Kuyika mapaipi ndi chinthu chofunikira kuganizira mukakhazikitsachoyezera kuyenda kwa ma ultrasoundNgakhale kuti ma transducer amaikidwa kunja kwa chitoliro, chizindikiro cha ultrasound chiyenera kudutsa pakhoma la chitoliro ndipo, nthawi zambiri, mkati mwake musanafike pamadzi.

Chifukwa chake, mtundu ndi makulidwe a chingwe cha chitoliro zimatha kukhala ndi mphamvu yayikulu pamphamvu ya chizindikiro, kutumiza mawu, malo osinthira mawu, ndi kukhazikika kwa muyeso.

1. Kodi Chizindikiro cha Ultrasonic Chimayenda Bwanji Kupyola mu Chitoliro Chokhala ndi Mizere?

Pa mita yoyezera kuyenda kwa ultrasound yokhazikika, chizindikiro cha ultrasound chimatsatira njira yofanana ndi iyi:

Chosinthira → Khoma la Paipi → Mkati mwa Paipi → Madzi → Mkati mwa Paipi → Khoma la Paipi → Chosinthira

Mosiyana ndi choyezera madzi cholowetsera, ma transducer sakhudza mwachindunji madziwo.

Chizindikiro cha ultrasound chiyenera kudutsa muzinthu zosiyanasiyana chisanafike pamadzimadzi. Chinthu chilichonse chili ndi mphamvu zosiyana za mawu, kotero chizindikirocho chikhoza kukhala ndi kuwunikira, kusinthasintha, ndi kuchepa kwa kuwala pakati pa zinthuzo.

Ichi ndichifukwa chake payipi iyenera kuganiziridwa poika mita yoyezera kuyenda kwa madzi pogwiritsa ntchito ultrasound.

2. N’chifukwa Chiyani Zinthu Zomangira Mkati Ndi Zofunika?

Zipangizo zosiyanasiyana zamkati zimakhala ndi zosiyanaimpedance ya mawu ndi liwiro la mawu.

Zipangizo zodziwika bwino zolumikizira mapaipi ndi izi:

• PTFE
• Rabala
• Rabala yolimba
• Simenti ya simenti
• Epoxy
• Pulasitiki
• Zophimba zina zoteteza

Pamene mafunde a ultrasound akuyenda kuchokera ku chinthu chimodzi kupita ku china, gawo la mphamvu zake likhoza kuwonetsedwa pa mawonekedwe ake.

Mwachitsanzo:

Khoma la Chitoliro → Mkati mwake → Madzi

Pa mawonekedwe aliwonse, kusiyana kwa mphamvu ya acoustic kungakhudze kuchuluka kwa mphamvu ya ultrasound yomwe imalowa muzinthu zotsatirazi.

Ngati kusalingana kwa mawu kuli kwakukulu, mphamvu zambiri zitha kuwonetsedwa ndipo mphamvu zochepa zitha kufikira chosinthira cholandirira.

Izi zitha kubweretsa:

Mphamvu yotsika ya chizindikiro ndi muyeso wovuta kwambiri wa mawu.

3. N’chifukwa Chiyani Kukhuthala kwa Mzere wa Mkati Kuli Kofunika?

Kukhuthala kwa m'mbali mwa nsalu n'kofunika kwambiri.

Chipinda chopyapyala chingakhale ndi zotsatira zochepa, pomwe chipinda chokhuthala chingathe kuwonjezera kwambiri kutalika kwa njira yolumikizirana kudzera mu chipindacho.

Pamene chizindikiro cha ultrasound chikuyenda kudzera mu membrane, gawo la mphamvu zake limatha kuchepa.

Chifukwa chake, mkhalidwe woyezera umakhudzidwa ndi:

Zipangizo Zomangira M'kati + Kukhuthala kwa Mkati + Katundu Wokometsera

Pachifukwa ichi, mapaipi awiri okhala ndi mainchesi ofanana ndi zinthu zakunja zomwezo akhoza kuchita mosiyana ngati mipata yawo yamkati ndi yosiyana.

