Kufotokozera akupanga otaya mita

1. Mawu Oyamba Mwachidule

Akupanga ukadaulo otaya mita imapangidwa ndi chowerengera ndi akupanga sensa.Masensa opangidwa ndi ma ultrasonic paired amaphatikizapo sensa yosasokoneza, sensa yolowetsa ndi sensor yomwe imamangiriridwa ku pipewall yamkati kapena pansi pa tchanelo.

Kuchepetsa pa nthawi yodutsa ma transducers akupanga ayenera kuyikidwa pakhoma lakunja la chitoliro choyezedwa ndi njira za V, njira ya Z ndi njira ya W.Magawo awiri akupanga otaya mita ndi ofanana ndi njira imodzi.Kusiyanitsa komwe mita imodzi yothamanga ya ultrasonic flow mita imafunikira sensa imodzi kuti ikhazikitsidwe, koma ma mayendedwe apawiri akupanga ma ultrasonic flow mita amafunikira ma awiri awiri a masensa kuti ayike.Masensa amatsekeredwa kunja ndipo amawerengedwa molunjika kudzera pakhoma la chitoliro.Kulondola ndi 0.5% ndi 1%.Nthawi yodutsa yamtundu wa ultrasound sensor ndiyabwino kuyeza zamadzimadzi zoyera komanso zakuda pang'ono.

Clamp pa doppler akupanga ma transducers ayenera kuyikidwa pa chitoliro chakunja moyang'anizana ndi mnzake ndipo ndi bwino kuyeza zamadzimadzi zonyansa, payenera kukhala tinthu tating'onoting'ono tomwe timayambitsa kuwunikira kotalika, tinthu tating'onoting'ono tikuyenera kukhala osachepera 100 microns (0.004) mu.) m'mimba mwake 40mm-4000mm, Ngati madzi ndi omveka bwino, mtundu otaya mita sangagwire bwino.

Area velocity sensor nthawi zambiri imamangiriridwa ku khoma lamkati la chitoliro kapena kuyika pansi pa njira.Kwa sensa yathu yama velocity, madzi otsika kwambiri amafunikira kukhala apamwamba kuposa 20mm kapena kuposa kutalika kwa sensor, kutalika kwa sensor ndi 22mm, kuonetsetsa kulondola kwabwino, min.mulingo wamadzimadzi uyenera kukhala kuchokera 40mm mpaka 50mm.

Kuonetsetsa kulondola kwabwino, mitundu yonse ya mita imafunikira chitoliro chokwanira chowongoka, nthawi zambiri, idafunsa kumtunda kwa 10D ndi kumunsi kwa mtsinje 5D, pomwe D ndi m'mimba mwake.Zigongono, ma valve, ndi zida zina zomwe zimasokoneza kutuluka kwa laminar zimatha kuchepetsa kulondola kwambiri.

2. Momwe mungagwirire ntchito yodutsa nthawi akupanga otaya mita

Pakuti zonse wodzazidwa chitoliro podutsa nthawi akupanga flowmeter, iwo kufalitsa zizindikiro kwa wina ndi mzake, ndi kayendedwe madzimadzi mu chitoliro kumapangitsa kusiyana koyezeka mu phokoso podutsa nthawi imayenda ndi ndi otaya.Kutengera kukula kwa chitoliro, chizindikirocho chimatha kupita molunjika pakati pa ma transducers, kapena amatha kudumpha kuchokera kukhoma kupita kukhoma.Monga ukadaulo wa Doppler, transducer imayesa kuthamanga kwa mitsinje, yomwe imatanthawuza kuyenda.

Area liwiro mtundu otaya mita, Kuthamanga kwa madzi pafupi ndi DOF6000 Transducer amayezedwa acoustically ndi kujambula Doppler kusintha kwa particles ndi tinthu ting'onoting'ono mpweya thovu ananyamula m'madzi.Kuzama kwamadzi pamwamba pa DOF6000 Transducer kumayesedwa ndi kukakamiza Transducer kujambula kuthamanga kwa madzi pamwamba pa chidacho.Kutentha kumayezedwa kuti muwongolere zojambulidwa zamayimbidwe.Izi zimagwirizana ndi liwiro la phokoso m'madzi, lomwe limakhudzidwa kwambiri ndi kutentha.Mayendedwe ndi kuchuluka kwa mayendedwe ake amawerengedwa ndi chowerengera chochokera kuzomwe zimatanthauzidwa ndi ogwiritsa ntchito.

3. Mitundu ya akupanga otaya mita

Ukadaulo wa nthawi yopita : Khoma la TF1100-EC lokwezedwa kapena kukhazikitsidwa kwamuyaya, mtundu woyika wa TF1100-EI, mtundu wapamanja wa TF1100-CH ndi mtundu wonyamula wa TF1100-EP;

SC7/ WM9100/Ultrawater okhala pakati pamtundu wa akupanga madzi otaya mita kuphatikiza kulumikiza ulusi ndi kulumikizana kwa flange.

TF1100-DC khoma-wokwera achepetsa pa njira ziwiri akupanga flowmeter, TF1100-DI kuyika mtundu awiri njira akupanga otaya mita ndi TF1100-DP kunyamula mtundu batire opareshoni njira ziwiri akupanga otaya mita.

Ukadaulo wa nthawi ya Doppler: Khoma la DF6100-EC lokwera kapena lokhazikika, DF6100-EI mtundu woyika ndi DF6100-EP mtundu wonyamula.

Kuthamanga kwa dera: DOF6000-W mtundu wokhazikika kapena woyima ndi mtundu wa DOF6000-P;

4. Makhalidwe ofanana

1. Akupanga luso

2. Nthawi zambiri, zoyendera nthawi akupanga otaya mita ndi yolondola kuposa doppler mtundu otaya mita .

3. Sangathe kuyeza kuposa 200 ℃ zamadzimadzi.

5. Zolepheretsa wamba

1. Pakuti Transit nthawi ndi doppler zonse chitoliro akupanga otaya mita, chitoliro ayenera kukhala wodzaza madzi popanda mpweya thovu .

2. Kuti achepetse pa akupanga otaya mamita, mapaipi ayenera kukhala homogenous zipangizo angathe kufalitsa phokoso.Zida monga konkriti, FRP, chitoliro chachitsulo chokhala ndi pulasitiki, ndi zinthu zina zimasokoneza kufalikira kwa mafunde.

3. Pakuti sanali kukhudzana akupanga otaya mita, chitoliro zambiri sayenera mkati madipoziti ndi kunja padziko ayenera kukhala woyera kumene transducer mounts.Kutumiza kwa mawu kumatha kuthandizidwa ndikuyika mafuta kapena zinthu zofananira pamawonekedwe ndi khoma la chitoliro.

4. Pakuti sanali olanda akupanga otaya mita, ndi bwino phiri transducers pa mbali ya chitoliro pa 3:00 ndi 9:00 malo, osati pamwamba ndi pansi.Izi zimapewa matope aliwonse pansi pa chitoliro.
