Vim li cas npauj npaim valve mus cavitation?

Qhov kev ua tau zoo ntawmNpauj Npaim Li QubTxhawm rau cavitation yog ze rau lawv cov qauv kev ua yeeb yam, cov yam ntxwv kua hluav taws xob, thiab kev ua haujlwm. Cov laj thawj tshwj xeeb yog raws li hauv qab no:

1. Tus npauj npaim valve ua rau kev tsim cov chaw muaj txiaj ntsig hauv zos

Qhov qhib thiab kaw cov Cheebtsam ntawm Npauj npaim li qub yog disc-puab cov phaj npauj npaim. Thaum tig qhib, cov kua xav tau ntws ib ncig ntawm ntug ntawm npauj npaim npauj npaim. Ib cheeb tsam qis qis-siab yuav sau qab npauj npaim npauj npaim (hauv qab nqes). Thaum cov kua dej ntws qis dua hauv qab lub vapor noo, yaj roj hauv cov kua yuav precipitate thiab sau npuas, uas yog thawj theem ntawm cavitation.

Cov xwm txheej raug: Nyob rau hauv kev kub siab txawv lossis qib ceev dej ntws paug, khiav tawm ntawm ntug ntawm npauj npaim npauj npaim. Raws li Bernoulli lub hauv paus ntsiab lus, qhov nce zuj zus hauv kev txo qis, ntxiv tau cov chaw muaj txiaj ntsig zoo thiab tsim cov mob rau cavitation.

2. Kev cuam tshuam ntawm kev muaj dej hauv kev kub ntxhov thiab npuas

Thaum cov kua dej nqa cov npuas rau hauv qhov chaw siab (xws li cov kav dej hauv qab ntawmNpauj Npaim Li Qub), npuas yuav vau, tsim cov dav hlau micro uas cuam tshuam rau cov hlau nto. Qhov ntau zaus ntawm qhov kev cuam tshuam no yog qhov siab heev (nce txog ntau txhiab lub sij hawm ib ob), ua rau muaj kev sib tw zuj zus thiab tev thaum kawg ua rau cov khoom sib khi.

Cov ntaub ntawv txhawb nqa: Qhov kev sim tau pom tias qhov cuam tshuam ntawm npuas ua haujlwm tuaj yeem ncav cuag ntau pua lub zog ua lub zog ntawm cov khoom siv hlau zoo tib yam ntawm cavitation kev puas tsuaj.

3. Tus cwj pwm tswj hwm ntawm npauj npaim li qub exacerbate qhov kev pheej hmoo ntawm cavitation

Npauj npaim li qub yog siv rau kev tswj hwm ntws, tab sis thaum qhib kev sib tw me me, ua rau muaj kev sib tw ntawm npauj npaim

Cov ntaub ntawv hluav taws xob: nyob rau hauv lub inlet valve lossis dej phwj tuaj yeem tshwm sim tom qab lub chaw nres tsheb me me, yog tias yuav hloov lub zog me me, yog qhov hloov chaw ntawm lub valve lossis cov nplhaib sib dhos.

4. Tus yam ntxwv ntawm cov yam ntxwv nruab nrab thiab kev ua haujlwm

Particle muaj nruab nrab: Yog tias cov kua dej muaj cov tawv tawv xws li cov pob thiab hlau oxides, tsim ib qho "erosion cavitation" puas tsim kev puas tsuaj thiab nrawm qhov tsis ua haujlwm thiab ua kom nrawm dua.

Kev kub siab los yog corrosive tshaj tawm: kub tuaj yeem txo cov nro ntawm cov kua thiab txhawb kev tsim cov npuas; Corrosive Media tuaj yeem ua kom tsis muaj zog ntawm cov khoom muaj peev xwm ntawm cov ntaub ntawv hlau, thiab cov txiaj ntsig dual

5. Kev txwv ntawm npauj npaim Valve thiab cov qauv

Ib Leeg Eccentric / Call Npauj Npauj Npaim Valve: Nws yog ib qho tsim nyog los xav txog cov kev taw qhia ntawm dej ntws (valve phaj biasedhuab). Rov qab installation yuav ua rau muaj kev ruaj khov ntawm qhov chaw txaus thiab nce txoj kev pheej hmoo ntawm cavitation.

Ntsug qhov hluav taws xob tso hluav taws xob: tus kheej qhov hnyav ntawm lub pob valve tej zaum yuav ua rau muaj kev ntxhov siab tsis sib xws ntawm cov chaw sib khi thiab ua rau lub cav.

Mos muag npauj npaim valve: Roj hmab sealing rings yog nquag mus rau tev thiab kev puas tsuaj hauv lub cavitation cuam tshuam, thaum lub sij hawm sib zog sib luagNpauj Npaim Li Qub, txawm hais tias resistant rau yaig, muaj cov nqi siab dua thiab cov ntawv thov txwv.
