Kwamita yoyendera ya ultrasound yomwe imayikidwa nthawi yolumikizirana, mphamvu ya chizindikiro ndi chimodzi mwa zinthu zothandiza kwambiri pozindikira matenda. Komabe, pali kusamvetsetsana kofala:

Mphamvu yayikulu ya chizindikiro sikutanthauza kulondola kwambiri kwa muyeso, ndipo mphamvu yochepa ya chizindikiro sikutanthauza kuti choyezera kuyenda kwa madzi ndi cholakwika.

Mphamvu ya chizindikiro imatiuza makamaka momwe chizindikiro cha ultrasound chimayendera bwino kudzera mu chitoliro ndi madzi komanso momwe chimalandirira bwino ndi transducer yosiyana.

1. Kodi Mphamvu ya Chizindikiro N'chiyani?

Mwachidule,mphamvu ya chizindikiro imasonyeza mphamvu ya chizindikiro cha ultrasound chomwe chimalandiridwa ndi mita yoyendera.

Pa mita yoyezera kuyenda kwa ma ultrasound yolumikizidwa ndi clamp-on, njira ya acoustic ndi pafupifupi:

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

Chotumiziracho chimapanga chizindikiro cha ultrasound, chomwe chimadutsa pakhoma la chitoliro ndi madzi asanafike pa chotumiziracho.

Ngati mphamvu ya mawu imatumizidwa popanda kutayika kwambiri, chizindikiro cholandiridwacho chidzakhala champhamvu. Ngati chizindikirocho chikhala ndi kuchepa kwakukulu, kuwunikira, kapena kufalikira, chizindikiro cholandiridwacho chidzakhala chofooka.

2. Ndi Zinthu Ziti Zomwe Zimakhudza Mphamvu ya Chizindikiro?

Zinthu zingapo zingakhudze kwambiri chizindikiro cha ultrasound chomwe chalandiridwa.

2.1 Chitoliro Chopangira

Zipangizo zosiyanasiyana za mapaipi zimakhala ndi mphamvu zosiyana za mawu.

Zitsanzo zodziwika bwino ndi izi:

• Chitsulo cha kaboni
• Chitsulo chosapanga dzimbiri
• Chitsulo choponyedwa
• PVC
• HDPE
• Chitoliro chopangidwa ndi simenti

Mphamvu ya ultrasound imachita zinthu mosiyana ikadutsa m'zinthu zosiyanasiyana. Chifukwa chake, mita yoyendera madzi yomweyi imatha kuwonetsa mphamvu zosiyanasiyana za chizindikiro ikayikidwa pa mitundu yosiyanasiyana ya mapaipi.

2.2 Kukhuthala kwa Khoma la Chitoliro

Kukhuthala kwa khoma la mapaipi ndikofunikira kwambiri poyesa kayendedwe ka madzi pogwiritsa ntchito ultrasound.

Kawirikawiri, khoma la chitoliro likakula kwambiri, ndiye kuti zinthu zomwe chizindikiro cha ultrasound chiyenera kudutsamo zimakhala zambiri, zomwe zingapangitse kuti mawu achepetseke.

Izi zitha kukhala zofunika kwambiri kwa:

Mapaipi akuluakulu, okhala ndi khoma lokhuthala

Chifukwa chake, kukula kwa chitoliro chokha sikukwanira posankha mita yoyezera kuchuluka kwa madzi yomwe imagwiritsidwa ntchito ndi ma ultrasound.

Mwachitsanzo, m'malo mongopereka:

Kukula kwa chitoliro: DN500

Ndikothandiza kwambiri kupereka:

Chitoliro + Kunja kwa mainchesi + Kukhuthala kwa khoma + Chitoliro cha m'mbali

2.3 Chitoliro cha mapaipi

Kuyika mapaipi kumatha kukhala ndi zotsatirapo zazikulu pa mphamvu ya chizindikiro.

Zipangizo zodziwika bwino zomangira mkati ndi izi:

• PTFE
• Rabala
• Simenti
• Epoxy
• Pulasitiki

Chizindikiro cha ultrasound chingafunike kudutsa:

Chosinthira → Khoma la Paipi → Mkati mwake → Madzi

Ngati mphamvu ya mawu ya mkati mwake ikusiyana kwambiri ndi ya chitoliro ndi madzi, kutayika kwina kwa mawu kungachitike.

Choncho, kudziwa kuti chitoliro ndi "chitsulo" sikokwanira nthawi zonse. Mtundu ndi makulidwe a mkati mwake ziyeneranso kuganiziridwa.

3. N’chifukwa Chiyani Mabomba a Mphepo Amachepetsa Mphamvu ya Chizindikiro?

Ma thovu a mpweya ndi chimodzi mwa zifukwa zomwe zimayambitsa zizindikiro zofooka kapena zosakhazikika za ultrasound.

Popeza mpweya ndi madzi zimakhala ndi mphamvu zosiyana kwambiri zoyatsira mawu, thovu zimatha kufalikira ndikuwunikira mafunde a ultrasound.

Popanda thovu lalikulu la mpweya:

Chizindikiro cha Ultrasonic → Madzi → Chosinthira cholandirira

Ndi thovu la mpweya:

Chizindikiro cha Ultrasonic → Thovu → Kubalalitsa/Kuwunikira → Kutaya mphamvu → Chizindikiro chofooka cholandiridwa

Chifukwa chake, kuchuluka kwa mpweya m'thupi kungayambitse:

• Mphamvu ya chizindikiro yotsika
• Kuwerenga kwa kayendedwe ka madzi kosakhazikika
• Kutayika kwa chizindikiro kwapakati
• Kusakhazikika bwino kwa muyeso

Chifukwa chake, mphamvu ya chizindikiro ikachepa mwadzidzidzi, mainjiniya sayenera kungoyang'ana ma transducer okha komanso kufufuza ngati mpweya uli mu chitolirocho.

