Tom qab 10+ xyoo ntawm qhov chaw soj ntsuam thiab ntsuas ntsuas qhov teeb meem rau cov nroj tsuag tshuaj, refineries thiab cov chaw kho dej, kuv mam li hais qhov no ncaj qha: feem ntau cov hlau nplaum flapper gauge nyeem ntawv yuam kev tsis yog los ntawm lub faulty unit. Lawv los ntawm kev ua haujlwm tsis raws cai ntawm -- kev cob qhia ua haujlwm, kev coj cwj pwm tsis sib xws ntawm kev hloov pauv, thiab cov ntsiab lus me me uas txhua tus xav tias yog "kev nkag siab zoo."
Ib zaug kuv tau ua haujlwm nrog cov tshuaj cog qoob loo uas muaj cov kuab tshuaj me me dhau mus taug qab raws nraim qhov no. Ib qho kev ntiav tshiab tau nyeem hauv qab ntawm qhov dawb flapper seem es tsis txhob xim ciam teb, thiab underestimated qib los ntawm ze li ntawm 40mm. Qhov ntsuas tau ua haujlwm zoo kawg nkaus. Qhov yuam kev yog dawb huv ntawm qhov ntsuas tau txhais li cas.
Kev nyeem cov ntsuas no yooj yim ntawm ib saib, tab sis cov ntsiab lus xws li qhov yuam kev parallax, thaj chaw dig muag, daig flappers thiab misaligned xoom cov ntsiab lus tag nrho ntxiv rau cov teeb meem kev ua haujlwm tiag tiag - los ntawm kev hloov cov khoom muag suav rau twj kom qhuav -khiav kev puas tsuaj. Phau ntawv qhia no taug kev los ntawm kev nyeem ntawv kom raug, rhuav tshem cov hom teev ntau, thiab npog qhov yuam kev uas kuv pom feem ntau hauv thaj teb. Ua raws li cov txheej txheem no, thiab koj yuav tshem tawm yuav luag txhua tus tib neeg- ua rau kev nyeem ntawv yuam kev ntawm qhov chaw.
Ua ntej: Yuav Ua Li Cas Flapper Display Ua Haujlwm (thiab Vim Li Cas Qhov no Tseem Ceeb rau Kev Nyeem)
Ua ntej peb mus rau qhov ntsuas, nws tsim nyog los npog cov lus qhia yooj yim - tsis yog rau phau ntawv vim li cas, tab sis vim kev nkag siab yuam kev no yog lub hauv paus ntawm ib nrab ntawm cov cwj pwm tsis zoo nyob ntawd.
Magnetic flapper gaugeskhiav ntawm txoj kev sib txuas lus cov hlab ntsha. Ib ntsug bypass chamber mounts rau sab tank, yog li cov kua theem hauv chamber sib phim lub tank raws nraim. Lub tshuab nqus hlau nplaum sib khi caij rau ntawm cov kua dej sab hauv lub chamber, thiab thaum nws txav mus, nws cov hlau nplaum tau dhau los ntawm cov phab ntsa hlau thiab tig ib kab ntawm ob - xim flappers sab nraud.
Los ntawm kev lag luam thoob ntiaj teb cov rooj sib tham, flappers hauv qab cov kua dej tig ib xim (yuav luag ib txwm liab) thiab cov saum toj no nyob ib xim thib ob (dawb, nyiaj lossis dub). Txoj kab ntse qhov twg ob xim sib ntsib yog cov kua dej kiag li.
Nov yog txoj cai tsis yog -negotiable rule:koj nyeem cov xim ciam teb, tsis yog saum lossis hauv qab ntawm ib qho flapper. Kuv tau pom tag nrho cov kev hloov pauv tsis pom zoo rau qhov no, nrog rau hnub ua haujlwm nyeem sab saum toj ntawm thaj chaw liab thiab hmo ntuj hloov pauv hauv qab ntawm thaj chaw dawb - thiab xav tsis thoob vim li cas lawv cov lej hloov pauv tsis sib xws.
