1. Chiyambi Chachidule
Choyezera kayendedwe ka ukadaulo wa ultrasonic chimapangidwa ndi chowerengera ndi choyezera cha ultrasound. Masensa a ultrasound ophatikizidwa amaphatikizapo choyezera chosalowerera, choyezera cholowetsa ndi choyezera chomwe chimalumikizidwa ku khoma lamkati la pipe kapena pansi pa njira.
Ma transducer a ultrasonic otsekeredwa pa nthawi yoyendera ayenera kuyikidwa pakhoma lakunja la chitoliro choyezedwa pogwiritsa ntchito njira za V, njira za Z ndi njira za W. Chitoliro cha ultrasound cha njira ziwiri chikufanana ndi cha njira imodzi. Kusiyana kwa mita imodzi ya ultrasound yomwe imayendera imafunika sensa imodzi kuti iyikidwe, koma mita iwiri ya ultrasound yomwe imayendera imafunika masensa awiri kuti iyikidwe. Masensa amamangiriridwa kunja ndipo amapeza kuwerenga kwa mayendedwe mwachindunji kudzera pakhoma la chitoliro. Kulondola ndi 0.5% ndi 1%. Chitoliro cha ultrasound cha mtundu wa nthawi yoyendera ndi chabwino poyesa zakumwa zoyera komanso zonyansa pang'ono.
Chomangira cha doppler chopangidwa ndi ma ultrasound transducer chiyenera kuyikidwa pa chitoliro chakunja moyang'anizana ndipo ndibwino kuyesa zakumwa zodetsedwa, payenera kukhala tinthu tating'onoting'ono tomwe tingayambitse kuwunikira kwakutali, tinthu tating'onoting'ono tiyenera kukhala ndi mainchesi osachepera 100 (0.004 in.) m'mimba mwake wa 40mm-4000mm. Ngati madziwo ndi omveka bwino, choyezera kuyenda kwa madzi chamtunduwu sichingagwire ntchito bwino.
Sensa yothamanga m'dera nthawi zambiri imalumikizidwa ku khoma lamkati mwa chitoliro kapena kuyikidwa pansi pa njira. Pa sensa yothamanga m'dera lathu, mulingo wochepa kwambiri wamadzimadzi umafunika kukhala wokwera kuposa 20mm kapena kupitirira kutalika kwa sensa, kutalika kwa sensa ndi 22mm, kuti zitsimikizire kulondola bwino, mulingo wocheperako wamadzimadzi uyenera kukhala kuyambira 40mm mpaka 50mm.
Kuti zitsimikizire kulondola bwino, mitundu yonse iwiri ya mita imafunika chitoliro chokwanira cholunjika, nthawi zambiri, chimafunsa osachepera 10D yakumtunda ndi 5D yakumunsi, komwe D ndi mainchesi a chitoliro. Zigongono, ma valve, ndi zida zina zomwe zimasokoneza kuyenda kwa laminar zimatha kuchepetsa kulondola kwambiri.
2. Momwe mungagwiritsire ntchito mita yoyezera kuyenda kwa ultrasound nthawi yoyendera
Kuti pakhale nthawi yodzaza ya payipi yodutsa, ultrasound flowmeter imatumiza zizindikiro kwa wina ndi mnzake, ndipo kuyenda kwa madzi mu payipi kumayambitsa kusiyana koyezeka mu nthawi yodutsa mawu pamene ikuyenda ndi motsutsana ndi kuyenda. Kutengera ndi kukula kwa payipi, chizindikirocho chingapite mwachindunji pakati pa ma transducer, kapena chingadumphe kuchokera kukhoma kupita kukhoma. Monga ukadaulo wa Doppler, transducer imayesa liwiro la mtsinje, lomwe limamasulira kuti kuyenda.
