Ukufakwa kwamapayipi kuyisici esibalulekile okufanele usicabangele lapho ufaka i-imitha yokugeleza kwe-ultrasonic ebanjiweNakuba ama-transducer efakwe ngaphandle kwepayipi, isignali ye-ultrasonic kumele idlule odongeni lwepayipi futhi, ezimweni eziningi, ulwelwesi lwangaphakathi ngaphambi kokufinyelela uketshezi.

Ngakho-ke, uhlobo kanye nobukhulu bomphetho wepayipi kungaba nethonya elikhulu ku-amandla esignali, ukudluliselwa kwe-acoustic, isikhala se-transducer, kanye nokuqina kokulinganisa.

1. I-Ultrasonic Signal Ihamba Kanjani Ngepayipi Elinomugqa?

Kwimitha yokugeleza ye-ultrasonic ejwayelekile ye-clamp-on, isignali ye-ultrasonic ilandela indlela efana nale:

I-Transducer → Udonga Lwepayipi → Ulwelo Lwepayipi → Ulwelo Lwepayipi → Udonga Lwepayipi → I-Transducer

Ngokungafani ne-inserting flow meter, ama-transducer awaxhumani ngqo noketshezi.

Isignali ye-ultrasonic kumele idlule ezintweni eziningana ezahlukene ngaphambi kokuba ifike kuketshezi. Into ngayinye inezakhiwo ezihlukile ze-acoustic, ngakho-ke isignali ingase ibone ukubonakaliswa, ukufiphala, kanye nokuncishiswa ezindaweni eziphakathi kwezinto.

Yingakho ulwelwesi lwamapayipi ludinga ukucatshangelwa ngesikhathi sokufakwa kwemitha yokugeleza kwe-ultrasonic.

2. Kungani Izinto Zokumboza Zibalulekile?

Izinto zokufakelwa ezihlukene zinezinhlobo ezahlukeneukuvimba kwe-acoustic kanye nesivinini somsindo.

Izinto ezivamile zokubopha amapayipi zifaka:

• I-PTFE
• Irabha
• Irabha eqinile
• Udaka lukasimende
• I-Epoxy
• Ipulasitiki
• Ezinye izembozo zokuvikela

Uma igagasi le-ultrasonic lihamba lisuka kwenye into liye kwenye, ingxenye yamandla alo ingase ibonakale esibonakalayo.

Ngokwesibonelo:

Udonga Lwepayipi → Ulwelo → Uketshezi

Ku-interface ngayinye, umehluko wezakhiwo ze-acoustic ungathinta ukuthi angakanani amandla e-ultrasonic angena ezintweni ezilandelayo.

Uma ukungafani kwe-acoustic kukhulu, amandla amaningi angabonakala futhi amandla amancane angafinyelela ku-transducer eyamukelayo.

Lokhu kungaholela ku:

Amandla esignali aphansi kanye nokulinganisa okunamandla kakhulu kwe-acoustic.

3. Kungani Ubukhulu Bendwangu Bubalulekile?

Ubukhulu bendwangu nakho kubalulekile.

Ulwelwesi oluncane lungaba nomphumela olinganiselwe, kuyilapho ulwelwesi olujiyile lungandisa kakhulu ubude bendlela ye-acoustic ngokusebenzisa izinto zolwelwesi.

Njengoba isignali ye-ultrasonic ihamba ngaphakathi kwendwangu, ingxenye yamandla ayo ingancishiswa.

Ngakho-ke, isimo sokulinganisa sithonywa yi:

Izinto Zokumboza + Ubukhulu Bendwangu + Izakhiwo Zomsindo

Ngenxa yalesi sizathu, amapayipi amabili anobubanzi obufanayo kanye nezinto zangaphandle ezifanayo angase aziphathe ngendlela ehlukile uma izinhlaka zawo zangaphakathi zihlukile.

