Kunemita yekuyerera kweultrasonic inobatirira panguva yekufambisa, simba remasaini ndeimwe yenzira dzinonyanya kubatsira pakuongorora. Zvisinei, pane kusanzwisisana kwakajairika:

Simba guru rechiratidzo harirevi kuti kuyera kwakanyatsojeka, uye simba shoma rechiratidzo harirevi kuti flow meter haina kunaka.

Simba remasaini rinonyanya kutiudza kuti masaini e ultrasonic anofamba zvakanaka sei nemupombi nemumvura uye kuti anogamuchirwa zvakanaka sei ne transducer yakasiyana.

1. Chii Chinonzi Simba reChiratidzo?

Nemashoko akareruka,simba rechiratidzo rinoratidza simba rechiratidzo che ultrasonic chinogamuchirwa ne flow meter.

Pamuchina we ultrasonic flow meter unobatidzwa ne clamp-on, nzira ye acoustic inenge iri:

Transducer → Madziro epaipi → Mupendero → Mvura → Mupendero → Madziro epaipi → Transducer

Chinotumira chinoburitsa chiratidzo che ultrasonic, icho chinofamba nepamadziro epombi nemvura chisati chasvika pa transducer inogamuchira.

Kana simba remanzwi rikapfuudzwa pasina kurasikirwa kukuru, chiratidzo chinogamuchirwa chichava chakasimba. Kana chiratidzo chikawana kudzikira kukuru, kuratidzwa, kana kupararira, chiratidzo chinogamuchirwa chichava chisina simba.

2. Ndezvipi Zvinhu Zvinokanganisa Simba reMasaini?

Zvinhu zvakawanda zvinogona kukanganisa zvikuru chiratidzo che ultrasound chinogamuchirwa.

2.1 Zvinhu zvepombi

Zvinhu zvakasiyana-siyana zvepombi zvine hunhu hwakasiyana hweacoustic.

Mienzaniso yakajairika inosanganisira:

• Simbi yekabhoni
• Simbi isina ngura
• Simbi yakakandwa
• PVC
• HDPE
• Pombi yakagadzirwa nesimende

Simba re ultrasonic rinoita zvakasiyana kana richipfuura nepakati pezvinhu zvakasiyana. Nokudaro, flow meter imwe chete inogona kuratidza simba remasaini akasiyana kana yakaiswa pamhando dzakasiyana dzemapombi.

2.2 Ukobvu hweMadziro ePombi

Ukobvu hwemadziro epombi hwakakosha zvikuru pakuyera kuyerera kwemvura inobatidzwa ne ultrasound.

Kazhinji, kana madziro epombi akakora, huwandu hwezvinhu izvo chiratidzo che ultrasonic chinofanira kupfuura nepakati pacho hunowedzera, izvo zvinogona kuwedzera acoustic attenuation.

Izvi zvinogona kuva zvakakosha zvikuru kune:

Mapaipi makuru, ane dhayamita yakakora

Saka, saizi yepombi chete haikwani pakusarudza mita yekuyerera kwemvura ye ultrasonic.

Semuenzaniso, pane kungopa chete:

Saizi yepombi: DN500

zvinobatsira zvikuru kupa:

Zvinhu zvepaipi + dhayamita yekunze + Ukobvu hwemadziro + Zvinhu zvemukati

2.3 Kuisa mapaipi

Kuiswa kwepombi kunogona kuva nemigumisiro yakakura pakusimba kwechiratidzo.

Zvinhu zvakajairika zvemachira zvinosanganisira:

• PTFE
• Rabha
• Simende
• Epoxy
• Purasitiki

Chiratidzo che ultrasound chingada kupfuura nepakati pe:

Transducer → Madziro epaipi → Mucheka → Mvura

Kana hunhu hwe acoustic hwe lining hwakasiyana zvakanyanya nehwepaipi nemvura, kurasikirwa kwe acoustic kunogona kuitika.

Saka, kuziva kuti pombi "isimbi" hakukwani nguva dzose. Rudzi uye ukobvu hwemukati memukati zvinofanirawo kufungwa nezvazvo.

