Chalk kwa Differential Pressure Transmitter

Muzochita zanthawi zonse, zida zingapo zimagwiritsidwa ntchito kuthandizira ma transmitters osiyanasiyana kuti agwire bwino ntchito. Chimodzi mwazofunikira kwambiri ndi ma valve manifold. Cholinga cha ntchito yake ndikuteteza sensa kuti iwonongeke kumbali imodzi ndikuyiyika pa transmitter kuchokera pakukonzekera, kukonza, kapena kusintha. Mavavu wamba a 3-valve amaphatikiza valavu imodzi yofananira ndi ma valve awiri ofananira ndi mbali yayikulu & yotsika ya transmitter. Ma valve onse amaphatikizidwa mu chipika chachitsulo cholumikizira chipinda cha transmitter kudzera munjira yolumikizira.

Kuyikako kukatha, kuti muyambe kuyeza, tsegulani valavu yofananira poyamba, kenaka tsegulani ma valve otchinga pamtunda wotsika komanso wothamanga kwambiri motsatizana. Yembekezerani mpaka kupanikizika kwa mizere kukhazikika, kutsekani valavu yofananira mwamphamvu ndikusiya ma valve otseguka, ndiye kuti chipangizocho ndi chokonzekera kupanikizika kosiyana kapena kuzindikira kutuluka. Kuti mulekanitse chopatsira, tsekani valavu yopingasa yothamanga kwambiri, tsegulani valavu yofananira ndikutseka valavu yocheperako kuti mutsimikize kuti kupanikizika kotsalira m'chipinda chotumizira kumasungidwa motsika momwe mungathere. Pamapeto pake, tsegulani zida zokhetsera magazi kuti muchotse kuthamanga kotsalira chidacho chitadulidwa.

Mtundu wina wodziwika wa DP transmitter ndi 5-valve manifold, yomwe imaphatikiza ma valve awiri otulutsa magazi pamaziko a 3-valve. Ma valve owonjezera opangira magazi amalola kuti mphamvu yotsalira itulutsidwe kumalo akutali m'malo moyandikira chipinda chachipinda.

Monga tafotokozera pamwambapa, kuthamanga kwapakati kotsalira kochuluka kuyenera kuchotsedwa musanachotse DP transmitter kuntchito. Mitundu ina yamitundu yambiri imatha kupereka ma valve okhetsa magazi pantchitoyo koma njira yodziwika bwino ndiyo kukhetsa magazi komwe kumayikidwa pabokosi lachipinda cha transmitter kudzera pa kulumikizana kwa ulusi. Masulani ndi kuchotsa mapulagi, ndi otsala sing'anga kuthamanga akanatha kutulutsa mpweya kuchokera orifices.

Pomaliza, zikuwonekeratu kuti ma transmitters a DP nthawi zambiri amaikidwa pamabulaketi. Mabotolo oyika mapaipi adapangidwa kuti azipereka njira yokhazikika yolumikizira ma transmitters a DP pamalo opangira. Amapangidwa makamaka ndi U-bolt ndi mbale yowongoka kapena L-mawonekedwe.

Monga odziwa zida wopanga kupereka yabwino fakitale zochita zokha njira, WangYuan amatha kukwaniritsa chowonjezera zosowa zathuWP3051 mndandanda wazinthu. Ngati muli ndi chikaiko kapena zofuna pa zipangizo pamwamba chonde omasuka kulankhula nafe.
