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 yemudziyo wakavhurika, mutakuridzi anoiswa padyo nepasi pegaba 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 kudzvinyirira 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 yekumanikidza kukosha kwekuyera iyo yakakwira yekumanikidza divi;
D chiyero che zero migration.
Iyo musimboti weyakapetwa 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 yekuyera 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-kudzvanya padivi inotungamira chubhu yetransmitter neimwe mvura. Mamiriro ezvinhu aya anonzi wet pressure guiding connection.
Mumamiriro ezvinhu ari pamusoro apa, kune musoro wekumanikidza pane yakaderera yekumanikidza divi remupepeti, saka kutama kwakashata kunofanirwa kuitwa (ona Mufananidzo 1-2)
Mufananidzo 1-2 Muenzaniso wekuyera kwemvura mumudziyo wakavharwa
Rega X ive chinhambwe chakatwasuka pakati peyakaderera uye yepamusoro-soro mvura nhanho kuyerwa, X = 2450mm. Y ndiyo chinhambwe chakatwasuka kubva kudzvinyiriro yechiteshi cheiyo transmitter kusvika kune yakaderera mvura level, Y = 635mm.
Z ndiyo chinhambwe kubva pamusoro pemvura-yakazadzwa nedzvinyiriro inotungamira chubhu kusvika kune yekutanga mutsara weiyo transmitter, Z=3800mm,
ρ1 ndiko kuwanda kwemvura, ρ1=1.
ρ2 ndiko kuwanda kwemvura inozadza yeyakadzika-kudzvanywa 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 (es) kusvika (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 rekudzvinyirira;
P1 ndiyo yekumanikidza kukosha kwekuyera iyo yakakwira yekumanikidza divi;
D chiyero che zero migration.
Installation Precautions
Single flange installation nyaya
1. Kana iyo imwe chete flange yekuzviparadzanisa membrane membrane transmitter yematangi akavhurika ichishandiswa kuyera yemvura kuyerwa kwematangi emvura akavhurika, iyo L side yeyakaderera kudzvanywa side interface inofanira kuvhurika kumhepo.
2. Kune yakavharwa tangi yemvura, iyo yekumanikidza inotungamira chubhu yekutungamira kudzvanywa mudhangi remvura inofanira kunge iri pombi padivi reL yeyakadzika kudzvinyirira 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 nekuiswa kweflange padivi rekudzvanya-kudzvanya sezvakaratidzwa muMufananidzo 1-3. Iyo flange padivi petangi kazhinji 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 peyakanyanya-kudzvanya 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, iyo capillary chubhu padivi rekudzvanya-yakakwirira inogona kusungirirwa pamwe chete uye kugadziriswa kudzivirira kupesvedzera kwemhepo uye kuzununguka (iyo capillary machubhu eiyo super refu chikamu inofanira kukungurutswa pamwe nekugadziriswa).
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 seal yekumisikidza chikamu, kuitira kuti kudonha kwekudzvanywa 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 kwekugumira kwekuisa mamiriro. Kana kana iyo transmitter body inogona kuiswa pamusoro peiyo flange seal yekumisikidza chikamu nekuda kwezvikonzero zvechinangwa, chinzvimbo chayo chekuisa chinofanira kusangana neinotevera calculation formula.
1) h: kureba pakati peyekure flange diaphragm seal yekuisa chikamu uye transmitter body (mm);
① Kana h≤0, iyo transmitter body inofanirwa kuiswa pamusoro h (mm) pazasi peflange diaphragm seal yekuisa 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℃.
