Umhlahlandlela Wokuhlola Ukushisa Okuphezulu Kwezinga lokushisa le-Vortex Flowmeters
I-steam yezinga lokushisa eliphezulu ngaphezu kuka-300°C ingalimaza kalula ama-vortex flowmeters noma ibangele ukwehluleka okuyingozi uma ihlolwe ngendlela engafanele. Lo mhlahlandlela wokuphepha usiza ukugwema amaphutha edatha, ukutubeka kwezinsimbi, kanye nezingozi zokuphepha.
1. Ngaphambi Kokuhlola Ukuphepha Nokulungiselela
Ngaphambi kokuhlola, nciphisa ingcindezi yamapayipi nezinga lokushisa libe amazinga aphephile, futhi gqoka amagilavu angangeni ekushiseni kanye nesivikelo sobuso.
Umthetho obalulekile wokwahlukanisa: UNGAKUSASI ukuvala amapayipi, kodwa gcina okungenani uhhafu wenduku yesandiso senzwa obala ukuze uphole. Ukuvala isidlulisi ku-insulation kuzoshisa kakhulu futhi kucekele phansi izinto zikagesi.
2. Ukufakwa kanye Nezimfuneko Zepayipi Eliqondile
Ukugeleza okungazinzile okuvela ezindololwaneni noma kumavalvu kubangela ukuphazamiseka okukhulu kwesignali.
- Ipayipi eliqondile elikhuphukayo:15D–20D(ngaphezu kuka-40D uma amavalvu okulawula eseduze)
- Ipayipi eliqondile eliya phansi:≥5DUkufundwa okungaqondakali ngokuvamile kubangelwa ukufakwa okungalungile, hhayi imitha ngokwayo.
3. Ukusetha Ipharamitha: Okugcweleyo ngokumelene ne-Superheated Steam
Ukuhlanganisa izinhlobo zesitimu kuyimbangela enkulu yedatha engavumelekile.
- Umusi oshisa kakhulu: Idinga kokubili isinxephezelo sezinga lokushisa nengcindezi.
- Isitimu esigcwele: Idinga okungenani ipharamitha yesinxephezelo esisodwa.Ukufakwa okungalungile kungase kuguqule isitimu esigcwele sibe isitimu esimanzi, okuholela emiphumeleni enganembile kakhulu uma ingalungiswa. Qinisekisa ukuthi i-RTD ilungile kanye nokubekwa kwe-pressure transmitter.
4. Ukuhlolwa Kwesiginali: Hlola Ama-Waveform, Hhayi Ukufunda Kuphela
Sebenzisa i-oscilloscope ukuze uhlole izimpawu ze-pulse ezihlanzekile. Umsindo owedlulele uvamise ukuvela ekudlidlizeni kwamapayipi. Faka okokufaka namaphedi amelana nokudlidliza ukuze unciphise ukuphazamiseka.
