Munzvimbo dzekuchenesa tsvina, zvakaruramakuyerwa kwekuyereraZvinokosha zvikuru pakushanda zvakanaka uye kuchengetedzwa kwezvakatipoteredza. Michina yekuongorora mvura inoita basa rakakosha pakutarisa nekudzora kuyerera kwemvura yakasviba, tsvina, uye magasi.
Mhando dzeMichina yeKuyera Mvura Inoshandiswa Mukurapa Tsvina
Ma electromagnetic flowmeters anoshandiswa zvakanyanya mukugadzirisa tsvina nekuda kwekururama kwawo kwakanyanya uye kuvimbika. Anoshanda zvichibva pamutemo waFaraday we electromagnetic induction. Kana tsvina inoyerera nesimba remagineti, simba remagineti rinogadzirwa, uye hukuru hwesimba iri hunoenderana nekumhanya kwekuyerera. Ma flowmeters aya haana zvikamu zvinofamba, izvo zvinoderedza njodzi yekusakara. Anogona kuyera huwandu hwakasiyana hwekuyerera uye akakodzera kuyera mvura yakasviba uye inoparadza senge tsvina. Semuenzaniso, anowanzoiswa panzvimbo inopinzwa nekubuda kwefekitari yekurapa kuti aongorore kuyerera kwemvura yakasviba.
Ma ultrasonic flowmeters anoyera kumhanya kwekuyerera kwemvura achishandisa ma ultrasonic waves. Kune mhando mbiri huru: transit - nguva uye Doppler - effect ultrasonic flowmeters. Transit - time flowmeters inoverenga kumhanya kwekuyerera nekuyera mutsauko wenguva inotora kuti ma ultrasound waves afambe achikwira nekudzika mumvura. Doppler - effect flowmeters inoona frequency shift yema ultrasound waves inoonekwa nezvimedu kana mabubbles ari mutsvina. Ultrasonic flowmeters hadzipindi, zvinoreva kuti hadzidi kuiswa mupaipi, nokudaro zvichideredza mari yekuisa uye zvinogona kuvharika. Dzakakodzera kuyera kufamba kwetsvina isina kubikwa mumapaipi makuru.
Mapombi eVortex Shedding
Ma "vortex shedding flowmeters" anoshanda nekugadzira ma "vortices" mumvura painopfuura nepaipi. Kuwanda kwema "vortices" aya kwakabatana zvakananga nekumhanya kwekuyerera kwetsvina. Ane chimiro chiri nyore, kudonha kwesimba shoma, uye anogona kuyera huwandu hwakasiyana hwehuwandu hwekuyerera kwetsvina. Ma "vortex shedding flowmeters" anowanzo shandiswa kuyera kuyerera kwetsvina mumapaipi, sezvo achigona kubata hunhu hwetsvina hwakanyanya uye hwakasimba.
Mashandisirwo eFlowmeters muMaitiro eKurapa Tsvina
Kutarisa Kuyerera Kwemvura Kwakasimba
Pakupinda kwenzvimbo yekuchenesa tsvina, maflowmeter anoshandiswa kuyera huwandu uye mwero wekuyerera kwetsvina isina kucheneswa iri kupinda. Ruzivo urwu rwakakosha kune vanoshanda kuti vaone mutoro wekuchenesa uye kuronga huwandu hwemakemikari. Semuenzaniso, kana mwero wekuyerera kwetsvina ukawedzera kamwe kamwe, vanoshanda vangangoda kugadzirisa maitiro ekuchenesa kuti vave nechokwadi chekuti nzvimbo yacho inogona kubata huwandu hwakawedzerwa nemazvo.
Kudzora Kuyera Kwemakemikari
Mukurapa, kuyera kuyerera kwakarurama kwakakosha kune masisitimu ekuyera makemikari. Maflowmeter anobatsira kuona kuti huwandu hwakakodzera hwemakemikari, akadai semacoagulants uye mishonga inouraya utachiona, hunowedzerwa mumvura yakasviba. Semuenzaniso, panguva yekuuraya utachiona, flowmeter inoyera kuyerera kwemvura yakarapwa, zvichiita kuti chlorine ikwane zvakakwana zvinodiwa pakurapa.
Kuyerwa kweKuyerera kweMarara
Michina yekuyera mvura inoshandiswawo kuyera kuyerera kwetsvina mufekitari yekurapa. Izvi zvakakosha pakubata nekurasa tsvina. Nekuyera kuyerera kwetsvina nemazvo, vashandi vanogona kugadzirisa maitiro ekugadzirisa tsvina, zvakaita sekugaya mvura isina kunyorova kana kubvisa mvura. Semuenzaniso, kana mwero wekuyerera kwetsvina muchinhu chinogaya mvura chisina kunyorova wakakwira zvakanyanya kana kuti wakaderera zvakanyanya, zvinogona kukanganisa kushanda zvakanaka kwekugadzirwa kwemethane.
Kutarisa Kuyerera Kwemvura Yakasviba
Mvura isati yacheneswa yaburitswa munzvimbo yakapoteredza, maflowmeter anoshandiswa kuyera mwero wekuyerera kwemvura inoyerera uye huwandu hwayo. Ruzivo urwu haruna kukosha chete pakuona kuti mitemo yezvakatipoteredza inotevedzera mitemo chete asiwo pakuongorora kushanda kwese kwenzira yekurapa. Kana mwero wekuyerera kwemvura inoyerera wakanyanya kukwira kana kuti mhando yayo isingasvike pazvinodiwa, zvinoratidza kuti panogona kunge paine matambudziko ari munzira yekurapa ayo anofanira kugadziriswa.
Mukupedzisa, ma flowmeters zvinhu zvakakosha mumafekitori ekuchenesa tsvina.kuyerwakugona kunogonesa kushanda zvakanaka kwemaitiro ekurapa, kutevedzera mitemo yezvakatipoteredza, uye kuchengetedzwa kwezvakatipoteredza. Nekuvandudzwa kuri kuitwa tekinoroji, maflowmeter epamusoro-soro uye akavimbika achashandiswa muzvimbuzi zvekuchenesa tsvina, zvichiwedzera kuvandudza kushanda zvakanaka kwekurapa uye mhando.
