Gusaba Ibisabwa hamwe na tekiniki ya tekinoroji ya sitasiyo yamashanyarazi (2)

Valve ikunze guhura no kunanirwa kumpanuro 10 zifatika, hepfo tuzavuga muburyo burambuye.
1 Kuki valve yaciwe igomba gufungwa bikomeye bishoboka?
Gabanya ibyangombwa bisabwa kugirango bishoboke, bishoboke, kashe ya kashe ya valve yamenetse ni mike, gabanya ingaruka birumvikana, ariko ntukambare kwihanganira, kwizerwa nabi. Kuva kumeneka kandi ntoya, gufunga no kwizerwa kabiri, kashe yoroheje yaciwe nibyiza kuruta kashe yaciwe. Nka fonctionnement yuzuye ultra-yumucyo igenga valve, ifunze kandi igashyirwa hamwe no kurinda imiti irinda kwambara, kwizerwa cyane, igipimo cyo kumeneka cya 10-7, yashoboye kuzuza ibisabwa na valve yaciwe.
2. Ni ukubera iki bidashobora gukoreshwa kashe ya kashe ya kabiri?
Ibyiza byimyanya ibiri ya valve spol nuburyo bwo kuringaniza imbaraga, kwemerera itandukaniro rinini ryumuvuduko, kandi ingaruka zidasanzwe ni uko ibice bibiri bifunze bidashobora kuba byiza icyarimwe, bikavamo kumeneka kwinshi. Niba ikoreshwa muburyo bwa artile kandi ku gahato kugirango uhagarike ibirori, biragaragara ko ingaruka atari nziza, kabone niyo yaba yarahinduye byinshi (nka kashe ya kashe ya kabiri), ntabwo byifuzwa.
3. Kuki byoroshye kunyeganyega mugihe imyanya ibiri yintebe iba ifunguye?
Kuri intangiriro imwe, iyo ikigereranyo gitemba ubwoko, valve ihagaze neza; Iyo imiyoboro ifunguye ifunze, ituze rya valve iba ikennye. Intebe yintebe ya kabili ifite ibice bibiri, icyuma cyo hepfo kiri mumigezi ifunze, icyuma cyo hejuru kiri mumugezi ufunguye, nuko, mumurimo muto wo gufungura, gutembera gufunga ubwoko bworoshye byoroshye gutera kunyeganyega kwa valve, iyi nimpamvu ituma imyanya ibiri yimyanya idashobora gukoreshwa kumurimo muto wo gufungura.
4, ni ubuhe buryo bugororotse bugenga imikorere yo guhagarika imikorere idahwitse, imikorere ya Angle stroke guhagarika imikorere nibyiza?
Inzira igororotse ya valve igororotse ni vertical trottling, kandi uburyo bwo gutambuka gutambuka no gusohoka mu muyoboro wa valve chambre bigomba gusubira inyuma, kugirango inzira itemba ya valve ibe ingorabahizi (imiterere nkubwoko bwa “S” ihindagurika). Muri ubu buryo, hari uturere twinshi twapfuye, dutanga umwanya wubushyuhe bwimvura, kandi mugihe kirekire, bitera kuziba. Icyerekezo cya Angle stroke valve itera ni icyerekezo gitambitse, ikigereranyo gitemba kandi gisohoka, kandi biroroshye gukuramo uburyo bwanduye. Mugihe kimwe, inzira itemba iroroshye, kandi umwanya wimvura uringaniye ni muto cyane, nuko Angle stroke valve ifite imikorere myiza yo guhagarika.
5, ni ukubera iki igiti kigororotse cyo kugenzura igiti cyoroshye?
Inzira igororotse igenga valve ikubiyemo ihame ryoroheje ryubukanishi: guterana kwinshi kunyerera, gutobora gato. Umuyoboro ugororotse uhagaze hejuru no kumanuka, gupakira ukanda gato, bizashyira uruti rwa valve ruziritse cyane, rutange itandukaniro rinini ryinyuma. Kubera iyo mpamvu, igiti cya valve cyagenewe kuba gito cyane, kandi gupakira bikoreshwa hamwe na coefficient ntoya yo gupakira PTFE ipakira, kugirango ugabanye inyuma, ariko ikibazo nuko igiti cya valve ari cyoroshye, cyoroshye kugorama , kandi gupakira ubuzima ni bugufi. Kugira ngo iki kibazo gikemuke, inzira nziza ni ugukoresha ingendo ya valve yingendo, aribwo bwoko bwa Angle stroke yubwoko bugenga valve, igiti cyacyo cya valve gifite umubyimba wikubye inshuro 2 ~ 3 kurenza igiti kigororotse, no guhitamo ubuzima burebure bwa grafite. , gukomera kwingirakamaro nibyiza, gupakira ubuzima ni birebire, torque yo guterana ni nto, itandukaniro rito.
