Iphaneli entsha yokulawula ivalvu yombane ekrelekrele
Intshayelelo emfutshane
Iphaneli yokulawula ivalvu yombane ekrelekrele ye-DSM isebenzisa itekhnoloji ephuculweyo ye-micro-processing, i-chip ye-IC edityanisiweyo kakhulu kunye namacandelo ayo okuvelisa amandla obomi obude. Yamkela i-DC4 ~ 20mA isignali yedatha yohlengahlengiso ukusuka kwideshibhodi kunye ne-DC4 ~ 20mA isignali yokulawula indawo yevalvu ye-actuator yombane ephezulu nangaphantsi (okanye "i-wire-three-three" isignali yedatha ye-resistor). Thumela ngaphandle "kwi" kunye "nokucima" iimpawu zedatha ukugqiba isidanga sokuvula ivalve kunye nohlengahlengiso. Iphaneli yokulawula ivalvu yombane ye-DSM ekrelekrele, ngokusetwa kwedatha, ebonisa, indawo, ukujika kwemoto ukujika ukugcinwa, ukuqhawula ingxelo kunye nokulinganisa isixhobo sevalve kunye neminye imisebenzi ephambili. Ukusebenza okugudileyo nokuchanekileyo kwevalve, ivalve yokungena kunye nesakhiwo sohlengahlengiso lwe-diaphragm. Ingasetyenziswa ngokubanzi ekuveliseni amandla, ishishini metallurgical, ioli ekrwada, ishishini imichiza kunye namanye amashishini.
Iphaneli yokulawula ivalvu yombane ekrelekrele ye-DSM ingasetyenziswa kungekuphela kwisigaba esinye se-AC motor actuators (ezifana ne-DKJ kunye ne-DKZ i-activators zombane zombane), kodwa nakwizigaba ezintathu ze-AC motor actuators kunye nezixhobo zombane. Iphaneli yokulawula ivalve yombane ye-DSM ekrelekrele enemodyuli kunye nokuhlanganiswa kwevalve yombane yemveli, ekufumanekeni, ukuthembeka, ukuchaneka kunye neminye imiba inokuphuculwa izihlandlo ezininzi, ukuphuculwa kunye nokuphucula i-actuator endala yombane izise amandla amatsha.
Iimpawu eziphambili:
Ukulungiswa okunengqondo: Xa ulungisa "i-zero" kunye "egcwele" yeqondo lokuvula indawo yevalve kunye nombane wokuphuma kwendawo yevalve, akukho mfuneko yokulungelelanisa isichasi, akukho mfuneko yokusebenzisa isixhobo sovavanyo oluqhelekileyo ukwenza uhlengahlengiso oluntsonkothileyo. , kufuneka ucinezele iqhosha lomsebenzi kanye kwindawo ethile "yokuvala" kunye "nokuvulwa" kwevalve, emva koko ukusetwa okutsha kwecandelo ngokuzenzekelayo kunye nokulungelelaniswa okuchanekileyo kwi-0-100% kunye ne-DC4-20mA.
Idatha inokusetwa iiparitha eziphambili zendawo ye-valve electrodynamic, i-overcharge encinci, ukusebenza okuzinzileyo, ukuchaneka okuphezulu.
Ulwalathiso oluvulekileyo ngokuthanda: Xa utshintsha indlela yokuvula i-valve kunye nemodi yesenzo se-valve, inokugqitywa ngokuhambelana nesitshixo sokumisela umsebenzi ngaphandle kokuqhawula yonke i-wiring.
Umgama othe tyaba obukrelekrele: unokuthintela ukungquzulana okanye imeko "yempembelelo", ukuphucula ukuchaneka.
Umsebenzi we-alarm yokulawula impazamo: Nje ukuba i-activator ingaphumeleli, inkqubo ehlakaniphile yokulawula impazamo i-alarm ingakwazi ukulawula impazamo ngokuzenzekelayo kunye nengxelo, ebonisa impazamo ye-actuator kunye nokuphawula ngokuchanekileyo imeko yokusebenza ye-actuator. Ngokweemeko ezahlukeneyo zeempazamo, kubonisa ukuba iintlobo ezahlukeneyo zeenkqubo ze-alamu ziya kunciphisa ixesha elifunekayo lokubona iimpazamo zabathengi kunye nokubuyisela i-actuator ekusebenzeni okuqhelekileyo ngokukhawuleza.
