Isebenza kanjani i-clamp on flow meter?

I-clamp-on flow meter isebenza ngokusebenzisa ubuchwepheshe be-ultrasonic ukukala ijubane loketshezi olugeleza ngepayipi ngaphandle kokudinga ukuthintana ngqo noketshezi. Nansi incazelo eningiliziwe yendlela olusebenza ngayo:

1. Izingxenye Eziyinhloko
• Ama-Transducer: Ama-transducer amabili e-ultrasonic aboshwe ngaphandle kwepayipi. Lawa madivayisi asebenza njengezinto zokudlulisa kanye nezamukeli zamagagasi e-ultrasonic.
• Iyunithi Ye-elekthroniki: Icubungula izimpawu ezivela kuma-transducer bese ibala izinga lokugeleza.

2. Izimiso Zokulinganisa

Kunezimiso ezimbili eziyinhloko zokusebenza kwamamitha okugeleza asebenza nge-clamp-on: i-Transit-Time kanye ne-Doppler Effect.

A. Isimiso Sesikhathi Sokuhamba (Esivame Kakhulu)
• Indlela Esebenza Ngayo:
• Ama-transducer athumela ama-pulse e-ultrasonic ngepayipi nge-engeli, kokubili phansi (ngokugeleza) naphezulu (ngokumelene nokugeleza).
• Igagasi lomsindo elihamba phansi komfula lihamba ngokushesha ngoba lisizwa ukugeleza koketshezi, kanti igagasi elingaphezulu lithatha isikhathi eside njengoba liphikisana nokugeleza.
• Umehluko wezikhathi zokuhamba (\Delta t) phakathi kwezibonakaliso ezingezansi neziphezulu ulingana nesivinini sokugeleza.
• Ukubalwa Kokugeleza:
Imitha yokugeleza ibala ijubane lokugeleza isebenzisa i-equation: Uma ijubane selinqunyiwe, izinga lokugeleza kwevolumu libalwa ngokusekelwe endaweni yepayipi enqamulayo.

B. Isimiso Somphumela We-Doppler
• Indlela Esebenza Ngayo:
• Amagagasi e-Ultrasonic adluliselwa epayipini futhi aveza izinhlayiya noma amabhamuza oketshezini.
• Amagagasi abonakalisiwe abhekana nokushintsha kwemvamisa (i-Doppler shift) ngenxa yokunyakaza kwalezi zinhlayiya noketshezi.
• Ukushintsha kwemvamisa kuhambisana nesivinini sokugeleza.
• Amacala Okusetshenziswa:
Le ndlela ilungele uketshezi oluqukethe izinto eziqinile ezilengayo noma amabhamuza egesi, njengamanzi angcolile noma i-slurry.

3. Izinyathelo Zokusebenza
1. Ama-Clamp Transducers ePhayiphini: Ama-transducers aboshwe phezu kobuso bangaphandle bephayiphi nge-engeli eqondile, ngokusekelwe ezintweni zephayiphi, ububanzi, kanye nohlobo loketshezi.
2. Ukulinganisa: Imitha ilinganiswa ngemininingwane efana nobubanzi bepayipi, ukujiya kodonga, kanye nezakhiwo zoketshezi (isb., ubuningi kanye nokujiya).
3. Ukudluliselwa Kwesignali: Ama-transducer athumela futhi amukele amagagasi e-ultrasonic, kanti ama-electronics emitha ahlaziya amasignali.
4. Ukubalwa Kwezinga Lokugeleza: Idivayisi ibala ijubane loketshezi bese iyiguqula ibe yizinga lokugeleza elinomthamo, elivame ukuboniswa kudivayisi noma lidluliselwe ohlelweni lokuqapha.

Izinzuzo Zomklamo Wokugoqa
• Ayihlaseli: Asikho isidingo sokusika ipayipi noma ukuphazamisa ukugeleza kwamanzi.
• Ukuguquguquka: Kungasetshenziswa ezintweni ezahlukahlukene zamapayipi (isb., insimbi, i-PVC) kanye nosayizi.
• Ukuphatheka kalula: Ngokuvamile kuyaphatheka kalula uma kuhlolwa ngokushesha noma kulinganiswa okwesikhashana.
• Ukunakekelwa Okuncane: Azikho izingxenye ezihambayo noma ukuthintana noketshezi.

Izicelo Ezivamile
• Ukusatshalaliswa kwamanzi kanye nokwelashwa kwawo.
• Ukuqapha inqubo yezimboni.
• Izinhlelo ze-HVAC.
• Ukuhlolwa kwamandla.
• Amapayipi kawoyela negesi.

Lokhu kuguquguquka kwenza amamitha okugeleza axhunywe ku-clamp abe ukukhetha okuthandwayo kuzo zonke izimboni ukuze kulinganiswe ukugeleza okunembile nokungaphazamisi.
