1.Kodi valve yozungulira ya airlock ndi chiyani
Ma valve ozungulira a Airlock amagwiritsidwa ntchito pazitsulo zolimba zogwiritsira ntchito njira zolumikizirana, makamaka ngati kuli kofunikira kupatutsa madera a 2 pansi pazikhalidwe zosiyanasiyana (kupanikizika nthawi zambiri) ndikulola zolimba kuchoka ku chikhalidwe chimodzi kupita ku china.
Ma valve ozungulira, omwe amadziwikanso kuti ma valve a nyenyezi, amagwiritsidwa ntchito kumayambiriro ndi kumapeto kwa zoyendetsa mpweya.Amalola kubweretsa cholimba kuchokera kumadera otsika kwambiri kupita kumalo otsika kwambiri kumayambiriro kwa mzerewo pamene akuthandizira kuchotsa zolimba kuchokera ku mpweya wopita kumapeto kwa mzere.
Ma valve oterowo amatha kupanga dosing wovuta, motero, amathanso kuyikidwa ngati zida za dosing, ngakhale sizochita bwino.
Mitundu iwiri ya ma airlock rotary valves ilipo: dontho kudzera mumtundu ndi kuwomba kudzera pamtundu.Mitundu yonse iwiri ikupereka zotsatira zofanana, komabe, momwe amachitira ndi makhalidwe awo ndi osiyana pang'ono.
Airlock feeders amagwiritsidwa ntchito kwambiri m'makampani ndi ntchito m'magawo awa:
- Makampani opanga zakudya (zophika, mkaka, khofi, tirigu)
- Zomangamanga (simenti, phula)
- Mankhwala
- Migodi
- Mphamvu (zopangira magetsi)
- Mankhwala / Petrochemicals / ma polima
Mfundo zogwirira ntchito za ma Rotary feeders ndi zofunikira zazikulu zaperekedwa pansipa.
2. Dontho Kupyolera mu valavu yozungulira ndi Kuwomba Kupyolera mu valavu yozungulira
Dulani kudzera pa airlock rotary valve
Kugwetsa kudzera mu airlock mavavu ozungulira ndi "kugwetsa" mankhwala ku chitoliro kapena zipangizo pansipa.Pali flange yolowera komanso flange yotuluka.
Onjezani valavu yozungulira ya airlock
Mavavu a nyenyezi amalumikizidwa mwachindunji ndi chingwe chowulutsira.Mpweya womwe umagwiritsidwa ntchito pamzere wotumizira umadutsa mwachindunji ma alveoles a mavavu, ndikusesa chinthucho.
Kawirikawiri, kuwombera ma valve kumagwiritsidwa ntchito ngati pali kutalika kochepa kwambiri kapena pamene mankhwalawa ali ndi chizolowezi chomamatira mkati mwa rotor.Kwa mapulogalamu ena, kutsika kwachitsanzo kumakondedwa kwambiri.
Kukhala ndi rotor molunjika mumayendedwe a chitoliro kungayambitse kusweka kwakukulu kwa chinthu chomwe chikunyamulidwa, makamaka ngati madontho angapo kudzera mu ma valve ali mndandanda muzitsulo zomwezo.Pachifukwa ichi, ma valve otsika amatha kuganiziridwa kuti asunge mankhwala.
3. Star Valve Clearance and Contact kudziwika
Ma valve a nyenyezi amakhala ndi chilolezo chochepa kwambiri pakati pa ma rotor ndi stator, ndikofunikira kuti apereke chisindikizo cha mpweya pakati pa malo okwera ndi otsika omwe sali ofanana.
Chilolezo chodziwika bwino cha ma airlock rotary valves ndi 0.1 mm ndipo nthawi zambiri chimachokera ku 0.05mm mpaka 0.25 mm malingana ndi ntchito yomwe ikuyembekezeka pa valve (kusiyana kwakukulu kwa kuthamanga kuchokera kumbali iliyonse ya valve kapena ayi).Ichi ndi chilolezo chaching'ono chomwe chimafotokoza kuti ma valve ozungulira nthawi zambiri amakhala ndi zokwawa chifukwa cholumikizana ndi rotor / stator.Tebulo ili likufotokoza mwachidule zomwe zimayambitsa kukhudzana.
4. Chitetezo cha kuphulika
Chophimba chozungulira cha airlock chingagwiritsidwe ntchito ngati chinthu chodzipatula kuti chiteteze kuphulika kwa fumbi kufalikira poika.Pazifukwa izi, valavu yozungulira ya airlock iyenera kutsimikiziridwa kuti ndi yosagwirizana ndi kuphulika komanso kutsimikizira malawi.
