Kev paub yooj yim ntawm cov twj siv tshuaj

Yuav ua li cas xaiv lub twj tso kua mis haum tshaj plaws yeej ib txwm muaj kev txhawj xeeb rau tib neeg. Nws yeej tsis yooj yim rau koj xaiv txoj caitshuaj twj tso kua misvim tag nrho cov xwm txheej no tseem ceeb: lub sijhawm, xov xwm, khoom siv, thiab lwm yam.

Peb muaj ntawm no cov ncauj lus kom ntxaws tshaj plaws ntawm ntau hom twj tso kua mis, thiaj li yuav muab koj lub tswv yim meej ntawm hom tshuaj twg koj yuav tsum xaiv.

Txhawm rau xaiv lub twj tso kua mis, peb yuav tsum xub nkag siab thiab paub cov ntsiab lus ntawm kev xaiv tshuaj twj tso kua mis. 

1. Cov twj tso kua mis xaiv thiab kev ua tau zoo nyob rau hauv txoj kab nrog lub cuab yeejntws, taub hau, siab, kub, cavitation ntws, suction thiab lwm yam txheej txheem tsis.

2. Yuav tsum qhia meej txog qhov yuav tsum tau muaj ntawm cov yam ntxwv nruab nrab.

Nyob rau hauv kev thauj cov nplaim taws, tawg toxicity los yog kim xov xwm twj tso kua mis, yuav tsum tau ib tug txhim khu kev qha foob los yog siv cov pa xau-dawb twj, xws limagnetic drive twj tso kua mis,diaphragm twj tso kua mis,thaiv lub twj tso kua mis.

3. Cov kis tau tus mob corrosive media twj tso kua mis, mechanical kev ntseeg tau, tsis tshua muaj suab nrov, kev co.

4. Kev lag luam yuav tsum coj mus rau hauv tus account tus nqi ntawm cov cuab yeej siv, cov nqi khiav lag luam, kev tu thiab kev tswj xyuas tus nqi qis tshaj plaws.

5. Lub sijhawm nquag, tshuaj lom neeg lub twj tso kua mis xaiv:

(1) centrifugal twj tso kua misnrog kev kub ceev, me me, lub teeb yuag, kev ua haujlwm siab, loj txaus, qauv yooj yim, tsis muaj pulsation ntawm infusion, kev ua haujlwm ruaj khov, kev ua haujlwm yooj yim thiab kev saib xyuas yooj yim thiab lwm yam.

(2) Muaj qhov yuav tsum tau ntsuas, kev xaiv ntawm metering twj tso kua mis.

(3) Lub taub hau yuav tsum muaj siab heev, qhov ntws me me thiab tsis muaj qhov tsim nyog me me ntws high-lift centrifugal lub cev muaj zog twj tso kua mis tuaj yeem siv tau, lub twj tso kua mis xaiv tau, xws li cavitation yuav tsum tsis siab kuj tuaj yeem siv lub twj tso kua mis vortex.

(4) Lub taub hau qis heev, ntws loj, kev xaiv ntawm axial flow twj tso kua mis thiab cov twj tso kua mis sib xyaw.

(5) Nruab nrab viscosity (ntau dua 650 ~ 1000mm2 / s), xav txog kev xaiv rotor twj tso kua mis los yog reciprocating twj tso kua mis (iav twj tso kua mis, ntsia hlau twj tso kua mis)

(6) Cov ntsiab lus roj nruab nrab ntawm 75%, tus nqi ntws me me thiab cov viscosity tsawg dua 37.4mm2 / s, qhov kev xaiv ntawm vortex twj tso kua mis.

Qhov pib ntawm nquag lossisirrigation twjinconvenience zaus, yuav tsum siv tus kheej-priming kev ua tau zoo ntawm lub twj tso kua mis, xws liself-priming centrifugal twj tso kua mis,self-priming vortex twj tso kua mis, pneumatic (hluav taws xob) siab twj tso kua mis.

Nrhiav convection qhov chaw siv cov khoom siv corrosion-resistant cov twj tso kua mis xaiv raws li tus txheej txheem yuav tsum tau ua raws li cov dej thiab cov dej xav tau, los ntawm tsib yam yuav tsum tau txiav txim siab. 

1. Flow yog ib qho ntawm cov ntaub ntawv tseem ceeb ntawm kev ua haujlwm ntawm lub twj tso kua mis, nws yog ncaj qha ntsig txog cov peev txheej tsim thiab kev sib kis ntawm tag nrho cov cuab yeej. Xws li lub koom haum tsim cov txheej txheem tsim tuaj yeem xam lub twj tso kua mis ib txwm, yam tsawg kawg nkaus, ntau tshaj peb hom kev khiav tsheb. Xaiv lub twj tso kua mis, qhov siab tshaj plaws ntws raws li lub hauv paus, coj mus rau hauv tus account qhov qub ntws, thaum tsis muaj qhov siab tshaj plaws ntws, nws yog qhov xav tau 1.1 npaug ntawm qhov dej ib txwm ua raws li qhov siab tshaj plaws ntws.

