Ngesikhathi esifanayo, lapho usebenzisa ama-valve amaningana, kuyadingeka ukunaka umyalelo wokusebenza futhi uhambisane nenqubo yokukhiqiza. 10. Uma uvula i-valve yesayizi enkulu nge-valve yokudlula, uma umehluko wokucindezela phakathi kweziphetho ezimbili ukhulu kakhulu, i-valve yokungena kufanele ivulwe ukuze ishintshe ukucindezela futhi i-valve yokusabalalisa kufanele ivulwe futhi. 11. Uma uthola ibhola lengulube (idivayisi), i-valve yesango kuyo kufanele ivuleke. 12, ukusebenza kwe-valve yesango, i-valve yokumisa, i-valve yokumisa, i-disc valve ivuliwe noma ivaliwe kuphela, akuvunyelwe ukulawula. 13, ukusebenza kwe-valve yokumisa, i-valve yokumisa kanye nesixhumanisi se-valve yepuleti, lapho ivaliwe noma ivulekele endaweni engaguquki ephezulu noma indawo ephansi efile, kufanele ijikeleze indingilizi engu-1/2 ~ 1. Iphaneli yokulawula amavalvu kagesi entsha ehlakaniphile Isingeniso esifushane Iphaneli yokulawula yamavalvu kagesi emodular ehlakaniphile ye-DSM isebenzisa ubuchwepheshe obuthuthukisiwe bokucutshungulwa okuncane, i-IC chip edidiyelwe kakhulu kanye nezingxenye zayo zokuphuma kwamandla empilo ende yesevisi. Yamukela isignali yedatha yokulungiswa kwe-DC4~20mA ukusuka kudeshibhodi kanye nesignali yokulawula indawo yevalvu ye-DC4~20mA yesixhumi sikagesi esingaphezulu nesingaphansi (noma isignali yedatha "yezintambo ezintathu" yesiphikisa). Khipha amasiginali wedatha "evuliwe" kanye "nokuvalwa" ukuze uqedele ukulawula nokulungiswa kwedigri yokuvula i-valve. Iphaneli yokulawula ivalvu kagesi ye-DSM ehlakaniphile, enokusetha idatha, ekhombisayo, ukuma kwayo, ukuphenduka kwemoto ukuze uvule ukugcinwa, unqamule umbiko kanye nokulinganiswa kwensimbi ye-valve neminye imisebenzi ethuthukisiwe. Ukusebenza okushelelayo nokunembile kwe-valve, i-valve yokungena kanye nesakhiwo sokulungiswa kwe-diaphragm. Ingasetshenziswa kabanzi ekukhiqizeni amandla, imboni ye-metallurgical, uwoyela ongahluziwe, imboni yamakhemikhali nezinye izimboni. Iphaneli yokulawula ivalvu kagesi ehlakaniphile ye-DSM ingasetshenziswa hhayi kuphela kuma-actuator e-AC motor esigaba esisodwa (njenge-DKJ ne-DKZ kagesi), kodwa futhi kuma-actuator e-AC motor ezigaba ezintathu namadivayisi kagesi. Iphaneli yokulawula i-valve kagesi ye-DSM ehlakaniphile ehlakaniphile enokuhlanganiswa kwevalvu kagesi yendabuko, ekutholakaleni, ukwethembeka, ukunemba nezinye izici zingathuthukiswa izikhathi ezimbalwa, ngenxa yokuthuthukisa nokuthuthukisa i-actuator kagesi endala ilethe ubungqabavu obusha. Izici eziyinhloko: Ukulungiswa okuhlakaniphile: Lapho ulungisa "zero" kanye "nokugcwele" kwedigri yokuvula indawo ye-valve kanye ne-voltage ephumayo yendawo ye-valve, asikho isidingo sokulungisa i-resistor, asikho isidingo sokusebenzisa ithuluzi lokuhlola elijwayelekile ukuphatha. ukuphuma ukulungisa okuyinkimbinkimbi, udinga kuphela ukucindezela ukhiye wokusebenza kanye ezingxenyeni ezithile "zokuvala" kanye "nezivulekile" ze-valve, bese ukusetha okusha kwesigaba kulungiswa okuzenzakalelayo nokunembile ku-0-100% kanye ne-DC4-20mA. Idatha ingasethwa imingcele eyinhloko yendawo ye-valve electrodynamic, ukushajwa okuncane, ukusebenza okuzinzile, ukunemba okuphezulu. Vula isiqondiso ngokuthanda kwakho: Lapho ushintsha indlela yokuvula ye-valve kanye nemodi yesenzo se-valve, ingaqedwa ngokuvumelana nokusetha ukhiye wokusebenza ngaphandle kokudiliza zonke izintambo. Ibanga elivundlile elihlakaniphile: lingavimbela ukungqubuzana noma isimo "somthelela", sithuthukise ukunemba. Umsebenzi we-alamu wokulawula iphutha: Uma i-actuator