Q, ngati pali thovu mu payipi, kodi muyeso wa flowmeter wa ultrasonic ndi wolondola?
A: Ngati pali thovu mu payipi, ngati thovulo likukhudza kuchepa kwa chizindikiro, zidzakhudza kulondola kwa muyeso.
Yankho: Choyamba chotsani thovu kenako muyeso.
Q: Choyezera kuyenda kwa ma ultrasound sichingagwiritsidwe ntchito m'munda wa kusokoneza kwamphamvu?
A: Kusinthasintha kwa magetsi ndi kwakukulu, pali chosinthira ma frequency kapena kusokoneza kwamphamvu kwa maginito, ndipo mzere wapansi siwolondola.
Yankho: Kuti pakhale magetsi okhazikika a ultrasound flowmeter, kuyika flowmeter kutali ndi frequency converter ndi kusokoneza kwamphamvu kwa maginito, pali mzere wabwino wa nthaka.
Q: Masensa olumikizira a ultrasound patatha nthawi yochepa chizindikiro chikachepa?
A: Sensa yolumikizira ya ultrasonic ikhoza kukhala yosiyana kapena kukula kwa pamwamba pa sensa ndi kokhuthala.
Yankho: Sinthani malo a sensa yolowetsedwa ndi ultrasound ndikuyeretsa pamwamba pa sensa yotumizira.
Q: Chizindikiro cha flowmeter chakunja kwa ultrasound chili chochepa?
Yankho: M'mimba mwake wa chitoliro ndi waukulu kwambiri, sikelo ya chitoliro ndi yayikulu, kapena njira yoyikira si yolondola.
Yankho: Ngati m'mimba mwake wa chitoliro ndi waukulu kwambiri, kukula kwake kwakukulu, tikukulimbikitsani kugwiritsa ntchito sensa yolowetsedwa ndi ultrasound, kapena kusankha kukhazikitsa kwa mtundu wa "Z".
Q: Kodi kusintha kwa kayendedwe ka madzi nthawi yomweyo kwa ultrasound flowmeter ndi kwakukulu?
A. Mphamvu ya chizindikiro imasintha kwambiri; B, kusinthasintha kwa madzi oyezera;
Yankho: Sinthani malo a sensa ya ultrasonic, onjezerani mphamvu ya chizindikiro, ndikuwonetsetsa kuti mphamvu ya chizindikiroyo ndi yokhazikika. Ngati kusintha kwa madzi kuli kwakukulu, malo ake si abwino, ndikusankhanso malowo kuti muwonetsetse kuti zofunikira pakugwira ntchito kwa 5D pambuyo pa *D ndi zomwe zili.
Q: Chiŵerengero cha nthawi yotumizira ma ultrasound flowmeter yochepera 100%±3, chifukwa chake ndi chiyani, momwe mungasinthire?
A: Kukhazikitsa kosayenera, kapena magawo olakwika a mapaipi, kuti mudziwe ngati magawo a mapaipi ndi olondola, mtunda wokhazikitsa ndi wolondola
Q: Choyezera kuyenda kwa ma ultrasound sichingathe kuzindikira chizindikiro?
A: Tsimikizirani ngati magawo a mapaipi akhazikitsidwa bwino, ngati njira yoyikira ndi yolondola, ngati mzere wolumikizira uli bwino, ngati payipiyo yadzazidwa ndi madzi, ngati njira yoyezera ili ndi thovu, ngati sensa ya ultrasonic yayikidwa malinga ndi mtunda woyikira womwe wawonetsedwa ndi wolandila wa ultrasonic flowmeter, komanso ngati njira yoyikira sensayo ndi yolakwika.
Q: Choyezera kuyenda kwa madzi cha Ultrasonic Q value imafika pansi pa 60, chifukwa chake ndi chiyani? Kodi mungasinthe bwanji?
A: Ngati palibe vuto ndi kukhazikitsa m'munda, mtengo wotsika wa Q ukhoza kuyambitsidwa ndi madzi omwe ali mu payipi yomwe ikuyesedwa, kupezeka kwa thovu, kapena kupezeka kwa zida zosinthira ma frequency ndi kuthamanga kwambiri m'malo ogwirira ntchito ozungulira.
1) Onetsetsani kuti madzi omwe ali mu payipi yomwe ikuyesedwa ndi odzaza ndipo palibe thovu (ikani valavu yotulutsira utsi);
2) Onetsetsani kuti choyezera ndi choyezera cha ultrasound zili pansi bwino;
3) Mphamvu yogwirira ntchito ya ultrasound flowmeter siyenera kugawana mphamvu ndi zida zosinthira ma frequency ndi ma voltage ambiri, ndipo yesetsani kugwiritsa ntchito mphamvu ya DC kuti igwire ntchito;
4) Mzere wa chizindikiro cha sensa ya ultrasonic suyenera kufanana ndi chingwe chamagetsi, ndipo uyenera kufanana ndi chingwe cha chizindikiro cha flow meter kapena mzere wosiyana ndi chubu chachitsulo kuti chiteteze chishango;
5) Sungani makina oyezera kuyenda kwa madzi a ultrasonic kutali ndi malo osokonezera;
Q, njira zodzitetezera pakuyika chingwe cha flowmeter cha ultrasonic?