Kauj ruam-los ntawm-Kauj ruam: Yuav ua li cas thiaj ua tau qhov tseeb, kev nyeem ntawv zoo ib yam
Ua raws li cov txheej txheem no txhua zaus koj nyeem ntawv. Nws yuav siv sij hawm 10 vib nas this ntxiv, thiab tshem tawm 90% ntawm qhov yuam kev feem ntau.
1. Txheeb xyuas qhov ntsuas ntsuas thiab xoom siv ua ntej
Ua ntej koj txawm saib cov flappers, xyuas ob yam:
- Chav tsev: millimeters, centimeters, nti, taw, lossis feem pua? Imperial scales yog qhov yooj yim tshaj rau misread yog tias koj siv rau metric - tsis txhob ua txhaum rau decimal increments.
- Zero point: Nyob rau sab txheem-mount gauges, lub 0 cim ntawm lub teev yuav tsum kab nrog rau qhov nruab nrab ntawm cov txheej txheem qis flange, tsis yog hauv qab ntawm qhov taw qhia rail. Qhov no yog ib qho teeb meem feem ntau saib tsis taus ntawm cov khoom hloov pauv tom qab. Yog tias tus lej xoom raug kaw, txhua qhov kev nyeem ntawv los ntawm qhov ntsuas ntawd yuav ua tsis ncaj ncees los ntawm qhov kev sib tw. Kuv tau ntes tau qhov no tsawg kawg yog kaum ob lub vev xaib mus ntsib.
2. Nrhiav tus ciam teb xim xim
Kauj ruam rov qab thiab nrhiav txoj kab kab rov tav uas qis (kua) xim raws li cov xim sab saud (cua) xim. Rau cov qauv liab / dawb ntsuas:
- Khoom liab=kua- puv seem
- Khoom dawb=seem seem saum cov kua
- Qhov tseeb theem zaum ntawm ntug sab saum toj ntawm lub siab tshaj plaws liab flapper, uas kuj yog lub hauv qab ntug ntawm qhov qis tshaj dawb flapper.
Ntawm lub qhov dej- khaws cia qhov ntsuas no ob lub npoo kab zoo kawg nkaus. Yog tias koj pom 1-2 ib nrab xim flappers ntawm qhov kev hloov pauv, qhov ntawd yog qhov kev sib txhuam me me. Rau kev nyeem ntawv niaj hnub, siv qhov nruab nrab ntawm qhov kev hloov pauv ntawd.
3. Tau qhov muag theem kom tshem tawm qhov yuam kev parallax
Parallax yuam kev yog # 1 ua rau me me tab sis kev nyeem ntawv sib txawv ntawm cov neeg ua haujlwm. Yog tias koj sawv hauv qab theem thiab saib, tus ciam teb yuav zoo siab dua li qhov tiag tiag. Yog tias koj sawv saum toj thiab saib qis, nws yuav saib qis dua. Ntawm 4-meter tank, qhov yuam kev no tuaj yeem yooj yim ntaus 20–30mm - txaus los pov tawm cov khoom lag luam suav lossis ua rau lub tswb cuav.
Kev kho yog yooj yim:
- Tso koj tus kheej kom koj ob lub qhov muag nyob nrog cov xim ciam teb.
- Ntawm cov tso tsheb hlau luam siab, siv lub platform nkag mus rau ntawm qhov siab zoo es tsis txhob nyeem hauv av.
- Rau kev tshawb xyuas ceev ceev uas koj tsis tuaj yeem ncav cuag qhov muag, tsuas yog paub qhov kev nyeem ntawv yuav qis me ntsis los ntawm theem hauv av, thiab tsis txhob kho nws raws li qhov ntsuas qhov tseeb.
4. Siv cov ntawv nyeem thiab hla - xyuas yog tias xav tau
Nyeem tus nqi ntawm qhov ntsuas raws nraim nrog cov xim ciam teb. Rau metric centimeter nplai, koj tuaj yeem ntseeg tau kwv yees rau qhov ze tshaj plaws millimeter. Rau qhov ntsuas feem pua, nyeem rau qhov ze tshaj plaws feem pua.
