Mukuita kugadzirwa kwemaindasitiri nekugadzira, mamwe matangi akayerwa ari nyore kupenya, ane viscous zvakanyanya, anoparadza zvakanyanya, uye ari nyore kuomesa.Imwe uye yakapetwa kaviri flange mutsauko wekudzvanya ma transmitters anowanzo shandiswa mune izvi zviitiko., Zvakadai se: matangi, shongwe, maketero, uye matangi mumiti yekubikira;mvura yekuchengetera matangi ekugadzira evaporator mayunitsi, mvura nhanho yekuchengetera matangi e desulfurization uye denitrification zvidyarwa.Vese vari vaviri hama dzisina kuroora uye mbiri flange dzine akawanda maapplication, asi akasiyana nemusiyano pakati pekuvhurika nekunamwa.Single-flange yakavhurika matangi anogona kuvharwa matangi, nepo maflange maviri ane mamwe akavharwa matangi evashandisi.
Iyo musimboti weimwe flange pressure transmitter inoyera fluid level
Iyo single-flange pressure transmitter inoita nhanho shanduko nekuyera density yetangi rakavhurika, Level kuyerwa kwemidziyo yakavhurika.
Pakuyera mwero wemvura wemudziyo wakavhurika, chinotakurisa chinoiswa padhuze nechepazasi pemudziyo kuyera kudzvanywa kunoenderana nekukwirira kweyero yemvura pamusoro payo.Sezvinoratidzwa mumufananidzo 1-1.
Kudzvanywa kweyero yemvura yemudziyo yakabatana kune yakakwira yekumanikidza divi reiyo transmitter, uye iyo yakaderera yekumanikidza divi yakavhurika kumhepo.
Kana iyo yakaderera mvura mwero weyero yakayerwa yemvura nhanho shanduko iri pamusoro penzvimbo yekumisikidza yemupepeti, mupepeti anofanira kuita kutama kwakanaka.
Mufananidzo 1-1 Muenzaniso wekuyera mvura mumudziyo wakashama
Rega X ive chinhambwe chakatwasuka pakati peyakadzika uye yepamusoro-soro mvura nhanho kuyerwa, X = 3175mm.
Y ndiyo chinhambwe chakatwasuka kubva padzvinyiriro yechiteshi chemutakuri kusvika padanho remvura rakaderera, y = 635mm.ρ ndiko kuwanda kwemvura, ρ=1.
h ndiyo yakanyanya kudzvanywa musoro inogadzirwa neiyo mvura column X, muKPa.
e ndiwo musoro wekumanikidza unogadzirwa neiyo liquid column Y, muKPa.
1mH2O=9.80665Pa (zvakafanana pazasi)
Kuyeresa kunobva ku e kuenda ku e+h saka: h=X·ρ=3175×1=3175mmH2O=31.14KPa
e=y·ρ=635×1= 635mmH2O= 6.23KPa
Kureva kuti, kuyerwa kweiyo transmitter ndeye 6.23KPa～37.37KPa.
Muchidimbu, isu tinonyatso kuyera kureba kweyero yemvura:
Kureba kwemwero wemvura H=(P1-P0)/(ρ*g)+D/(ρ*g);
Cherechedza: P0 ndiyo ikozvino mhepo yemhepo;
P1 ndiyo kukosha kwekumanikidza kuyera iyo yakakwira yekumanikidza divi;
D ndiyo nhamba ye zero migration.
Iyo musimboti wembiri flange pressure transmitter kuyera fluid level
Iyo kaviri-flange pressure transmitter inoita nhanho shanduko nekuyera density yetangi rakavharwa: Dry impulse connection.
Kana gasi riri pamusoro pemvura yakadzika isingadziviriri, pombi yekubatanidza padivi repasi-kudzvanywa kweiyo transmitter inoramba yakaoma.Iyi mamiriro anonzi dry pilot connection.Iyo nzira yekuona iyo yekuyeresa huwandu hweiyo transmitter yakafanana neyeyero yemvura mumudziyo wakashama.(Ona Mufananidzo 1-2).
Kana iyo gasi pairi mvura ikanyunguduka, mvura inozoungana zvishoma nezvishoma muhubhu inotungamira padivi repasi rekumanikidza redhisheni, izvo zvinokonzeresa kukanganisa kuyerwa.Kuti ubvise chikanganiso ichi, pre-zadza iyo yakaderera-kutsikirira padivi inotungamira chubhu yetransmitter neimwe mvura.Situation iyi inonzi wet pressure guiding connection.
Mumamiriro ezvinhu ari pamusoro apa, kune musoro wekumanikidza pane yakaderera kudzvinyirirwa padivi reiyo transmitter, saka kutama kwakashata kunofanirwa kuitwa (ona Mufananidzo 1-2)
Mufananidzo 1-2 Muenzaniso wechiyero chemvura mumudziyo wakavharwa
Rega X ive chinhambwe chakatwasuka pakati peyakadzika uye yepamusoro-soro mvura nhanho kuyerwa, X = 2450mm.Y ndiyo chinhambwe chakatwasuka kubva kudzvinyiriro yechiteshi chemutakuri kusvika padanho remvura rakaderera, Y=635mm.
Z ndiyo chinhambwe kubva pamusoro pemvura-yakazadzwa nedzvinyiriro inotungamira chubhu kusvika kune base mutsara weiyo transmitter, Z=3800mm,
ρ1 ndiko kuwanda kwemvura, ρ1=1.