1. Mukayika chubu cha chingwe cha ultrasonic flowmeter, yesani kuyika chingwe chamagetsi ndi mzere wa chizindikiro padera, musagwiritse ntchito chitoliro chomwecho, sankhani chitoliro cha galvanized cha mfundo 4 (1/2 “) kapena mfundo 6 (3/4 “), chomwe chingakhale chofanana.
2, mukayika pansi pa nthaka, ndi bwino kuti chingwecho chikhale ndi chubu chachitsulo kuti chingwecho chisagwedezeke kapena kulumidwa ndi makoswe, m'mimba mwake wakunja wa chingwecho ndi 9 mm, awiriawiri a sensa ya ultrasonic ndi zingwe ziwiri, m'mimba mwake wamkati wa chubu chachitsulocho uyenera kukhala woposa 30 mm.
3, kuti zichotsedwe pa chingwe chamagetsi, ndi zingwe zina zomwe zimayika ngalande yomweyo ya chingwe, ziyenera kuvala mapaipi achitsulo kuti ziwongolere magwiridwe antchito oletsa kusokonezedwa.
Choyezera madzi chakunja cholumikizidwa ndi ultrasonic ndi mtundu wa choyezera madzi choyenera kwambiri kuyeza chitoliro chonse, chosavuta kuyika komanso chosakhudzana, zonse ziwiri zimatha kuyeza madzi apakati a m'mimba mwake waukulu wa chitoliro zingagwiritsidwenso ntchito poyeza madzi omwe si osavuta kuwakhudza ndi kuwaona, kulondola kwake kwa muyeso ndi kwakukulu kwambiri, pafupifupi kopanda kusokonezedwa ndi magawo osiyanasiyana a choyezera madzi. Makamaka, imatha kuthetsa mavuto oyezera madzi omwe amawononga kwambiri, osayendetsa magetsi, owononga ma radiation, komanso oyaka moto komanso ophulika omwe zida zina sizingathe. Chifukwa chakuti ili ndi mitundu ina ya zida zomwe zili pamwambapa sizili ndi makhalidwe ake, yakhala ikugwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana amadzi am'madzi am'madzi, zimbudzi, madzi am'nyanja ndi zina zamadzimadzi, komanso imagwiritsidwanso ntchito mu mafuta, mankhwala, zitsulo ndi zina.
Choyezera madzi chakunja chotchedwa clamp ultrasonic flowmeter nthawi zambiri chimagwira ntchito bwino kwa nthawi yayitali chikayikidwa popanda kukonza, ndipo sikofunikira kudabwa ngati vuto losalandira chizindikiro kapena chizindikiro chofooka kwambiri litachitika, bola ngati mukuyenera kupereka malangizo asanu malinga ndi ukadaulo wa zida za Xiyuan, ntchito yokhazikika komanso chithandizo chosamala zidzabwerera mwachangu kuchizolowezi:
1. Choyamba tsimikizirani ngati choyezera madzi chomwe chili mu payipi chili chodzaza ndi madzi;
2. Ngati chitoliro chili pafupi kwambiri ndi khoma, chofufuzira chingathe kuyikidwa pa m'mimba mwake wa chitoliro ndi ngodya yopendekera, m'malo moyika pa m'mimba mwake wa chitoliro chopingasa, njira ya Z iyenera kugwiritsidwa ntchito poyika chofufuziracho;
3. Sankhani mosamala gawo lokhuthala la payipi ndikulipukuta bwino, ikani mizu ya lotus yokwanira kuti muyike probe;
4. Sungani mosamala chofufuzira chilichonse pang'onopang'ono pafupi ndi malo oikira kuti mupeze malo oikira chizindikiro chachikulu kuti mupewe malo oikira chizindikiro omwe angalandire chizindikiro champhamvu kuti asaphonyedwe chifukwa cha kukula kwa khoma lamkati la payipi kapena chifukwa cha kusintha kwa payipi komwe kumapangitsa kuti kuwala kwa ultrasound kuwonetse malo omwe akuyembekezeka;
5. Pa mapaipi achitsulo okhala ndi ma scaling akuluakulu pakhoma lamkati, njira yogunda ingagwiritsidwe ntchito kuti gawo la ma scaling ligwe kapena kusweka, koma ziyenera kudziwika kuti njira iyi nthawi zina sithandiza kutumiza mafunde a ultrasound chifukwa cha kusiyana pakati pa ma scaling ndi khoma lamkati.
Popeza flowmeter yakunja yolumikizidwa ndi ultrasound imagwiritsidwa ntchito kwambiri poyesa madzi odetsedwa, ikatha kugwira ntchito kwa nthawi yayitali, nthawi zambiri imasonkhanitsa guluu pakhoma lamkati la sensa ndipo imayambitsa kulephera. Ndikofunikira kuti chipangizo chosefera chiyikidwe pamwamba ngati pali zinthu zina, zomwe zingathandize kuti chidacho chikhale chokhazikika komanso kuti deta yoyezera ikhale yokhazikika.
