Kuyerekeza Mamita Osiyanasiyana a Kupanikizika ndi Mamita Oyendera a Ultrasonic

Ma flow meters ndi zida zofunika kwambiri zomwe zimagwiritsidwa ntchito m'mafakitale osiyanasiyana poyesa kuchuluka kwa madzi ndi mpweya. Mitundu iwiri yodziwika bwino ya flow meters ndiMamita oyendera magetsi osiyanasiyana (DP)ndizoyezera kuyenda kwa ma ultrasonicMtundu uliwonse uli ndi ubwino wake ndipo umagwirizana ndi ntchito zosiyanasiyana. M'nkhaniyi, tiyerekeza mitundu iwiri iyi ya zoyezera madzi, kukambirana momwe zimagwirira ntchito, ubwino wake, ndi momwe zimagwiritsidwira ntchito bwino.

1. Kodi Ma Differential Pressure Flow Meters Amagwira Ntchito Bwanji?

A mita yoyendera kuthamanga kosiyanaimayesa kuchuluka kwa madzi mwa kupanga kutsika kwa mphamvu kudutsa malire oyendetsera madzi (monga mbale ya orifice, chubu cha venturi, kapena nozzle ya madzi). Mfundo ya mtundu uwu wa mita imachokera paMfundo ya Bernoulli, zomwe zimati pamene liwiro la madzi likuwonjezeka, kuthamanga kwake kumachepa.

Mfundo Yogwirira Ntchito:

• A choletsa(monga, mbale ya orifice) imayikidwa munjira yoyendera madzi, zomwe zimapangitsa kuti kuthamanga kwa madzi kuchepe.
• Chiyesocho chimayesa kusiyana kwa kuthamanga kwa magazi asanayambe komanso atatha kuletsa (kupanikizika kosiyana).
• Pogwiritsa ntchito ubale pakati pa kutsika kwa kupanikizika ndi kuchuluka kwa madzi, choyezera madzi chimawerengera kuchuluka kwa madzi pogwiritsa ntchito njira zamasamu kapena ma calibration curves.

Kupanikizika kosiyana kumagwirizana mwachindunji ndi liwiro la madzi, zomwe zimathandiza mita kuwerengera kuchuluka kwa madzi.

2. Kodi Ma Ultrasonic Flow Meters Amagwira Ntchito Bwanji?

An mita yoyendera ma ultrasonicimagwiritsa ntchito mafunde amawu (mafunde a ultrasonic) poyesa kuchuluka kwa madzi kapena mpweya. Pali mitundu iwiri ikuluikulu ya zoyezera kuyenda kwa ma ultrasound:nthawi yoyenderandiDopplerMa ultrasound mita oyendera nthawi yodutsa amagwiritsidwa ntchito kwambiri mu zakumwa zoyera komanso zofanana, pomwe ma Doppler mita amagwiritsidwa ntchito mu zakumwa zomwe zili ndi tinthu tating'onoting'ono kapena thovu lotayirira.

Mfundo Yogwirira Ntchito:

• Ma ultrasound mita oyendera nthawi yoyenderakutumiza ma pulse a ultrasound pamwamba ndi pansi pa madzi kudzera mu madzi. Poyerekeza nthawi yomwe ma pulse amatenga kuti ayende mbali zonse ziwiri, kuchuluka kwa kuyenda kwa madzi kumatsimikiziridwa kutengera kusiyana kwa nthawi komwe kumachitika chifukwa cha liwiro la kuyenda kwa madzi.
• Ma Doppler ultrasound mitantchito poyesa kusintha kwa mafunde a phokoso komwe kumawonetsa tinthu tating'onoting'ono kapena thovu mumadzimadzi. Kuthamanga kwa madzi kumatsimikiziridwa kutengera kukula kwa kusintha kwa mafunde kumeneku.

Ma flow meter a ultrasound safuna ziwalo zosuntha ndipo nthawi zambiri amaikidwa kunja kwa chitoliro, zomwe zimapangitsa kuti akhale abwino kwambiri poyesa flow flow osalowa m'thupi.

3. Ubwino wa Mamita Oyendera Magazi Osiyanasiyana

Ma differential pressure flow mita akhala akugwiritsidwa ntchito kwambiri kwa zaka zambiri ndipo amadaliridwa chifukwa chodalirika pa ntchito zosiyanasiyana. Zina mwa zabwino zazikulu ndi izi:

a. Ukadaulo Wokhazikika Bwino

• Ma differential pressure flow meter akhala akugwiritsidwa ntchito kwa zaka zambiri ndipo ndi ukadaulo wodziwika bwino. Amagwiritsidwa ntchito kwambiri m'mafakitale monga mafuta ndi gasi, kukonza mankhwala, komanso kuyeretsa madzi.

b. Kulondola Kwambiri pa Zakumwa ndi Mpweya

• Amapereka miyeso yodalirika komanso yolondola ya kayendedwe ka madzi ndi mpweya wosiyanasiyana, makamaka pamene kayendedwe ka madzi ndi mpweya ndi kokhazikika komanso kodziwikiratu.

c. Yolimba komanso Yotsika Mtengo

• Mamita amenewa nthawi zambiri amakhala olimba ndipo amatha kupirira kupsinjika kwakukulu ndi kutentha, zomwe zimapangitsa kuti akhale abwino kwambiri m'malo ovuta kwambiri a mafakitale.
• Kawirikawiri zimakhala zotsika mtengo kuposa mitundu ina ya zoyezera madzi.

d. Yoyenera Madzi Okhuthala Kwambiri

• Ma flow meter osiyanitsa mphamvu amagwira ntchito bwino ndi zakumwa zokhala ndi kukhuthala kwakukulu, monga mafuta kapena slurry, komwe ma flow meter ena angavutike.

