Feem ntaumechanical ncej sealsmuaj nyob rau hauv ob qho tib si sib npaug thiab tsis sib npaug.Ob leeg muaj lawv qhov zoo thiab qhov tsis zoo.
Qhov sib npaug ntawm lub foob yog dab tsi thiab yog vim li cas nws thiaj li tseem ceeb raumechanical foob?
Qhov sib npaug ntawm lub foob txhais tau hais tias kev faib cov khoom hla ntawm lub foob ntsej muag.Yog tias muaj kev thauj khoom ntau dhau ntawm lub ntsej muag foob, nws tuaj yeem ua rau cov kua dej tawm hauv lub foob uas qhov tseem ceeb ua rau lub foob tsis muaj txiaj ntsig.Ntxiv mus, cov kua zaj duab xis nyob nruab nrab ntawm lub foob rings khiav txoj kev pheej hmoo ntawm vaporizing.
Qhov no tuaj yeem ua rau hnyav dua thiab rhuav tshem lub foob, ua rau nws lub neej luv.Yog li ntawd, qhov sib npaug yog qhov tsim nyog kom tsis txhob muaj kev puas tsuaj thiab ua kom lub neej ntev ntawm lub foob.
Balanced Seals:
Lub foob sib npaug muaj qhov txwv ntau dua ntawm qhov siab.Nws txhais tau hais tias lawv muaj peev xwm loj dua rau lub siab thiab lawv kuj tsim kom muaj cua sov tsawg.Lawv tuaj yeem tuav cov kua dej uas muaj lubricity tsawg zoo dua li cov ntsaws ruaj ruaj tsis sib npaug.
Unbalanced Seals:
lub caij no,unbalanced mechanical sealsfeem ntau ruaj khov dua li lawv cov sib npaug sib npaug li deb li kev vibration, cavitation thiab misalignment muaj kev txhawj xeeb.
Tsuas yog lub ntsiab drawback uas lub foob tsis sib npaug tshwm sim yog qhov kev txwv qis.Yog tias lawv tau muab tso rau hauv qhov siab me ntsis ntau dua li lawv tuaj yeem nqa tau, cov yeeb yaj kiab ua kua yuav vaporise sai thiab yuav ua rau lub foob khiav kom qhuav thiab yog li ua tsis tiav.
Qhov sib txawv ntawm cov khoom sib npaug thiab tsis sib npaug:
• Balanced Seals = Tsawg dua 100%
Cov ntsaws ruaj ruaj muaj qhov sib npaug sib npaug uas tsawg dua 100 feem pua, feem ntau, lawv nyob nruab nrab ntawm 60 thiab 90 feem pua.
• Cov ntsaws ruaj ruaj tsis sib npaug = Ntau tshaj 100%
Cov ntsaws ruaj ruaj tsis sib npaug muaj qhov sib npaug sib npaug uas ntau dua 100 feem pua, feem ntau, lawv nyob nruab nrab ntawm 110 thiab 160 feem pua.
Yog tias koj tsis muaj lub tswv yim ntawm cov tshuab foob uas tsim nyog rau lub twj tso kua mis, koj tuaj yeem tiv tauj peb kom paub meej ntxiv, peb yuav pab xaiv cov khoom siv kho tshuab kom raug.
