Niki gitera kunanirwa kwangirika?

Kugirango uhuze no gukoresha ibikoresho bya pneumatike byo kubungabunga, diameter ya pipe na valve-yaciwe na valve yumuyaga uhumeka muri sitasiyo rusange irashobora kwiyongera muburyo bukwiye, urugero, DN25 yongerewe ibikoresho bya DN50, hamwe nuyoboro uhuza uhuza na sitasiyo rusange irashobora gusangirwa numuyaga usohora umuyoboro wibikoresho; Kubikoresho binini, icyambu rusange gihuza (UC) gishobora gutangwa kubikoresho. Icyambu cyo guhuza hamwe na valve ya enterineti igomba kuba kumurongo wo hepfo no hejuru yibikoresho bihagaritse cyangwa kumpande zombi z'uburebure bwibikoresho bya horizontal. Iyo umuyoboro rusange wibintu ushobora kwanduzwa nuburyo bwo gutembera gutemba, kugenzura ibyingenzi bizashyirwa kumurongo wibikoresho bisanzwe byaciwe na valve.
Guhuza: Igenamiterere shingiro rya valve
Sisitemu yimikorere ya chimique muburyo bwo gushushanya imyanda yumuvuduko mwinshi hamwe na sisitemu ya parike, irashobora kwerekeza kubuyobozi bukuru
Ingingo zijyanye na Minisiteri y’inganda n’ikigo gishinzwe kubaka amashanyarazi:
Amabwiriza ya tekiniki yo gushushanya imiyoboro y'amazi yo mu mashanyarazi mu mashanyarazi (DLGJ 233-81)
Ingingo ya 7 ~ 7 1: Pg≥40 imiyoboro y'amazi n'amazi bigomba gushyirwaho mukurikirane hamwe na valve ebyiri zihagarara.
Ingingo ya 7 ~ 8 1: Pg≥40 “kubikoresho byumuyaga, imiyoboro ibiri ihagarara igomba gushyirwaho murukurikirane.
Igice cyo guhagarika umuvuduko ni kg / cm2 (imbonerahamwe).
Mugihe ukoresha, nyamuneka witondere ibiteganijwe muri *** verisiyo.
Kuri hydrocarbone, imiti yubumara kandi yangiza nibindi bikoresho nibindi bikoresho bitunganyirizwa hejuru no kuri vent, umuyoboro wa enterineti washyizeho indangagaciro ebyiri, ushobora kwifashisha Imbonerahamwe 2.0.3
Imbonerahamwe 2.0.3 ubushyuhe nubushyuhe bwimyanya ibiri
Sitasiyo rusange (sitasiyo rusange) Sitasiyo rusange (sitasiyo rusange mugufi) muruganda rwa shimi irashobora gushyirwaho ukurikije agace gafite radiyo igera kuri 15m, mugihe sitasiyo rusange hanze y’uruganda ishobora gushyirwaho Kuri Igishushanyo gikenewe. Kugabanya-valve yerekana buri cyiciro kuva DN15 kugeza DN50 biterwa nibiranga igikoresho.
Imyanda hamwe nibihuza byibikoresho rusange kuri sitasiyo birashobora kuba bidahuye nkana, kandi gahunda yibitangazamakuru muri buri sitasiyo rusange igomba kuba ihamye, kugirango hirindwe kwaguka kwimpanuka yibikoresho bitari byiza mugihe byihutirwa.
Imiyoboro y'amazi ya sitasiyo rusange yo hanze ahantu hakonje irashobora gukorwa kuburyo bukurikira:
. Niba imiyoboro ihamye hamwe na valve ikoreshwa, valve yamazi igomba kuba iri muri valve neza.
.
(3) Kubika ubushyuhe hamwe n'umuyoboro.
