiab lwm yam khoom siv Industrial. Qhov zoo ntawm lawv cov teeb tsa ncaj qha cuam tshuam cov kev ntsuas qhov tseeb, txoj kev ntseeg tau, thiab kev ua haujlwm tom ntej ua tau zoo. Raws li cov qauv kev lag luam thiab cov kev ua haujlwm engineering
I. Ua ntej -}} xob npaj npaj
1. Ib puag ncig thiab kev ua haujlwm ntsuas
Ua ntej kev teeb tsa, ib qho kev ua haujlwm tiag tiag ntawm kev ua haujlwm ntawm lub raj (piv txwv li cov roj ntsha, thiab lwm yam), nrog rau kev siv hluav taws xob (xws li} pa) (Hlau, PVC, Stainless Hlau, thiab lwm yam). Tsis tas li ntawd, kev teeb tsa ib puag ncig yuav tsum tau soj ntsuam kom muaj zog hauv hluav taws xob hluav taws xob, kev co, lossis cov roj corrosive. Kev tiv thaiv, kev co kom nruj, thiab kev ntsuas xeb yuav tsum tau ua raws li qhov tsim nyog.
2. Kev xaiv khoom siv thiab kev txheeb xyuas
Xaiv ib qho haum nkaus xwb - me me 'thiab cov yeeb yaj kiab uas muaj ntau yam (DNAINTIONS), thiab cov mem tes uas muaj (RS485, thiab lwm yam). Thaum tuaj txog, txheeb xyuas cov khoom siv cov lus qhia tshwj xeeb (xws li qhov tseeb ntawm ± 0.5% rau cov ntawv thov tshwj xeeb xws li ERO 9001 thiab cim CE). Ua cov xoom tso tshuaj calibration thiab ncua kev pov thawj siv cov kev plees txaus kom ntseeg tau tias yuav tsum ua cov kev ua tau zoo.
3. Cov Cuab Yeej thiab Khoom Npaj
Cov cuab yeej muaj xws li cov yeeb nkab cutter (rau cov yeeb nkab hlau), ib qho hluav taws xob sib tsoo), kom tswj tau cov khaub noom ( Cov ntaub ntawv khaws cia suav nrog cov roj av sib dhos (xws li cov roj hmab sib txuas rau cov roj), ua kom muaj fluoring ntau dua li 8.8), thiab cov xaim hluav taws xob (rau cov xov hluav taws xob (rau cov xaim hluav taws xob (rau cov xaim hluav taws xob (rau cov xaim hluav taws xob (rau cov xov hluav taws xob (rau cov xaim hluav taws xob (rau cov xaim hluav taws xob (rau cov xaim hluav taws xob (rau hluav taws xob xaim hluav taws xob (rau hluav taws xob xaim hluav taws xob (rau hluav taws xob xaim hluav taws xob (rau cov xov hluav taws xob (rau cov xov hluav taws xob (rau cov xov hluav taws xob (rau cov xaim hluav taws xob
Ii. Txheej Txheem Txheej Txheem thiab Cov Ntsiab Lus Tseem Ceeb
1. Kev xaiv qhov chaw xaiv
Ib Leeg -} Flers meters yuav tsum tau muab ntsia hauv cov kab kab rov tav, kom deb ntawm cov roj ntsha li cuab tam xws li tshob, li qub, thiab tees. (Cov seem seem yuav tsum muaj ntau dua los yog sib npaug ntawm cov kab mob taub hau, thiab muab cov pa tawm hauv qab los tiv thaiv cov pa npuas kom tiv thaiv. Thaum muab cov kab rov tav, cov electrode lub cev yuav tsum tau ua kom tig mus rau hauv av kom tiv thaiv sediment los ntawm npog cov electrodes.
2. Cov pipeline pretricatment
Close ntws thiab dej ntws tsag rau cov dej seem los ntawm cov raj hluav taws xob uas seem ntawm cov raj dej (cov kua yuav tsum tau nqus huab cua, thiab cov roj yuav tsum tau tiv thaiv los ntawm cov dej paug). Siv lub kaum ntse ntse los yog scraper kom tshem tawm xeb, thiab tawg ntawm cov kab sib txuas yog qhov kawg thiab tsis muaj kev sib luag dua lossis sib npaug rau 3.2μm). Rau cov kav dej uas nruab tau tshiab, nws pom zoo kom yaug (rau cov dej (rau roj (rau roj ntsuas kom tiv thaiv kom tsis txhob muaj kev cuam tshuam rau sab hauv.
3. Meter lub cev installation thiab kev nyab xeeb
• Flange kev txuas: Dlhos lub cev lub cev flange nrog cov yeeb nkab flange (sib txawv tsawg dua lossis sib npaug nrog 0.5 hli). Ntxig cov khoom sib txuas thiab zawm lawv symmetrically (hauv cov qauv bisscretically; xa mus rau cov chaw tsim khoom cov lus qhia zaum kawg, feem ntau 40-60 n·). Nco ntsoov tias lub cev meter lub cev yog confulric nrog cov yeeb nkab (qhov sib txawv tuaj yeem tshawb xyuas cov kev sib tw siv tau yooj yim).
• Xov xwm txuas: qhwv ib tus nqi tsim nyog ntawm teflon daim kab xev nyob ib ncig ntawm cov yeeb nkab xov (moos). Tom qab screwing lub cev meter lub cev rau hauv cov yeeb nkab kom txog thaum nws hu rau cov ciaj ciam chaw, ua kom nruj nrog lub zog uas muaj cai (feem ntau 20-30 n· m). Zam kev quab yuam ntau dhau uas yuav ua rau muaj kev deformation ntawm kev sib khi saum npoo.
