Cov kauj ruam rau kev txhim kho ib qho ruaj khovultrasonic flow meteryog raws li nram no:
Ua ntej, teeb tsa cov yeeb nkab tshwj xeeb, xws li sab nraud, sab hauv txoj kab uas hla, phab ntsa thickness, ntsuas cov kua, sensor hom, installation txoj kev, thiab lwm yam. Thaum kawg, txiav txim siab qhov kev ncua deb thiab kho lub sensor rau cov yeeb nkab raws li qhov kev ncua deb.
Ceev cov ntsuas ntsuas thiab ceev cov txheej txheem installation
I.Parameter nqis:
1. Ntaus MENU 1 1 nkag mus rau lub qhov rais 11, ces nias ENT nkag mus. Nkag mus rau cov yeeb nkab sab nraud thiab nias ENT kom paub meej.
2. Ntaus ▼/- mus rau hauv qab thiab nkag mus rau lub qhov rais 12, ces nias ENT nkag. Nkag mus rau cov yeeb nkab phab ntsa tuab thiab nias ENT kom paub meej.
3. Ntaus ▼/- mus rau hauv qab thiab nkag mus rau lub qhov rais 14, ces nias ENT nkag. Siv ▲/+ lossis ▼/- tus yuam sij los xaiv cov khoom siv yeeb nkab thiab nias ENT kom paub meej.
4. Ntaus ▼/- mus rau hauv qab thiab nkag mus rau lub qhov rais 16, ces nias ENT nkag. Siv tus yuam sij ▲/+ lossis ▼/- los xaiv cov ntaub ntawv hauv ob sab phlu thiab nias ENT kom paub meej.
5. Ntaus ▼/- mus rau hauv qab thiab nkag mus rau lub qhov rais 20, ces nias ENT nkag. Siv ▲/+ lossis ▼/- tus yuam sij los xaiv hom kua dej thiab nias ENT kom paub meej.
6. Ntaus ▼/- mus rau hauv qab thiab nkag mus rau lub qhov rais 23, ces nias ENT nkag. Siv ▲/+ lossis ▼/- tus yuam sij los xaiv hom sensor thiab nias ENT.
7. Ntaus ▼/- mus rau qhov rais 24, ces nias ENT. Siv ▲/+ lossis ▼/- tus yuam sij los xaiv txoj kev teeb tsa thiab nias ENT kom paub meej.
8. Hom ▼/- mus rau nqes mus rau qhov rais 25. Nruab lub sensor raws li qhov kev teeb tsa nyob deb thiab cov txheej txheem kev teeb tsa tau xaiv hauv cov kauj ruam dhau los (saib Sensor Installation).
9. Ntaus MENU 2 6 nkag mus rau lub qhov rais 26, ces nias ENT. Siv tus yuam sij ▲/+ lossis ▼/- los xaiv "1. Ua kom muaj zog thiab siv tag nrho".
Tom qab ntawd nias ENT ob zaug kom paub meej (cov kauj ruam no tseem ceeb heev).
II. Kev xaiv thiab qhov chaw ntawm kev ntsuas thiab teeb tsa cov ntsiab lus:
1. Qhov zoo tshaj plaws, cov yeeb nkab seem yuav tsum ncaj, tsawg kawg yog 10D los ntawm kev khoov sab saud thiab 5D hauv qab (saib phau ntawv qhia kom paub meej). Yog tias qhov no ua tsis tau, nruab qhov kev sojntsuam kom ze rau nruab nrab, me ntsis hauv qab. D yog lub taub sab nraud ntawm cov yeeb nkab.
2. Yog hais tias muaj rwb thaiv tsev ntawm cov yeeb nkab, tshem tawm ib feem ntawm lub rwb thaiv tsev txheej raws li qhov kev ncua deb thiab txoj kev. Tom qab muab tso rau, xyuas kom meej tias ob lub sensors nyob rau tib lub dav hlau axial. Cov sensors yuav tsum tau nruab rau ntawm sab ntawm cov yeeb nkab, tsis yog nyob rau sab saum toj lossis hauv qab (raws li qhia hauv daim duab).
III. Installation ntawm Sab Nraud Clamp Sensors:
Hauv kev ntsuas tiag tiag, xav txog qhov muaj huab cua npuas nyob rau sab sauv ntawm cov yeeb nkab thiab cov av hauv qab, yuav tsum zam qhov 6 teev / 12 teev. Kev sojntsuam yuav tsum tau muab ntsia rau ntawm ob sab kab rov tav ntawm cov yeeb nkab. Yog tias qhov chaw txwv, qhov kev sojntsuam tuaj yeem ntsia tau ntsug lossis ntawm lub kaum sab xis, yog tias cov yeeb nkab puv ntawm cov kua thiab tsis muaj cua npuas.
1: V- txoj kev teeb tsa muaj feem xyuam rau cov yeeb nkab txoj kab uas hla ntawm DN32 txog DN100. Schematic sab saum toj/hauv qab saib.
2: Z- txoj kev teeb tsa siv tau rau cov kav dej loj dua DN100. Schematic sab saum toj/hauv qab saib.
Ⅳ. Sib tsoo lub Installation Point:
Cov kav hlau yuav tsum yog hauv av. Siv lub kaum sab xis grinder lossis cov ntaub ntawv ncaj los zom ib cheeb tsam square kwv yees li 1.5 npaug ntawm thaj tsam ntawm qhov kev sojntsuam hauv qab ntawm qhov chaw teeb tsa los pab txhawb kev sojntsuam txav thiab pom kev ntsuas teeb liab hloov kho. (PVC kav tsis tas yuav sib tsoo; tsuas yog so kom huv si.) Tom qab sib tsoo, qhov saum npoo yuav tsum ci, du, thiab tsis muaj xeb.
V. Kev sojntsuam thiab kev hloov kho:
1. Ultrasonic flow meter muaj ob qhov kev sojntsuam, nce thiab nqis.
Ua ntej, sib npaug ntawm 1-2 hli tuab txheej ntawm tus neeg sawv cev sib txuas los yog silicone rau hauv qab ntawm qhov chaw sojntsuam. Tom qab ntawd, muab cov kev sojntsuam mus rau hauv av taw tes rau ntawm cov kav dej ntws thiab ruaj ntseg nrog lub pluaj steel (kom muaj kev sib txuas zoo ntawm qhov kev sojntsuam hauv qab thiab cov yeeb nkab nto, tsis muaj cua npuas, grit, lossis lwm yam impurities).
Ⅵ. Kev teeb tsa video rau clamp-rauUltrasonic flow meter (TUF-2000B, TUF-2000M, TUF-2000S):
