Ukufakwa kwepayipi yinto ebalulekileyo ekufuneka iqwalaselwe xa ufaka i-imitha yokuhamba kwe-ultrasonic ebambekayoNangona ii-transducers zifakwe ngaphandle kombhobho, isignali ye-ultrasonic kufuneka idlule eludongeni lombhobho, kwaye kwiimeko ezininzi, i-lining yangaphakathi ngaphambi kokuba ifikelele kulwelo.

Ngoko ke, uhlobo kunye nobukhulu bomgca wepayipi bunokuba nefuthe elikhuluamandla esignali, uthumelo lwe-acoustic, isithuba se-transducer, kunye nokuzinza komlinganiselo.

1. Ihamba Njani I-Ultrasonic Signal Ngepayipi Enemigca?

Kwimitha yokuhamba kwe-ultrasonic eqhelekileyo ye-clamp-on, isignali ye-ultrasonic ilandela indlela efana nale:

I-Transducer → Udonga lweMibhobho → I-Lining yeMibhobho → Ulwelo → I-Lining yeMibhobho → Udonga lweMibhobho → I-Transducer

Ngokungafaniyo nesixhobo sokulinganisa ukuhamba kwamanzi esifakiweyo, ii-transducers aziqhagamshelani ngqo nolwelo.

Isignali ye-ultrasonic kufuneka ihambe kwizinto ezahlukeneyo ngaphambi kokuba ifikelele kulwelo. Isixhobo ngasinye sineempawu ezahlukeneyo ze-acoustic, ngoko ke isignali inokuba namava okubonakalisa, ukurhawuzelelwa, kunye nokuncitshiswa kwiindawo eziphakathi kwezinto.

Yingakho kufuneka kuqwalaselwe ukufakwa kwe-lining yepayipi ngexesha lokufakwa kwe-ultrasonic flow meter.

2. Kutheni Izinto Ezisetyenziswa Ngaphakathi Zibalulekile?

Izinto ezahlukeneyo zelineni zahlukileukuthintela i-acoustic kunye nesantya sesandi.

Izinto eziqhelekileyo zokufakelwa kwepayipi ziquka:

• I-PTFE
• Irabha
• Irabha eqinileyo
• Udaka lwesamente
• I-Epoxy
• Iplastiki
• Ezinye iingubo zokukhusela

Xa igagasi le-ultrasound lihamba lisuka kwenye into liye kwenye, inxalenye yamandla alo inokubonakaliswa kwindawo ejonge kuyo.

Umzekelo:

Udonga lweMibhobho → Ingaphakathi → Ulwelo

Kwi-interface nganye, umahluko kwiipropati ze-acoustic unokuchaphazela ukuba ingakanani amandla e-ultrasonic angena kwisixhobo esilandelayo.

Ukuba ukungalingani kwe-acoustic kubalulekile, amandla amaninzi anokubonakaliswa kwaye amandla amancinci anokufikelela kwi-transducer efumanayo.

Oku kunokubangela oku:

Amandla esignali aphantsi kunye nomlinganiselo we-acoustic onzima ngakumbi.

3. Kutheni Ubukhulu Belayini Bubalulekile?

Ubukhulu belineni bubalulekile.

I-lining encinci inokuba nefuthe elilinganiselweyo, ngelixa i-lining etyebileyo inokunyusa kakhulu ubude bendlela ye-acoustic ngokusebenzisa izinto ze-lining.

Njengoko isignali ye-ultrasound ihamba ngaphakathi kwe-lining, inxalenye yamandla ayo inokuncipha.

Ngoko ke, imeko yokulinganisa ichaphazeleka yi:

Izinto zokugquma + Ubukhulu beLining + Iipropati zeAcoustic

Ngenxa yesi sizathu, imibhobho emibini enobubanzi obufanayo kunye nezinto zangaphandle ezifanayo inokuziphatha ngokwahlukileyo ukuba ii-linings zayo zangaphakathi zahlukile.