• Clamp -} On type (rau me me diame (rau meter lub cev rau hauv cov yeeb nkab lub nplhaib thiab ua kom nruj nrog bolts (torque 15-25 n· m). Xyuas kom lub zog clamping yog felly faib rau kev tiv thaiv lub cev meter lub cev los ntawm tilting.
4. Kev sib khi thiab hluav taws xob sib txuas
Tom qab kev teeb tsa, thov cov dej xab npum rau txhua qhov chaw sib txuas (flanges, xov, thiab ntsuas cov pa npuas yog suav tias yog huab cua npuas raug suav tias yog siv tau). Thaum xaim, kom ntseeg tau zoo thiab tsis zoo raws li kev txiav txim siab (mem tes ntawm 4 {- 20ma teeb liab yuav tsum tau cog rau ib qho kawg). Xyuas kom meej tias cov hlau hla-seem yog ntau dua los yog sib npaug rau 1.5 mm² thiab khiav los ntawm Conduit los tiv thaiv kev puas tsuaj rau kev puas tsuaj thiab noo noo. Lub davhlau ya nyob twg yuav tsum sib txuas nrog rau cov yeeb nkab hauv av (hauv av tsis kam dua lossis sib npaug) los tiv thaiv kev ntsuas tsis yog los ntawm kev cuam tshuam hluav taws xob.
III. Commissioning thiab kev lees txais
1. Thaum Pib Txheej Txheem
Maj mam qhib lub nce toj li valve kom paub qhov nruab nrab. Saib lub ntsuas lub cev tso pa tawm (yog tias nruab) kom tshem tawm cov pa roj thiab tsis muaj cov tee dej yuav tsum tau muab tshem tawm rau cov roj av). Tom qab paub tseeb tias tsis muaj xau, maj mam qhib lub valve mus rau tus nqi ntws ib txwm.
2. Kev ntsuas chaw thiab ntsuas hluav taws xob
Nkag mus rau nruab nrab tsis (piv txwv li, dej ceev 1000 kg / mg, ntuj hloov chaw ua haujlwm, thiab lwm yam) siv cov chaw nres tsheb handheld lossis chaw deb. Kho qhov ntau ntawm qhov ntau raws li qhov tseeb txaus (yog tias lub- lub vev xaib txaus los ntawm ntau dua ± 3%, kev rov ntsuas dua). Tom qab muaj kev tiv thaiv, kos tias cov zaub (lossis cov zis tawm) qhia txog cov nqi ruaj khov (kev hloov kho ntawm tsawg dua lossis sib npaug ntawm 1% yog suav tias yog ib txwm).
3. Kev lees paub cov qauv
Qhov kev lees paub zaum kawg yuav tsum muaj hauv qab no: ① Flow qhia yuam kev yog nyob rau hauv cov khw ntsuas qhov tseeb (piv txwv li, ± 1%); Tsis muaj cov xaim, txawv txav, lossis suab nrov; ③ Qhov chaw ntsuas teeb liab ruaj khov (qhov sib txawv ntawm cov ntaub ntawv tswj cov chaw taws teeb thiab ntsuas lub cev tso tawm tsawg dua lossis sib npaug rau 0.5%); Tag nrho cov fasteners muaj kev ruaj ntseg thiab ntsaws ruaj ruaj qhia cov cim ntawm kev laus.
IV. Cov Lus Qhia Kev Saib Xyuas thiab Kev Txij Nkawm Cov Lus Qhia
• Cov lus ceeb toom kev nyab xeeb: kev teeb tsa muaj feem cuam tshuam nrog siab {0} kub (xws li muaj cov pa hluav taws xob (xws li muaj kev kub ntxhov - tawm valve.
• Txwv tsis pub cov scenarios: Thaum cov xov xwm muaj ntau cov khoom me me (xws li slurry) lossis npuas nrog lub ntim sib piv ntau dua 5%, lim lossis degasser yuav tsum tau nruab. Ua tsis tiav yuav ua rau lub ntsej muag muag lossis ntsuas tsis ua haujlwm.
• Ntev ntev - sij hawm tu: Khij qhov xwm txheej ntawm lub hlis (yog hais tias kev laus ib xyoos (yog hais tias kev laus ib xyoos (yog hais tias kev laus ib xyoos (yog hais tias kev laus ib xyoos (siv lub thawv tshav ntuj), hloov lub thawv sunhade lossis tiv thaiv zoo li sab nraum zoov).
Tag
Kev tsim kho kom raug ntawm ib qho - Flowes yog qhov tseem ceeb rau kev ua haujlwm txhim khu kev qha ntawm kev ua kua ntsuas. Cov kws tshaj lij yuav tsum ua raws li cov txheej txheem kev ua haujlwm tag nrho ntawm tag nrho cov txheej txheem, suav nrog kev xaiv kev ua haujlwm, cov txheej txheem kev siv khoom, thiab kev lees txais. Kev xaiv zoo raws li cov chaw xaiv tiag tiag (kev siv hluav taws xob tshwj xeeb, muab cov ntsuas hluav taws xob tshwj xeeb, muab cov tshuaj tiv thaiv ncaj ncees, thiab kev saib xyuas hluav taws xob, thiab kev saib xyuas kev nyab xeeb.
