Differential pressure kuyerwa kunoita basa rakakosha mumaindasitiri nekutengesa mashandisirwo, sezvo zvinosanganisira kutarisa uye kudzora mutsauko wekumanikidza pakati pemapoinzi maviri mukati mehurongwa. Iyi yekuyera nzira haingovimbisi kuchengetedzwa kwekushanda chete asiwo inowedzera kushanda kwesimba uye inova nechokwadi chemhando yezvigadzirwa nemasevhisi. Mukudziisa, kufefetedza, uye mhepo yekumisikidza masisitimu (HVAC), kudzvanya kwakasiyana kunoshandiswa kutarisisa kuramba kwemhepo kwevateveri, mafirita, uye maducts, nekudaro optimize mashandiro ehurongwa uye kuderedza kushandiswa kwesimba. Saizvozvo, mukugadzirwa kweoiri negesi, kurapwa kwemvura, uye maindasitiri emishonga, kusiyanisa kuyerwa kwekuyerwa kwakakosha pakutarisa kuyerera kwemvura, sefa, uye kuita kwepombi, zvichibatsira kuchengetedza zvakajairwa mashandiro ehurongwa uye kudzivirira njodzi dzinogona kuitika.
Differential pressure transmitters ndiyo yakakosha maturusi ekuzadzisa ichi chinangwa. Vanogona kushandura mutsauko wekumanikidzwa kwemuviri kuita masaini emagetsi, ayo anogona kuzoshandiswa pakutarisa nekudzora zvinangwa. Nekushandisa zvinhu zvinonzwa kudzvanyirira zvakaita semadiaphragms, strain gauges, kana piezoelectric crystals, madhiraivha anosiyanisa anoyera nemazvo misiyano yekumanikidza uye anoburitsa masaini anobuda e4-20 mA kana 0-10 V. Aya masaini anogona kuendeswa mberi kune dashboards, kutora data. masisitimu, kana masisitimu ekudzora ekutarisa-nguva chaiyo uye kugadzirisa.
Izvo zvinoshandiswa zvekusiyanisa kuyera kudzvinyirira zvakakura. Izvo hazvibatsire chete kuve nechokwadi chekushanda kwakachengeteka kwemidziyo yemaindasitiri nemaitiro, kudzivirira kudzvanya uye njodzi dzine hukama asi zvakare inovandudza kushanda kwesimba uye kunaka kwechigadzirwa kuburikidza nekuita kwakagadziridzwa. Muindasitiri yemishonga, kuyera kudzvanywa kunopa huchokwadi hwekuvirisa uye kusefa maitiro, kuve nechokwadi chekuti chigadzirwa chekupedzisira chinosangana nezvinodiwa uye kuchengetedza kuvimba kwevatengi mumhando. Naizvozvo, kubva pamaonero ekuchengetedza, kugona, uye kuvimbiswa kwemhando, kudzvanywa kwekusiyanisa uye kuyerwa kwayo zvinhu zvakakosha zvemazuva ano maindasitiri uye ekutengesa zviitiko.
Zvishandiso zveDifferential Pressure Transmitters
Differential pressure transmitters zvinhu zvakakosha zveindasitiri otomatiki. Nekunyatsojeka kwavo uye kugadzikana, vanoita basa rakakosha mumaindasitiri akasiyana senge petrochemicals, kugadzirwa kwemagetsi, simbi, kurapwa kwemvura, chikafu nezvinwiwa, nemishonga. Zvishandiso izvi zvinonyanya kushandisa misimboti yemuviri, senge Bernoulli equation uye static pressure musimboti, kuyera kuyerera, nhanho yemvura, uye chimiro chemafirita, nekudaro ichipa yakakosha data kutsigira kugadzirwa nekutarisa maitiro.
Kuyerera kuyerwa inzvimbo huru yekushandisa yekusiyanisa kudzvanywa ma transmitters. Nekuyera mutsauko wekumanikidzwa unogadzirwa kana mvura ichiyerera nemuchina wekupuruzira, mwero wekuyerera kweoiri, gasi rechisikigo, chiutsi, uye zvimwe zvinwiwa zvinogona kuverengerwa nemazvo. Uye zvakare, mutsauko wekudzvanya madhiraivha aratidza kukosha kwawo muyero yemvura kuyerwa, kunyatso tarisisa hurefu hwemvura mumatangi ekuchengetera, boilers, uye mareactor, izvo zvakakosha pakuona kuchengetedzwa kwekugadzirwa uye kushanda zvakanaka.
Sefa yekutarisa ndeimwe yakakosha application. Differential pressure transmitters inoratidza kana sefa yakavharwa nekuona shanduko mumutsauko wekumanikidza pamberi uye mushure mesefa, nekudaro kuve nechokwadi chekushanda kwakajairika kwehurongwa. Kunze kweaya mashandisirwo chaiwo, mutsauko wekudzvanya ma transmitters anoshandiswawo zvakanyanya kutarisa kubuda kwepombi, kuita kwepombi, uye chimiro chemavharuvhu. Nekutarisa shanduko mukusiyana kwekumanikidza, ivo vanopa yakavimbika data tsigiro yekuchengetedza inoshanda system inoshanda.
