Namita kwararar ultrasonic na lokacin wucewar matsawa-kan, ƙarfin sigina yana ɗaya daga cikin mahimman sigogin ganewar asali. Duk da haka, akwai rashin fahimta gama gari:

Ƙarfin sigina mai girma ba lallai bane yana nufin daidaiton ma'auni mai girma, kuma ƙarancin ƙarfin sigina ba lallai bane yana nufin cewa na'urar auna kwarara tana da matsala.

Ƙarfin siginar yana nuna mana yadda siginar ultrasonic ke tafiya ta cikin bututu da ruwa yadda ya kamata da kuma yadda na'urar transducer ta karɓe ta da kyau.

1. Menene Ƙarfin Sigina?

A cikin sauƙi,Ƙarfin sigina yana nuna ƙarfin siginar ultrasonic da aka karɓa ta hanyar mitar kwarara.

Don na'urar auna kwararar ultrasonic, hanyar sauti kamar haka:

Mai Canzawa → Bangon Bututu → Rufi → Ruwa → Rufi → Bangon Bututu → Mai Canzawa

Mai watsawa yana samar da siginar ultrasonic, wanda ke ratsa bangon bututu da ruwa kafin ya isa ga na'urar watsawa mai karɓa.

Idan aka watsa kuzarin sauti ba tare da asara ba, siginar da aka karɓa za ta fi ƙarfi. Idan siginar ta fuskanci raguwar sauti, ko kuma warwatsewa, siginar da aka karɓa za ta yi rauni.

2. Waɗanne Abubuwa Ne Ke Shafar Ƙarfin Sigina?

Abubuwa da yawa na iya yin tasiri sosai ga siginar ultrasonic da aka karɓa.

2.1 Kayan Bututu

Kayan bututu daban-daban suna da fasaloli daban-daban na sauti.

Misalan gama gari sun haɗa da:

• Karfe mai carbon
• Bakin karfe
• Simintin ƙarfe
• PVC
• HDPE
• Bututun da aka yi wa siminti

Makamashin Ultrasonic yana aiki daban-daban lokacin da yake wucewa ta cikin kayayyaki daban-daban. Saboda haka, mitar kwarara iri ɗaya na iya nuna ƙarfin sigina daban-daban lokacin da aka sanya shi akan nau'ikan bututu daban-daban.

2.2 Kauri Bangon Bututu

Kauri bangon bututu yana da mahimmanci musamman don auna kwararar ultrasonic mai mannewa.

Gabaɗaya, kauri bangon bututu, girman adadin kayan da siginar ultrasonic dole ne ta ratsa, wanda zai iya ƙara rage sautin sauti.

Wannan zai iya zama da mahimmanci musamman ga waɗannan:

Bututun bango mai kauri, babba-diamita

Saboda haka, girman bututun kawai bai isa ba don zaɓar na'urar auna kwararar ultrasonic.

Misali, maimakon bayar da kawai:

Girman bututu: DN500

ya fi amfani a samar da:

Kayan bututu + Diamita na waje + Kauri a bango + Kayan rufi

2.3 Rufin Bututu

Rufin bututu na iya yin tasiri mai mahimmanci akan ƙarfin sigina.

Kayan da aka fi amfani da su wajen yin rufi sun haɗa da:

• PTFE
• Roba
• Siminti
• Epoxy
• Roba

Siginar ultrasonic na iya buƙatar wucewa ta:

Mai Canzawa → Bangon Bututu → Rufi → Ruwa

Idan halayen sautin murfin ya bambanta sosai da na bututu da ruwa, ƙarin asarar sauti na iya faruwa.

Saboda haka, sanin cewa bututu "ƙarfe" ba koyaushe yake isa ba. Ya kamata a yi la'akari da nau'in da kauri na rufin ciki.

