Ibinyugunyugu biroroshye, bito, kandi byoroshye kurenza ubundi bwoko bwigenzura, bituma bahitamo neza kugenzura imigendekere yimikorere myinshi. Ibinyugunyugu bisanzwe byifashishwa muburyo bwo gufungura / gufunga porogaramu, kandi bikwiranye nuru ruhare. Ariko, mugihe cyo kugenzura imigendekere muri sisitemu ifunze-loop, abajenjeri bamwe babona ko bitemewe.
Ikinyugunyugu kinyugunyugu gikoresha disiki izunguruka kugirango igenzure imigendere inyuze mu muyoboro. Disiki irashobora gukoreshwa binyuze muri dogere 90, kubwibyo rimwe na rimwe byitwa ko ari kimwe cya kane. Mubisanzwe, bikoreshwa mugihe harebwa ubukungu. Iyo gufunga gukenewe bisabwa, ikinyugunyugu kinyugunyugu hamwe na kashe yoroshye ya elastike hamwe na / cyangwa disiki isize irashobora gukoreshwa mugutanga imikorere isabwa. Umuvuduko mwinshi wibinyugunyugu (HPBV) -kubiri kabiri ya offset ya valve-ubu ni inganda zinganda zo kugenzura ibinyugunyugu kandi ikoreshwa cyane mugucunga ibintu. Bakora neza kubisabwa hamwe nigitutu gihoraho kigabanuka cyangwa gahoro gahoro.
Ibyiza bya HPBV birimo inzira igororotse binyuze munzira, ubushobozi buhanitse, hamwe nubushobozi bwo kunyura byoroshye itangazamakuru rikomeye kandi ryiza. Igiciro cyo kwishyiriraho mubisanzwe ni gito mubwoko bwose bwa valve, cyane cyane NPS 12 na valve nini. Ugereranije nubundi bwoko bwa valve, inyungu zabo ziyongera cyane iyo ubunini burenze santimetero 12.
Bashobora gutanga imikorere myiza yo gufunga mubushyuhe bwubushyuhe, kandi bagatanga ibishushanyo mbonera byumubiri bitandukanye, harimo ubwoko bwa wafer, ubwoko bwa lug na flange ebyiri. Biroroshye cyane kurenza ubundi bwoko bwa valve kandi biroroshye. Kurugero, santimetero 12 ANSI Icyiciro cya 150 icyiciro cya kabiri cya flange igizwe numupira wumupira ipima ibiro 350 kandi ifite imbona nkubone ya santimetero 13.31, mugihe ihwanye na santimetero 12 ya lug butterfly valve ipima ibiro 200 gusa na face-to- ibipimo byo mumaso ya santimetero 3.
Ibinyugunyugu bifite aho bigarukira bituma bidakwiriye kugenzurwa neza muri porogaramu zimwe. Ibi birimo ubushobozi buke bwo kugabanuka ugereranije numupira wumupira, hamwe na cavitation nini cyangwa flashing potential.
Kuberako ubuso bunini bwa disiki bukora nka leveri kugirango ikoreshe imbaraga zingirakamaro ziciriritse zitembera kuri shitingi, ibinyabiziga byikinyugunyugu bisanzwe ntibikoreshwa mubikorwa byumuvuduko mwinshi. Niba aribyo, ingano noguhitamo kwa actuator biba ingirakamaro.
Rimwe na rimwe bibaho ko ikinyugunyugu kigenzura ikinyugunyugu kirenze urugero, bizagira ingaruka mbi kumikorere. Ibi birashobora guterwa no gukoresha imiyoboro ingana nini, cyane cyane ikinyugunyugu kinini. Irashobora kongera uburyo bwo guhinduka muburyo bubiri. Mbere ya byose, kurenza urugero bizana inyungu nyinshi kuri valve, bityo bikabura guhinduka muguhindura umugenzuzi. Icya kabiri, indanga nini zishobora gukora cyane mugukingura kwa valve yo hepfo, mugihe gufunga kashe ya kinyugunyugu bishobora kuba binini. Kuberako kubwinyongera ya valve yiyongereye, valve nini cyane izabyara impinduka nini zitagereranywa. Iyi phenomenon izakabya cyane inzira ihindagurika ijyanye na zone yapfuye kubera guterana amagambo.