Yog tias koj tseem muaj 4-20mA transmitter ntawm tib lub ntsuas thiab cov lej tsis sib xws, tsis txhob cia siab tias qhov ntsuas ntsuas tsis raug. Feem ntau qhov tsis sib haum yog los ntawm kev teeb tsa ntau yam tsis raug hauv qhov kev tswj hwm, tsis yog lub ntsej muag flapper. Nco ntsoov xyuas kom meej tias lub transmitter 0% thiab 100% cov ntsiab lus tau teem rau tib lub flange references raws li cov neeg kho tshuab nplai.
4 Hom Scale Hom thiab Yuav Nyeem Li Cas
Tsis yog txhua qhov ntsuas tau cim ib yam nkaus. Nov yog yuav ua li cas thiaj lis plaub hom koj yuav pom ntau zaus hauv thaj teb.
Metric nplai (mm / cm / m)
Cov txheej txheem kev lag luam thoob ntiaj teb. Feem ntau yog cim nyob rau hauv centimeters nrog millimeter zuam cim, nrog 0 nyob rau hauv qis flange thiab qhov tseem ceeb nce siab.
- Feem ntau siv cov ntaub ntawv: cov txheej txheem dav dav tank, dej cia, tshuaj cia
- Pro cov lus qhia: suav cov zuam me ntawm cov lej centimeter cim - txhua tus yog 1 hli.
Imperial nplai (inch / taw)
Feem ntau muaj nyob rau hauv North American cov chaw thiab US - qauv export tej yaam num. Tej zaum lawv yuav raug cim hauv ntiv tes nkaus xwb, lossis hauv ko taw thiab ntiv tes.
- Qhov teeb meem tseem ceeb: 1 ko taw=12 ntiv tes, tsis yog 10. Kev nyeem 3.5 ko taw li 3 taw 5 ntiv tes yog qhov yuam kev heev rau cov neeg siv los ntsuas. Ntawm lub tank loj loj, qhov yuam kev ntawd tuaj yeem ntxiv txog ntau pua nkas loos ntawm cov khoom muag tsis sib xws.
- Feem ntau siv cov ntaub ntawv: refineries, roj terminals, US - qauv txheej txheem tanks
Qhov ntsuas feem pua (0-100%)
Qhov feem pua ntawm cov nplai qhia cov txheeb ze sau, tsis yog qhov siab kawg . 0%=khoob ntawm qhov flange qis, 100%=puv ntawm flange sab saud.
- Cov lus ceeb toom tseem ceeb: 100% ntawm qhov ntsuas txhais tau tias ntsuas tag nrho, tsis yog tag nrho lub tank ntim. Muaj ib txwm ib qho me me ntawm qhov muag tsis pom thaj tsam saum lub flange sab saud, yog li lub tank tuaj yeem tuav cov kua me me dua li 100% cim.
- Feem ntau siv cov ntaub ntawv: batch txheej txheem tso tsheb hlau luam, dosing tank, qhov twg cov txheeb ze sau tseem ceeb tshaj qhov siab
Custom engineered scale ( ntim / loj)
Rau qhov ruaj khov - qhov ntev tanks, cov nplai tuaj yeem raug kho kom haum kom pom cov ntim ncaj qha (liters, gallons, cubic meters) lossis loj (tons, kilograms) es tsis txhob qhov siab. Cov nqi yog ua ntej- xam raws li tank cross-section thiab nruab nrab ntom.
- Cov txiaj ntsig loj: tshem tawm cov kev suav ntawm phau ntawv yuam kev thaum kuaj cov khoom muag
- Feem ntau siv cov ntaub ntawv: bulk cia tso tsheb hlau luam, cov khoom tiav tso tsheb hlau luam, cov khoom siv tswj cov tank
6 Qhov Kev Nyeem Ntawv Tsis Muaj Feem Ntau Kuv Pom Ntawm -Site
Cov no yog qhov ua yuam kev uas kuv tau ua dhau los thaum lub sijhawm tshawb xyuas qhov chaw. Yuav luag txhua tsob nroj muaj tsawg kawg yog ib tus neeg ua haujlwm ua ob lossis ntau dua ntawm cov no.