Mwachitsanzo:

Chitoliro chachitsulo cha kaboni chopanda mkati

ndi

Chitoliro chachitsulo cha kaboni chokhala ndi mkati mwa rabara wokhuthala

akhoza kukhala ndi makhalidwe osiyana kwambiri a ultrasound transmission.

4. N’chifukwa Chiyani Mapepala a Rabala ndi Mapulasitiki Angakhale Ovuta?

Zipangizo zina zofewa kapena zothamanga pang'ono zingapangitse kuti kuyeza kwa ultrasound kukhale kovuta.

Zitsanzo zikuphatikizapo zina:

• Zophimba za rabara
• Zingwe za PTFE
• Mapepala apulasitiki

Mafunde a ultrasound amatha kukhala ndi kuchepa kapena kuwunikira kwakukulu akamadutsa muzinthu izi.

Izi zingayambitse:

• Mphamvu ya chizindikiro yotsika
• Kuvuta kowonjezereka pakupeza chizindikiro
• Malo ochepa a malo oyenera a transducer
• Kuzindikira kwambiri momwe zinthu zilili

Izi sizikutanthauza kuti mapaipi okhala ndi mipanda sangathe kuyezedwa.

M'malo mwake, choyezera kuchuluka kwa madzi chiyenera kusankhidwa bwino ndikukonzedwa malinga ndi momwe chitolirocho chilili komanso momwe chimagwirira ntchito.

5. Kodi Chipinda cha Mapaipi Chimakhudza Bwanji Kutalikirana kwa Transducer?

Pa mita yoyezera kuyenda kwa ma ultrasound, malo olumikizira ma transducer nthawi zambiri amawerengedwa kutengera magawo angapo, kuphatikizapo:

• Chitoliro cha m'mimba mwake
• Kukhuthala kwa khoma la chitoliro
• Chitoliro cha zinthu
• Zipangizo zomangira
• Kukhuthala kwa m'mphepete
• Mtundu wamadzimadzi
• Kutentha kwamadzimadzi
• Liwiro la akupanga kudzera mu zipangizo zosiyanasiyana

Chifukwa chake, ngati chidziwitso cha mzere chomwe chalowetsedwa mu flow meter sichili cholondola, mtunda wowerengera wa transducer ukhozanso kukhala wolakwika.

Mwachitsanzo, ngati chitoliro chenicheni chili ndi pulasitiki ya 5 mm koma chidacho chakonzedwa ngati chitoliro chachitsulo chosalumikizidwa, njira yowerengera mawu yomwe yawerengedwa singagwirizane molondola ndi kapangidwe ka chitoliro chenichenicho.

Izi zingapangitse kuti kupeza chizindikiro kukhale kovuta kwambiri ndipo kungakhudze momwe muyeso umagwirira ntchito.

6. Kodi Chida Choyezera Mafunde Chingakhale ndi Chizindikiro Champhamvu pa Chitoliro Chokhala ndi Mzere?

Inde.

Chitoliro chokhala ndi m'mbali sizitanthauza kuti chizindikiro cha ultrasound chidzakhala chofooka.

Mphamvu yeniyeni ya chizindikiro imadalira zotsatira zophatikizana za:

Chitoliro + Kukhuthala kwa Khoma + Mkati + Madzi + Chosinthira + Kukhazikitsa

Kukhazikitsa bwino pa chitoliro cholumikizidwa kungaperekebe chizindikiro chokhazikika komanso champhamvu cha ultrasound.

Chifukwa chake, kupezeka kwa denga sikuyenera kuonedwa ngati chizindikiro chokha chakuti kuyeza kwa ultrasound sikoyenera.

7. Kodi Mabomba a Mphepo Angawonjezere Bwanji Vutoli?

Mapaipi okhala ndi mipanda angayambitsenso vuto lina: kusonkhanitsa mpweya.

Ngati chitolirocho sichinadzazidwe mokwanira, kapena ngati pali thovu la mpweya mumadzimadzi, chizindikiro cha ultrasound chikhoza kuchepa kwambiri kapena kufalikira.

