Amakuru - Valve y'umupira ifite moteri: Ubuyobozi bwo gukora imashini zikora n'ikoreshwa ryayo

Valve y'umupira ifite moteri ni iki?

Valves z'umupira zifite moteri(bikunze kwitwaValves z'umupira w'amashanyarazi) zicaye aho valve zikoresha moteri zihurira n'izikoresha automatic control valves. Igishushanyo cyazo cy'ibanze gihuza icyerekezo cya kaneValve y'umupiraUburyo bukoresha icyuma gikoresha amashanyarazi, butuma habaho kugenzura neza amazi (amazi, imyuka, cyangwa ibitonyanga) hakoreshejwe ibimenyetso by'amashanyarazi. Bitandukanye na za valves z'intoki zisaba gukoreshwa aho zikorera, izi valves zikoresha ikoranabuhanga zihuza neza na sisitemu zo kugenzura imashini (ICS) kugira ngo zikore amabwiriza yo gufungura/gufunga cyangwa gutunganya neza inzira y'amazi—ni ingenzi cyane ku bikorwa aho ibikorwa by'abantu bidashoboka cyangwa biteje akaga.

Mu bunararibonye bwanjye, inyungu ikomeye ya valves z'umupira zikoresha moteri kurusha izindi valves zikoresha ikoranabuhanga (nk'imashini zikoresha amashanyarazi) ni umuvuduko wazo: moderi nyinshi zirangiza kuzunguruka kwa dogere 90 (zifunguye kugeza zifunze) mu masegonda 3.5 cyangwa munsi yayo, bigatuma ziba nziza cyane mu bikorwa bireba igihe nko kwitandukanya n'imiyoboro y'amashanyarazi.

Valve y'umupira ifite moteri

Isesengura ry'ibice by'ingenzi: Ni iki gituma bikora?

Nyuma yo gusesengura no kugerageza ibikoresho birenga 300 bya moteri bya valves, nabonye ibice bibiri bitavugwaho rumwe bigena imikorere n'igihe kirekire. Dore isesengura rirambuye rya buri kimwe, hamwe n'amahitamo y'ibikoresho n'ibiranga:

1. Iteranya ry'ibikoresho by'amashanyarazi

Actuator ni "ubwonko n'imitsi" bya valve—ihindura ibimenyetso by'amashanyarazi mu buryo bwa mekanike. Ibisobanuro by'ingenzi bigomba gushyirwa imbere (hashingiwe ku makuru y'ikibazo cyo mu murima) birimo:

•Ihuza ry'ibimenyetso byo kugenzura:Sisitemu nyinshi z’inganda zikoresha 4-20mA (mu bijyanye no guhindura imikorere ya analog) cyangwa ibimenyetso bya 0-10V, ariko ndakugira inama yo guhitamo actuators zifite support y’ibimenyetso bibiri kugira ngo zorohe.

•Urusobe rw'amatara:50-2000Nm ni ibisanzwe, ariko ntukarenze urugero: actuator ya 2000Nm ikoresha valve ntoya ya santimetero 2 ipfusha ubusa ingufu kandi yongera ibyago byo kwangirika. Urugero, umuyoboro wa santimetero 4 ukoresha amazi ukeneye gusa 150-200Nm.

•Igihe cyo Gusubiza na Sisitemu z'Ibikoresho:Sisitemu zo kugabanya ibikoresho (ubusanzwe ni verisiyo zo mu bwoko bwa worm cyangwa bevel) zigena umuvuduko—zigomba kugera kuri ≤3.5s kugira ngo zikore vuba (nk'ibipimo bya shimi). Irinde verisiyo za pulasitiki; verisiyo z'icyuma zimara igihe kirekire inshuro 3 mu bice bitigita cyane.

•Igipimo cy'Uburinzi:IP67 niyo ntarengwa ku bice byo hanze cyangwa bitose (urugero, inganda z'amazi yanduye). Ku nkengero z'inyanja, vugurura IP68 kugira ngo hirindwe kwangirika kw'amazi y'umunyu mu nsinga z'imbere.

