Kuki icyuma gipima ikirere gikoresha ikoranabuhanga rya Ultrasonic kigera ku rugero rwo hejuru rw'amanota?

Ku gipimo cy'amazi gikoreshwa mu gupima ikirere hakoreshejwe ikoranabuhanga,guhindagurika kw'ingingo za zeruyerekeza ku gihe aho icyuma gipima amazi kigaragaza umuvuduko muto w'amazi nubwo umuyoboro wagombaga kuba uri ku rugero rwa zeru.

Iki kintu ni ingenzi cyane kuriibipimo by'amazi ya ultrasound mu gihe cyo kunyuramo, kuko igipimo cy'amazi kibarwa uhereye ku itandukaniro riri hagati y'igihe cyo hejuru n'igihe cyo hasi cyo mu mazi. Mu gihe ntarengwa cyo kugenda neza, igihe cyo kugenda kigomba kuba kingana. Ariko, mu by'ukuri, itandukaniro rito rishobora kubaho bitewe n'imiterere y'aho amazi ashyirwa, imiterere y'amazi, gutigita kw'imiyoboro, ubwiza bw'ibimenyetso, n'amakosa yo gupima ikoranabuhanga.

1. Umuyoboro ushobora kuba utari ku rugero rwa Zero

Ikintu cya mbere cyo kugenzura ni ukumenya niba umuyoboro utemba nta ruhushya koko.

Umuvuduko muto ushobora kubaho bitewe na:

• Gusohoka kwa valve
• Itandukaniro ry'umuvuduko hagati y'ibice bibiri by'iyi sisitemu
• Izenguruka ry’ikirere mu buryo busanzwe
• Gukoresha ubushyuhe mu buryo bw'amazi ashyushye
• Urugendo rwo kwinjira mu nzira
• Inzira y'amaraso iterwa na pompe
• Isigara ry'amazi nyuma y'uko pompe ihagaze

Urugero, igipimo cy'amazi gishobora kugaragaza0.05 m/snyuma yuko pompe izimye. Ibi ntibivuze ko icyuma gipima amazi gifite ikibazo cya zeru-point. Hashobora kuba hari amazi make agenda mu muyoboro.

Bityo rero,Kugenzura imiyoboro ya zeru bigomba gukorwa gusa nyuma yo kwemeza ko umuyoboro uhagaze neza kandi wuzuyemo amazi.

2. Gushyiramo Transducer idakwiye

Ku bipimo by'amazi bipima amashanyarazi hakoreshejwe ikoranabuhanga (clamp-on ultrasonic flow menter), gushyiraho transducer bigira ingaruka zikomeye ku buryo ibipimo bihamye.

Ibibazo bishobora kubaho iyo:

• Imashini zihindura imiterere y'umubiri ntiziri ku murongo ukwiye.
• Intera iri hagati ya transducer ntabwo ari yo.
• Transducers zombi zifite imiterere itandukanye yo guhuza.
• Transducers zishyirwa ku nguni itari yo.
• Ubuso bw'aho bashyiramo bwanduye cyangwa bungana.
• Uburyo bwo gushyiraho bwatoranijwe ntibuhuye n'imiterere nyayo y'imiyoboro.

Ibi bibazo bishobora gutuma ibimenyetso by'amajwi byo hejuru n'ibyo hasi byitwara mu buryo butandukanye.

Kubera iyo mpamvu, icyuma gipima ubwiyongere bw'amazi gishobora kubona itandukaniro rito rigaragara mu gihe cyo kunyuramo ndetse n'igihe nta bwiyongere bw'amazi buhari.

3. Kunyeganyega k'umuyoboro bishobora gutera ikimenyetso cy'amazi agaragara

Kunyeganyega kwa mekanike ni indi mpamvu ishobora gutuma hatabaho kudahuzagurika.

Iyo icyuma gipima amazi gishyizwe hafi ya:

• Pompe
• Kompreseri
• Moteri nini
• Valves
• Ibindi bikoresho binyeganyega

gutigita bishobora kugira ingaruka ku guhuza hagati ya transducer n'urukuta rw'umuyoboro.

Ishobora kandi kwinjiza urusaku mu kimenyetso cya ultrasound cyakiriwe.

Ikimenyetso gisanzwe ni uko igipimo cy'amazi kigaragara kitaguma kuri zeru ihamye, ahubwo gihinduka hafi ya zeru, urugero:

0 → 0.03 → -0.02 → 0.05 → 0 m/s

Muri iki gihe, guhindura amanota ya zeru inshuro nyinshi bishobora kudakemura ikibazo cy’ibanze. Ahantu ho gushyiraho ibikoresho hagomba kubanza gusuzumwa.

4. Udupira tw'umwuka dushobora kugira ingaruka ku kimenyetso cya Ultrasonic

Udupira tw'umwuka ni imwe mu mpamvu zikunze gutera ibipimo bidahindagurika bya ultrasound.

Kubera ko imiterere y'ijwi rya gaze n'amazi itandukanye cyane, utubumbe dushobora gukwirakwiza no kugabanya ikimenyetso cya ultrasound mu gihe kinyura mu muyoboro.

