Mumunda wekuyerwa kwekuyerera, ma "multi-channel ultrasonic flow meters" akabuda semhinduro inoshanda zvikuru uye yakavimbika, ichipa mabhenefiti akasiyana-siyana pamusoro pemidziyo yekuyera kuyerera kwechinyakare. Mabhenefiti aya anoita kuti awedzere kufarirwa mumaindasitiri akasiyana-siyana, kubva pakuchenesa mvura nemvura yakasviba kusvika kumafuta negasi, uye kubva pakugadzira magetsi kusvika pakugadzirisa makemikari.
Kururama Kwekuyera Kwakakwirira
Mamita ekuyerera eultrasonic ane migero yakawandaZvakagadzirirwa kuwana kururama kunoshamisa mukuyera kuyerera. Nekushandisa nzira dzakawanda, dzinogona kubata velocity profile yemvura zvakanyatsojeka. Channel yega yega inoyera velocity yekuyerera panzvimbo dzakasiyana mukati mepombi. Iyi nzira yekuyera mapoinzi akawanda inoderedza zvinobudirira kukanganisa kwekukanganiswa kwekuyerera, senge kunokonzerwa nemagokora, mavharuvhu, kana mapombi ari mupombi. Semuenzaniso, zvichienzaniswa nema single-channel ultrasonic flow metres kana mamwe ma velocity-type flow metres senge electromagnetic flow metres, multi-channel ultrasonic flow metres haanyanyi kunetseka nezvipingamupinyi zvekukwira. Musystem yakaiswa zvakanaka, ine zvinodiwa zvakajairika zvezvikamu zve 5D upstream ne 2D downstream straight inlet pipe (apo D iri dhayamita yepombi), kururamisa kwekuyera kwema multi-channel ultrasonic flow metres kunogona kusvika pa 0.5%. Kusiyana neizvi, kudzokororwa kwema electromagnetic flow metres kazhinji kunongova 1/3 yekururama uku, uye kwe single-channel ultrasonic flow metres kunenge 1/5. Kururama uku kwakakosha mumashandisirwo apo kuyerwa kwekuyerera kwakanyatsokosha, senge mukutengeserana, uko kuyerwa kwakarurama kwehuwandu hwemvura kunokanganisa zvakananga kutengeserana kwemari.
Chinodiwa Chakaderera Chezvikamu zvePaipi Yakatwasuka
Imwe mukana mukuru wemamita ekuyerera kwemvura ane nzira dzakawanda iri mukushaikwa kwadzo kushoma kwezvikamu zvepombi dzakatwasuka. Dzinoshandisa nzira yekubatanidza kaviri kuti dziverenge kuyerera kwadzo zvichibva pakugoverwa kwekukurumidza uye kugoverwa kwenzvimbo. Iyi algorithm yepamusoro inovagonesa kuyera kuyerera kwacho nemazvo mumamiriro ekuyerera kwemvura ane nzira dzakatwasuka uye dzakavhurika, zvichiita kuti kuyera kwacho kuve kwakarurama. Nekuda kweizvozvo, dzinogona kushanda zvinobudirira nehurefu hwepombi dzakatwasuka hupfupi zvichienzaniswa nemamwe mamita ekuyerera. Semuenzaniso, nepo mamwe mamita ekuyerera echinyakare angada 20D kana kupfuura epombi dzakatwasuka kumusoro kuti dziyereswe nemazvo, mamita ekuyerera emvura ane nzira dzakawanda anowanzoda 10D kumusoro uye 3D pasi. Kuchinjika uku mukuisa ibhenefiti huru, kunyanya mumamiriro ezvinhu apo nzvimbo yakaganhurirwa kana apo kugadzirisa marongerwo epombi iripo kuti igare zvikamu zvepombi dzakatwasuka refu kunodhura kana kusashanda. Zvinobvumirawo kuiswa kwakawanda munetwork dzakaoma dzemapombi, zvichiwedzera huwandu hwemashandisirwo apo aya mamita ekuyerera anogona kushandiswa.
Kunzwa Kwakanyanya
Mamita ekuyerera eultrasonic ane migero yakawandazvinoratidzwa nekukwanisa kwazvo kuyerwa. Kunyatsojeka kwekuyera nguva mumamita aya kwakanyanya, kazhinji kusvika padanho repicosecond. Kunyatsojeka uku pakuyera nguva kunoita kuti vakwanise kuyerwa nekumhanya kwakarurama kunyangwe pakumhanya kwakaderera. Semuenzaniso, vanogona kuyera nekumhanya kwakarurama nekumhanya kwakaderera se0.5 m/s nekunyatsojeka kwe0.5%. Kunzwa uku kunonyanya kukosha mumashandisirwo apo mwero wekuyerera unogona kusiyana zvakanyanya, kusanganisira mamiriro ekuyerera kwakakwirira uye kwakaderera. Chiyero chehupamhi hwakakura, chinogona kusvika pa400:1, zvinoreva kuti izvimita yekuyereras inogona kuyera zvinobudirira kuyerera kwemvura kuburikidza nehupamhi hwakakura, kubva pakuyerera kwakaderera panguva yekumirira kana nguva yekudiwa kushoma kusvika pakuyerera kwakakwira panguva yekushanda kwakanyanya. Kugona uku kubata huwandu hwakasiyana hwekufamba kwemvura pasina kukanganisa kururama kunoita kuti mita yekuyerera ye ultrasonic ine nzira dzakawanda yakakodzera maitiro akasiyana-siyana emaindasitiri uko kushanduka kwekufamba kwemvura kwakajairika.