1. Tsis nco qab qhov chaw dig muag sab saud thiab sab qis
Txhua qhov sib nqus flapper gauge muaj ib qho chaw dig muag me me rau saum thiab hauv qab, los ntawm lub cev qhov siab ntawm ntab. Thaum lub ntab tsoo nws lub hauv qab nres, tseem muaj cov kua hauv qab nws - feem ntau 20–40mm, nyob ntawm qhov loj me.
Ib qho kev ntsuas kom raug ntsuas qhov 0 cim twb tso nyiaj rau thaj tsam qis qhov muag tsis pom thiab ua raws li qhov chaw flange qis. Tab sis yog tias qhov ntsuas tau hloov pauv ntawm qhov chaw yam tsis muaj kev rov ntsuas dua, qhov xoom taw tes tuaj yeem ua rau txoj kev tawm.
Tiag -kev cuam tshuam hauv ntiaj teb: Yog tias koj nyeem 0 thiab xav tias lub tank yog tag nrho, koj tseem tuaj yeem muaj 30+ hli ntawm cov kua sab laug. Qhov ntawd yog ib qho ua rau lub twj tso kua mis qhuav - khiav kev puas tsuaj thaum lub tank ntws.
2. Kev nyeem ntawv ntawm ntug xim tsis raug
Qee tus neeg ua haujlwm ib txwm nyeem sab saum toj ntawm thaj chaw dawb, lwm tus nyeem hauv qab ntawm thaj chaw liab. Ntawm qhov ntsuas ua haujlwm zoo kawg nkaus qhov no ua rau tsis muaj qhov sib txawv, tab sis thaum flappers tau daig me ntsis lossis tsis zoo, qhov sib txawv tuaj yeem yog 10-20mm.
Kev coj ua kev lag luam tus qauv yog nyeem cov ntug sab saum toj ntawm cov kua -xim (yuav luag ib txwm liab) ntu. Sau qhov no rau hauv koj qhov chaw txheej txheem kom txhua qhov kev hloov pauv siv tib txoj cai.
3. Tsis quav ntsej parallax ntawm lub tank siab

4. Kho cov nyees khawm flappers raws li qib ruaj khov
Flappers tuaj yeem daig los ntawm kev thauj mus los, muaj zog sab nraud sib nqus cuam tshuam, lossis kev sib kis me me. Thaum lawv khov, cov zaub yuav nyob twj ywm txawm tias qhov tseeb theem hloov.
- Kev Ceeb Toom: Cov qib nyeem ntawv nyob twj ywm tsis hloov pauv thaum sau lossis tso dej, thaum koj paub tias nws yuav tsum txav mus.
- Kev sim ceev: Khiav ib lub hlau nplaum ruaj khov maj mam nyob rau sab nraud ntawm qhov taw qhia rail. Yog tias cov flappers rov pib dua thiab ciam teb dhia mus rau txoj haujlwm tshiab, koj qhov kev nyeem ntawv yav dhau los tau daig, tsis yog tiag.
5. Kev ntsuas tsis meej pem nrog tag nrho lub tank qhov siab
Qhov ntsuas tsuas yog npog qhov kev ncua deb ntawm cov txheej txheem sab sauv thiab qis flanges. Nws tsis suav nrog qhov chaw saum lub flange sab saud, lossis ib qho conical tank hauv qab hauv qab flange.
- Piv txwv tias 100% scale=tag nrho lub tank yog ib qho kev pheej hmoo overfill classic. Nco ntsoov paub meej tias lub tank qhov ntim tag nrho tawm tsam qhov ntsuas qhov ntsuas 100% siv.
6. Hmo ntuj nyeem nrog lub kaum ntse ntse teeb pom kev zoo
Kev nyeem ntawv hmo ntuj nrog lub teeb nyem tuav ntawm lub kaum sab xis tsim cov duab ntxoov ntxoo uas ua rau cov xim ciam teb nyuaj kom nrhiav tau qhov tseeb.
