Dukurikije iperereza nisesengura, ruswa ni kimwe mu bintu byingenzi byangiza imyanda yikinyugunyugu. Kuberako umwobo w'imbere uhura nuburyo, bwangiritse cyane. Nyuma yo kwangirika, diameter ya valve iba ntoya kandi irwanya umuvuduko wiyongera, bigira ingaruka kumyuka yikigereranyo. Ubuso bwumubiri wa valve bushyirwa ahanini kubutaka cyangwa munsi yubutaka. Ubuso burahuye numwuka kandi umwuka uba mwinshi, kuburyo bikunda kubora. Intebe ya valve itwikiriwe rwose aho cavit y'imbere ihuye nikigereranyo. Kubwibyo, kuvura hejuru yumubiri wa valve na plaque ya plaque nuburyo bwiza cyane bwo kurinda uburyo bwo kwirinda kwangirika kw ibidukikije hanze.
1. Uruhare rwibinyugunyugu byo hejuru
01. Kumenyekanisha ibikoresho byumubiri
Ibara ryubuso bwibara ryashyizwe kumurongo utagizwe numubiri wa valve na bonnet. Binyuze muri iri bara ryerekana, dushobora kumenya byihuse ibikoresho byumubiri wa valve kandi tukumva neza ibiranga.
| Valve Ibikoresho byumubiri | Ibara | Valve Ibikoresho byumubiri | Ibara |
| Shira Icyuma | Umukara | Icyuma | Ubururu |
| Icyuma gihimbano | Umukara | WCB | Icyatsi |
22. Ingaruka zo gukingira
Nyuma yumubiri wa valve usize irangi, ubuso bwumubiri wa valve butandukanijwe nibidukikije. Ingaruka zo gukingira zishobora kwitwa ingaruka zo gukingira. Ariko, hagomba kwerekanwa ko ibara ryoroshye ridashobora gutanga ingaruka zo gukingira byimazeyo. Kubera ko polymers ifite urwego runaka rwo guhumeka, iyo igifuniko ari gito cyane, imyenge yubatswe ituma amazi na molekile ya ogisijeni bigenda byisanzuye. Ibyuma bifunga byoroheje bifite ibyangombwa bisabwa kubyimbye bya epoxy resin itwikiriye hejuru. Kugirango tunoze ubudahangarwa bwikibiriti, impuzu zirwanya ruswa zigomba gukoresha ibintu bikora firime bifite umwuka muke muke hamwe nuwuzuza ibintu bifite imbaraga zo gukingira. Muri icyo gihe, umubare w’ibipfundikizo ugomba kwiyongera kugirango igipfundikizo kigere ku mubyimba runaka kandi ni cyinshi kandi kidahwitse.
03. Kubuza ruswa
Ibice by'imbere by'irangi bifata hamwe nicyuma kugirango inyuze hejuru yicyuma cyangwa ikore ibintu birinda kugirango irinde ingaruka zo gukingira. Kuri valve ifite ibisabwa byihariye, ugomba kwitondera irangi kugirango wirinde ingaruka mbi. Byongeye kandi, ibyuma bifata ibyuma bikoreshwa mu miyoboro ya peteroli birashobora kandi gukora nkibikoresho byangiza ruswa bitewe nibicuruzwa byangirika biterwa nigikorwa cyamavuta amwe nigikorwa cyo kumisha amasabune yicyuma.
44. Kurinda amashanyarazi
Iyo dielectric yinjira muri coating ihuye nubuso bwicyuma, kwangirika kwamashanyarazi munsi ya firime. Ibyuma bifite ibikorwa byinshi kuruta ibyuma bikoreshwa nkuzuza ibifuniko, nka zinc. Bizagira uruhare mu kurinda nka anode yo gutamba, kandi ibicuruzwa byangirika bya zinc ni umunyu wa zinc chloride ushingiye ku munyu na karubone ya zinc, bizuzuza icyuho kiri muri firime kandi bituma firime ikomera, bigabanye cyane ruswa kandi byongere ubuzima bwa serivisi ya indangantego.
