Ungayiqinisekisa njani indlela yokuchaneka kwee-vortex flowmeters kwiindawo ezinobushushu obuphezulu?

Ukuqinisekisa ukuchaneka kwee-vortex flowmeters kwiindawo ezinobushushu obuphezulu, indibaniselwano yokwenziwa ngcono kokukhethwa kweemodeli, ukhuseleko lokufakelwa, amaqhinga okulinganisa, kunye nokugcinwa kokusebenza kuyafuneka. Apha ngezantsi kukho isikhokelo esicwangcisiweyo nesisebenzayo esilungiselelwe iimeko zobushushu obuphezulu:

1. Khetha iiModeli kunye nezixhobo ezilungiselelwe ubushushu obuphezulu

• Khetha ii-vortex flowmeters ezikhethekileyo zobushushu obuphezulu: Khetha iimodeli ezilinganiswe ngokucacileyo kuluhlu lobushushu olujolise kulo (umz., 400–550℃ kwizicelo zoshishino ezigqithisileyo). Ezi modeli zinezakhiwo ze-sensor eziqinisiweyo kunye nezixhobo ze-elektroniki ezimelana nobushushu obuphezulu ukuthintela ukushukuma kwesignali okubangelwa kukwanda kobushushu.
• Qinisekisa ukuba izinto ziyahambelana:
  • I-sensor probe kufuneka yenziwe ngee-alloys ezinobushushu obuphezulu (umz., i-Inconel 625) okanye izinto zeseramikhi ukuze zikwazi ukumelana nokugqwala kunye nokuguquka kobushushu.
  • Izixhobo zokutywina (umz., ii-gaskets) kufuneka zisebenzise izinto ezimelana nobushushu ezifana nee-graphite okanye ii-gaskets zesinyithi endaweni yerabha eqhelekileyo, enokonakala xa kushushu kakhulu kwaye ibangele ukuvuza okanye iimpazamo zokulinganisa.
  • Izinto zecandelo lombhobho kufuneka zihambelane nenkqubo ephakathi kunye nobushushu ukuthintela ukungalingani kokwandiswa kobushushu okuphazamisa intsimi yokuhamba kolwelo.

2. Lungiselela ukufakwa ukuze unciphise ukuphazamiseka kobushushu

• Yahlula i-transmitter kumaqondo obushushu aphezulu: Uninzi lwee-vortex flowmeter transmitters azenzelwanga ukuvezwa ngqo kumaqondo obushushu aphezulu. Faka i-transmitter kude (umz., imitha eyi-1-2 ukusuka kwi-sensor) usebenzisa iintambo zokwandisa, okanye ufake izikhuselo zobushushu/ubushushu phakathi kwe-sensor kunye ne-transmitter. Kwiimodeli ezidibeneyo, khetha ezo zine-transmitter enclosures ezisusa ubushushu.
• Qinisekisa ukuba kukho iimeko ezizinzileyo zokuhamba kwamanzi: Nciphisa ukuphazamiseka kokungcangcazela: Iindawo ezishushu kakhulu zihlala ziquka iimpompo okanye iicompressor ezivelisa ukungcangcazela. Faka iibrakethi zokudambisa ukungcangcazela phakathi kwe-flowmeter kunye nombhobho, kwaye usebenzise izihlanganisi eziguquguqukayo ukuze zahlule ukungcangcazela koomatshini, okunokulinganisa imiqondiso ye-vortex kwaye kubangele ukufundwa okungachanekanga.
  • Gcina iindawo ezifunekayo zemibhobho ethe tye (ephezulu ≥ 10×DN, ezantsi ≥ 5×DN; yongeza uye phezulu ≥ 20×DN ukuba iivalvu/iingqiniba zikufutshane) ukuze kuthintelwe ukuphazamiseka kokuhamba kwamanzi okubangelwa kukwahlulwa kobushushu kwimibhobho enobushushu obuphezulu.
  • Faka i-flowmeter ngendlela ethe nkqo ukuze i-gas/steam media ithintele iipokotho zomoya okanye ukuqokelelwa kwe-condensate, okunokuphazamisa ukuveliswa kwe-vortex. Kwizinto ezimanzi, qinisekisa ukuhamba kombhobho opheleleyo ukuze kuthintelwe iimpazamo zemibhobho engenanto.

