Mumamiriro api ezvinhu apo electromagnetic flowmeter isingakodzeri kushandiswa?

Mamita ekuyerera kwemagetsizvishandiso zvinoyera kuyerera kwemvura inoyerera zvichibva pamutemo we electromagnetic induction. Kazhinji hazvikodzeri kushandiswa mumamiriro ezvinhu anotevera:

1. Kuyera zvinwiwa zvisina kufambisa mvura: Pfungwa yekushanda kwema electromagnetic flow meter yakavakirwa pakugadzirwa kwesimba remagetsi rinokonzereswa kana zvinwiwa zvinokonzeresa mvura zvikacheka mitsetse yesimba remagineti mumunda wemagineti. Nokudaro, mvura yakayerwa inofanira kunge iine simba remagetsi rakati. Kana simba remagetsi remvura yakayerwa rakaderera zvakanyanya, senge mvura yakachena, peturu, doro, nezvimwe zvinwiwa zvisina kufambisa mvura kana kuti zvine simba shoma, electromagnetic flow meter haigone kugadzira zviratidzo zvakakwana zvinokonzereswa, zvichikonzera kuyerwa kusina kururama kana kutombobvira.
2. Ine huwandu hwakawanda hwezvinhu zve ferromagnetic kana mabubble: Kana mvura yakayerwa iine huwandu hwakawanda hwezvinhu zve ferromagnetic, inokanganisa simba remagineti re electromagnetic flow meter uye inokanganisa kunyatsoyera. Pamusoro pezvo, kuvapo kwehuwandu hwakawanda hwemabubbles mumvura kuchakanganisawo chiyero. Nekuti mabubbles achaita kuti conductivity yemagetsi yemvura isaenzane, uye mabubbles achagadzirawo simba remagetsi rinokonzereswa mumunda wemagineti, nokudaro zvichikanganisa chiratidzo chekuyera uye zvichikonzera zvikanganiso zvikuru mumhedzisiro yekuyera.
3. Nzvimbo dzine tembiricha yakakwira uye ine kumanikidzwa kwakakwira: Kunyangwe ma electromagnetic flow meter aine mamodheru akasiyana nezvinhu zvinogona kuchinjika kune imwe tembiricha uye kumanikidzwa, kana tembiricha yakakwira zvakanyanya kana kumanikidzwa kwakakwira zvakanyanya, zvinogona kukuvadza zvikamu zvakaita sema sensors uye linings e flow meter, zvichikanganisa mashandiro ayo uye hupenyu hwebasa. Kazhinji, tembiricha yakakodzera yema electromagnetic flow meter akajairika inowanzo kuve -20°C kusvika 120°C, uye kumanikidzwa kwacho kunenge 1.0MPa kusvika 4.0MPa. Kupfuura iyi parameter, ma electromagnetic flow meter akagadzirwa zvakanyanya uye ane kumanikidzwa kwakakwira anodiwa, asi ma flow meter akadaro anodhura.
4. Kuyerwa kwechiyero chekuyerera kwemvura yakaderera: Kururama kwekuyera kwema electromagnetic flow meter kuchakanganiswa nekuyerera kwemvura kwakaderera. Nekuti pakuyerera kwemvura kwakaderera, simba remagetsi rinokonzerwa nemagetsi diki, zvichiita kuti rive nyore kukanganiswa nezviratidzo zvekupindira kwekunze, uye kugadziriswa kwe flow meter kunogonawo kuganhurira kuyera kwakarurama kwekuyerera kwemvura kwakaderera. Kazhinji zvinokurudzirwa kuti chiyero chekuyera chekuyerera kwe electromagnetic flow meter chipfuure 0.3m/s kuti chive nechokwadi chekuti chiyero chakarurama.
5. Nzvimbo shoma yekuisa: Ma electromagnetic flow meter anoda hurefu hwakati hwezvikamu zvepombi dzakatwasuka usati waisa uye mushure mekushandisa kuti ave nechokwadi chekuti kuyera kwakarurama. Kazhinji, chikamu chepombi dzakatwasuka chinofanoda kuva nedhayamita yepombi ka5-10, uye chikamu chepombi dzakatwasuka chinofanoda kuva nedhayamita yepombi ka3-5. Kana nzvimbo yekuisa yakamanikana uye zvinodiwa zvezvikamu zvepombi dzakatwasuka zvisingakwanise kuzadzikiswa, zvinotungamira kune maitiro asina kugadzikana ekuyerera kwemvura, nokudaro zvichikanganisa kuyera kwakarurama. Muchiitiko ichi, zvingave zvakakosha kusarudza mamwe ma flow meter ane zvinodiwa zvishoma zvenzvimbo yekuisa.
6. Nzvimbo dzakasimba dzekudengenyeka: Munzvimbo dzakasimba dzekudengenyeka, masensa emagetsi ekuyerera kwemagetsi anokanganiswa nyore nyore nekudengenyeka, zvichikonzera zviratidzo zvekuyera zvisina kugadzikana uye kukanganisa kurongeka kwekuyera. Pamusoro pezvo, kudengenyeka kwakasimba kwenguva refu kunogonawo kukonzera kuti zvikamu zvemagetsi ekuyerera zvisununguke uye zvikanganiswe, zvichideredza kuvimbika kwayo uye hupenyu hwebasa. Naizvozvo, munzvimbo dzine kudengenyeka kwakasimba, senge pedyo nemidziyo mikuru yeindasitiri kana munzvimbo dzinodengenyeka nekudengenyeka kwenyika, matanho akakosha ekunyudzwa kweshock anofanirwa kutorwa pakushandisa magetsi ekuyerera kwemagetsi. Zvikasadaro, hazvikurudzirwi kuashandisa.