Ibi bishobora gutuma:

• Ingufu z'ikimenyetso zagabanutse
• Ubwiza bw'ikimenyetso budahamye
• Kumenya igihe cyo kunyura mu nzira bitari byo
• Isesengura ry'urujya n'uruza rw'amazi mu gihe runaka
• Impinduka mu gupima amanota ya zeru

Niyo mpamvu umuyoboro wagombye kubayuzuyemo amazi, kandi transducers ntizigomba gushyirwa ahantu umwuka ukunda kwirunda.

5. Impinduka mu bushyuhe bw'amazi

Impinduka z'ubushyuhe zishobora no kugira ingaruka ku kudahinduka kw'amanota ya zeru.

Impinduka mu bushyuhe zihindura amazi:

• Umuvuduko w'ijwi
• Ubucucike
• Ubucucike

Muri icyo gihe, kwaguka k'ubushyuhe bishobora guhindura gato ingano y'umuyoboro n'inzira y'amajwi.

Nubwo uburyo bwo gutwara abantu mu gihe cy’urugendo bushingiye ahanini ku itandukaniro riri hagati y’igihe cy’urugendo rwo hejuru n’urwo hasi aho kuba umuvuduko w’amajwi gusa, impinduka zikomeye mu mikorere zishobora kugira ingaruka ku bwiza bw’ibimenyetso no ku kudahinduka kw’ibipimo.

Ibi ni ingenzi cyane cyane mu ikoreshwa ry’amazi ashyushye, amazi akonje, n’ibindi bintu bivamo ubushyuhe bwinshi.

6. Amakosa mu gutunganya ibimenyetso by'ikoranabuhanga n'ibimenyetso

Itandukaniro ry'igihe cyo kunyuramo ripimwe n'icyuma gipima ikirere gishobora kuba gito cyane, cyane cyane iyo umuvuduko w'amazi uri hasi.

Bityo rero, uburyo bwo gupima bugomba kugaragaza neza itandukaniro rito cyane mu gihe cyo gutwara ibyuma hakoreshejwe ikoranabuhanga.

Ibintu nka:

• Urusaku rw'ikoranabuhanga
• Ihamye y'isaha
• Gutahura ibimenyetso
• Ingaruka z'ubushyuhe ku bice by'ikoranabuhanga
• Algorithm zo gutunganya ibimenyetso
• Guhagarara kw'urukiramende rw'itumanaho

bishobora kugira ingaruka ku gipimo hafi y'aho amazi anyura.

Iyi ni imwe mu mpamvu ituma imikorere y'icyuma gipima amashanyarazi kiva kuri ultrasound idaterwa gusa na transducers zacyo, ahubwo iterwa n'ubwiza bwacyo.uburyo bwo gutunganya ibimenyetso no gupima igihe.

7. Impamvu Zero Calibration Atari yo buri gihe iba igisubizo gikwiye

Ikosa rikunze kubaho ni uguhita ukora calibration ya zeru igihe cyose icyuma gipima amazi kigaragaza amazi make ku gihe nta mazi aturuka.

Tuvuge ko amazi nyayo ari zeru, ariko icyuma gipima amazi kigaragaza buri gihe:

+0.08 m/s

Gupima zeru bishobora kugabanya neza agaciro kagaragajwe kugeza kuri zeru.

Ariko, niba impamvu nyayo ari utubumbe tw'umwuka, guhindagura, kudahuza neza kwa transducer, cyangwa kuva kw'ingufu mu mashini, ikosa rishobora kuba ritahoraho.

Urugero, isomwa rishobora guhinduka riva kuri:

+0.08 m/s → -0.03 m/s → +0.05 m/s

Muri iki gihe, gupima nta bushobozi bishobora gukuraho ikibazo cy’ibanze.

Uburyo bwiza bwo gukemura ibibazo ni ubu:

Emeza ko nta muyoboro utemba → Reba uko umuyoboro umeze → Reba uko transducer ishyirwa → Reba imbaraga z'ikimenyetso → Reba ko nta byuma bihumeka n'ihindagurika ry'umwuka → Reba uko ubushyuhe bumeze → Kora igenzura rya zero niba ari ngombwa.

8. Uburyo bwo gutandukanya ubwoko butandukanye bw'ibibazo bya zeru-point

Kunyerera kwa zero-point muri ultrasound flow meter nintabwo byanze bikunze biterwa n'ingingo ya zeru y'ikoranabuhanga ubwayo.

Mu bikorwa byinshi byo mu isi nyayo, ikintu gisa nkaho ari ukugenda kwa zeru mu by'ukuri ni ingaruka zo kuvangaamazi make nyayo, gushyiraho transducer, gutigita kw'imiyoboro, utubumbe tw'umwuka, impinduka z'ubushyuhe, ubwiza bw'ikimenyetso, no kudahindagurika kw'ibipimo by'ikoranabuhanga.

Bityo rero, uburyo bwiza si uguhindura inota rya zeru gusa. Injeniyeri agomba kubanza kumenya niba ikibazo gikomoka kuriumuyoboro, amazi, gushyiraho, ikimenyetso cy'amajwi, cyangwa ibikoresho by'ikoranabuhanga.

Ku bipimo by'amazi ya ultrasonic bipima amashanyarazi, rebaImbaraga z'ikimenyetso, kudahungabana kw'ikimenyetso, intera iri hagati ya transducer, imiterere y'imiyoboro, n'ubwiza bw'aho gihurirani ingenzi cyane mbere yo gukora igenzura rya zero.
