Guided Wave Radar (GWR) chishandiso chekuyera mazinga e microwave reflection-based chinoshandiswa nekushandisa kwayo simbi probe (waveguide) kutungamira kupararira kwechiratidzo che microwave. Inoita kuti kuyera kwakanyatsojeka mazinga emvura, ma interfaces, kana mavhoriyamu ezvishandiso zvakaita sezvinwiwa, zvimedu zvakasimba, kana slurries. Kusiyana nemamita e radar level asingabatanidzwe, ma microwave signals eGWR haapararire mumhepo asi anofamba akananga pamwe chete ne probe, zvichiipa mabhenefiti akasiyana mumamiriro ezvinhu akaomarara ekushanda. Pazasi pane sumo yakadzama inofukidza musimboti wayo wekushanda, zvikamu zvikuru, zvinhu zvakakosha, mamiriro ekushandiswa, uye zvipingamupinyi.
I. Nheyo yekushanda
Guided Wave Radar inogadzira masaini e microwave ane frequency yakakwira (kazhinji 6GHz kana 26GHz) kuburikidza ne transmitter module. Masaini aya anotungamirwa kuburikidza nema probes esimbi akasarudzika (semuenzaniso, tambo dzesimbi, tsvimbo dzakasimba, tambo dze coaxial) pamusoro pechinhu chiri mukati. Kana masaini e microwave akasangana ne interface pakati pechinhu chiri mukati nemhepo, chikamu chechiratidzo chinoratidzwa uye chinodzokera shure ne probe kuenda ku module inogamuchira. Chishandiso ichi chinoverenga kukwirira kwenhanho nekuyera musiyano wenguva (kana musiyano wefrequency) pakati pekutumira masaini nekufungisisa, pamwe chete nekumhanya kwekupararira kwema microwave ari mukati.
- Fomura Yepakati: Kureba kwenhanho H=2v×t, apo v iri kumhanya kwekupararira kwema microwave ari muprobe, uye t ndiyo nguva yekudzoka kwechiratidzo.
- Kutarisa Zviratidzo: Chinoongorora chinoisa simba rema microwave munzvimbo diki, zvichidzivirira nyaya yekusiyana kwemasaini eradar asingabatanidzi anopararira mumhepo, zvichikonzera masaini akasimba uye akagadzikana anoratidzwa.
II. Zvikamu Zvikuru
Radar yeGuided Wave ine chimiro chakati wandei, chinosanganisira zvikamu zvinotevera:
- Chigadzirwa cheMagetsi: Chine basa rekugadzira, kutumira, kugamuchira, uye kugadzirisa masaini e microwave. Chinosanganisira microprocessor yakavakirwa mukati mekuverenga uye kubuda kwedata (semuenzaniso, masaini e4-20mA, HART, RS485).
- Probe (Waveguide): "Nzira yekutumira" yezviratidzo zve microwave, ine mhando dzakajairika dzinosanganisira:
- Rigid Rod Probes: Yakakodzera zvinwiwa zvine viscosity shoma uye mamiriro asina kugadzikana, zvichipa simba rakasimba rekudzivirira kutenderera.
- MaProbes eSimbi: Akanakira matangi akadzika, midhiya ine viscosity yakakura, kana ayo ane zvinhu zvakasimba zvakasungirirwa, zvichipa kuchinjika kwakanyanya.
- MaCoaxial Probes: Zviratidzo zvinofamba pakati pemaconductor emukati neekunze, zvakakodzera kune low dielectric constant media (semuenzaniso, mafuta akareruka, magasi ane liquefied) ane kugona kwakawedzerwa kwekudzivirira kukanganiswa.
- Flange/Interface Yekuisa: Inochengetedza mudziyo pamusoro petangi, nezvinhu zvakasarudzwa zvichibva pakuora kwepakati (semuenzaniso, 316L stainless steel, Hastelloy).
III. Hunhu Hunokosha
1. Kukwanisa Kwakasimba Kwekudzivirira Kukanganiswa Kwemamiriro Akakomba
- Zviratidzo zvema microwave zvinofamba nepa probe, zvichideredza kukanganiswa kwezvinhu zvakatipoteredza zvakaita seutsi, guruva, furo, kana mhute. Zvinoramba zvakagadzikana kunyangwe munzvimbo dzine furo rakawanda (semuenzaniso, matangi ekuvirisa doro) kana kana paine kuvhundutswa kwakanyanya.
- Dzinodzivirira kukanganiswa nezvivako zvemukati metangi (semuenzaniso, zvinokurudzira, zvinokanganisa), sezvo zviratidzo zvichipararira pamwe chete neprobe, zvichidzivirira manzwi enhema anowanzoonekwa muradar isingabatanidzi.
2. Kuyera Kwakanaka uye Kugadzikana
- Kururama kwekuyera kunowanzo tangira pa ±0.05%FS kusvika pa ±0.1%FS, nezvikanganiso zvinodzokororwa zvakaderera se ±0.02%FS, zvichipfuura mamwe mamodheru eradar asingabatanidzwe.
- Simba rechiratidzo chekufungisisa rinonyanya kuenderana nekubatana kuripo pakati peprobe nechinhu chiri pakati, zvichiita kuti chikwanise kushandiswa nemagetsi asingachinji (semuenzaniso, peturu, gasi rakanyungudutswa).
3. Kuchinjika kuMidhiya Yakasiyana-siyana uye Nzvimbo Dzakanyanya Kuipa
- Kuenderana Kwepakati: Inokwanisa kuyera zvinwiwa (kusanganisira kusimba kwakanyanya, crystallizing media senge syrup ne caustic soda), zvidimbu zvakasimba (semuenzaniso, mapurasitiki, upfu hwemarasha), slurry (semuenzaniso, mud, muto wemichero), uye interfaces (semuenzaniso, interfaces dzemafuta nemvura).
