Izinto Ezichaphazela Ukusebenza Kweemitha Zamanzi Ze-Ultrasonic

1. Izinto ezinxulumene nolwelo

Amaqamza egesi emanzini

Amaqamza egesi yingxaki eqhelekileyo kwiinkqubo zokubonelela ngamanzi.ukuhamba kwamanzingokusebenzisa imibhobho, ingakumbi kwiimeko apho uxinzelelo lwamanzi lutshintsha okanye kukho umthombo weegesi ezinyibilikisiweyo, iibhamu zegesi zinokwenziwa. Amaza e-Ultrasonic asasazeka emanzini ngokungcangcazela iimolekyuli zamanzi. Iibhamu zegesi, ezine-acoustic impedance yazo eyahlukileyo kakhulu xa kuthelekiswa namanzi, zisebenza njengee-reflectors ezinamandla kunye nezisasazi zamaza e-ultrasonic. Xa isignali ye-ultrasonic idibana nala mabhamu egesi, inxalenye enkulu yamandla ibonakaliswa emva kwangethuba okanye isasazeke kwiindlela ezahlukeneyo. Oku kuphazamisa ukusasazeka okuqhelekileyo kwesignali ye-ultrasonic phakathi komthumeli kunye nommkeli kwimitha yamanzi. Ngenxa yoko, imitha isenokungayichazi kakuhle isignali, nto leyo ekhokelela ekubalweni okungachanekanga kwesantya sokuhamba kwamanzi kunye nokufundwa okungachanekanga kokusetyenziswa kwamanzi.

Ukungcola kunye nokungcola

Ekuhambeni kwexesha, imibhobho yamanzi iqokelela inkunkuma, umhlwa, kunye nezinye izinto ezingcolileyo. Ezi zinto zinokuhlala eludongeni lwangaphakathi lwemibhobho kwaye, kwimeko yeemitha zamanzi ze-ultrasonic, zinokugquma umphezulu we-transducer. Inkunkuma kunye nokungcola kwi-transducer kunokunciphisa isignali ye-ultrasonic. Isignali kufuneka idlule kolu layer lwezinto ezingcolisayo ngaphambi kokuba ifike emanzini, kwaye ngeli xesha le nkqubo, amandla ayo ayancipha. Ukongeza, umphezulu orhabaxa owenziwe yinkunkuma unokubangela ukuba amaza e-ultrasound asasazeke, okwenza kube nzima kwimitha ukubona ngokuchanekileyo ixesha lokubhabha okanye i-Doppler shift (kuxhomekeke kuhlobo lweimitha yamanzi ye-ultrasonicOku kuphazamiseka komqondiso kukhokelela kwiimpazamo ekulinganiseni isantya sokuhamba kwamanzi, ekugqibeleni okubangela ukulinganiswa komthamo wamanzi ngendlela engalunganga.

2. Izinto ezinxulumene nokufakwa

Ukhetho olungalunganga lweCandelo leMibhobho

Indawo ekuyoimitha yamanzi ye-ultrasonicUkufakelwa ngaphakathi kwenethiwekhi yepayipi kubalulekile. Ukuba imitha ifakwe kwicandelo lombhobho oneprofayili yokuhamba engalinganiyo, efana nokugoba, ingqiniba, okanye ivalvu, ukuhamba kwamanzi kuyaguquguquka. Kwindlela yokuhamba eguquguqukayo, isantya samanzi siyahluka kakhulu kwicandelo elinqamlezileyo lombhobho. Iimitha zamanzi ze-Ultrasonic zenzelwe ukulinganisa isantya sokuhamba kwamanzi esiqhelekileyo. Nangona kunjalo, xa zifakwe kwindawo yokuhamba eguquguqukayo, isantya esilinganisiweyo sisenokungameli ukuhamba kwamanzi ngokubanzi kumbhobho. Umzekelo, kwi-pipe bend, amanzi akufutshane nodonga lwangaphandle lwe-bend ahamba ngokukhawuleza kunakufutshane nodonga lwangaphakathi. Ukuba imitha ye-ultrasonic ilinganisa isantya kwindawo ephenjelelwa ngakumbi ngamanzi angaphandle ahamba ngokukhawuleza, iya kuqikelela isantya sokuhamba siphela.

