Kodi chifukwa chiyani mita yoyezera kuchuluka kwa madzi yomwe imapangidwa ndi ma ultrasound ndi yolakwika?

1. Mphamvu ya gawo la chitoliro cholunjika cha pamwamba ndi pansi pa chitoliro pa kulondola kwa muyeso wa ultrasound flowmeter. Calibration coefficient K imagwira ntchito ya nambala ya Reynolds. Pamene liwiro la kuyenda silikugwirizana kuchokera ku laminar flow kupita ku turbulent flow, calibration coefficient K idzasintha kwambiri, zomwe zimapangitsa kuti kulondola kwa muyeso kuchepe. Malinga ndi zofunikira pakugwiritsa ntchito, ultrasonic flow meter transducer iyenera kuyikidwa mu gawo la chitoliro cholunjika cha 10D, gawo la chitoliro cholunjika cha pansi pa malo a 5D, kuti pakhale mapampu, ma valve ndi zida zina pamwamba pa chitoliro cholunjika, zofunikira za "mtunda kuchokera ku turbulence, kugwedezeka, gwero la kutentha, gwero la phokoso ndi gwero la ray momwe zingathere". Ngati pali mapampu, ma valve ndi zida zina pamwamba pa malo oyika a ultrasonic flow meter transducer, gawo la chitoliro cholunjika liyenera kukhala loposa 30D. Chifukwa chake, kutalika kwa gawo la chitoliro cholunjika ndicho chinthu chachikulu chotsimikizira kulondola kwa muyeso.

2. Mphamvu ya zida zoyezera mapaipi pa kulondola kwa muyeso wa ultrasound flowmeter. Kulondola kwa muyeso wa payipi kumagwirizana kwambiri ndi kulondola kwa muyeso. Ngati muyeso wa zinthu ndi kukula kwa payipi sizikugwirizana ndi zenizeni, izi zingayambitse cholakwika pakati pa malo ozungulira payipi ndi malo enieni ozungulira payipi, zomwe zimapangitsa kuti pakhale zotsatira zomaliza zosalondola. Kuphatikiza apo, mtunda wotuluka pakati pa transducer ya ultrasound flow meter ndi zotsatira za kuwerengera kwathunthu kwa magawo osiyanasiyana monga madzi (liwiro la phokoso, kukhuthala kwamphamvu), payipi (zinthu ndi kukula), ndi njira yoyikira transducer, ndi zina zotero, ndipo mtunda woyikira transducer umasiyana, zomwe zingayambitsenso zolakwika zazikulu zoyezera. Pakati pawo, muyeso ndi mtunda woyikira wa warp wamkati wa payipi zimakhudza kwambiri kulondola kwa muyeso. Malinga ndi deta yoyenera, ngati cholakwika chamkati cha payipi ndi ±1%, chimayambitsa cholakwika cha ±3% cha flow; Ngati cholakwika cha mtunda woyikira ndi ±1mm, cholakwika cha flow chidzakhala mkati mwa ±1%. Zikuoneka kuti pokhapokha ngati payikidwa bwino magawo a mapaipi, ultrasound flowmeter ikhoza kuyikidwa molondola ndipo mphamvu ya magawo a mapaipi pa kulondola kwa muyeso ingachepe.

3, mphamvu ya malo oyika transducer ya ultrasound flow meter pa kulondola kwa muyeso. Pali njira ziwiri zoyikira transducer: mtundu wowunikira ndi mtundu wolunjika. Ngati kugwiritsa ntchito liwiro la phokoso loyikira mwachindunji kuli kochepa, mphamvu ya chizindikiro ikhoza kuwonjezeka.

4. Mphamvu ya cholumikizira pa kulondola kwa muyeso. Kuti zitsimikizire kuti chikugwirizana bwino ndi payipi, poyika cholumikizira, gawo la cholumikizira liyenera kuphimbidwa mofanana pamwamba pa payipi, ndipo makulidwe onse ndi (2mm - 3mm). Ma thovu ndi tinthu tating'onoting'ono mu cholumikiziracho zimachotsedwa kuti pamwamba pa cholumikiziracho pakhale cholumikizidwa bwino ndi khoma la chubu. Ma flowmeter oyezera madzi ozungulira nthawi zambiri amayikidwa mu Wells, ndipo chilengedwe chimakhala chonyowa ndipo nthawi zina chimasefukira. Ngati cholumikizira chapadera chikugwiritsidwa ntchito, chidzalephera pakapita nthawi yochepa, zomwe zimakhudza kulondola kwa muyeso. Chifukwa chake, cholumikizira chapadera chosalowa madzi chiyenera kusankhidwa, ndipo cholumikiziracho chiyenera kugwiritsidwa ntchito mkati mwa nthawi yoyenera, nthawi zambiri miyezi 18. Kuti zitsimikizire kulondola kwa muyeso, cholumikiziracho chiyenera kubwezeretsedwanso miyezi 18 iliyonse ndipo cholumikiziracho chiyenera kusinthidwa.