2. Lub tshuab ntaus ntawv yuav tsum tau nqa lub twj tso kua mis yog lwm cov ntaub ntawv tseem ceeb ntawm kev ua haujlwm, kev siv dav dav ntawm amplification 5% -10% margin rau lub taub hau tom qab xaiv.

3. Cov khoom ua kua, suav nrog cov kua nruab nrab lub npe, cov khoom siv lub cev, cov khoom siv tshuaj lom neeg thiab lwm yam khoom, uas muaj feem xyuam rau lub taub hau ntawm lub cev, kev ua haujlwm zoo NPS suav thiab hom twj tso kua mis tsim nyog, cov khoom siv twj tso kua mis xaiv thiab siv hom kev foob hom.

4. Cov txheej txheem ntawm cov kav dej ntawm qhov kev teeb tsa yog hais txog qhov siab ntawm cov kua dej, qhov kev ncua deb ntawm cov kua xa tawm, qhov tsawg kawg ntawm cov kua theem ntawm qhov nqus, qhov siab tshaj plaws ntawm cov kua dej tawm sab, thiab lwm yam. , lengths, cov ntaub ntawv, Thiab thiaj li nyob rau, thiaj li yuav nqa nyob rau hauv lub comb lub taub hau xam thiab NPSH kos.

5. Kev txiav txim siab ntawm kev ua haujlwm, xws li kev khiav hauj lwm ua kua T saturated vapor siab, suction sab siab (tswj), tawm sab hlab ntsha siab, qhov siab, ambient kub khiav yog qhov sib txawv los yog tas mus li, seb lub twj tso kua mis txoj hauj lwm yog tsau los yog txav ntawm. Yog lub hauv paus tseem ceeb rau kev xaiv. Cov ntaub ntawv xws li AFB stainless hlau corrosion-resistant twj tso kua mis, CQF engineering yas magnetic tsav twj tso kua mis.

Rau kev sib kis ntawm cov khoom uas muaj cov xov xwm, kev siv cov khoom siv convective xav tau cov ntaub ntawv hnav-tiv taus, yog tias tsim nyog, lub foob foob nrog cov kua dej huv.

Pipeline kev npaj cov twj siv tshuaj

Nyob rau hauv lub tsim layout pipeline, yuav tsum nco ntsoov cov hauv qab no:

A. Tsim nyog xaiv ntawm cov yeeb nkab txoj kab uas hla, cov yeeb nkab txoj kab uas hla, nyob rau tib lub ndlwg tus nqi, qhov khiav ceev yog me me, qhov kev tiv thaiv poob yog me me, tab sis tus nqi siab, cov yeeb nkab txoj kab uas hla yog me me, yuav ua rau ib tug ntse nce nyob rau hauv tsis kam poob. , lub taub hau twj tso kua mis nce Nrog kev nce hauv lub zog, cov nqi thiab cov nqi khiav lag luam tau nce. Yog li ntawd yuav tsum tau txiav txim siab los ntawm kev siv tshuab thiab kev lag luam.

B. Exhaust yeeb nkab thiab nws cov fittings yuav tsum muaj peev xwm nyob rau hauv lub siab lub siab tshaj plaws.

C. cov yeeb nkab layout yuav tsum tau teem kom ncaj raws li qhov ua tau kom txo tau cov yeeb nkab fittings thiab txo qhov ntev ntawm cov yeeb nkab yuav tsum tau tig thaum lub vojvoog dabtsi yog khoov ntawm lub luj tshib yeeb nkab txoj kab uas hla yuav tsum yog 3 mus rau 5 npaug ntawm lub kaum sab xis kom ntau li ntau tau. 90lt; ib. 0 & gt;ua. C.

D. Lub tso tawm sab ntawm lub twj tso kua mis yuav tsum tau nruab nrog li qub (pob lossis lub ntiaj teb valve, thiab lwm yam) thiab kos valve. Lub valve yog siv los kho qhov chaw ua haujlwm ntawm lub twj tso kua mis. Lub check valve tiv thaiv lub twj tso kua mis los ntawm kev thim rov qab thaum cov kua rov qab thiab tiv thaiv lub twj tso kua mis los ntawm kev ntaus cov dej rauj. (Thaum cov kua dej rov qab, nws yuav muaj qhov rov qab siab loj, lub twj tso kua mis puas).
