Chibatiso che flow meter chinoshanda sei?

Chiyero che clamp-on flow meter chinoshanda nekushandisa tekinoroji ye ultrasonic kuyera kumhanya kwemvura inoyerera nemupombi pasina kuda kubata zvakananga nemvura yacho. Heino tsananguro yakadzama yekushanda kwayo:

1. Zvikamu Zvikuru
• Matransducer: Matransducer maviri eultrasonic akasungirirwa kunze kwepombi. Midziyo iyi inoshanda sezvinhu zvinotumira uye zvinogamuchira mafungu eultrasonic.
• Chigadzirwa cheMagetsi: Chinogadzira zviratidzo zvinobva kumatransducers uye chinoverenga mwero wekuyerera kwemagetsi.

2. Nheyo dzeKuyera

Kune misimboti miviri mikuru yekushanda kwe clamp-on flow meter: Transit-Time uye Doppler Effect.

A. Nheyo yeNguva yeKufamba (Yakajairika)
• Mashandiro Azvo:
• Matransducer anotumira ma ultrasound pulses nemupombi nekona, zvese pasi (nekuyerera) uye kumusoro (kupesana nekuyerera).
• Ruzha rwunofamba rwuchidzika pasi rwunofamba nekukurumidza nekuti rwunobatsirwa nekuyerera kwemvura, ukuwo rwizi rwuchikwira rwuchitora nguva yakareba sezvo rwuchipesana nekuyerera kwemvura.
• Musiyano wenguva dzekufambisa (\Delta t) pakati pezviratidzo zvepasi nekumusoro unoenderana nekumhanya kwekufamba kwemhepo.
• Kuverenga Kuyerera:
Chiyero cheflow meter chinoverenga flow velocity chichishandisa equation: Kana flow speed yangoonekwa, volumetric flow rate inoverengwa zvichibva panzvimbo yecross-sectional yepombi.

B. Nheyo yeDoppler Effect
• Mashandiro Azvo:
• Mafungu e ultrasonic anotumirwa mupombi uye anoburitsa zvidimbu kana mabhurumu ari mumvura.
• Mafungu anoonekwa anosangana nekuchinja kwema frequency (Doppler shift) nekuda kwekufamba kwezvikamu izvi nemvura.
• Kuchinja kwehuwandu hwemafungu kunoenderana nekumhanya kwemvura.
• Nyaya dzekushandisa:
Nzira iyi yakanakira mvura ine zvinhu zvakasimba zvakasungirirwa kana magasi anoputika, zvakaita semvura yakasviba kana slurry.

3. Matanho Ekushanda
1. MaClamp Transducers ari paPaipi: MaCluster anosungirirwa pamusoro pepombi nekona chaiyo, zvichibva pane zvinhu zvepombi, dhayamita, uye rudzi rwemvura.
2. Kuenzanisa: Chiyero ichi chakaenzaniswa nehukuru hwakaita sedhayamita yepombi, ukobvu hwemadziro, uye hunhu hwemvura (semuenzaniso, kuwanda uye kusimba).
3. Kutumira Zviratidzo: Matransducer anotumira uye anogamuchira mafungu e ultrasonic, uye magetsi emuchina wemita anoongorora zviratidzo.
4. Kuverenga Mwero Wekuyerera: Mudziyo uyu unoverenga kumhanya kwemvura woishandura kuita mwero wekuyerera kwemvura, unowanzoonekwa pamudziyo kana kuendeswa kune system yekutarisa.

Mabhenefiti eKugadzira Clamp-On
• Hazvipindi mvura: Hapana chikonzero chekucheka pombi kana kukanganisa kuyerera kwayo.
• Kuchinjika: Inogona kushandiswa pamhando dzakasiyana dzezvinhu zvepombi (semuenzaniso, simbi, PVC) uye saizi.
• Kutakurwa: Kazhinji kunotakurika kana kuchiongororwa zvakananga kana kuyerwa kwenguva pfupi.
• Kuchengetedza Kushoma: Hapana zvikamu zvinofamba kana kusangana nemvura.

Maitiro Akajairika
• Kugoverwa kwemvura uye kugadziriswa kwayo.
• Kutarisa mashandiro emaindasitiri.
• Masisitimu eHVAC.
• Kuongororwa kwesimba remagetsi.
• Mapaipi emafuta negesi.

Kushandiswa kwakasiyana-siyana uku kunoita kuti mita yekuyerera inosungirirwa pamadziro ive sarudzo yakakurumbira mumaindasitiri ese kuti ikwanise kuyera kuyerera kwayo nemazvo, isingakanganisi.
