Zvakanakira Nezvakaipa zveOpen – Channel Flowmeters

Nhanganyaya

Vhura - chiteshi chekufambisa mvurazvishandiso zvakakosha pakuyera mwero wekuyerera kwemvura mumigero pasina kuvharira mvura mupombi, senge muzvimbuzi zvekuchenesa mvura yakasviba, masisitimu ekudiridza, uye mukutarisa nzizi. Kunzwisisa zvakanakira nezvazvakaipira kwakakosha pakushandisa kwakakodzera.

Zvakanakira

Kubudirira kwemutengo

Zvichienzaniswa nedzimwe pombi dzakavharwakuyerwa kwekuyereramasisitimu,mita dzekufambisa dzechiteshi dzakavhurikaKazhinji zvinodhura zvishoma. Semuenzaniso, kuvaka flume kana weir, izvo zviri mhando dzezvivakwa zvekuyera kuyerera kwemvura zvakavhurika, zvinogona kunge zvisingadhuri zvakanyanya. Zvivakwa izvi zvinogona kugadzirwa nezvinhu zvakajairika senge kongiri kana simbi, uye hazvidi maitiro ekugadzira akaomarara. Kubudirira uku kunoita kuti zvikodzere kushandiswa pakukura kukuru, senge munzvimbo dzakakura dzekudiridza uko mutengo wekuisa michina yakaoma yekuyera kuyerera kwemvura unogona kunge wakanyanya.

Kuiswa Kuri Nyore

Kuiswa kwemita dzekufambisa dzechiteshi dzakavhurikaKazhinji zviri nyore. Zvinogona kuiswa pasina kukanganisa kwakanyanya kuyerera kwemvura kuripo. Semuenzaniso, muchina we ultrasonic open - channel flowmeter unogona kuiswa nekukurumidza padivi pemugero. Hapana chikonzero chekucheka mapaipi kana kuita shanduko huru munzira yekuyerera kwemvura. Kureruka kwekuisa uku kunoderedza nguva yekushanda, izvo zvinobatsira zvikuru mumasisitimu uko kuyerera kwemvura nguva dzose kwakakosha, senge mumafekitori ekuchenesa mvura yakasviba mumaindasitiri.

Mhando dzakasiyana dzemashandisirwo

Vhura - chiteshi chekufambisa mvuraZvinogona kuchinjika kumamiriro akasiyana-siyana emvura uye kuyerera kwemvura. Zvinogona kuyera kuyerera kwemvura, mvura yakasviba, uye kunyange mamwe madhaka ari mumigero yakashama. Mukutarisa nharaunda, zvinoshandiswa kuyera kuyerera kwenzizi, izvo zvinobatsira mukufanotaura mafashamo uye kutarisira zviwanikwa zvemvura. Munzvimbo dzemaindasitiri, zvinogona kubata kuyerera kwemvura ine kusviba kwakasiyana uye tsvina. Kugona kwadzo kushanda munzvimbo dzakasiyana kunoita kuti dzive sarudzo inoshanda kune mamwe maindasitiri akasiyana.

Kuongorora Zvinoonekwa

Nzira dzakawanda dzekuyera kuyerera kwemvura dzakavhurika, dzakadai semaweirs nemaflumes, dzinobvumira kuongororwa nemaziso. Vashandi vanogona kuona zvakananga kuyerera kwemvura pamusoro pechivako. Kusvika uku kwekuona kunobatsira mukuona nekukurumidza chero matambudziko akadai sekuvharika, maitiro asina kurongeka ekuyerera kwemvura, kana kunyura kwakawandisa kwemvura. Semuenzaniso, kana paine marara akaunganidzwa paweir, anogona kuonekwa nyore nyore uye kubviswa, zvichiita kuti kuyerwa kwekuyerera kwemvura kuve kwakarurama.

