Q, uma kunamabhamuza epayipini, ingabe isilinganiso se-flowmeter ye-ultrasonic sinembile?
IMP: Uma kukhona amabhamuza epayipini, uma amabhamuza ethinta ukwehla kwesignali, kuzothinta ukunemba kwesilinganiso.
Isixazululo: Qala ngokukhipha ibhamuza bese ukala.
Q: I-Flowmeter ye-Ultrasonic ayikwazi ukusetshenziswa emkhakheni wokuphazanyiswa okuqinile?
A: Ububanzi bokuguquguquka kokunikezwa kwamandla bukhulu, kukhona isiguquli semvamisa noma ukuphazamiseka okunamandla kazibuthe okuzungezile, futhi umugqa ophansi awulungile.
Isixazululo: Ukuhlinzeka ngogesi ozinzile we-flowmeter ye-ultrasonic, ukufakwa kwe-flowmeter kude ne-converter ye-frequency kanye nokuphazamiseka okunamandla kazibuthe, kukhona umugqa omuhle wokumisa.
Q: Izinzwa ze-plug-in ze-Ultrasonic ngemva kwesikhathi esithile ngemva kokunciphisa isignali?
A: Inzwa ye-plug-in ye-ultrasonic ingase isuswe noma isikali sobuso benzwa siwugqinsi.
Isixazululo: lungisa indawo yenzwa efakwe i-ultrasonic bese usula indawo yokudlulisa yenzwa.
Q: I-ultrasonic ngaphandle kwesignali ye-clamp flowmeter iphansi?
Impendulo: Ububanzi bepayipi bukhulu kakhulu, isikali sepayipi sibucayi, noma indlela yokufaka ayilungile.
Isixazululo: Ngoba ububanzi bepayipi bukhulu kakhulu, ukukala okukhulu, kunconywa ukusebenzisa inzwa efakwe nge-ultrasonic, noma ukhethe ukufakwa kohlobo lwe-"Z".
Q: Ingabe ukuguquguquka kokugeleza okusheshayo kwe-flowmeter ye-ultrasonic kukhulu?
A. Amandla esignali ashintshashintsha kakhulu;B, ukuguquguquka koketshezi lwesilinganiso;
Isixazululo: Lungisa indawo yenzwa ye-ultrasonic, uthuthukise amandla esignali, futhi uqinisekise ukuqina kwamandla esignali.Uma ukushintshashintsha koketshezi kukukhulu, indawo ayilungile, bese ukhetha kabusha iphoyinti ukuze uqinisekise izidingo zesimo sokusebenza se-5D ngemva *D.
Q: Ultrasonic flowmeter yokulinganisa isikhathi sokudlulisa isilinganiso esingaphansi kwe-100% ± 3, siyini isizathu, indlela yokuthuthukisa?
A: Ukufakwa okungalungile, noma amapharamitha wepayipi angalungile, ukuthola ukuthi imingcele yepayipi inembile, ibanga lokufaka lilungile.
Q: I-Flowmeter ye-Ultrasonic ayikwazi ukubona isignali?
A: Qinisekisa ukuthi amapharamitha wepayipi amiswe ngendlela efanele, noma indlela yokufaka ilungile, noma ngabe ulayini wokuxhuma uxhumeke kahle, noma ngabe ipayipi ligcwele uketshezi, noma ngabe into elinganisiwe inamabhamuza, noma ngabe inzwa ye-ultrasonic ifakiwe ngokuya ibanga lokufaka elikhonjiswe umsingathi we-flowmeter we-ultrasonic, nokuthi isiqondiso sokufakwa kwenzwa akulungile yini.
Q: Ultrasonic flowmeter Q value ifinyelela ngaphansi kuka-60, iyini imbangela?Indlela yokuthuthukisa?
IMP: Uma kungekho nkinga ngokufakwa endle, inani eliphansi le-Q lingase libangelwe uketshezi olusepayipini elihlolwayo, ukuba khona kwamabhamuza, noma ukuba khona kokuguqulwa kwemvamisa kanye nemishini yokucindezela okukhulu ezimeni zokusebenza ezizungezile. .
1) Qinisekisa ukuthi uketshezi olusepayipini elihlolwayo lugcwele futhi alikho ibhamuza (faka ivalvu yokukhipha umoya);
2) Qinisekisa ukuthi umgcini wokulinganisa kanye nenzwa ye-ultrasonic zisekelwe kahle;
3) Ukunikezwa kwamandla okusebenzayo kwe-flowmeter ye-ultrasonic akufanele kuhlanganyele ukunikezwa kwamandla ngokuguqulwa kwemvamisa kanye nemishini ye-voltage ephezulu, bese uzama ukusebenzisa amandla kagesi e-DC ukuze usebenze;
4) Ulayini wesignali yenzwa ye-ultrasonic akufanele uhambisane nekhebula lamandla, futhi kufanele uhambisane nekhebula lesignali yemitha yokugeleza noma umugqa ohlukile kanye neshubhu lensimbi ukuvikela isihlangu;
5) Gcina umshini we-flowmeter we-ultrasonic kude nemvelo yokuphazamiseka;
Q, ultrasonic flowmeter ikhebula laying izinyathelo?
