Tsis tas li ntawd,cov diaphragm lim xovxwmsiv tau rau cov khoom siv nyuaj uas muaj viscosity siab, muaj dej noo ntau thiab tsis ua haujlwm dewatering zoo. Qhov kev hloov kho siab yog 0.8–1.6 MPa, uas tuaj yeem hloov kho tau raws li cov khoom siv. Nws hloov kho rau ob qho tib si kev tsim khoom tsis tu ncua thiab kev ua haujlwm loj tas mus li, sib npaug zoo meej rau kev ua haujlwm zoo thiab kev siv tau zoo.
2. Cov Lus Qhia Txog Kev Xaiv Txuj Ci
Sib phim cov khoom siv raws li qhov xav tau kom ua tau zoo tshaj plaws
Kev xaiv cov tshuab lim dej diaphragm ncaj qha txiav txim siab qhov ua tau zoo ntawm kev tsim khoom, kev kho mob thiab cov nqi khiav lag luam. Kev xaiv tsis raug yuav ua rau muaj peev xwm tsis txaus ntawm cov khoom siv, cov dej noo ntawm cov ncuav mog qab zib lim tsis tsim nyog, kev siv hluav taws xob ntau lossis cov khoom siv tsis ua haujlwm. Raws li kev paub dhau los hauv kev lag luam, lub hauv paus ntsiab lus xaiv tseem ceeb yog siv cov yam ntxwv ntawm cov khoom siv ua lub hauv paus, lub peev xwm tsim khoom ua lub hauv paus, thiab cov xwm txheej ua haujlwm hauv chaw ua qhov siv. Plaub yam tseem ceeb yuav tsum tau tsom mus rau, ntxiv los ntawm kev xam lej rau kev xaiv qauv:
1. Piav qhia txog cov yam ntxwv ntawm cov khoom siv tseem ceeb
Cov yam ntxwv ntawm cov khoom siv yog qhov tseem ceeb rau kev xaiv. Cov yam ntxwv tseem ceeb uas yuav tsum paub meej suav nrog kev sib xyaw ua ke, viscosity, qhov loj ntawm cov khoom me me, kev xeb thiab qhov kub ntawm cov tshuaj.
Rau cov ntaub ntawv xeb, xaiv cov diaphragms ua los ntawm fluororubber, polypropylene thiab lwm yam ntaub ntawv tiv thaiv xeb; rau cov ntaub ntawv kub siab, siv cov diaphragms tiv taus kub siab nrog qhov kub ua haujlwm hauv 120 ℃. Rau cov ntaub ntawv viscosity siab thiab cov khoom me me, xaiv cov qauv nrog thaj chaw lim dej loj thiab lub zog nias siab kom lav qhov cuam tshuam ntawm kev tshem dej.
Lub caij no, paub meej tias cov dej noo pib li cas (feem ntau yog 97.5%–99.2%) thiab cov dej noo uas xav tau (feem ntau yog 60%–65%) los muab lub hauv paus rau kev xam thaj chaw lim dej.
2. Sib phim qhov peev xwm tsim khoom tiag tiag
Xam qhov chaw lim dej uas xav tau raws li qhov ntim khoom ua txhua hnub, kev ua haujlwm hloov pauv thiab lub voj voog lim dej, uas yog qhov tseem ceeb rau kev xaiv qauv.
Cov txheej txheem suav suav nrog txoj kev ntim cov av ntub thiab txoj kev ntim cov av qhuav. Txoj kev ntim cov av ntub yog qhov pom zoo rau kev nrhiav cov ntaub ntawv yooj yim.
Cov qauv tseem ceeb:
S = 1000 × V1 × (1-a) ÷ (1-b) ÷ 15 ÷ t
S = Thaj chaw lim dej; V1 = Qhov ntim ntawm cov khoom ua ntej lim dej; a = Cov dej noo pib thaum pib; b = Cov dej noo uas xav tau; t = Lub voj voog ua haujlwm txhua hnub
Piv txwv li: Cov dej ntws tawm txhua hnub los ntawm kev kho dej phwj hauv tsev yog 360m³, cov dej noo pib 98%, cov dej noo lub hom phiaj 65%, 3 lub voj voog ua haujlwm ib hnub. Thaj chaw lim dej xam yog li 853㎡. Hauv kev xaiv tiag tiag, xaiv tus qauv loj dua li tus nqi theoretical me ntsis kom ua tau raws li qhov xav tau ua tiav.
3. Hloov Kho Kom Haum Rau Cov Xwm Txheej Ua Haujlwm Hauv Chaw
Xaiv cov qauv khoom siv thiab txoj kev teeb tsa kom haum raws li qhov chaw teeb tsa hauv tsev, kev muab hluav taws xob, cua thiab dej.
Yog tias qhov chaw tsawg, xaiv cov tshuab lim dej me me lossis cov tshuab diaphragm uas tau teeb tsa rau ntawm daim phiaj; rau cov chaw uas tsis muaj cua txaus, xaiv cov qauv uas siv hydraulically squeezing; rau kev tsim khoom tas mus li, siv cov qauv tsis siv neeg uas muaj PLC tswj system kom ua haujlwm tau yam tsis muaj neeg saib xyuas. Cov lag luam me thiab nruab nrab tuaj yeem xaiv cov chav tsev uas muaj thaj chaw lim dej ntawm 4–300㎡ kom sib npaug tus nqi thiab peev xwm.
4. Muab Qhov Tseem Ceeb Rau Kev Txuag Hluav Taws Xob Thiab Kev Ua Haujlwm & Kev Kho Tom Qab
Ua tib zoo saib xyuas kev siv hluav taws xob thiab tus nqi txij nkawm thaum xaiv. Muab qhov tseem ceeb rau cov qauv txuag hluav taws xob nrog cov lim dej zoo tshaj plaws thiab kev tsim cov kav dej ntws, uas tuaj yeem txo kev siv hluav taws xob los ntawm 30% piv rau cov khoom siv ib txwm muaj.
Lub caij no, xaiv cov qauv uas muaj cov ntaub lim tsawg, yooj yim hloov thiab qis qhov ua tsis tiav kom ntev lub neej kev pabcuam thiab txo cov nqi kho tom qab. Cov khoom siv xaiv tau xws li lub tshuab ntxuav ntaub lim tsis siv neeg thiab lub tshuab ziab khaub ncaws tuaj yeem teeb tsa raws li qhov xav tau los txhim kho kev siv cov khoom siv.
