Kuyera huwandu hwezvinwiwa mumatangi, midziyo nemasilo nemazvo uye zvakavimbika kunogona kuva chinhu chakakosha pakati penzvimbo dzekutonga mashandiro emaindasitiri. Zvinotumira pressure nedifferential pressure (DP) ndizvo zvinonyanya kushanda pakushandisa kwakadaro, zvichiratidza huwandu nekuyera hydrostatic pressure inoburitswa nemvura.
Kana Kuisa Kwakananga Kwakundikana
Chinodhinda chakajairwa kana kuti chinotumira DP chinowanzoiswa zvakananga pachiteshi chekubatanidza mashandiro (process connection port) icho chinonzwa diaphragm yacho chakabatana zvakananga nechinhu chinodhinda mashandiro (process medium). Kunyange zvazvo izvi zvichishanda kune mvura isina njodzi senge mvura yakachena, mamwe mamiriro ezvinhu emaindasitiri anoita kuti nzira iyi yakananga isashande:
Midhiya inodziya zvakanyanya:Mvura inopisa zvakanyanya inogona kudarika tembiricha yekushanda yakachengeteka yemagetsi emuchina wekutumira uye sensor. Kupisa uku kunogona kukonzera kuyerera kwekuyera, kukuvadza zvikamu zvemukati uye kuomesa mvura inozadza iri mukati.
Mvura Inopenya, Inotsvedza, kana Inosimbisa:Zvinhu zvakaita semafuta akakora, pulp, sirapu, kana makemikari anonamira pakutonhorera zvinogona kuvhara mitsetse yekufema kana bhora diki rinoita kuti diaphragm inzwe. Izvi zvinotungamira pakuyera zvishoma nezvishoma kana kuti kuvharika zvachose.
Zvinhu Zvinoparadza Kana Zvinokuvadza:Asidhi, caustics, uye slurry dzine zvidimbu zvinogumbura zvinogona kukurumidza kukanganisa kana kuparadza diaphragm yechinhu chinotumira mashoko, zvichikonzera kutadza kushanda kwemidziyo uye kubuda kwemvura.
Mashandisirwo Ehutsanana/Utsanana:Mumaindasitiri ezvekudya, zvinwiwa, uye mishonga, maitiro acho anoda kucheneswa nguva dzose munzvimbo kana kuurayiwa kwehutachiona munzvimbo. Matransmitter anofanirwa kugadzirwa asina makumbo akafa kana mitswe uko mabhakitiriya anogona kukura, zvichiita kuti mayuniti akajairwa ekuisa zvakananga asatevedzere zvinodiwa.
Kutenderera Kwemaitikiro kana Kudedera:Mukushandiswa kune kuputika kukuru kana kudedera kwemuchina, kuisa transmitter zvakananga kumudziyo kunogona kutumira masimba aya ku sensor inonzwisisika, zvichikonzera kuverenga kune ruzha, kusina kuvimbika uye kuneta kwemuchina.
Kuzivisa Sisitimu Yekuvharira Diaphragm Yekure
Chisimbiso che diaphragm chiri kure (chinozivikanwawo sechisimbiso chemakemikari kana gauge guard) inzira yakagadzirirwa kuchengetedza chinotumira kubva mumamiriro ezvinhu aya akaipa. Chinoshanda sechidziviriro chakasimba, chinoparadzanisa chine zvikamu zvitatu zvakakosha:
Chisimbiso cheDiaphragm:Kamudzira kanochinjika, kanodzivirira ngura (kanowanzogadzirwa nezvinhu zvakaputirwa neSS316, Hastelloy, Tantalum kana PTFE) kanosangana zvakananga nemvura inoyerera kuburikidza neflange kana clamp connection. Diaphragm inotsauka nekuda kwekumanikidzwa kweprocess.
Chubhu yeCapillary:Kapilari yakavharwa yakazadzwa nemvura inozadza system yakasimba, isingadzvanyike (yakadai semafuta esilicone neglycerin). Chubhu iyi inobatanidza chisimbiso chediaphragm kune diaphragm inonzwa transmitter.
Mutakuri:Chinodzvanywa kana kuti chinotumira DP pachacho, chave kuparadzaniswa nechinhu chiri kure.