Kuti izi zitheke, valve iyenera kupangidwa motere:
- Thupi ndi rotor zimatha kupirira kupsinjika kwa kuphulika - nthawi zambiri 10 bar g
- Chilolezo nsonga ya masamba / nyumba ayenera kukhala zosakwana 0.2 mm
- Osachepera masamba a 2 mbali iliyonse ya valavu ayenera kukhudzana ndi nyumbayo (zomwe zikutanthauza kuti masamba onse ayenera kukhala> kapena ofanana ndi 8
5. Rotary Valve Degassing
Chilolezo chochepa chidzalola kusindikiza bwino ndikuchepetsa kutayikira kwa valve airlock.Komabe, ngakhale kuchepetsa kutayikira kudzachitika.Komanso, mpweya wotsekeredwa m'thumba lililonse udzatulutsidwanso pamene thumba lidzatsegulidwa kumalo otsika kwambiri.Izi zimabweretsa kutayikira kwa mpweya.
Kuthamanga kwa mpweya kukuwonjezeka ndi kusiyana kwa kuthamanga ndipo kumawonjezeka ndi liwiro la kuzungulira kwa valve.Zitha kukhala zowononga kwambiri pakugwira ntchito kwa valve, makamaka ndi ufa wopepuka, popeza mpweya womwe umatulutsidwa umapangitsa kuti ufawo ukhale wamadzimadzi ndikuletsa kudzaza thumba.
Chochitika ichi chikhoza kuwonetsedwa muzitsulo zogwirira ntchito za airlock rotary blades : mphamvu idzafika ku assymptot ndipo ngakhale kuchepa pa liwiro lalikulu popeza matumba sangathenso kudzazidwa ndi mankhwala, madzi ochuluka kwambiri kuti akhale ndi nthawi yogwera m'matumba.
Kuti muwongolere izi ndikuwongolera magwiridwe antchito a valavu, mpweya wabwino wa valavu yozungulira uyenera kukhazikitsidwa.Njira yochotsera mpweya imayikidwa pambali yomwe matumba akubwerera kuti awatulutse mumlengalenga asanatenge chatsopano.Njirayi ikutumiza mpweya ku fyuluta kuti itulutsidwe.
6. Kuwerengera kamangidwe ka mavavu a Airlock (kukula kwake)
Kuwerengera mphamvu kwa vavu ya nyenyezi kuti mukwaniritse zomwe mwapatsidwa ndi ntchito ya m'mimba mwake ya valavu ya nyenyezi, liwiro lake lozungulira komanso mtundu wa chinthucho,
- Kukula kwa valavu ya nyenyezi, kukweza kudzakhala mphamvu.
- Liwiro lozungulira kwambiri limatanthawuza kuchita zambiri koma kutulutsa kumasiya kupitilira liwiro linalake
- Kuchuluka kwamadzimadzi kumakhala ufa, kumapangitsa kuti kuchuluke, kumapangitsanso kuti zinthu zopepuka kwambiri zizipangitsa kuti pakhale malire pa liwiro linalake lozungulira. .
7. Mavuto omwe amapezeka ndi ma airlock rotary valves
Mavuto osiyanasiyana amatha kukhudza valavu ya nyenyezi panthawi ya ntchito yake.Mavuto omwe amapezeka ndi awa:
- Kugwira ntchito pansi pamapangidwe (kutsika kochepa kuposa momwe amayembekezera)
- Kuwonongeka ndi kukhudzana kwachitsulo / zitsulo
- Valani
8. Airlock rotary valve kugula kalozera - Momwe mungasankhire valavu yozungulira ya airlock
Airlock rotary valve ikugulitsidwa : Kugula valavu yatsopano yozungulira ya airlock
Mukapeza valavu yatsopano ya airlock ya fakitale yanu, mafunso otsatirawa akuyenera kufunsidwa kuti mugule zolondola:
●Kodi mavavu a airlock rotary ndiabwino ngati kuwomba kapena kutsika?
●Kodi mukufuna chinthu chapadera (mwachitsanzo chitsulo chosapanga dzimbiri) kapena chitsulo chosapanga dzimbiri ndi chokwanira?
● Kodi ndi zotani zomwe mukufunikira komanso kuchuluka kwake kwazinthu zomwe zimayenera kukonzedwa, zidzapereka kukula kwa valve.
●Kodi valavu imaperekedwa ku kutentha?Kodi ikufunika kukhala ndi chilolezo cha rotor stator?
●Kodi valavu ikupita ku chingwe chodutsa mpweya?Kodi ikufunika degassing ?
●Kodi pakufunika kupezeka pafupipafupi poyeretsa mkati mwa vavu?
●Kodi ufawo umatuluka wopanda kapena masamba enaake ndi kapangidwe ka thumba ndikofunikira?
●Kodi valavu yozungulira ya airlock iyenera kutsimikiziridwa kuti ikakonzedwa pamalo ophulika fumbi?Ngati inde, ndi gawo liti lomwe liyenera kuganiziridwa mkati ndi kuzungulira valavu?
●Kodi valavu iyenera kugonjetsedwa ndi kuphulika (nthawi zambiri mipiringidzo 10) ?
Ngati mukufuna ma valavu otsekera ma airlock ndi ma valve diverter mu mizere ya pneumatic conveying, chonde khalani omasuka kutilankhula nafe.