Kururama Kushoma

Vhura - chiteshi chekufambisa mvurakazhinji dzine kururama kwakaderera zvichienzaniswa nedzimwe pombi dzakavharikamita dzekufambaZvinhu zvakaita sekusiyana kwe geometry ye channel, kuomarara kwenzvimbo, uye kuvapo kwekutenderera kunogona kukanganisa kunyatsoyera. Semuenzaniso, mu rwizi rwechisikigo, chimiro chisina kurongeka che rwizi uye kuvapo kwematombo nemiti zvinogona kukonzera kuti kuyerera kwemvura kusaenzane, zvichikonzera kuverenga kusina kururama. Kururama kwema flowmeters e channel akazaruka kunowanzova pakati pe ± 5% kusvika ± 10%, izvo zvingasave zvakakwana kune zvinoshandiswa zvinoda kuyerwa kwekuyerera kwakanyatsojeka.

Kunzwisisa Mamiriro Ezvakatipoteredza

Ma flowmeter aya anonyanya kukanganiswa nekuchinja kwezvakatipoteredza. Kuchinja kwetembiricha kunogona kukanganisa huwandu hwemvura uye kusimba kwayo, izvo zvinogona kukanganisa kuyerwa kwekuyerera. Mumamiriro ekunze anotonhora, kuumbwa kwechando mugwara kunogona kukanganisa kuyerera kwemvura uye kuita kuti flowmeter ive isina kururama. Pamusoro pezvo, shanduko mukumanikidzwa kwe barometric dzinogona kukanganisa kuyerwa kwehuwandu hwekuyerera kwemvura, kunyanya mumasisitimu uko kuyerera kwemvura kuri pedyo nepamusoro. Semuenzaniso, mu flowmeter yakavhurika inoshandiswa munzvimbo yegungwa, shanduko mukumanikidzwa kwemhepo nekuda kwemadutu ari kuuya inogona kukonzera zvikanganiso mukuyerera kwemvura kwakayerwa.

Zvinodiwa zvekugadzirisa

Vhura - chiteshi chekufambisa mvurazvinoda kugadziriswa nguva dzose. Zvivako zvakaita semaweirs nemaflumes zvinogona kuunganidza madhaka, marara, uye kukura kwezvipenyu nekufamba kwenguva. Kuunganidzwa uku kunogona kuchinja hunhu hwekuyerera kwemvura uye kukanganisa kururama kwekuyera. Semuenzaniso, muhurongwa hwekuyerera kwemvura yetsvina hwakavhurika, madhaka nezvimwe zvinhu zvakasimba zvinogona kugara pamadziro eflume, zvichideredza nzvimbo inoshanda yekuyambuka uye zvichikonzera kuverenga kwemvura zvisiri izvo. Kuchenesa nekutarisisa nguva dzose kwakakosha kuti uve nechokwadi chekushanda zvakanaka, izvo zvinogona kutora nguva uye zvinodhura.

Kugadzirisa Kwakaomarara

Kugadzirisa ma "flowmeters" akavhurika kunogona kuoma. Sezvo maitiro ekuyerera kwemvura muma "open channels" achisiyana-siyana, kugadzirisa ma "flowmeter" nemazvo kuti atsanangure kusiyana uku kwakaoma. Maitiro ekugadzirisa mvura kazhinji anoda ruzivo rwakadzama rwe "channel geometry", "fluid properties", uye mamiriro ekuyerera kwemvura. Semuenzaniso, kana "channel" yakachinja zvishoma muchimiro chayo nekuda kwekukukurwa kwemvura, "calibration" ye "flowmeter" inofanira kugadziriswa zvinoenderana. Kugadzirisa kusina kunaka kunogona kukonzera zvikanganiso zvakakura mukuyera kuyerera kwemvura.

Mukupedzisa,mita dzekufambisa dzechiteshi dzakavhurikaZvine zvakanakira zvakawanda zvakaita sekushanda zvakanaka uye nyore kuisa, izvo zvinoita kuti zvikwanise kushandiswa mumabasa akawanda. Zvisinei, miganhu yazvo pakururama, kunzwisisa nharaunda, zvinodiwa pakugadzirisa, uye kuyera kwakaoma zvinofanirwa kufungwa nokungwarira pakusarudza mudziyo wekuyera kuyerera kwekushandisa kwakati.
