Yuav Ua Li Cas Xaiv Lub Tshuab Cua Diaphragm Rau Kev Siv Khoom Siv: Ib Daim Ntawv Qhia Kev Xaiv Ua tiav

Dab tsi yog Air Diaphragm Pump?

Ibcua diaphragm twj tso kua mis(tseem hu ua pneumatic diaphragm twj tso kua mis lossis AODD twj tso kua mis) yog ib hom twj tso kua mis zoo uas siv cov cua compressed los ntawm nws lub zog. Tsis zoo li cov twj siv hluav taws xob, cua diaphragm twj ua haujlwm tsis muaj hluav taws xob, ua rau lawv muaj kev nyab xeeb rauexplosive, flammable, thiab txaus ntshai ib puag ncig. Lub twj tso kua mis ua haujlwm los ntawm kev sib txuas lus ntawm lub diaphragm hloov tau, uas tsim lub tshuab nqus tsev thiab lub voj voog kom txav cov kua dej los ntawm lub cev.

Cua diaphragm twj siv dav siv thoob plaws kev lag luam suav nrogKev siv tshuaj lom neeg, khoom noj khoom haus thiab dej haus, kev tsim tshuaj, roj thiab roj, mining, thiab kev kho dej khib nyiab. Lawv lub peev xwm los tuav cov kua dej corrosive, abrasive slurries, thiab cov ntaub ntawv khov ua rau lawv yog ib qho ntawm cov kev daws teeb meem zoo tshaj plaws.

Yam Tseem Ceeb Hauv Kev Xaiv Cua Diaphragm Pump

1. Flow Rate Requirements

Flow rate feem ntau yog thawj qhov tshwj xeeb los xav txog thaum xaiv ib qhocua diaphragm twj tso kua mis. Ntsuas hauv litres ib feeb (L / min) lossis nkas loos ib feeb (GPM), tus nqi ntws yuav tsum nyob ntawm koj daim ntawv thov ntim qhov xav tau. Cov twj tso kua mis me me (xws li 150 qauv) xa mus txog 340 L / min, thaum loj 2-nti qauv tuaj yeem tshaj 651 L / min.

• Batch processing:Xam tag nrho ntim muab faib los ntawm lub sijhawm ua haujlwm
• Kev hloov mus tas li:Sib tw twj tso kua mis ntws tus nqi mus rau downstream noj tus nqi
• Recirculation:Qhov tseem ceeb hauv kev xa rov qab thaum lub twj tso kua mis kaw - lub voj voog

2. Pump Size thiab Port Diameter

Cua diaphragm twj tso kua mis tuaj nyob rau hauv tus qauv qhov ntau thiab tsawg teev los ntawm lawv inlet / qhov hluav taws xob qhov chaw nres nkoj txoj kab uas hla:

3. Cov khoom siv sib xws

Cov ntaub ntawv ntub dej ntawm lub twj tso kua mis cua diaphragm yuav tsum sib haum nrog cov kua uas tau muab tso rau. Kev xaiv cov khoom siv feem ntau muaj xws li:

• Stainless hlau (SS304 / SS316):Zoo tagnrho rau cov tshuaj corrosive, zaub mov-qib daim ntawv thov, thiab cov txheej txheem tshuaj
• Aluminium:Lub teeb yuag thiab tus nqi- zoo rau kev siv dav hauv kev lag luam, kev hloov pauv hnyav, thiab kev tsim kho
• Polypropylene (PP):Cov tshuaj tiv thaiv zoo heev rau cov kua qaub, alkalis, thiab tshuaj lom neeg
• PVDF (Kynar):Cov tshuaj tiv thaiv zoo tshaj plaws rau kev txhoj puab heev lossis kev siv tshuaj dawb huv

Kev xaiv cov khoom siv Diaphragm yog qhov tseem ceeb sib npaug. Cov khoom siv diaphragm feem ntau suav nrogSantoprene, Buna-N (Nitrile), EPDM, PTFE, thiab Hytrel, txhua qhov muab cov qib sib txawv ntawm cov tshuaj tiv thaiv, qhov kub thiab txias, thiab lub neej flex.

4. Huab cua siab thiab cua siv

Cua diaphragm twj tso kua mis feem ntau ua haujlwm ntawm huab cua siab nruab nrab ntawm0.2-0.75 MPa (2-7.5 bar). Cov huab cua siab dua ua rau nce tus nqi ntws thiab tso tawm lub taub hau tab sis kuj ua rau huab cua ntau ntxiv. Cov ntsiab lus tseem ceeb suav nrog:

• Muaj compressed cua muab siab ntawm koj qhov chaw
• Cua compressor muaj peev xwm los txhawb kev ua haujlwm twj tso kua mis tas mus li
• Tus nqi zog ntawm cov cua compressed (pneumatic twj siv 3-5 npaug zog ntau dua li cov twj siv hluav taws xob rau kev ua haujlwm sib npaug)
• Lub suab nrov - xav txog kev xaiv muffler rau kev ua haujlwm ntsiag to

5. Viscosity thiab khoom tuav

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov twj cua diaphragm yog lawv lub peev xwm los tuavviscous fluids thiab suspended solids. Thaum xaiv lub twj tso kua mis rau cov kua dej sib tw:

