Mukamagwiritsa ntchito mita yoyambira ya vortex kuti muyeze bwino kuthamanga konse, zotsatirazi ziyenera kuganiziridwa:
1. Kukana kwa payipi kumayenera kukhala 2 × 104 ~ 7 × 106. Ngati ipitilira izi, index ya flowmeter, ndiye kuti, nambala ya Stroha si chizindikiro, ndipo kulondola kumachepetsa.
2. Kuthamanga kwa sing'anga kuyenera kukhala mkati mwazomwe zimafunikira, chifukwa precession vortex flow mita imayesa kuthamanga kwathunthu kutengera ma frequency. Choncho, kuthamanga kwa sing'anga kuyenera kukhala kochepa, ndipo ma mediums osiyana amakhala ndi maulendo osiyanasiyana.
(1) Pamene sing'anga ndi nthunzi, liwiro lalikulu liyenera kukhala lotsika kuposa 60 m/s
(2) Pamene sing'anga ili nthunzi, ikhale yocheperapo 70 m/s
(3) Kuthamanga kwa malire otsika kumawerengedwera kuchokera pazithunzi zokhotakhota kapena mawerengedwe a chilinganizo cha gulu lachida kutengera kukhuthala ndi kachulukidwe wachibale.
(4) Kuphatikiza apo, kuthamanga kwa ntchito ndi kutentha kwa sing'anga ziyenera kukhala mkati mwazofunikira.
Makhalidwe a precession vortex flow mita.
1. Ubwino waukulu
(1) The calibration index wa mita sichidzavulazidwa ndi kuthamanga kwamadzimadzi, kutentha, kachulukidwe kachibale, kukhuthala kwa ma viscosity ndi kusintha kwapangidwe, ndipo palibe chifukwa chowonetseranso pamene mukuchotsa ndikusintha zigawo zoyendera;
(2) Chiyerekezo choyezera ndi chachikulu, madziwo amafika pa 1:15, ndipo nthunzi imafika pa 1:30;
(3) Kufotokozera kwa mapaipi ndi pafupifupi zopanda malire, 25-2700 Mm;
(4) Kuwonongeka kwa ntchito ndi kochepa kwambiri;
(5) Nthawi yomweyo tulutsani chizindikiro chamagetsi chogwirizana ndi kutuluka kwathunthu, molondola kwambiri, kufika ± 1%;
(6) Kuyikako ndikosavuta, ndalama zosamalira ndizochepa, ndipo zolakwika wamba ndizochepa kwambiri.
2. Zolakwika zazikulu
(1) Mayendedwe osinthasintha komanso kutulutsa kwachakumwa kumayika pachiwopsezo kulondola kwake. Pali malamulo okhudzana ndi gawo lolumikizana pamtunda wapamwamba, wapakati ndi wapansi wa gulu la chida (zitatu d kumtunda ndi kumtunda, 1D pakati ndi pansi). Ngati ndi kotheka, chowongoleracho chiyenera kusinthidwa kumbali yakumtunda ndi pansi;
(2) Pamene zigawo zoyendera zili zodetsedwa, kulondola kwa kuyeza kudzasokonezedwa. Magawo onse otaya ndi mabowo oyendera ayenera kutsukidwa ndi mafuta agalimoto, mafuta, ethanol, etc.
3. Kuyika kwa precession vortex flowmeter
1. Pamene flowmeter imayikidwa, ndiyoletsedwa kuchita kuwotcherera kwa arc nthawi yomweyo pa flange ya malonda ake otumizira ndi kutumiza kunja kuti asawotche mbali zamkati za flowmeter.
2. Yesani kuyeretsa payipi yomwe yangoikidwa kumene kapena yokonzedwa, ndikuyika flowmeter mutachotsa dothi mupaipi.
3. Flowmeter iyenera kukhazikitsidwa pamalo omwe ndi abwino kukonzanso, popanda mphamvu ya maginito amphamvu, komanso popanda kugwedezeka kwachidziŵikire ndi kuopsa kwa kutentha;
4. The flowmeter si oyenera malo otaya okwana nthawi zambiri kusokonezedwa ndipo pali zoonekeratu pulsating chakumwa umayenda kapena ntchito kuthamanga pulsating zakumwa;
5. Pamene flowmeter imayikidwa panja, payenera kukhala chivundikiro pamwamba pake kuti ateteze kulowetsedwa kwa mvula ndi kutuluka kwa dzuwa kuti zisawononge moyo wa flowmeter;
6. Flowmeter ikhoza kukhazikitsidwa pamawonedwe aliwonse, ndipo kutuluka kwamadzimadzi kuyenera kugwirizana ndi kutuluka komwe kumatchulidwa pa flowmeter;
7. Pamalo omanga mapaipi, kulingalira kuyenera kuganiziridwa pakuyika zinthu kapena zitsulo zachitsulo kuti zisakoke kwambiri kapena kuphulika kwa flowmeter;
8. Flowmeter iyenera kuyikidwa coaxially ndi kutulutsa kwa payipi, ndikuletsa chidutswa chosindikizira ndi batala wopanda mchere kulowa mkati mwa khoma la payipi;
9. Pogwiritsa ntchito magetsi osinthira kunja, flowmeter iyenera kukhala ndi chipangizo chodalirika chokhazikika. Waya wapansi sungagwiritsidwe ntchito ndi pulogalamu yofooka yamakono. Pakuyika kapena kukonza mapaipi, waya woyambira wa pulogalamu yowotcherera ya arc sungathe kupindika ndi chitsulo cha flowmeter. .