- Txoj kev kom raug: Tuav lub teeb nyem ncaj qha rau pem hauv ntej ntawm qhov taw qhia, sib npaug rau qhov ntsuas, kom pom cov flappers sib npaug.
- Rau cov chaw uas nquag mus xyuas hmo ntuj, ci -nyob rau hauv- lub - tsaus nti nplai strips los yog ua - nyob rau hauv LED taw qhia rails tshem tawm cov teeb meem no tag nrho.
Kev daws teeb meem ceev: Yog tias koj nyeem ntawv tsis raug
Yog tias qhov kev nyeem ntawv tsis zoo li qhov koj xav tau, tsis txhob hu tam sim rau kev pabcuam ntsuas. Khiav peb qhov kev kuaj xyuas sai ua ntej - Kuv xav hais tias 80% ntawm "faulty gauge" hu tau txais kev daws teeb meem ntawm qhov chaw nrog qhov niaj hnub no.
Ua ntej: Pib dua cov flappers
Khiav ib tug handheld hlau nplaum raws li tag nrho ntev ntawm qhov taw qhia rail los ntawm sab saum toj mus rau hauv qab. Qhov no yuav realign tag nrho cov flappers kom phim qhov tseeb ntab txoj hauj lwm.
Yog tias ciam teb txav mus thiab tom qab ntawd nyob twj ywm, qhov teeb meem tsuas yog daig flappers, tsis yog qhov txhaum loj dua.
Yog tias tag nrho cov seem ntawm flappers tsis txav txhua, lub ntab yog zaum hauv lub chamber, los yog poob nws cov hlau nplaum.
Thib ob: Txheeb xyuas qhov zero siv
Txheeb xyuas tias 0 cim ntawm cov kab ntsuas nrog rau qhov nruab nrab ntawm cov txheej txheem qis flange. Yog tias nws tsis yog, qhov ntsuas tau hloov pauv lossis raug teeb tsa tsis raug. Koj tuaj yeem hloov qhov ntsuas qhov ntsuas, lossis siv qhov kev daws teeb meem rau txhua qhov kev nyeem.
Thib peb: Hla- xyuas nrog lub ntim paub
Yog tias koj tseem xav tias qhov tsis raug, ntxiv cov kua uas paub txog rau hauv lub tank thiab saib seb qib nce los ntawm cov nyiaj tau los. Ntawm cov tso tsheb hlau luam me, txawm tias qhov sib ntxiv 50-liter yuav qhia qhov tseeb, ntsuas qhov ntsuas ntawm qhov ntsuas.
Yog tias qhov kev nyeem ntawv sib npaug ntawm kev suav, qhov ntsuas thiab ntsuas qhov tseeb yog - qhov tsis sib xws yog nyob rau hauv koj qhov kev cia siab.
Yog tias nws tsis sib xws, lub ntab yuav yog qhov tsis ncaj ncees rau qhov nruab nrab, lossis muaj qhov thaiv hauv cov kav dej hauv chamber.
Cov cwj pwm yooj yim kom nyeem ntawv tsis tu ncua hla kev ua haujlwm
Koj tsis xav tau cov cuab yeej zoo nkauj los khaws cov ntawv nyeem kom ntseeg tau. Ob peb tus cwj pwm ntawm qhov chaw yooj yim yuav tshem tawm yuav luag txhua qhov hloov pauv - mus rau - hloov tsis sib xws:
- Standardize txoj cai nyeem ntawv nyob rau hauv kev sau ntawv. Muab txoj cai "nyeem sab saum toj ntawm cheeb tsam liab" hauv koj cov txheej txheem ua haujlwm, thiab cob qhia txhua tus neeg ua haujlwm rau tib tus qauv. Qhov no ib leeg kho feem ntau qhov sib txawv ntawm kev xa khoom.
