Ma Open Channel Flow Meters a Ngalande, Mitsinje ndi Madzi Otayira

Ma flow meter otseguka ndi zida zapadera zoyezera zomwe zimapangidwa kuti ziwerengere kuyenda kwa madzi m'madzi omasuka, kuphatikizapo mitsinje yachilengedwe, ngalande zothirira, ngalande zotulutsira madzi m'matauni ndi fakitale.madzi otayirangalande. Mosiyana ndi zoyezera kuyenda kwa madzi pogwiritsa ntchito mapaipi otsekedwa zomwe zimagwira ntchito pansi pa mikhalidwe yopanikizika kwambiri, zimagwiritsa ntchito mfundo yoyezera kuthamanga kwa madzi m'dera: kuchuluka kwa madzi m'derali kumafanana ndi dera la madzi lozungulira lomwe limachulukitsidwa ndi liwiro la madzi m'derali. Pali mitundu yambiri yamagetsi yomwe imagwirizana ndi mikhalidwe yosiyanasiyana yogwirira ntchito mumtsinje ndi m'njira zosiyanasiyana, iliyonse ili ndi kapangidwe kake, ubwino wake ndi zochitika zomwe zingagwiritsidwe ntchito.

Magulu Aakulu & Mfundo Zogwirira Ntchito

1. AkupangaMamita Oyenda a Njira Yotseguka

Uwu ndi mtundu wodziwika kwambiri wa ngalande zapakati ndi zazing'ono. Umagwiritsa ntchito choyezera cha ultrasonic chapamwamba kuti uyeze kuya kwa madzi nthawi yeniyeni, ndipo umaphatikizana ndi choyezera kuthamanga kwa madzi cha pansi pa madzi cha Doppler kuti ugwire liwiro la madzi. Kompyuta yolowera mkati imawerengera madzi nthawi yomweyo komanso mokulirapo kutengera magawo a geometric a channel monga m'lifupi, malo otsetsereka ndi mawonekedwe a gawo. Imathandizira ma flume ofanana a Parshall, ma weirs atatu ndi ma weirs amakona anayi kuti azitha kulondola kwambiri. Ndi kuyika pamwamba kosakhudzana, choyezera cha ultrasonic chimapewa kukhudzana ndi dothi, matope ndi zinyalala zoyandama. Chimapereka mawerengedwe okhazikika a ngalande zothirira, malo otulutsira zinyalala ndi njira zamadzi amvula mumzinda, ndipo chili ndi RS485, 4-20mA ndi kutumiza kwa IoT opanda zingwe kuti zitumizidwe deta yakutali. Cholepheretsa chake ndichakuti thovu lolemera, nthunzi yamadzi yokhuthala kapena algae yokhuthala yoyandama idzafooketsa zizindikiro za ultrasound ndikuchepetsa kulondola.

2. RadaraMamita Oyenda a Njira Yotseguka

Ma Radar flow meter amatulutsa zizindikiro za ma microwave zomwe zimayendera pafupipafupi kuti ziyeze kuchuluka kwa madzi ndi liwiro la madzi nthawi imodzi popanda kukhudza madzi. Ma microwave amalowa mu chifunga, nthunzi, thovu lochepa ndi fumbi lopepuka, zomwe zimapangitsa kuti zikhale zabwino kwambiri pa mitsinje yachilengedwe yokhala ndi malo akuluakulu pamwamba pa madzi, ngalande zazikulu zothirira madzi ndi ngalande zotulutsira madzi zomwe zimakumana ndi kusintha kwa kutentha ndi chinyezi pafupipafupi. Sensor imatha kuyikidwa pazitali za mlatho kapena m'mbali mwa mtsinje, zomwe sizifuna kumangidwa pansi pa madzi, zomwe zimachepetsa kwambiri ndalama zoyikira ndi kukonza. Imagwira ntchito bwino pa ntchito zowunikira kuyenda kwa madzi m'mitsinje komanso kuyeza kusefukira kwa madzi.

