1. Kugona kweUltrasonic Flowmeters yeAcidic/Alkaline Solutions
Ehe, ma ultrasonic flowmeters anogona kuyera zvinobudirira mhinduro dzine acidic nealkaline, asi kukodzera kwawo kunonyanya kutsamira pakusarudza zvinhu zve transducer uye rudzi rwekuisa - zvinhu zviviri zvinotarisa zvakananga hunhu hwekuora kwemvura idzi. Kusiyana nema intrusive metres (semuenzaniso, electromagnetic flowmeters ane ma electrodes emukati) ayo anogona kuisa ngura kubva pakubatana zvakananga ne strong acids/bases, ultrasonic flowmeters (kunyanya ma clamp-on models) anoderedza kusangana kwemvura nekuisa ma transducers kunze kwepombi. Kune in-line ultrasonic flowmeters (uko ma transducers ari kusangana nemhinduro), kushandisa zvinhu zvinodzivirira ngura zvakaita se PTFE (polytetrafluoroethylene), ceramic, kana Hastelloy kunoita kuti ienderane nemvura dzine simba senge sulfuric acid, hydrochloric acid, kana sodium hydroxide. Chero bedzi transducer inoenderana ne corrosivity yemhinduro uye pombi (semuenzaniso, PVC, PVDF ye acidic fluids) inoenderana, ultrasonic flowmeters dzinochengetedza kushanda kwakasimba pasina kuora.
2. Mabhenefiti Akakosha Pamusoro Pemamita Echinyakare Emvura Dzinoparadza
Michina yekuongorora mvura ine ultrasonic inopa mabhenefiti akasiyana pakuyera mvura ine acidic/alkaline, ichigadzirisa matambudziko emhando dzechinyakare dzekuyera:
- Hapana Kupera Kunokonzerwa Nengura: Kusiyana nemakanika ekuyerera kwemvura (semuenzaniso, ma turbine metres) ane zvikamu zvinofamba zvinokanganisa nekupwanya, kana ma electromagnetic metres ane ma electrodes esimbi anowanzobatwa ne acid/alkali, ma ultrasonic flowmeters (clamp-on) haana zvikamu zvinosangana zvakananga nemushonga. Mamodheru ari mumutsara anoshandisa zvinhu zvisingashande, zvichibvisa kurasikirwa nekururama kunokonzerwa nengura kana kutadza kwemuchina.
- Hazvikanganisike neFluid Conductivity: Mhinduro dzeasidhi nealkaline dzinosiyana zvakanyanya mu conductivity (semuenzaniso, diluted acetic acid ine conductivity yakaderera, nepo concentrated sodium hydroxide ine conductivity yakakwira). Electromagnetic flowmeters dzinoshandisa fluid conductivity kuti dzishande uye dzinogona kutadza nema low-conductivity acids, asi ultrasonic flowmeters dzinoyera flow kuburikidza ne sound wave propagation— conductivity, viscosity, kana chemical composition ye solution hazvikanganisi kuverenga kwayo.
- Kuchengetedza Kushoma: Mvura inoora inowanzo kukonzera kugadziriswa kakawanda kwemamita echinyakare (semuenzaniso, kutsiva maelectrode ane ngura kana zvikamu zvemakanika). Ma ultrasonic flowmeters, asina zvikamu zvinofamba kana zvikamu zvinoora, anoda kungoongororwa nguva nenguva kwe transducer alignment kana mamiriro emadziro epombi, zvichideredza nguva yekushanda uye mari yekugadzirisa.
3. Zvinhu Zvakakosha Pakuyera Zvine Chekuita
Kuti pave nechokwadi chekuti mhinduro dzeacidic/alkaline dzinoyerwa nemazvo uye kwenguva refu, zvinhu zvitatu zvakakosha zvinofanirwa kukosheswa:
- Kuenderana kweTransducer Material: Sarudza zvinhu zvichienderana nesimba remushonga uye rudzi rwawo. Semuenzaniso, PTFE inoshanda kune akawanda maacid akasimba (kunze kwehydrofluoric acid yakakangwa inopisa), nepo maceramic transducers achibata maalkaline solutions anodziya zvakanyanya (semuenzaniso, 80°C sodium hydroxide). Dzivisa kushandisa masimbi transducers (semuenzaniso, simbi isina ngura) pamvura ine simba inoparadza, sezvo ichaora nekufamba kwenguva.
- Mamiriro Emapaipi Nezvinhu Zvayo: Paipi pachayo inofanira kuramba ngura—sarudzo dzakajairika dzinosanganisira PVDF (yeasidhi yakasimba), PVC (yeasidhi/zvigadziko zvakapfava), kana simbi yakafukidzwa negirazi (yemvura inoparadza inopisa zvakanyanya). Madziro epaipi akakuvara kana ane ngura anogona kukanganisa masaini e ultrasonic, zvichikonzera zvikanganiso pakuyera; ita shuwa kuti paipi haina ngura uye ine pamusoro wakatsetseka wemukati.
- Miganhu yeTembiricha neDzvinyiriro: Maasidhi/mabhesi akasimba anogona kushanda patembiricha yakakwira (semuenzaniso, sulfuric acid yemhando yepamusoro pa60–80°C) kana kumanikidzwa. Simbisa kuti chiyero chekushanda kwemuchina we ultrasonic chinoenderana netembiricha nedzvinyiriro yemushonga—kupfuura miganho iyi kunogona kukuvadza ma transducer kana kuderedza kururama kwechiratidzo. Pakushandisa tembiricha yakakwira, sarudza ma transducer anodzivirira tembiricha yakakwira (semuenzaniso, ma ceramic models akaongororwa kusvika ku150°C).
Pfupiso
Michina yemagetsi inoyerera ne ultrasonic isarudzo inoshanda uye yakavimbika yekuyera mhinduro dzine acidic ne alkaline, chero bedzi zvinhu zve transducer zvichienderana nekuora kwemvura, uye mamiriro emapaipi achizadzisa zvinodiwa zvepakutanga. Dhizaini yazvo isingapindi (yema clamp-on models) kana zvikamu zvinodzivirira ngura mukati, pamwe chete nekudzivirira kuputika kwemvura, zvinoita kuti zvive nani pane mita dzechinyakare munzvimbo dzinopisa. Nekutarisa kuenderana kwezvinhu, mamiriro emapaipi, uye miganhu yekushanda, michina yemagetsi inoyerera ne ultrasonic inopa chiyero chakarurama, chisina kugadziriswa zvakanyanya chekushandiswa kwemvura yemumaindasitiri, makemikari, kana tsvina inosanganisira mvura ine acidic/alkaline.
