Qhov tseeb installation ntawm lubelectromagnetic flowmeteryog ib qho tseem ceeb heev rau kev ua haujlwm ib txwm muajelectromagnetic flowmeter, ntawm no yog mas lub installation ntawm lubelectromagnetic flowmeter sensorthiablub installation ntawm lub converter.
Yuav tsum tau rau lub installation txoj hauj lwm ntawm lubelectromagnetic flowmeter sensor
Lub sensor ntawmelectromagnetic flowmeteryuav tsum xyuam xim rau cov teeb meem hauv qab no:
①Qhov chaw installation
Kev tiv thaiv qib ntawm lub plhaub ntawm qhov dog digelectromagnetic flow sensoryog IP65 (plua plav thiab dej tsuag qib tau teev tseg los ntawm GB4208), thiab qhov yuav tsum tau ua rau qhov chaw teeb tsa yog:
ib. Thaum ntsuas cov kua theem sib xyaw, xaiv qhov chaw uas yuav tsis ua rau theem sib cais; b. Xaiv qhov chaw uas tsis zoo siab yuav tsis tshwm sim hauv lub raj ntsuas;
c. Zam kev txhim kho nyob ib puag ncig ntawm kev pov hwm hluav taws xob muaj zog xws li motors, transformers, thiab lwm yam, kom tsis txhob muaj kev cuam tshuam ntawm electromagnetic teb; d. Tsis txhob nruab rau hauv qhov chaw uas muaj cov roj corrosive muaj zog nyob ib puag ncig;
e. Qhov ntsuas kub nyob ib puag ncig feem ntau yuav tsum nyob hauv thaj tsam ntawm -25 ~ 60℃, zam lub hnub ncaj qha kom ntau li ntau tau;
f. Nruab rau hauv ib qho chaw uas tsis muaj kev vibration lossis kev vibration qis. Yog tias qhov kev vibration loj dhau lawm, kev txhawb nqa ruaj khov yuav tsum tau ntxiv rau cov kav dej ua ntej thiab tom qab lub sensor;
g. Cov av noo ntawm ib puag ncig feem ntau yuav tsum nyob rau hauv thaj tsam ntawm 10% mus rau 90%;
h. Baidu yuav tsum tsis txhob muab tso rau hauv qhov chaw uas nws tuaj yeem raug los nag lossis dej.
Yog tias qib kev tiv thaiv ntawm lub ntsuas hluav taws xob yog IP67 (qib plua plav pov thawj thiab dej pov thawj) lossis IP68 (qib plua plav thiab submersible), ob yam khoom kawg tuaj yeem raug tshem tawm.
②Ntev ntawm cov yeeb nkab ncaj
Covelectromagnetic flowmetermuaj qhov yuav tsum tau tsawg rau qhov ntev ntawm cov yeeb nkab ncaj nraim nyob rau hauv pem hauv ntej ntawm lub 'meter'. Feem ntau, rau 90 ° luj tshib, T-shaped tees, sib txawv cov yeeb nkab diameters, tag nrho qhib li qub thiab lwm yam kev khiav hauj lwm qhov chaw, yuav tsum muaj ib tug ncaj yeeb nkab ntev ntawm 3 ~ 5D ~ 10 los ntawm cov kab nruab nrab ntawm lub sensor electrode axis (tsis yog lub sensor inlet kawg lub ntsej muag). Rau li qub uas muaj qhov sib txawv, yuav tsum muaj cov yeeb nkab ncaj ntev ntawm 10D; yuav tsum muaj cov yeeb nkab ncaj ntev ntawm 2D ~ 5D tom qab lub sensor. Thaum lub valve tsis tuaj yeem qhib tag nrho, yog tias lub valve kaw qhov chaw yog ntsia ntawm 45 ° rau lub sensor electrode bearing, tuaj yeem txo qhov yuam kev ntxiv.
Qhov ntev ntawm cov kav dej ntws thiab cov dej ntws ncaj nraim tau npaj los ntawm ntau yam kev qhia tshwj xeeb thiab cov qauv kuj tsis sib haum. Cov txiaj ntsig tau tshwm sim yog tias cov yeeb nkab ncaj nraim yog nyob rau hauv thaj tsam ntawm 5D txog 10D, thiab cov yeeb nkab nram qab yog nyob rau hauv thaj tsam ntawm 3D txog 5D.
③Installation txoj hauj lwm thiab ntws kev taw qhia
Covelectromagnetic flow sensortuaj yeem ntsia tau horizontally, vertically lossis obliquely.④Nruab lub bypass yeeb nkab
Txhawm rau ua kom yooj yim rau kev tshuaj xyuas thiab kev hloov kho ntawm xoom point thaum cov kua ntws nyob ruaj khov, cov kav dej hla dhau yuav tsum tau teeb tsa ntau li ntau tau rau cov yeeb nkab me me thiab nruab nrab diameters. Thaum ntsuas cov kua dej uas muaj sediment, cov txheej txheem kev teeb tsa uas yooj yim rau kev ntxuav ntawm lub sensor yuav tsum raug txiav txim siab.
⑤Txhawm rau ua kom qhov ntsuas tau raug thiab cov electrode yuav tsis raug corroded los ntawm tam sim no, lub electromagnetic flow sensor yuav tsum tau grounded nyias, thiab lub sensor thiab cov kua dej yuav tsum nyob ntawm kwv yees li tib lub peev xwm. Sib cais electromagnetic flowmeter, nyob rau hauv txoj cai, lub hauv paus yuav tsum nyob rau sab sensor, thiab converter grounding yuav tsum nyob rau tib qhov chaw hauv av. Feem ntau, lub sensor' s built-in siv electrode lossis hlau raj tuaj yeem ua kom muaj peev xwm sib npaug. Yog li ntawd, cov kua dej hauv lub raj tuaj yeem sib cais los ntawm cov khoom siv hluav taws xob thiab cov hlau, thiab cov phaj hauv av ntawm lub sensor tuaj yeem txuas nrog hauv av xaim.
