1. Isingeniso
Ama-flowmeter e-Ultrasoniczamukelwa kabanzi ezimbonini ezahlukene ngenxa yemvelo yazo engahlaseli, ukunemba okuphezulu, kanye nekhono lokulinganisa amazinga okugeleza kohlobo olubanzi loketshezi. Kodwa-ke, ukusebenza kwe-ultrasonic flowmeters kungathonywa kakhulu yizakhiwo ze-linings zamapayipi. Lesi sihloko sihlola ukuthi izinto ezahlukene ze-lining zamapayipi zithinta kanjani ukusebenza kanye nokunemba kwe-ultrasonic.ama-flowmeter.
2. Isimiso Sokusebenza Se-Ultrasonic Flowmeters
Ama-flowmeter e-Ultrasoniczisebenza ngesimiso sokulinganisa umehluko wesikhathi phakathi kwezibonakaliso ze-ultrasonic ezihamba phezulu naphansi koketshezi. Ukuhamba - isikhathi ama-flowmeter e-ultrasonic alinganisa isikhathi esithathwa amagagasi e-ultrasonic ukuhamba kuzo zombili izinhlangothi. Ijubane lokugeleza koketshezi libalwa ngokusekelwe kulo mehluko wesikhathi. Ama-flowmeter e-ultrasonic e-Doppler, ngakolunye uhlangothi, athembele kumphumela we-Doppler. Alinganisa ushintsho emvamisa yamagagasi e-ultrasonic abonakala kusuka ezinhlayiyeni noma amabhamuza oketshezini olugelezayo.
3. Umthelela Wezinto Zokufaka Amapayipi
3.1 Izindwangu Zensimbi
Izendlalelo zensimbi, njengensimbi engagqwali noma i-aluminium, zikhanya kakhulu kumaza e-ultrasonic. Lapho izimpawu ze-ultrasonic zihlangana nezendlalelo zensimbi, ingxenye enkulu yamandla amaza iyabonakala emuva. Lokhu kukhanya kungabangela ukuphazamiseka kwezibonakaliso ezidlulisiwe nezamukelwe kuma-flowmeter e-ultrasonic. Isibonelo, ezisetshenziswa ezimbonini lapho amapayipi anezendlalelo zensimbi esetshenziswa ukuthutha uketshezi olubolayo, ukukhanya okunamandla okuvela ku-line kungaholela ekulinganisweni okungafanele kwesikhathi - sokundiza - noma ukushintsha kwe-Doppler. Ngenxa yalokho, izinga lokugeleza elibaliwe lingaphambuka enanini langempela.
3.2 Ama-Lining enjoloba
Ama-lining enjoloba aziwa ngokuguquguquka kwawo kanye nokumelana okuhle nokugqwala. Kodwa-ke, anokunciphisa okukhulu kwe-acoustic. Amagagasi e-Ultrasonic alahlekelwa amandla amaningi njengoba edlula kuma-lining enjoloba. Lokhu kunciphisa kunganciphisa isilinganiso somsindo wesignali ku-ultrasonicama-flowmeterEzinhlelweni ezinezingqimba zerabha ezijiyile, izimpawu ze-ultrasonic ezitholiwe zingase zibe buthaka kakhulu ukukala ngokunembile amapharamitha okugeleza. Isibonelo, ezitshalweni zokwelapha amanzi angcolile lapho amapayipi anezingqimba zerabha evame khona, ukuncishiswa ngokweqile kwamagagasi e-ultrasonic kungaholela emaphutheni okulinganisa, ikakhulukazi lapho kulinganiswa amazinga okugeleza aphansi.