- Kos qhov chaw qhov muag tsis pom ntawm qhov ntsuas. Ntxiv ib daim ntawv me me rau ntawm qhov taw qhia uas qhia thaj tsam sab sauv thiab qis qis, yog li tsis muaj leej twg puas tau kho 0% li khoob kiag li.
- Pib dua flappers tom qab kho. Txhua lub sij hawm qhov ntsuas tau txais kev pab, lub tank yog drained, los yog muaj kev co hnyav los ntawm cov khoom nyob ze, khiav ib tug reset hlau nplaum raws txoj kev tsheb ciav hlau kom tshem tawm misaligned flappers.
- Hla- kuaj xyuas peb lub hlis twg. Sib piv cov ntsuas ntsuas kev nyeem ntawv tawm tsam cov chaw taws teeb xa tawm lossis phau ntawv qhia dipstick ib zaug hauv ib lub hlis twg kom ntes cov nplai drift thaum ntxov.
Cov lus nug nquag
Cov no yog cov lus nug uas kuv tau nug ntau zaus thaum lub sijhawm kev cob qhia tus neeg ua haujlwm thiab kev tshuaj xyuas qhov chaw.
Qhov twg raws nraim koj nyeem kab ntawm lub ntsuas magnetic?
Koj nyeem tus nqi ntawm cov nplai uas kab nrog cov ciaj ciam ntse ntawm ob lub flapper xim. Rau standard liab / dawb gauges, uas txhais tau hais tias lub sab saum toj ntug ntawm lub siab tshaj plaws liab flapper. Nco ntsoov khaws koj ob lub qhov muag nrog ciam teb kom tsis txhob muaj qhov yuam kev parallax.
Koj puas nyeem sab saum toj lossis hauv qab ntawm ntu liab?
Nyeem rau sab saum toj ntawm ntu liab. Cov flappers liab sib haum rau cov kua - puv ib feem ntawm lub chamber, yog li lub siab tshaj plaws liab flapper cim cov kua dej. Qhov no yog tus qauv kev lag luam convention.
Vim li cas kuv lub ntsuas ntsuas magnetic nyeem tsis raug?
Feem ntau cov ntawv nyeem tsis raug yog los ntawm peb qhov teeb meem: misaligned xoom taw tes ntawm qhov ntsuas, parallax yuam kev los ntawm saib lub kaum sab xis, lossis daig flappers. Khiav qhov pib dua thiab xoom kos ua ntej ua ntej xav tias qhov ntsuas nws tus kheej yog qhov tsis raug.
Vim li cas thiaj muaj qhov sib txawv los yog sib cais hauv kuv cov khoom sib nqus flapper?
Qhov sib txawv me me ntawm 1-2 flappers yog qhov kev sib txhuam me me, thiab tuaj yeem kho nrog cov hlau nplaum sab nraud rov pib dua. Qhov sib txawv loj dua txhais tau hais tias lub ntab yog daig, tau poob lub zog sib nqus, lossis yog dab dej vim qhov tsis ncaj ncees lawm qhov loj me - qhov no xav tau kev tshuaj xyuas ntxiv.
Kuv puas tuaj yeem hloov qhov ntsuas ntawm kuv qhov ntsuas magnetic tam sim no?
Yog lawm. Feem ntau cov nplai strips mount nyob rau hauv ib lub channel los yog nrog cov nplaum, thiab tuaj yeem hloov tau. Koj tuaj yeem hloov cov ntsuas ntsuas nrog imperial, ntxiv cov cim feem pua, lossis xaj cov ntim kev cai -calibrated scale kom phim koj lub tank qhov ntev.
Kev xav zaum kawg
Kev nyeem ntawv qib magnetic flapper ntsuas tsis yog qhov nyuaj, tab sis nws muaj ntau nuanced ntau dua li cov nroj tsuag xav. Feem ntau ntawm kev nyeem ntawv tsis sib xws tsis yog cov cuab yeej ua tsis tiav - lawv yog tib neeg yuam kev los ntawm cov txheej txheem tsis sib xws, tsis nco qab qhov muag tsis pom kev, thiab tsis raug kho parallax.