1. Lapho ubeka ishubhu yekhebula ye-Flowmeter ye-ultrasonic, zama ukubeka intambo yamandla nolayini wesignali ngokuhlukana, ungasebenzisi ipayipi elifanayo, khetha amaphuzu angu-4 (1/2 “) noma amaphuzu angu-6 (3/4”) ipayipi elinothayela, okuyinto kungaba parallel.
2, lapho ubeka ngaphansi komhlaba, kunconywa ukuthi ikhebula ligqoke ishubhu lensimbi ukuvimbela ikhebula ukuthi lingagingqiki noma lilunywe amagundane, ububanzi bangaphandle bekhebula bungu-9 mm, ipheya ngalinye lezintambo ezi-2 zenzwa ye-ultrasonic, ububanzi obungaphakathi ithubhu lensimbi kufanele libe likhulu kunama-30 mm.
I-3, ukuze ihlukaniswe nentambo kagesi, nezinye izintambo ezibeka umsele wekhebula ofanayo, zidinga ukugqoka amapayipi ensimbi ukuze kuthuthukiswe ukusebenza kokulwa nokuphazamiseka.
I-flowmeter ye-ultrasonic clamped yangaphandle iwuhlobo lwemitha yokugeleza olufaneleka kakhulu ukulinganisa ipayipi eligcwele, ngokufaka kalula futhi okungathinteki, kokubili kungakala ukugeleza okuphakathi kobubanzi bepayipi elikhulu kungasetshenziswa futhi ukulinganisa okuphakathi okungelula ukuthintana futhi. bheka, ukunemba kwesilinganiso sayo kuphezulu kakhulu, cishe akunakuphazamiseka kwemingcele ehlukahlukene yendlela elinganisiwe.Ikakhulukazi, ingakwazi ukuxazulula izinkinga zokulinganisa ukugeleza kwemidiya egqwala kakhulu, engaphenduki, ekhipha imisebe, evuthayo futhi eqhumayo ezinye izisetshenziswa ezingakwazi.Ngenxa yokuthi inezinye izinhlobo zamathuluzi ezingenhla azinazo izici, isetshenziswe kabanzi ezimbonini zamanzi kampompi ahlukahlukene, indle, amanzi olwandle nezinye izilinganiso zoketshezi, kodwa futhi isetshenziswa ku-petroleum, amakhemikhali, i-metallurgy nakweminye imikhakha.
I-flowmeter ye-ultrasonic yohlobo lwe-clamp yangaphandle ingasebenza ngokujwayelekile isikhathi eside ngemuva kokufakwa ngaphandle kokulungiswa, futhi akudingekile ukumangala uma kwenzeka inkinga yokungatholi isignali noma isignali ebuthakathaka kakhulu, inqobo nje uma kufanele uncome izinyathelo ezinhlanu. ngokobuchwepheshe bensimbi ye-Xiyuan, ukusebenza okujwayelekile kanye nokwelashwa ngokucophelela kuzobuyela ngokushesha kokujwayelekile:
1. Okokuqala qinisekisa ukuthi i-flowmeter ekwipayipi igcwele uketshezi;
2. Uma ipayipi isondele kakhulu odongeni, i-probe ingafakwa kububanzi bepayipi nge-Angle ethambekele, kunokuba kububanzi bepayipi evundlile, indlela ye-Z kufanele isetshenziselwe ukufaka i-probe;
3. Khetha ngokucophelela ingxenye eminyene yepayipi bese uyipholisha ngokugcwele, sebenzisa ingxube eyanele yempande ye-lotus ukuze ufake uphenyo;
4. Hambisa i-probe ngayinye kancane kancane eduze kwendawo yokufaka ukuze uthole iphoyinti lesignali elikhudlwana ukuvimbela indawo yokufaka engathola isignali enamandla ukuthi ingagejwa ngenxa yokukalwa odongeni lwangaphakathi lwepayipi noma ngenxa yokuguquguquka kwendawo kwepayipi elikhona. kubangela ugongolo lwe-ultrasonic lubonise indawo elindelekile;
5. Ngamapayipi ensimbi anesilinganiso esibucayi odongeni lwangaphakathi, indlela yokushaya ingasetshenziswa ukwenza ingxenye yokukala iwe noma iqhekeke, kodwa kufanele kuqashelwe ukuthi le ndlela ngezinye izikhathi ayisizi ukuhanjiswa kwamagagasi e-ultrasonic ngenxa igebe phakathi kokukala nodonga lwangaphakathi.
Ngenxa yokuthi i-flowmeter ye-ultrasonic eboshiwe yangaphandle ivame ukusetshenziselwa ukukala uketshezi olungcolile, ngemva kokusebenza isikhathi esithile, ivame ukuqoqa ungqimba olunamathelayo odongeni lwangaphakathi lwenzwa futhi ibangele ukwehluleka.Kunconywa ukuthi idivayisi yokuhlunga ingafakwa endaweni engenhla uma kunezimo, okuzodlala kangcono ukuzinza kwensimbi futhi kugcine ukuqina kwedatha yokulinganisa.
