Kodi makulitsidwe a chitoliro amakhudza ma ultrasonic flowmeters?

1. Ntchito mfundo ya akupanga flowmeter

Akupanga flowmeter ndi ambiri ntchito mafakitale otaya muyeso zida, ntchito akupanga masensa kuyeza liwiro kusiyana mu madzi kuwerengera otaya.Mfundo ndi losavuta: pamene akupanga yoweyula propagates mu madzi, ngati madzimadzi umayenda, wavelength wa phokoso yoweyula adzakhala wamfupi mu malangizo otaya ndi yaitali mosiyana.Poyesa kusinthaku, kuthamanga kwa madzi kungathe kutsimikiziridwa, ndipo kuthamanga kwa madzi kungathe kuwerengedwa kuchokera kumtunda wothamanga ndi gawo lozungulira la chitoliro.

2. Chitoliro chokweza

Komabe, mu zothandiza ntchito, ntchito ya akupanga flowmeters angakhudzidwe ndi makulitsidwe.Sikelo ndi dothi losanjikiza lomwe limapanga mkati mwa chitoliro ndipo limatha chifukwa cha madzi olimba, tinthu tating'ono tolimba, kapena zonyansa zina.Madzi akamadutsa mutoliro wa scaled, sediment imasokoneza kufalikira kwa mafunde a phokoso, zomwe zimapangitsa kuchepa kwa kulondola kwa zotsatira za kuyeza.

Kukhalapo kwa makulitsidwe kungayambitse mavuto angapo.Choyamba, kukula kosanjikiza kumalepheretsa sensa ya akupanga kuti ifike kumadzimadzi, kufooketsa yankho la chizindikiro pakati pa kafukufuku ndi madzimadzi.Kachiwiri, lonse wosanjikiza ali ena lamayimbidwe impedance, zimene zingakhudze kafalitsidwe liwiro ndi mphamvu imfa ya akupanga yoweyula, chifukwa muyeso zolakwa.Komanso, sikelo wosanjikiza akhoza kusintha otaya mkhalidwe wa madzimadzi, kuonjezera mlingo wa chipwirikiti madzimadzi, kuchititsa zotsatira zolakwika zambiri muyeso.

3. Njira zothetsera ndi zodzitetezera

Pofuna kuthana ndi vuto la makulitsidwe omwe amakhudzidwa ndi ma ultrasonic flowmeters, zotsatirazi zitha kuchitidwa:

Choyamba, chitolirocho chimatsukidwa nthawi zonse kuti chichotse makulitsidwe ndikusunga khoma lamkati la chitoliro kukhala losalala.Izi zitha kuchitika pogwiritsa ntchito nambala yoyenera ya zotsukira mankhwala kapena zida zoyeretsera.

Kachiwiri, kusankha ntchito akupanga flowmeter ndi odana makulitsidwe ntchito.Flowmeters oterowo nthawi zambiri amapangidwa ndi zovuta zokulitsa m'malingaliro, ndipo zida zapadera zimakutidwa pamwamba pa sensa kuti zichepetse kuthekera kwa makulitsidwe.

Pambuyo pake, kuyang'anira nthawi zonse ndi ntchito yokonza ikuchitika kuti akonze mavuto omwe angapangitse kuti makulitsidwe mu nthawi kuonetsetsa ntchito yachibadwa ya akupanga flowmeter.

Ngakhale zotsatira za makulitsidwe pa akupanga flowmeters sangathe kwathunthu inathetsedwa, kusokoneza makulitsidwe pa muyeso zotsatira akhoza kuchepetsedwa kudzera wololera njira zodzitetezera ndi kukonza.Kugwiritsa ntchito odana ndi makulitsidwe akupanga otaya mamita, ndi nthawi zonse kuyeretsa ndi kukonza, akhoza kuonetsetsa kulondola kwa otaya mita ndi kukhazikika kwa nthawi yaitali.