2. Impuzu zikunze gukoreshwa kumatara yicyuma
Uburyo bwo kuvura hejuru yububiko burimo ahanini gusiga irangi, galvanizing hamwe nifu ya poro. Igihe cyo kurinda irangi ni kigufi kandi ntigishobora gukoreshwa mugihe cyakazi igihe kirekire. Inzira ya galvanizing ikoreshwa cyane cyane mumiyoboro. Byombi bishyushye-bigabanya amashanyarazi hamwe na electro-galvanizing ikoreshwa. Inzira iragoye. Kwiyitirira gukoresha uburyo bwo gutoragura na fosifati. Hazaba hasigaye aside na alkali hejuru yumurimo wakazi, hasigara ruswa Akaga kihishe gatuma igorofa ryoroshye kugwa. Kurwanya ruswa yibyuma ni imyaka 3 kugeza 5. Ifu yifu ikoreshwa mubibaya byacu bya Zhongfa ifite ibiranga igipfundikizo cyinshi, kurwanya ruswa, kurwanya isuri, nibindi, bishobora kuzuza ibisabwa na valve mugihe ikoreshwa rya sisitemu yamazi.
01. Valve umubiri epoxy resin coating
Ifite ibi bikurikira:
· Kurwanya ruswa: Epoxy resin isize ibyuma bifite ibyuma birwanya ruswa, kandi imbaraga zo guhuza na beto ziragabanuka cyane. Birakwiriye mubihe byinganda mubidukikije cyangwa ibitangazamakuru byangirika.
· Kwizirika gukomeye: Kubaho kwamatsinda ya hydroxyl ya polar hamwe na ether ihuza imiterere ya epoxy resin molekulari ituma ifata cyane mubintu bitandukanye. Kugabanuka kwa epoxy resin iyo ikize iba mike, imihangayiko yimbere yatanzwe ni nto, kandi gutwikira hejuru kurinda ntibyoroshye kugwa no gutsindwa.
· Ibikoresho by'amashanyarazi: Sisitemu yakize ya epoxy resin ni ibikoresho byiza cyane byokwirinda bifite imiterere ya dielectric, irwanya kumeneka hejuru, hamwe no kurwanya arc.
· Mold Resistant: Sisitemu yakize ya epoxy resin irwanya ibishushanyo byinshi kandi irashobora gukoreshwa mubihe bishyuha.
02. Valve isahani nylon isahani
Amabati ya Nylon arwanya ruswa cyane kandi yakoreshejwe neza mubikorwa byinshi nk'amazi, ibyondo, ibiryo ndetse no guta amazi yo mu nyanja.
· Imikorere yo hanze: Isahani ya nylon irashobora gutsinda ikizamini cyo gutera umunyu. Ntabwo yigeze ikuramo nyuma yo kwibizwa mu mazi yo mu nyanja imyaka irenga 25, bityo rero ntihabeho kwangirika kwicyuma.
· Kwambara birwanya: Kurwanya kwambara neza.
· Kurwanya ingaruka: Nta kimenyetso cyo gukuramo ingaruka zikomeye.
3. Uburyo bwo gutera
Igikorwa cyo gutera ni ugukora ibihangano → gukuramo ivumbi → kubishyushya → gutera (primer - trimming - topcoat) → gukomera → gukonja.
Gutera Gusasa cyane cyane gutera amashanyarazi. Ukurikije ubunini bwakazi, gutera imiti ya electrostatike birashobora kugabanywamo ifu ya electrostatike yumurongo wumurongo wumurongo hamwe nifu ya poro ya electrostatike. Inzira zombi ni zimwe, kandi itandukaniro nyamukuru nuburyo bwo guhinduranya akazi. Umurongo utanga spray ukoresha urunigi rwohereza mu buryo bwikora, mugihe igice cya spray cyazamuwe nintoki. Ubunini bwikibiriti bugenzurwa kuri 250-300. Niba umubyimba uri munsi ya 150 mm, imikorere yo kurinda izagabanuka. Niba umubyimba urenze 500 mkm, gufatira hamwe bizagabanuka, kurwanya ingaruka bizagabanuka, kandi ifu yiyongera.
