paub qhov txawv ntawm ib leeg thiab ob lub tshuab foob

Ningbo Xindeng Seals yog tus thawj cojmechanical foobtus neeg muag khoom nyob rau sab qab teb ntawm Tuam Tshoj, txij li xyoo 2002, peb tsis tsuas yog tsom mus rau kev ua txhua yam ntawm cov tshuab foob, tab sis kuj tseem them nyiaj rau kev txhim kho cov cuab yeej cuab tam.

Peb feem ntau tham nrog ib co super engineer nyob rau hauv mechanical foob foob, thiab paub qhov hloov tshiab ntawm seals tech.

Hauv qab no yog cov ntaub ntawv thev naus laus zis zoo kom paub qhov txawv ntawm ib lub tshuab foob thiab ob lub tshuab foob, peb muab cov ntaub ntawv no qhia rau ntau tus neeg paub nws.

Mechanical seals yog cov khoom siv uas kaw cov tshuab ntawm qhov sib hloov (shafts) thiab qhov chaw nyob ruaj khov (tswj vaj tse) thiab yog ib feem tseem ceeb ntawm lub twj tso kua mis. Lawv txoj haujlwm tseem ceeb yog los tiv thaiv cov khoom siv los ntawm kev nkag mus rau hauv ib puag ncig thiab raug tsim los ua ib qho los yog ob lub foob. Qhov txawv ntawm ob yog dab tsi?

IB TUG MECHANICAL SEAL yog dab tsi?

Ib qho kev sib tsoo ib leeg muaj ob qhov chaw tiaj tus uas tau nias ua ke los ntawm lub caij nplooj ntoos hlav thiab swb rau ib leeg. Nruab nrab ntawm ob qhov chaw no yog cov yeeb yaj kiab ua kua uas tsim los ntawm cov khoom siv twj. Cov kua dej no tiv thaiv lub tshuab foob los ntawm kov lub nplhaib nyob ruaj ruaj. Qhov tsis tuaj ntawm cov kua dej no (qhuav khiav ntawm lub twj tso kua mis) ua rau muaj kev sib txhuam kub thiab qhov kawg kev puas tsuaj ntawm lub tshuab foob.

Mechanical seals zoo li xau ib qho vapor los ntawm sab siab siab mus rau sab qis. Cov kua no lubricates lub foob ntsej muag thiab nqus cov cua sov uas tsim los ntawm kev sib txhuam, uas hla lub foob ntsej muag raws li cov kua thiab vaporizes rau hauv qhov chaw. Yog li, nws yog ib qho kev xyaum siv tib lub tshuab foob yog tias cov khoom siv twj tso kua mis ua rau tsis muaj kev pheej hmoo rau ib puag ncig.

DOUBLE MECHANICAL SEAL yog dab tsi?

Ob chav tshuab foob muaj ob lub ntsaws ruaj ruaj nyob rau hauv ib tug series. Lub inboard, los yog "primary foob" khaws cov khoom uas muaj nyob rau hauv lub twj tso kua mis vaj tse. Lub sab nrauv, lossis "secondary seal" tiv thaiv cov kua dej ntws tawm mus rau hauv qhov chaw.

Ob chav mechanical seals muaj nyob rau hauv ob txoj kev:

• Rov qab los
  • Ob lub rotating foob rings yog teem kom deb ntawm ib leeg. Lub lubricating zaj duab xis yog tsim los ntawm cov kua dej barrier. Qhov kev npaj no feem ntau pom nyob rau hauv kev lag luam chemical. Nyob rau hauv cov ntaub ntawv ntawm to, lub barrier kua nkag mus rau hauv cov khoom.
• ntsej muag
  • Lub caij nplooj ntoos hlav loaded rotary foob lub ntsej muag yog teem lub ntsej muag thiab xaub los ntawm qhov kev taw qhia tawm mus rau ib lossis ob qhov chaw nres tsheb. Qhov no yog ib qho kev xaiv nrov rau kev lag luam zaub mov, tshwj xeeb tshaj yog rau cov khoom uas nyiam lo. Nyob rau hauv cov ntaub ntawv ntawm to, lub barrier kua nkag mus rau hauv cov khoom. Yog tias cov khoom raug suav tias yog "kub", cov kua dej barrier ua tus neeg ua haujlwm txias rau lub tshuab foob.

Ob chav mechanical seals feem ntau yog siv rau hauv cov xwm txheej hauv qab no:

• Yog tias cov kua dej thiab nws cov vapors muaj kev phom sij rau tus neeg teb xov tooj lossis ib puag ncig, thiab YUAV TSUM muaj
• Thaum aggressive media yog siv nyob rau hauv high pressures los yog kub
• Rau ntau polymerizing, nplaum xov xwm