Ukugcinwa kokwahlukana kwesigaba esizenzekelayo: Ngaphambi kocingo lwesayithi, qinisekisa ukuba umgca ongathathi hlangothi wesigaba sesithathu se-AC amandla akhutshwe kwi-activator ifanelekile, kuba xa umgca ongathathi hlangothi ungalunganga, kulula ukubonakala ujikeleza ngokungafanelekanga i-motor, ngaloo ndlela uyonakalisa i-valve kunye ne-actuator. . Ngoku abathengi banokuphelisa ngokupheleleyo olu nxunguphalo, i-wiring akufanele ithathelwe ingqalelo xa ingxaki yomgca womlilo ongathathi hlangothi. Xa umahluko wesigaba se-wiring ungekho kulungelelwano, umlawuli wokulungelelaniswa kwesigaba uya kulungisa ngokuzenzekelayo umahluko wesigaba ukuqinisekisa ukuba i-valve iqhutywe ngokomyalelo womyalelo. Oko kukuthi, xa i-actuator ifumana umyalelo ovulekileyo, iya kuhlala ijikeleza ngokwendawo evulekileyo ebekwe kwangaphambili, kwaye ayiyi kusebenza kwicala elichaseneyo ngenxa yokutshintshwa komgca ongathathi hlangothi.
Ulondolozo olungaqhelekanga:
Ukukhuselwa kwe-Motor overcurrent: Xa i-actuator motor isebenza, i-DSZH220 iya kumisa ngokuzenzekelayo i-motor ngenxa yezizathu ezahlukeneyo ezibangela ukuba i-motor ibe ne-overcurrent.
Ukugcinwa kokuguqulwa ngokukhawuleza: Xa i-actuator iqala ukujikeleza kwicala elinye, umzekelo, indawo yokuvula i-valve iphunyeziwe. Ukuba umyalelo wokuvala ivalve ufunyenwe, ingqiqo yolawulo lwangaphakathi lwe-activator inokulibazisa ixesha elithile phambi kokuba umyalelo wokuvala uphunyezwe. Le teknoloji iya kunciphisa impembelelo yemoto yangoku kwaye yandise ubomi benkonzo yamacandelo amandla, ngelixa uphepha umthwalo wempembelelo kwisihlalo sevalve, ibhokisi yokunciphisa kunye nesinye isixhobo sokuhanjiswa komatshini kunokubangela umonakalo, ngaloo ndlela kugcinwe i-motor ngokufanelekileyo.
Ukugcinwa kweplagi yevalvu: Ukuba i-actuator ayikwazi ukukhupha i-torque efunekayo ekusebenzeni kwevalve, imiqathango yangaphambili yeplagi yevalve ikhona. Xa i-actuator ifumana isignali yokuqala ukuvula okanye ukuvala, ukuba i-valve ibambekile, ngexesha lokuseta kwaye akukho ndawo, isakhiwo sangaphakathi sesiphaluka samandla siya kuphula indawo yoqhagamshelwano ehambelanayo, ukunyanzeliswa kokuphazamisa ukusebenza kwe-actuator, ngexesha elifanayo, inkqubo ye-alamu ehambelanayo, ukongeza kwisignali yedatha ingathunyelwa ngaphandle nge-RS485.
Idatha inokusetwa xa isignali yegalelo ivaliwe ukunika ingxelo kunye nokhuseleko.
Khetha izixhobo zokugcina ezingenayo ilahleko zokufunda-bhala, kulula ukutshintsha iiparitha eziphambili, cima amandla okugcina ixesha elide.
Ukuguqulwa okuzenzekelayo / okwenziwe ngesandla ngaphandle kokuphazamiseka, isakhono esihle sokuchasana nokuphazamiseka.
Ukusebenza okulula: umqhubi unemisebenzi emininzi entsonkothileyo, kodwa ubume bangaphakathi besoftware yefowuni ephathwayo ikushiye "ukuphazamiseka" kuwe, "uncedo" kumthengi, okwenza ukuba umsebenzi wokutshintshiselana ngomatshini ulula kwaye kulula. ukufunda.
