Amakuru - Ni ibihe bibazo bishobora guterwa no guhagarika valve isohoka mugihe cya pompe ya centrifugal?

Kugumisha hanze ya valve ifunze mugiheAmapompe ya Centrifugalimikorere itangiza ibyago byinshi bya tekiniki.

Guhindura ingufu zitagenzuwe hamwe nubusumbane bwa termodinamike

1.1 Mugihe cyafunzwe cyubushyuhe bwo hagati, hafi yingufu zose zinjira zihinduka ingufu zubushyuhe. Ikigereranyo ntigishobora gukuramo ubushyuhe, bigatuma ubushyuhe mucyumba cya pompe buzamuka cyane. Gukomeza gukora bizatera umwuka mubi, byihutisha karubone yibikoresho bifunze

1.2 Kunanirwa kwa kashe Mubidukikije byubushyuhe bwo hejuru no guhumeka hagati, kashe ya mashini ishingiye kumavuta no gukonjesha ikigereranyo bizananirana ubushyuhe bukabije - kashe ya mashini izaba ifite ubwumvikane buke kandi mumaso ya kashe izatwikwa.

Guhangayikishwa bidasanzwe

2.1 Imbaraga za Axial zirengereye Imbaraga za axial zifunga valve mubisanzwe zikubye inshuro 1.5-5 zumurimo usanzwe wakazi, kandi umutwaro wo gutwara ibintu ushobora kugera cyangwa ukarenga imipaka yabyo, bikavamo gucikamo akazu kegeranye cyangwa guhindura akazu.

Cavitation no kwangiza ibintu

3.1 Amafaranga ya NPSH yahinduye imyuka iciriritse [kora amafaranga ya cavitation (NPSHa) yigikoresho kiri munsi ya NPSHr ikenewe ya pompe], ikora ibibyimba, hamwe numuvurungano watewe no gusenyuka kwinshi bishobora kugera kuri 690MPa, bikaviramo gutobora nubuki bukwirakwira abiruka.

3.2 Kwangirika kwimiterere ya Metallografiya Kubitera ibyuma bya austenitike bitagira umuyonga, ubukangurambaga bushobora kubaho mubushyuhe bwo hejuru bwaho, kandi igipimo cyo kwangirika hagati yisi kiziyongera kandi imbaraga za tensile zizagabanuka. Ku byuma byangiza ibyuma bya karubone, ibibazo byubushyuhe bwo hejuru birahambaye cyane, nka okiside yubushyuhe bwo hejuru hamwe na decarburisation, bigatuma imbaraga zubutaka zigabanuka na politiki rusange; Niba irimo umwanda nka sulfure na fosifore, biroroshye gutandukanya imbibi z’ingano ku bushyuhe bwinshi, bigatera ubukana bw’ubushyuhe no guturika byoroshye mu gihe cyo gukora; Mugihe cy'ubushyuhe burebure bwigihe kirekire, ibyuma bya karubone bifite imbaraga zo guhangana n’ibikurura, kandi ubushyuhe bwo hejuru bwaho bushobora kwihutisha ihinduka ryimiterere, amaherezo bikazana kuvunika kwimuka cyangwa kunanirwa umunaniro.

Umutekano wa sisitemu n'ingaruka zubukungu

Kwangirika kwimikorere idasanzwe yibitangazamakuru

Kubitangazamakuru bihindagurika (urugero, LPG), imikorere ya valve ifunze bizihutisha guhumeka kwicyiciro cyamazi, kandi gazi-isukari yibice bibiri byicyumba cya pompe bizatera impinduka zitunguranye, bikaviramo guhindagurika kwigihe cyingufu za axial no kwihutisha kwambara kw ibice.

Uburambe bwinganda nibisabwa bisanzwe

6 Birasabwa gushiraho sisitemu yo kugenzura kugirango ihite itangiza gahunda yo gukingira porogaramu iyo valve isohoka ifunze kandi ikarenza.

6.2 Ibisobanuro bisanzwe bisaba ko API 610 Edition Edition ya 12 ivuga ko ingufu zimwe na zimwe, pompe zikoreshwa cyane cyangwa pompe nyinshi zifite ubushyuhe bwihuse iyo valve isohoka ifunze, bigatuma igeragezwa ridashoboka kandi / cyangwa umutekano muke mugihe valve ifunze. Kwiyongera k'ubushyuhe bifitanye isano rya bugufi n'ubucucike bw'imbaraga. Ubucucike bwimbaraga PD, ishobora kugereranywa nka:

P amanota: Urwego rwimbaraga kuri buri cyiciro iyo amazi muri hp (cyangwa MW)

D imp: Ikigereranyo cya diameter yimodoka muri. (Cyangwa m)

D nozzle: Nominal outlet flange diameter muri. (Cyangwa m). Kubiri-guswera, pompe imwe imwe, D nozzle ni inlet ya flange diameter.

Agaciro gasanzwe kuri PD ni 0.286 hp / muri.3 (13 MW / m3), hejuru yacyo birasabwa kudakoresha pompe hamwe na valve isohoka ifunze mugihe cyo kugerageza imikorere.
