Paunenge uchishandisa precessing vortex kuyerera mita kuyera nemazvo kuyerera kwese, zvinotevera nyaya dzinofanirwa kutariswa:
1. Iyo pombi inoyerera inopikisa inofanira kunge iri 2×104～7×106. Kana ikadarika iyi chiyero, index ye flowmeter, kureva kuti, nhamba yeStroha haisi parameter, uye kururamisa kunoderedza.
2. Kuyerera kwepakati kunofanira kunge kuri mukati mehutano hunodiwa, nokuti precession vortex flow meter inoyera kuyerera kwese kunoenderana nehuwandu. Naizvozvo, kuyerera kwepakati kunofanirwa kuve kwakaganhurirwa, uye masvikiro akasiyana ane akasiyana ekuyerera.
(1) Kana zvepakati zviri mhute, max velocity inofanira kudzika kudarika 60 m/s
(2) Kana yepakati iri chiutsi, inofanira kunge yakaderera kupfuura 70 m/s
(3) Iyo yakaderera-muganho wekuyerera mwero inoverengerwa kubva kune yakaenzana curve dhizaini kana formula yekuverenga yeinjini yezviridzwa zvichibva pane viscosity uye hukama density.
(4) Pamusoro pezvo, kumanikidza kwekushanda uye tembiricha yepakati inofanira kunge iri mukati meiyo inodiwa.
Maitiro eiyo precession vortex kuyerera mita.
1. Zvakanakira zvikuru
(1) Indekisi yekuenzanisa yemamita haizokuvadzwa nekumanikidzwa kwemvura yekushanda, tembiricha, hukama hwehukama, viscosity uye shanduko yekuumbwa, uye hapana chikonzero chekugadzirisa zvakare pakubvisa uye kutsiva zvikamu zvekuongorora;
(2) Chiyereso chechiyero chakakura, mvura inosvika 1:15, uye mhute inosvika 1:30;
(3) Iyo pombi yakatarwa inenge isingagumi, 25-2700 Mm;
(4) Kukuvadzwa kwebasa kudiki kwazvo;
(5) Pakarepo buritsa chiratidzo chemagetsi mutsara chine chekuita nekuyerera kwese, nehupamhi hwepamusoro, inosvika ± 1%;
(6) Kuiswa kuri nyore, mari yekuchengetedza idiki, uye zvikanganiso zvinowanzoitika zvishoma.
2. Kukanganisa kukuru
(1) The variable flow rate uye pulsating chinwiwa kuyerera kuchaisa mungozi kuyerwa kwechokwadi. Pane mirau yechikamu chekubatanidza kumusoro, yepakati uye yakaderera inosvika pane chiridzwa (matatu d kumusoro uye pasi, 1D pakati uye pasi). Kana zvichidikanwa, iyo inogadzirisa inofanira kuchinjwa kumativi ekumusoro uye pasi pemvura;
(2) Kana zvikamu zvekuongorora zvakasviba, kuyerwa kwechiyero kuchakanganiswa. Zvose zvinoyerera zvikamu uye maburi ekuongorora anofanirwa kucheneswa nemotokari peturu, peturu, ethanol, nezvimwewo nenguva.
3. Kuiswa kwe precession vortex flowmeter
1. Kana iyo flowmeter yakaiswa, inorambidzwa kuita arc welding pakarepo paflange yekutengeserana kwayo uye kutengesa kunze kwenyika kudzivirira kupisa mukati meiyo flowmeter.
2. Edza kuchenesa pombi ichangobva kuiswa kana kugadziriswa, uye isa flowmeter mushure mekubvisa tsvina mupombi.
3. The flowmeter inofanira kuiswa panzvimbo inokodzera kugadzirisa, pasina simba remasimba emagetsi, uye pasina damping vibration yakajeka uye inopenya inopisa ngozi;
4. The flowmeter haikodzeri nzvimbo iyo kuyerera kwese kunowanzo vhiringwa uye kune pachena pulsating chinwiwa chinoyerera kana kushanda kumanikidza pulsating zvinwiwa;
5. Kana iyo flowmeter ichiiswa kunze, panofanira kunge paine chivharo pamucheto wepamusoro kudzivirira kupindira kwemvura uye kubuda kwezuva kubva pakukuvadza hupenyu hwekuyerera;
6. Iyo inoyerera inogona kuiswa pane chero kona yekuona, uye kubuda kwemvura kunofanira kuenderana neinoyerera yakanyorwa pane flowmeter;
7. Panzvimbo yekuvaka pombi, kufunga kunofanira kupiwa kuisa zvigadzirwa kana mabhero esimbi kudzivirira kudhonza kwakanyanya kana kuputika kweiyo flowmeter;
8. Iyo inoyerera inofanirwa kuiswa coaxially neinobuda pombi, uye kudzivirira chisimbiso chidimbu uye isina munyu bhotela kuti isapinda mukati memadziro epaipi;
9. Paunenge uchishandisa kunze kwekushandura simba rekushandisa, iyo flowmeter inofanira kuva yakavimbika ivhu. Waya yepasi haigone kushandiswa neiyo isina kusimba system software. Panguva yekuisa pombi kana kugadzirisa, waya yekumisa yearc welding system software haigone kuputirwa neiyo flowmeter simbi bar. .