ρ2 ndiko kuwanda kwemvura inozadza yeyakadzika-kudzvanya side conduit, ρ1=1.
h ndiyo yakanyanya kudzvanywa musoro inogadzirwa neyakaedzwa mvura column X, muKPa.
e ndiyo yakanyanya kudzvanywa musoro inogadzirwa neyakaedzwa mvura column Y, muKPa.
s ndiwo musoro wekumanikidza unogadzirwa neyakarongedzerwa mvura column Z, muKPa.
Chiyero chechiyero chinobva ku (es) kuenda ku (h+es), ipapo
h=X·ρ1=2540×1 =2540mmH2O =24.9KPa
e=Y·ρ1=635×1=635mmH2O =6.23KPa
s=Z·ρ2=3800×1=3800mmH2O=37.27KPa
Saka: es=6.23-37.27=-31.04KPa
h+e－s=24.91+6.23－37.27=－6.13KPa
Ongorora: Muchidimbu, tinonyatso kuyera kureba kweyero yemvura: nhanho yemvura urefu H=(P1-PX)/(ρ*g)+D/(ρ*g);
Ongorora: PX ndeyekuyera kukosha kwekumanikidzwa kwedivi rekumanikidza rakaderera;
P1 ndiyo kukosha kwekumanikidza kuyera iyo yakakwira yekumanikidza divi;
D ndiyo nhamba ye zero migration.
Installation Precautions
Single flange installation nyaya
1. Kana iyo imwe chete flange yekuzviparadzanisa membrane membrane transmitter yematangi akavhurika ichishandiswa kuyera yemvura kuyerwa kweakavhurika emvura matangi, iyo L side yeyakaderera pressure side interface inofanirwa kuvhurika kumhepo.
2. Kune yakavharwa tangi yemvura, iyo yekumanikidza inotungamira chubhu yekutungamira kudzvanywa mudhangi remvura inofanira kunge iri pombi padivi reL yeyakaderera kudzvanya side interface.Inotsanangura kudzvanywa kwetangi.Mukuwedzera, nguva dzose usunungure valve yekudhonza padivi reL kuti ubvise condensate muL side chamber, kana zvisina kudaro inokonzera kukanganisa mukuyera kwemvura.
3. Iyo transmitter inogona kubatanidzwa kune iyo flange yekumisikidza padivi repamusoro-kudzvanywa sezvakaratidzwa muFigure 1-3.Iyo flange padivi petangi inowanzoita inofambiswa flange, iyo inogadziriswa panguva iyoyo uye inogona kusungirirwa nekudzvanya kumwe chete, izvo zviri nyore kuisirwa pa-saiti.
Mufananidzo 1-3 Kuisa muenzaniso weflange mhando yemvura level transmitter
1) Pakuyera mwero wemvura yetangi remvura, iyo yakaderera mvura mwero (zero point) inofanirwa kuiswa chinhambwe che50mm kana kupfuura kubva pakati peiyo high-pressure side diaphragm chisimbiso.Mufananidzo 1-4:
Mufananidzo 1-4 Kuisa muenzaniso wemvura tank
2) Isa iyo flange diaphragm pakakwirira (H) uye yakaderera (L) yekumanikidza divi retangi sezvakaratidzwa pane transmitter uye sensor label.
3) Kuti uderedze pesvedzero yemusiyano wekushisa kwezvakatipoteredza, machubhu ecapillary ari padivi rekudzvanywa kwepamusoro anogona kusungwa pamwe chete uye kugadziriswa kudzivirira kufurira kwemhepo uye kudedera (iyo capillary machubhu echikamu chakareba kwazvo chinofanira kukungurutswa pamwechete. uye yakagadziriswa).
4) Panguva yekuisa basa, edza kusaisa kudonhedza kwemvura yekuisa chisimbiso kune diaphragm chisimbiso zvakanyanya sezvinobvira.
5) Iyo transmitter body inofanirwa kuiswa chinhambwe chinodarika 600mm pazasi peyakanyanya-kudzvanya padivi kure flange diaphragm chisimbiso chekuisa chikamu, kuitira kuti iyo inodonha yekudonha kweiyo capillary seal fluid inowedzerwa kumuviri wetransmitter zvakanyanya sezvinobvira.
6) Ehe, kana isingagone kuisirwa 600mm kana kupfuura pazasi peiyo yekumisikidza chikamu cheflange diaphragm chisimbiso chikamu nekuda kwekudzikiswa kwemamiriro ekuisa.Kana kana iyo transmitter body inogona kuiswa chete pamusoro peiyo flange seal yekumisikidza chikamu nekuda kwezvikonzero zvechinangwa, chinzvimbo chayo chekuisa chinofanira kusangana neinotevera calculation formula.
1) h: kureba pakati peiyo kure flange diaphragm seal yekuisa chikamu uye transmitter body (mm);
① Kana h≤0, iyo transmitter body inofanirwa kuiswa pamusoro h (mm) pazasi peflange diaphragm chisimbiso chekuisa chikamu.
②Kana h> 0, iyo transmitter body inofanirwa kuiswa pazasi h (mm) pamusoro peiyo flange diaphragm seal yekuisa chikamu.
2) P: Kumanikidzwa kwemukati kwemvura tank (Pa abs);
3) P0: Muganho wakaderera wekumanikidza kunoshandiswa nemuviri wekutumira;
4) Ambient tembiricha: -10～50℃.