yehluleka, umsebenzi we-alamu wokulawula iphutha lesistimu ehlakaniphile ungalawula iphutha ngokuzenzakalelayo futhi ubike, okubonisa iphutha le-actuator nokumaka ngokunembile isimo sokusebenza se-actuator. Ngokwezimo ezihlukene zamaphutha, kukhombisa ukuthi izinhlobo ezahlukene zezinhlelo ze-alamu zizonciphisa isikhathi esidingekayo ukuze kutholwe amaphutha ekhasimende futhi kubuyisele i-actuator ekusebenzeni okujwayelekile ngokushesha okukhulu. Ukugcinwa komehluko wesigaba esizenzakalelayo: Ngaphambi kokufakwa kwezintambo zesayithi, qinisekisa ukuthi ulayini ongathathi hlangothi wezigaba ezintathu ze-AC onikezwe i-actuator ufanelekile, ngoba uma ulayini ongathathi hlangothi ungalungile, kulula ukuvela ukujikeleza kwemoto okungalungile, ngaleyo ndlela kulimaze i-valve ne-actuator. . Manje amakhasimende angakwazi ukuqeda ngokuphelele lokhu kucindezeleka, izintambo akufanele zicatshangelwe lapho inkinga yomugqa womlilo ongathathi hlangothi. Uma umehluko wesigaba sokuhlanganisa izintambo ungasebenzi, isilawuli sokuvumelanisa isigaba sizolungisa ngokuzenzakalelayo umehluko wesigaba ukuze siqinisekise ukuthi i-valve isetshenziswa ngokuvumelana nesiqondiso somyalo. Okusho ukuthi, lapho i-actuator ithola umyalelo ovulekile, izohlala ijikeleza ngokuvumelana nendawo evulekile ehlelwe kusengaphambili, futhi ngeke isebenze ngokuphambene ngenxa yokushintshwa komugqa ongathathi hlangothi. Ukugcinwa okungavamile: Ukuvikelwa kwe-motor overcurrent: Lapho injini ye-actuator isebenza, i-DSZH220 izomisa injini ngokuzenzakalelayo ngenxa yezizathu ezihlukahlukene ezibangela ukuba injini ibe nokudlulele. Ukugcinwa kokuhlehla ngokushesha: Uma i-actuator iqala ukuzungezisa ohlangothini olulodwa, isibonelo, indawo yokuvula i-valve isetshenzisiwe. Uma umyalo wokuvala ama-valve wamukelwe, ilogic yokulawula yangaphakathi ye-actuator ingase ibambezeleke isikhathi esimisiwe ngaphambi kokuthi kuqaliswe umyalo wokuvala ama-valve. Lobu buchwepheshe buzonciphisa umthelela we-motor current futhi bukhulise impilo yesevisi yezingxenye zamandla, kuyilapho kugwema umthwalo womthelela esihlalweni se-valve, ibhokisi lokunciphisa kanye nezinye izisetshenziswa zokuhambisa ngomshini ezingase zidale umonakalo, ngaleyo ndlela zigcine injini ngendlela efanele. Ukugcinwa kwepulaki ye-valve: Uma i-actuator ingakwazi ukususa i-torque edingekayo ekusebenzeni kwe-valve, imibandela yangaphambili yepulaki ye-valve ikhona. Lapho i-actuator ithola isignali yokuqala ukuvula noma ukuvala, uma i-valve ibambekile, ngesikhathi esisethiwe futhi kungekho ukuma, isakhiwo sangaphakathi sesekethe yamandla sizophula iphuzu lokuxhumana elihambisanayo, ukuphazamisa okuphoqelekile ukuphazamisa ukusebenza kwe-actuator, Ngesikhathi esifanayo, isistimu ye-alamu ehambisanayo, ngaphezu kwesignali yedatha ingabuye ithunyelwe nge-RS485. Idatha ingasethwa lapho isignali yokufaka inqanyulwa ukubika nokuvikela. Khetha amadivaysi okugcina angalahleki okufunda bhala, kulula ukushintsha amapharamitha ayinhloko, cisha amandla okugcina isikhathi eside. Ukuguqulwa okuzenzakalelayo/okwenziwa ngesandla ngaphandle kokuphazanyiswa, ikhono elihle lokulwa nokuphazamiseka. Ukusebenza okulula: opharetha unemisebenzi eminingi eyinkimbinkimbi, kepha ukwakheka kwangaphakathi kwesoftware kamakhalekhukhwini kukushiye "ukuphazamiseka" kuwe, "ukulula" kukhasimende, okwenza ukuthi ukusebenza komshini womuntu kube lula futhi kulula. ukufunda. (I-actuator ye-AC220V motor ilawulwa ngokugcwele, futhi i-actuator ye-AC380V motor idinga ukwengeza indlela yokushayela amandla ye-AC380V)
