I. Uhlengahlengiso lohlobo oluPhakathi

1. Iimeko zokusebenza kolwelo

• Ifanelekile kwiilwelo ezicocekileyo, ezithambileyo nezingenamsoco, ezikwisigaba esinye ezifana namanzi empompi, amanzi ajikelezayo emizi-mveliso, ipetroli, idizili, i-methanol, i-ethanol, kunye ne-ethylene glycol.
• Ifuna ukuba inombolo yeReynolds yesixhobo ibe yiRe > 2000 (isantya sokuhamba esiphakathi ukuya kwesikhulu). Imidiya ene-viscosity ephezulu (umz., ioyile enzima, ioyile yokuthambisa) kufuneka ithintelwe, njengoko iya kubangela ukuveliswa kwe-vortex engazinzile kunye nokonakala okubonakalayo kokuchaneka.

2. Iimeko zokusebenza ngegesi

• Ifanelekile kwiigesi ezomileyo nezicocekileyo ezifana negesi yendalo, umoya ocinezelweyo, initrogen, ioksijini, icarbon dioxide, kunye negesi ye-blast furnace (ukungcola kufuneka kuhluzwe).
• Ingahlangabezana neemfuno zokulinganisa iigesi ezikubushushu obuqhelekileyo kunye neziphakathi ukuya kweziphezulu (umz., ukujonga igesi yolwelo). Ingqalelo kufuneka inikwe uxinzelelo oluzinzileyo lwegesi ukuze kuthintelwe ukuguquguquka okukhulu okuchaphazela iziphumo zokulinganisa.

3. Iimeko zokusebenza ngomphunga

• Le yimeko eluncedo kwii-vortex flowmeters, ezifanelekileyo ngakumbi ekulinganisweni komphunga ogcweleyo kunye nomphunga oshushu kakhulu, njengomphunga webhoyila kwizityalo zamandla, umphunga wenkqubo kwizityalo zeekhemikhali, kunye nomphunga kwiinkqubo zokufudumeza.
• Iyakwazi ukumelana nobushushu obuphezulu kunye noxinzelelo oluphezulu (ngokwesiqhelo ubushushu obuyi-≤ 400℃, uxinzelelo oluyi-≤ 16MPa) kunye nokulahleka koxinzelelo oluphantsi, nto leyo enciphisa ukusetyenziswa kwamandla emibhobho.

II. Iimeko zokusebenza zemibhobho kunye nokufakelwa

1. Iimfuno zobubanzi bepayipi

• Ifanelekile kwiidayamitha zepayipi eziphakathi ukuya kwezinkulu ezine-DN ≥ 25mm (edla ngokuba yi-DN25~DN3000). Ukuchaneka kokulinganisa kwiidayamitha zepayipi ezincinci (DN < 25mm) kuphantsi kwaye akukhuthazwa.
• Ixhasa ukufakwa okuthe tye, okuthe nkqo, okanye okuthambekileyo, kodwa kuyimfuneko ukuqinisekisa ukuhamba kombhobho opheleleyo kwizinto ezimanzi okanye ukuhamba okufanayo kweegesi/umphunga ukuze kuthintelwe iipayipi ezingenanto okanye ukuhamba kwegesi-ulwelo okunezigaba ezimbini.

2. Iimfuneko zeCandelo leMibhobho eQondileyo

• Kufuneka ihlangabezane neemfuno zobude beenxalenye zepayipi ezithe tye ngaphambi nasemva kwemitha: ngokwesiqhelo, phezulu ≥ ngokuphindwe kalishumi ububanzi bepayipi kwaye ngezantsi ≥ ngokuphindwe kahlanu ububanzi bepayipi (xa kungekho zinto ziphazamisayo). Ukuba kukho iivalvu okanye iingqiniba, ubude becandelo lepayipi ethe tye kufuneka bonyuswe (umz., phezulu ≥ ngokuphindwe ka-20 ubukhulu bepayipi) ukuqinisekisa intsimi yokuhamba kolwelo oluzinzileyo.

III. Iimeko Zokusebenza Kwendalo Neenkqubo

1. Ubushushu kunye noxinzelelo

• Uluhlu lobushushu: -40℃ ~ 400℃ (iimodeli eziqhelekileyo); ezinye iimodeli ezinobushushu obuphezulu zinokumelana nobushushu obuphezulu (umz., 550℃).
• Uluhlu loxinzelelo: 0~16MPa (iimodeli eziqhelekileyo); iimodeli ezinoxinzelelo oluphezulu zinokuhlangabezana neemeko zokusebenza ezinoxinzelelo oluphezulu ≤ 40MPa (umz., ulwelo oluphezulu kwiindawo zeoyile).

2. Iimfuno zeNdalo

• Ifanelekile kwiindawo zoshishino eziqhelekileyo ezifana nee-petrochemical, umbane, kunye neendawo zokusebenzela ze-metallurgical. Ukuba indawo inomdlidlizo onamandla (umz., kufutshane neepompo), kufuneka kufakwe izixhobo zokudambisa ukungcangcazela; kungenjalo, ukungcangcazela kuya kuphazamisa ukufunyaniswa kwe-vortex kwaye kubangele ukutyibilika kwedatha.
• Ingasetyenziswa kwiimeko ezithintela ukuqhuma (kufuneka izinzwa ezithintela ukuqhuma), njengeendawo ezinokutsha neziqhumayo kwiindawo zeoyile nakwizityalo zeekhemikhali.

IV. Ukulungelelaniswa neeMfuno zoLawulo lweeNkqubo

1. Uluhlu lokuhamba kwamanzi

• Inomlinganiselo obanzi wokujika (1:10~1:30), ifanelekile kwiimeko zokusebenza ezinokuguquguquka okukhulu kokuhamba kwamanzi, njengokulinganiswa kokutya kwiireactors zeekhemikhali kunye nokulinganiswa kokuhamba komphunga ngexesha lokutshintsha komthwalo kwizityalo zamandla.

2. Isiphumo seSignali kunye noHlanganiso

• Ixhasa iziphumo zesignali ezifana ne-4-20mA, i-pulse, i-HART, kunye ne-RS485, kwaye inokuqhagamshelwa ngokuthe ngqo kwiinkqubo ze-PLC kunye ne-DCS ukuhlangabezana neemfuno zokubeka esweni okude kunye nolawulo oluzenzekelayo, njengolawulo lokuhamba komoya oluvaliweyo kwimigca yemveliso yemizi-mveliso.

V. Iimeko Zokusebenza Ekufuneka Ziphephe

1. Ubunzulu obuphezulu (i-kinematic viscosity > 10mm²/s), ubungakanani obuphezulu obuqinileyo (ubungakanani bezinto eziqinileyo > 1%), kulula ukubunyibilikisa, okanye ukubulinganisa ngokulula.
2. Izinga lokuhamba kwamanzi eliphantsi (inombolo kaReynolds Re < 2000) kunye neemeko zobubanzi obuncinci (DN < 25mm).
3. Ukuhamba kwegesi-ulwelo olunezigaba ezibini okanye ukuhamba kwezigaba ezibini okuqinileyo kolwelo (umz., ulwelo olunamaqamza, amanzi amdaka aqulethe ukungcola okuninzi).
4. Iindawo ezine-vibration enamandla okanye ukuphazamiseka okukhulu kwe-electromagnetic (ngaphandle kweendlela zokukhusela).