Differential pressure transmitters inoitawo basa rakakosha mukutarisa kwezvakatipoteredza, kunyanya mukutarisisa mhando yemhepo. Nekuyera mutsauko wekumanikidza pakati penzvimbo dzakasiyana mumhepo, zviridzwa izvi zvinokwanisa kuverenga kumhanyisa kwemhepo uye vhoriyamu, zvichibva zvatarisa kuunganidzwa kwezvinhu zvakaita sePM2.5 nePM10, uye magasi akaita seSO2 neNO2. Pamusoro pezvo, ivo vanoita basa rakakosha mukutarisa kuburitswa kwemaindasitiri, kubuda kwemotokari, uye mukati memhepo mhando.
Mukutarisa kwekuchenesa imba, mutsauko wekudzvanya dhizaini unova nechokwadi chekuti hutsanana hwemhepo hunosangana nezviyero nekutarisa mutsauko wekumanikidza mukati medzimba dzakachena, zvakakosha pakutonga kwemhando mumaindasitiri emishonga, zvemagetsi, uye zvekudya. Pamusoro pekutarisa kwemhando yemhepo, aya ma transmitters anoshandiswawo mukutarisa kwemhando yemvura, hunyoro hwevhu, uye mamiriro ekunze emamiriro ekunze, zvichiratidza kuita kwavo kwakasiyana-siyana mumunda wekutarisa kwezvakatipoteredza.
Nekuda kwekuyerwa kwavo kwepamusoro (kusvika 0.1% -0.5%), kugadzikana kwakanyanya kwenguva refu, uye kureba kwekushandisa, zvakasanganiswa nekureruka kwekugadzika nekugadzirisa, mutsauko wekudzvanya madhiraivha ave maturusi akakosha mukutarisa kwezvakatipoteredza. Sezvo ruzivo rwekuchengetedzwa kwezvakatipoteredza ruchiwedzera, zvinotarisirwa kuti mutsauko wekudzvanya vanotumira uchaona mashandisirwo akafara mune ramangwana. Nekufambira mberi kwetekinoroji, kuita kwavo kuyerwa uye chiyero chekushandisa zvinotarisirwa kuwedzera kuwedzera, zvichipa rutsigiro rwakanyanya uye rwakavimbika data rekuchengetedza nharaunda.
Kuverenga Differential Pressure
Kuverengera kusiyanisa kudzvanywa inhanho yakakosha mumaindasitiri nekutengesa mashandisirwo, kunyanya mukuyeresa kuyerwa, kuyerwa kwemvura, uye kutarisisa mafirita. Kudzvinyirirwa kwakasiyana, mutsauko wekumanikidza pakati pemapoinzi maviri mukati mehurongwa, ipfungwa huru yemuviri. Yayo yekuverenga fomula iri nyore asi inoshanda: kusiyanisa kudzvanywa (Pd) yakaenzana neiyo yakakwira side pressure (Ph) minus yakaderera side pressure (Pl), uye inogona kuratidzwa muzvikamu zvakasiyana sePascal (Pa), mapaundi pa square inch (PSI). ), kana kubhawa.
Kuverenga mutsauko kudzvanywa kunosanganisira akati wandei matanho akakosha: chekutanga kugadzirira, kuve nechokwadi chekumisikidza kwakaringana uye kubatana kweiyo inosiyanisa kumanikidza transmitter; chinotevera kuita calculation, kuwana mhedzisiro kuburikidza nemusiyano wekumanikidza formula; pakupedzisira, kushandura mayunitsi sezvinodiwa. Semuenzaniso, kana system yakakwira side pressure iri 100 PSI uye yakaderera side pressure iri 50 PSI, ipapo mutsauko wekumanikidza i50 PSI.
Iko kurongeka kwekuyerwa kwekuyeresa kunokonzerwa nezvinhu zvakasiyana-siyana, zvinosanganisira kunyatsojeka kwe sensor, kubuda kunogona kuitika, shanduko yekushisa kwezvakatipoteredza, uye vibrations. Uyezve, zvichienderana nekushandiswa, kune marudzi akasiyana-siyana ekusiyanisa pressure transmitters, akadai se capacitive, piezoresistive, uye piezoelectric, imwe neimwe inokodzera kuyera kwakasiyana nharaunda uye zvinodiwa.
Iyo yekushandiswa kwemhando yekudzvinyirirwa kwakakura zvakanyanya, haina kuganhurirwa kune yekutarisa kuyerera, nhanho yemvura, uye mafirita, asi zvakare inosanganisira kudzvinyirira kutonga pakati pedzimwe nzvimbo. Kuyera kwakaringana kudzvanyirira kuyerwa kwakakosha kuti uve nechokwadi chekushanda kwakanaka kwemaindasitiri maitiro, kuvandudza mashandiro emidziyo, uye kuve nechokwadi chekuchengetedza mukugadzirwa. Naizvozvo, kunzwisisa misimboti yekusiyanisa kudzvinyirirwa, nzira dzekuverenga, uye basa rayo mukushandisa kwakasiyana hunyanzvi hwakakosha uye hwakakosha kune mainjiniya nevashandi vehunyanzvi.