Umzekelo:

Umbhobho wentsimbi yekhabhoni ongenalo ulwelo

kwaye

Umbhobho wentsimbi yekhabhoni onomphetho wezarha otyebileyo

inokuba neempawu zokudluliselwa kwe-ultrasonic ezahlukileyo kakhulu.

4. Kutheni iilaphu zerabha kunye neplastiki zingaba nzima?

Ezinye izinto ze-lining ezithambileyo okanye ezikhawulezayo ngesandi esiphantsi zinokwenza kube nzima ngakumbi ukulinganisa i-clamp-on ultrasonic.

Imizekelo ibandakanya ezithile:

• Iilining zerabha
• Iilinki ze-PTFE
• Iilining zeplastiki

Amaza e-ultrasonic anokuba nokuncitshiswa okukhulu okanye ukubonakaliswa xa edlula kwezi zinto.

Oku kunokukhokelela ku:

• Amandla esignali anciphileyo
• Ubunzima obandayo ekufumaneni isignali
• Uluhlu oluncinci lwesithuba esifanelekileyo se-transducer
• Uvakalelo olungakumbi kwiimeko zofakelo

Oku akuthethi ukuba imibhobho eneengcango ayinakulinganiswa.

Kunoko, imitha yokuhamba kwamanzi kufuneka ikhethwe ngokufanelekileyo kwaye icwangciswe ngokweemeko zombhobho kunye ne-lining.

5. I-Pipe Lining iyichaphazela njani i-Transducer?

Kwimitha yokuhamba kwe-ultrasonic ebanjiweyo, isithuba se-transducer sidla ngokubalwa ngokusekelwe kwiiparameter ezahlukeneyo, kuquka:

• Ububanzi bepayipi
• Ubukhulu bodonga lombhobho
• Izinto zombhobho
• Izinto zokugquma
• Ubukhulu belineni
• Uhlobo lolwelo
• Ubushushu bolwelo
• Isantya se-ultrasonic ngokusebenzisa izixhobo ezahlukeneyo

Ngoko ke, ukuba ulwazi lwe-lining olufakwe kwi-flow meter aluchanekanga, isithuba se-transducer esibaliweyo naso sisenokungachanekanga.

Umzekelo, ukuba umbhobho wokwenyani une-5 mm ngerabha kodwa isixhobo silungiselelwe njengombhobho wentsimbi ongafakwanga migca, indlela ye-acoustic ebaliweyo isenokungahambelani ngokuchanekileyo nolwakhiwo lombhobho wokwenyani.

Oku kungenza kube nzima ukufumana isignali kwaye kunokuchaphazela ukusebenza kokulinganisa.

6. Ngaba i-Flow Meter ingaba neSignali eyomeleleyo kwiPipe eneentambo?

Ewe.

Umbhobho ofakwe ngaphakathi awuthethi ngokuzenzekelayo ukuba isignali ye-ultrasonic iya kuba buthathaka.

Amandla esignali yokwenyani axhomekeke kwisiphumo esidibeneyo se:

Izinto zombhobho + Ubukhulu bodonga + Ilayini + Ulwelo + I-Transducer + Ukufakelwa

Ufakelo oluyilwe kakuhle kumbhobho ofakwe uphahla lusenokubonelela ngesignali ye-ultrasonic eqinileyo neqinileyo.

Ngoko ke, ubukho bomgca akufanele buthathwe njengophawu oluzenzekelayo lokuba umlinganiselo we-clamp-on ultrasound awufanelekanga.

7. Amaqamza omoya angayenza njani ingxaki ibe mbi ngakumbi?

Imibhobho eneengcango ingabonakalisa enye ingxaki enokubakho: ukuqokelelwa komoya.

Ukuba umbhobho awuzaliswanga ngokupheleleyo, okanye ukuba kukho amaqamza omoya kulwelo, isignali ye-ultrasonic inokuncipha kakhulu okanye isasazeke.

