Kurapa kwemvura uye kugovera mabasa kwakaomarara, kunosanganisira kufambisa mvura kubva kune imwe nzvimbo kuenda kune imwe, kuwedzera filtration pressure, kubaya makemikari ekuchenesa mvura, uye kugovera mvura yakachena kunzvimbo dzekushandisa.Kururamisa uye kuvimbika kunonyanya kukosha kana uchishandisa pombi inodzorwa metering. sechikamu chemakemikari uye ekuwedzera jekiseni system mukugadzirisa mvura.Iyo electromagnetic flowmeter inogona kuve mhinduro inoshanda yekuona mashandiro chaiwo emidziyo kuti ive nechokwadi chekushanda kwakanyanya kwemakemikari dosing process.
Dedicated feed systems dzinoshandiswa kupa makemikari kune ese matanho emvura uye tsvina yemvura.Iyo nzira yekuchenesa mvura inoda optimal synthesis, saka makemikari angada kuwedzerwa kuti agadzire nzvimbo yakanaka yekukura kwehupenyu.Izvo zvakakoshawo kuwana alkalinity yakakwana chengetedza pH inodiwa yekushanda.
Sechikamu chejekiseni remakemikari, zvinowanzodiwa kuwedzera asidhi kana caustic kudzora pH, kuwedzera ferric chloride kana alum kubvisa zvinovaka muviri, kana kuwedzera supplementary carbon sources semethanol, glycine kana acetic acid yekuvandudza nzira. nzira yekuchenesa mvura, vashandi vemiti vanofanira kuona kuti huwandu hwakarurama hunowedzerwa kuhutano sechikamu chekutonga kwehutano.Kunyanya kana kushoma kushandiswa kwemakemikari kunogona kukonzera kudhura kwekushandisa, kuwedzera kwehuwandu hwekuora, kugara uchigadzirisa midziyo, nezvimwe zvakashata. migumisiro.
Imwe neimwe kemikari yekudyisa system yakasiyana, zvichienderana nerudzi rwekemikari inopombi, kusungirirwa kwayo, uye chiyero chinodiwa chekudya.Mapombi ekuyera anogona kushandiswa sechikamu chenzira yekujoinha makemikari muhurongwa hwekurapa kwemvura.Izvi zvinowanzo kuwanikwa mukati tsime remvura mashandiro.Chiyero chidiki chekudya chinoda pombi ine metered iyo inogona kupa chaiyo dose yekemikari kune inotambira rwizi.
Muzviitiko zvakawanda, iyo metering pombi inoshandiswa mumvura yekuchenesa mvura ndeye yakanaka displacement kemikemikari metering device inogona kushandura simba nemaoko kana kuti otomatiki maererano nezvinodiwa nemamiriro ekugadzirisa.Iyi pombi inopa huwandu hwepamusoro hwekudzokorora uye inogona kupomba. zvakasiyana-siyana zvemakemikari, kusanganisira acids, alkalis uye zvinhu zvinoparadza kana viscous zvinwiwa uye slurries.
Mishonga yekuchenesa mvura inogara ichitsvaga nzira dzekugadzirisa mashandiro avo nekuderedza kuchengetedza, kuderera, kuputsika uye zvimwe zvinhu.Chinhu chimwe nechimwe chinokanganisa kushanda zvakanaka uye kubereka.Asi kana zvabatanidzwa, zvichakanganisa zvakanyanya kugadzirwa kwefekitori uye pasi.
Nzira chete yekuziva kuisa jekiseni rakakodzera rekemikari yakapihwa muchirongwa chekurapa kwemvura ndeyekuona iyo chaiyo dhizaini inochengetedzwa nepombi yemamita. Dambudziko nderekuti mapombi mazhinji emajekiseni emakemikari haabvumiri mushandisi kudhaya zvachose. zvigadziriso zvemwero chaiwo wedosi.
Chiitiko chakaratidza kuti kushandiswa kwemamita ekuyerera kwekugadzirisa kushanda kwepombi kunogona kupa ruzivo rwakakosha pamusoro pekushanda kwepombi uye kururamisa kwemaitiro emugadziri.Inogonawo kuona matambudziko ekushanda uye kuderedzwa kwekushanda nekuda kwechikamu chekupfeka kana mamwe mamiriro.Nekuwedzera kuyerera kwemamita uye mavharuvhu pakati pepombi uye maitiro, vashandisi vanogona kuwana ruzivo rwekuongorora kushanda kweiyo chaiyo midziyo, kuratidza chero misiyano, uye kugadzirisa kumhanya kwepombi pazvinenge zvichidikanwa.