3. Me yasa kumfa na iska ke rage ƙarfin sigina?

Kumfa na iska yana ɗaya daga cikin abubuwan da suka fi haifar da raunin siginar ultrasonic ko rashin kwanciyar hankali.

Saboda iskar gas da ruwa suna da halaye daban-daban na sauti, kumfa na iya warwatsewa da kuma nuna raƙuman ultrasonic.

Ba tare da kumfa mai mahimmanci na iska ba:

Siginar Ultrasonic → Ruwa → Mai karɓar na'urar watsawa

Tare da kumfa iska:

Siginar Ultrasonic → Kumfa → Watsawa/Tunani → Asarar kuzari → Siginar da aka karɓa mai rauni

Sakamakon haka, kumfa mai yawa na iya haifar da:

• Rage ƙarfin sigina
• Karatun kwarara mara tsari
• Asarar siginar lokaci-lokaci
• Rashin daidaiton ma'auni

Saboda haka, idan ƙarfin sigina ya ragu ba zato ba tsammani, injiniyan bai kamata ya duba na'urorin transducers kawai ba, har ma ya binciki ko iska tana cikin bututun.

4. Haɗin Transducer shima yana da matuƙar muhimmanci

Ga na'urar auna kwararar ultrasonic, na'urar transducer ba ta taɓa ruwan kai tsaye ba. Dole ne siginar ultrasonic ta ratsa ta bangon bututu.

Ana iya sauƙaƙe hanyar haɗin gwiwa kamar haka:

Mai Canzawa → Haɗaɗɗen Haɗaɗɗen → Bangon Bututu

Rashin haɗin kai mai kyau zai iya rage ƙarfin sigina sosai.

Dalilan da suka fi yawa sun haɗa da:

• Rashin isasshen mahaɗin haɗawa
• Haɗin mara daidaituwa
• Tsatsa ko tsatsa a saman bututun
• Fenti ko shafi mai kauri
• Taurin saman bututu
• Masu sassauƙan transducers
• Masu canza wutar lantarki waɗanda suka canza daga matsayinsu na asali

Saboda haka, shiri mai kyau na saman da kuma kyakkyawar hulɗa ta injiniya tsakanin na'urar transducer da bututu suna da mahimmanci don ingantaccen watsawa ta ultrasonic.

5. Shin Ƙarfin Sigina Mai Girma Yana Nufin Daidaito Mai Girma?

Ba lallai ba ne.

Wannan yana ɗaya daga cikin mahimman abubuwan da ya kamata a fahimta.

Ƙarfin sigina yana gaya mana musamman:

"Shin na'urar auna kwarara za ta iya karɓar siginar ultrasonic mai ƙarfi sosai?"

Daidaiton aunawa, a gefe guda, yana tambaya:

"Yaya kusancin kwararar da aka auna da ainihin kwararar?"

Waɗannan abubuwa biyu ne daban-daban.

Misali:

Shari'a A

Ƙarfin Sigina: Babba

Amma ana sanya na'urorin transducers a wuri mara kyau kuma yanayin kwararar bayanai ya lalace sosai.

→ Siginar na iya zama mai ƙarfi, amma ma'aunin na iya samun kuskure.

Shari'a ta B

Ƙarfin Sigina: Matsakaici

Amma an shigar da na'urorin transducers daidai, yanayin bututun ya dace, kuma siginar ta tsaya cak.

→ Mita mai kwarara har yanzu tana iya cimma kyakkyawan aikin aunawa.

Saboda haka:

Babban Ƙarfin Sigina ≠ Babban Daidaito

6. Yaya Ƙasa Take Ƙasa?

Babu wani ƙimar ƙarfin sigina na duniya da za a iya amfani da shi ga kowane mitar kwararar ultrasonic.