Mkhalidwe wophatikizana wa:

Chipinda chokhuthala + Ma thovu a mpweya + Cholumikizira chofooka

kungapangitse kutumiza kwa chizindikiro cha ultrasound kukhala kovuta kwambiri.

Chifukwa chake, malo oyikamo ayenera kusankhidwa bwino pagawo la chitoliro chodzaza kwathunthu, kutali ndi malo omwe mpweya ungaunjikane.

8. Kodi Mainjiniya Ayenera Kuyesa Bwanji Chitoliro Chokhala ndi Mzere?

Musanayike choyezera kuchuluka kwa madzi m'thupi (ultrasound flow meter), ndi bwino kusonkhanitsa mfundo zotsatirazi:

1. Chitoliro chakunja m'mimba mwake
2. Kukhuthala kwa khoma la chitoliro
3. Chitoliro cha zinthu
4. Zipangizo zomangira
5. Kukhuthala kwa m'mphepete
6. Mtundu wamadzimadzi
7. Kutentha kwamadzimadzi
8. Liwiro la kuyenda lomwe limayembekezeredwa
9. Mkhalidwe wa chitoliro
10. Utali wa chitoliro cholunjika ulipo

Izi zimathandiza kuti choyezera kayendedwe ka mawu chidziwe bwino momwe mawu amamvekera komanso malo olumikizirana ma transducer amagwirira ntchito.

Pa ntchito zovuta, kuyesa komwe kumachitika pamalopo kungakhale kothandiza musanayambe kukhazikitsa komaliza.

9. Kodi Zizindikiro Zachizolowezi za Vuto Lokhudzana ndi Kuphimba M'kati Ndi Ziti?

Vuto la mawu okhudzana ndi lining lingawoneke ngati:

• Mphamvu yochepa ya chizindikiro
• Mphamvu ya chizindikiro chosakhazikika
• Kuvuta kupeza chizindikiro cha ultrasound
• Kuwerenga kwa kayendedwe kolakwika kapena kosakhazikika
• Kutayika kwa chizindikiro pafupipafupi
• Kuzindikira kwambiri malo a transducer

Komabe, zizindikiro zimenezi sizikutanthauza kuti denga lokhalo ndilo limayambitsa vutoli.

Zizindikiro zofanana zimathanso kuchitika chifukwa cha:

• Cholumikizira chopanda mphamvu cha transducer
• Malo olakwika a transducer
• Kukhuthala kwambiri kwa khoma la chitoliro
• Ma thovu a mpweya
• Magawo olakwika a chitoliro
• Kutupa kwa pamwamba pa chitoliro
• Kugwedezeka kwa chitoliro

Chifukwa chake, kuthetsa mavuto kuyenera kuganizira njira yonse ya mawu m'malo mongoyang'ana pa mzere wokha.

Chingwe cha mapaipi chimakhudza kuyeza kwa kayendedwe ka ultrasound chifukwa chizindikiro cha ultrasound chiyenera kudutsakhoma la chitoliro ndi mkati mwake musanalowe mumadzimadzi.

Zipangizo zamkati ndi makulidwe ake zimatha kukhudza kutumiza kwa mawu, kuchepetsa chizindikiro, kuwunikira, komanso mtunda wofunikira wa transducer.

Zinthu zazikulu zitha kufotokozedwa mwachidule motere:

Chitoliro + Kukhuthala kwa Khoma + Chitoliro + Kukhuthala kwa M'mbali + Katundu wa Madzi → Kutumiza kwa Acoustic → Ubwino wa Chizindikiro → Kukhazikika kwa Muyeso

Chifukwa chake, posankha ndikuyika choyezera kuyenda kwa ma ultrasound, chitoliro cha mapaipi chiyenera kuonedwa ngati gawo lofunikira pa njira yoyezera ma acoustic.

Chitoliro cholumikizidwa sichimaletsa kuyeza kwa ultrasound, komaZinthu zomangira ndi makulidwe ake ziyenera kuganiziridwa bwino posankha mita yoyendera madzi, kukonza ma parameter, ndi kukhazikitsa transducer..
