Ibyiza bya Vortex Flowmeters

Ibipimo by'umuvuduko w'amazi (Vortex flowmeters) ni ibikoresho bipima umuvuduko w'amazi bikora ku ihame rya Karman Vortex Street Effect. Bikoreshwa cyane mu kugenzura ibikorwa by'inganda mu gupima urujya n'uruza rw'imyuka, ibinyobwa bisi n'umwuka, hamwe n'inyungu z'ingenzi zikurikira:

1. Ubuziranenge bwo gupima no guhagarara neza

Ubuziranenge bwo gupima ntibugira ingaruka zikomeye ku mpinduka mu bipimo biri hagati nko gushyuha, ubushyuhe, n'ubucucike. Ubuziranenge bushobora kugera kuri ± 0.5% R ku bintu bivanze, na ± 1% R ku myuka n'umwuka, hamwe n'ikosa ryo gusubiramo riri munsi ya ± 0.2%. Ifite ibikoresho byo gutahura piezoelectric cyangwa capacitive, ifite ubushobozi bukomeye bwo kurwanya ingaruka ku bimenyetso, bigatuma amakuru ahoraho mu gihe kirekire nta gupima kenshi.

2. Ubwoko bwinshi bw'Ibitangazamakuru Bikoreshwa

Ishobora gupima icyarimwe urujya n'uruza rw'amazi, imyuka, n'umwuka, nk'amazi, aside-base solutions, umwuka, gaze karemano, umwuka wuzuye, n'umwuka ushyushye cyane. Kubera ko nta bice bya mekanike bigenda, ntabwo izafungwa cyangwa ngo yambikwe n'imyanda mike (nk'uduce duto n'udupira) mu buryo bw'umwuka, bigatuma ikwiriye imikorere igoye.

3. Imiterere yoroshye n'amafaranga make yo kubungabunga

Iyi sensor ikoresha igishushanyo mbonera gihuriweho kandi igashyigikira uburyo bworoshye bwo kuyishyiraho (guhuza flange, guhuza imigozi, nibindi), bigatuma hadakenerwa ubundi buryo bwo guhindura igice cy’imiyoboro igororotse (imwe mu miterere ihuye n’ibice bigufi by’imiyoboro igororotse). Nta bice by’imiyoboro bishobora kwangirika nk’imashini zikora rotor na impellers, kubungabunga buri munsi bisaba gusa kugenzura imikorere yo gufunga hagati ya sensor n’umuyoboro, bigatuma ikiguzi cyo kuyikoresha no kuyitunganya kiba gito cyane ugereranije n’ibipimo byo kwimura ibintu nk’ibipimo by’imiyoboro ya turbine na metero kare y’imiyoboro.

4. Igipimo cy'ihindagurika ry'amazi mu miterere yabyo

Igipimo cyo kugabanuka kw'amazi gishobora kugera kuri 1:10 ~ 1:30, bigatuma hapimwa neza umuvuduko uri hagati w'amazi mu buryo butandukanye kuva ku buke kugeza ku burebure. Ni byiza cyane ku nganda zifite impinduka nyinshi z'amazi, nko gutanga imiti ikoreshwa mu byuma bitanga umwuka, gukwirakwiza umwuka w'amashanyarazi mu ruganda, no kohereza gazi mu mujyi.

5. Ibisohoka mu buryo bw'ikoranabuhanga kugira ngo byoroshye guhuza sisitemu

Ishyigikira ibicuruzwa bisanzwe birimo ibimenyetso bya analog bya 4-20mA, ibimenyetso bya pulse, n'ibimenyetso bya digitale bya RS485 (Modbus-RTU). Ishobora guhuzwa na PLC, sisitemu zo kugenzura DCS cyangwa urubuga rwa internet y'ibintu mu nganda kugira ngo ikore igenzura ry'amazi mu buryo bwa kure, gupima ingano no kugenzura byikora, ihaza ibyifuzo byo kuvugurura ikoranabuhanga mu nganda.

6. Ubushyuhe bwinshi n'umuvuduko mwinshi mu gihe cy'akazi gakomeye

Iyi sensor ishobora gukorwa mu bikoresho birwanya ingese kandi birwanya ubushyuhe bwinshi nka icyuma kidashonga na Hastelloy, bigahuza n'imiterere y'akazi aho ubushyuhe buri hagati ya -200℃ na +550℃ kandi umuvuduko ukagera kuri megapascals icumi. Ikoreshwa cyane mu nganda zikoresha ubushyuhe bwinshi n'umuvuduko mwinshi nka peteroli, ibyuma n'amashanyarazi.
