Yintoni ekufuneka ithathelwe ingqalelo xa ufaka i-double-channel ultrasonic flow meter?

Ukusetyenziswa kweIimitha ezimbini ze-ultrasonic channelizinzile ngakumbi kuneemitha ze-mono ultrasonic. Ngoku uninzi lwezicelo zeemitha eziphindwe kabini ze-ultrasonic zikwindawo. Ngoko ke zeziphi iingxaki ekufuneka zinikwe ingqwalasela ngexesha lenkqubo yofakelo iyonke?

1. Zama ukucoca umbhobho phambi kokufaka imitha yokuqukuqela ye-ultrasonic chaneli-mbini ukunqanda ubutyobo ekubeni bonakalise imitha yokuhamba komoya;
2. I-double-channel ultrasonic flow meter yeyesixhobo esixabiseke ngakumbi. Zama ukuqaphela xa uyiphakamisa kwaye ufunde ukuyibeka phantsi. Kuvinjelwe ngokungqongqo ukuphakamisa intloko yemitha kunye nekhebula lenzwa;
3. Akuvunyelwe ukusondela kwi-pyrogens ephezulu yokushisa njenge-welding yombane, ukuphepha ukuqhuma kwebhetri, ukulimala kunye nokulimala kwesixhobo;
4. Kufuneka kuqwalaselwe indawo yofakelo lwemitha yokuqukuqela ye-ultrasonic ye-double channel. Isilinganisi-manzi sokuhamba komphunga kufuneka sithintelwe ekubeni sifakwe ngaphezulu kombhobho (iqamza liza kuvela kumbhobho), kwaye akufuneki ukuba lifakwe kufutshane nengqiniba (nto leyo eya kubangela ukuhamba kwevortex). Ukuphelisa iimpompo kunye nabanye oomatshini kunye nezixhobo (eziya kubangela ukugeleza kwesiselo esiphuphumayo); Imibhobho edibanisayo entla, ezantsi naphakathi nasezantsi kwe-ultrasonic flow meter kufuneka ihambelane nobukhulu be-caliber ye-steam flow meter, kwaye i-diameter ayinakuncitshiswa;
5.Isalathiso esibonakaliswe lutolo oluphezulu kumphezulu we-double-channel ultrasonic flow meter yindlela yamanzi aqukuqelayo, engenakuguqulwa;
6. Ukuze kuqinisekiswe ngcono ukuchaneka kokuqinisekiswa komlinganiselo, ukufakwa kweimitha yokuqukuqela ye-ultrasonic yamatshaneli amabinikufuneka imbele ngaphambili umgama othile wecandelo lokudibanisa. Ngokuqhelekileyo, amaxesha angama-10 ubude bombhobho ubude obufunekayo phambi komitha, kunye namaxesha ama-5 umbhobho emva komitha. Icandelo lokuthatha elinobubanzi obufutshane;
7. Kucetywa ukuba umphambili wesiphelo se-double-channel ultrasonic flow meter kufuneka sixhotyiswe ngesixhobo sokuhluza esikwizinga eliphezulu; Umphambili wemitha uxhotyiswe ngevalve yesango lokulinganisa kwaye inokwahlulwa ukusuka kumphezulu, ohambelana nokugcinwa nokulungiswa kwexesha elizayo;
8. Jonga imeko yangoku kangangoko kunokwenzeka phambi kokurekhoda izinga lokuhamba kwe-ultrasonic channel-two;