Ngokwesibonelo:

Ipayipi lensimbi yekhabhoni elingenayo i-lining

futhi

Ipayipi lensimbi yekhabhoni elinomugqa werabha ojiyile

kungaba nezici zokudlulisa ze-ultrasonic ezihluke kakhulu.

4. Kungani Izendlalelo Zenjoloba Nezepulasitiki Zingaba Yinselele?

Ezinye izinto zokwakheka kwendwangu ezithambile noma ezinesivinini esiphansi zingenza ukulinganisa kwe-ultrasonic okubambayo kube nzima kakhulu.

Izibonelo zifaka phakathi ezithile:

• Izembozo zerabha
• Izembozo ze-PTFE
• Ama-lining epulasitiki

Igagasi le-ultrasonic lingase lizwe ukuncishiswa okukhulu noma ukubonakaliswa lapho lidlula kulezi zinto.

Lokhu kungaholela ku:

• Amandla esignali ancishisiwe
• Ubunzima obandayo ekutholakaleni kwesignali
• Ububanzi obuncane besikhala se-transducer esifanele
• Ukuzwela okwengeziwe ezimweni zokufakwa

Lokhu akusho ukuthi amapayipi anezinsika awakwazi ukukalwa.

Kunalokho, imitha yokugeleza idinga ukukhethwa kahle futhi ihlelwe ngokuvumelana nezimo zangempela zamapayipi kanye nolwelwesi.

5. Ukufakwa Kwamapayipi Kuthinta Kanjani Isikhala Se-Transducer?

Kumamitha okugeleza e-ultrasonic acindezelwayo, isikhala se-transducer sivame ukubalwa ngokusekelwe kumapharamitha amaningana, kufaka phakathi:

• Ububanzi bepayipi
• Ubukhulu bodonga lwepayipi
• Izinto zombhobho
• Izinto zokufaka ulwelwesi
• Ubukhulu bendwangu
• Uhlobo loketshezi
• Izinga lokushisa loketshezi
• Ijubane le-Ultrasonic ngokusebenzisa izinto ezahlukene

Ngakho-ke, uma ulwazi lwe-lining olufakwe ku-flow meter lungalungile, isikhala se-transducer esibaliwe singase singabi yiphutha.

Isibonelo, uma ipayipi langempela linomugqa werabha ongu-5 mm kodwa ithuluzi lihlelwe njengepayipi lensimbi elingafakwanga umugqa, indlela ye-acoustic ebaliwe ingase ingahambisani kahle nesakhiwo sepayipi langempela.

Lokhu kungenza ukutholwa kwesignali kube nzima kakhulu futhi kungathinta ukusebenza kokulinganisa.

6. Ingabe i-Flow Meter ingaba nesignali eqinile epayipini elinomugqa?

Yebo.

Ipayipi elinezingqimba akusho ngokuzenzakalelayo ukuthi isignali ye-ultrasonic izoba buthakathaka.

Amandla esignali angempela ancike emphumeleni ohlangene we:

Izinto Zombhobho + Ubukhulu Bodonga + Ulwelo + Umshini Wokudlulisa + Ukufakwa

Ukufakwa okuklanywe kahle epayipini elinophahla kusengakwazi ukunikeza isignali ye-ultrasonic eqinile neqinile.

Ngakho-ke, ukuba khona kolwelwesi akufanele kuthathwe njengophawu oluzenzakalelayo lokuthi ukulinganiswa kwe-ultrasound kwe-clamp-on akufanelekile.

7. Amabhamuza Omoya Angayenza Kanjani Inkinga Ibe Yimbi Kakhulu?

Amapayipi anezingqimba angaphinde aveze enye inkinga engaba khona: ukunqwabelana komoya.

Uma ipayipi lingagcwalisiwe ngokuphelele, noma uma kukhona amabhamuza omoya oketshezini, isignali ye-ultrasonic ingancishiswa kakhulu noma ihlakazeke.

Isimo esihlanganisiwe salokhu:

Ulwelwesi olujiyile + Amabhamuza omoya + Ukuhlanganiswa okubi

kungenza ukudluliselwa kwesignali ye-ultrasonic kube nzima kakhulu.

