Mavavu Agulugufe Ofewa Okhazikika Pawiri (Mtundu Wa Shaft Wouma)

Tanthauzo la Zamalonda

Makhalidwe Ofunika Kwambiri

1. Kapangidwe ka Double Eccentric
   • Eccentricity Yoyamba: Thevalavushaft imachotsedwa pakati pa diski, kuchepetsa kukangana pakutsegula / kutseka ndi kuchepetsa kuvala pamalo osindikizira.
   • Kukhazikika Kwachiwiri: Shaft imachotsedwanso kuchokera papaipi yapakati, ndikupanga "kuwotcha" komwe kumawonjezera kusindikiza pamene disc ikutseka.
   • Phindu: Amapereka kudalirika kosindikiza kwapamwamba komanso kumatalikitsa moyo wautumiki poyerekeza ndi mapangidwe ang'onoang'ono kapena okhazikika.
2. Njira Yofewa Yosindikizira
   • Valve imagwiritsa ntchito mphete yosindikizira yofewa (yomwe imapangidwa ndi EPDM, NBR, kapena PTFE) yomwe imayikidwa mu valavu ya valve kapena disc, kuonetsetsa kuti kutsekedwa kwa mpweya ndi kugwirizana ndi zofalitsa zosiyanasiyana (mwachitsanzo, madzi, mafuta, mpweya, ndi madzi osakanizika).
   • Ubwino: Miyezo yotsika yotayikira (yokumana ndi miyezo ya API 598 kapena ISO 15848) ndi torque yochepa yofunikira kuti igwire ntchito.
3. Dry Shaft Construction
   • Shaft imasindikizidwa mosiyana ndi kutuluka kwa media, kuteteza kukhudzana mwachindunji ndi madzimadzi. Kapangidwe kameneka kamachotsa njira zotayikira zomwe zingadutse mutsindemo ndikuchepetsa zoopsa za dzimbiri, makamaka m'malo ovuta.
   • Chigawo Chofunikira: Zisindikizo zamtengo wapatali (mwachitsanzo, kulongedza kwa mtundu wa V kapena zosindikizira zamakina) zimatsimikizira kuti ziro sizitayikira pambali pa shaft.
4. Kugwirizana kwa Flange
   • Zopangidwa ndi mawonekedwe a flange (monga, ANSI, DIN, JIS) kuti aziyika mosavuta pamapaipi. Mapangidwe a flanged amapereka kukhazikika kwapangidwe komanso kumathandizira kukonza.

Mfundo Yogwirira Ntchito

• Kutsegula: Pamene kutsinde kumazungulira, theawiri-eccentricdisc imayenda kuchokera pamalo otsekedwa, pang'onopang'ono kuchoka ku chisindikizo chofewa. Ma eccentric offsets amachepetsa kupsinjika koyambirira, kupangitsa kuti pakhale ntchito yosalala, yotsika.
• Kutseka: Diskiyo imazungulira mmbuyo, ndipo geometry yawiri-eccentric imapanga ntchito yosindikiza pang'onopang'ono. Kuchita kwaukwati kumawonjezera kukhudzana pakati pa diski ndi chisindikizo, kuonetsetsa kuti kutsekedwa kolimba.
• Zindikirani: Mapangidwe a shaft youma amawonetsetsa kuti shaftyo imakhalabe yosakhudzidwa ndi kutentha kwa media, kupanikizika, kapena kuwononga, kumapangitsa kudalirika kwathunthu.

Mfundo Zaukadaulo

• Kuchiza Madzi: Madzi akumwa, madzi otayira, ndi zonyansa (zimafunika kusindikiza kwambiri pamiyezo yaukhondo).
• Makampani Opanga Mankhwala: Zinthu zamadzimadzi zowononga, ma asidi, ndi ma alkalis (tsinde louma limateteza ku kugwidwa ndi mankhwala).
• Ma HVAC Systems: Kuwongolera mpweya ndi mapaipi otentha (ma torque otsika kuti azigwira ntchito pafupipafupi).
• Petrochemical & Mafuta / Gasi: Makanema osasokoneza ngati mafuta, gasi, ndi zosungunulira (zodalirika zotsekera m'njira zovuta).
• Chakudya & Chakumwa: Ntchito zaukhondo (zisindikizo zovomerezeka ndi FDA zimatsimikizira chitetezo chazinthu).

• Ubwino Woposa Mavavu Achikhalidwe

  • Kusindikiza Kwapamwamba: Zisindikizo zofewa zimachotsa kutayikira, zoyenera kugwiritsa ntchito zomwe zimafuna kutetezedwa kwa chilengedwe kapena kuyera kwambiri.
  • Mphamvu Zamagetsi: Kugwiritsa ntchito torque yochepa kumachepetsa mphamvu zamagetsi, kutsitsa mtengo wogwirira ntchito.
  • Utali wautali: Mapangidwe amitundu iwiri amachepetsa kuvala, pomwe shaft yowuma imateteza ku dzimbiri, kukulitsa moyo wautumiki.
  • Kupulumutsa Malo: Kapangidwe kakang'ono poyerekeza ndi ma valve a zipata kapena zapadziko lonse lapansi, abwino pakuyika kwa malo ochepa.

  Malangizo Okonzekera & Kuyika

  • Kuyika: Onetsetsani kuti ma flanges alumikizidwa ndipo ma bolt amamangika mofanana kuti apewe kupsinjika pathupi la valve.
  • Kusamalira: Yang'anani nthawi zonse chisindikizo chofewa kuti chitha kuvala ndikuchisintha ngati chawonongeka. Onjezani shaft ndi actuator nthawi ndi nthawi kuti muwonetsetse kuti ikuyenda bwino.
  • Kusungirako: Sungani pamalo owuma, opanda fumbi ndi valavu yotseguka pang'ono kuti muchepetse kupsinjika kwa chisindikizo.
  Valve iyi imaphatikiza umisiri wotsogola ndi mapangidwe othandiza, opereka njira yodalirika komanso yotsika mtengo pazosowa zamakono zowongolera kayendedwe ka mafakitale. Kuti musinthe mwamakonda (mwachitsanzo, kukweza kwazinthu kapena zokutira zapadera), chonde funsani wopanga.