Kugirango uhuze no gukoresha ibikoresho bya pneumatike byo kubungabunga, diameter ya pipe na valve-yaciwe na valve yumuyaga uhumeka muri sitasiyo rusange irashobora kwiyongera muburyo bukwiye, urugero, DN25 yongerewe ibikoresho bya DN50, hamwe nuyoboro uhuza uhuza na sitasiyo rusange irashobora gusangirwa numuyaga usohora umuyoboro wibikoresho; Kubikoresho binini, icyambu rusange gihuza (UC) gishobora gutangwa kubikoresho. Icyambu cyo guhuza hamwe na valve ya enterineti igomba kuba kumurongo wo hepfo no hejuru yibikoresho bihagaritse cyangwa kumpande zombi z'uburebure bwibikoresho bya horizontal. Iyo umuyoboro rusange wibintu ushobora kwanduzwa nuburyo bwo gutembera gutemba, kugenzura ibyingenzi bizashyirwa kumurongo wibikoresho bisanzwe byaciwe na valve.
umunara
Komeza umuvuduko wamazi muri kondenseri hejuru yumunara uko bishoboka kose nkumuvuduko uri hejuru yumunara, igitonyanga cyumuvuduko wumuyoboro hejuru yumunara kugeza byibuze, usibye kuri ibikenewe bidasanzwe byo kugenzura inzira, nta valve yaciwe ishyirwa kumuyoboro kuva hejuru yumunara kugera kuri kondenseri. Umuyoboro uhuza hagati ya reboiler (harimo na reboiler yo hagati) n'umubiri wumunara ntushobora gushyirwaho na valve yaciwe, usibye ibikenewe kugirango igenzurwe cyangwa isuku mugihe ikora igikoresho.
Iyo valve yashizwe kumuyoboro uhuza amashanyarazi ya siphon yumuriro hamwe numubiri wumunara, hazakoreshwa valve yumuryango hamwe na diameter imwe numuyoboro uhuza. Isahani yimpumyi 8 igomba gushyirwaho hagati ya valve na reboiler, naho reboiler igomba gushyirwaho ibyuma byamazi, nkuko bigaragara ku gishushanyo cya 2.0.5-1. Umuyoboro umwe wa siphon yumuriro ugomba kongeramo umuyoboro uhuza ibintu byinjira muri reboiler hamwe nicyambu gisohoka munsi yumunara hanyuma ugashyiraho valve yaciwe, nkuko bigaragara ku gishushanyo cya 2.0.5-2. Diameter ya valve igomba kuba byibura 1/4 kinini kuruta umuyoboro usohoka munsi yumunara
FIG. 2.0.5-1 Siga amashyanyarazi ya siphon reboiler inzira kuruhande rwa valve
FIG. 2.0.5-2 imwe-imwe ya reboiler valve Igenamiterere
Niyihe mpamvu itera kunanirwa kwangirika?
Valve isanzwe ikoreshwa mubikoresho byo kugenzura, hariho valve irwanya anticorrosive na valve itari anticorrosive, valve mubisanzwe igenzura ingano yumuvuduko wikigereranyo cyamazi cyangwa gaze na switch, kwangirika kwa valve nimwe mumpamvu nyamukuru zitera kunanirwa na valve, hariho uburyo bwinshi bwo kwangirika cyangwa igitera ruswa, muri rusange irashobora kugabanywamo uburyo butandatu bwo kubora. Ruswa ninzira karemano kandi isesagura yo kwinjiza ibyuma mumabuye yabo.
Ubuhanga bwa chimie yibora bushimangira reaction yibanze ya ruswa ya M0M +, aho M0 ari icyuma na M nicyuma cyiza cya ionic, mugihe cyose icyuma (M0) kigumana electron, akomeza kuba icyuma. Bitabaye ibyo, bizangirika. Imbaraga zifatika Igihe kinini imbaraga zumubiri nubumashini bizakorana kugirango valve inanirwe. Hariho ubwoko bwinshi busanzwe bwa ruswa, cyane cyane. Uburyo bwo kurwanya ruswa buterwa no gukora firime irinda ruswa hejuru yicyuma. Noneho impanvu zo kunanirwa na valve kurutonde hepfo kugirango ukore intangiriro;
1, ruswa
Kwangirika kwaho cyangwa gutobora bibaho mugihe firime ikingira yangiritse cyangwa igicuruzwa cyibora cyangirika. Ibibyimba biturika kugirango bibe anode kandi ibicuruzwa bitavunitse cyangwa ibicuruzwa byangirika bikora nka cathode, bikora neza uruziga rufunze. Ibyuma bimwe bidafite ingese biroroshye gushira imbere ya ion ya chloride. Ruswa ibaho hejuru yicyuma cyangwa ibice bigoye kuko ibyo ntabwo ari kimwe.
