Ibinyugunyugu biroroha, bito kandi byoroshye kurenza ubundi bwoko bwigenzura, bituma uba amahitamo meza yo kugenzura imigendekere yimikorere myinshi. Ubusanzwe, ikinyugunyugu gisanzwe cyakoreshejwe muburyo bwikora kuri / kuzimya kandi birahagije kururu ruhare.Nyamara , abajenjeri bamwe babona ko bitemewe mugihe cyo kugenzura imigendekere ya sisitemu ifunze-izunguruka.
Indangantege zikinyugunyugu zikoresha disikuru zizunguruka kugirango zigenzure imigendere zinyuze mu miyoboro. Disiki isanzwe ikora dogere 90, bityo rero rimwe na rimwe bakitwa kwizengurutsa inguni.Ubusanzwe, zikoreshwa mugihe ubukungu bwatekerejweho. na / cyangwa disiki isize irashobora gukoreshwa mugutanga imikorere isabwa.Ibikorwa Byinshi Byibinyugunyugu Byibinyugunyugu (HPBVs) - cyangwa Double Offset Valves - ubu ni amahame yinganda kubikorwa byo kugenzura ikinyugunyugu kandi bikoreshwa cyane mugucunga ibintu.Bakora neza kubisabwa hamwe ugereranije igitutu gihoraho kigabanuka cyangwa buhoro buhoro inzira.
Ibyiza bya HPBV birimo inzira igororotse igororotse, ubushobozi buhanitse, hamwe nubushobozi bwo kunyuza itangazamakuru rikomeye kandi ryijimye byoroshye.Bisanzwe bafite igiciro gito cyashyizweho cyubwoko ubwo aribwo bwose bwa valve, cyane cyane muri NPS 12 nubunini bunini.Ibiciro byabo byiyongera cyane ugereranije nubundi bwoko bwa valve mubunini burenga santimetero 12.
Zitanga imikorere myiza yo gufunga hejuru yubushyuhe bugari kandi ziraboneka mubishushanyo bitandukanye byumubiri harimo wafer, lug na flaned ebyiri.Biroroshye cyane muburemere kandi biroroshye kurenza ubundi bwoko bwa valve.Urugero, ANSI ya 12-cm Icyiciro cya 150 cyikubye kabiri cyumupira wumupira gipima ibiro 350 kandi gifite uburebure bwa imbonankubone bwa santimetero 13.31, mugihe icyuma cya kinyugunyugu cya santimetero 12 gihwanye na kilo 200 gusa kandi gifite uburebure bwa santimetero 3 imbona nkubone.
Ibibabi by'ikinyugunyugu bifite aho bigarukira bituma bidakwiriye kugenzurwa neza na porogaramu zimwe.Ibyo birimo ubushobozi buke bwo kugabanuka k'umuvuduko ugereranije n'umupira w'amaguru w'isi ufite amahirwe menshi yo gutembera cyangwa guhumeka.
Kuberako ubuso bunini bwa disiki bukora nka leveri, ugakoresha imbaraga zingufu ziciriritse zitembera kuri shitingi ya drake, indangagaciro zikinyugunyugu zisanzwe ntizikoreshwa mubikorwa byumuvuduko mwinshi.Iyo biri, ingano ya actuator no guhitamo biba ingirakamaro .
Kugenzura ibinyugunyugu birashobora rimwe na rimwe kurengerwa, bishobora kugira ingaruka mbi kumikorere yimikorere.Ibyo bishobora guterwa no gukoresha umurongo ufite ubunini buringaniye, cyane cyane ububobere bwikinyugunyugu. valve yunguka byinshi, hasigara ibintu byoroshye guhinduka muguhindura umugenzuzi. Icya kabiri, valve nini irashobora gukora cyane mugukingura kwa valve yo hepfo, kandi guterana kashe birashobora kuba binini muri kinyugunyugu. hatanzwe ubwiyongere bwurugendo rwa valve, iyi phenomenon irakabya cyane inzira ihindagurika ijyanye no guterana amagambo.
Abadondora rimwe na rimwe bakoresha ibinyugunyugu kugira ngo babe ubukungu cyangwa bahuze ingano y'umurongo runaka batitaye ku mbogamizi zabo.Hariho uburyo bwo kurenza urugero rw'ibinyugunyugu kugira ngo wirinde gutobora imiyoboro, ishobora kuganisha ku kugenzura imikorere mibi.
Intambamyi nini ni uko uburyo bwiza bwo kugenzura ibintu butagutse nkubunini bwumupira cyangwa igice cyumupira cyagabanijwe.Ibibabi byikinyugunyugu ntibikora neza hanze yubugenzuzi bwa 30% kugeza 50%.
Mubisanzwe, umuzingo uroroshye kugenzura mugihe umugenzuzi wo kugenzura ukora muburyo bumwe kandi inyungu yunguka yegereye ubumwe. Kubwibyo, inyungu yibikorwa ya 1.0 iba intego yo kugenzura neza, hamwe nintera yemewe ya 0.5 kugeza 2.0 ( urwego 4: 1).
Imikorere nibyiza mugihe ibyinshi byunguka biva mubigenzuzi. Menya ko mugihe cyo kunguka umurongo wigishushanyo 1, inyungu zikorwa ziba nyinshi mukarere kari munsi ya 25% yingendo za valve.
Inyungu yibikorwa isobanura isano iri hagati yisohoka ryibikorwa no guhindura ibyinjira.Impanuka aho inyungu zikorwa ziguma hagati ya 0.5 na 2.0 ninzira nziza yo kugenzura kuri valve.Iyo inyungu yunguka itari murwego rwa 0.5 kugeza kuri 2.0, imikorere idahwitse na loop ihungabana rirashobora kubaho.
