Yuav Siv Lub Flow Meter li cas: Cov Lus Qhia Tseem Ceeb rau Kev Ntsuas Cov Kua Dej, Roj, thiab Chav Dej

Nyob rau niaj hnub no cov txheej txheem kev lag luam, lub ntab meter yog qhov ntsuas qhov ntsuas qhov tseeb. Nws yog siv los ntsuas tus nqi linear lossis nonlinear huab hwm coj float nqi thiab volumetric drift nqi ntawm cov kua, gases, los yog chav, precisely xam tag nrho qhov nruab nrab ntawm qhov nruab nrab mus txog ib tug pipeline ib chav tsev lub sij hawm. Txawm hais tias nyob rau hauv cov tshuaj, lub zog, ib puag ncig, lossis zaub mov thiab kev lag luam tshuaj, kev siv cov glide meters yog qhov tseem ceeb los ua kom muaj kev tiv thaiv kev tsim hluav taws xob thiab ua kom muaj hluav taws xob zoo.

I. Cov Ntsiab Cai

Flow meters xam cov nqi ntab los ntawm kev ntsuas qhov kev mus nrog qhov nrawm nrawm, qhov sib txawv ntawm qhov sib txawv, lossis qhov sib txawv ntawm lub cev ntawm cov kua dej hauv ib qho kev hla -section. Cov hom muaj xws li:

Differential Pressure Flow Meter: Kev ntsuas mus nrog tus nqi ntws los ntawm kev siv qhov sib txawv ntawm qhov sib txawv tsim tawm thaum cov kua dej dhau los ntawm lub tshuab kaw lus;

Electromagnetic Flow Meter: Raws li Faraday txoj cai ntawm electromagnetic induction, tsim nyog rau cov kua dej conductive;

Vortex Flow Meter: Ntsuas tus nqi waft los ntawm kev kuaj xyuas qhov zaus ntawm eddies generated tom qab cov kua dhau ntawm ib sab;

Mass Flow Meter (Coriolis Txoj Cai): Ncaj qha ntsuas cov huab hwm coj mus nrog tus nqi ntws ntawm cov kua;

Ultrasonic Flow Meter: Xam mus nrog qhov khiav nrawm los ntawm kev siv lub sijhawm sib txawv ntawm lub suab yoj tawm hauv cov kua.

Ua ntej txiav txim siab ntawm hom drift meter, nws yog qhov tseem ceeb kom paub meej qhov zoo ntawm qhov nruab nrab (conductivity, kub, siab, viscosity, thiab lwm yam) thiab teeb tsa.

II. Flow Meter Installation Cov kauj ruam

Installation Qhov Chaw Xaiv:

Zam cov chaw uas ua rau muaj kev cuam tshuam glide, xws li lub luj tshib, li qub, thiab lub twj tso kua mis;

Xyuas kom meej tias cov kav dej ntws thiab cov dej ntws ncaj nraim ntev raws li cov neeg tsim khoom xav tau;

Thaum muab tso rau hauv vertically lossis horizontally, chav kawm waft yuav tsum tsis tu ncua nrog cov xub qhia.

Environmental Requirements:

Tsis txhob muaj cov hlau nplaum muaj zog, kev cuam tshuam ntawm electromagnetic, kev co, lossis qhov kub thiab txias

kev hloov pauv;

Khaws cov yeeb nkab kom du thiab qhuav kom tsis txhob muaj av thiab ya raws los ntawm kev cuam tshuam cov khoom siv digital.

Cov xwm txheej yeeb nkab:

Xyuas kom cov phab ntsa sab hauv yog yooj yim thiab tsis muaj xeb los yog deposits;

Rau electromagnetic drift meters, cov yeeb nkab yuav tsum tau ntim cov kua kiag li.

III. Flow Meter Kev khiav hauj lwm thiab kev siv cov kauj ruam

Ua ntej -Pib Tshawb Xyuas

Xyuas kom pom tias cov khoom siv hluav taws xob, cables, hauv av, thiab cov kab kos npe sib txuas yog raug;

Paub meej tias lub koob meej ntawm lub valve thiab cov kua dej kub thiab lim yog nyob rau hauv qhov kev tso cai.

System Start -up

Maj mam qhib cov kua li qub kom tsis txhob muaj kev cuam tshuam tsis zoo;

Saib xyuas seb qhov glide nkhaus puas ruaj ntseg thiab seb qhov xoom - taw tes glide yog qhov qub.

Kev Ua Haujlwm Saib Xyuas

Tsis tu ncua cov ntaub ntawv ntws, siab, thiab kub qhov tseeb thiab tsom xam cov tiam sis;

Yog tias pom muaj kev hloov pauv lossis kev nyeem ntawv txawv, kuaj xyuas qhov hassle tam sim ntawd.

IV. Tsis tu ncua Calibration thiab tu

Qhov tseeb ntawm glide meters sib txawv nrog lub sijhawm thiab chaw ua haujlwm, yog li kev ntsuas txhua hnub yog qhov tseem ceeb.

Cov tswv yim calibration uas muaj xws li:

Standard Flow Device Comparison Method: Sib piv siv cov khoom siv siab -precision nrov;

Cov txheej txheem zoo li qub: Tsim nyog rau kev kuaj ntsuas cov kua mus nrog cov ntsuas ntsuas;

Online Calibration: Dynamic kho qhov kev siv ntawm calibration nkhaus.

Maintenance Focus:

Ntxuav lub sensor thiab ntsuas chamber kom tsis txhob tso nyiaj los ntawm kev cuam tshuam kev nyeem ntawv;

Tshawb xyuas cov qauv digital kom nres A / D hloov dua siab tshiab lossis kos npe drift;

Xyuas kom ruaj ntseg lub zog muab thiab grounding kom deb ntawm electromagnetic cuam tshuam.

Kev siv kom zoo ntawm kev mus nrog cov ntsuas ntsuas tau zoo tuaj yeem txhim kho qhov tseeb qhov tseeb thiab kev tsim khoom, ua kom lub neej ntev dua, thiab txo cov nqi tiv thaiv. Hauv kev siv tiag tiag, cov lag luam yuav tsum teeb tsa tag nrho cov kev tswj xyuas voj voog los ntawm kev xaiv, kev teeb tsa, kev ua haujlwm, calibration mus rau kev saib xyuas. Tsuas yog nyob rau hauv txoj kev no tuaj yeem drift meters yooj yim nkag siab txog lawv cov nqi tseem ceeb hauv cov dej muaj peev xwm thiab muab cov ntaub ntawv muaj txiaj ntsig pab rau kev tsim khoom ntse thiab kev tswj hwm kev siv hluav taws xob.
