1. Qhov tseem ceeb ntawm Pump Seals hauv IMO Pumps

Lub twj tso kua mis ntsaws ruaj ruaj yog qhov tseem ceeb rau kev tiv thaiv cov kua dej tawm, txo kev sib txhuam, thiab tswj lub siab hauv cov twj tso kua mis. Hauv IMO twj tso kua mis, uas feem ntau siv nyob rau hauv ib puag ncig hnyav (xws li, dej hiav txwv, tshuaj, thiab kub siab), xaiv txoj cai foob kom:

• Kev Tiv Thaiv Leak- Txo cov dej poob thiab kev sib kis.
• Zog Efficiency- Txo kev sib txhuam, txo qis kev siv hluav taws xob.
• Extended Pump Life- Tiv thaiv kev hnav ntawm cov khoom sib hloov.
• Ua raws li kev nyab xeeb- Ua tau raws li cov qauv kev lag luam rau ib puag ncig txaus ntshai.

Lub foob tsis ua tiav tuaj yeem ua rau raug nqi poob qis, kev puas tsuaj ib puag ncig, thiab khoom puas tsuaj. Yog li ntawd, kev nkag siab txog hom foob yog qhov tseem ceeb rau kev ua haujlwm zoo.

2. Hom IMO Pump Seals

A. Mechanical Seals

Mechanical seals yog cov kev daws teeb meem zoo tshaj plaws rau IMO twj tso kua mis, muab kev tiv thaiv zoo tshaj thiab ua haujlwm ntev.

i. Ib leeg Mechanical Seals

• Tsim: Muaj ob lub ntsej muag sealing thawj (rotating thiab nyob ruaj ruaj).
• Daim ntawv thov: Siv nyob rau hauv lub tshuab siab qis rau nruab nrab (piv txwv li, cov twj tso kua dej, lub teeb roj).
• Qhov zoo:
  • Nqi-zoo
  • Yooj yim rau nruab
  • Haum rau cov kua dej uas tsis muaj teeb meem
• Qhov tsis zoo:
  • Tsis zoo tagnrho rau cov kua dej muaj kuab lom los yog muaj kuab lom

ii. Ob Chav Mechanical Seals

• Tsim: Features ob txheej ntawm sealing ntsej muag nrog ib tug barrier kua nyob rau hauv nruab nrab.
• Daim ntawv thov: Zoo tagnrho rau cov khoom muaj kev phom sij, corrosive, lossis cov kua dej siab (piv txwv li, tshuaj, roj).
• Qhov zoo:
  • Txhim khu kev tiv thaiv
  • Haum rau cov tshuaj lom los yog volatile media
  • Lub neej ntev dua hauv cov xwm txheej hnyav
• Qhov tsis zoo:
  • Tus nqi siab dua
  • Ntau complex installation

iii. Cartridge Mechanical Seals

• Tsim: Pre-assembled unit nrog tag nrho cov khoom foob hauv ib lub tsev.
• Daim ntawv thov: Siv nyob rau hauv kev saib xyuas-hnyav ib puag ncig (xws li, kev ua zaub mov, tshuaj).
• Qhov zoo:
  • Yooj yim hloov
  • Txo kev teeb tsa yuam kev
  • Txhim kho kev ntseeg siab
• Qhov tsis zoo:
  • Tus nqi pib siab dua

B. Lip Seals (Radial Shaft Seals)

• Tsim: Siv daim di ncauj hloov tau yooj yim uas tiv nrog lub ncej kom tiv thaiv kom tsis txhob yaig.

6. Cov lus xaus

Xaiv txoj cai IMO twj tso kua mis yog qhov tseem ceeb rau kev ua haujlwm, kev nyab xeeb, thiab kev ua haujlwm ntev. Mechanical seals (ib zaug, ob npaug, cartridge) yog cov khoom siv ntau yam, thaum lub di ncauj ntsaws ruaj ruaj, lub caj pas ntim, sib nqus cov ntsaws ruaj ruaj, thiab labyrinth seals ua haujlwm rau cov ntawv thov niche. Los ntawm kev txiav txim siab hom dej, siab, qhov kub thiab txias, thiab kev xav tau kev saib xyuas, koj tuaj yeem ua kom zoo dua lub twj tso kua mis thiab txo lub sijhawm poob.