Masana'antun daban-daban na iya fayyace da kuma nuna ƙarfin sigina ta hanyoyi daban-daban, misali:

• Ƙarfin Sigina %
• Ƙarfin Sigina a cikin dB
• Ingancin Sigina
• SNR
• Matsayin Sigina da aka Karɓa

Waɗannan sigogi suna da alaƙa, amma suna da alaƙaba lallai ba ne a yi kamanceceniya kai tsaye tsakanin masana'antun ko samfura daban-daban.

Don takamaiman na'urar auna kwarara, ya kamata a yi amfani da littafin jagorar masana'anta da kuma ma'anar kayan aikin a matsayin ma'auni.

7. Ƙarfin Sigina idan aka kwatanta da SNR

Don ƙarin fahimtar juna, yana da mahimmanci a rarrabe tsakanin waɗannan.Ƙarfin SiginadagaSNR (Rabon Sigina zuwa Ƙara).

Ƙarfin Siginagalibi yana bayyana:

Yaya ƙarfin siginar ultrasonic da aka karɓa yake.

SNRya bayyana:

Ƙarfin siginar mai amfani idan aka kwatanta da hayaniyar bango.

Misali, na'urar auna kwararar ruwa na iya karɓar sigina mai ƙarfi, amma idan hayaniyar lantarki ko ta injina ma tana da yawa, SNR na iya zama mara kyau.

Saboda haka, lokacin da kayan aikin ya bayar da sigogi kamar:

Ƙarfin Sigina + SNR + Ingancin Sigina

Ya kamata a kimanta su tare.

8. Ta Yaya Za A Iya Amfani da Ƙarfin Sigina Don Magance Matsaloli?

Hanyar magance matsala mai amfani ita ce a lura da duka biyunmatakin da kwanciyar hankalina siginar.

Sigina mai ƙarfi kuma mai karko

Wannan gabaɗaya yana nuna cewa:

• Transducers ɗin suna da alaƙa mai kyau
• Hanyar sauti ta karɓuwa
• Siginar karɓa tana da ƙarfi

Duk da haka, har yanzu ana buƙatar kimanta daidaiton ma'auni daban.

Sigina mai rauni sosai

Duba waɗannan:

1. Shigar da na'urar transducer
2. Haɗin mahaɗi
3. Yanayin saman bututu
4. Kauri bango na bututu
5. Rufin bututu
6. Kumfan iska
7. Ko bututun ya cika gaba ɗaya
8. Tazarar na'urar transducer
9. Zaɓin na'urar juyawa
10. Bututu da sigogin ruwa da aka shigar cikin mitar kwarara

Ƙarfin sigina yana raguwa ba zato ba tsammani

Kula da hankali musamman ga:

• Kumfa iska suna shiga bututun
• Masu sassauƙan transducers
• Lalacewar haɗin gwiwa
• Canje-canje a yanayin aiki
• Muhimman canje-canje a yanayin zafi na ruwa
• Girgizar bututu

9. Ƙarfin Sigina Yana Kama da Alamar Lafiyar Jiki

A ƙarshe,Ya kamata a ɗauki ƙarfin sigina a matsayin alamar ganewar sauti maimakon alamar daidaito kai tsaye.

Yana taimakawa wajen amsa tambayar:

"Shin siginar ultrasonic tana tafiya ta cikin bututu da ruwa kuma ana karɓar ta yadda ya kamata?"

Ba, da kansa, amsa ba ce:

"Shin ma'aunin kwararar daidai ne?"

Kyakkyawan kimantawa ya kamata ya yi la'akari da abubuwa da yawa:

Ƙarfin Sigina + Ingancin SNR/Sigina + Shigar da na'urar juyawa + Yanayin Bututu + Yanayin Ruwa + Bayanin Gudawa + Daidaitawa

Saboda haka, a cikin aikace-aikacen injiniyan aiki,Ƙarfin sigina yana da amfani musamman don tabbatar da shigarwa, gyara matsala, da kuma sa ido kan yanayin sautin tsarin aunawa - ba a matsayin takamaiman takamaiman don daidaiton ma'auni ba.
