Witondere guhitamo neza kwimyubakire muburyo bwo kubaka imiyoboro - Imiyoboro yo gutoranya ibyingenzi byingenzi byahagaritswe mukarere kayobora

Kwitondera guhitamo neza kwimyubakire muburyo bwo kubaka imiyoboro - Imfashanyigisho yo gutoranya imyanya yingenzi ya valve ahantu hagenzurwa Mu kubaka imiyoboro, indangagaciro zigira uruhare mu kugenzura amazi. Kubera imiterere nibikoresho bitandukanye, so valve yakozwe ntabwo ari imwe. Kugirango tumenye neza ko imiyoboro ishobora kugera ku ntera ishimishije, igiciro gito ndetse nubuzima burebure bwa serivisi, guhitamo neza kwingirakamaro ni ngombwa. Umuyoboro ufite ibikorwa bine byingenzi: gutangira no guhagarika urujya n'uruza rw'itangazamakuru; Hindura uburyo bwo hagati; Irinda gusubira inyuma cyangwa kugaruka kandi igenga cyangwa igabanya umuvuduko wamazi. Guhitamo kubaka imiyoboro ya sisitemu irashobora gutekerezwa ukurikije ubushyuhe, ubwoko buciriritse, ubushyuhe nibindi bintu. , kurugero, mumazu maremare yinyubako yumuriro hydrant valve igenzura valve igomba gukoreshwa ibimenyetso, ibi bijyanye no kumenya niba sisitemu yumuriro wumuriro nurufunguzo rwo gukoresha neza, mugihe sisitemu yo kugenzura umuriro wa hydrant sisitemu yashizwe kumurongo wa signal, kandi valve ifunguye kugirango yerekane hagati yubugenzuzi bwumuriro, kugirango byoroherezwe kugenzura imiyoborere, nubwo igiciro cyiyongereye, icyakora, Ikigereranyo cyishoramari muri sisitemu ya hydrant muri rusange kiracyari gito cyane, kandi gishobora gutuma umutekano rusange wa sisitemu ya hydrant, ikwiye gushorwa. Ubwoko bwa valve YAKORESHEJWE muri sisitemu yo kubaka inyubako igomba gutoranywa ukurikije ibiranga inyubako. Niba valve yakoreshejwe idakwiriye kuranga inyubako, umubare wibyago bishobora guhora bivuka. Guhitamo imyanya ya valve bizahindura byimazeyo imikorere nubuziranenge bwo kugenzura valve no kugenzura sisitemu. Nigute rero wahitamo umwanya wa valve neza kandi neza ni ngombwa cyane murwego rwo kugenzura. Amagambo shingiro: guhitamo imyanya yimyanya yubuyobozi muri progaramu nyinshi zo kugenzura, umwanya wa valve ni kimwe mubikoresho byingenzi. Kubisabwa runaka, niba ushaka guhitamo icyerekezo gikwiye (cyangwa cyiza), ugomba gutekereza kubintu bikurikira: 1) Ikibanza cya valve gishobora "gutandukana-gutandukanya"? Biroroshye kandi byoroshye gushyira mubikorwa "gutandukana"? Kugira imikorere "gutandukana" bivuze ko umwanya wa valve usubiza gusa urutonde rwibimenyetso byinjira (urugero, 4 kugeza 12mA cyangwa 0.02 kugeza 0.06MPaG). Kubwibyo, niba ushobora "kugabana", urashobora ukurikije ibikenewe nyabyo, ikimenyetso kimwe gusa cyo kwinjiza kugirango ugere kubigenzuzi bibiri cyangwa byinshi bigenzura. 2) Guhindura ingingo ya zeru nintera biroroshye kandi byoroshye? Birashoboka guhindura zeru no gutandukanya udafunguye umupfundikizo? Ariko, ni ngombwa kumenya ko rimwe na rimwe guhuza ibyo bishakiye bigomba kubuzwa kugirango wirinde ibikorwa bitari byo (cyangwa bitemewe). 3) Ni ubuhe buryo buhamye bwa zeru n'intera? Niba ZERO N'URURIMI BISHOBORA KUGENDANA N'IMPINDUKA MU GIHE CY'AGATEGANYO, VIBRATION, IGIHE, CYANGWA GUSHYIRA MU BIKORWA, POSITIONER VALVE AZAKENEWE GUSUBIZWA CYANE KUBONA URUGENDO RUKURIKIRA. 4) Umwanya wa valve ufite ukuri gute? Byiza cyane, kubimenyetso byinjiza, Ibice bya Trim ya valve (Ibice bya Trim, harimo ibishishwa, uruti, intebe ya valve, nibindi) buri gihe bigomba guhagarikwa neza mumwanya ukenewe, utitaye ku cyerekezo cyurugendo cyangwa kugenzura valve nuburyo umutwaro mwinshi wibice byimbere. 5) Ni ubuhe buryo bwiza bwo mu kirere busabwa na valve uhagaze? Nkumubare muto cyane wogutanga ikirere urashobora gutangwa kugirango wuzuze ibipimo bya ISA (ibipimo byubwiza bwikirere kubikoresho: ISA STANDARD F7.3) KUBURYO BWA AIR, RERO, KUBA POSITIONERS ZA AIR-MOBILIZED CYANGWA ELECTRIC-GAZ (VALVE) BIGOMBA KUBONA IBIKURIKIRA KOKO-ISI, BAGOMBA KUBA BASHOBORA KUBONA AMAFARANGA MAKE YUMUKARA, MOISITO N'AMavuta. 