Kuyeza mulingo kumatha kukhala gawo lofunikira kwambiri pamafakitale kuyambira pamafuta ndi gasi kupita kumankhwala amadzi. Pakati pa matekinoloje osiyanasiyana omwe alipo, ma transmitters a pressure and differential pressure (DP) amagwiritsidwa ntchito kwambiri ngati zida zowunikira kuchuluka kwa madzimadzi. Pachimake, muyeso wotengera kupanikizika wokhazikitsidwa pa mfundo ya hydrostatic pressure, mphamvu yoperekedwa ndi madzimadzi popuma chifukwa cha mphamvu yokoka. Kuthamanga kulikonse muzakudya zamadzimadzi kumayenderana ndi kutalika kwa pamwamba pa mfundoyo, kachulukidwe kake, ndi kuthamanga kwa mphamvu yokoka. Mgwirizanowu umawonetsedwa ndi formula:
P = × g × h
Kumene:
P = Kuthamanga kwa Hydrostatic
ρ = Kuchuluka kwamadzimadzi
g = Kuthamanga kwa mphamvu yokoka
h = Kutalika kwa gawo lamadzimadzi
Sensa yothamanga yomwe ili pansi pa thanki imatha kuyeza kuthamanga uku, kenaka kuwerengera mlingo wamadzimadzi ndikuusintha kukhala chizindikiro chamagetsi kudzera mumayendedwe malinga ngati kachulukidwe kakang'ono kakudziwika.
Ma Pressure and Differential Pressure Transmitters atha kugwiritsidwa ntchito poyeza mulingo, koma ntchito zawo zimasiyana kutengera momwe amagwirira ntchito:
Pressure Transmitter
Muyeso:Kupanikizika kokhudzana ndi kuthamanga kwa mumlengalenga.
Kagwiritsidwe:Ndi abwino kwa akasinja otseguka kapena ngalande pomwe madzi amadzimadzi amawonekera mumlengalenga. Mwachitsanzo, m'malo osungiramo madzi, zotulutsa za transmitter zimayenderana ndi kuchuluka kwa madzi.
Kuyika:Amayikidwa pansi pa thanki kapena kumizidwa pansi pamadzimadzi.
Differential Pressure (DP) Transmitter
Muyeso:Kusiyana pakati pa zovuta ziwiri: kuthamanga kwa hydrostatic pansi pa thanki ndi kuthamanga pamwamba pamadzimadzi.
Kagwiritsidwe Ntchito:Zofunikira pamatangi otsekedwa / opanikizidwa pomwe kupanikizika kwamkati (kuchokera ku mpweya, nthunzi, kapena vacuum) kumakhudza muyeso. Muyezo wa DP umatha kubweza kusokoneza ndikuwonetsetsa kuti zidziwitso zolondola.
Kuyika:Mbali yothamanga kwambiri imalumikizana ndi maziko a thanki pomwe mbali yotsika kwambiri imalumikizana pamwamba pa thanki.
Kukhazikitsa kofunikira pakuyezera motengera kukakamizidwa
Kuchita Zokwera:Ma transmitters amayenera kuyikidwa pamalo otsika kwambiri kuti asawume. Mapangidwe a chotengera ndi momwe zimakhalira ziyenera kuwonetsetsa kuti masensa oyenda pansi pamadzi amatha kumizidwa pansi mosalekeza. Machubu amphamvu a DP transmitter akuyenera kukhala opanda zotchinga, kutayikira, komanso thovu la mpweya.
Zachilengedwe ndi Zapakatikati:Kulumikizana kwakutali kwa capillary kungagwiritsidwe ntchito kudzipatula ku zomverera kutentha kuti ziteteze kuwonongeka kwamagetsi kuchokera ku kutentha kwamadzi kwambiri. Kulumikizana kwa njira ndi zisindikizo za diaphragm kapena zida zolimbana ndi dzimbiri zimatha kuteteza sensa kumadzimadzi aukali. Kuthamanga kwa ma transmitter kuyenera kupitilira kuthamanga kwambiri kwa magwiridwe antchito kuphatikiza zochitika zapaulendo.
Zapamwamba ndi Kuphatikiza:Ukadaulo wamakono utha kuyambitsidwa kuti uthandizire kudalirika kwa zida. Kuyankhulana kwanzeru kumathandizira kuphatikizika kosalala ndi machitidwe owongolera komanso zowunikira zenizeni zenizeni zomwe zimachenjeza zolakwika kapena kutsekeka. Ma transmitters osiyanasiyana omwe amayesa mulingo ndi kutentha nthawi imodzi amatha kupangitsa kukhazikitsa ndikuchepetsa mtengo.
Ma transmitters okakamiza komanso osiyanitsa ndi zida zosunthika zoyezera mulingo, zomwe zimapereka zotsika mtengo komanso zosinthika m'mafakitale onse.Shanghai Wangyuanndi wodziwa kupanga zida zoimbira zida. tingasangalale kumva kuchokera kwa inu, ngati mukufuna njira zowunikira.