Nheyo yekushanda kwayo yakavakirwa paMutemo waPascal wekutumira kumanikidzwa kwemvura. Kumanikidzwa kwemaitiro kunoshanda pa diaphragm yechisimbiso chiri kure, zvichiita kuti itsauke. Kutsauswa uku kunodzvinyirira mvura inozadza iri mukati me capillary system iyo inobva yatumira kumanikidzwa uku nema hydraulic kuburikidza ne capillary tube kuenda ku transmitter's sensing diaphragm. Saka inoyera kumanikidzwa nemazvo pasina kumbosangana nemamiriro ezvinhu anonetsa.
Zvakanakira Zvikuru uye Zvakanakira Zvehurongwa
Kushandiswa kwesystem yekuvharira kure kunopa mabhenefiti akawanda anobatsira zvakananga mukuvandudza mashandiro, kuchengetedzeka, uye kuchengetedza mari.
Kudzivirirwa Kwemidziyo Kusingaenzaniswi uye Kugara Kwenguva Refu:
Chinoshanda sechidziviriro, chivharo cheremote chinotora mutoro wese wemamiriro ezvinhu uye chinotumira chinodzivirirwa kubva pakupisa kwakanyanya, ngura, kukweshwa uye kuvharika. Chinowedzera hupenyu hwebasa rechinotumira, zvichideredza kuwanda kwekuchitsiva uye mutengo wese wekuva muridzi.
Kururama uye Kuvimbika Kwekuyera Kwakawedzerwa:
Muzviitiko zvekuisa zvakananga, mitsetse yekufema yakavharika ndiyo inonyanya kukonzera kukanganisa. Zvisimbiso zvekure zvinobvisa kudiwa kwemitsetse mirefu yekufema iyo inogona kukundikana. Sisitimu iyi inopa chinongedzo chakananga, chakachena chehydraulic kune maitiro acho, ichivimbisa kuverenga kwakanaka uye kwakarurama, kunyangwe kune mvura inonamira kana slurry.
Kuyera Kuvhura Mumamiriro Ekunze Akanyanya:
Zvisimbiso zviri kure zvinogona kusarudzwa nezvinhu zvakakosha uye mvura inozadzwa yakayerwa tembiricha yakakwira zvakanyanya kana kuti inopenya. Chinotumira chinogona kuiswa kure nekupisa, zvichiita kuti magetsi acho ashande mukati mekupisa kwakatarwa. Izvi zvakakosha mukushandiswa senge midziyo yereactor, madhiramu eboiler, kana matangi ekuchengetera cryogenic.
Kugadzirisa Kwakareruka uye Kuderedza Nguva Yekuzorora:
Kana kubatana kwemaitiro kuchida kugadziriswa, chinotumira chine chisimbiso chiri kure chinogona kuparadzaniswa uye kubviswa pasina kudonhedza mvura mumudziyo wese. Uyezve, kana chisimbiso chacho chikakuvara, chinogona kutsiviwa pasina chinotumira, izvo zvinogona kuva kugadzirisa kusingadhuri zvakanyanya uye nekukurumidza.
Kuchinjika muKuisa:
Chubhu ye capillary inobvumira transmitter kuiswa panzvimbo iri nyore uye iri nyore kusvika—kure nenzvimbo dzinodedera zvakanyanya, nzvimbo dzakaoma kusvika dziri pamusoro petangi, kana nzvimbo dzakamanikana. Izvi zvinoita kuti kuiswa, kutariswa, uye kuongororwa kwekugadzirisa nguva dzose kuve nyore.
Kuve nechokwadi chekuti maitiro akachena uye hutsanana:
Mumaindasitiri ehutsanana, zvisimbiso zve diaphragm zvinoiswa mumvura zvinoita kuti pave nenzvimbo yakatsetseka, isina mitswe iri nyore kuchenesa uye kuuraya utachiona, zvichidzivirira kusvibiswa kwebhakitiriya.
Chisimbiso che diaphragm chiri kure chinobatsira pakuyera mazinga nenzira yakavimbika uye yakarurama munzvimbo dzinonyanya kuomera maindasitiri. Nekugadzira chipingamupinyi chinodzivirira, chinobvumira ma "pressure" uye ma "differential pressure transmitters" kuita mabasa avo zvakachengeteka uye zvinobudirira, kure ne "crusting", "clogging" kana kuti "thermal extreme" yemaitiro acho. ShanghaiWangyuanikambani yekugadzira tekinoroji yepamusoro inonyanya kugadzira nekugadzira zvishandiso zvekuyera kumanikidzwa ine ruzivo rwemakore anopfuura makumi maviri. Kana uine chero zvinodiwa kana mibvunzo maererano nazvozvinotumira chisimbiso chediaphragm zviri kure, ndapota musazeza kutibata.