6) Ese kalibrasi ya zeru nintera bigira ingaruka kuri buriwese cyangwa birigenga? Niba bigira ingaruka kuri mugenzi we, zeru hamwe nintera bifata igihe kinini cyo guhindura, kuko tuner igomba guhinduranya inshuro ebyiri ibipimo byombi kugirango buhoro buhoro bigere kumiterere nyayo. 7) Ese umwanya wa valve ufite ibikoresho bya "Bypass" yemerera ibimenyetso byinjira gukora muburyo butaziguye? Iyi "bypass" irashobora rimwe na rimwe koroshya cyangwa gusiba kalibrasi ya Igenamiterere rya Acuator, nka: "Igenamiterere rya Benchset" na "Seat Load setting" ya actuator - ibi ni ukubera ko mubihe byinshi, ibimenyetso byindege byindege ya bamwe mubashinzwe kugenzura pneumatike. ihuye na "intebe yashyizweho" ya actuator neza kugirango ntayindi mikorere isabwa (mubyukuri, muriki gihe, imyanya ya Valve irashobora kuvaho burundu. Birumvikana ko niba byatoranijwe, noneho umwanya wa valve ushobora no gukoreshwa "kurengana" ibimenyetso bya pneumatike byerekana ibimenyetso bya pneumatike kubuyobozi). MUBYEREKEYE, hamwe na "bypass" rimwe na rimwe birashobora kandi kwemerera guhinduka cyangwa gufata neza umwanya wa valve kumurongo (nukuvuga, gukoresha ikibanza cya valve "bypass" kugirango umugenzuzi akomeze gukomeza imirimo isanzwe, atabanje guhatira umugenzuzi kumurongo ). 8) Niba imikorere ya valve positioner yihuta? Ikirere kinini Umuyoboro mwinshi (aho uhagarara wa valve uhora ugereranya ibimenyetso byinjira nurwego rwa valve kandi ugahindura ibisohoka ukurikije itandukaniro. Niba imyanya ya valve isubiza vuba kuri uku gutandukana, noneho umwuka mwinshi mwinshi mugihe cyumwanya), byihuse guhinduka Sisitemu INSHINGANO Kuri Gushiraho no gutwara ibintu bitandukanye - bivuze amakosa make ya sisitemu (lag) hamwe nubuziranenge bwiza bwo kugenzura. 9. urwego rwo hejuru rwunvikana kubisubizo byinshyi), nibyiza kugenzura imikorere. Ariko, hagomba kumenyekana ko ibiranga inshuro bigomba kugenwa nuburyo bukoreshwa bwikigereranyo aho kuba uburyo bwa teoretiki, kandi imyanya ya valve hamwe na actuator bigomba kurebwa hamwe mugihe cyo gusuzuma ibiranga inshuro 10) Ni ubuhe butumwa ntarengwa bwo gutanga ikirere bwa posisiyo ya valve? Kurugero, imyanya imwe ya valve ifite umuvuduko munini wogutanga ikirere cya 501b / muri (ni ukuvuga 50psi, lpsi = 0.07kgf / cm ≈ 6.865kpa), umwanya wa valve uhinduka imbogamizi kumasoko asohoka niba umukoresha yapimwe gukora ku gitutu kirenze 501b / muri. 11) Iyo igenzura rya valve na valve imyanya ikusanyirijwe hamwe igahuzwa, bite byimyanzuro yabo? Ibi bifite ingaruka zigaragara cyane kumiterere yubugenzuzi bwa sisitemu yo kugenzura, kubera ko uko imyanzuro ihanitse, niko yegereye umwanya wa valve igenzura ni ku gaciro keza, kandi ihinduka ry’imihindagurikire iterwa na Overshooting ya valve igenga irashobora kugenzurwa, kugirango ugabanye impinduka zigihe cyumubare wagenwe. 12) Niba ihinduka ryiza kandi ribi ryumwanya wa valve birashoboka? Inzibacyuho iroroshye? Rimwe na rimwe, iyi mikorere irakenewe. URUGERO, GUHINDUKA "KUGARAGAZA KUGARAGAZA-GUKORA VALVE HAFI" uburyo "" KUGARAGAZA IKIMENYETSO-VALVE GUKINGURA "UBURYO, URASHOBORA GUKORESHA VALVE POSItioner nziza kandi NIGATIVE IKIGANIRO. 13) Ni ubuhe buryo bukomeye imikorere yimbere no gufata neza umwanya wa valve? Nkuko twese tubizi, ibice byinshi, nuburyo bugoye imikorere yimbere imbere, amahugurwa menshi yo kubungabunga (gusana) abakozi, nibindi bikoresho byabitswe. 14) Ni ubuhe buryo buhoraho bwo gukoresha ikirere cya valve umwanya wa valve? Kubintu bimwebimwe byashizwemo, iyi parameter irakomeye kandi irashobora kuba imbogamizi. 15) Nibyo, ibindi bintu nabyo bigomba kwitabwaho mugihe cyo gusuzuma no guhitamo imyanya ya valve. Kurugero, Ibitekerezo bihuza guhuza umwanya wa valve bigomba kwerekana umwanya wibisebe; Mubyongeyeho, imyanya ya valve igomba kuba ikomeye kandi iramba, hamwe no kurengera ibidukikije no kurwanya ruswa, kandi byoroshye gushiraho no guhuza.
