Mamiriro epamusoro pepombi anokanganisa zvakananga mashandiro e clamp-on ultrasonic flow meter, sezvo mamita aya achitsamira pa acoustic signal transmission pakati pe transducers dzakaiswa kunze kwepombi. Chero kusarongeka, kusvibiswa, kana kuputirwa pamusoro pepombi kunogona kukanganisa nzira yemafungu e ultrasonic, zvichikonzera kudzikira kwekururama, kusagadzikana kwechiratidzo, kana kutotadza kuyerwa. Pazasi pane kupatsanurwa kwakadzama kwekuti mamiriro chaiwo epamusoro anokanganisa sei mashandiro:
1. Kuomarara Kwepamusoro uye Kusarongeka
Mamita eClamp-on anoshandisa ma ultrasonic transducers anoburitsa uye anogamuchira mafungu eruzha kuburikidza nemadziro epombi. Nzvimbo isina kuenzana kana isina kuenzana inokanganisa maitiro aya nenzira dzakasiyana-siyana:
- Kupararira kwezviratidzo: Nzvimbo dzakakombama (semuenzaniso, kukwenya kwakadzika, mabhora esimbi, kana kuti maburi) dzinoparadzira mafungu eultrasonic, zvichiabvisa kubva kune anogamuchira. Izvi zvinoderedza simba rezviratidzo, zvichideredza kunyatsojeka kwekuyera.
- Kukundikana kweAcoustic Coupling: Matransducer anoshandisa coupling gel (chinhu chakamanikana) kuti agadzire chisungo chisina musono pakati petransducer nepombi. Nzvimbo isina kusimba inobata mabubble emhepo mugel, ichishanda sezvipingamupinyi zvinovhara kana kuratidza mafungu eruzha. Izvi zvinotungamira mukurasikirwa kwechiratidzo kana kuverenga nguva nenguva.
- Kureba Kwenzira Kusingaenderane: Kusarongeka kwakanyanya (semuenzaniso, kutsemuka kana kubuda) kunochinja daro riri pakati pematransducers nemvura, zvichikanganisa kureba kwenzira ye ultrasonic kwakaverengerwa. Izvi zvinounza zvikanganiso mukuverenga kumhanya kwekuyerera.
2. Ngura, Chikero, kana Ngura
Ngura gobvu, chikero chemineral, kana ngura pamapombi esimbi zvinokanganisa mashandiro epombi:
- Kudzikira kweAcoustic: Ngura nehukuru zvinhu zvine maburi kana kuti zvakawandisa zvinotora simba re ultrasonic, zvichideredza amplitude yesignal inosvika kune inogamuchira. Muzviitiko zvakanyanya, chiratidzo chinogona kunge chisina kusimba zvekusagona kuonekwa, zvichiita kuti mita ikundikane.
- Kutapurirana kweChiratidzo Chisina Kuenzana: Kuora kunowanzoita kuti pave nemaumbirwo asina kuenzana pamusoro (semuenzaniso, ngura yakapwanyika kana simbi ine makomba), zvichikonzera kupararira kwemafungu asingaenderane. Izvi zvinoguma nekusiyana-siyana kwekuverenga kana kudzikira kwekururama.
- Matambudziko Ekubatanidza: Zvidimbu zvengura zvisina kusimba zvinogona kusanganiswa nejeli rekubatanidza, zvichigadzira grit wave wakaoma inodzivirira kusangana kwakakodzera pakati pe transducer nepombi.
3. Kupenda, Pendi, kana Kuisa Zvinhu Zvakachengetwa
Mapaipi ane machira (pendi, tara, epoxy) kana madhayi (mafuta, tsvina) anokanganisa mashandiro zvichienderana nekukora kwawo uye kufanana kwawo:
- Mapendi Akakora Kana Akaoma: Mapendi akakora kupfuura 1–2 mm anoshanda seacoustic insulators, achideredza mafungu e ultrasonic. Mapendi akaomarara, anopwanyika (semuenzaniso, pendi yekare ine mitswe) anogona kuratidza mafungu panzvimbo pekuatumira, zvichikonzera kurasikirwa kwechiratidzo.