Kuchinjika kuMafuta Akakombama uye Mamiriro Ekushanda
Aya ma flow metres anokwanisa kushandiswa zvakanyanya kumhando dzakasiyana dzemvura uye mamiriro ekushanda akaoma. Nheyo yavo yekuyera ultrasonic haikanganisike nemaitiro akawanda emvura, akadai sekupisa, kumanikidzwa, uye viscosity mukati memhando dzakasiyana. Izvi zvinoita kuti zvikodzere kuyera mhando dzakasiyana dzemvura, kusanganisira mvura yakachena, mvura yegungwa, acids, alkalis, mafuta, uye kunyange mvura ine huwandu hwakati hwezvinhu zvakasimba zvakamiswa kana mabubbles (kunyangwe kuvapo kwezvakasimba zvakanyanya kana mabubbles kuchiri kukanganisa, anowanzoita zviri nani kupfuura mamwe marudzi mazhinji ema flow metres mumamiriro ezvinhu akadaro). Pamusoro pezvo, multi-channel ultrasonic flow metres inogona kushanda munzvimbo yakakura yekupisa, kubva -10°C kusvika 150°C muzviitiko zvakawanda, uye inogona kutsungirira kumanikidzwa kwakanyanya, zvichiita kuti ikodzere kushandiswa munzvimbo dzakaoma dzemaindasitiri. Semuenzaniso, mumapaipi emafuta negesi, uko mvura inogona kunge iri musanganiswa wakaoma wemahydrocarbon ane tembiricha dzakasiyana uye kumanikidzwa, multi-channel ultrasonicmita dzekuyererainogona kupa data rakavimbika rekuyera kuyerera kwemvura.
Kusapindira uye Kugadzirisa Kwakaderera
Vazhinjimita dzekuyerera dze ultrasonic dzakawandainopa sarudzo yekuyera isingapindire, kunyanya iyo ine masensa ekunze e ultrasonic anovhara. Iyi nzira yekuisa isingapindire haidi kucheka kana kugadzirisa pombi, izvo zvinoita kuti nzira yekuisa ive nyore uye inoderedza mari yekuisa. Inoderedzawo njodzi yekudonha kana kukanganiswa kwekuyerera kwemvura. Uyezve, sezvo masensa asingasangani zvakananga nemvura, haawanzo ngura, kukurwa, kana kusvibiswa, izvo zvinoderedza zvakanyanya zvinodiwa pakugadzirisa. Kusiyana neizvi, mita dzemvura dzinopinda dzine zvikamu zvinofamba kana zvikamu zvinosangana zvakananga nemvura zvinogona kuda kugadziriswa nguva nenguva, kugadziriswa, uye kutsiviwa nekuda kwekusakara kana kukuvara kubva mumvura. Kunyangwe kune masensa e ultrasonic anongopinda zvakananga anosangana nemvura, akawandamita dzekuyerera dze ultrasonic dzakawandadzakagadzirirwa kubvumira kuyerera kwemvura nguva dzose uye kuiswa kwepressure uye kugadziriswa online. Izvi zvinoreva kuti kana sensor ikakanganiswa nekukweva kana zvimwe zvinetso nekufamba kwenguva, inogona kubviswa uye kugadziriswa pasina kudzima sisitimu yese yemapaipi, zvichiita kuti irambe ichishanda uye ichideredza nguva yekudzima.
Kuenderana uye Kuenderana
Mamita ekuyerera kwemagetsi emhando dzakasiyana-siyana anogona kushandiswa zvakasiyana-siyana uye anoenderana nemasisitimu akasiyana-siyana emaindasitiri. Anogona kubatanidzwa zviri nyore nemamwe maturusi ekudzora mashandiro uye ekutarisa. Semuenzaniso, anowanzo uya nema interfaces akajairwa ekutaurirana akadai seRS485, ayo anobvumira kutaurirana kusina musono ne programmable logic controllers (PLCs), distributed control systems (DCSs), kana mamwe ma data acquisition and control systems. Izvi zvinogonesa kutarisa nekudzora flow rate panguva chaiyo, pamwe nekubatanidzwa kwe flow data mumasystem ese ekutarisira plant. Pamusoro pezvo, mamwe ma multi-channel ultrasonic flow metres anogona kugadzirirwa ma temperature sensors kuti aone flow ne heat panguva imwe chete (kana ari maapplication ekupisa kana kutonhora), achipa data rakazara re manejimendi yesimba uye kugadzirisa process. Anogona zvakare kugadziriswa kuti asvike kune zvinodiwa zve application, zvakaita semapombi akasiyana, zvinhu, uye kuyera kwakarurama, zvichiita kuti akwane mumaindasitiri akasiyana-siyana nemaapplication.
Mukupedzisa, ma "multi-channel ultrasonic flow meter" ane mabhenefiti akawanda anoita kuti ave sarudzo inokwezva zvinodiwa pakuongorora kuyerera kwemazuva ano. Kururama kwawo kwakanyanya, zvinodiwa pachikamu chepaipi chakatwasuka, kunzwa kwakanyanya, kugona kuchinjika kumvura yakaoma nemamiriro ezvinhu akaomarara, kusapindira, kusachengetedza kwakaderera, uye kushanduka-shanduka kunoita kuti ave mhinduro inotungamira mumunda we "fluid"kuyerwa kwekuyerera, zvichikurudzira kushanda zvakanaka, kururama, uye kuvimbika mumaindasitiri pasi rose.