Abashiraho code rimwe na rimwe bakoresha ibinyugunyugu kubera impamvu zubukungu cyangwa guhuza nubunini bwatanzwe, tutitaye kubyo bugarukira. Hariho uburyo bwo kugenzura ikinyugunyugu kugirango wirinde kunyunyuza imiyoboro, ishobora kuganisha ku kugenzura nabi.
Intambamyi nini ni uko uburyo bwiza bwo kugenzura ibintu butagutse nkubunini bwo guhagarara cyangwa umupira ugabanijwe. Ibinyugunyugu muri rusange ntabwo bikora neza hanze yo gufungura hafi ya 30% kugeza 50%.
Mubisanzwe, iyo kugenzura loop ikora muburyo bumwe kandi inyungu yunguka yegereye 1, ikizunguruka kiroroshye kugenzura. Kubwibyo, inyungu yunguka ya 1.0 ihinduka intego yo kugenzura neza, kandi urwego rwemewe ni 0.5 kugeza 2.0 (intera 4: 1).
Imikorere nibyiza mugihe ibyinshi byunguka biva mubigenzuzi. Menya ko muburyo bwo kunguka kumurongo wa 1, inyungu zikorwa ziba nyinshi mukarere kari munsi ya 25% ya stroke ya valve.
Inyungu y'ibikorwa isobanura isano iri hagati y'ibisohoka nibihinduka. Inkoni aho inyungu yunguka ikomeza hagati ya 0.5 na 2.0 nuburyo bwiza bwo kugenzura valve. Iyo inyungu yunguka itari murwego rwa 0.5 kugeza 2.0, imikorere mibi idahwitse hamwe no guhungabana bidashoboka.
Iyo valve ifunze kugirango ifungure, igishushanyo cyibinyugunyugu kigira ingaruka zikomeye kumugezi wa valve. Disiki ifite ijanisha rihwanye irashobora kwishura neza igabanuka ryumuvuduko uhinduka nigipimo cyimbere. Kuringaniza ijanisha imbere bizatanga umurongo wo kwishyiriraho kugirango uhindure igitutu, nibyiza. Igisubizo nukuri guhinduka umwe-umwe hagati yumuvuduko wikigereranyo na valve stroke.
Vuba aha, ibinyugunyugu birashobora gukoresha disiki ifite ijanisha ringana. Ibi bitanga uburyo bwo kwishyiriraho ibisubizo mubikorwa byo kwishyiriraho inyungu murwego rusabwa rwa 0.5 kugeza kuri 2.0 hejuru yingendo nini. Ibi bizanoza cyane kugenzura ibicuruzwa, cyane cyane murwego rwo hasi rwurugendo.
Igishushanyo gitanga igenzura ryiza, hamwe ninyungu zemewe zingana na 0.5 kugeza kuri 2.0 kuva hafi 11% zifungura kugeza 70%, kandi urwego rwo kugenzura ruri hafi inshuro eshatu ugereranije nubusanzwe busanzwe bukora ibinyugunyugu (HPBV) bingana. Kubwibyo, ibice bingana na disiki itanga muri rusange inzira yo guhinduka.
Ibinyugunyugu bifite ibinyuranyo bingana biranga ijanisha, nka disiki yo kugenzura disiki, nibyiza kubikorwa bisaba gukora neza kugenzura neza. Hatitawe ku guhungabanya inzira, birashobora kugenzurwa hafi yintego yashyizweho, bityo bikagabanya guhinduka.