Imeko edibeneyo ye:

Ingaphakathi elingqindilili + Amaqamza omoya + Ukudibanisa okubi

kunokwenza ukuhanjiswa kwesignali ye-ultrasonic kube nzima ngakumbi.

Ngoko ke, indawo yokufakela kufuneka ikhethwe kakuhle kwiicandelo lepayipi elizaliswe ngokupheleleyo, kude neendawo apho umoya unokuqokelelana khona.

8. Iinjineli Zifanele Ziyihlole Njani Ipayipi Enemigca?

Ngaphambi kokufaka i-clamp-on ultrasonic flow meter, kucetyiswa ukuba uqokelele olu lwazi lulandelayo:

1. Ububanzi obungaphandle kombhobho
2. Ubukhulu bodonga lombhobho
3. Izinto zombhobho
4. Izinto zokugquma
5. Ubukhulu belineni
6. Uhlobo lolwelo
7. Ubushushu bolwelo
8. Isantya sokuhamba esilindelekileyo
9. Imeko yombhobho
10. Ubude bombhobho othe tye obufumanekayo

Olu lwazi luvumela i-flow meter ukuba imisele ulungelelwaniso olufanelekileyo lwe-acoustic kunye nesithuba se-transducer.

Kwiinkqubo ezinzima, uvavanyo lwangempela kwindawo lunokuba luncedo ngaphambi kokufakwa kokugqibela.

9. Ziziphi Iimpawu Eziqhelekileyo Zengxaki Enxulumene Nezithende?

Ingxaki ye-acoustic enxulumene ne-lining ingabonakala ngolu hlobo:

• Amandla esignali aphantsi
• Amandla esignali angaqinisekanga
• Ubunzima bokufumana isignali ye-ultrasonic
• Ukufundwa kokuhamba kwamanzi okungachanekanga okanye okungazinzanga
• Ukulahleka rhoqo kwesiginali
• Uvakalelo oluqinileyo kwindawo ye-transducer

Nangona kunjalo, ezi mpawu azithethi ukuba i-lining ngokwayo yimbangela kuphela.

Iimpawu ezifanayo zinokubangelwa nazi:

• Ukudibanisa i-transducer okungekho semgangathweni
• Isithuba esingalunganga se-transducer
• Ubukhulu bodonga lombhobho obugqithisileyo
• Amaqamza omoya
• Iiparameter zepayipi ezingachanekanga
• Ukugqwala komphezulu wombhobho
• Ukungcangcazela kwepayipi

Ngoko ke, ukusombulula iingxaki kufuneka kuqwalaselwe yonke indlela ye-acoustic endaweni yokugxila kwi-lining yodwa.

Umgca wepayipi uchaphazela ukulinganiswa kokuhamba kwe-ultrasound kuba isignali ye-ultrasonic kufuneka idluleudonga lombhobho kunye ne-lining ngaphambi kokungena kulwelo.

Izinto ezikwi-lining kunye nobukhulu zinokuchaphazela ukuhanjiswa kwe-acoustic, ukuncitshiswa kwesignali, ukubonakaliswa, kunye nesithuba esifunekayo se-transducer.

Izinto eziphambili zingashwankathelwa ngolu hlobo:

Izinto Zombhobho + Ubukhulu Bodonga + Izinto Zomphetho + Ubukhulu Bengubo + Iimpawu Zolwelo → Ukudluliselwa Kwesandi → Umgangatho Wesignali → Uzinzo Lokulinganisa

Ngoko ke, xa ukhetha kwaye ufaka i-clamp-on ultrasonic flow meter, i-lining yombhobho kufuneka ihlale ithathwa njengenxalenye ebalulekileyo yendlela yokulinganisa i-acoustic.

Umbhobho ofakwe ngaphakathi awuthinteli ukulinganiswa kwe-ultrasound, kodwaIzinto ze-lining kunye nobukhulu kufuneka ziqwalaselwe ngokuchanekileyo ngexesha lokukhetha i-flow meter, ulungiselelo lweeparameter, kunye nokufakwa kwe-transducer.
