Hauv pneumatic conveying thiab hmoov tuav tshuab, arotary airlock valveTsis tsuas yog meters cov ntaub ntawv ntws tab sis, qhov tseem ceeb tshaj, tswj qhov system airtightness thiab tiv thaiv kom tsis txhob muaj siab. Kev xaiv tsis zoo tuaj yeem txo qhov kev ua tau zoo ntawm kev xa khoom, thiab hauv qhov xwm txheej hnyav, ua rau muaj kev cuam tshuam hauv lub cev, cov khoom siv hnav, lossis txawm tias muaj kev pheej hmoo ntawm kev nyab xeeb.
Rau cov kws tshaj lij thiab cov kws tsim khoom, qhov kev sib tw tiag tiag tsis yog tsuas yog nrhiav lub valve, tab sis xaiv qhov yog. Cov lus qhia no suav nrog cov xwm txheej ntawm daim ntawv thov, qhov tsis tseem ceeb, kev tsim qauv, thiab kev lag luam kev coj ua zoo tshaj plaws los qhia meej txog kev xaiv cov logic rau cov tshuab ua teb airlock.
Koj cov kev ua haujlwm yog dab tsi?
Cov kev ua haujlwm sib txawv ua rau muaj qhov sib txawv loj heev ntawm cov tshuab ntsuas cua tshuab. Ua ntej xaiv, ntsuas cov nram qab no kom zoo zoo.
1. Hom Conveying System
- Zoo siab conveying
- Tsis zoo siab conveying
- Lub ntiajteb txawj nqus tawm
Cov kev xav tau huab cua nruj sib txawv raws li qhov system. Piv txwv li, lub tshuab tsis zoo siab xav tau ntau dua sealing kev ua tau zoo kom tsis txhob muaj cua nkag sab nraud, uas cuam tshuam rau kev ruaj ntseg.
2. Cov yam ntxwv ntawm cov khoom (Qhov tseem ceeb tshaj plaws)
Tsom ntsoov rau cov khoom tseem ceeb no:
- Particle loj (hmoov / granular / lumpy)
- Flowability (nrog rau kev txuas los yog tsis)
- Abrasiveness (piv txwv li, silica hmoov, ntxhia hmoov)
- Adhesiveness (xws li, hmoov qab zib, tshuaj hmoov)
- Cov ntsiab lus noo noo, kub, thiab corrosiveness
Piv txwv:
Cov ntaub ntawv abrasive heev yuav tsum hnav- tiv thaiv kev tsim kho lossis cov ntaub ntawv tshwj xeeb.
Cov ntaub nplaum nplaum yuav tsum tau tiv thaiv - tus qauv tsim los yog tus kheej - ntxuav cov qauv.
3. Kev lag luam thov ib puag ncig
Cov kev lag luam sib txawv muaj cov kev xav tau ntxiv:
Kev lag luam zaub mov:Ua raws li cov qauv kev nyiam huv (stainless steel, yooj yim tu).
Pharmaceutical kev lag luam:Kev sib khi siab, kev sib kis -dawb tsim, thiab ua raws GMP.
Cement / Mining kev lag luam:Hais txog kev hnav tsis kam.
Kev lag luam tshuaj:Muaj peev xwm ATEX tawg - cov ntaub ntawv pov thawj.
Cov Kev Xaiv Cov Ntsiab Cai rau Rotary Airlock Valves
Thaum cov txheej txheem kev khiav hauj lwm raug txhais, ntsuas cov kev ntsuas tseem ceeb no.
1. Muaj peev xwm tuav tau
- Ntsuas raws li volumetric flow (m³ / h) lossis huab hwm coj (kg / h, t / h).
- Base xaiv ntawm qhov tseeb conveying tus nqi.
- Khaws cia10%–20%system margin rau yav tom ntej expansion.
- Peev xwm yog txiav txim los ntawm rotor ntim thiab rotor ceev.
2. Rotor Tsim
Hom hom:
- Qhib rotor
- Kaw rotor
- V- hom rotor (zoo tagnrho rau cov nplaum, kev sib txuas- cov ntaub ntawv yooj yim nrog kev ua haujlwm zoo heev - nplaum)
Rotor tsim ncaj qha cuam tshuam kev sib khi, kev huv, thiab cov khoom siv sib xws.
3. Seal Clearance
Qhov sib txawv ntawm rotor thiab vaj tse cuam tshuam:
- Airtightness
- Kev pab lub neej thiab hnav tus nqi
Txoj cai dav dav:
- Cov khoob me me=zoo dua sealing.
- Cov qhov khoob loj dua=zoo dua rau cov khoom siv abrasive, txo cov jamming thiab hnav.