2. Uburyo bwo gukoresha valve y'umupira

Igice cy'umuyoboro w'amashanyarazi n'ibice by'imbere bigira ingaruka zitaziguye ku kaga ko kuva kw'amazi no guhuza n'ibice by'amashanyarazi. Dore icyo ugomba kureba:

•Ibikoresho by'umubiri wa Valve:Icyuma kidashonga (316SS) ni cyo nkunda cyane mu bikoresho byangiza (imiti, amazi yo mu nyanja), mu gihe CF8M (ubwoko bwa 304SS) ikora ku bintu bidafite ingaruka mbi (amazi, umwuka ufunze). Ku bikoresho bikoresha ubushyuhe bwinshi (≥200℃), koresha Alloy C276—twayigerageje mu ruganda rutunganya ibintu ariko nta mpinduka na mba nyuma y’amezi 6 ikoreshwa buri gihe.

•Umupira uzenguruka:Guhinduranya 90° ni ibisanzwe, ariko hitamo hagati y’amazi yuzuye (amazi menshi asohoka, umuvuduko muto ugabanuka) cyangwa amazi make (igiciro gito, ni byiza ko amazi menshi asohoka neza). Urugero, amazi yuzuye ni ingenzi mu gukwirakwiza gazi karemano (kugira ngo hirindwe kwiyongera k’umuvuduko), mu gihe amazi make ahagije mu kugenzura amazi akonje ya HVAC.

•Igishushanyo mbonera cy'intebe:Intebe za PTFE ni nziza cyane ku bikoresho bifite umuvuduko muke kandi bidatera umwanda (bitanga umwuka ntarengwa uvamo nk'uko biteganywa na ANSI/FCI 70-2). Ku bijyanye n'umuvuduko mwinshi (≥1000psi) cyangwa ibyuma bitera umwanda, koresha intebe zikoresha icyuma kuva ku cyuma kugeza ku cyuma—twasimbuje intebe za PTFE n'iz'icyuma mu buryo bw'amazi yanduye yo mu bucukuzi bw'amabuye y'agaciro kandi twagabanyije kwangirika kw'ibifunga ku kigero cya 75%.

Ni gute Valve y'umupira ifite moteri ikora?

Ihame ry'imikorere rirasobanutse, ariko utuntu duto duto two gushushanya (nk'uduce duto two gutanga ibitekerezo) bigira itandukaniro rikomeye mu buryo bwo kwizerwa. Dore isesengura ry'intambwe ku yindi rishingiye ku buryo tubisobanurira abakiriya mu gihe cyo gutanga serivisi:

1. Kwakira ibimenyetso:Imashini ikoresha amashanyarazi ihabwa itegeko rivuye kuri PLC (Programmable Logic Controller) cyangwa DCS (Distributed Control System)—urugero, “ifunguye kugeza kuri 50% by’amazi” kugira ngo ikoreshwe mu gupima imiti.

2. Guhindura Torque:Moteri y'ikinyabiziga irazunguruka, maze agasanduku k'amashanyarazi kagabanya RPM kugira ngo gatange imbaraga zihagije zo kuzunguruka umupira (ntibipimishe moteri).

3. Uburyo bwo kugenzura imiterere y'amazi: Uburyo bwo gutanga ibitekerezo:Nyuma yo kugera aho intego iherereye, icyuma gikoresha amashanyarazi cyohereza ikimenyetso cya 4-20mA kuri icyuma gikoresha amashanyarazi (urugero, "50% byemewe ko bifunguye"). Iki gice kirinda gukurura cyane—imwe mu mpamvu zikomeye zitera amakosa mu mikorere ya sisitemu zidakurikiranwa.

• Ifunguye burundu:Umuyoboro w'imbere w'umupira uhuye neza n'umuyoboro, bigatuma amazi atemba neza (imiyoboro yuzuye ifite igabanuka ry'umuvuduko hafi ya zeru hano).

• Bifunze neza:Umupira uzenguruka dogere 90, ugafunga umuyoboro burundu—intebe za PTFE zikora umupfundikizo ukomeye kugira ngo wirinde ko amazi asohoka.

• Guhindura uburyo bwo kugenzura:Ku bijyanye na valve za V-port ball (zikoreshwa mu buryo bunoze nka farma CIP / SIP processes), umupira uzenguruka kuri 10-90° kugira ngo uhindure uburyo amazi agenda buhoro buhoro. Twigeze gukoresha ibi kugira ngo dukomeze kugira igipimo cya ± 0.5% cy'amazi ku murongo ukorerwamo inkingo—ni ingenzi cyane kugira ngo umubare w'inkingo urusheho kuba mwiza.