3. Ma Electromagnetic Area-Speed ​​​​flow Meters

Masensa othamanga amagetsi omwe ali pansi pa madzi amaikidwa pansi pa ngalande kuti ayesere liwiro la madzi, pomwe sensa yofanana ndi ya mulingo imatsata kuya kwa madzi. Imakwanira madzi oyenda ndi mpweya omwe amanyamula matope ambiri, madzi ochokera m'mbuyo mwa mgodi ndi madzi otayira a m'mafakitale okhala ndi tinthu tambiri tomwe timapachikidwa. Popanda zida zozungulira zamakina, sensayi imalimbana ndi kusweka ndi kutsekeka ndi matope ndi ulusi. Nthawi zambiri imagwiritsidwa ntchito m'njira zazikulu za zinyalala za m'mizinda komanso m'mitsinje yotulutsira madzi m'migodi, koma singathe kuyeza madzi oyera opanda mpweya wokwanira.

4. Njira Zachikhalidwe Zoyezera Kuyenda kwa Flume ndi Weir

Ma flume a Parshall, ma weirs amakona anayi ndi ma weirs amakona atatu a V ndi zida zoyambira zolumikizira. Pambuyo poyika ma flume kapena ma weirs okhazikika mu ngalande, kusiyana kwa mulingo wamadzimadzi musanayambe gawo lolumikizira kumapanga ubale wokhazikika wamasamu ndi kuchuluka kwa madzi. Kuphatikiza ndima transmitter a ultrasonic kapena hydrostatic level, dongosololi limawerengera madzi poyang'anira mutu wa madzi. Njira yotsika mtengo iyi imagwirizana ndi njira zazing'ono zothirira zokhazikika komanso malo otulutsira madzi m'fakitale okhazikika, koma imafuna kukumba nthawi zonse, chifukwa kusonkhanitsa matope pakhosi kudzasokoneza kwambiri deta yoyezera.

Zochitika Zofunikira Kwambiri

1. Ngalande Zothirira Ulimi: Yang'anirani kuchuluka kwa madzi omwe amagawidwa kuti mudziwe kuchuluka kwa madzi omwe amagawidwa m'minda komanso ziwerengero za kuchuluka kwa madzi omwe amaperekedwa.
2. Mtsinje Wachilengedwe & Kuyang'anira Zachilengedwe: Tsatirani kayendedwe ka mtsinje nthawi yeniyeni, kayendedwe ka zachilengedwe ndi kusefukira kwa madzi m'maofesi a hydrological ndi akuluakulu azachilengedwe.
3. Mayendedwe a Zinyalala ndi Madzi a Mvula ku Municipal: Kuyang'anira kutulutsidwa kwa madzi otayira m'fakitale, madzi amvula otuluka m'mizinda ndi kutuluka kwa madzi otayira m'mafakitale kuti akwaniritse miyezo yokhudzana ndi kutulutsidwa kwa mpweya woipa m'chilengedwe.
4. Mabowo Othira Madzi a M'mafakitale: Yesani fakitale ya mankhwala, mphero ya mapepala ndi madzi otuluka m'migodi kuti muyeze bwino momwe zinthu zilili komanso kuti muwongolere kuipitsidwa kwa mpweya.

Ubwino wa ZamakonoMamita Oyenda a Njira Yotseguka

Poyerekeza ndi njira yoyezera kuyenda kwa madzi yachikhalidwe ndi manja, mita yotsegulira njira zamakono imathandizira kuyang'anira yokha kwa maola 24, kusungira deta komanso kutumiza deta kutali ndi mitambo. Amasinthasintha kuti agwirizane ndi magawo osasinthasintha a mitsinje komanso kuchuluka kwa madzi oyenda kuyambira chilala mpaka kusefukira kwa madzi. Mitundu yambiri imakhala ndi IP68 yosalowa madzi, mphamvu zochepa zimagwiritsidwa ntchito komanso nthawi yayitali yogwira ntchito, zomwe zimachepetsa ntchito yowunikira ndi manja pafupipafupi. Mainjiniya amasankha mitundu yofanana ya mita malinga ndi kukula kwa njira, kuchuluka kwa matope, nyengo pamalopo komanso zofunikira zolondola kuti akwaniritse kuyang'anira kuyenda kwa madzi kwa nthawi yayitali kwa mitundu yonse ya mitsinje ndi njira zotseguka.
