Gulu la akupanga flowmeters

Pali mitundu yambiri ya akupanga flowmeters.Malinga ndi magulu osiyanasiyana njira, zikhoza kugawidwa mu mitundu yosiyanasiyana ya akupanga flowmeters.

(1) Mfundo yoyezera ntchito

Pali mitundu yambiri ya ultrasound flowmeter kwa chatsekedwa mapaipi malinga ndi muyeso mfundo, ndipo ntchito kwambiri ndi magulu awiri a zoyendera nthawi ndi Doppler akupanga mfundo.The transit-time ultrasonic flowmeter imagwiritsa ntchito mfundo yakuti nthawi yodutsa pakati pa phokoso la phokoso lomwe likufalikira mumtsinje ndi kufalikira kwamakono mumadzimadzi kumayenderana ndi kuthamanga kwa madzi kuti muyese kuthamanga kwa madzi, omwe ndi amagwiritsidwa ntchito kwambiri poyezera madzi aiwisi m'mitsinje, mitsinje ndi malo osungiramo madzi, kuzindikira kwa kayendedwe kazinthu za petrochemical, komanso kuyeza kwa madzi omwe amamwa popanga.Malinga ndi zothandiza ntchito zosowa, popita nthawi akupanga flowmeter lagawidwa kunyamula nthawi kusiyana akupanga flowmeter, chokhazikika popita nthawi akupanga flowmeter, zodutsa nthawi mpweya akupanga flowmeter.

(2) Amasankhidwa molingana ndi sing'anga yoyezera

Gasi otaya mita ndi madzi otaya mita

(3) Njira ya nthawi yofalitsa imagawidwa molingana ndi chiwerengero cha njira

Malinga ndi kuchuluka kwa mayendedwe omwe amagwiritsidwa ntchito kwambiri monga mono, njira iwiri, njira zinayi ndi eyiti.

Kukonzekera kwa mayendedwe anayi ndi pamwamba pa ma tchanelo ambiri kumakhala ndi zotsatira zabwino pakuwongolera kuyeza kwake.

(4) Yosankhidwa ndi njira yoyika transducer

Ikhoza kugawidwa mumtundu wonyamula, wogwirizira m'manja ndi mtundu wokhazikika.

(5) Gulu molingana ndi mtundu wa transducers

Akupanga flowmeter lagawidwa mitundu itatu: achepetsa pa mtundu, amaika mtundu ndi flange & ulusi mtundu.

Clamp-pa akupanga flowmeter ndi oyambirira kupanga, wosuta kwambiri bwino ndi kugwiritsa ntchito akupanga flowmeter, unsembe wa transducer popanda payipi yopuma, ndiko kuti, izo mokwanira zimasonyeza akupanga flowmeter unsembe ndi yosavuta, yosavuta kugwiritsa ntchito makhalidwe.

Ena mapaipi chifukwa cha zinthu woonda, osauka phokoso conduction, kapena dzimbiri kwambiri, akalowa ndi mapaipi danga kusiyana ndi zifukwa zina, chifukwa chachikulu attenuation akupanga chizindikiro, ndi kunja akupanga flowmeter sangathe anayeza bwinobwino, kotero m'badwo wa chitoliro gawo akupanga flowmeter.The chubu gawo akupanga flowmeter integrates transducer ndi kuyeza chubu, kuthetsa vuto mu kuyeza kunja flowmeter, ndi muyeso kulondola ndi apamwamba kuposa ena akupanga flowmeters, koma nthawi yomweyo, komanso nsembe mwayi wa kunja Ufumuyo akupanga flowmeter osati kuswa otaya unsembe, amafuna unsembe wa transducer mwa odulidwa chitoliro.

The kuyika akupanga flowmeter ndi pakati pa pamwamba awiri.The otaya sangakhoze kusokonezedwa pa unsembe, ntchito zida zapadera nkhonya mabowo mu payipi ndi madzi, ndi amaika transducer mu payipi kumaliza unsembe.Chifukwa transducer ali mu payipi, kufala ndi kulandira chizindikiro chake amangodutsa sing'anga kuyeza, koma osati kudzera chubu khoma ndi akalowa, kotero muyeso wake si malire ndi chubu khalidwe ndi chubu akalowa zakuthupi.