3.3 Ama-Lining epulasitiki
Ama-lining epulasitiki, njenge-polyethylene (PE) kanye ne-polyvinyl chloride (PVC), abonisa izakhiwo ezahlukene ze-acoustic. Amanye amapulasitiki ane-acoustic impedance ephansi kakhulu, engabangela ukugqagqana okukhulu kwamagagasi e-ultrasonic endaweni ephakathi kodonga lwepayipi kanye ne-lining. Lokhu kugqagqana kungaphazamisa indlela yezibonakaliso ze-ultrasonic, okwenza kube nzima nge-i-flowmeterukukala ngokunembile isikhathi sokundiza noma ukushintsha kwe-Doppler. Ngaphezu kwalokho, ama-lining epulasitiki angase amunce inani elithile lamandla e-ultrasonic, okunciphisa kakhulu amandla esignali. Isibonelo, ezinhlelweni zokunisela ezisebenzisa amapayipi afakwe i-PVC, ukujikijelwa kanye nokumuncwa kwamagagasi e-ultrasonic yi-lining kungaholela ekulinganisweni kokugeleza okunganembile.
3.4 Ama-Lining e-Ceramic
Ama-lining e-ceramic avame ukusetshenziswa ezindaweni ezinokushisa okuphezulu nokukhuhlayo ngenxa yokumelana kwawo okuhle kakhulu nokuguguleka kanye nokuqina kokushisa okuphezulu. Kodwa-ke, izinto ze-ceramic zine-acoustic impedance ephezulu, engabangela ukubonakaliswa okunamandla kwamagagasi e-ultrasonic. Njenge-lining yensimbi, ukubonakaliswa okuvela kuma-lining e-ceramic kungaphazamisa ukusebenza okuvamile kwama-flowmeter e-ultrasonic. Ezimbonini ezifana nokumba izimayini kanye nokukhiqizwa kwesimende, lapho amapayipi ane-lining e-ceramic esetshenziswa khona ukuthutha ama-slurry akhuhlayo, ukubonakaliswa okunamandla kwamagagasi e-ultrasonic avela kuma-lining e-ceramic kungabangela ukulinganiswa kokugeleza okungathembekile.
4. Amasu Okunciphisa Ubunzima
Ukuze kuncishiswe umthelela wemigqa yamapayipi kuma-flowmeter e-ultrasonic, kungasetshenziswa amasu amaningana. Enye indlela ukukhetha uhlobo olufanele lwe-flowmeter ye-ultrasonic ngokusekelwe ezicini zemigqa yamapayipi. Isibonelo, kumapayipi anemigqa ekhanyayo kakhulu, ama-flowmeter e-ultrasonic ohlobo lwe-Doppler angase afaneleke kakhulu njengoba engathinteki kakhulu ukubonakaliswa kwesignali. Elinye isu ukwenza ngcono ukufakwa kwe-flowmeter. Lokhu kuhlanganisa ukuqinisekisa ukuhambisana okufanele kwama-transducer e-ultrasonic nokukhetha indawo efanele yokufaka ukuze kuncishiswe umthelela wokuphambuka kwesignali okuhlobene nemigqa. Ngaphezu kwalokho, amasu okucubungula isignali athuthukisiwe angasetshenziswa ukuthuthukisa ukunemba kokulinganisa ukugeleza lapho kukhona imigqa yamapayipi.
5. Isiphetho
Izinto ezisetshenziswa kumapayipi zidlala indima ebalulekile ekusebenzeni kwama-flowmeter e-ultrasonic. Izinto ezisetshenziswa kumapayipi ahlukahlukene, njengensimbi, irabha, ipulasitiki, kanye ne-ceramic, zingaba nemiphumela ehlukahlukene kumasignali e-ultrasonic, okuhlanganisa ukubonakaliswa, ukuncishiswa, kanye nokuguqulwa. Ukuqonda le miphumela nokusebenzisa amasu okunciphisa afanele kubalulekile ukuqinisekisa ukulinganiswa kokugeleza okunembile nokuthembekile ekusetshenzisweni kwezimboni. Ngokucabanga ngokucophelela ngezakhiwo zamapayipi kanye nokukhetha i-flowmeter ye-ultrasonic efanele kanye nendlela yokufaka, izimboni zingathuthukisa ukusebenza kwazo.ukulinganisa ukugelezaizinhlelo.
