Iintsilelo zangoku ze-flowmeter ye-ultrasonic ubukhulu becala kukuba uluhlu lweqondo lokushisa lomzimba wokuhamba olulinganisiweyo lukhawulelwe ngokumelana nobushushu be-aluminium yokutshintshiselana kwamandla e-ultrasonic kunye nezinto zokudibanisa phakathi kwe-transducer kunye nombhobho, kunye nedatha yokuqala yesantya sokudlulisa isandi. womzimba wokuqukuqela olinganisiweyo kumaqondo obushushu aphezulu awuphelelanga.Okwangoku, i-China ingasetyenziselwa kuphela ukulinganisa ulwelo olungaphantsi kwe-200 ℃.Ukongezelela, umgca wokulinganisa we-ultrasonic flowmeter unzima ngakumbi kune-flowmeter jikelele.Oku kungenxa yokuba isantya sokuhamba kolwelo kwimitha yemizi-mveliso idla ngokuba ziimitha ezimbalwa ngomzuzwana, kwaye isantya sosasazo lwezandi zamaza kulwelo simalunga ne-1500m/s, kunye notshintsho kwisantya sesandi esiziswa lutshintsho. kwisantya sokuhamba somzimba olinganisiweyo wokuqukuqela kwakhona 10-3 imiyalelo yobukhulu.Ukuba ukuchaneka komlinganiselo wokuhamba komlinganiselo kufuneka kube yi-1%, ukuchaneka komlinganiselo wesantya sesandi kufuneka kube yi-10-5 ~ 10-6 imiyalelo yobukhulu, ngoko ke kufuneka kubekho umgca wokulinganisa ogqibeleleyo ukuze kuphunyezwe, kwakhona. i-flowmeter ye-ultrasonic ingaba yinkqubo esebenzayo kuphela phantsi kophuhliso olukhawulezayo lweteknoloji yesekethe edibeneyo.
(1) Uluhlu lomlinganiselo wobushushu be-flowmeter ye-ultrasonic alukho phezulu, kwaye ngokubanzi lunokulinganisa kuphela ulwelo olunobushushu obungaphantsi kwe-200 ° C.
(2) Ukungakwazi ukuchasana nokuphazanyiswa.Kulula ukuphazamiseka ingxolo ye-ultrasonic exutywe kunye namaqamza, ukulinganisa, iimpompo kunye neminye imithombo yesandi kwaye ichaphazela ukuchaneka komlinganiselo.
(3) Icandelo lombhobho elithe tye lifuneka ngokungqongqo kwi-20D yokuqala kunye ne-5D yokugqibela.Ngaphandle koko, ukusasazwa kubi kwaye ukuchaneka komlinganiselo kuphantsi.
(4) Ukungaqiniseki kofakelo kuya kuzisa impazamo enkulu kumlinganiselo wokuhamba.
(5) Ukukaliswa kombhobho wokulinganisa kuya kuchaphazela ngokunzulu ukuchaneka komlinganiselo, okukhokelela kwiimpazamo ezibalulekileyo zokulinganisa, kwaye kungabikho mboniso wokuhamba kwiimeko ezinzima.
(6) Ukuthembeka kunye nenqanaba lokuchaneka alikho phezulu (ngokubanzi malunga ne-1.5 ~ 2.5), kwaye ukuphindaphinda kubi.
(7) Ubomi obufutshane benkonzo (ukuchaneka ngokubanzi kunokuqinisekiswa kuphela unyaka omnye).
(8) I-Ultrasonic flowmeter ngokulinganisa isantya se-fluid ukugqiba umthamo womthamo, ulwelo kufuneka lulinganise ukuhamba kwayo kobuninzi, umlinganiselo wesixhobo sokuhamba kobuninzi ufunyanwa ngokuphindaphinda ukuhamba kwevolumu ngokuxinaniswa okwenziwe ngokwenziwa, xa ubushushu bamanzi buguquka, Uxinaniso lwe-fluid lutshintshile, ixabiso le-artificially set density value, alinakuqinisekisa ukuchaneka kokuhamba kobuninzi.Kuphela xa isantya solwelo silinganiswa ngexesha elinye, ukuxinana kolwelo kuyalinganiswa, kwaye ubungakanani bokwenene bokuhamba kobunzima bunokufunyanwa ngokubala.
(9) Ukuchaneka komlinganiselo we-Doppler ayikho phezulu.Indlela ye-Doppler ilungele ulwelo lwe-biphase kunye nomxholo ongekho phezulu kakhulu, njengogutyulo olungacocwanga, ulwelo lokukhupha kwifektri, ulwelo olumdaka lwenkqubo;Ayiqhelekanga ulwelo olucocekileyo kakhulu.