4. Kulumikizana kwa Transducer N'kofunikanso

Pa choyezera kuyenda kwa madzi chotchedwa clamp-on ultrasound, transducer sichikhudza mwachindunji madziwo. Chizindikiro cha ultrasound chiyenera kudutsa pakhoma la chitoliro.

Njira yolumikizirana ikhoza kufotokozedwa motere:

Chosinthira → Cholumikizira Cholumikizira → Khoma la Mapaipi

Kulumikizana kolakwika kungachepetse kwambiri mphamvu ya chizindikiro.

Zomwe zimayambitsa matendawa ndi izi:

• Cholumikizira chosakwanira
• Kulumikizana kosafanana
• Dzimbiri kapena dzimbiri pamwamba pa chitoliro
• Utoto wokhuthala kapena wokutira
• Pamwamba pa chitoliro choyipa
• Ma transducer otayirira
• Ma transducer omwe asintha kuchokera pamalo awo oyambirira

Kukonzekera bwino malo ndi kukhudzana bwino kwa makina pakati pa transducer ndi chitoliro ndikofunikira kwambiri kuti ultrasound iperekedwe bwino.

5. Kodi Mphamvu Yaikulu ya Ma Signal Imatanthauza Kulondola Kwambiri?

Osati kwenikweni.

Iyi ndi imodzi mwa mfundo zofunika kwambiri kuzimvetsa.

Mphamvu ya chizindikiro imatiuza makamaka kuti:

"Kodi choyezera kuchuluka kwa madzi m'thupi (flow meter) chingalandire chizindikiro champhamvu chokwanira cha ultrasound?"

Kulondola kwa muyeso, kumbali ina, kumafunsa kuti:

"Kodi kuchuluka kwa madzi omwe ayesedwa ndi kuchuluka kwa madzi omwe akuyenda ndi komwe kuli kofanana bwanji ndi kuchuluka kwa madzi omwe akuyenda?"

Izi ndi zinthu ziwiri zosiyana.

Mwachitsanzo:

Mlandu A

Mphamvu ya Chizindikiro: Yokwera

Koma ma transducer amaikidwa pamalo oipa ndipo mawonekedwe a kayendedwe ka madzi amasokonekera kwambiri.

→ Chizindikiro chingakhale champhamvu, koma muyeso ukhoza kukhala ndi cholakwika.

Mlandu B

Mphamvu ya Chizindikiro: Pakati

Koma ma transducers aikidwa bwino, mikhalidwe ya chitoliro ndi yoyenera, ndipo chizindikirocho ndi chokhazikika.

→ Choyezera kuchuluka kwa madzi chingathebe kuchita bwino poyezera.

Chifukwa chake:

Mphamvu Yaikulu ya Chizindikiro ≠ Kulondola Kwambiri

6. Kodi Kutsika Kwambiri Kumakhala Kotani?

Palibe mphamvu ya chizindikiro cha dziko lonse yomwe ingagwiritsidwe ntchito pa mita iliyonse yoyezera kuyenda kwa ma ultrasound.

Opanga osiyanasiyana amatha kutanthauzira ndikuwonetsa mphamvu ya chizindikiro mosiyana, mwachitsanzo:

• Mphamvu ya Chizindikiro %
• Mphamvu ya Chizindikiro mu dB
• Ubwino wa Chizindikiro
• SNR
• Mulingo wa Chizindikiro Cholandiridwa

Ma parameter awa ndi ofanana, koma ndi ofananasizikutanthauza kuti pali kufanana pakati pa opanga kapena mitundu yosiyanasiyana.

Pa choyezera madzi china chake, buku la malangizo la wopanga ndi tanthauzo la mkati mwa chipangizocho ziyenera kugwiritsidwa ntchito ngati chitsogozo.

7. Mphamvu ya Chizindikiro poyerekeza ndi SNR

Kuti mumvetse bwino, ndikofunikiranso kusiyanitsaMphamvu ya ChizindikirokuchokeraSNR (Chiŵerengero cha Chizindikiro-Ku-Phokoso).

Mphamvu ya Chizindikiromakamaka amafotokoza:

Kodi chizindikiro cha ultrasound chomwe chalandiridwa chili ndi mphamvu yotani?

SNRakufotokoza:

Mphamvu ya chizindikiro chothandizachi poyerekeza ndi phokoso lakumbuyo.

Mwachitsanzo, choyezera kayendedwe ka madzi chingalandire chizindikiro champhamvu, koma ngati phokoso lamagetsi kapena lamakina lili lalikulu, SNR ikhoza kukhalabe yoipa.

Chifukwa chake, pamene chida chikupereka magawo monga:

Mphamvu ya Chizindikiro + SNR + Ubwino wa Chizindikiro

Ndibwino kuti ziwunikidwe pamodzi.

8. Kodi Mphamvu ya Chizindikiro Ingagwiritsidwe Ntchito Bwanji Pothetsa Mavuto?

Njira yothandiza yothetsera mavuto ndikuwona zonse ziwirimulingo ndi kukhazikikaya chizindikiro.