Chida choyezera kuthamanga kwa dera, Kuthamanga kwa Madzi pafupi ndi DOF6000 Transducer chimayesedwa ndi mawu polemba kusintha kwa Doppler kuchokera ku tinthu tating'onoting'ono ndi thovu la mpweya lopangidwa m'madzi. Kuzama kwa Madzi pamwamba pa DOF6000 Transducer kumayesedwa ndi mphamvu ya Transducer yolemba kuthamanga kwa madzi pamwamba pa chida. Kutentha kumayesedwa kuti kusinthe zojambulira za mawu. Izi zikugwirizana ndi liwiro la mawu m'madzi, lomwe limakhudzidwa kwambiri ndi kutentha. Kuthamanga kwa madzi ndi kuchuluka kwa madzi zimawerengedwa ndi chowerengera cha madzi kuchokera kuzidziwitso zomwe zafotokozedwa ndi ogwiritsa ntchito.
3. Mitundu ya mita yoyezera kuyenda kwa ma ultrasound
Ukadaulo wa nthawi yoyendera: TF1100-EC yokhazikika pakhoma kapena yokhazikika, mtundu wolowetsa wa TF1100-EI, mtundu wa m'manja wa TF1100-CH ndi mtundu wonyamulika wa TF1100-EP;
SC7/ WM9100/Ultrawater inline type ultrasonic flow meter kuphatikiza kulumikizana kwa ulusi ndi kulumikizana kwa flange.
Chomangira chomangirira cha TF1100-DC chomangiriridwa pakhoma pa njira ziwiri zoyezera kuyenda kwa magetsi, choyezera kuyenda kwa magetsi cha TF1100-DI cholowetsa njira ziwiri zoyezera kuyenda kwa magetsi ndi batire yamtundu wa TF1100-DP yonyamula yomwe imagwiritsa ntchito njira ziwiri zoyezera kuyenda kwa magetsi.
Ukadaulo wa nthawi ya Doppler: Wokwera pakhoma wa DF6100-EC kapena wokhazikika, mtundu wa DF6100-EI insertion ndi mtundu wa DF6100-EP wonyamulika.
Njira yothamanga kwa dera: Mtundu wa DOF6000-W wokhazikika kapena wosasinthasintha ndi mtundu wonyamulika wa DOF6000-P;
4. Makhalidwe ofanana
1. Ukadaulo wa akupanga
2. Kawirikawiri, mita yoyezera nthawi yoyendera ya ultrasound imakhala yolondola kwambiri kuposa mita yoyezera nthawi yoyendera ya mtundu wa doppler.
3. Sizingatheke kuyeza madzi opitirira 200℃.
5. Zoletsa zofala
1. Pa nthawi yoyendera ndi doppler full pipe ultrasound flow meter, chitolirocho chiyenera kudzaza ndi madzi opanda thovu la mpweya.
2. Pa zomangira zoyezera kuyenda kwa madzi pogwiritsa ntchito ma ultrasound, mapaipi ayenera kukhala ofanana omwe amatha kutumiza mawu. Zipangizo monga konkriti, FRP, mapaipi achitsulo okhala ndi pulasitiki, ndi zinthu zina zophatikizika zimasokoneza kufalikira kwa mafunde a mawu.
3. Pa mita yoyezera kayendedwe ka madzi yosakhudzana ndi ma ultrasound, chitoliro nthawi zambiri sichiyenera kukhala ndi malo osungira mkati ndipo pamwamba pake payenera kukhala poyera pomwe chosinthira mawu chimayikidwa. Kutumiza mawu kungathandizidwe poika mafuta kapena zinthu zina zofanana pa khoma la chitoliro.
4. Kuti mugwiritse ntchito choyezera madzi chomwe sichilowa m'malo mwa ultrasound, ndi bwino kuyika ma transducer m'mbali mwa chitoliro nthawi ya 3 koloko m'mawa ndi 9 koloko m'mawa, osati pamwamba ndi pansi. Izi zimathandiza kupewa dothi lililonse pansi pa chitoliro.
