Ntxuav thiab tiv thaiv kev thaiv
Mechanical flowmeters (xws li turbine lossis iav flowmeters) raug cuam tshuam los ntawm impurities, sediment, lossis nplai buildup nyob rau hauv nruab nrab; Yog li ntawd, cov kua dej thiab cov khoom siv kho tshuab yuav tsum tau ntxuav txhua lub sijhawm. Txawm hais tias electromagnetic thiab ultrasonic flowmeters tsis muaj kev sib txhuam, lawv tseem yuav tsum tau tshawb xyuas lawv cov electrodes thiab cov phab ntsa sab hauv ntawm cov kav dej thaum cov kua muaj cov kua qaub ntau ntawm cov khib nyiab lossis thaum muaj cov khib nyiab. Kev tuav cov dej ntws tsis muaj kev cuam tshuam hauv qhov ntsuas yuav pab ua kom lub sijhawm ntev - ruaj khov ntawm kev ntsuas qhov tseeb.
Kev tshuaj xyuas ib ntus
Tshawb xyuas lub flowmeter lub vaj tse, thaiv cov terminals, tiv thaiv npog, thiab cov ntsaws ruaj ruaj kom ntseeg tau tias tsis muaj cov cim ntawm xoob, tawg, lossis xeb. Kev sib txuas hluav taws xob yuav tsum muaj kev ruaj ntseg los tiv thaiv cov teeb meem tsis sib xws los ntawm kev ya raws los yog kev sib cuag tsis zoo. Rau cov khoom detachable, xyuas kom meej tias lawv tau ruaj khov los tiv thaiv kev txav los yog ntsuas qhov yuam kev los ntawm kev co lossis cuam tshuam ntawm cov kua dej.
Calibration thiab Commissioning
Flowmeters yuav tsum raug ntsuas raws li cov chaw tsim khoom cov lus qhia lossis tsim cov sijhawm pov thawj, tshwj xeeb hauv cov ntawv thov uas suav nrog kev them nqi lag luam lossis siab - kev tswj cov txheej txheem raug. Calibration tuaj yeem ua tau siv cov qauv ntws rigs lossis ntawm - qhov chaw sib piv txoj hauv kev; Thaum lub sijhawm txheej txheem no, qhov xoom taw tes, tag nrho - cov zis tawm, thiab cov ntsiab lus nruab nrab yuav tsum tau kuaj xyuas thiab hloov kho raws li qhov tsim nyog los xyuas kom meej tias qhov ntsuas qhov tseeb ua tau raws li qhov xav tau tshwj xeeb.
Kev tiv thaiv ib puag ncig thiab khaws cov ntaub ntawv
Flowmeters yuav tsum tsis txhob raug rau ncua sij hawm mus rau ib puag ncig uas muaj corrosion hnyav, kub kub, los yog muaj zog electromagnetic cuam tshuam. Thaum tsim nyog, kev tiv thaiv npog lossis tiv thaiv kev ntsuas yuav tsum tau teeb tsa. Tsis tas li ntawd, yuav tsum tau tsim kom muaj ib daim ntawv teev kev saib xyuas los sau cov ntsiab lus hais txog kev tu, calibration, thiab tej yam tsis raug; cov ntaub ntawv no pab txhawb kev txiav txim siab txog kev saib xyuas yav tom ntej- ua thiab tswj cov cuab yeej siv tag nrho.