- Kushivirira Kwezvakatipoteredza: Inotsungirira tembiricha yepamusoro (-50℃ kusvika 400℃), kumanikidzwa kwakanyanya (kusvika 40MPa), uye nzvimbo dzinopisa zvakanyanya, yakakodzera ma reactor emakemikari, matangi ekuchengetera ane kumanikidzwa kwakanyanya, nezvimwewo.
4. Kuiswa Kunochinjika Kwenzvimbo Dzakavharirwa
- Mapurobhu anogona kuiswa mumatangi madiki, midziyo isina chimiro chakasiyana, kana midziyo ine zvipingamupinyi zvemukati, zvisingade nzvimbo yakavhurika pamusoro. Anonyanya kukodzera mapurojekiti ekugadzirisa kana nzvimbo dzakamanikana.
IV. Maitiro Ekushandisa
Guided Wave Radar inoshandiswa zvakanyanya muminda inotevera nekuda kwekushanda kwayo kusingapindiri uye kunyatsoita kwayo nemazvo:
- Indasitiri yeMakemikoro: Kuyerwa kwemazinga muma reactors, matangi ekuchengetera ane simba rakawanda/rakaderera, uye kuona nzvimbo yemafuta nemvura.
- Petroleum nePetrochemical: Kuyerwa kwemazinga mumatangi emafuta asina kucheneswa, matangi emafuta akareruka (peturu, dhiziri), uye matangi ekuchengetera gasi rakanyungudutswa.
- Chikafu neChinwiwa: Kuyerwa kwemazinga mumatangi ane furo rakawanda (semuenzaniso, doro, yogati), matangi esyrup, uye slurry yemuto wemichero (ine zvinhu zvekuongorora zvekudya).
- Kurapa Mvura: Kuyera mwero mumatangi ekuchenesa tsvina yetsvina nemadziva ekunyungudutsa mvura, kudzivirira kukanganiswa kwefuro.
- Indasitiri yeSimba: Kuyerwa kwemazinga mumasilo ehupfu hwemarasha nemabhini emadota, uye kutariswa kwemazinga ebhoira rinopisa zvakanyanya.
V. Miganhu
- Zvinodiwa Pakugadzirisa Kuyera Kubatana: Maprobe anosangana zvakananga nechinhu chiri mukati, anogona kusvibiswa kana kuvharika nekuda kwekusviba, zvichida kucheneswa nguva nenguva. Zvinhu zvinokuvadza zvakanyanya zvinogona kukonzera kupera kweprobe, zvichikonzera kuti pave nezvinhu zvakakosha (zvichiwedzera mitengo).
- Range Yakaganhurirwa: Range yakanyanya kusarudzwa nehurefu hweprobe, ine mamodheru akajairwa anotangira pa 0.3m kusvika pa 30m, asina kukodzera matangi akakura zvakanyanya (radar isingabatanidzi inogona kufukidza kusvika ku 100m).
- Zvirambidzo Mukushandiswa Kwehutsanana: Muzvekudya, mishonga, nezvimwe zviitiko zvine hutsanana hwakawanda, maitiro ekuongorora kuchenesa kweprobe akaoma, zvichigona kuwedzera mari yekutevedzera mitemo (radar isina kubatana inobatsira zvikuru nekuda kwekusabatana).
- Njodzi Yekupfekwa Kweprobe: Muzviitiko zvine kuvhunduka kana kutenderera kwemhepo, machira ekudzivirira probe anofanira kuiswa kudzivirira kupwanyika kubva pakubonderana.
VI. Kusiyana Kukuru NeRadar Isina Kubata Vanhu
| Kuenzanisa | Radar yeMafungu Anotungamirirwa | Radar Isina Kubata Vanhu |
|---|---|---|
| Kupararira kweChiratidzo | Kutungamira uchitevedza probe | Kupararira kwemahara mumhepo |
| Kugona Kudzivisa Kupindira | Yakasimba (haina furo, utsi, guruva) | Kusasimba (inoda dhizaini yepamusoro-soro kana kugadzirisa antenna) |
| Kunzwisisa Dielectric Constant | Yakaderera (yakakodzera kune dielectric media yakaderera) | Yakakwirira (masaini asina simba emagetsi mashoma) |
| Kuchinjika kuZvinhu Zvinodiwa paKuchengetedza Utsanana | Zvishoma (kusimbiswa kwekuchenesa nguva nenguva) | Yakanaka kwazvo (haibatanidzwe, inoenderana nezvinodiwa neFDA/3-A) |
| Mari Yekugadzirisa | Zviri pakati nepakati (kuchenesa purobhu, kudzivirira ngura) | Yakaderera (hapana kubata, hapana kupfeka) |
| Range reKuyera Kwakanyanya | Kazhinji ≤30m | Kusvika ku100m |
Mhedziso
Guided Wave Radar isarudzo yakanaka yekuyera nhanho mumamiriro ekushanda akaomarara, kunyanya kana ichishanda zvakanaka munzvimbo dzine furo rakawanda, ine dielectric shoma, nzvimbo yakamanikana, kana nzvimbo dzakanyanya kushata. Zvisinei, hunhu hwayo hwekuyera nhanho hunounza zvinodiwa pakugadzirisa uye zvipingamupinyi zvekushandisa. Mukusarudza kwakakodzera, zvinhu zvakaita sehunhu hwepakati (kusviba, kuora, dielectric constant), mamiriro ekunze (tembiricha, kumanikidzwa, nzvimbo), uye zvinodiwa zvehutsanana zvinofanirwa kuongororwa zvakakwana. Kana zvichidikanwa, inogona kushandiswa pamwe chete neradar isingashande kuti ifukidze mamiriro akawanda.
