Pump xaiv txoj cai
1. Ua kom hom thiab kev ua haujlwm ntawm lub twj tso kua mis xaiv tau raws li qhov yuav tsum tau ua ntawm cov txheej txheem tsis xws li cov cuab yeej ntws, lub taub hau, siab, kub, cavitation ntws, thiab nqus.
2. Yuav tsum ua kom tau raws li qhov xav tau ntawm cov yam ntxwv nruab nrab.
Rau cov twj siv hluav taws xob xa hluav taws xob, tawg, tshuaj lom lossis muaj txiaj ntsig tshaj tawm, yuav tsum muaj cov ntsaws ruaj ruaj ruaj ruaj lossis cov twj tsis muaj dej, xws li cov twj sib nqus tsav, cov twj diaphragm, thiab cov twj tso kua mis; rau cov twj conveying corrosive media, corrosion-resistant qhov yuav tsum tau rau convection qhov chaw. Cov ntaub ntawv, xws li AFB stainless hlau corrosion-resistant twj, CQF engineering plastics magnetic drive twj.
Rau cov twj tso kua mis uas muaj cov khoom siv, cov khoom siv convection yuav tsum tau ua los ntawm cov ntaub ntawv hnav-resistant, thiab lub foob foob yuav tsum tau yaug nrog cov kua dej huv yog tias tsim nyog.
3. Cov neeg kho tshuab kev ntseeg siab, tsis tshua muaj suab nrov thiab kev co me me.
4. Kev lag luam, tag nrho cov nqi ntawm cov cuab yeej siv, cov nqi khiav lag luam, cov nqi tu thiab cov nqi tswj yuav tsum raug suav tias yog qhov qis tshaj.
5. Lub twj tso kua mis centrifugal muaj cov yam ntxwv ntawm kev kub ceev, me me, lub teeb yuag, kev ua haujlwm siab, tus nqi ntws loj, cov qauv yooj yim, tsis muaj pulsation hauv infusion, kev ua haujlwm ruaj khov, kev ua haujlwm yooj yim thiab kev saib xyuas yooj yim.
Yog li ntawd, tshwj tsis yog rau cov xwm txheej hauv qab no, cov twj centrifugal yuav tsum siv ntau li ntau tau:
Thaum metering yuav tsum tau siv lub twj tso kua mis metering.
Thaum qhov yuav tsum tau nqa yog siab heev, tus nqi ntws tsawg heev thiab tsis muaj qhov haum me me siab nqa centrifugal twj tso kua mis xaiv, lub twj tso kua mis reciprocating tuaj yeem siv, thiab lub twj tso kua mis vortex kuj tseem siv tau thaum qhov kev xav tau cavitation tsis siab. . Thaum lub taub hau qis heev thiab tus nqi ntws loj, Axial flow twj tso kua mis thiab cov twj tso kua mis sib xyaw.
Thaum lub viscosity ntawm qhov nruab nrab yog siab (ntau tshaj 650 ~ 1000mm2 / s), lub rotor twj tso kua mis los yog reciprocating twj tso kua mis (iav twj tso kua mis, ntsia hlau twj tso kua mis) tuaj yeem txiav txim siab.
Thaum cov roj cov ntsiab lus ntawm qhov nruab nrab yog 75 feem pua, tus nqi ntws me me thiab cov viscosity tsawg dua 37.4mm2 / s, lub twj tso kua mis vortex tuaj yeem xaiv.
Rau lub sijhawm uas nquag pib lossis twj tso kua mis tsis yooj yim, cov twj uas muaj kev ua haujlwm ntawm tus kheej yuav tsum tau xaiv, xws li cov twj centrifugal tus kheej, cov twj tso kua mis tus kheej, thiab pneumatic (hluav taws xob) diaphragm twj.
