Kugawa kwa ma flowmeter a ultrasonic

Pali mitundu yambiri ya ma ultrasound flowmeters. Malinga ndi njira zosiyanasiyana zogawa, imatha kugawidwa m'mitundu yosiyanasiyana ya ma ultrasound flowmeters.

(1) Mfundo yoyezera ntchito

Pali mitundu yambiri ya ultrasound flowmeter ya mapaipi otsekedwa malinga ndi mfundo yoyezera, ndipo yomwe imagwiritsidwa ntchito kwambiri ndi magulu awiri a nthawi yoyendera ndi mfundo ya Doppler ultrasonic. Transit-time ultrasonic flowmeter imagwiritsa ntchito mfundo yakuti nthawi yoyendera pakati pa mafunde a phokoso omwe amafalikira mu kuyenda ndi counter-current current mu madzi imagwirizana ndi kuchuluka kwa madzi kuti iyeze kuchuluka kwa madzi, komwe kumagwiritsidwa ntchito kwambiri poyesa madzi osaphika m'mitsinje, mitsinje ndi malo osungiramo madzi, kuzindikira kayendedwe ka zinthu za petrochemical, ndi kuyeza momwe madzi amagwiritsidwira ntchito popanga. Malinga ndi zosowa zogwiritsidwa ntchito, transit time flowmeter ya ultrasonic flowmeter imagawidwa m'magulu awiri: transportable time flowmeter ultrasonic flowmeter, fixed transit time flowmeter ultrasonic flowmeter, transit time gas ultrasonic flowmeter.

(2) Yogawidwa m'magulu malinga ndi sing'anga yoyezedwa

Choyezera kuyenda kwa mpweya ndi choyezera kuyenda kwa madzi

(3) Njira yofalitsira nthawi imagawidwa malinga ndi kuchuluka kwa njira

Malinga ndi chiwerengero cha njira zomwe zimagwiritsidwa ntchito kwambiri, mono, double channel, four-channel ndi eight-channel zimagwiritsidwa ntchito.

Kapangidwe ka njira zinayi ndi zopitilira muyeso zambiri kamakhala ndi zotsatira zabwino pakukweza kulondola kwa muyeso.

(4) Yosankhidwa ndi njira yokhazikitsira transducer

Ikhoza kugawidwa m'magulu awiri: mtundu wonyamulika, mtundu wonyamulika ndi wokhazikika.

(5) Kugawa malinga ndi mtundu wa ma transducer

Choyezera madzi oyeretsera madzi chimagawidwa m'mitundu itatu: chomangira mtundu, mtundu woyika ndi mtundu wa flange ndi ulusi.

Chipangizo choyezera kuyenda kwa ultrasonic cholumikizidwa ndi clamp-on ndiye chopangidwa koyambirira, wogwiritsa ntchito amadziwa bwino kugwiritsa ntchito ultrasound flowmeter, kuyika transducer popanda kusweka kwa payipi, ndiko kuti, chikuwonetsa bwino momwe kukhazikitsa ultrasound flowmeter kulili kosavuta komanso kosavuta kugwiritsa ntchito.

Mapaipi ena chifukwa cha zinthu zoonda, kutulutsa mawu koyipa, kapena dzimbiri lalikulu, kusiyana kwa malo amkati ndi mapaipi ndi zifukwa zina, zomwe zimapangitsa kuti chizindikiro cha ultrasound chichepe kwambiri, ndi ultrasound flowmeter yakunja sikungathe kuyezedwa mwachizolowezi, kotero kupanga ultrasound segment payipi flowmeter. Ultrasonic segment tube flowmeter imagwirizanitsa transducer ndi chubu choyezera, kuthetsa vuto la kuyeza flowmeter yakunja, ndipo kulondola kwa muyeso ndi kwakukulu kuposa kwa ultrasonic flowmeters zina, koma nthawi yomweyo, imatayanso mwayi wa ultrasound flowmeter yolumikizidwa kunja kuti isaswe kukhazikitsa kwa flowmeter, zomwe zimafuna kuyika transducer kudzera mu chitoliro chodulidwa.

Choyezera madzi cholowetsera madzi chili pakati pa ziwiri zomwe zili pamwambapa. Kuyenda kwa madzi sikungasokonezedwe pa kukhazikitsa, kugwiritsa ntchito zida zapadera kuboola mabowo mu payipi ndi madzi, ndikuyika choyezera madzi mu payipi kuti amalize kukhazikitsa. Chifukwa choyezera madzi chili mu payipi, kutumiza ndi kulandira chizindikiro chake kumadutsa kokha kudzera mu sing'anga yoyezedwa, koma osati kudzera pakhoma la chubu ndi padenga, kotero muyeso wake suli wochepa ndi khalidwe la chubu ndi zinthu zoyezera chubu.