- Mapendi Asina Kuenzana: Mapendi asina kuenzana kana kuti madhaidhi asina kuenzana anoita kuti pave nenzira dzisingawirirane dzeacoustic. Semuenzaniso, ganda gobvu rependi riri pasi pe transducer imwe asi kwete rimwe rinokanganisa kuenzana kwechiratidzo, zvichiita kuti pave nekukanganisa pakuyera.
- Zvinhu zvakapfava kana kuti zvine maburi: Zvinhu zvakaita setara, wakisi, kana tsvina zvinogona kupinza simba re ultrasonic kana kubata mhepo, zvichiwedzera kushayisa simba chiratidzo.
4. Zvinhu zvepombi uye kuoma kwenzvimbo
Kunyange zvazvo isiri "mamiriro" ega ega, zvinhu zvepombi nekuoma kwenzvimbo zvinopindirana nekusarongeka kwenzvimbo:
- Zvinhu Zvakapfava (semuenzaniso, PVC, mhangura): Kukwenya kana kupwanyika mumapaipi akapfava kunogona kukonzera migero yakadzika, isina kurongeka inovhara mhepo mujeli yekubatanidza. Kupukuta zvinyoro-nyoro kunowanzodiwa kuti zvikanganiso izvi zvigadzikane.
- Zvinhu Zvakaoma (semuenzaniso, simbi, simbi yakakandwa): Nzvimbo dzakaoma hadzina kuchinjika zvakanyanya asi dzinogona kuita ngura yakapinza, yakaoma kana kuti makwande anoparadzira zviratidzo. Kukweshana kwechiedza (semuenzaniso, kukwesha waya) kunoshanda pano.
- Kupedzisa Kwakatsetseka vs. Kugadzirisa Magadzirirwo: Mapaipi akatsetseka akagadzirwa nefekitori (semuenzaniso, simbi isingatsvedzeri, HDPE) anowanzo shanda zvakanaka, sezvo nzvimbo dzawo dzakafanana dzichiita kuti masaini aenderane. Kupedzisa kwakagadzirwa kana kuti kusina kutsvedza (semuenzaniso, PVC isina kutsvedza) kungada kucheneswa zvishoma asi hazvidi kuporishwa.
5. Kubudirira pakuyera zvakarurama uye kuvimbika
Mamiriro asina kunaka epamusoro anoonekwa mumatambudziko ekushanda anoyerwa:
- Kuderedzwa Kwekurongeka: Kukanganiswa kwechiratidzo kunotungamira mukukanganisa mukumhanya kwekuyerera, vhoriyamu, kana kuverenga huremu (kazhinji ± 5% kana kupfuura, zvichienzaniswa ne ± 1–2% yemapombi ane mamiriro akanaka).
- Kudonha kweSignali: Kusasimba kweSignali kunogona kukonzera kuti mita ichinje kuita "hold" mode kana kuratidza kuverenga kusina kunaka, zvichikanganisa kunyorwa kwedata kana kudzora mashandiro.
- Kugadziriswa Kwakawedzerwa: Kusagadzikana kwemasaini nguva nenguva kungada kuti ma transducer agadziriswe patsva, kushandisa gel yekubatanidza, kana kuchenesa kakawanda, zvichiwedzera mari yekushandisa.
Mamiriro epamusoro pepombi anokanganisa zvakananga kushanda zvakanaka kwekubatanidza masaini uye kusimba kwezviratidzo zvema clamp-on ultrasonic flow meter. Nzvimbo dzakapfava, dzakachena, uye dzakaputirwa zvakaenzana dzinovimbisa kutapurirana kwechiratidzo kwakakodzera, kuchengetedza kururama uye kuvimbika. Kusiyana neizvi, nzvimbo dzakaoma, dzine ngura, kana dzisina kuenzana dzinoparadzira kana kupinza mafungu e ultrasonic, zvichikonzera zvikanganiso zvekuyera, kurasikirwa nechiratidzo, kana kuwedzera kugadziriswa. Kunyange zvazvo kupolisha kusingadiwi nguva dzose, kugadzirira nzvimbo yakanangwa (semuenzaniso, kubvisa ngura, kutsvedzerera) munzvimbo dzakakosha dzekuisa kunogona kuwedzera kushanda zvakanaka.
