Haba hari itandukaniro hagati ya WC6 na WC9 ibikoresho bya valve, itandukaniro ririhe?

Ikintu cyingenzi cyibikoresho bya valve ni coefficient de coiffe na cavitation coeffisente ya valve, isanzwe iboneka mumibare yimibiri ikorerwa mubihugu byateye imbere mu nganda, ndetse ikanacapwa muri sample. Igihugu cyacu gitanga valve mubusanzwe ntigifite aya makuru, kuko kubona iyi ngingo yamakuru agomba gukora igerageza kugirango tubashe gushyira imbere, iki nicyo gihugu cyacu ndetse nisi yateye imbere kurwego rwicyuho cya valve kimwe mubikorwa byingenzi .
A, coefficient ya valve
Coefficient ya valve nigipimo cyibipimo byerekana ubushobozi bwa valve, nini nini ya coefficient de la flux, amazi atembera muri valve mugihe igihombo cyumuvuduko ari gito.
Ukurikije KV agaciro kubara
Aho: KV - coefficient ya Q - umuvuduko wamazi m3 / h δ P - umuvuduko wumuvuduko wa barP - ubwinshi bwamazi kg / m3
Babiri, coefficient ya valve cavitation
Cavitation coefficient δ agaciro gakoreshwa mukumenya ubwoko bwubwubatsi bwa valve bwo guhitamo kugenzura imigendekere.
Aho: H1 - umuvuduko mH2 - itandukaniro riri hagati yumuvuduko wikirere hamwe numuvuduko wumwuka wumuyaga uhuye nubushyuhe M δ P - itandukaniro riri hagati yumuvuduko mbere na nyuma ya valve M
Coefficient yemewe ya cavitation iratandukana mumibande bitewe nuburyo butandukanye. Nkuko bigaragara ku gishushanyo. Niba coefficient ya cavitation yabazwe iruta iyemerwa rya cavitation yemewe, imvugo iremewe kandi cavitation ntizabaho. Niba coefficente yemewe ya cavitation ari 2.5, hanyuma:
Niba δ> 2.5, cavitation ntizabaho.
Iyo 2.5> δ> 1.5, habaho cavitation nkeya.
Iyo δ Gukomeza gukoresha δ Shingiro kandi ikora iranga imirongo ya valve ntabwo yerekana igihe cavitation ibaye, kereka aho ingingo igeze igeze. Binyuze mu kubara hejuru birasobanutse. Kubwibyo rero, cavitation ikorwa kubera ko amazi yihuta anyuze mugice cyo kugabanuka mugice cyo gutembera, igice cyamazi kiva mumazi, kandi ibibyimba byabyaye noneho bigaturika mugice gifunguye nyuma ya valve, ifite ibintu bitatu:
(1) Urusaku
(2) kunyeganyega (kwangirika gukomeye kwishingiro ninzego zijyanye nabyo, bikaviramo gucika intege)
(3) Kwangiza ibikoresho (isuri yumubiri wa valve numuyoboro)
Duhereye ku mibare yavuzwe haruguru, ntabwo bigoye kubona ko cavitation ifitanye isano cyane nigitutu H1 nyuma ya valve. Kongera H1 biragaragara ko bizahindura ibintu no kunoza uburyo:
A. Shyira valve hasi kumurongo.
B. Shyira isahani ya orifice mu muyoboro uri inyuma ya valve kugirango wongere imbaraga.
C. Isoko ya valve irakinguye kandi yegeranya mu buryo butaziguye ikigega, cyongera umwanya wo guturika kwinshi kandi kigabanya isuri.
Isesengura ryuzuye ryibintu bine byavuzwe haruguru, muri make incamake yumuryango, ikinyugunyugu kinyugunyugu nyamukuru nibiranga urutonde kugirango byoroshye guhitamo. Ibice bibiri byingenzi bigira uruhare runini mubikorwa bya valve.
Haba hari itandukaniro hagati yibikoresho bya valve WC6 na WC9? Ni irihe tandukaniro? Ibikoresho bya Valve WC6 na WC9: BYINSHI WC6 na WC9 nibyuma bivanze, bifite ahanini imiterere yubukanishi, hamwe nimbaraga zingana, imbaraga zitanga umusaruro no kuramba mubushyuhe bwicyumba.
Kwemeza ibikoresho WC6 na WC9
WC6 na WC9 byombi ni ibyuma bivangavanze bifite ahanini imashini imwe nimbaraga zimwe, imbaraga zitanga imbaraga no kuramba mubushyuhe bwicyumba.
Itandukaniro ni ibivanze. Ugereranije na WC6, WC9 irimo chromium na molybdenum nyinshi, bityo imbaraga zayo zikoreshwa mubushyuhe bwinshi nibyiza. Byongeye kandi, WC9 ifite ubushobozi bwiza bwo kurwanya gushakisha.