Igishushanyo cya disiki yikinyugunyugu gifite ingaruka zikomeye kumugezi wa valve nkuko valve igenda ifunze ikingura.Ibisobanuro bifite imiterere ihwanye nijanisha rirashobora kwishura neza ibitonyanga byumuvuduko bitandukana nigitemba. nibyiza.Ibisubizo nibisobanuro byukuri, umwe-umwe gutandukana hagati yingendo ningendo za valve.
Ibinyugunyugu byibinyugunyugu biherutse gushyiraho disiki zifite ijanisha ryingana zingana.Ibi bitanga uburyo bwo kwishyiriraho butuma inzira yo kwishyiriraho yunguka mugihe cyifuzwa cya 0.5 kugeza kuri 2.0 hejuru yimitsi yagutse.Ibi bitezimbere cyane kugenzura imiyoboro, cyane cyane murugendo rwo hasi.
Igishushanyo gitanga igenzura ryiza, hamwe ninyungu zemewe zingana na 0.5 kugeza kuri 2.0, kuva hafi 11% zifunguye kugeza kuri 70%, kwiyongera hafi inshuro eshatu murwego rwo kugenzura ugereranije nibisanzwe bikora cyane byikinyugunyugu (HPBV) bingana. Kubera iyo mpamvu , ibice bingana kwijana rya disiki zitanga muri rusange inzira yo hasi ihinduka.
Ibinyugunyugu bifite ikinyuranyo kiringaniye kiringaniye, nka valve-Igenzura-Disiki, nibyiza kubikorwa bisaba imikorere igenzura neza.Birashobora kugenzurwa hafi yintego yashizweho hatitawe kubihungabanya inzira, bikagabanya guhinduka.
Niba ikinyugunyugu kidakora neza, kubisimbuza gusa na valve nini ikwiye bizakemura ikibazo.Urugero, uruganda rwimpapuro rukoresha ububiko bubiri bwikinyugunyugu bunini kugira ngo rugenzure kuvanaho ububobere buke. ingendo, bivamo inzira ihinduka ya 3.5% na 8.0%, kimwe.Ubuzima bwabo bwose bumara muburyo bwintoki.
Babiri bafite ubunini bukwiye bwa NPS 4 Fisher Control-Disk ikinyugunyugu hamwe na digitale ya valve igenzurwa.Umuzingo ubu urimo gukora muburyo bwikora hamwe nuburyo bwo guhinduka kuva kuri 3.5% kugeza kuri 1.6% kuri valve ya mbere na 8% kugeza 3.0% kuri valve ya kabiri idafite icyaricyo cyose kidasanzwe.
Umuvuduko muke wamazi no kugenzura imigezi muri sisitemu yo gukonjesha ibyuma byatumye ibicuruzwa bitarangira bidahuye.Icyicaro cyenda cyashyizweho HPBV nticyashoboye kugenzura neza amazi nkuko bisabwa.
Uruganda rwashakaga gushyiraho indangagaciro zishobora kugenzura neza inzira kandi zikenewe kugirango hagabanuke ibiciro byo kwishyiriraho. Uruganda ruzakoresha amadorari 10,000 yo gusimbuza imiyoboro ya buri valve kugirango ihindurwe kuva HPBV ihindurwe n’imipira y’imipira. Ahubwo, Emerson arasaba ko hakoreshwa ikinyugunyugu cya Control-Disk. valve yujuje ibipimo-imbonankubone ya HPBVs y'ubu.
Igikoresho cya Control-Disk cyageragejwe hamwe na kimwe muri icyenda HPBVs zisanzwe kandi cyujuje ibyasabwaga. Uruganda rwasimbuye HPBV umunani zisigaye mu gihe cyumwaka umwe, buri kimwe gifite ibikoresho bya Control-Disk, bikuraho ibikenewe. gusimbuza amadolari 90.000 yo kuvoma kumipira yagabanijwe, kandi umupira wumupira ugura hafi 25% kurenza ikinyugunyugu.
Igenzura-Disiki zitanga igenzura neza kandi zifasha gukuraho impinduka mubicuruzwa byarangiye.Urusyo rugereranya ishyirwaho ryimyenda icyenda ya Control-Disk izigama amadolari miliyoni imwe buri mwaka.
Ugereranije nubundi bwoko bwinshi bwa valve, HPBVs hamwe na posisiyo ya digitale ifite ibiciro byambere byo kwishyiriraho kandi, iyo bingana neza, bitanga urwego ruhagije rwo kugenzura.Bifite ubushobozi buke kandi ntarengwa bwo gutembera. intera, isa nisi cyangwa imipira yumupira, hanyuma ufate umwanya gusa wa HPBV.
Mugihe uhitamo valve, cyane cyane HPBVs, menya neza ko ari ingano ikwiye, bitabaye ibyo irashobora kugenzurwa nintoki nicyumba cyo kugenzura.Ni ngombwa kandi gutekereza ku buryo bwa valve, ibiranga imiterere nubunini bwa valve, bizatanga intera nini yo kugenzura kuri i Porogaramu.
Mark Nymeyer numuyobozi ushinzwe itumanaho ryamamaza kwisi yose kuri Emerson Automation Solutions, ashinzwe kugenzura ibinyabiziga.
Ntabwo ari umushahara. Uru ni urukuta rwubuntu. Ntabwo dushaka kubona inzira yintego yawe hano, bisaba rero amasegonda make.