6. Kuki gutandukanya itandukaniro ryumuvuduko wa Angle stroke valve nini?
Inguni yubwoko bwa valve yagabanije itandukaniro ryumuvuduko ni nini, kubera ko uburyo bwo muri plaque cyangwa plaque ya plaque bivamo imbaraga kuri rotation shaft torque ni nto cyane, kubwibyo, irashobora kwihanganira itandukaniro rinini ryumuvuduko.
7. Ni ukubera iki valve yikiganza yasimbuye icyicaro kimwe ninshuro ebyiri ariko ntigere kuntego zayo?
Umuyoboro wamaboko wasohotse mu myaka ya za 1960, wakoreshejwe cyane mu gihugu no hanze yacyo mu myaka ya za 70. Mu ruganda rwa peteroli rwatangijwe mu myaka ya za 1980, valve yikiganza yagize uruhare runini. Muri kiriya gihe, abantu benshi bizeraga ko valve yintoki ishobora gusimbuza icyicaro kimwe ninshuro ebyiri hanyuma igahinduka igisekuru cya kabiri cyibicuruzwa. Uyu munsi, ntabwo aribyo, icyicaro kimwe, icyicaro cyimyanya ibiri, icyuma cyamaboko gikoreshwa kimwe. Ibi ni ukubera ko valve yintoki itezimbere gusa uburyo bwo gutereta, gutuza no kubungabunga neza kuruta icyicaro kimwe, ariko uburemere bwacyo, ibipimo byo guhagarika no kumeneka bihuza na valve imwe yintebe ebyiri, nigute ishobora gusimbuza icyicaro kimwe kandi cyikubye kabiri? ? Rero, igomba gusaranganywa.
8. Ni ukubera iki ubuzima bwumurimo bwamazi yamazi aringaniye hamwe na reberi yikinyugunyugu na fluor itondekanye na diafragm valve?
Amazi yamazi arimo aside irike cyangwa alkali, bifite ruswa nyinshi kuri reberi. Kwangirika kwa reberi kurangwa no kwaguka, gusaza n'imbaraga nke. Ingaruka yo gukoresha ikinyugunyugu na diafragm valve ikurikiranye na reberi ni mbi. Ikigaragara ni uko reberi idashobora kwangirika. Nyuma ya reberi ya diaphragm ya valve imaze kunozwa kugirango irwanye ruswa ya fluor itondekanye na diaphragm valve, ariko diaphragm ya fluor itondekanye na diafragm valve ntishobora kwihagararaho no kumanuka no kumeneka, bikaviramo kwangirika kwa mashini, ubuzima bwa valve bugufi. Noneho inzira nziza ni ugukoresha amazi kugirango uvure umupira wumupira, urashobora gukoreshwa mumyaka 5 kugeza 8.
9, kubera iki muri pneumatic valve piston actuator gukoresha bizaba byinshi kandi byinshi?
Kuri pneumatic valve, pisitori ya piston irashobora gukoresha byimazeyo umuvuduko wumwuka wikirere, ubunini bwa actuator ni buto kuruta firime, igitutu ni kinini, O-impeta muri piston yizewe kuruta firime, bityo izabikora gukoreshwa byinshi kandi byinshi.
10. Kuki guhitamo ari ngombwa kuruta kubara?
Kubara no guhitamo ugereranije, guhitamo nibyingenzi cyane, biragoye cyane. Kuberako kubara ari uburyo bworoshye bwo kubara, ntibiterwa nukuri kuri formula ubwayo, ahubwo biterwa nukuri kubintu byatanzwe. Guhitamo birimo ibintu byinshi, uburangare buke, bizaganisha ku guhitamo nabi, ntibitera gusa gutakaza abakozi, umutungo wibikoresho, umutungo wimari, kandi gukoresha ingaruka ntabwo ari byiza, uzane ibibazo byinshi byo gukoresha, nko kwizerwa , ubuzima, ubwiza bwibikorwa, nibindi
Ingano yo gusaba hamwe nibisabwa bya tekiniki yumuriro wamashanyarazi (II) Ibikoresho bikoreshwa mumashanyarazi bigomba kuba bifite ibyemezo byujuje ibyangombwa cyangwa ibyemezo bijyanye: ibikoresho byicyuma bigomba gushyirwaho nimero yicyuma, nimero yumuriro numubare wicyiciro, kandi bifite imiterere yimiti nicyemezo cyumutungo wa mashini. Mugihe ibice byafunzwe byibikoresho byo kugenzura ibisubizo ni icyitegererezo cyibikorwa byubukanishi bitujuje ibyangombwa, bigomba gufata inshuro ebyiri icyitegererezo cya kabiri, niba bikiri a, iki gice cyibice bigomba kongera kuvurwa ubushyuhe, mbere ya kabiri- uburyo bwo gukora ibizamini nko kuvura ubushyuhe nanone umubare utarenze inshuro ebyiri (utabariyemo nubushyuhe), * * * ikiganiro cya kabiri niba hakiri icyitegererezo, Iki cyiciro cyibikoresho ntigishobora gukoreshwa.