4. Ubwino wa Ma Ultrasonic Flow Meters

Ma flow meters a Ultrasonic atchuka kwambiri m'zaka zaposachedwa chifukwa cha ukadaulo wawo wapamwamba komanso njira zoyezera zosawononga chilengedwe. Nazi zabwino zina zazikulu:

a. Kuyeza Kosalowerera

• Ma ultrasound flow meters amatha kuyikidwa kunja kwa chitolirocho, popanda kukhudzana ndi madzi, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito komwe kumafunika kupewa kuipitsidwa, kapena madziwo ndi ovuta kuwapeza.

b. Palibe Zigawo Zosuntha

• Popeza ma ultrasound mita alibe ziwalo zosuntha, ali ndi zofunikira zochepa zosamalira poyerekeza ndi ma flow mita ena monga ma differential pressure mita, omwe nthawi zambiri amadalira zinthu zosuntha (monga ma orifice plates).

c. Yoyenera Zakumwa Zoyera ndi Zosayera

• Ma ultrasound flow mita okwana nthawi yoyenderandi oyenera kwambiri madzi oyera komanso ofanana monga madzi, mankhwala, ndi mafuta.Ma Doppler ultrasound mitaingagwiritsidwe ntchito pa zakumwa zomwe zili ndi zinthu zolimba zomwe zimapachikidwa kapena thovu la mpweya, monga madzi otayira kapena matope.

d. Kulondola Kwambiri

• Ma ultrasound flow meters amapereka kulondola kwakukulu ndipo ndi othandiza kwambiri poyesa kuchuluka kwa madzi otsika. Amathanso kuzindikira kusintha kochepa kwambiri kwa madzi, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito molondola.

e. Palibe Kutaya kwa Kupanikizika

• Mosiyana ndi zoyezera kuthamanga kwa magazi zosiyana, zomwe zimayambitsa kutsika kwa kuthamanga kwa magazi chifukwa cha kuchepetsedwa kwa njira yoyendera madzi, zoyezera kuthamanga kwa magazi zomwe zimagwiritsidwa ntchito popanga ma ultrasound sizimalepheretsa kuyenda kwa magazi ndipo sizimakhudza kuthamanga kwa madzi.

5. Kuyerekeza: Nthawi Yogwiritsira Ntchito Chiyeso Chilichonse Choyendera

Ma Differential Pressure Flow Meters ndi Abwino Kwambiri Ngati:

• Muyenera kuyeza kayendedwe ka madzi m'makina omwe ali ndi kuthamanga kwambiri kapena kutentha kwambiri.
• Madzi nthawi zambiri amakhala oyera kapena ofanana, ndipo kuchuluka kwa madzi m'thupi kumakhala kokhazikika.
• Mukulimbana ndi zakumwa kapena mpweya wokhuthala kwambiri, komwe mitundu ina ya mita singagwire ntchito bwino.
• Mukufuna njira yolimba komanso yotsika mtengo yogwiritsira ntchito mafakitale.

Ma Ultrasonic Flow Meters Ndi Abwino Kwambiri Ngati:

• Mukufunika kuyeza kosawononga madzi popanda kusokoneza kutuluka kwa madzi kapena kukhudza madziwo.
• Mukuyeza madzi kapena mpweya woyera, kapena mukugwiritsa ntchito Doppler ultrasonic flow meter kuti muyeze madzi ndi tinthu tomwe timapachikidwa kapena thovu.
• Mukufunika kuyeza kuyenda kwa madzi molondola kwambiri, makamaka pa ntchito zochepa.
• Mukufuna mita yokhala ndi zosowa zochepa zosamalira komanso yopanda kutsika kwa mphamvu.

6. Mapeto

Zonse ziwirimita yoyendera kuthamanga kosiyanandizoyezera kuyenda kwa ma ultrasonicndi zida zothandiza kwambiri poyezera kayendedwe ka madzi, koma ndizoyenera kwambiri pa ntchito zosiyanasiyana.

• Mamita oyendera kuthamanga kosiyanandi chisankho chabwino kwambiri pamakina amphamvu kwambiri, madzi amphamvu kwambiri, komanso malo achikhalidwe a mafakitale komwe kugwiritsa ntchito bwino ndalama komanso kudalirika ndikofunikira kwambiri.
• Ma ultrasonic flow mitaamapereka ubwino woyezera mosawononga chilengedwe, kulondola kwambiri, komanso kusakonza pang'ono, zomwe zimapangitsa kuti zikhale zabwino kwambiri pamadzi oyera, pakakhala madzi ochepa, komanso pakugwiritsa ntchito komwe kutayika kwa mphamvu kuyenera kupewedwa.

Kumvetsetsa kusiyana ndi ubwino wa zoyezera madzi ziwirizi kudzakuthandizani kusankha njira yabwino kwambiri yoyezera madzi yomwe mukufuna.
