Kuisa mapaipi chinhu chakakosha chekufunga nezvacho pakuisamita yekuyerera kwe ultrasonic inobatidzwaKunyangwe ma transducer akaiswa kunze kwepombi, chiratidzo che ultrasonic chinofanira kupfuura nepamadziro epombi uye, kazhinji, mukati memukati mepombi isati yasvika pamvura.

Nokudaro, rudzi uye ukobvu hwepombi inogona kuva nepesvedzero huru pasimba rechiratidzo, kutumira acoustic, nzvimbo ye transducer, uye kugadzikana kwekuyera.

1. Chiratidzo cheUltrasonic Chinofamba Sei Nepaipi Yakarukwa?

Kune ultrasound flow meter yakajairika inobatidzwa, chiratidzo che ultrasonic chinotevera nzira yakafanana neiyi:

Transducer → Wall yePombi → Lining yePombi → Mvura → Lining yePombi → Wall yePombi → Transducer

Kusiyana nechinhu chinopinzwa mvura, ma transducers haabatani zvakananga nemvura.

Chiratidzo che ultrasonic chinofanira kufamba nepakati pezvinhu zvakasiyana-siyana chisati chasvika mumvura. Chinhu chimwe nechimwe chine hunhu hwakasiyana hwe acoustic, saka chiratidzo chinogona kunzwa kuratidzwa, kudzorwa, uye kudzikira kwesimba panzvimbo dziri pakati pezvinhu.

Ndosaka pombi dzichifanira kutariswa panguva yekuisa ultrasonic flow meter.

2. Sei Chigadzirwa Chemukati Chichikosha?

Zvinhu zvakasiyana zve lining zvine zvakasiyanaacoustic impedance uye kumhanya kweruzha.

Zvinhu zvakajairika zvekubatanidza mapaipi zvinosanganisira:

• PTFE
• Rabha
• Rabha yakaoma
• Dura resimende
• Epoxy
• Purasitiki
• Zvimwe zvipfeko zvekudzivirira

Kana mafungu e ultrasound achifamba kubva pane chimwe chinhu kuenda kune chimwe, chikamu chesimba rayo chinogona kuratidzwa panzvimbo yacho.

Semuyenzaniso:

Madziro epombi → Mucheka → Mvura

Pachinhu chimwe nechimwe chinopindirana, musiyano wehunhu hweacoustic unogona kukanganisa kuti simba re ultrasonic rinopinda sei muchinhu chinotevera.

Kana kusawirirana kwemanzwi kuri kukuru, simba rakawanda rinogona kuratidzwa uye simba shoma rinogona kusvika kune transducer inogamuchira.

Izvi zvinogona kuguma ne:

Simba remasaini rakaderera uye kuyerwa kwemanzwi kwakaoma.

3. Sei Kukobvu Kwemupendero Kuchikosha?

Kukosha kwejira remukati kwakakoshawo.

Kamuri katete kanogona kunge kasina simba rakawanda, nepo kamuri katete kachigona kuwedzera zvakanyanya kureba kwenzira inonzwika kuburikidza nejira.

Sezvo chiratidzo che ultrasound chichifamba nepakati pejira, chikamu chesimba racho chinogona kudzikira.

Nokudaro, mamiriro ekuyera anokonzerwa ne:

Zvinhu zveLining + Lining Ukobvu + Acoustic Properties

Nekuda kwechikonzero ichi, mapaipi maviri ane dhayamita imwechete uye zvinhu zvakafanana zvekunze zvinogona kuita zvakasiyana kana machira avo emukati akasiyana.

Semuyenzaniso:

Pombi yesimbi yekabhoni isina jira

uye

Pombi yesimbi yekabhoni ine rabha gobvu

inogona kunge iine hunhu hwakasiyana zvakanyanya hwekutapurirana kwe ultrasonic.

4. Sei Rubha neMachira epurasitiki zvichigona kuva zvakaoma?

Zvimwe zvinhu zvemukati zvakapfava kana zvine ruzha rwakaderera zvinogona kuita kuti kuyerwa kwe clamp-on ultrasonic kuve kwakaoma.

Mienzaniso inosanganisira mimwe:

• Machira erabha
• Mapeteni ePTFE
• Mapeteni epurasitiki

Mafungu e ultrasonic anogona kunzwa kurerukirwa kana kuratidzwa zvakanyanya kana achipfuura nepakati pezvinhu izvi.

Izvi zvinogona kutungamira ku:

• Simba rechiratidzo rakaderedzwa
• Kuoma kwakawedzera pakuona zviratidzo
• Nzvimbo yakamanikana yenzvimbo yakakodzera ye transducer
• Kunzwisisa zvakanyanya mamiriro ekuisa

Izvi hazvirevi kuti mapaipi ane tambo haakwanise kuyerwa.

Asi, chiyereso chekuyerera kwemvura chinofanira kusarudzwa nemazvo uye kugadziriswa zvichienderana nemamiriro chaiwo epombi uye lining.

5. Kuisa mapaipi pamipendero kunokanganisa sei nzvimbo pakati pematransducers?

Pakuyera ma flow meter e clamp-on ultrasonic, nzvimbo ye transducer inowanzo verengerwa zvichibva pane zvakasiyana-siyana, zvinosanganisira:

• Dhayamita yepombi
• Ukobvu hwemadziro epombi
• Zvinhu zvepombi
• Zvinhu zvemukati
• Ukobvu hwerineni
• Rudzi rwemvura
• Tembiricha yemvura
• Kumhanya kweUltrasonic kuburikidza nezvinhu zvakasiyana

Saka, kana ruzivo rwemukati rwakaiswa mu flow meter rusina kururama, nzvimbo yakaverengerwa ye transducer inogonawo kunge isiriyo.