Rau siab - daim ntawv thov kev ua tau zoo, xaiv airtight lossis hnyav - lub luag haujlwm airlock tsim.
4. Kev sib hloov ceev
Kev ceev tsis raug ua rau muaj teeb meem:
Siab dhau:Cov khoom degradation thiab nrawm hnav.
Tsawg dhau:Kev xa tawm tsis txaus thiab cov khoom ntim khoom.
Optimize ceev raws li cov khoom siv, tus nqi ntws, thiab lub zog siab.
5. Ua haujlwm siab
Qhov tseem ceeb hauv pneumatic conveying systems:
Yam ntau yam:0.1-1 bar (g); siab dua rau cov ntawv thov hnyav -.
Xyuas kom lub cev valve thiab sealing tsim tuaj yeem tiv taus qhov system siab.
Kev tsim kho thiab kev xaiv cov khoom siv: Txiav txim siab kev pab cuam lub neej thiab kev ruaj ntseg
1. Khoom siv ntawm kev tsim kho
- Carbon steel:General -lub hom phiaj, tus nqi- zoo.
- Stainless hlau (304/316L):Khoom noj khoom haus, tshuaj, thiab siab - daim ntaub ntawv purity.
- Hnav- tiv taus txheej / alloy:High abrasive ib puag ncig (mining, cement).
2. Hnav-Resistant Design
Rau cov ntxhia hmoov, cement, thiab cov ntaub ntawv zoo sib xws:
- Replaceable hnav liners
- Kev kho deg hardening
- Ceramic txheej los yog tawv alloy txau
3. Anti-Jamming Design
Kev daws rau cov ntaub ntawv nyuaj:
- Shear hniav qauv
- Elastic them nyiaj rotor
- Rov qab rotation rau blockage clearing
Cov Kev Xav Tau Tshwj Xeeb: Feem ntau Overlooked Key Points
1. Kev tawg-Cov pov thawj (ATEX)
Rau cov plua plav tawg ib puag ncig (cov hmoov nplej, hmoov txhuv nplej siab, tshuaj hmoov, hmoov txhuas), paub meejATEX ntawv pov thawj.
2. Kev tu thiab tu
Qhov tseem ceeb rau zaub mov / tshuaj lag luam:
- Ceev -disassembly qauv
- CIP (Clean-hauv-Place) / SIP (Sterilize-hauv-Place) muaj peev xwm
- Sab hauv tuag-chaw-dawb tsim
3. Hom tsav
- Direct-coupled lub cev muaj zog
- Iav txo lub cev muaj zog
- Chain / siv tsav
Kev xaiv tsav cuam tshuam rau tus nqi tu, kev ua haujlwm ruaj khov, thiab qhov chaw teeb tsa.
Common Selection yuam kev kom zam
- Kev tsom mus rau tus nqi nkaus xwb, tsis quav ntsej daim ntawv thov sib piv.
- Saib xyuas cov khoom tseem ceeb (adhesiveness, abrasiveness, flowability).
- Ua tsis tiav rau kev nthuav dav lub peev xwm yav tom ntej.
- Tsis quav ntsej cov kev cai sealing, txo qhov system efficiency.
- Tsis lees paub qhov tawg - pov thawj lossis zaub mov- qib ua raws.
Cov teeb meem no feem ntau tshwm sim 3-6 lub hlis tom qab ua haujlwm.
Cov tswv yim tswv yim rau kev xaiv ceev thiab raug
Muab cov ntsiab lus no rau cov neeg muag khoom kom paub meej cov lus pom zoo:
- Hom khoom (lub npe + khoom: particle loj, flowability, abrasiveness, adhesiveness, noo noo cov ntsiab lus)
- Kev xa tawm tus nqi (t / h, kg / h, lossis m³ / h)
- Hom system (zoo / tsis zoo siab)
- Ua hauj lwm siab
- Kev lag luam (khoom noj / tshuaj / mining, thiab lwm yam)
- Cov cai tshwj xeeb (kev tawg- pov thawj / hnav- tiv taus / tu cev)
Cov ntaub ntawv tiav ua kom muaj kev xaiv raug.
Xaus
Xaiv lub teb valve yog hais txog qhov sib txuam ntawm kev ua haujlwm thiab cov khoom siv, tsis yog kev yuav khoom xwb. Qhov zoo tagnrho valve balances:
- Kev xa tawm nrog qhov xav tau qhov system
- Airtightness rau pneumatic conveying
- Cov qauv tsim rau cov yam ntxwv ntawm cov khoom
- Cov khoom zoo rau lub sijhawm ntev - kev ntseeg tau
Xaiv ib tus neeg muag khoom paub txog yog qhov tseem ceeb tshaj qhov sib piv cov nqi ib leeg.
