Kuyeza kwa madzi opanda mchere

Pakupanga mphamvu, kuchuluka kwa madzi osagwiritsidwa ntchito m'mafakitale amphamvu ndi kwakukulu, momwe mungayezere bwino madzi osagwiritsidwa ntchito m'mafakitale amphamvu ndi vuto lalikulu kwa ogwiritsa ntchito. Malinga ndi njira yachikhalidwe yosankhira flowmeter, nthawi zambiri ndi kusankha orifice flowmeter, kapena turbine flowmeter. Electromagnetic flowmeter si yoyenera kuyeza brine wosagwiritsidwa ntchito m'mafakitale amphamvu, electromagnetic flowmeter imafuna kuti medium ikhale madzi oyendetsera kuti ikwaniritse zofunikira zoyambira za ntchito yake yanthawi zonse. Ngakhale electromagnetic flowmeter ili ndi kulondola kwakukulu komanso kugwira ntchito kokhazikika, si vuto poyesa zinthu wamba, monga zimbudzi, madzi opangidwa ndi ion, acid, alkali ndi mchere, koma chifukwa madzi osagwiritsidwa ntchito m'mafakitale amphamvu ali ndi ma ion ochepa komanso ma conductivity ochepa, conductivity yake siyingakwaniritse zofunikira zoyezera, kotero electromagnetic flowmeter siyingayeze kuyenda kwa madzi osagwiritsidwa ntchito m'mafakitale amphamvu.

Choyezera madzi oyenda pansi ndi choyezera madzi oyenda pansi ndi za mtundu wachikhalidwe wa choyezera madzi, chifukwa ziwalo zoyezera ziyenera kukhudzana mwachindunji ndi choyezera, palinso zolakwika zosiyanasiyana monga kutsekeka, kulondola kosakwanira, ndi mavuto okhazikitsa. Zotsatira zake sizoyenera. Pakuwunika malo, koma zimakhala ndi zofooka zambiri, chifukwa ndi madzi ochotsedwa mchere a pampu ya centrifugal, nthawi zambiri imamatiridwa ndi zinyalala, ndipo pamakhala pampu yoyambira nthawi zambiri, rotor nthawi zambiri imasweka!

Chifukwa chake, pofuna kuzindikira kutuluka kwa madzi amchere, nthawi zambiri timalimbikitsa makasitomala athu kugwiritsa ntchito chipangizo choyezera madzi amchere cha external clamp-on, chomwe ndi chabwino kwambiri poyesa kutuluka kwa madzi amchere. Zifukwa zomwe zingathandize ndi izi:

1, kusiyana kumeneku ndi pakati pa flowmeter ya ultrasonic ya mtundu wa clamp ndi electromagnetic flowmeter, flowmeter ya ultrasound ya mtundu wa clamp-on sikhudzidwa ndi conductivity ya madzi, ndipo imatha kuyeza molondola flowmeter ya electromagnetic flowmeter singathe kuyeza conductivity yochepa ya madzi oyera kapena madzi ena.

2, kulondola kwa flowmeter ya ultrasound ya mtundu wa clamp-on kumakwaniritsa zofunikira muyeso, ndipo kulondola kwake nthawi zambiri kumakhala ±1%, ndi ±0.5% pambuyo pokonza.

3, choyezera chakunja cha mtundu wa clamp-on ultrasonic chifukwa choyezera chake chili kunja kwa khoma la chubu, kudzera mu cholumikizira kuti chilumikizane kwambiri ndi khoma la chubu, ndipo sichikugwirizana mwachindunji ndi sing'anga yoyezera, palibe choletsa, nthawi yake yogwirira ntchito ikhoza kutsimikizika bwino.

4, mphamvu yolimbana ndi kusokoneza, kukula kwa magetsi ambiri, kukwaniritsa zosowa za malo.

5, kukhazikitsa cholumikizira chakunja pa ultrasound flowmeter ndikosavuta kwambiri, bola ngati cholumikizira chakunja pa sensa chayikidwa pa chitoliro chakunja, kuti tipewe kudula chitoliro ndikuipitsa madzi amchere.

Cholumikizira cha Lanry pa ultrasonic flowmeter ndi chinthu chabwino kwambiri choyezera kuyenda kwa madzi, choyenera kwambiri pa PVC, chitsulo chopangidwa ndi chitsulo chosapanga dzimbiri ndi zida zina zapaipi, sichingoyenera poyezera ma electromagnetic flowmeters ndipo zinthu zina sizingathe kupangitsa kuti madzi azikhala ochepa kuwonjezera pa madzi amchere kapena madzi oyera, komanso choyenera mitundu ina yamadzimadzi. Kulondola kwa ultrasound flowmeter poyezera kuyenda kwa madzi sikukhudzidwa ndi kutentha, kuthamanga, kukhuthala, kuchulukana ndi magawo ena a thupi loyezera kuyenda kwa madzi, zomwe zimathetsa vuto la kuyeza kuyenda kwa madzi amphamvu, osayendetsa magetsi, owononga komanso oyaka moto komanso ophulika omwe ndi ovuta kuwayeza ndi mitundu ina ya mamita.
