Differential siab flowmeter
Differential siab (tseem hu ua throttling) flowmeter yog ua raws li lub hauv paus ntsiab lus ntawm cov kua dej ntws tawm thiab siv qhov sib txawv ntawm qhov sib txawv thaum cov kua ntws los ntawm cov cuab yeej throttling kom paub txog kev ntsuas ntws. Nws yog ib qho ntawm cov paub tab thiab feem ntau siv txoj hauv kev los ntsuas qhov ntws hauv kev tsim khoom. Nws feem ntau yog tsim los ntawm cov cuab yeej throttling uas tuaj yeem hloov qhov ntsuas ntsuas mus rau qhov sib txawv ntawm qhov sib txawv, qhov ntsuas qhov sib txawv thiab cov ntsuas ntsuas uas tuaj yeem hloov qhov sib txawv ntawm qhov sib txawv rau hauv tus nqi ntws. Hauv cov cuab yeej sib xyaw ua ke, qhov sib txawv siab teeb liab tsim los ntawm cov cuab yeej throttling feem ntau hloov mus rau hauv cov qauv teeb liab (hluav taws xob lossis roj) los ntawm qhov sib txawv siab transmitter rau zaub, kaw lossis tswj.
Differential siab flowmeter yog tsim los ntawm cov cuab yeej tseem ceeb (kwv yees) thiab cov khoom siv thib ob (differential siab converter thiab flow display instrument). Qhov sib txawv siab flowmeter feem ntau yog cais nyob rau hauv daim ntawv ntawm kev tshawb nrhiav qhov chaw, xws li orifice flowmeter, venturi flowmeter, nruab nrab lub raj flowmeter, pitot tube txoj cai pitoba flowmeter, thiab lwm yam.
Cov khoom siv thib ob yog ntau yam khoom siv hluav taws xob, hluav taws xob thiab hluav taws xob sib xyaw ua ke sib txawv siab ntsuas, qhov sib txawv siab transmitters thiab cov twj tso kua mis ntws. Nws tau tsim rau hauv chav kawm loj ntawm cov cuab yeej nrog qib siab ntawm peb Standardization (serialization, generalization thiab standardization) thiab complex hom thiab specifications. Nws tuaj yeem ntsuas tsis tau tsuas yog ntws tsis tau xwb, tab sis kuj tseem muaj lwm yam (xws li siab, qib khoom, ntom, thiab lwm yam).
Raws li nws txoj haujlwm tseem ceeb, qhov kev tshawb nrhiav qhov sib txawv ntawm qhov sib txawv siab flowmeter tuaj yeem muab faib ua throttling ntaus ntawv, hom hydraulic tsis kam, hom centrifugal, dynamic head type, dynamic head gain type thiab jet type.
Cov ntawv xeem tuaj yeem muab faib ua ob pawg raws li lawv cov qib ntawm Standardization: tus qauv thiab tsis yog tus qauv.
Lub npe hu ua standard test piece yog tsim, tsim, ntsia thiab siv raws li cov ntaub ntawv txheem, thiab nws cov nqi ntws yuav txiav txim tau thiab qhov kev ntsuas qhov yuam kev yuav raug kwv yees yam tsis muaj calibration tiag tiag.
Cov ntawv xeem uas tsis yog qauv yog cov uas tsis muaj kev loj hlob thiab tsis tau teev nyob rau hauv cov qauv thoob ntiaj teb.