3. Sei Mabhurumu Emhepo Achideredza Simba Rechiratidzo?

Mafuro emhepo ndeimwe yezvikonzero zvinowanzo kukonzera zviratidzo zve ultrasound zvisina simba kana kuti zvisina kugadzikana.

Nekuti gasi nemvura zvine hunhu hwakasiyana kwazvo hweacoustic, mabubble anogona kupararira uye kuratidza mafungu e ultrasound.

Pasina mabubble emhepo akakosha:

Chiratidzo cheUltrasonic → Mvura → Transducer inogamuchira

Nemabhurumu emhepo:

Chiratidzo cheUltrasonic → Mabhurumu → Kupararira/Kufungisisa → Kurasikirwa nesimba → Chiratidzo chisina simba chakagamuchirwa

Nekuda kweizvozvo, mabhurumu emhepo akawandisa anogona kukonzera:

• Simba rechiratidzo rakaderedzwa
• Kuverengwa kwemvura isina kugadzikana
• Kurasikirwa kwechiratidzo chenguva pfupi
• Kusagadzikana kwekuyera kwakashata

Saka, kana simba remasaini radzikira kamwe kamwe, mainjiniya haafanire kungotarisa ma transducer chete asiwo kuongorora kana mhepo iri mupombi.

4. Kubatanidza Transducer Kwakakoshawo

Kana iri ultrasound flow meter inobatidzwa ne clamp-on, transducer haibate mvura zvakananga. Chiratidzo che ultrasonic chinofanira kupfuura nepamadziro epombi.

Nzira yekubatanidza inogona kurerutswa seizvi:

Transducer → Coupling Compound → Masvingo ePombi

Kubatana kusina kunaka kunogona kuderedza simba rechiratidzo zvakanyanya.

Zvikonzero zvakajairika zvinosanganisira:

• Kusakwana kwekubatanidza chinhu
• Kubatana kusina kuenzana
• Ngura kana ngura pamusoro pepombi
• Pendi gobvu kana kuti pendi
• Pombi isina kunaka
• Matransducer akasununguka
• Matransuctor akachinja kubva panzvimbo yawo yekutanga

Kugadzirira zvakanaka pamusoro pechinhu uye kubatana kwakanaka kwemuchina pakati petransducer nepombi zvakakosha kuti transmission ye ultrasonic ienderane nezvinodiwa.

5. Simba reMasaini Akakwirira Rinoreva Kururama Kwakanyanya Here?

Hazvisi hazvo.

Iyi ndeimwe yepfungwa dzakakosha kunzwisisa.

Simba rechiratidzo rinonyanya kutiudza kuti:

"Ko flow meter inogona kugamuchira chiratidzo chakasimba che ultrasound here?"

Kururama kwekuyera, kune rumwe rutivi, kunobvunza kuti:

"Kuyerera kwemvura kwakayerwa kwaswedera pedyo zvakadii nekufamba kwemvura chaiko?"

Izvi zvinhu zviviri zvakasiyana.

Semuyenzaniso:

Nyaya A

Simba reChiratidzo: Yakakwirira

Asi ma transducers akaiswa panzvimbo isina kunaka uye mafambiro emvura akakanganisika zvakanyanya.

→ Chiratidzo chingave chakasimba, asi chiyero chinogona kunge chiine chikanganiso.

Nyaya B

Simba reChiratidzo: Rine Pakati Nepakati

Asi ma transducer akaiswa nemazvo, mamiriro epombi akakodzera, uye chiratidzo chakagadzikana.

→ Chiyero chemvura chinogona kuramba chichikwanisa kuyera zvakanaka.

Saka:

Simba reChiratidzo Chakakwirira ≠ Kururama Kwakanyanya

6. Kuderera Kwakanyanya Kuderera Zvakadini?

Hapana simba rechiratidzo rinowanikwa pasi rose rinogona kushandiswa pa ultrasound flow meter yega yega.