Mhando dzakawanda dzemamita ekuyerera dzinoyera zvinwiwa, uye dzimwe dzakanyanya kukodzera nzvimbo dzekuchenesa mvura netsvina kupfuura dzimwe.Mamwe mamita akanyatsorurama uye anodzokororwa kupfuura mamwe.Mamwe anoda kushoma kana kuoma kwekugadzirisa, uye mamwe anogara kwenguva refu kupfuura mamwe.Zvakakosha kutarisa zvose zvinosarudzwa uye kwete kungotarisa pane chimwe chinhu, zvakadai semutengo.Tichifunga nezvezvinodiwa zvekushanda nekugadzirisa mabasa, mitengo yakaderera yekutenga inowanzova chiratidzo chinotsausa.Chiyero chiri nani imari yose yevaridzi (TCO), iyo inofunga kwete chete mutengo wekutenga, asiwo mutengo wekuisa, kugadzirisa, nekutsiviwa kwemamita.
Tichifunga nezve mutengo, huchokwadi uye hupenyu hwesevhisi, magetsi emagetsi anoyerera anogona kuve sarudzo yakanaka yekuda kucheneswa kwemvura.Tekinoroji yekuyera yeElectromagnetic inobvisa kudiwa kwezvikamu zvinofamba, izvo zvinogona kukonzeresa kuita uye kugadzirisa nyaya kana ichishandiswa mumvura ine yakakwira solids content.The electromagnetic flowmeter inogona kuyera inenge chero ipi zvayo conductive fluid, kusanganisira nzira yemvura uye wastewater.Mamita aya anopa kuderera kwepasi, kuwedzera kutendeuka kwehuwandu uye yakanakisa repeatability.Ivo vanozivikanwa nekupa yakakwirira yakarurama mazinga pamutengo unonzwisisika.
Iyo electromagnetic flowmeter inoshanda zvinoenderana nemutemo waFaraday we electromagnetic induction kuyera fluid velocity.Mutemo unoti kana conductor ikafamba mumagnetic field, chiratidzo chemagetsi chinogadzirwa muconductor, uye chiratidzo chemagetsi chinoenzanirana nekumhanya kwemvura. kufamba mune magnetic field.
Zvichienderana nehuwandu hwemvura uye / kana mvura yemhando, simbi isina tsvina (AISI 316) maelectrodes anoshandiswa mumagetsi akawanda emagetsi ekuyerera anogona kukwana.Zvisinei, magetsi aya anoiswa pasi pegomba uye kuputika munzvimbo dzinoparadza, izvo zvinogona kukonzera kurongeka kwemagetsi. flowmeter kuti ichinje nekufamba kwenguva.Vamwe vagadziri vezviridzwa vakachinja kuHastelloy C electrode seyakajairwa zvinhu kuti zvipe zvirinani kusagadzika kwecorrosion uye hupenyu hwesevhisi hurefu.Iyi superalloy ine kupikisa kwakanyanya kune corrosion yenzvimbo, iyo inobatsira munzvimbo dzine chloride-ine kutonhora kwakanyanya. Nekuda kweiyo chromium uye molybdenum zvirimo, ine yakakwira mwero we-round corrosion resistance.Chromium inowedzera kupikisa kune oxidizing mamiriro, uye molybdenum inowedzera kushorwa nekuderedza nharaunda.
Vamwe vagadziri vanoshandisa Teflon lining pane yakaoma rabha lining kuti vape yakakwira tembiricha inodzivirira zvinhu zvine makemikari akasimba.
Chokwadi chakaratidza kuti electromagnetic flowmeters akanyatsokodzera kune yakakosha majekiseni emakemikari munzvimbo dzekurapa mvura. Dzinogonesa vanogadzira zvirimwa kuyera nemazvo huwandu hwemvura inopfuura nemavari. Mamita aya anogona kushandiswa sechikamu chekuvhara-loop system kutumira zvinobuda. kune programmable logic controller (PLC) kuti ione chiyero chemakemikari munguva ipi zvayo yenguva.Ruzivo urwu runobatsira kugadzirisa mari yemakemikari uye kugadzirisa mitemo inoshanda yezvakatipoteredza.Vanopawo zvakakosha mararamiro ehupenyu hwekuchenesa uye kugovera zvivako. + 0.25% kunyatsoita pasi pepasi pemamiriro emvura anoyerera. Panguva imwecheteyo, iyo isina-invasive, yakazaruka inoyerera tube configuration inenge inobvisa kudzvinyirira kurasikirwa.Kana yakataurwa zvakanaka, mita inenge isingagadziriswi ne viscosity, tembiricha, uye kumanikidzwa, uye ipapo. hapana zvikamu zvinofamba zvinotadzisa kuyerera, uye kugadzirisa uye kugadzirisa kunochengetwa kuri kushoma.
Munzvimbo inoda kurapwa kwemvura, kunyangwe iyo yakanyanya-saizi metering pombi inogona kusangana nemamiriro ekushanda akasiyana kubva pane zvinotarisirwa.Nekufamba kwenguva, kugadzirisa kwemaitiro kunogona kushandura density, kuyerera, kudzvanywa, tembiricha, uye viscosity yemvura iyo pombi inofanirwa kubata. .