• Rau cov kua dej uas muaj txog li 6.4 hli, cov twj tso kua mis txheem yog txaus
• Rau cov khoom loj dua (txog 9.5mm), xaiv qhov chaw nres nkoj loj dua qauv
• Rau cov ntaub ntawv muaj kuab heev (tshaj 10,000 cP), xav txog cov twj loj dua diaphragm rau kev ua haujlwm zoo dua
• Rau shear- cov ntaub ntawv rhiab heev, xyuas kom lub twj tso kua mis khiav ceev tsis ua rau cov khoom zoo

Muaj kev siv ntawm Cua Diaphragm Twj

Kev ua tshuaj lom neeg

Hauv cov nroj tsuag tshuaj, huab cua diaphragm hloov pauvcorrosive acids, caustic daws, kuab tshuaj, thiab tshuaj reactive. Lawv lub foob-tsim tsim tsawg tshem tawm qhov txaus ntshai, thiab lawv qhov tawg- pov thawj kev ua haujlwm (tsis muaj hluav taws xob hluav taws xob) ua rau lawv muaj kev nyab xeeb rau thaj chaw tshuaj lom neeg tsis zoo. Stainless hlau los yog PVDF qauv nrog PTFE diaphragms yog feem ntau teev.

Khoom noj khoom haus thiab dej haus

Khoom noj khoom haus- qib cua diaphragm twj tuavkua txiv hmab txiv ntoo, syrups, khoom noj siv mis, kua ntses, thiab cov khoom xyaw. Ua raws li FDA thiab cov qauv kev tu cev yog qhov tseem ceeb. Cov twj tso kua mis no muab cov khoom siv yooj yim, yooj yim huv -hauv- qhov chaw (CIP) muaj peev xwm, thiab muaj peev xwm khiav kom qhuav yam tsis muaj kev puas tsuaj.

Pharmaceutical Manufacturing

Kev siv tshuaj xav taukev kis kab mob- hloov pauv kua dej dawbrau cream, tshuaj pleev, volatile compounds, thiab pastes. Electropolished stainless hlau twj tso kua mis nrog kev sib txuas huv huv kom ua raws li GMP cov cai.

Roj thiab Roj

Nyob rau hauv cov roj thiab roj sector, cua diaphragm twj siv rauKev hloov pauv roj av, tshuaj txhaj tshuaj, tsim cov dej pov tseg, thiab kho cov kav dej. Lawv qhov tawg -cov ntaub ntawv pov thawj yog qhov tseem ceeb rau cov chaw ua haujlwm sab nrauv thiab cov chaw ua kom zoo nkauj uas muaj cov cua kub hnyiab.

Kev kho dej thiab dej khib nyiab

Cua diaphragm twj tso kua mis ua tau zoo ntawmKev hloov pauv sludge, tshuaj siv tshuaj, thiab siv dej pov tseg. Lawv lub peev xwm los lis cov khib nyiab abrasive thiab khiav qhuav ua rau lawv zoo tagnrho rau kev xav tau kev kho mob nroj tsuag.

Qhov zoo ntawm Air Diaphragm Pumps Over Electric Pumps

• Intrinsically nyab xeeb:Tsis muaj hluav taws xob hluav taws xob, haum rau ATEX / Zone 1 thaj chaw muaj kev phom sij
• Dry run peev:tuaj yeem ua haujlwm yam tsis muaj dej tsis muaj kev puas tsuaj
• Tus kheej -priming:Suction qhov siab txog li 8.3 meters tsis muaj priming sab nraud
• Deadhead muaj peev xwm:Nws tuaj yeem khiav tawm ntawm qhov chaw kaw tsis muaj cua sov

• Kev ua haujlwm submersible:Yuav submerged ncaj qha rau hauv cov kua uas yog pumped

Common yuam kev kom zam

1. Undersizing lub twj tso kua mis:Ib txwm xaiv raws li qhov siab tshaj qhov xav tau ntws thiab viscosity, tsis yog qhov nruab nrab
2. Ignoring diaphragm khoom compatibility:Kev siv cov khoom siv diaphragm tsis raug ua rau ua rau tsis ua tiav ntxov thiab muaj peev xwm ua rau muaj kuab paug
3. Tshaj siab tshaj qhov siab tshaj plaws:Kev khiav hauj lwm siab tshaj 0.75 MPa tuaj yeem ua rau cov diaphragms puas thiab txo lub twj tso kua mis
4. Tsis saib xyuas huab cua zoo:Moisture thiab particulates nyob rau hauv compressed cua puas lub twj tso kua mis li qub thiab nce nqi txij nkawm
5. Overlooking suction lift condition:High suction lifts nrog viscous kua yuav tsum tau ceev faj xaiv lub twj tso kua mis thiab kev npaj installation

Cov Tswv Yim Kho Kom Zoo Rau Lub Neej Ua Haujlwm Ntev

• Tshawb xyuas diaphragms tsis tu ncua rau kev tawg, hnav, lossis deformation - hloov ua ntej tsis ua haujlwm
• Kos lub pob valve thiab lub rooj zaum rau hnav - cov no yog cov feem ntau hloov qhov chaw
• Txhim kho thiab tswj cov kab lim cua thiab cov tswj xyuas kom huv si, qhuav compressed cua
• Saib xyuas muffler mob - icing nyob rau hauv qhov chaw ntub dej tuaj yeem txwv cov pa tawm
• Khaws O-rings lubricated thiab hloov thaum lub sijhawm tu ncua
• Tso cov twj tso kua mis kom tiav ua ntej ncua sij hawm kaw kom tiv thaiv cov khoom tsim