2, kwangirika
Biturutse ku mbaraga z'umubiri zo kwambara no kurira, icyuma gishonga binyuze mu kwangirika. Ingaruka ziterwa ahanini nimbaraga n'umuvuduko. Kunyeganyega cyane cyangwa kugonda ibyuma birashobora kugira ibisubizo bisa. Cavitation nuburyo busanzwe bwa pompe yangirika, guhagarika umutima kwangirika, guhangayika cyane hamwe nikirere cyangirika bizatera kwangirika kwicyuma. Iyo guhangayikishwa cyane hejuru yicyuma birenze umusaruro wibyuma munsi yumutwaro uhagaze, ruswa yibanda kumwanya wibikorwa, kandi ibisubizo byerekana ruswa. Muguhinduranya ibyuma byangirika no gushiraho imbaraga nyinshi yibice byibice, kwangirika kurashobora kwirindwa no kugabanya imihangayiko hakiri kare, cyangwa guhitamo ibikoresho bivanze hamwe na gahunda yo gushushanya. Umunaniro wa ruswa Mubisanzwe duhuza stress ihagaze hamwe na ruswa.
3, ubushyuhe bwo hejuru
Kugirango tumenye ingaruka ziterwa n'ubushyuhe bwo hejuru, dukeneye gusuzuma aya makuru: ibigize ibyuma, imiterere yikirere, ubushyuhe nigihe cyo kwerekana. Ariko ibyuma byinshi byoroheje (byoroheje kuruta okiside) bigizwe na oxyde idakingira igenda yiyongera mugihe kandi ikagwa. Ubundi buryo bwo kwangirika kwubushyuhe bukabije burimo volcanisation, carburisation, nibindi.
4, icyuho
Ibi bibaho mu cyuho kibuza ikwirakwizwa rya ogisijeni, bigakora uduce twa ogisijeni ndende kandi ntoya kandi bigatera itandukaniro mu gukemura ibibazo. By'umwihariko, ingingo cyangwa inenge zifatanije zishobora kugaragara nkikinyuranyo gito, ubugari bwikinyuranyo (muri rusange muri 0.025 ~ 0.1mm) bihagije kugirango igisubizo cya electrolyte kibe icyuho, icyuma nicyuma hanze yicyuho kugirango habeho selile ngufi ya galvanic, hamwe na ruswa ikomeye yaho.
5, amashanyarazi
Iyo ibyuma bibiri bitandukanye bihuye kandi bigahura namazi yangirika na electrolytite, bigakora selile galvanic, ikigezweho gitera igice cya anodike kwangirika no kongera umuyaga. Ruswa mubisanzwe iba hafi aho bahurira. Kugabanya ruswa bishobora kugerwaho mugushiraho ibyuma bidasa.
6. Kwangirika hagati yimiterere
Kwangirika kwimiterere bibaho kubwimpamvu zitandukanye. Igisubizo ni kimwe no gusenya imitungo yubukorikori ku mbibi zimbuto. Kwangirika hagati yicyuma cya austenitike kitagira umuyonga kuri 800 - 1500 ° F gikorerwa ibintu byinshi byangiza (427 - 816 ° C) bitavuwe neza cyangwa bikangurira abantu. Iyi miterere irashobora gukurwaho mbere yo gufunga no kuzimya kuri 2000 ° F (1093 ° C) ukoresheje ibyuma bidafite karuboni nkeya (C-0.03 Max) cyangwa niobium cyangwa titanium.