3. Linganisa iimeko zokusebenza ezikumgangatho ophezulu

• Linganisa phantsi kobushushu bokwenyani bokusebenza: Ukulinganiswa okuqhelekileyo kwelebhu (ngokwesiqhelo kubushushu begumbi) kusenokungabonisi ukusebenza kubushushu obuphezulu. Yenza ukulinganiswa kwangaphakathi okanye uthumele i-flowmeter kwilebhu yokulinganisa enokulinganisa ubushushu bakho bokusebenza kunye neemeko zoxinzelelo. Oku kubonakalisa iziphumo zobushushu kwi-sensor kunye neempawu zolwelo (umz., i-viscosity, utshintsho loxinano kumphunga).
• Sebenzisa iimodeli ezihlawulelwa ubushushu: Kwizicelo zomphunga okanye zegesi, khetha ii-vortex flowmeters ezineenzwa zobushushu ezakhelwe ngaphakathi kunye noxinzelelo (iimodeli ezinokuguquguquka). Ezi modeli zihlawulela ngokuzenzekelayo utshintsho kubuninzi bolwelo kunye nesantya esibangelwa kukuguquguquka kobushushu, ziqinisekisa ukubalwa okuchanekileyo kobunzima/umthamo ngaphandle kohlengahlengiso olwenziwe ngesandla.
• Misela ishedyuli yokulinganisa rhoqo: Amaqondo obushushu aphezulu anokukhawulezisa ukuguguleka kwezixhobo. Lungisa i-flowmeter rhoqo kwiinyanga ezi-6 ukuya kwezi-12 (okanye ngokwemigangatho yoshishino efana ne-JJG 1030-2007) ukuqinisekisa ukuchaneka nokulungelelanisa naluphi na uguquko.

4. Sebenzisa uLondolozo kunye nokuBeka esweni ukuSebenza

• Jonga ubushushu kunye nokusebenza ngexesha langempela: Hlanganisa i-flowmeter kunye nenkqubo yakho ye-DCS/PLC ukuze ulandelele idatha yobushushu kunye nokuhamba. Seta izilumkiso zokunyuka okungaqhelekanga kobushushu okanye ukuphambuka kwesantya sokuhamba, okunokubonisa ukonakala kwesensor okanye iingxaki zokufakelwa.
• Yenza ulondolozo rhoqo: Kuphephe ukutshayiswa bubushushu: Xa uqalisa okanye ucima inkqubo, lungisa ubushushu kancinci kancinci ukuze uthintele ukwanda/ukubhitya kobushushu ngokukhawuleza, okunokonakalisa icandelo lesensor okanye lombhobho.
  • Hlola izinto zokuvala ukuze ubone iimpawu zokuwohloka kobushushu (umz., ukuqhekeka, ukuqina) uze uzitshintshele endaweni yazo.
  • Coca i-sensor probe rhoqo ukuze ususe naluphi na ulusu okanye iidiphozithi ezinokuthintela ukubonwa kwe-vortex—sebenzisa izinto zokucoca ezihambelana nobushushu obuphezulu ukuze ungonakalisi i-probe.
  • Jonga iintambo zokwandisa kunye neentambo zoqhagamshelo ukuba azinamonakalo obangelwe bubushushu (umz., ukuqhekeka kwe-insulation) kwaye uzitshintshe ukuba kuyimfuneko.

5. Jongana nezinto eziqwalaselwayo malunga nolwelo

• Kwizicelo zomphunga: Qinisekisa ukuba umphunga ugcwele ngokupheleleyo okanye ushushu kakhulu (akukho mathontsi olwelo) ukuze uphephe ukuhamba kwezigaba ezibini, nto leyo ephazamisa ukwakheka kwevortex. Sebenzisa umgibe womphunga phezulu ukuba kuyimfuneko ukususa i-condensate.
• Kwizinto ezisebenzisa ulwelo oluphezulu: Qinisekisa ukuba inani leReynolds lesixhobo lihlala lingaphezulu kwama-2000 (ubuncinci bokuveliswa kwe-vortex ezinzileyo) kubushushu bokusebenza. Amaqondo obushushu aphezulu anokunciphisa i-viscosity yolwelo, nto leyo enokunceda ukugcina inani elifanelekileyo leReynolds—bala oku usebenzisa idatha yokwenyani ye-viscosity exhomekeke kubushushu.