Ulungelelwaniso lweSensor olungalunganga

Ukulungelelaniswa ngokufanelekileyo kwee-sensors ze-ultrasonic kubalulekile ukuze kulinganiswe ngokuchanekileyo. Ii-sensors ezikwimitha yamanzi ye-ultrasonic kufuneka zilungelelaniswe ngokuchanekileyo ukuze kuqinisekiswe ukuba isignali ye-ultrasonic ihamba emanzini ngendlela eqikelelweyo. Ukuba ii-sensors zilungelelaniswe gwenxa, isignali isenokungafikeleli kwi-sensor efumanayo ngokuchanekileyo. Nokuba ukungalungelelani okuncinci kunokubangela ukuba amaza e-ultrasound ahambe kwindlela ende okanye enzima ngakumbi emanzini, nto leyo enokubangela iimpazamo ekulinganisweni kwexesha - lokubhabha okanye i-Doppler shift. Le mpazamo ibangelwa kukungalungelelani inokuqokelelana ngokuhamba kwexesha kwaye ibangele ukungangqinelani okukhulu kufundo lokusetyenziswa kwamanzi.

3. Izinto eziphathelele indalo

Utshintsho kwiqondo lobushushu

Ubushushu bunempembelelo enkulu ekusebenzeni kweemitha zamanzi ze-ultrasonic. Isantya sesandi emanzini sinxulumene ngokuthe ngqo nobushushu bawo. Njengoko ubushushu bamanzi butshintsha, isantya apho amaza e-ultrasound ahamba ngaso siyatshintsha. Iimitha zamanzi ze-ultrasonic zixhomekeke kulwazi oluchanekileyo lwesantya sesandi emanzini ukuze zibale isantya sokuhamba. Ukuba indlela yokuhlawula ubushushu kwimitha ayilinganiswanga ngokufanelekileyo okanye ayibalulekanga utshintsho olukhawulezileyo kubushushu, imitha iya kubala isantya sokuhamba ngokusekelwe kwixabiso elingachanekanga lesantya sesandi. Umzekelo, ukuba ubushushu bamanzi buyanda, isantya sesandi emanzini siyanda. Ukuba imitha ayilungiseleli olu nyuko, iya kuyithoba isantya sokuhamba kuba ithatha isantya esiphantsi sesandi.

Ukuphazamiseka kwe-Electromagnetic

Kwiindawo zanamhlanje, kukho imithombo emininzi yokuphazamiseka kwe-electromagnetic (EMI). Iimitha zamanzi ze-Ultrasonic, ezisebenzisa izinto zombane ukuvelisa nokufumana imiqondiso ye-ultrasonic, zinokuchaphazeleka yi-EMI. Imithombo ye-EMI ingabandakanya imigca yamandla ekufutshane, iimoto zombane, kunye neetransmitter zerediyo. I-EMI ingaphazamisa imiqondiso yombane ngaphakathi kwemitha yamanzi, ibangele ingxolo kwisignali ye-ultrasonic efunyenweyo. Le ngxolo inokugqwetha isignali kwaye yenze kube nzima kwiyunithi yokucubungula isignali yemitha ukuba ichonge ngokuchanekileyo iimpawu ezifanelekileyo ze-ultrasonic zokulinganisa ukuhamba kwamanzi. Ngenxa yoko, imitha yamanzi inokuvelisa ukufundwa okungachanekanga ngenxa yokuphazamiseka okuvela kwiindawo zangaphandle ze-electromagnetic.

Ukuqukumbela, ukuqinisekisa ukusebenza ngokuchanekileyo kweiimitha zamanzi ze-ultrasonic, kuyimfuneko ukuqwalasela nokujongana nezi zinto ezinxulumene nolwelo, ukufakwa, kunye nokusingqongileyo. Ngokwenza njalo, imilinganiselo yokusetyenziswa kwamanzi ethembekileyo ingafunyanwa, nto leyo ibalulekileyo kwiinkqubo zolawulo lwamanzi ezisebenzayo kunye neentlawulo.