Ngakho-ke, indawo yokufaka kufanele ikhethwe kahle ku-ingxenye yamapayipi egcwele ngokuphelele, kude nezindawo lapho umoya ungaqongelela khona.

8. Onjiniyela Kufanele Bayihlole Kanjani Ipayipi Elinomugqa?

Ngaphambi kokufaka i-clamp-on ultrasonic flow meter, kutuswa ukuthi uqoqe ulwazi olulandelayo:

1. Ububanzi obungaphandle kwepayipi
2. Ubukhulu bodonga lwepayipi
3. Izinto zombhobho
4. Izinto zokufaka ulwelwesi
5. Ubukhulu bendwangu
6. Uhlobo loketshezi
7. Izinga lokushisa loketshezi
8. Ijubane lokugeleza elilindelekile
9. Isimo sepayipi
10. Ubude bepayipi eliqondile elitholakalayo

Lolu lwazi luvumela i-flow meter ukuthi inqume ukucushwa kwe-acoustic okufaneleke kakhulu kanye nesikhala se-transducer.

Ngezinhlelo zokusebenza ezinzima, ukuhlolwa kwangempela endaweni nakho kungaba usizo ngaphambi kokufakwa kokugcina.

9. Yiziphi Izimpawu Ezivamile Zenkinga Ehlobene Nokugoba Kwesikhumba?

Inkinga ye-acoustic ehlobene ne-lining ingase ivele kanje:

• Amandla esignali aphansi
• Amandla esignali angazinzile
• Ubunzima bokuthola isignali ye-ultrasonic
• Ukufundwa kokugeleza okungalungile noma okungazinzile
• Ukulahleka njalo kwesiginali
• Ukuzwela okunamandla endaweni ye-transducer

Nokho, lezi zimpawu azisho ukuthi ulwelwesi ngokwalo yilona kuphela oluyimbangela.

Izimpawu ezifanayo zingavela naku:

• Ukuhlanganiswa kwe-transducer okungekuhle
• Isikhala esingalungile se-transducer
• Ubukhulu bodonga lwepayipi obuningi kakhulu
• Amabhamuza omoya
• Amapharamitha epayipi angalungile
• Ukugqwala kobuso bepayipi
• Ukudlidliza kwepayipi

Ngakho-ke, ukuxazulula izinkinga kufanele kucatshangelwe yonke indlela ye-acoustic kunokugxila ku-lining kuphela.

Ukufakwa kwamapayipi kuthinta ukulinganiswa kokugeleza kwe-ultrasonic okubambekayo ngoba isignali ye-ultrasonic kumele idluleudonga lwamapayipi kanye nolwelwesi ngaphambi kokungena oketshezini.

Izinto zokwemboza kanye nobukhulu kungathinta ukudluliselwa kwe-acoustic, ukuncishiswa kwesignali, ukubonakaliswa, kanye nesikhala esidingekayo se-transducer.

Izici ezibalulekile zingafingqwa kanje:

Izinto Zombhobho + Ubukhulu Bodonga + Izinto Zokumboza + Ubukhulu Bendwangu + Izakhiwo Zoketshezi → Ukudluliselwa Kwezwi → Ikhwalithi Yesignali → Ukuqina Kokulinganisa

Ngakho-ke, lapho ukhetha futhi ufaka imitha yokugeleza ye-ultrasonic ebambayo, ulwelwesi lwamapayipi kufanele luhlale lubhekwa njengengxenye ebalulekile yendlela yokulinganisa i-acoustic.

Ipayipi elinezingqimba alivimbeli ngempela ukulinganiswa kwe-ultrasound, kodwaIzinto zokwemboza kanye nobukhulu kumele kucatshangelwe kahle ngesikhathi sokukhetha imitha yokugeleza, ukucushwa kwamapharamitha, kanye nokufakwa kwe-transducer.