Semuenzaniso, kana pombi chaiyo iine rabha ye5 mm asi chishandiso chacho chakagadzirwa sepombi yesimbi isina mutsetse, nzira yeacoustic yakaverengerwa inogona kusaenderana nemazvo nechimiro chepombi chaiyo.

Izvi zvinogona kuita kuti kuwana zviratidzo kuve kwakaoma uye zvinogona kukanganisa mashandiro ekuyera.

6. Muchina wekuyeresa mvura unogona here kuva nechiratidzo chakasimba papombi ine tambo?

Ehe.

Pombi yakarukwa hairevi kuti chiratidzo che ultrasonic chichava chisina simba.

Simba rechiratidzo chaicho rinoenderana nemigumisiro yakabatana ye:

Zvinhu zvepaipi + Ukobvu hwemadziro + Lining + Lining + Liquid + Transducer + Kuisa

Kuiswa kwakagadzirwa zvakanaka papombi yakarukwa kunogona kupa chiratidzo che ultrasound chakasimba uye chakasimba.

Saka, kuvapo kwejira remukati hakufanirwe kuonekwa sechiratidzo chega chekuti kuyerwa kwe clamp-on ultrasound hakuna kukodzera.

7. Mabhubhu emhepo anogona sei kuita kuti dambudziko riwedzere kuipa?

Mapaipi ane tambo anogonawo kukonzera dambudziko: kuungana kwemhepo.

Kana pombi isina kuzadzwa zvizere, kana kuti kana paine mabubble emhepo mumvura, chiratidzo che ultrasonic chinogona kudzikira zvakanyanya kana kupararira.

Mamiriro akabatanidzwa e:

Mucheka wakakora + Mafuro emhepo + Kubatana kusina kunaka

zvinogona kuita kuti kutapurirana kwemasaini e ultrasonic kuve kwakaoma zvikuru.

Saka, nzvimbo yekuisa inofanira kusarudzwa zvakanaka pane imwechikamu chepombi chakazadzwa zvizere, kure nenzvimbo dzinogona kuungana mhepo.

8. Mainjiniya Anofanira Kuongorora Sei Pombi Yakarukwa?

Usati waisa clamp-on ultrasonic flow meter, zvinokurudzirwa kuunganidza ruzivo runotevera:

1. Dhayamita yekunze kwepombi
2. Ukobvu hwemadziro epombi
3. Zvinhu zvepombi
4. Zvinhu zvemukati
5. Ukobvu hwerineni
6. Rudzi rwemvura
7. Tembiricha yemvura
8. Kumhanya kwekuyerera kunotarisirwa
9. Mamiriro epombi
10. Kureba kwepombi yakatwasuka kunowanikwa

Ruzivo urwu runobvumira flow meter kuti ione magadzirirwo akakodzera e acoustic uye nzvimbo ye transducer.

Kune mapurogiramu akaoma, kuyedzwa kwechokwadi panzvimbo yacho kunogonawo kubatsira usati waisa.

9. Ndezvipi Zviratidzo Zvinozivikanwa zveDambudziko Rine Chekuita Nemachira?

Dambudziko re acoustic rine chekuita ne lining rinogona kuoneka seizvi:

• Simba rechiratidzo rakaderera
• Simba rechiratidzo risina kugadzikana
• Kuoma kuwana chiratidzo che ultrasound
• Kuverengwa kwemvura kusina kurongeka kana kuti kusina kugadzikana
• Kurasikirwa kwechiratidzo kakawanda
• Kunzwa kwakasimba kunzvimbo yetransducer

Zvisinei, zviratidzo izvi hazvirevi hazvo kuti jira racho ndiro chete rinokonzera.

Zviratidzo zvakafanana zvinogonawo kukonzerwa ne:

• Kubatana kusina kunaka kwetransducer
• Nzvimbo isiriyo ye transducer
• Ukobvu hwemadziro epombi hwakanyanya
• Mabhurumu emhepo
• Maparamita epombi asina kururama
• Kuora kwepombi pamusoro pemvura
• Kudedera kwepombi

Saka, kugadzirisa matambudziko kunofanira kufunga nezvenzira yese yeacoustic pane kutarisa pane lining chete.

Kuiswa kwepombi kunokanganisa kuyerwa kwekuyerera kwe clamp-on ultrasonic nekuti chiratidzo che ultrasonic chinofanira kupfuura nepakatimadziro epaipi nejira remukati usati wapinda mumvura.

Zvinhu zvemukati uye ukobvu zvinogona kukanganisa kufambisa kwenzwi, kuderedza masaini, kuratidzwa, uye nzvimbo inodiwa ye transducer.

Zvinhu zvikuru zvinogona kupfupikiswa seizvi:

Zvinhu zvepaipi + Ukobvu hwemadziro + Zvinhu zvepajira + Ukobvu hwepajira + Zvinhu zvine mvura → Kutumira kweacoustic → Hunhu hwechiratidzo → Kugadzikana kwekuyera

Saka, pakusarudza nekuisa bhandi remagetsi rinobata jira, jira repaipi rinofanira kugara richionekwa sechikamu chakakosha chenzira yekuyera acoustic.

Pombi yakarukwa hairevi hazvo kuti inodzivirira kuyerwa kwe ultrasound, asizvinhu zvemukati uye ukobvu zvinofanirwa kutariswa nemazvo panguva yekusarudza flow meter, kugadzirisa ma parameter, uye kuisa transducer.