Vagadziri vakasiyana vanogona kutsanangura uye kuratidza simba rechiratidzo zvakasiyana, semuenzaniso:

• Simba reChiratidzo %
• Simba reChiratidzo mu dB
• Hunhu hweChiratidzo
• SNR
• Chikamu Chechiratidzo Chakagamuchirwa

Ma parameter aya ane hukama, asihazvifanirwe kuenzaniswa zvakananga pakati pevagadziri vakasiyana kana mamodheru.

Pamuchina wekuyeresa mvura, bhuku remugadziri pamwe netsananguro yemukati memudziyo zvinofanira kushandiswa senzira yekutarisa.

7. Simba reChiratidzo vs. SNR

Kuti unzwisise zviri nani, zvakakoshawo kusiyanisaSimba reChiratidzokubvaSNR (Chiyero cheSignal-to-Noise).

Simba reChiratidzoinonyanya kutsanangura:

Simba rechiratidzo che ultrasound chakagamuchirwa rakasimba sei.

SNRinotsanangura:

Kuti chiratidzo chinobatsira chakasimba sei kana tichienzanisa neruzha rwekumashure.

Semuenzaniso, flow meter inogona kugamuchira chiratidzo chakasimba, asi kana ruzha rwemagetsi kana rwemakanika rwakakwirawo, SNR inogona kunge ichiri isina kunaka.

Saka, kana chishandiso chikapa ma parameter akadai se:

Simba reChiratidzo + SNR + Hunhu hweChiratidzo

zvakanaka kuti zviongororwe pamwe chete.

8. Simba reSignali Ringashandiswa Sei pakugadzirisa matambudziko?

Nzira inoshanda yekugadzirisa matambudziko ndeyekutarisa zvese zviri zvivirinhanho uye kugadzikanayechiratidzo.

Chiratidzo chakagadzikana uye chakasimba

Izvi zvinowanzoratidza kuti:

• Matransducer akabatana zvakanaka
• Nzira yekunzwa inzwi inogamuchirwa
• Chiratidzo chekugamuchira chakasimba

Zvisinei, kururama kwekuyera kuchiri kuda kuongororwa zvakasiyana.

Chiratidzo chisina kusimba zvakanyanya

Tarisa zvinotevera:

1. Kuisa transducer
2. Kubatanidza musanganiswa
3. Mamiriro epamusoro pepombi
4. Ukobvu hwemadziro epombi
5. Kuvhara mapaipi
6. Mabhurumu emhepo
7. Kana pombi yakazara zvachose
8. Nzvimbo yetransducer
9. Sarudzo yemuchina wekushandura
10. Mapaipi nema parameter emvura akaiswa mu flow meter

Simba rechiratidzo rinodzikira kamwe kamwe

Nyatsoteerera:

• Mabhubhu emhepo anopinda mupombi
• Matransducer akasununguka
• Kubatanidza kwakashata
• Kuchinja kwemamiriro ekushanda
• Kuchinja kwakakosha mukupisa kwemvura
• Kudedera kwepombi

9. Simba reChiratidzo Chinonyanya Kuratidza Hutano hweAcoustic

Pakupedzisira,Simba rechiratidzo rinofanira kuonekwa sechiratidzo chekuongorora acoustic pane kuti rionekwe sechiratidzo chekururama kwakananga.

Zvinobatsira kupindura mubvunzo uyu:

"Chiratidzo che ultrasonic chiri kufamba nemupombi nemumvura here uye chiri kugamuchirwa nemazvo?"

Hazvipinduri, zvoga, kuti:

"Kuyerwa kwekuyerera kwemvura kwakarurama here?"

Kuongorora kwakakodzera kunofanira kufunga nezvezvinhu zvakawanda:

Simba reSignali + SNR/Hunhu hweSignali + Kuiswa kweTransducer + Mamiriro ePaipi + Mamiriro emvura + Ruzivo rwekuyerera + Kugadzirisa

Saka, mumabasa ekugadzira mainjiniya,Simba remasaini rinonyanya kubatsira pakusimbisa kuiswa, kugadzirisa matambudziko, uye kutarisa mamiriro enzwi ehurongwa hwekuyera—kwete senzira yega yekuratidza kururama kwekuyera.