Niba ikinyugunyugu kidakora neza, gusa usimbuze valve nubunini bukwiye kugirango ukemure ikibazo. Kurugero, isosiyete ikora impapuro ikoresha ibinyugunyugu bibiri binini cyane kugirango igenzure ikurwaho ryamazi. Imyonga yombi ikora munsi ya 20% yubwonko, bigatuma habaho gutandukana kwa 3.5% na 8.0%. Ibyinshi mubuzima bwabo bwa serivisi bikoreshwa muburyo bwintoki.
Babiri bafite ubunini bukwiye NPS 4 Fisher Control-Disk ibinyugunyugu hamwe na digitale ya digitale. Umuzenguruko urimo gukora muburyo bwikora, uburyo bwo guhindura imikorere ya valve ya mbere bwiyongereye kuva kuri 3.5% bugera kuri 1,6%, kandi uburyo bwo guhindura imikorere ya valve ya kabiri bwiyongereye kuva kuri 8% bugera kuri 3.0%, nta guhinduranya bidasanzwe.
Umuvuduko ukabije wamazi no kugenzura uburyo bwo gukonjesha mu ruganda rwibyuma byatumye habaho kudahuza ibicuruzwa byanyuma. HPBV yashyizwe muri Jiutai ntishobora kugenzura neza amazi nkuko bisabwa.
Uruganda rwizeye gushyiraho valve zishobora kugenzura neza inzira kandi ikeneye kugabanya ibiciro byo kwishyiriraho. Uruganda ruzakoresha amadorari 10,000 yo gusimbuza imiyoboro ya buri valve kugirango ihindure kuva HPBV ihindurwe imipira yumupira. Ahubwo, Emerson arasaba ko Control-Disk ya butterfly valve ihura nubunini bwa HPBV imbona nkubone.
Igikoresho cya Control-Disk cyageragejwe hamwe na kimwe muri icyenda HPBVs, kandi imikorere yacyo yujuje ibisabwa. Uruganda rwasimbuye HPBV 8 zisigaye mu gihe cyumwaka umwe, kandi buri HPBV yari ifite ibikoresho bya Control-Disk. Ibi byavanyeho icyifuzo cyo gusimbuza amadolari 90.000 $ kumipira yagabanijwe, kandi igiciro cyimipira cyiyongereyeho 25% ugereranije n’ibinyugunyugu.
Igenzura-Disiki zitanga igenzura neza kandi zifasha gukuraho impinduka mubicuruzwa byanyuma. Uruganda rukora ibyuma rugereranya ko gushyiraho icyenda cya Control-Disk bishobora kuzigama hafi miliyoni imwe y’amadolari y’Amerika ku mwaka.
Ugereranije nubundi bwoko bwa valve, HPBV hamwe numwanya wa digitale ifite igiciro cyambere cyo kwishyiriraho kandi irashobora gutanga urwego ruhagije rwo kugenzura mugihe ingano ari nziza. Bafite ubushobozi buke kandi ntarengwa bwo gutembera. Ikinyugunyugu kinyugunyugu gifite ijanisha ryingana ryibice byimbere bitanga amahirwe yo kwagura igenzura, risa na valve yisi cyangwa umupira wumupira, kandi ufata umwanya wa HPBV gusa.
Mugihe uhitamo valve, cyane cyane HPBV, menya neza ko ari ingano ikwiye, bitabaye ibyo irashobora kugenzurwa nintoki nicyumba cyo kugenzura. Ni ngombwa kandi gusuzuma ubwoko bwa valve, ibiranga imiterere, hamwe nubunini bwa valve butanga ubugari bwagutse kubisabwa.
Mark Nymeyer numuyobozi ushinzwe itumanaho ryamamaza kwisi yose kugenzura imigendekere ya Emerson Automation Solutions.
Ntabwo ari umushahara. Uru ni urukuta rw'ubuntu. Ntabwo dushaka kubangamira intego yawe yo kuza hano, ibi rero bizatwara amasegonda make.
