Mumakemikari ekugadzira maworkshops, chiyero chemagasi akaomeswa anosarudza kunaka kwechigadzirwa; Mundima yekutarisa kwezvakatipoteredza, kupera kwegasi kuyerera data kune hukama nekubudirira kwekutonga kwezvakatipoteredza ... Muzviitiko izvi,thermal gas mass flow metersvave "chinhu chinopisa" muindastiri nekuda kwekugona kwavo kuyera kuyerera kwegasi pasina tembiricha uye muripo wekumanikidza. Uye sisitimu yedunhu kuseri kwayo i "smart brain" iyo inowana iyi yakanakisa kuita. Nhasi, tichakutora iwe kuti uiongorore!
Iyo yekupisa gasi mass flowmeter yakagadzirwa zvichibva pamusimboti wekupisa kwekupisa, uye inoshandisa inogara tembiricha musiyano nzira yekuyera nemazvo magasi. Iyo ine mabhenefiti ehukuru hudiki, yakakwira dhigirii redhijitari, kuisirwa nyore, uye kuyerwa kwakaringana.
Circuit musimboti module:
Sensor circuit:
Iyo sensor chikamu ine maviri mareferenzi level platinamu yekudzivirira tembiricha sensors. Kana chiridzwa chiri kushanda, imwe sensor inoramba ichiyera yepakati tembiricha T1; iyo imwe sensor inodziya kusvika kune tembiricha yakakwira kupfuura yepakati tembiricha T2 uye inoshandiswa kuona fluid kuyerera kwevelocity, inozivikanwa sevelocity sensor. Tembiricha Δ T=T2-T1, T2>T1. Kana mvura ichiyerera, mamorekuru egasi anodhumhana nesensor uye obvisa kupisa kweT2, zvichiita kuti tembiricha yeT2 iderere. Kuti uchengetedze Δ T nguva dzose, simba rekupa ikozvino reT2 rinoda kuwedzerwa. Iyo inokurumidza kuyerera kwegasi, iyo yakanyanya kupisa inobviswa. Pane hukama hwekushanda hwakagadziriswa pakati pehuwandu hwekuyerera kwegesi uye kuwedzera kwekupisa, iyo ndiyo nheyo yekusiyana kwekushisa nguva dzose.
Signal conditioning circuit:
Iwo masiginecha anobuda kubva kuma sensors anowanzo aine tsvina senge electromagnetic kukanganiswa uye ruzha rwezvakatipoteredza. Chiratidzo chekugadzirisa dunhu rakafanana ne "chiratidzo chekuchenesa tenzi", kutanga kushandisa bhiriji reWheatstone kukwidziridza husina simba hwekusiyanisa zviratidzo nemakumi kana kunyange mazana enguva, kusimbisa simba rechiratidzo; Zvadaro, kuburikidza ne-low-pass filtering circuit, high-frequency interference signals inosefa sesefa, ichichengeta chete masaini anoshanda ane chekuita nekuyerera kwegasi. Mushure mekunyatsokwenenzverwa kwakadaro, chiratidzo chinova chakachena uye chakagadzikana, chichiisa hwaro hwekuverenga kwakaringana kwekuyerera kwegasi.
Kugadziriswa kwedata uye dunhu rekukurukurirana:
Chiratidzo chakamisikidzwa chinopinda dunhu rekugadzirisa data uye chinorairwa nepamusoro-inoshanda microprocessor. Iyo microprocessor nekukurumidza uye nemazvo inoshandura tembiricha yekusiyanisa chiratidzo kuita gasi misa yekuyerera kukosha kwakavakirwa pane preset algorithm. Muchikamu chekubuda, mapuroteni ekutaurirana akawanda anotsigirwa, uye 4-20mA masaini masaini akakodzera echinyakare maindasitiri ekudzora masisitimu. HART kutaurirana, relay alarm, Ethernet transmission, 4G material network platform, Modbus RTU digital communication protocol inofambisa kuchinjana kwedata nemidziyo yakangwara uye makomputa epamusoro, kuona kuremerwa kwekutarisa uye automation control, uye kugonesa kuyerera kwegasi data "kumhanya".
Thethermal gas mass flowmeterinogadzirwa neAngji Instrument ine dhigirii sisitimu iyo, ine yakakwirira-chaiyo yekuyera kugona kwe ± 0.2%, inodzora kuyerera kwegasi mukati mechikamu chidiki kwazvo, inovandudza zvakanyanya kugadzikana kwechipi maitiro ekugadzira. Mumunda wegasi metering, wakatarisana nekumanikidza kwakaoma uye kushanduka kwekushisa mumapaipi, iyo yedunhu system yemhepo inopisa gasi inoyerera ine mukana wehuwandu hwakawanda (kusvika 100: 1). Kungave kuri kuyerera kwepombi yekudonha kuburitswa kana kuyerera kwekutengesa kwepamusoro, inogona kuyera nemazvo uye kubatsira mabhizinesi kuita manejimendi esimba.
Thethermal gas mass flowmeterdunhu, rine dhizaini yaro uye mabasa ane simba, inopa yakavimbika gasi kuyerera kuyerwa mhinduro dzekugadzirwa kwemaindasitiri, kutarisa kwezvakatipoteredza uye mamwe minda. Shanghai Angji Instrument Co., Ltd. ine maseketi ekupisa, anosanganisira akabatanidzwa plug-in, pombi, uye kupatsanurwa madziro akaiswa, uye anotsigira kugadzirisa nefoni.
