Kev ruaj ntseg lim tsim thiab xam kev xaiv

Cov lim dej ruaj ntseg feem ntau yog siv los tshem tawm cov khoom me me (xws li cov khib nyiab tshem tawm, colloids, kab mob, thiab lwm yam) los ntawm cov kua los tiv thaiv cov khoom siv hauv qab (xws li rov qab osmosis membranes, ion exchange resins, thiab lwm yam). Lawv cov qauv tsim thiab kev xaiv yuav tsum muaj kev saib xyuas zoo ntawm cov khoom xws li cov khoom siv dej, pom tseeb, ntws tus nqi, siab poob, thiab cov khoom sib xws. Cov hauv qab no yog cov kauj ruam tseem ceeb thiab cov ntsiab lus tseem ceeb ntawm kev tsim thiab kev suav xaiv:

1. Txhais cov kev xav tau lim

Lim Media: Kua (dej, roj, tshuaj tov).

Target Contaminants: Particle yam (xws li, silt, xeb, kab mob), particle size range, concentration.

Filtration Accuracy: Feem ntau 1 ~ 100 microns (feem ntau 1μm, 5μm, 10μm), txiav txim siab raws li cov khoom siv hauv qab.

Flow Rate Requirements: Qhov siab tshaj plaws / tsawg kawg nkaus (m³ / h lossis L / min).

Kev Ua Haujlwm: Kub, siab (ua haujlwm siab thiab siab tshaj plaws tiv taus siab), pH tus nqi, tshuaj lom neeg sib xyaw.

2. Xaiv hom lim

Cartridge Filter: Haum rau siab -precision, qis-flow scenarios (xws li, rov qab osmosis pretreatment).

Lub hnab lim: haum rau siab txaus thiab nruab nrab precision (10 ~ 100μm).

Candle Filter: Haum rau kev tshaj tawm nrog cov viscosity siab lossis cov ntsiab lus siab.

Tus kheej-Ntev Lim: Haum rau cov xwm txheej uas xav tau kev siv tshuab siab thiab kev saib xyuas tsawg.

3. Kev xaiv cov khoom siv

Lim Cartridge: Polypropylene (PP), Polytetrafluoroethylene (PTFE), Nylon, Sintered Hlau.

Plhaub Khoom: Stainless Hlau (304/316L), Carbon Steel (nrog rau kev tiv thaiv -corrosion hauv ob sab phlu), PP / UPVC (corrosion resistant).

Sealing Khoom: EPDM, Silicone, Fluororubber (xaiv raws li cov khoom siv tshuaj lom neeg).

4. Kev txiav txim siab lim Cartridge Parameters

Pom qhov chaw: Txiav txim siab av tuav lub peev xwm thiab kev poob siab; yuav tsum tau xam tus nqi ntws.

Lim Cartridge Length: Cov qauv loj yog 10 nti, 20 nti, 30 nti, thiab 40 nti.

Hom kev sib txuas: Chuck type, Threaded type, Flange type.

1. 1. Kev xam cheeb tsam lim

A: Tag nrho cheeb tsam pom (m²);

Q: Tus nqi ntws (m³ / h);

V: Lim tawm tshaj tawm (m / h), feem ntau 0.1 ~ 0.3 m³ / (m²·h) (kho raws li lim xov xwm hom);

η: Lim cartridge siv tus nqi (feem ntau 0.8 ~ 0.9).

2. Lim Cartridge kom muaj nuj nqis

N: Lim cartridge kom muaj nuj nqis;

A (ib zaug): Siv tau zoo pom thaj tsam ntawm ib lub lim cartridge (muab los ntawm cov chaw tsim khoom, piv txwv li, 0.5 ~ 1.5 m² / cartridge).

3. Kev kwv yees poob siab

▲ P: Pib siab poob (Pa);

μ: kua viscosity (Pa·s);

L: Lim cartridge thickness (m);

K: Lim xov xwm permeability coefficient (m², xav tau kev sim lossis cov ntaub ntawv tsim khoom).

Nco tseg: Qhov tseeb siab poob yuav nce nrog cov kab mob sib kis; yuav tsum muaj kev nyab xeeb ntawm 1.5 ~ 2 zaug.

4. Dirt Holding Capacity suav nrog

C: Dirt Holding Capacity (g);

ρ: Qhov ntom ntom (g / m³);

V: Lim Cartridge Volume (m³);

ηc: Lim Cartridge Porosity (muab los ntawm cov chaw tsim khoom, piv txwv li, 60% ~ 90%)

Filtration Accuracy Matching: Cov khoom siv hauv qab yuav tsum muaj: Piv txwv li, rov qab osmosis systems yuav tsum muaj qhov tseeb tsawg dua 5μm. Kev faib tawm tiag tiag: Xaiv cov qib raug tsim nyog los ntawm kev ntsuas particle counter.

Flow Rate thiab Pressure Drop Balance: Kev khiav dej num ntau dhau yuav ua rau muaj kev poob siab ntau dhau los lossis luv luv lim cartridge lub neej. Xaiv cov naj npawb thiab cheeb tsam ntawm cov lim cartridges raws li qhov kev txwv qhov system.

Chemical Compatibility Verification: Lim xov xwm thiab sealing cov ntaub ntawv yuav tsum tau resistant rau media corrosion (saib rau tshuaj compatibility pov thawj). (Chemical Compatibility Table).

Kev tu thiab kev siv tus nqi kom zoo: Lim Hloov Ntau zaus: Rau siab - cov xwm txheej sib kis, xaiv loj - lim lim lossis tus kheej - qauv tsim. Kev lag luam: Sib piv cov nqi ntev - cov nqi ntawm cov lim dej pov tseg thiab ntxuav tau.

Ua ntej- Kev Tiv Thaiv Kev Pom Zoo: Nruab lub lim lim (piv txwv li, 100μm) ua ntej lim kev ruaj ntseg kom ntev lub neej lim.

Kev tso pa tawm thiab tso dej: Kev tsim vaj tsev yuav tsum xav txog qhov tso pa tawm thiab cov dej ntws tawm kom tsis txhob muaj huab cua thaiv thiab sedimentation.

Validation Testing: xeem dhau qhov ntsuas npuas taw tes (kom paub tseeb qhov tseeb ntawm cov lim dej) thiab qhov ntsuas particle rejection rate test.

Kev Nyab Xeeb Kev Nyab Xeeb: Nws raug nquahu kom muaj 10% ~ 20% ntau lim cartridges los tiv thaiv kev sib kis tam sim lossis kev hloov pauv.
